5, environmental protection, the pollution element such as the most leaded, hydrargyrum, environment is not had any pollution, and the assembling parts of LED bulb is non- Chang Rongyi dismounts, and reclaims can be reclaimed by other people without producer.

6, without stroboscopic, pure DC operation, eliminate the visual fatigue that conventional light source stroboscopic causes；

7, wide-voltage range, global general-use LED is in 85V～264VAC full voltage range constant current, it is ensured that life-span and brightness Do not affected by voltage pulsation；

8, luminescence may be up to 80lm/w depending on dumping ratio, has multiple LED colour temperature optional, and color rendering index is high, and color rendering properties is good.

Owing to the electric filament lamp that LED is more traditional has above advantage, the daily families such as mobile phone, desk lamp, household electrical appliances are applied to it The electrically and mechanically every field such as production.

But, existing LED generally there is problems in that can only be by its switch of staff's Non-follow control, it is impossible to satisfy the need Lamp surrounding effectively detects, night street lamp be generally in normal bright state, add the most meaningless energy waste； Cannot control the work of street lamp according to actual environment light intensity condition intelligent around street lamp, intelligence degree is relatively low, is lost bigger. And traditional LED power there is also following defect: 1) use series resistance to carry out current limliting, the electric energy of resistance loss is relatively big, Cause bigger energy loss, and high-powered LED lamp cannot be applicable to；2) cannot effectively absorb surge voltage, LED bears The instantaneous voltage carrying two ends increases severely, and is easily burned；3) cannot effectively suppress high frequency voltage, the output of LED power is the most flat Suitable, LED load job insecurity and with damage.
