For the “veteran” of the lighting in the area of energy-saving lamps and New Horizons LED, there have been different “promotion and treatment” policy level. Policies promotion is very significant to promote market penetration for an industry, energy-saving lamps has received a four-year state subsidies. Last year, it has suffered the embarrassing problem of mercury contamination in the recovery. This year, LED lamps china are the first to gain state subsidies. Although some experts said, the meaning for subsidies “attitude” are more than the meaning of “reality”, but it seems that subsidies Deal “signal” bring them to the support and confidence for the enterprise.

Commercial nature

State support LED trend has emerged, on the other side, the energy-saving lamps continue to receive subsidies, while its proposed higher threshold. This will accelerate the traditional lighting companies to G24 LED in transition.

According to the website of the Ministry of Industry in November this year, in order to implement the State Council and the “energy saving” 12th Five-Year Plan “and” heavy metal pollution prevention “Twelfth Five-Year Plan” to reduce the mercury content of fluorescent products the preparation of the “LED lamps china gradually reduce the mercury content of fluorescent lamps roadmap draft. Production process phase out the liquid mercury; On December 31, 2014, to December 31, 2013, the fluorescent liquid mercury Production will be phased out totally.

“This is because a large number of energy-saving lamps subsidies started to enter the demise periods, while the recovery system is not perfect.

It is understood that, since 2008, there promotes 150 million energy-saving lamps within three years, 50 million a year; subsidies for energy-saving lamps, including the U-shaped lamps, T8 trichromatic lamp, T5 lamps, suitable for factories, schools, institutions residents, etc.

“In fact, due to the policy promotes, the popularity and sales of energy-saving lamps are far more than the quantity, the using range is more wider.” Zhang added.

Previously, Europe and the United States and other countries have asked the incandescent phase-out schedule. China execute green lighting project from 1996, the production of energy-saving lamps and incandescent already by 1:34 in 1996 to 1:1 in 2010, the global market share of energy-saving lamps increased from 20% in 1996 to 85% in 2010.

To take high-power white LED as a new green lighting, it will have many advantages such as light conversion, high efficiency, low power consumption, long life, no maintenance, etc. And thus it gradually used in a variety of lighting in the field. The long life of the LED is based in the safe working environment. As far as LED lamps china lighting is concerned, there are two factors affecting the life. One is the over electric shock which is applied to the LED on the current exceeding the maximum rated current of the LED technology in the date sheet, including over-voltage caused by over-current shock; Another is overheating damage. Damage can be expressed as the immediate failure of the components and it may also occur through electric shock after the incident for a long time before failure and to shorten the working life of LED.

LED lamps china causes of damage

LED lights failure first from the power supply and drive failure, the second is from the LED assembly failure. From the input power, it is usually damage to the LED power supply and drive through electric shock(EOS) and the load side of circuit failure.

LED components failure

  Transient over-current events is the maximum rated current flowing through the LED current in the LED lamps china technology data sheet, which may be the direct result of the large current or indirectly due to the high voltage generation, such as transient lightning switch over voltage event of power transient switching noise, power fluctuations caused by over current. These events are transient, very short duration. we usually referred to as spikes, such as “current spikes, voltage spikes. The transient over-current is caused by LED connected to the transient over-current power or hot plug.

LED lighting in the car, ISO7637-2 transient load-dump surge impact, it is a major threat to their normal work.
LEDs subjected to electric shock after the failure mode is not fixed, but will usually result in damage to the welding line. This damage is usually caused by a great deal of transient over-current, which will cause weld lines blown and may also lead to other parts of the damage near the welding line, such as sealing materials.
