LED is the English light emitting diode (light emitting diode) acronym, and its basic structure is an electroluminescent semiconductor materials, placed on a wire rack, then sealed with epoxy resin around, protect the internal core wire effect, so the seismic performance of the LED. Currently, LED fluorescent and ordinary fluorescent contrast is a merit saving. 2, long life. 3, the applicability of good, because the volume of single LED is small, can be made into any shape. 4, the response time is short, is ns (nanosecond) level of response time, and general lighting is ms (millisecond) response time level. 5, environmental protection, non-hazardous metal waste is easy recovery. 6, colorful, luminous color pure, narrow spectral range, and by mixing three primary colors red, green and blue as colorful or white. Disadvantages 1, the price is expensive. 2, there can be universal light efficiency and light efficiency theory there is a big gap. 3, the current life and can do theoretical life (10w hours) there is a big gap. 4, or a certain amount of heat. 5, the light fades can also be significantly reduced. However, these shortcomings can be overcome through improved technology, so even if the current LED light source can not completely replace the existing conventional sources, but with the technology of the future must be dominated by LED LED lights, LED light emitted .LED lighting, led spotlight High power 60W 80W 120W 160W 180W LED decorative lights LED lights LED lights LED mining lamp LED lighting LED stage lights.
