Description

technical field

[0001] The invention relates to an LED light bulb, in particular to a distributed heat dissipation LED light bulb, which belongs to the technical field of semiconductor lighting. Background technique

[0002] As far as the applicant knows, the core technology of semiconductor lighting lies in its luminous efficiency and heat dissipation structure. At present, the existing LED bulbs often use figure 1 In the integrated heat dissipation structure shown, a plurality of LED chips are fixed on the heat conductor through thermal conductive glue, and then the heat conductor is fixed on the heat dissipation lamp housing of the overall structure. When the LED power is increased and the heat dissipation effect needs to be improved, it must be achieved by increasing the volume of the lamp housing and the heat dissipation surface area. As a result, not only the weight and cost of the lamp are increased, but also often limited by the installation structure of the lamp. ...

Embodiment 1

[0016] The distributed heat dissipation LED light bulb of this embodiment is such as figure 2 , 3 , 4, it has a conductive lamp base socket 1, a lamp housing 3 approximately in the shape of a truncated cone, and an LED chip 10 that is housed in a hemispherical lampshade 7 and electrically connected to the conductive lamp base. The upper end of the lamp housing 3 is fixedly connected to the lamp socket 1 through the insulating bracket 2 , and the disc-shaped heat-conducting insulating plate 4 made of heat-conducting ceramic material is arranged at the lower end, and is fastened and connected with the lampshade 7 . The outer circle of the lamp housing 3 has cooling windows extending axially at intervals, forming a fence shape. There is a group of radial radial slots 4-1 on the heat conduction insulating plate 4 (see Figure 4 ), metal heat dissipation blades 5 with one end protruding into the lamp housing 3 are respectively inserted in each radial slot. The heat dissipation ...
