Description

Technical Field

[0001] This utility model belongs to the field of flat panel light technology, and specifically relates to a heat dissipation type flat panel light. Background Technology

[0002] Flat panel lights are a common type of lighting and decorative lamp structure. A typical flat panel light consists of a back cover and a panel, with a light source plate fixed between the back cover and the panel. Conventional flat panel lights mainly rely on the chassis for heat dissipation, which has relatively limited heat dissipation performance. To improve heat dissipation performance, Chinese patent 202323295398.X added a cooling fan and bracket to the top surface of the back cover. Although this can improve heat dissipation performance, since flat panels are mostly directly installed on ceilings or walls, adding a bracket increases the overall size and affects the overall height after assembly. It also affects the effectiveness of heat dissipation, thus limiting its applicability and making it difficult to meet market demands. Utility Model Content

A horn-shaped air guide pipe is provided at the air outlet of the heat dissipation fan, and one end of the S-shaped heat dissipation pipe is connected to the small diameter end of the horn-shaped air guide pipe through a conduit.

[0007] A further preferred embodiment is that the S-shaped heat dissipation pipe is a copper pipe or an aluminum pipe.

[0008] A further preferred embodiment is that the bottom surface of the rear cover is provided with an arc-shaped clearance groove;

[0009] The S-shaped heat dissipation pipe is located within the arc-shaped relief groove and is fixed with adhesive.

[0010] The light source board is fixed to the back cover with screws, and the S-shaped heat dissipation pipe is limited by the arc-shaped clearance groove and the light source board.

[0011] A further preferred embodiment is that the height of the arc-shaped relief groove is less than the diameter of the S-shaped heat dissipation pipe.

[0012] A further preferred embodiment is that the back cover is fixed to the panel by screws or clips.

[0013] A further preferred embodiment is that the diameter of the heat dissipation air inlet is 5-10cm, and the size of the heat dissipation fan is matched with the size of the heat dissipation air inlet.

[0014] A further preferred embodiment is that the inner diameter of the S-shaped heat sink is 2-5cm, and the wall thickness of the S-shaped heat sink is 1-5mm.

[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.

[0023] Example

[0024] See Figures 1 to 3 As shown, a heat dissipation type flat panel lamp includes a back cover 1 and a panel 2 fixedly connected. A light source plate 3 is provided on the side of the back cover near the panel. In this embodiment, the above structure is a conventional structure of the prior art, so it is not described in detail. The back cover and the panel are fixed by screws or clips.

[0025] In this embodiment, an S-shaped heat dissipation pipe 4 is fixed to the side of the back cover near the panel, and the light source plate is attached to the side of the S-shaped heat dissipation pipe away from the back cover. In this embodiment, the inner diameter of the S-shaped heat dissipation pipe is 2-5cm, and the wall thickness of the S-shaped heat dissipation pipe is 1-5mm. This does not significantly increase the overall thickness of the flat panel light, and the S-shaped heat dissipation pipe is made of copper or aluminum. This facilitates the rapid absorption and dissipation of heat from the light source plate. An exhaust hole 5 is fixed to the side wall of the back cover, and one end of the S-shaped heat dissipation pipe is connected to the exhaust hole. A heat dissipation air inlet 6 is fixed to the edge of the panel, and a cooling fan 7 is fixed to the heat dissipation air inlet 6. A horn-shaped air guide duct 8 is provided at the air outlet of the cooling fan, and one end of the S-shaped heat dissipation pipe is connected to the small-diameter end of the horn-shaped air guide duct through a conduit 11. In practical applications, to avoid the cooling fan interfering with the normal lighting of the panel, a small diffuser fan is used. Specifically, the diameter of the cooling air inlet is 5-10cm, and the size of the cooling fan is matched to the size of the cooling air inlet. To guide the airflow from the cooling fan into the S-shaped heat dissipation pipe, a trumpet-shaped air guide is used to ensure the effectiveness and stability of the cooling process. A dust filter is installed at the cooling air inlet, and the color of the dust filter matches the shape of the panel.

[0026] In this embodiment, the bottom surface of the rear cover is provided with an arc-shaped clearance groove 9; the S-shaped heat dissipation pipe is located in the arc-shaped clearance groove and fixed with adhesive; the light source board is fixed to the rear cover with screws, and the S-shaped heat dissipation pipe is clamped and limited by the arc-shaped clearance groove and the light source board. By setting the arc-shaped clearance groove, the space occupied by the S-shaped heat dissipation pipe can be reduced, and it is also beneficial for assembly positioning.

[0027] In this embodiment, the height of the arc-shaped relief groove is less than the diameter of the S-shaped heat sink. A driving power supply 10 is disposed inside the rear cover, and the driving power supply is connected to the light source board and the cooling fan. The driving power supply is a conventional structure of the prior art, simply applied in a basic manner.

[0028] This utility model has positive effects: The structure of this utility model is reasonable. It has an S-shaped heat dissipation pipe between the back cover and the light source board. Together with the heat dissipation fan on the panel, it can effectively improve the heat dissipation performance without affecting the overall appearance and aesthetics. It also does not increase the overall thickness of the flat panel light, nor does it affect the installation and use of the flat panel light. It can meet the needs of different situations and has strong applicability.

[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.
