A new type of ceiling light with heat dissipation structure

Abstract

This utility model discloses a novel ceiling light with a heat dissipation structure, including a lamp panel, a light source plate fixed to the bottom surface of the lamp panel, and a light-transmitting lampshade. A recessed area is provided at the top edge of the lamp panel, and the side wall of the recessed area near the center is inclined. Several heat dissipation slots are formed at the bottom of the inclined surface. A vertical support plate is integrally formed on the bottom wall of the recessed area, and a heat-conducting groove with a closed top is formed on the side of the vertical support plate. The lower part of the vertical support plate is connected to the lower part of the inclined surface, and there is a gap between the upper part of the vertical support plate and the upper part of the inclined surface, with the upper part of the heat-conducting groove located within the gap. The heat dissipation slots are located at the bottom of the heat-conducting grooves. The heat dissipation grooves on the side of the vertical support plate, combined with the heat dissipation slots at the bottom of the inclined surface of the recessed area, effectively achieve heat conduction and dissipation. Heat dissipation is from the side of the heat-conducting grooves outwards, preventing dust and other contaminants from directly entering the lamp body through the heat dissipation slots, thus improving light leakage prevention performance and enhancing the effectiveness and stability of heat dissipation.

Description

Technical Field

[0001] This utility model belongs to the field of ceiling light technology, specifically relating to a ceiling light with a novel heat dissipation structure. Background Technology

[0002] Ceiling lights are a common type of lighting fixture. They generally consist of a lamp panel, a light source plate fixed to the bottom of the lamp panel, and a light-transmitting lampshade set on the bottom of the lamp panel. In order to improve heat dissipation performance, several heat dissipation slots are usually directly cut into the top panel, as shown in CN201621397658.1. Although this can meet the heat dissipation requirements, because the heat dissipation slots are directly set in the lamp panel, and the slots are a through structure, impurities can enter the lamp body through the heat dissipation slots, which can easily cause serious light leakage and affect the effectiveness of heat dissipation. Summary of the Invention

[0003] The purpose of this invention is to provide a ceiling light with a novel heat dissipation structure.

[0004] The technical solution to achieve the purpose of this utility model is a ceiling light with a novel heat dissipation structure, including a lamp panel, a light source plate fixed on the bottom surface of the lamp panel, and a light-transmitting lamp cover. A recessed area is provided at the edge of the top surface of the lamp panel, and the side wall of the recessed area near the center is an inclined surface.

[0005] The bottom of the inclined surface is provided with a number of heat dissipation slots, and a vertical support plate is integrally formed on the bottom wall of the recessed area. A heat conduction groove with a closed top is provided on the side of the vertical support plate.

[0006] The lower part of the vertical support plate is connected to the lower part of the inclined surface, and there is a gap between the upper part of the vertical support plate and the upper part of the inclined surface, with the upper part of the heat conduction groove located within the gap.

[0007] The heat dissipation slot holes are located at the bottom of the heat conduction slot;

[0008] The heat from the light source board is discharged outward through the gaps after passing through the heat dissipation slots and heat conduction slots.

[0009] A further preferred embodiment is that the center of the lamp panel has two integrally formed screw-hole posts;

[0010] The two ends of the mounting bracket are attached to the top surface of the screw hole post and fixed by screws.

[0011] A further preferred embodiment is that a driver box is fixed to the top surface of the lamp panel, and a cover is snapped onto the top surface of the driver box;

[0012] A wire through hole is provided between the lamp panel and the driver box.

[0013] A further preferred embodiment is that the height of the vertical support plate is less than or equal to the depth of the recessed area.

[0014] A further preferred embodiment is that the lamp panel is a square lamp panel, a round lamp panel, or an elliptical lamp panel.

[0015] Compared with the prior art, the present invention has the following positive effects: The present invention has a vertical support plate on the bottom wall of the recessed area, and the side of the vertical support plate has a heat conduction groove with a closed top. Combined with the heat dissipation groove hole at the bottom of the inclined surface of the recessed area, it can not only effectively conduct heat and dissipate heat, but also, since the top of the heat conduction groove is closed, the heat dissipation is from the side of the heat conduction groove to the outside. Therefore, dust and other objects cannot directly enter the lamp body from the heat dissipation groove hole, which can prevent light leakage from the heat dissipation groove hole, and also helps to improve the anti-light leakage performance, and helps to improve the effectiveness and stability of heat dissipation.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a novel ceiling light with a heat dissipation structure includes a lamp panel 1, a light source plate 2 fixed to the bottom surface of the lamp panel, and a light-transmitting lampshade 3. A recessed area 4 is provided at the top edge of the lamp panel, and the side wall of the recessed area near the center is an inclined surface 5. In this embodiment, the depth of the recessed area can be processed and set as needed, and the inclined surface is at an angle of 70-85 degrees to the horizontal plane, that is, the upper width of the recessed area is greater than the lower width of the recessed area. The lamp panel can be a square lamp panel, a round lamp panel, or an elliptical lamp panel.

[0024] Furthermore, the bottom of the inclined surface is provided with several heat dissipation slots 6, and a vertical support plate 7 is integrally formed on the bottom wall of the recessed area. A heat-conducting groove 8 with a closed top is formed on the side of the vertical support plate. During processing, the lower part of the vertical support plate is connected to the lower part of the inclined surface. In actual application, the lower part of the vertical support plate and the lower part of the inclined surface can be integrally formed, and there is a gap between the upper part of the vertical support plate and the upper part of the inclined surface. The upper part of the heat-conducting groove is located within the gap. The heat dissipation slots are located at the bottom of the heat-conducting grooves. The heat from the light source board is discharged outwards from the gap after passing through the heat dissipation slots and the heat-conducting grooves. Through the above structure, the heat inside the lamp panel is discharged from the side of the vertical support plate after passing through the heat dissipation slots and the heat-conducting grooves. This not only ensures effective heat dissipation performance but also prevents dust and other contaminants from entering the lamp panel through the heat dissipation slots and thus avoids clogging the heat dissipation slots.

[0025] Furthermore, the lamp panel has two integrally formed screw-hole posts 9 in the middle; the two ends of the mounting bracket 10 are respectively attached to the top surface of the screw-hole posts and fixed by screws. The mounting bracket is fixed to the ceiling or suspended ceiling with screws, and then the lamp panel is fixed to the mounting bracket.

[0026] Furthermore, a driver box 11 is fixed to the top surface of the lamp panel, and a cover 12 is snapped onto the top surface of the driver box; a wire through hole is provided between the lamp panel and the driver box. A driver circuit board, etc., can be fixed inside the driver box and can be directly connected to the light source board.

[0027] In this embodiment, the height of the vertical support plate is less than or equal to the depth of the recessed area. That is, the vertical support plate will not affect the normal installation operation of the lamp panel.

[0028] Compared with the prior art, the present invention has the following positive effects: The present invention has a vertical support plate on the bottom wall of the recessed area, and the side of the vertical support plate has a heat conduction groove with a closed top. Combined with the heat dissipation groove hole at the bottom of the inclined surface of the recessed area, it can not only effectively conduct heat and dissipate heat, but also, since the top of the heat conduction groove is closed, the heat dissipation is from the side of the heat conduction groove to the outside. Therefore, dust and other objects cannot directly enter the lamp body from the heat dissipation groove hole, which can prevent light leakage from the heat dissipation groove hole, and also helps to improve the anti-light leakage performance, and helps to improve the effectiveness and stability of heat dissipation.

[0029] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
