The internal characteristics of LED has determined that it is that optimal light source removes to replace traditional light source, and it has purposes widely.LED has following characteristics:
One, the little LED of volume is that a very little wafer is encapsulated in epoxy resin the inside basically, thus its very little, very light.
Two, the low LED power consumption of power consumption is quite low, and in general the operating voltage of LED is 2-3.6V.Operating current is 0.02-0.03A.In other words: the electric energy that it consumes is no more than 0.1W.
Three, long service life is under appropriate electric current and voltage, and can reach 100,000 hours the service life of LED.
Four, high brightness, LED low in calories use the chemiluminescence technology, and caloric value is more much lower than ordinary luminaire.
Five, environmental protection LED is made by nontoxic material, and containing mercury unlike fluorescent lamp can pollute, and LED also can recycling simultaneously.
Six, sturdy and durable LED is encapsulated in the epoxy resin the inside completely, and it is all firmer than bulb and fluorescent tube.Also do not have loosening part in the lamp body, it is non-damageable that these characteristics make that LED can be described as.
Existing LED fitting structure is more, and structure is comparatively complicated, the unfavorable technological deficiency of radiating effect but ubiquity.
