Semiconductor light source

Abstract

The present invention relates to a semiconductor light source using LED chip as light-emitting body. It is characterized by that single LED chip is sealed by using transparent epoxy resin, its exterior is coated with fluorescent powder so as to form light-emitting unit; several light-emitting units are parallelly-connected by means of conductor, and fixed and sealed on the conductive light-reflecting surface of light-reflecting body by using transparent epoxy resin. The positive electrode of LED chip is welded with the conductive light-reflecting surface, the negative electrode of said LED chip is connected with negative electrode of LED chip drive circuit output by means of wire, and the positive electrode of LED chip drive circuit output is connected with conductive light-reflecting surface of the light-emitting body by means of another wire so as to form an ultrahigh luminance line lamp. Said invention also can be made into various forms, and can adopt the LED chip capable of sending different color lights and correspondent fluorescent powder coating layers so as to form the light source capable of sending different colors.

Description

technical field [0001] The invention relates to an illumination light source, namely a semiconductor diode LED lamp. Background technique [0002] Semiconductor light-emitting diode (LED) is a cold light source device that can directly convert electrical energy into visible light and radiant energy. It has low operating voltage, low power consumption, high luminous efficiency, extremely short response time, shock resistance, vibration resistance, Stable and reliable performance, pure light and color, non-toxic, harmless, small size and other advantages. [0003] For a long time, due to the low light efficiency of LED, it is only used in display, indicator light, signal light, display screen, landscape lighting and other fields. However, the application in the field of lighting is not common and has yet to be developed. [0004] In recent years, with the continuous deepening of research on semiconductor light-emitting materials, the continuous progr...

AI Technical Summary

Problems solved by technology

[0006] First, the luminous flux is low, limited by the LED lighting angle, which cannot meet the needs of lighting;

[0007] The second is to use multiple LEDs in series and parallel, the circuit is complicated and the cost is high;

[0008] The third is that the LED heat dissipation is not good, which greatly reduces the service life
