LED Downlights Light-emitting Principle
Sep 27, 2017

LED tube light is application of a new type of LED lighting light source on the basis of traditional tube light of the development of improved products, compared with traditional tube light has the following advantages: energy saving, low carbon, long life, good color rendering and fast response. LED tube light, a design more beautiful light, installation to keep building decoration of the overall unity and perfect, does not destroy the set of lamps and lanterns, light hidden inside the building decoration, light source is not exposed, no glare, the visual effect of soft and uniform.

LED lamp is a kind of lighting lamp embedded in the ceiling. LED lamp is a directional lighting fixture, only its opposite can be exposed to light, beam Angle belongs to the concentrated light, the light is more concentrated, bright and dark contrast is intense. More prominently illuminated objects, the level of the luminosity is higher, more foil a quiet environment atmosphere.

LED tube light is mainly by way of diodes lighting, life depends mainly on solid LED light source and drives the cooling part, 2012 LED tube lamp life has reached more than 80000 hours, with the development of LED technology research and widely used, has the basic drive and heat to attain the ideal state, compared with the ordinary halogen tube light, commercially available high quality LED tube lamp life reached more than 80000 hours.

Light-emitting principle

The terminal voltage of PN junction constitutes a potential barrier. When the voltage of positive bias voltage is added, the majority of the carriers in the p-zone and N regions are diffused to each other. Because the electron mobility rate is much larger than the hole migration rate, a large number of electrons will be distributed to the P area, which constitutes the injection of the minority carrier in P area. These electrons are compounded with the hole in the valence band, and the energy is released in the form of light energy. This is the principle of PN junction luminescence.

Product features

Led tube light features: keep building decoration of the overall unity and perfect, does not destroy the set of lamps and lanterns, light hidden inside building decoration, no leakage, no glare, the visual effect of soft and uniform.

Energy saving: the same brightness consumes a half of the ordinary energy saving lamp.

Environmental protection: free of harmful substances such as mercury and no pollution to the environment.

Economy: the cost of the lamp can be recouped a year and a half due to the reduced cost of electricity. A family can save tens of yuan a month.

Low carbon: saving electricity is equivalent to reducing carbon emissions.

Longevity: LED lamps have a lifespan of 100,000 hours, and an LED light can be used for up to 40 years based on six hours per day.

Product advantages

1. Energy saving: the energy consumption of white leds is only 1/10 of the incandescent bulb, and 2/5 of the energy-saving lamps, longevity: LED theory can last more than 100,000 hours, and the lighting of ordinary homes is a "once and for all".

2. Can work at high speed: the energy saving lamp can be blackened and quickly damaged if it is frequently started or shut off.

3. Solid state packaging: a type of cold light source. So it is easy to transport and install, can be installed in any micro and enclosed equipment, not afraid of vibration, the main consideration is heat dissipation.

4. The technology of LED lamps and lanterns is improving rapidly. Its luminous efficiency is making an amazing breakthrough and the price is decreasing continuously. An era of white LED lamps entering the family is rapidly approaching.

5. Environmental protection: harmful substances, such as mercury (Hg), do not cause damage to the environment. The assembly parts of LED lights can be removed very easily and can be recycled by other people without the manufacturer's recycling. LED does not contain infrared, uv, so it is not a bug.

6. Quick response: fast LED response, and eliminate the disadvantages of traditional high-pressure sodium lamp process.

Conclusion: it is obvious that the cost of LED lamps will decrease with the increasing of LED technology. Energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps. The country is attaching more and more importance to the energy conservation and environmental protection issues, and has been vigorously promoting the use of LED lamps. In particular, the government's transformation of street lamp projects is LED by LED street lamps, which indicates that LED lamps can be used to replace energy-saving lamps and incandescent lamps.
