Embodiment Construction
[0020] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0021] see Figure 1 to Figure 5 , The present invention provides a heat dissipation structure of a reflector, which includes a reflector 1 , a fan assembly 2 , a temperature controller 3 , a light source 4 and a lamp cap suspension assembly 5 .
[0022] Reflector 1, described reflector 1 comprises reflector body 11 and connecting portion 12, the center of described reflector body 11 has first through hole, and described connecting portion is cylindrical, and it is formed by described reflector The peripheral edge of the first through hole of the body extends upwards. In this embodiment, the cross-section of the reflector 1 is circular, and the diameter of the reflector 1 increases continuously from the side close to the connecting portion 12 to the other side a...

The invention relates to a light reflection cover heat dissipation structure. The light reflection cover heat dissipation structure comprises a light reflection cover, a fan component and a temperature controller, wherein the light reflection cover comprises a light reflection cover body and a connecting part, a first through hole is formed in the center of the light reflection cover body, and the connecting part is cylindrical and is formed by upwards extending from the peripheral edge of the first through hole of the light reflection cover body; the fan component is annular, a second through hole is formed in the center of the fan component, the fan component sleeves the connecting part through the second through hole, and air is discharged from the bottom side of the fan component; the temperature controller is fixed on the light reflection cover and electrically connected with the fan component, the temperature controller is used for detecting the temperature of the light reflection cover, when the temperature exceeds a first preset value, the fan component is started to operate, and when the temperature is lower than a second preset value, the operation of the fan component is stopped. According to the light reflection cover heat dissipation structure provided by the invention, the starting and the closing of the fan component are controlled by sensing the temperature of the light reflection cover through the temperature controller, so that the fan component can blow the air to the light reflection cover for heat dissipation, the arrangement of the complex heat dissipation structure is avoided, and the whole light reflection cover heat dissipation structure is small in volume, light in weight and smaller in required mounting space.
Description
technical field [0001] The invention relates to a lighting fixture, in particular to a heat dissipation structure of a reflector and a lighting fixture. Background technique [0002] Existing lamp reflectors generally do not have air convection cooling structures. In order to increase the heat dissipation effect in the prior art, the method of increasing heat dissipation fins and thus increasing the heat dissipation area to realize the heat dissipation of the lampshade is basically adopted, but the disadvantage of this method in the prior art is that the shape of the lampshade requires It is relatively large, heavy, high in cost, and requires a large installation space. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the prior art, and propose a reflector cooling structure and lamp, which are small in size, light in weight and require less installation space. [0004] In ord...
