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 adversely affect the rate at which the heat of the LED is conducted to the heat sink through the circuit board. Influence, which in turn makes it difficult to effectively improve the heat dissipation efficiency of the LED light source module

The invention relates to a light source module and a heat dissipation block. The light source module comprises the heat dissipation block, a light emitting diode crystal plate and a fan module. The heat dissipation block comprises a surface. The light emitting diode crystal plate is arranged on the surface of the heat dissipation block. The fan module and the light emitting diode crystal plate are respectively arranged at two opposite sides of the heat dissipation block. The fan module comprises an opening, a blade and a baffle plate surrounding the opening, wherein the blade is arranged in the opening and is suitable for generating air flow which flows along the flowing direction so as to carry out heat dissipation to the heat dissipation block, and the baffle plate is used for preventing the air flow from flowing along the direction which is opposite to the flowing direction. The light source module has better heat dissipation efficiency, and the heat dissipation block is suitable for supporting the light emitting diode crystal plate and is provided with a plurality of exhaust holes, thereby adding the whole heat dissipation capability and improving the reliability of welding simultaneously.
Description
Technical field [0001] The invention relates to a light source module and a heat dissipation element, in particular to a light source module and a heat dissipation block using a light emitting diode chip as the 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 in 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...
