Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 to 3, the present embodiment provides a lamp, which includes a mounting board 1, an annular board 2, a light shielding board 3 and a plurality of LED lamps 4; the up end of annular plate 2 is connected with mounting panel 1, and the lower terminal surface of annular plate 2 is connected with light screen 3, and a plurality of LED lamps 4 are at the circumferential equipartition of annular plate 2.

According to the technical scheme, the LED lamps 4 are arranged on the periphery of the annular plate 2, so that light rays of the LED lamps 4 are emitted along the radial direction of the annular plate 2, and the illumination of the whole space is ensured; meanwhile, the design of the light screen 3 avoids the LED lamp 4 from generating inappropriate brightness distribution in the visual field of human eyes, and avoids the generation of glare, thereby avoiding the light injury of people to human eyes due to the glare.

The mounting plate 1 is provided with a heat dissipation device 5, and the heat dissipation device 5 is positioned in the annular plate 2; the heat dissipation device 5 comprises a turbine heat dissipation fan 51, an inner ring plate 52 and an intermediate ring plate 53, wherein the inner ring plate 52 and the intermediate ring plate 53 are installed on the installation plate 1, and the inner ring plate 52, the intermediate ring plate 53 and the annular plate 2 are sequentially arranged from inside to outside on the installation plate 1 and are concentric with the center axis; the turbine cooling fan 51 is mounted on the mounting plate 1 and located in the inner ring plate 52, the inner ring plate 52 is provided with an air inlet 521, an air outlet of the turbine cooling fan 51 is connected with the air inlet 521 of the inner ring plate 52, and the middle ring plate 53 is provided with a plurality of transition air outlets 531. The air flow is sent between the inner ring plate 52 and the intermediate ring plate 53 by the turbo radiator fan 51, and is sent out from the transition air outlet 531 of the intermediate ring plate 53, thereby performing air cooling and heat dissipation on the annular plate 2.

One end of the air inlet 521 of the inner ring plate 52 is provided with an outer convex arc-shaped air guide plate 522, and one end of the outer convex arc-shaped air guide plate 522, far away from the inner ring plate, is arranged at a distance from the inner wall of the middle ring plate 53, so that the air between the inner ring plate 52 and the middle ring plate 53 flows clockwise or anticlockwise; and a negative ion generator 6 is arranged between the inner ring plate 52 and the middle ring plate 53, and the negative ion generator 6 is positioned at one end of the far inner ring plate close to the convex arc air guide plate. The air sent by the turbo cooling fan 51 is sent to the negative ion generator 6 under the action of the convex arc-shaped air guide plate 522, so that a large amount of negative ions are carried by the air flow between the inner ring plate 52 and the middle ring plate 53 and are sent to the room after air cooling and heat dissipation are performed on the ring plate 2. In addition, the far inner ring plate end of the outer convex arc-shaped air guide plate 522 is arranged at a distance from the inner wall of the middle ring plate 53, so that the air flow between the inner ring plate 52 and the middle ring plate 53 can circulate, and the air flow which does not flow for a long time between the inner ring plate 52 and the middle ring plate 53 is avoided.

The plurality of transition air outlets 531 are uniformly distributed on the middle ring plate 53 between the convex part of the convex arc-shaped air guide plate 522 and the negative ion generator 6, so that the condition that air flow sent by the turbine cooling fan 51 directly passes through the transition air outlets 531 without passing through the negative ion generator 6 is avoided; the transition air outlets 531 are arranged in a clockwise inclined manner or an anticlockwise inclined manner, an arc-shaped guide plate 532 is arranged at the air outlet of each transition air outlet 531, and the arc-shaped guide plate 532 is convex. The transition air outlets 531 are obliquely arranged, so that the air flow between the middle ring plate 53 and the ring plate 2 flows and circulates clockwise or anticlockwise, and the heat dissipation effect on the ring plate 2 is improved; meanwhile, the matched design of the arc-shaped guide plate 532 prevents part of the air flow from flowing due to being in the area close to the middle ring plate 53 for a long time, and ensures that the air flow between the middle ring plate 53 and the ring plate 2 normally flows in a clockwise or anticlockwise circulating manner.

In addition, the annular plate 2 between two adjacent LED lamps 4 is provided with a heat dissipation opening 21, so that air flow carrying negative ions after heat dissipation enters the indoor space from the heat dissipation opening 21. At least one heat dissipation plate 22 is provided in the heat dissipation opening 21. The design of the heat dissipation ports 21 and the heat dissipation plates 22 improves the heat dissipation efficiency of the air flow to the annular plate 2.
