Problems solved by technology

The disadvantage of this method is that the cost of using metal circuit boards is high, and even if the power LED itself achieves thermoelectric separation, it still cannot achieve thermoelectric separation at the application system level, and the two will affect each other during work.
[0003] In addition, in current lighting applications, there are various requirements for the brightness and color of the light source. Now, in order to meet these requirements, each light source needs to be designed and manufactured separately. In fact, the difference between each light source is only the wiring. difference, it will not only spend a lot of time on the design and manufacture of circuit boards, but also lead to low production efficiency of light sources

Description

technical field [0001] The invention relates to an illumination light source, in particular to a power light emitting diode light source module. Background technique [0002] With the improvement of the luminous efficiency of light-emitting diodes and the improvement of the luminous flux of a single light-emitting diode, the application of light-emitting diodes in lighting is becoming more and more extensive. Since the temperature of the PN junction of the light-emitting diode is directly related to the light extraction efficiency and reliability of the device, in lighting applications, the heat dissipation of the light source of the light-emitting diode becomes one of the key factors affecting the performance and reliability of the light source. In the prior art, many use such as figure 1 The structure shown includes a power light emitting diode 1 and a metal circuit board 2 , and the power light emitting diode 1 is surface mounted on the metal circuit board 2 . Using met...
