The second method known as Phosphor Converted LEDs

A Led light is a solid-state lamp that uses light-emitting diodes (LEDs) as the source of light. A single LED is a low-voltage device and cannot be directly operated on AC power without circuitry. They are generally made by following two processes. One is known as RGB (Trichromatic White Led), that uses multiple led chips, each emitting different wavelength, in close proximity to generate the broad spectrum of white light.

The second method known as Phosphor Converted LEDs (PCLEDs) that uses one short-wavelength led (usually blue, sometimes ultraviolet) in combination with a phosphor which absorbs a portion of the blue light and emits a broader spectrum of white light. Led lamps have no glass tubes to break and their internal parts are rigidly supported, making them resistant to vibration and impact. With proper driver electronics design, a led lamp can be made dimmable over a wide range; there is no minimum current needed to sustain lamp operation. Led bulbs, produce light by running an electric current between two electrodes.


led bulb are ideal for home use and commercial use. They can be used on down lights, kitchen lights, lamps, and garden lights. They can also be used in malls and even on traffic lights. Led bulbs can last for twenty-five thousand hours to eighty thousand hours. This helps to avoid frequent light replacements and save more money. Led bulbs are energy-efficient. One of the best advantages of led lights are that they are cool to touch and do not hurt even after several hours of use. These are used on hunting and camping trips, and can be used as emergencies and flashlights.

This reduces the heat loss, and can also save the power of the air conditioning, because the temperature in the whole room can be significantly reduced.Of course, the same also applies to the domestic home lighting. Down lights 50W halogen amazing popularity of store, came to the same environmental impact, the desire in our homes. Outdoor LED light bulbs can produce the same effect of reducing the electricity bill of 80% of electricity and a significant improvement of the quarter. In addition, the light from the LED spotlights clarity obvious than halogen.When upgrading to LED spotlights important information:Standard halogen spotlights, LED spotlights, a significant difference in 12V AC transformer AC 12V MR16 halogen spotlights run.

A LED spotlight prefers a 12v DC (direct current) transformer. This can cause compatibility issues if people are not aware of the difference. Keeping your existing fixture with a MR16 LED spotlight would require changing to an LED transformer if replacing MR16 halogen spotlights. In addition, you can replace the fixture, rather than a Jump Start. The reason you have to change the fixture is because all mains voltage metal light fixtures have to be earthed by law. MR16 12V connector is not grounded, because they are low voltage and by transformer isolation.www.progressive-hk.com was founded in 2007 as a professional manufacturer of LED Indoor & Outdoor Lighting Products.
