Problems solved by technology

However, since there is generally an insulating layer on the circuit board to insulate different circuit layers, but the insulating layer is a poor conductor of heat, this will cause adverse effects on the rate at which the heat of the LED is conducted to the heat sink via the circuit board. Influence, which in turn makes it difficult to effectively improve the heat dissipation efficiency of the LED light source module

Description

Technical field [0001] The invention relates to a light source module, and in particular to a light source module using a light emitting diode chip as a light emitting element. Background technique [0002] With the advancement of semiconductor technology, today's light emitting diodes (LEDs) can emit high-brightness light and have the advantages of power saving, small size, and low-voltage driving. Therefore, light emitting diodes have been widely used Various lighting equipment. [0003] Generally speaking, when a light emitting diode emits high-brightness light, a large amount of heat energy is generated. If the heat energy cannot escape and is continuously accumulated in the light emitting diode, the temperature of the light emitting diode will continue to rise. As a result, the light-emitting diode may be overheated, which may cause brightness degradation and shortened service life, and in severe cases, it may even cause permanent damage. Therefore, current lighting equipme...
