Luminescence unit circuit board module

Abstract

The invention discloses a luminescence unit circuit board module which comprises a luminescence unit circuit board and a parallel-metal base. Each luminescence unit is provided with a substrate formed by stacking an upper metal insulating material and a lower metal, and the parallel metal base comprises a first metal board and a second metal board; the first metal board is electrically coupled to the upper metal and provided with a first metal pin, and the second metal board is electrically coupled to the lower metal and provided with a second metal pin; the circuit board comprises a first electric contact region and a second electric contact region, the first electric contact region is electrically coupled to the first metal pin, and the second electric contact region is electrically coupled to the second metal pin. The parallel-metal base of the luminescence unit circuit board module is spliced with the circuit board in a plug-in mode so as to be convenient to assembly, maintain and replace the product.

Description

technical field [0001] The invention relates to a light-emitting unit circuit board module, in particular to a light-emitting module provided with parallel metal seats for the light-emitting unit to be placed on the circuit board in a plug-in manner. Background technique [0002] Common lighting modules such as figure 1 As shown, the light-emitting unit 12 has a plane area where the light-emitting chip 10 is arranged on the first metal pin 141, and the metal pin 141 extends downward; the light-emitting chip 10 has a bottom surface electrode electrically coupled to the first metal pin 141; the light-emitting chip 10 has a surface electrode , electrically coupled to the second metal pin 142 by the metal line 13 . The circuit board 15 has a plated through hole 151 and the circuit 152 is connected to the power supply terminal. The first metal pin 141 and the second metal pin 142 are inserted into the corresponding plated through hole 151 on the circuit board 15, and then the fi...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned light-emitting module is not easy to assemble and not easy to maintain

During assembly, a welding procedure is required, and when the light-emitting unit 12 fails, when the light-emitting unit is to be replaced, the solder must be removed before replacement

And the plane of this common circuit board 15 is perpendicular to the optical axis of the light-emitting unit. When the periphery of the product needs to be reduced, for example, when it is to be placed in a traditional lamp holder to replace a traditional light bulb, the design of this circuit board 15 will not be able to be placed traditional lamp holder
