Description
Technical Field
[0001] This utility model relates to the technical field of lighting fixtures, specifically to a heat dissipation ceiling light. Background Technology
[0002] Ceiling lights are a type of lighting fixture. They are relatively flat on top and are installed with the bottom completely flush with the ceiling, hence the name ceiling lights. They are mainly used in various places such as homes, offices, and entertainment venues, and are very versatile. Commonly used ceiling lights include: square ceiling lights, round ceiling lights, pointed flat round ceiling lights, and hemispherical ceiling lights.
[0003] Existing square ceiling lights are rectangular in shape and are mainly installed in hallways and bathrooms. When in use, the reflected light from the internal LED beads generates heat. As the lighting time increases, this heat accumulates and affects the normal operation of the square ceiling light. To ensure long-term operation, ventilation holes are usually made on the inner wall of the square ceiling light for heat dissipation. However, when using ventilation holes for heat dissipation, dust from the installation environment can easily enter the interior of the square ceiling light with the airflow, which can affect the lighting effect and lifespan of the square ceiling light.
[0004] In view of this, we propose a heat-dissipating ceiling light. Utility Model Content
[0005] The purpose of this invention is to provide a heat-dissipating ceiling light to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides a heat dissipation ceiling light, including a square ceiling light and a heat dissipation structure disposed inside the square ceiling light. A conductive support is installed on the top of the square ceiling light, and a conductive cable extending to the outside is disposed through the interior of the conductive support. The conductive cable is connected to a lighting system installed inside the square ceiling light.
[0007] The heat dissipation structure includes dust-collecting fins, which are installed on the side of the connecting part. The connecting part is installed on the inside of the heat dissipation outer frame, which is located inside the heat dissipation cavity. The heat dissipation cavity is opened on the left and right sides of the square ceiling light. An internal frame is installed on the inside of the heat dissipation outer frame and is installed inside the square ceiling light. Dust-proof nets are detachably installed on the front and rear sides inside the internal frame, and a lighting system is provided on the inside of the internal frame.
[0008] As a further improvement to this technical solution, the square ceiling light consists of a top lampshade, a bottom lampshade, and a protective cover. A conductive support is installed at the top center of the top lampshade, and the bottom lampshade is installed at the bottom of the top lampshade by bolts. The protective cover is snapped into the inner bottom of the bottom lampshade. A lighting system is provided in the central part inside the top lampshade and the bottom lampshade.
[0009] As a further improvement to this technical solution, heat dissipation cavities are provided in the center of the left and right sides of the top lampshade and the bottom lampshade, and the interior of the heat dissipation cavity protrudes inward to form a protrusion, and the protrusion is slidably connected to the recessed groove opened inside the heat dissipation outer frame.
[0010] The upper and lower sides of the heat dissipation outer frame are also equipped with airbags located on the inner wall of the heat dissipation cavity.
[0011] As a further improvement to this technical solution, the several fin components inside the dust collection fins are all arranged obliquely, and two sets of fin components that are close to each other form a "V" shape.
[0012] In this configuration, the roots of two adjacent sets of fin components are provided with openings.
[0013] As a further improvement to this technical solution, the internal frame is respectively installed on the inner side of the top lampshade and the bottom lampshade, and the two sets of internal frames located on the inner side of the top lampshade and the bottom lampshade abut and fit together.
[0014] The dust-proof mesh is arranged perpendicularly to the dust-collecting fins.
[0015] As a further improvement to this technical solution, the lighting system includes at least a power module, which is installed at the bottom of the top lampshade and connected to a conductive cable. A lamp head module is linearly connected to the bottom of the power module and is installed at the inner bottom of the bottom lampshade. Both the power module and the lamp head module are located inside the internal frame, and the lamp head module is installed above the protective cover.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This heat-dissipating ceiling light generates and accumulates a significant amount of heat during prolonged operation of the lamp head module. Through the bent internal frame's external space, dust filter, and angled dust-collecting fins, it effectively traps dust from the outside air during heat dissipation and interaction with external gases. This is achieved through the adhesion of dust within the dust-collecting fins (via the internal fin components), the angled cut-in (via the bent space outside the internal frame), and the sieving and isolation (via the angled cut-in gas and dust filter). This reduces the probability of dust from the external environment entering and accumulating inside the ceiling light, thus improving its lighting effect and lifespan. Attached Figure Description

[0025] To enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.
[0026] Please see Figure 1As shown in Figure 5, this embodiment provides a heat-dissipating ceiling light, including a square ceiling light 10 and a heat dissipation structure 20 disposed inside the square ceiling light 10. A conductive support 30 is installed on the top of the square ceiling light 10, and a conductive cable 30i extending to the outside is disposed through the interior of the conductive support 30. The conductive cable 30i is connected to a lighting system 40 installed inside the square ceiling light 10. The heat dissipation structure 20 includes dust-collecting fins 201, which are installed on the connecting... On the side of the connecting part 202, the connecting part 202 is installed on the inner side of the heat dissipation outer frame 203. The heat dissipation outer frame 203 is located inside the heat dissipation cavity 204. The heat dissipation cavity 204 is opened on the left and right sides of the square ceiling light 10. An inner frame 205 is installed on the inner side of the heat dissipation outer frame 203. The inner frame 205 is installed inside the square ceiling light 10. Dust screens 206 are detachably installed on the front and rear sides inside the inner frame 205. A lighting system 40 is provided on the inner side of the inner frame 205.
[0027] The working principle described above is as follows: When the square ceiling light 10 is used, as the lighting system 40 operates for a long time, the internal lighting beads will generate heat due to their light emission. At this time, the space between the internal frame 205 and the lighting system 40, and between the internal frame 205 and the heat dissipation cavity 204, facilitates the transfer of heat to the external environment through the heat dissipation cavity 204, achieving automatic heat dissipation. Furthermore, during automatic heat dissipation, air and dust from the external environment are transferred to the heat dissipation cavity 204 through the dust suction fins 201. 04. The air will first come into contact with the dust-collecting fins 201 on the outside of the internal frame 205. The dust-collecting fins 201 will then perform the initial adsorption of the circulating gas. The gas entering the outside of the internal frame 205 will be transported through a bend and cut obliquely into the dust filter 206. At this time, the dust filter 206 is designed to further screen and isolate the dust inside the circulating gas, minimizing the probability of external dust entering the lighting system 40 during heat dissipation and affecting the light cover strength and lifespan.
[0028] For details, please refer to the following: Figure 1 , Figure 3 and Figure 4 The square ceiling light 10 consists of a top lampshade 101, a bottom lampshade 102, and a protective cover 103. A conductive support 30 is installed at the top center of the top lampshade 101. The bottom lampshade 102 is installed at the bottom of the top lampshade 101 by bolts. The protective cover 103 is snapped into the inner bottom of the bottom lampshade 102.
[0029] In this embodiment, a lighting system 40 is provided in the central part inside the top lampshade 101 and the bottom lampshade 102. The lighting system 40 can be assembled and supported by the design of the top lampshade 101 and the bottom lampshade 102.
[0030] For details, please refer to the following: Figure 1 , Figure 4 and Figure 5 In addition, in this embodiment, heat dissipation cavities 204 are provided in the center of the left and right sides of the top lampshade 101 and the bottom lampshade 102, and the interior of the heat dissipation cavity 204 protrudes inward to form a protrusion 204a. The protrusion 204a and the recessed groove 204b opened in the heat dissipation outer frame 203 are slidably connected. Through the design of the protrusion 204a and the recessed groove 204b, when the ceiling light 10 is actually assembled, the two sets of heat dissipation outer frames 203 and their internal dust suction fins 201 and connecting parts 202 can be installed into the interior of the heat dissipation cavity 204 respectively.
[0031] In conjunction with this, airbags 203i are installed on the upper and lower sides of the heat dissipation outer frame 203, located on the inner wall of the heat dissipation cavity 204. The airbags 203i can be restored by the elasticity of the air to achieve a tight fit and contact between the two sets of heat dissipation outer frames 203.
[0032] For details, please refer to the following: Figure 5 Furthermore, in this embodiment, the plurality of fin components 201a disposed inside the dust suction fin 201 are all obliquely arranged, and two sets of fin components 201a that are close to each other form a "V" shape. By the oblique arrangement of the fin components 201a, when the outside gas enters the top lampshade 101 and the bottom lampshade 102 through the dust suction fin 201, the contact surface with the incoming gas can be expanded (by oblique cutting), thereby increasing the area of the dust suction fin 201 for adsorbing dust.
[0033] In conjunction with this, the roots of the two adjacent sets of fin components 201a are set with openings to ensure the space for normal gas (external environment and internal hot air) transmission.
[0034] In the actual heat dissipation process of the heat-dissipating ceiling light of this application, the heat generated by the operation of the internal lighting system 40 can be transferred to the external environment through the dust filter 206, the channel between the top lampshade 101 and the bottom lampshade 102 and the internal frame 205 support, and the heat dissipation cavity 204, respectively, thus completing the heat dissipation. The external gas that is transferred for heat dissipation can enter the interior of the lighting system 40 through the fin component 201a inside the dust suction fin 201, the bent transmission path (the channel between the top lampshade 101 and the bottom lampshade 102 and the internal frame 205 support), and the dust filter 206. In the entire heat exchange process, the probability of dust entering the interior of the lighting system 40 is effectively reduced.
[0035] For details, please refer to the following: Figure 4 The internal frame 205 is installed on the inner side of the top lampshade 101 and the bottom lampshade 102 respectively, and the two sets of internal frames 205 located on the inner side of the top lampshade 101 and the bottom lampshade 102 abut and fit together.
[0036] In this embodiment, the dust filter 206 and the dust suction fins 201 are arranged perpendicularly to each other. By setting the positions of the dust filter 206 and the dust suction fins 201, the gas entering the top lampshade 101 and the bottom lampshade 102 will first be transmitted through the bent channel, ensuring that the transmitted gas can cut into the dust filter 206 at an angle, thereby improving the effect of the dust filter 206 in screening dust in the gas.
[0037] For details, please refer to the following: Figure 1 and Figure 4 The lighting system 40 includes at least a power module 401, which is installed at the bottom of the top lampshade 101. The power module 401 is connected to a conductive cable 30i. A lamp head module 402 is linearly connected to the bottom of the power module 401 and is installed at the inner bottom of the bottom lampshade 102.
[0038] In this embodiment, both the power module 401 and the lamp head module 402 are located inside the internal frame 205. The lamp head module 402 is installed above the protective cover 103. The internal frame 205 can be used to install, position, and protect the power module 401 and the lamp head module 402.
[0039] The heat-dissipating ceiling light of this application includes a power supply module 401 that includes at least a driver power supply (constant current power supply) and a transformer (to ensure that the current can complete the illumination of the lamp head module 402); the lamp head module 402 includes at least LED lighting beads (light emission) and an LED chip circuit board (for mounting LED lighting beads).
