Philips the brand name, any blind person even suggests you to buy Philip light bulb. Philips has grown its market all over the world. There are tremendous customers who prefer to purchase Philips light bulb only. Philips which stands for quality and integrity. Philips has now dominated the market in every field of electronic. Philips Company founded in1981 by Gerard Philips. He is maternal cousin of Karl Marks, in Eindhoven, the Netherlands.
Light bulb is the first product Philips, and after that Philips went on growing its market in electronic market. Philips light bulb gets a massive response from people. Light bulb which gives light becomes very important in life. Everybody moves toward Philips as the light of day. Amsterdam can be considered a return to the company roots; He made many experiments on making idea of making idea of mass production of light bulbs there. Philips $9 billion lighting division is suddenly on a tear.
There are different kinds of bulb in Philips, one can even order online from Philips sites. There are Incandescent Bulbs, Halogen Bulbs, Compact Fluorescent Bulbs, Fluorescent Bulbs, HID Bulbs, and Specialty Bulbs. Let’s explore on the Incandescent bulb which waste their energy in heat. It is possible to made alternatives from light emitting diodes burn cooler. It produce same amount of illumination while using on an average 40% less electricity. Philips bulb stepped out its vaunted research labs. Now went on buying binge. Philips is going on snapping five companies from the lighting sectors.
Philips this year will definitely provide the light for the annual New Years Eve times Square Ball in New York. The ball will be fitted with above 9500 LEDs as an alternative to incandescent and halogen bulbs. It burn twice as brightly and it can create a palette of 16 million colors. It depends on the color up to 98% more energy efficient than the bulbs they used to replace. Philips used to also supplied the 50 giant LED snowflakes, it makes used to decorate the front of the flagship Sacks Fifth Avenue store in New York. There are 40,000 plus LED which takes much energy as three toaster ovens. It is possible that LED works for more than 11 years, if it is burned for more than 12 hours per day. Philips comes with saving energy bulbs which really helps in keeping Philips light bulb in market. There are millions of consumers of Philips bulbs. If anybody asks for bulb first choice is Philips.

Solar Powered Landscape Lighting
Bob Gambrell asked:
Solar powered landscape lighting is becoming very popular these days and was even featured on Good Morning America, August 28, 2008. There is really no reason to use traditional wired landscape lighting unless there are areas of the garden that just do not get enough sunlight. Solar lighting is powered by the sun and must have some sunlight in order to operate properly. Five hours of sunlight is usually enough to keep the battery charged and ready for operation come nightfall. The lights use a photoelectric cell that turns them on at dusk and off in the morning.
Solar Lights are made from a variety of materials, such as plastic, metal or stainless steel. The lighting mechanism is almost always LED lights. LEDs (Light Emitting Diode) are quite bright, draw very little current and last a very long time, typically up to 50,000 hours. There is a battery to store the power, usually Lithium Ion or more commonly Nickel Metal Hydride. These batteries last about 2 years before they have to be replaced. The very inexpensive plastic lights do not have replaceable batteries, something to consider. There is a small solar panel on top of the light fixture to generate power during the daylight hours to keep the battery charged, so the light will function at night. These lights are very safe and quite easy to install. Just find a location that gets ample sunlight, use the ground mount stake and drive it into the ground. Be careful not to hit the stake with a hammer if it is made of plastic, it may be damaged. Some lights can even be mounted on walls, posts or fences and often come with all of the mounting hardware necessary.
There are a wide variety of lights to choose from as well as a variety of applications. Solar walkway lights, light up paths or walkways. Solar spotlights light up trees and other outdoor features. Solar Shed lights light up remote storage sheds with easy installation and minimal wiring. Solar address lights are self explanatory and there are even patio umbrellas with solar lights for that dinner party on the deck after sunset. The lights usually come in sets but the number of lights in a set varies. Some have two per set; some have four and some six. Prices seem to vary considerably with some sets costing $30 to $40 and others closer to $100. The difference in cost is reflected by the quality and brightness of the lights, how long they will last and styling.
So if you are considering installing solar powered landscape lighting you might want to ask yourself a couple of questions first. Is there enough sunlight to keep the lights powered? What kind of application will they be used for? What kind of styling do I like? Am I looking for lights that will last a long time or do I just need them to last a little while? How and where will I mount the light and is all of the mounting hardware included? There are prices, styles and types for any budget or taste. Solar outdoor lighting is a great way to improve the look of your home and to improve the outdoor safety of your home. They are very easy to install and on top of every thing else, they will lower your energy costs.

What Your LED Flashlight Can Do
Ben Anton asked:
The bright light of an LED flashlight can be an invaluable tool when on a camping or hunting trip, and a potential life saver in a home or car emergency. The power and efficiency of these light sources has made them incredibly popular throughout the world. How did these bright lights become so popular? How does the LED bulb in the flashlight actually work? Science and practicality have come together to create these innovative light sources – it may just be a good idea to know why.
What is an LED?
To understand how an LED flashlight works it is important to understand what an LED light is. LED stands for light-emitting diode. It is a semiconductor diode that emits light when an electric current passes through it, like a simple circuit. This circuit produces electroluminescence, which can be infrared, visible, or ultraviolet, and a number of different colors depending on the make up and condition of the semiconducting material used. These lights are often very small, typically less than 1 mm. Manufacturers usually add special optics or lenses to the chip to help with reflection, creating an incredibly powerful beam for the size of the bulb.
LED lights are embedded in a high-impact epoxy, which makes them virtually indestructible and therefore perfect for handheld lights. There are no loose or moving parts either. LED lights also produce no heat, allowing them to be used for long periods of time without concern of burning out.
LED Light Advantages
LED light technology has certain advantages that help it stand out for flashlight and lamp use – visibility, intensity, color and efficiency.
Visibility
LED lights naturally emit a high level of light, called luminous intensity. This visibility is increased by adding chips to the encapsulation or using secondary optics to distribute light. For most LED flashlights or lanterns, there are a number of individual light sources in a single lens.
Intensity
The intensity of the light is another characteristic of LED lights. The light output varies depending on the type of chip and encapsulation that is used. Although there is no industry standard for LED brightness or intensity, many manufacturers use terminology such as “ultra-bright” or “super-bright” to describe their lights. These lights have such a powerful beam that they can actually do damage to the human eye.
Color and Wavelength
Wavelength and color are other characteristics of LED lights. These lights have a pretty broad wavelength spectrum and thus can produce a number of different colors depending on the phosphorous or other compounds added to the encapsulation. The human eye is most responsive, however, to yellow, orange and red LED lights, probably why many come in those colors.
Efficiency
LEDs are solid-state devices with no moving parts. This allows the average LED light to operate for approximately 100,000 hours at relatively normal ambient temperature (25 degrees C). And unlike other incandescent bulbs, they can be turned on and off without undergoing too much wear and tear.
Putting It All Together
The basic construction of an LED flashlight is pretty straightforward. A simple closed circuit is used to charge the semiconductor diode, producing a brilliant, cool light. These lights illuminate our pathway in the dark, help us during power outages and signal for help. They are tremendous assets to a home, car or supply boxes.

Types of LED Lighting Available on the Market
Imran ali asked:
LED lighting comes in many different types, shapes and sizes for different purposes. It is useful and advantageous in many different fields ranging from simple home décor to architectural design and medical lighting. Many LED industry leaders provide different kinds of LED lights to their customers including rope lights, strips, bulbs, pre-wired single LEDs, outdoor lights, sign displays, floodlights and spotlights. There are other types of LEDs as well used as indicators in electronic devices, in flashlights and as car lights. These lights also come handy while designing a motion sensing security system for home or office safety and protection against burglars.
LED traffic control system is also very popular across the globe. These small lights in different colors are made to operate continuously for directing traffic coming from different directions. Alerts and warning signs are also made by using these types of lights. Flashlights make use of LEDs because of their light weight and extremely powerful nature. They can last for many hours even if required for constant and steady operation. Most of these lights have 2 to 3 miles visibility and are therefore excellent to be used as danger alerts and warnings.
Semiconductor materials used in the making of LEDs include gallium phosphide, indium gallium nitride, diamond, zinc selenide, silicon, silicon carbide and some others. These lights do not contain mercury and are therefore useful for safe operations such as using around children and pets. Safety products such as LED safety flashers are very common all over the world. Emergency flares and other types of lights come under this category. LED lighting is also widely employed for interior design such as outdoor powerful lighting and under cabinet lighting. LED strips are often used for this purpose along with decorating the interior of cars and making an LED pet leash.
LED under car kits are also becoming increasingly popular in today’s fast-moving and modern world. These state-of-the-art lights are used to create an under-car lighting halo which looks beautiful from a distance. Many people who are fond of decorating their cars use these kinds of lights. Their specifications include display of 2.1 million colors, many levels of flash speed, music displays, water proof and shatter proof, and requirement of 12V DC power. It is a multi-functional kit which comes very handy for different purposes. The best thing about this device is that it not expensive at all and lasts for a long time to come.
LED lights can be used for so many exciting purposes and decorative uses that you simply cannot ignore their importance. The night reader lamps that make use of LED lights are also popular among people of all ages. Their height and angle can be adjusted accordingly and therefore can be used as table lamps and for reading in bed. LED bulbs are used for household uses ranging from kitchen lighting to simple yet attractive decoration. Strip and rope lights are available to be used for wedding and Christmas celebrations.
The uses of LED lighting are unlimited. This kind of lighting is not only powerful but also very cost-effective. Because of this reason, many manufacturers are now providing different types of LED lights for almost all kinds of uses. These include ambient and architectural lighting, medical and portable lights, 3mm and 5mm small LEDs for electrical experiments, and single, ready-to-use LEDs for installation on unconventional surfaces like rocks and in aquariums. In addition to these, many companies also provide popular LED accessories including transformers, dimmers, voltage doublers, motion sensors, voltage regulators, and installation accessories. All these equipment and devices come very handy for all kinds of lighting purposes.

Green Light Laser Treatment For Bph (Enlarged Prostate) And Sexual Dysfunction
Anurag Golash asked:
Erectile dysfunction is a well recognized complication of the standard treatment for Benign Prostatic Hyperplasia (BPH), or the enlarged prostate. Approximately 10 per cent of patients who have a TURP are left with erectile dysfunction as a result of the procedure.
This is a considerable risk for patients. Although the majority of patients I see with BPH are 65 and above, I do see a number of patients in their fifties. These patients often decide against surgery – even if it means they have to live with symptoms of BPH – because they do not want to risk a complication which would have a major impact on their lives.
Equally, for some patients in the older age group, erectile dysfunction is very important.
At The Prostate Laser Centre, we discuss risks and complications very thoroughly with patients before the procedure. In some cases, patients may be focused on dealing with the symptoms and less concerned about complications pre-operatively. But post-op, once the patient starts to recover, complications can become a major source of anxiety.
This is one reason why Green Light Laser treatment is such an important development. The Green Light Laser provides a high powered, safe and precise means of destroying surplus tissue by vaporising selected areas. By contrast, during TURP, surplus prostate tissue is burnt by electrical currents.
The nerves which control erections are located just at the side of the prostate. During TURP, erection problem can possibly happen due to these nerves being damaged from the heat of the electrical current. The current can be fairly indiscriminating in terms of the areas it targets.
The Green Light Laser is far more targeted. Even though it is so powerful that surplus tissue is immediately vaporised, it does not penetrate deep into the tissue. Hence it is believed that it minimizes the risks of erectile dysfunction. In my experience, I have not yet seen erection problems developing after green light laser therapy.
Although Green Light Laser treatment is a relatively new development in the UK, it is well established in America and parts of Europe. A total of 200,000 procedures have been undertaken worldwide. A major study* showed there is a 1 per cent rate of erectile dysfunction following Green Light Laser treatment, compared with 10 per cent for TURP.
A very common side effect after TURP is known as retrograde ejaculation. This means during orgasm, semen passes into the bladder rather than out through the penis. The semen is then voided the next time urine is passed. Retrograde ejaculation is not harmful and for many men it is not problematic, although it does result in less sexual satisfaction and infertility. The risk of retrograde ejaculation following TURP is high, up to 90 per cent. The figures for retrograde ejaculation following Green Light Laser are much lower, at between 29 and 41 per cent.
In conclusion, Green Light Laser offers patients the same result as TURP – rapid relief from the symptoms of BPH. However, with Green Light Laser, this is achieved with much reduced side-effects and complications. These benefits for the patient must be recognised.

How to Make an LED Light Up Bottle
Suie Roberts asked:
To make the LED light up bottle you will need…
A clear glass bottle, a meter or so of tinsel, a loo roll or kitchen towel tube, glitter, PVA glue, and a set of 20 LED lights. You can get these ready made from with a battery compartment from the ‘99p Store’ on your local high street. Tech confident people could make their own from individual components. DO NOT use mains fairy lights, this is a fire hazard!
First wash out the bottle and remove all the labels. Use a nice smelling detergent to rid the bottle of any lingering odours from its previous contents. Leave the bottle to drain and dry out completely.
Take the LED lights and the Tinsel, use a small amount of selotape and stick the wire directly behind the last LED bulb (the bulb furthest away from the battery compartment) to the end of the strip of tinsel.
Twist the string of lights and the tinsel loosely together and carefully push the lights and tinsel into the bottle until the battery compartment rests on the neck of the bottle.
The loo roll or kitchen towel tube will become a fancy bottle stopper that covers the battery compartment.
Draw around the end of the tube onto a piece of card. A grocery box is great. Cut the disc out and push it into the end of the tube. Use a bit of selotape to hold it in place.
Cover the tube and end piece in PVA glue and sprinkle with glitter. Cover the cardboard completely so that it is no longer visible. Leave to dry.
Perch the battery compartment on top of the bottle and place the glitter bottle stopper over the top of it, so that it hides the batteries and part of the neck of the bottle.

LED Lighting – Enlightening the World
pvyas asked:
Light Emitting Diode, which is conveniently called as LED lights in electronic term is a semi conductor light that emits light as soon as an electric current is applied to it. They are extensively used as indicator lights on electronic devices and also in higher power applications as in case of flashlights and area lighting. As per the technological methodology, an LED is a light source which can be infrared, visible or ultra violet. The color is determined by the composition and condition of the semi conducting material used. Discovered in the year 1907 by H.J Round, a British experimenter, earlier these bulbs were used as replacements for incandescent indicators only.
Methodology
The white color of the LED bulbs come from a narrow band blue that is emitted naturally by GaN LEDs. The yellow on the other hand is generated by a phosphor coating on the die which absorbs a proportion of the blue and converts it to yellow. These GaN die are able to produce operational wavelengths from green to ultraviolet by varying the relative amounts of indium and gallium during production. When electric applied in the forward direction of the device it results in a form of electro luminescence where incoherent and narrow-spectrum light is discharged from the p-n junction in a solid state material.
Advantages
LED technology has taken the world to a whooping stage of development as it is very useful in conservation of energy and pollution. Some of the important advantages of the bulb are -
1. LED lights are more efficient when compared to the conventional bulbs and tube lights. They produce more light per watt against an incandescent bulb and this facet makes it very useful when used in battery powered or energy-saving devices.
2. This technology has the capacity of emitting various colors of light without the use of colors filters that traditional lighting methods require, thus saving initial costs.
3. Due to their small size, they can be easily placed and they also light up very quickly and achieve full brightness in microseconds.
4. These LED light have a better cycling life as compare to incandescent bulbs and also radiate much less heat in the process of switching on and off.
5. They have a better life span around 35,000 to 50,000 hours of useful life and LEDs mostly fail by dimming over time, rather than the abrupt burn-out of incandescent bulbs as in comparison to incandescent lights.
6. These lights are shock resistant and the solid package of the LED can be designed to focus its light. The fact that they are non toxic (do not contain mercury) also favors the application of these bulbs.
Disadvantages
However, withstanding all the advantages, there are certain short comings faced by these LED lights as well. they are listed below -
1. As compared to incandescent bulbs the LEDs are much more expensive and its execution largely depends on the ambient temperature of the operating environment. They require adequate heat sinking in order to make it more durable.
2. These LEDs are also voltage sensitive and one needs to be vigilant as they involve series of resistors or current-regulated power supplies. As they work on the mechanism of area light source, it becomes difficult for them to operate in spherical light field.
3. Of recent it is being observed by the scientists that blue and cool white LEDs emit blue light hazard that is unsafe for eyes. The cool white LED lights should not be used for outdoor lighting near astronomical observatories. Together these lights have certain limitations that are termed as blue pollution.
Applications
LED lights are perhaps the most advanced technology that is taking its tool over the people all over the world. Their application is diverse and hence they can be divided in three distinct categories – Visual signal application where the lights transpires from the bulb to the human eyes directly, Illuminations where LED light is reflected from an object to give visual response and finally, technological approach that does not require the contact with human visual system as in case of light photosynthesis in plants.
Products and Evolution
In the past decade, LED technology has expanded its scope to almost every household in the world. From little red spots that tells one that the wi fi connection is on, to the excellent light source that we see in our rooms just by switching on a plug, applications of LED is ubiquitous. Production quality LEDs are now capable of efficiencies of around 70 lm/W, compared with 12 lm/W for incandescent light bulbs, and single die devices are producing over 100 lm.
Today one can find the implication of these LED lights in many areas. Be it the LCD screen of the computers or the latest version of the mobile phones, be it Ipods or safety and security hardware like LED enabled drainage system or Led micro lights for reading at nights, LED technology is vast and growing by leaps and bounds. The newest trend in the electronic market is the green influence that has not left the LED world bereft. The most recent launches in the LED market are theLight bulbs that can help one save up to 90% of electricity costs plus reduce the heat output and even more than this the bulbs claim to last up to 10 times longer than a standard light bulb or compact florescent. Some of the most advanced LED enabled products in the electronic world are -
LED enabled Faucet Lights – Install this in your homes to give a new look to the monotonous water taps. Available in red and blue they are heat sensitive and alarm the user by changing colors, as soon as the water temperature goes above 89 degrees centigrade.
LED Jellyfish Mood Lamps – These are unique desktop tank that plays trick with the eyes by displaying three jellyfish that swim, with the aid of the 6 bright colorful LEDS that are placed at the top of the tank.
Sony’s Walkman - Sony, the largest supplier of electronic goods has launched a new Walkman called NWZ-X1000 that features an OLED (Organic light emitting diode) touchscreen.
Light Emitting Diode, which is conveniently called as LED lights in electronic term is a semi conductor light that emits light as soon as an electric current is applied to it. They are extensively used as indicator lights on electronic devices and also in higher power applications as in case of flashlights and area lighting. As per the technological methodology, an LED is a light source which can be infrared, visible or ultra violet. The color is determined by the composition and condition of the semi conducting material used. Discovered in the year 1907 by H.J Round, a British experimenter, earlier these bulbs were used as replacements for incandescent indicators only.

Astronomy, Stargazingand Green Laser Pointers
Frank asked:
Green laser pointers and Astronomy
There is nothing more frustrating in astronomy that than unsuccessfully trying to identifying an object in the night sky to a companion by waving your arms, pointing fingers, describing and gestulating. An elegant, simple and very effective solution to this problem is to use green lasers pointers to point out objects in the sky.
Green laser pointers are high technology gadgets that are becoming more and more popular in astronomy. Not only are green laser pointers ideal for pointing out celestial objects, they are also very useful for aligning telescopes and for atrophotography.
Why green laser pointers
Green laser pointers are the preferred laser pointer color for astronomy because green is the most visible laser pointer color. The reason why green is more visible is the human eye is most sensitive to green light. The other reason is the effect of light in the earth’s atmosphere. Light is visible in the sky when the atmosphere scatters it and higher wavelengths are scattered more than higher wavelengths. Green is a medium wavelength so it scatters more and is more visible than longer wavelengths such as red.
Other applications
Using green laser pointers to point out celestial object to people next to you is not the only application for laser pointers in astronomy. A green laser pointer can also be mounted on a telescope using a bracket or by holding the laser by hand in the groove parallel to the telescopes optical axis. The green laser pointer beam clearly shows where the telescope is pointing and the object being viewed through the telescope.
A green laser pointer mounted on a telescope can also makes aligning the telescope to a celestial object much faster and easier.
How powerful should the laser pointer be?
Green laser pointers can range in power levels from 1mW all the way to 200mW so deciding which power level to use can be tricky. The points to consider when choosing the power level for an astronomy laser are
-The number of people star gazing with you. If it is just one person, a low power such as 5mW will be suitable. If you are stargazing with a large group of people who will not be standing next to you, the laser needs to be more visible so a high power level such as 100mW would be suitable.
-The level of ambient light. If you are stargazing at dawn/dusk, during a full moon or in built up areas where there is a lot of light pollution, a low powered beam such as 5mW would be harder to see. You would generally need at least 50mW or more in this kind of situation.
Higher powered laser pointers are not always better because any glare from them can easily ruin your night vision and can provide a distraction. Many stargazing nights have been ruined when people have been paying more attention to the new and exotic high power laser used to point out objects than the actual objects themselves.
Caution
Deliberately pointing a laser at aircraft is a very serious offence in every country so avoid star gazing near airports and do not use a laser when there is an aircraft in the section of the sky being viewed.
