Description

Technical Field

[0001] The utility model relates to the technical field of automatic control, in particular to an ultra-thin power supply with adjustable light for LEDs. Background Art

[0002] As a lighting source, LED lamps offer numerous advantages, including fast response, excellent color rendering, high conversion efficiency, energy saving, long life, and low cost. Their applications are expanding, and they are gradually replacing traditional incandescent, fluorescent, and discharge lamps. Currently, LED power supplies used to drive LED lamps are very thick using traditional processes, significantly limiting their application in space-constrained installations. Therefore, an ultra-thin, dimmable LED power supply is needed to meet the needs of space-constrained applications.

[0003] Currently, an ultra-thin dimmable LED power supply (e.g., patent number CN207569822U) is available. All components are located on the same side of the power supply PCB. Components are installed on the PCB using surface-mount or plug-in methods. The pins of plug-in components do not extend above the component-free plane of the PCB. This utility model's technical solution allows for an ultra-thin dimmable LED power supply, expanding its application range. It also reduces process steps and labor costs, resulting in significant economic benefits.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems: although the existing device is designed to be ultra-thin as a whole, the high integration of various components will generate heat accumulation, resulting in serious heating of the entire device. However, the existing device is not provided with a heat dissipation structure, so the existing device has the problem of heat accumulation. Utility Model Content

[0007] (2) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0024] The embodiment of the present application provides a dimmable ultra-thin power supply for LEDs, which effectively solves the problem of heat accumulation during use of existing devices, resulting in high temperatures.

[0025] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the existing device accumulates heat during use, resulting in high temperature. The overall idea is as follows:

[0026] In response to the problems existing in the prior art, the present invention provides a dimmable ultra-thin power supply for LEDs, comprising a housing 1, a top shell 101 fixedly connected to the top surface of the housing 1, an electronic component group 2 arranged inside the housing 1, and heat dissipation mechanisms 3 provided at both ends of the inner wall of the housing 1, the heat dissipation mechanism 3 including a heat dissipation fan body 301, and the heat dissipation fan body 301 being electrically connected to the electronic component group 2.

[0027] A middle partition plate 103 is fixedly connected to the middle section of the housing 1 , and air outlet holes 102 are formed at both ends of the middle partition plate 103 of the housing 1 .

[0028] Two threaded holes 104 are formed at both ends of the inner wall of the housing 1 .

[0029] The cooling fan body 301 is placed as a whole at both ends of the inner wall of the outer shell 1. The two cooling fan bodies 301 cooperate with the top shell 101 to seal the opening of the outer shell 1. A dustproof net 302 is fixedly connected to the air inlet of the cooling fan body 301. The setting of the dustproof net 302 can prevent external dust from entering the interior of the outer shell 1, prevent dust from adhering to the electronic component group 2, affecting the operation of the electronic component group 2, and avoiding short circuit. The air outlet of the cooling fan body 301 is fixedly connected to a number of air guide plates 305.

[0030] Two grooves 303 are defined on one end of the heat dissipation fan body 301 away from the top shell 101 . A threaded through hole 304 is also defined on the heat dissipation fan body 301 at the position where the grooves 303 are defined.

[0031] The two threaded through holes 304 are aligned with the two threaded holes 104 . Micro bolts 4 are threadedly connected in the threaded through holes 304 and the threaded holes 104 . There are four micro bolts 4 in total. The micro bolts 4 are used to connect and fix the cooling fan body 301 to the housing 1 .

[0032] The present application is provided with a heat dissipation mechanism 3, which includes a heat dissipation fan body 301. When the device as a whole starts to work, the electronic component group 2 will start the heat dissipation fan body 301. The heat dissipation fan body 301 absorbs external air, and after the dust in the air is filtered by the dustproof net 302, the airflow is introduced into the interior of the shell 1 through the air guide plate 305 set at the air outlet. The airflow takes away the heat generated by the electronic component group 2 and is finally discharged from the air outlet 102 to achieve heat dissipation and cooling, so that the electronic component group 2 of the present application can be cooled quickly, avoiding the heat generated by the electronic component group 2 from accumulating inside the shell 1, solving the problem that the existing device accumulates heat during use, resulting in high temperature, and at the same time making the present application safer.

[0033] Working principle:

[0034] In the first step, when the entire device starts working, the electronic component group 2 will start the cooling fan body 301, the cooling fan body 301 will absorb the outside air, and after the dust in the air is filtered by the dustproof net 302, the airflow is introduced into the interior of the shell 1 through the air guide plate 305 set at the air outlet. The airflow takes away the heat generated by the electronic component group 2 and is finally discharged from the air outlet 102 to achieve heat dissipation and cooling.

[0035] In the second step, the two micro bolts 4 are removed to disconnect the heat dissipation mechanism 3 from the housing 1 , so that the heat dissipation mechanism 3 can be quickly disassembled, making it easier to repair and clean the heat dissipation fan body 301 .

[0036] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
