As the further design to the aforementioned techniques scheme: aforesaid LED is directly fixed on the LED wiring board, the complete sealed volume of light-passing board.Light-passing board complete closed cavity volume has stoped dust, water lamp to penetrate in the cavity volume of heat radiation lamp socket effectively.The structure of this light-passing board also can for: aforesaid LED is connected with the LED wiring board with lead, and described light-passing board is provided with the through hole of corresponding matching one by one with each LED, and each through hole and each LED cooperatively interact and tighten LED; The top end surface of described each LED top and light-passing board maintains an equal level.When the LED of this structure is luminous, saved this barrier film of photic zone, luminosity is higher; Simultaneously, the through hole of this light-passing board and LED good fit also can stop material such as dust to enter in the heat radiation lamp socket.
As the further design to the aforementioned techniques scheme: the sidepiece of aforesaid heat radiation lamp socket is evenly distributed with the groove that passes the heat radiation lamp socket, and each groove is that axial line is provided with circular array with the vertical axis of heat radiation lamp socket.Groove can increase the gas permeability of heat radiation lamp socket, and its structure and acting on as cellular heat radiation lamp socket can improve the radiating rate and the radiating efficiency of the heat radiation lamp socket of ceramic material.Certainly, heat radiation lamp socket of the present utility model also can adopt modes such as establishing fin in heat radiation lamp socket outside to dispel the heat.
As the further design again to the aforementioned techniques scheme: the top of aforesaid heat radiation lamp socket is provided with the step-like groove that cooperates with the light-passing board specification, and light-passing board is fixed in the step-like groove of the lamp socket that dispels the heat by three screws.It is fair with the end face of heat radiation lamp socket that step-like groove and the light-passing board of heat radiation lamp socket cooperates order to make light-passing board be installed on the heat radiation lamp socket back well; In addition, make light-passing board and heat radiation lamp socket fixing seal by three screws.The two binding energy is strengthened functions such as the matching performance of light-passing board and heat radiation lamp socket and dustproof, waterproof.
In addition, heat radiation lamp socket cavity volume bottom two sides respectively are provided with first screw, and the insulation holder is provided with second screw of corresponding first screw; One screw bolt passes LED wiring board, first screw, second screw make LED wiring board, heat radiation lamp socket, insulation holder closely fix.Adopt bolt just can be directly heat radiation lamp socket and LED wiring board, insulation fixedly to be done and combine closely fixingly, simple direct, and installation is also very convenient.
In sum, LED light fixture of the present utility model is compared with the LED light fixture of prior art, the utlity model has following advantage:
1, because the heat radiation lamp socket adopts the Ceramic Composite heat sink material made with the insulation holder, has good insulation and high voltage performance, guarantee the quick heat radiating and the luminosity of LED light fixture, guaranteed the Insulation Problems of LED light fixture simultaneously.
2, the LED wiring board is close to the intracavity bottom of the lamp socket that dispels the heat, can faster, more effective quick heat radiating.
3, adopt simple screw, bolt etc. to be connected and fixed device, also do not influence the attractive in appearance of LED light fixture profile the time easy for installation.
