[0006] A photoelectric integrated ceramic heat dissipation module, comprising a radiator, a circuit board, an LED lamp sheet, a capacitor, a transformer, driving electronic pieces and the like.

[0007] The radiator is of ceramic material, is disc-shaped, is provided with a plurality of vertically arranged heat dissipation fins at the bottom, is provided with mounting holes at the two sides, and the upper surface is a flat surface.

[0008] The circuit board is attached to the upper surface of the radiator, preferably, the circuit board is a sintered circuit, the sintered circuit is a technology of sintering material powder or fiber-like material into a circuit board, which sintering material into a uniform and dense board through high-temperature pressure, compression, time and other process links, so as to form a circuit board, compared with the traditional circuit board manufacturing method, the circuit sintering technology has the advantages of time saving, material saving, high precision, stable quality and the like.

[0009] The upper surface of the radiator serves as the substrate of the sintered circuit, that is, as the bottom plate of the circuit board.

[0010] The LED lamp sheet, the capacitor, the transformer and the shell of the driving electronics are attached to the upper surface of the heat sink and are electrically connected to the circuit board through pins.

[0011] The ceramic heat sink has the disadvantage of being fragile, especially when it is fixed to the lamp shell by fasteners, the heat sink is easily broken under pressure. Therefore, a mounting pressure relief gasket is arranged in the mounting hole of the heat sink, and when the mounting screw is screwed, the screw does not directly press the heat sink, and the screw gives pressure to the heat sink through the mounting pressure relief gasket, so that the heat sink is not broken.

[0012] The mounting pressure relief gasket comprises an upper guard ring piece, a lower guard ring piece and a connecting column; the upper guard ring piece and the lower guard ring piece are arranged oppositely and have the same structure; the upper end and the lower end of the connecting column are connected to the upper guard ring piece and the lower guard ring piece respectively.

The heat radiator 1 is easy to break under pressure. Therefore, the mounting hole 12 of the heat radiator 1 is provided with a mounting pressure-reducing rubber pad 6. When the mounting screw is screwed, the screw does not directly press the heat radiator 1. The screw gives pressure to the heat radiator 1 through the mounting pressure-reducing rubber pad 6, so as not to cause the heat radiator 1 to break.
