Description

Technical Field

[0001] This utility model relates to the field of LED downlight technology, specifically to an LED downlight with heat dissipation and dust removal capabilities. Background Technology

[0002] A downlight is a type of lighting fixture that is embedded in the ceiling and emits light downwards; it can be equipped with an LED light source.

[0003] For example, the public document with application number 202321609227.7 discloses an LED downlight capable of heat dissipation and dust removal. This utility model achieves heat dissipation and dust removal of the downlight through the same power source. The air duct layout is reliable, the heat dissipation efficiency is high, the dust removal effect is good, the brightness of the downlight application is guaranteed, and the service life of the downlight is extended. However, this LED downlight only relies on the airflow to blow away the dust. When the downlight is working, the lamp core receives electrical energy and generates a certain amount of static electricity. In addition, the material of the lamp core shell is easy to attract dust, which makes it impossible to completely blow away the dust by air force, resulting in poor cleaning quality.

[0004] Therefore, in view of this, we have studied and improved the existing structure to propose a heat dissipation and dust removal LED downlight. Utility Model Content

[0005] The purpose of this invention is to provide an LED downlight that can dissipate heat and remove dust, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat-dissipating and dust-removing LED downlight, comprising a housing, an inner wall of the housing having a cavity, a silent fan fixedly installed on the upper end of the inner surface of the cavity, a dust collection screen fixedly installed on the inner surface of the housing, and the same dust removal mechanism being provided inside the cavity and the inner wall of the inner circular surface of the housing.

[0007] Preferably, the dust removal mechanism includes a movable cylinder rotatably mounted on the inner wall of the inner circular surface of the housing, and the outer circular surface of the movable cylinder protrudes into the cavity.

[0008] Preferably, the dust removal mechanism further includes a brush fixedly disposed on the inner surface of the movable cylinder, the brush being attached to the surface of the dust collection mesh.

[0009] Preferably, the dust removal mechanism further includes a crossbeam fixedly installed on the upper end of one side of the movable cylinder inside the cavity, and a turbo fan is fixedly installed on the upper surface of the crossbeam, with the turbo fan and the silent fan being vertically opposite each other.

[0010] Preferably, the surface of the movable cylinder is provided with a ventilation opening, which connects the cavity to the interior of the shell.

[0011] Preferably, a circuit board is fixedly disposed on the top of the inner surface of the housing, and an LED bulb is installed on the lower surface of the circuit board by means of a threaded connection.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the setting of a silent fan and a vent, allows the silent fan to draw in fresh air from the outside and blow it onto the circuit board to cool it down. The fresh air flow also carries away the heat generated inside the device and blows it out through the vent from the cavity to the outside, effectively cooling the entire downlight. In addition, when the hot air is blown out, it can also blow away the dust from the dust collection screen and the surface of the LED bulb, playing a certain role in dust removal.

[0014] 2. This utility model, through the arrangement of a dust removal mechanism, a movable cylinder, a brush, a crossbeam, and a turbine fan, allows the silent fan to work. When the fresh air blows downwards, it causes the turbine fan to rotate, which in turn drives the entire movable cylinder to rotate through the crossbeam. At this time, the brush will brush against the surface of the dust collection net, thereby wiping away a large amount of attached dust, which is then blown off with the exhaust air, thus achieving an effective dust removal effect and thoroughly removing dust.

[0019] 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.

[0020] like Figures 1-3As shown, a heat-dissipating and dust-removing LED downlight includes a housing 1, a cavity 2 is formed in the inner wall of the housing 1, a silent fan 3 is fixedly installed on the upper end of the inner surface of the cavity 2, a dust collection net 4 is fixedly installed on the inner surface of the housing 1, and the same dust removal mechanism 5 is provided in the cavity 2 and the inner wall of the inner circular surface of the housing 1.

[0021] By adopting the above technical solution, the silent fan 3 will draw in fresh air from the outside and blow it onto the circuit board 7 to cool down the circuit board 7;

[0022] The surface of the dust collection mesh 4 absorbs a small amount of weak current during the operation of the downlight, generating static electricity on the surface, which in turn attracts dust from inside the downlight and reduces the amount of dust adhering to the light-emitting components of the downlight.

[0023] Furthermore, the dust removal mechanism 5 includes a movable cylinder 501 rotatably mounted on the inner wall of the inner circular surface of the housing 1, with the outer circular surface of the movable cylinder 501 protruding from the interior of the cavity 2; the dust removal mechanism 5 also includes a brush 502 fixedly disposed on the inner surface of the movable cylinder 501, with the brush 502 attached to the surface of the dust collection screen 4; the dust removal mechanism 5 also includes a crossbeam 503 fixedly mounted on the upper end of one side of the movable cylinder 501 inside the cavity 2, with a turbo fan 504 fixedly mounted on the upper surface of the crossbeam 503, and the turbo fan 504 being vertically opposite to the silent fan 3.

[0024] By adopting the above technical solution, when the silent fan 3 is working, the fresh air will blow downwards to make the turbofan 504 rotate, which in turn drives the entire movable cylinder 501 to rotate through the cross frame 503. At this time, the brush 502 will brush against the surface of the dust collection net 4 to remove a large amount of dust.

[0025] Furthermore, a ventilation opening 6 is provided through the surface of the movable cylinder 501, which connects the cavity 2 with the interior of the shell 1.

[0026] By adopting the above technical solution, the hot air generated inside the entire device is carried by the fresh air flow and blown out to the outside through the vent 6 from the cavity 2. This can effectively cool down the entire downlight. In addition, when the hot air is blown out, it can also scrape off the loose dust from the dust collection screen 4 and blow off the small amount of dust adhering to the surface of the LED bulb 8.

[0027] Furthermore, a circuit board 7 is fixedly installed on the top of the inner surface of the housing 1, and an LED bulb 8 is installed on the lower surface of the circuit board 7 by means of a threaded connection; the circuit board 7 is located inside the dust collection screen 4.

[0028] By adopting the above technical solution, the circuit board 7 provides light-emitting energy for the LED bulb 8, and at the same time, a small amount of the current generated will be absorbed by the dust collection net 4, causing the dust collection net 4 to generate static electricity and fully adsorb dust.

[0029] Working Principle: When using this heat-dissipating and dust-removing LED downlight, firstly, the circuit board 7 provides power to the LED bulb 8, and a small amount of the generated power is absorbed by the dust collection net 4, causing the dust collection net 4 to generate static electricity, which fully adsorbs dust, reducing the amount of dust adhering to the LED bulb 8 and ensuring that the LED bulb 8 lights up normally. At this time, the silent fan 3 draws in fresh air from the outside and blows it onto the circuit board 7 to cool the circuit board 7. The fresh air flow carries away the heat generated inside the entire device and blows it out to the outside through the vent 6 from the cavity 2, effectively cooling the entire downlight. When the silent fan 3 is working, the fresh air blows downward, causing the turbine fan 504 to rotate, which in turn drives the entire movable cylinder 501 to rotate through the cross frame 503. At this time, the brush 502 brushes against the surface of the dust collection net 4, thereby wiping away a large amount of dust, which is then blown off with the exhaust air, thus achieving an effective dust removal effect. This is the working principle of this heat-dissipating and dust-removing LED downlight.
