Basic Profile Edit this paragraph LED is the English light emitting diode (LED) acronym, and its basic structure is an electroluminescent semiconductor materials, placed on a wire rack, then sealed with epoxy resin around, play Protective effects of internal wires, so the seismic performance of the LED. Main features editor at both ends of this section have a filament lamp, within the lamp filled with traces of argon and mercury vapor thin, coated with a phosphor tube wall full color led display, gas conductive filament between two time emit ultraviolet light, so a soft phosphor visible. Fluorescent work characteristics: when the lamp starts lighting requires a high voltage, not only allows normal light emitting current through, then the voltage across the lamp is lower than the supply voltage. Currently, LED lamp and general fluorescent contrast, the advantages are as follows: 1 led flashlight, energy saving. 2, long life. 3, the applicability of good, because of the small volume of a single LED, can be made into any shape. 4, the response time is short, is ns (nanosecond) level of response time, while ordinary lamp is ms (millisecond) response time levels. 5, environmental protection, non-hazardous metal waste recycling easy. 6, colorful, luminous color pure, narrow spectral range led, and can be red, green and blue color blending into a colorful or white. Disadvantages: 1, expensive. 2, the current efficiency can generally be done in the light and there is a big gap between the theoretical optical efficiency. 3 led chip, currently able to do life and theory of life (10w hours) there is a big gap. 4, there are still some heat. 5, the light fades can also be greatly reduced. However, these shortcomings can be overcome by improving the process, so even if the current LED light source can not completely replace the existing traditional light sources, but with the development of technology, the future of the world must be LED. led chip, wujiaqu led, lighting provided by Wuhan Pep Pep Lighting Limited.
