Detailed ways

Below in conjunction with accompanying drawing, the utility model is further elaborated.

Referring to Figures 1-3, one embodiment of the present invention is a convective heat dissipation floodlight surface. The structure of the floodlight is similar to that of similar floodlights. The front part of the housing 1 is equipped with a cover 2, so that the inside of the lamp housing 1 forms a cavity, so that the lamp body board 4 is arranged inside the lamp housing 1, and the lamp body board 4 is installed in front of the electrical cover 5. part, the electrical board 5 has a terminal, and is also placed inside the aforementioned lamp housing 1, and more importantly, a radiator 6 needs to be installed around the outside of the lamp body board 4, and the radiator 6 is ring-shaped , and make the interior of the radiator 6 form a closed space with the surface cover 2 and the electrical cover 5, so that the lamp body plate 4 is placed in the closed space; more importantly, at least two convective devices need to be added on the lamp housing 1. Convection channels are formed between these convection holes 7, and the cooling fins on the outside of the radiator 6 are placed in the convection channels, so that the air flowing in the convection channels can prevent external dust and fine garbage from entering the radiator. If things go on like this, an adhesion layer will be formed, which will affect the heat dissipation effect of the radiator. It is preferred here that the aforementioned two convection holes 7 are preferably arranged at positions symmetrical to each other on the side of the lamp housing 1, so as to form a straight line of convection channels to facilitate air flow. For the unidirectional heat dissipation through hole, the convection channel can prevent external dust and fine garbage from accumulating on the fins of the radiator, and the air flowing in the convection channel can further improve the heat dissipation effect of the radiator 6 .

Preferably, in order to facilitate the adjustment of the irradiation angle of the floodlight, a handle 8 can also be installed on both sides of the above-mentioned lamp housing 1, the handle 8 is used to drive the floodlight to rotate on the bracket, and then present different irradiation angles . On the other hand, in order to facilitate the packaging of the lamp body plate 4 and the LED lamp bead on its upper part in the floodlight, a lens 9 and a glass cover 10 can also be installed on the upper part of the lamp body plate 4, and then the surface cover 2 and the glass cover A diffuser plate 11 is installed between 10, and then a shading cover 12 is installed on the face cover 2. A pressure ring 14 may also be provided between the diffuser plate 11 and the cover 2 , and a first sealing ring 13 may be added between the cover 2 and the shading cover 12 . Further, similar to the structure of similar floodlights, a sealing plate 15 can also be added between the aforementioned electrical appliance cover 5 and the lamp body plate 4 .

In this embodiment, by adding convection holes 7 on the lamp housing 1 and forming convection channels between the convection holes 7, when the heat dissipation fins of the radiator 6 are placed in the convection channels, dust or fine particles can be reduced.
