LED light source of claim 1, leakage current LED is one-way conductive light, if there is reverse current is called leakage, the leakage current is large LED, short life, specializing in the production of Yangling box lights, low prices. 2, uses a different angle LED luminous light emitting angle is not the same. Special light-emitting angle, and higher prices. If all diffusion angle, and higher prices. 3, the key is the quality of life of different life, life is determined by the light fades. Light is small, long life, long life, high price. 4, chip LED luminous body for the chip, different chips, prices vary widely. Japan, the United States more expensive chips, lamp lights, generally made in Taiwan and chip prices lower than Japan, the United States. LED characteristic performance characteristics: 1, the fourth generation of green, high-power white LED solid state light source, high luminous efficiency, long service life of 100,000 hours, can achieve long-term maintenance; user-friendly product design, customers can choose different places to adapt the lighting operating voltage; low power consumption, power consumption is only 20% identical to the incandescent lamp luminous flux; 2, wide voltage design, easier to use; 3, LED anti-glare shade makes the light softer No glare, does not cause eye fatigue workers, improve work efficiency; good electromagnetic compatibility will not cause pollution to the power supply; 4, the housing is made of light alloy, corrosion resistant, waterproof and dustproof; 5. Transparency imported bullet-proof plastic material, high transparency, good impact resistance, can lights work in a variety of harsh environments; box lights, lighting Shenzhen far, far Yangling box lights Lighting Co., Ltd. is provided by Shenzhen. Box lights, Shenzhen far lighting, Yangling box light bar is far Lighting Co., Ltd., Shenzhen (www.zhenyuled.cn) (www.zhenyuanled.cn) this year introduced a new upgrade, the above picture is for reference only, please call this page or Tel picture on to obtain the latest information, contact: Li.
