A lighting fixture with good heat dissipation effect

Abstract

The present invention relates to the technical field of heat dissipation of lighting fixtures, and particularly relates to a lighting fixture with good heat dissipation effect. In order to solve the problem that impurities or dust block the heat dissipation ports due to the inability to clean for a long time, resulting in a reduction in the heat dissipation efficiency of the lighting fixture, the present invention transmits the thermal resistance to the signal conversion module through the thermistor plate, and then the signal conversion module converts it into voltage to the electric telescopic rod, so that the electric telescopic rod drives the filter component and the cleaning component to move together. Due to the repulsion between magnet A and magnet B, and the movement of magnet A, the movable plate will reciprocate up and down to scrape off the impurities on the surface of the heat dissipation net. On the one hand, the reciprocating movement of the heat dissipation net can shake off the impurities, and on the other hand, it drives the short plate to reciprocate as well, so that the reciprocating short plate can uniformly discharge the scraped impurities into the collection box, thus improving the heat dissipation effect of the lighting fixture.

Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of lighting fixtures, and particularly relates to a lighting fixture with good heat dissipation effect. Background Art

[0002] Heat dissipation of lighting fixtures is a key link to ensure their stable operation and extend their service life. Since part of the electrical energy is converted into heat energy when the lamps are working, if the heat accumulates, it will affect the luminous efficiency, shorten the service life of the light source and even cause potential safety hazards. Therefore, various heat dissipation methods are often used to solve this problem. For example, metal heat sinks are used to increase the heat dissipation area, and natural convection is relied on to dissipate the heat into the surrounding air; or active heat dissipation devices such as fans are used to force the air flow to accelerate heat dissipation; some high-end lamps also use high-efficiency heat dissipation technologies such as heat pipes to quickly and efficiently transfer the heat, ensuring that the lighting fixtures are always at an appropriate working temperature.

[0003] In the Chinese patent with the application number CN201510318906.2, a household lighting fixture is disclosed. By arranging a heat dissipation component and a heat dissipation piece that are mutually abutted, and installing the LED lamp on the heat dissipation component, the heat dissipation component and the heat dissipation piece cooperate to dissipate heat, which can greatly improve the heat dissipation performance of the household lighting fixture. In addition, the above-mentioned household lighting fixture also has the advantage of relatively high safety performance.

[0004] In the above patent during operation, the lighting fixture usually dissipates heat through its own heat dissipation ports when dissipating heat. However, since lighting fixtures are usually hung high and no one often cleans the lighting fixtures, over time, impurities or dust will block the heat dissipation ports. Once the heat dissipation ports are blocked, the heat dissipation effect of the lighting fixture will decline, resulting in the problem of reducing the heat dissipation efficiency of the lighting fixture.

[0005] Therefore, we propose a lighting fixture with good heat dissipation effect. Summary of the Invention

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1. To solve the technical problem of how to improve the heat dissipation of lighting fixtures, as Figures 1 - 6 shown, the following preferred technical solutions are provided:

[0036] A lighting fixture with good heat dissipation effect, comprising a mounting plate (1). A dust-proof component (2) for blocking dust is fixedly installed on the lower surface of the mounting plate (1). A base (3) is fixedly installed on the lower surface of the dust-proof component (2). A lamp bead board (4) is arranged inside the base (3). A driving power source (41) is fixedly installed on the surface of the lamp bead board (4). A partition groove (11) is formed in the inner wall of the mounting plate (1);

[0037] The dust-proof component (2) includes a dust-proof shell (21) fixedly installed on the lower surface of the mounting plate (1), empty slots (22) opened on both sides of the inner wall of the dust-proof shell (21), and racks (23) fixedly installed on the inner walls of the empty slots (22). A filter component (25) for filtering dust and dissipating heat is movably installed on the inner wall of the empty slot (22). A cleaning component (26) for removing dust on the surface of the filter component (25) is movably arranged on the outer surface of the dust-proof shell (21). A linkage component (24) for driving the filter component (25) and the cleaning component (26) to operate is fixedly installed on the other side of the inner wall of the dust-proof shell (21). An electric telescopic rod (241) is fixedly installed on the inner wall of the dust-proof shell (21). One end of the electric telescopic rod (241) is fixedly installed with a Z-shaped plate (242). A long rod (244) is rotatably arranged on the lower surface of the Z-shaped plate (242). Teeth (245) and rollers (246) are fixedly installed on the outer surface of the long rod (244). The roller (246) is located on one side of the filter component (25). One end of the Z-shaped plate (242) and the magnet A (243) are located inside the partition slot (11). The teeth (245) are located on one side of the rack (23). The rack (23) is meshed with the teeth (245). The temperature generated by the drive power supply 41 can be detected by the thermistor plate 42. Subsequently, the thermistor plate 42 will convert the rising temperature into a resistance value. Then, the resistance value will be electrically transmitted to the signal conversion module 46. The signal conversion module 46 will convert the resistance value into a voltage signal and transmit it to the electric telescopic rod 241 through a wire. Subsequently, the electric telescopic rod 241 will move according to the level of temperature change. The moving linkage component 24 drives the filter component 25 and the cleaning component 26 to move together. At this time, the lighting fixture can not only dissipate heat for itself through the filter component 25 but also isolate a large amount of dust and impurities on the outer surface of the dust-proof shell 21. Finally, through the operation of the filter component 25 itself and the operation of the cleaning component 26, the blocked impurities and dust on the surface of the filter component 25 can be uniformly removed, further improving the heat dissipation effect of the filter component 25. When the electric telescopic rod 241 moves, at this time, the long rod 244 on the lower surface of one end of the moving electric telescopic rod 241 will start to rotate because the teeth 245 are meshed with the rack 23, so that the roller 246 rotates. Since the long rod 244 is not at the central position of the roller 246, when the long rod 244 drives the roller 246 to rotate half a circle, the roller 246 will contact the filter component 25, thereby driving the filter component 25 to move. When the roller 246 rotates half a circle again, the roller 246 will move away from the filter component 25, so that the filter component 25 itself can be reset. The reciprocating moving filter component 25 can remove the impurities and dust on the surface.

[0038] A lamp shade (5) is arranged on the lower surface of the base (3). A thermistor plate (42) is fixedly installed on the surface of the drive power supply (41). A signal conversion module (46) is fixedly installed on the surface of the base (3);

[0039] The electric telescopic rod (241) is linearly connected to the thermistor plate (42), the thermistor plate (42) is signal-connected to the signal conversion module (46), the signal conversion module (46) is electrically connected to the electric telescopic rod (241), a magnet A (243) is fixedly mounted on the lower surface of the Z plate (242), and the resistance value of the temperature of the lamp bead plate (4) itself can be monitored in real time through the thermistor plate 42, and then the thermistor plate 42 and the signal conversion module 46 convert the resistance value into a voltage, which is then transmitted to the electric telescopic rod 241 through the wire, thereby starting the electric telescopic rod 241 and allowing the electric telescopic rod 241 to complete the subsequent dust cleaning work.

[0040] The filter assembly 25 includes a heat dissipation net 251 movably arranged on the inner wall of the hollow groove 22, a roller 246 located at one side of the heat dissipation net 251, a sleeve 252 fixedly installed on the lower surface of the heat dissipation net 251, and a spring A254 fixedly installed on one side of the sleeve 252, baffles 253 are fixedly installed on both sides of the sleeve 252, and the baffles 253 are located above the spring A254. The scraped impurities can be isolated on the surface of the base 3 through the baffles 253, and then the heat dissipation net 251 that is squeezed and moved can be reset through the spring A254, waiting for the next squeezing of the roller 246, so that the heat dissipation net 251 can produce a reciprocating movement effect, thereby shaking off the impurities and dust on the surface of the heat dissipation net 251, ensuring the patency of the heat dissipation port.

[0041] The cleaning assembly 26 includes a movable plate 261 disposed on one side of the filter assembly 25, a rod hole 262 provided on the surface of the movable plate 261, and a magnet B263 embedded on the surface of the movable plate 261, the magnet B263 and the magnet A243 magnetically repel each other, an inner groove 264 is provided inside the movable plate 261, a spring rod A266 is fixedly installed on the inner wall of the inner groove 264, a scraper 265 is fixedly installed on one end of the spring rod A266, and one end of the scraper 265 is in contact with one side of the heat dissipation net 251;

[0042] A vertical rod 31 is fixedly installed on the surface of the base 3. A spring B311 is arranged on the outer surface of the vertical rod 31. One end of the spring B311 is fixedly connected to the lower surface of the movable plate 261, and the other end of the spring B311 is fixedly connected to the upper surface of the base 3. The rod hole 262 is adapted to the vertical rod 31. The movable plate 261 can be lowered by the magnet B263 and the magnet A243, and then the movable plate 261 can be raised by the spring B311. When the magnet A243 gradually approaches the magnet B263, the movable plate 261 will descend due to the repulsive force between the magnet B263 and the magnet A243. When the magnet A243 moves between the two groups of magnets B263, the repulsive force between the magnet B263 and the magnet A243 will disappear. At this time, the spring B311 will drive the movable plate 261 to rise and reset. At this time, the reciprocatingly lifting movable plate 261 will further scrape the impurities on the surface of the heat dissipation net 251 through the scraper 265, thereby further improving the cleaning effect.

[0043] A cross rod 271 is movably arranged inside the short board 27. One end of the cross rod 271 is fixedly installed with a turning plate 272, and the other end of the cross rod 271 is fixedly installed with a dial plate 273. The dial plate 273 is attached to the upper surface of the base 3. The short board 27 can drive the dial plate 273 to reciprocate together with the heat dissipation net 251, so as to remove the swept impurities together. When the short board 27 reciprocates, the turning plate 272 can also cooperate with the rectangular block 28 to make the dial plate 273 perform a reciprocating turning motion, preventing the dial plate 273 from driving the dust to move reciprocally.

[0044] A chute 281 is opened on one side of the rectangular block 28, and a long groove 282 is opened inside the rectangular block 28. The chute 281 is communicated with the long groove 282. The chute 281 is slidably connected to the cross rod 271, and the long groove 282 is slidably connected to the turning plate 272. A storage groove 283 is opened on the inner wall of the long groove 282. A spring rod B284 is fixedly installed inside the storage groove 283. One end of the spring rod B284 is fixedly installed with a limit block 285. One end of the limit block 285 is provided with a slope A286. The upper surface of the turning plate 272 is on the same horizontal line as the upper surface of the limit block 285. Through the limit block 285 and the slope A286, when the turning plate 272 moves towards one end, the turning plate 272 can squeeze the slope A286 to make the slope A286 enter the storage groove 283. When the turning plate 272 returns, the upper half of the turning plate 272 will contact one side of the limit block 285, so that the turning plate 272 is inclined. At this time, the dial plate 273 will follow the turning plate 272 to turn together, so that the lower surface of the dial plate 273 is far away from the upper surface of the base 3, so that the dial plate 273 can be separated from the dust.

[0045] Specifically, after the lighting fixture has been used for a long time, the thermistor plate 42 will detect the temperature value of the rising temperature of the drive power supply 41 and convert it into the resistance value of the thermal resistance, and transmit it to the signal conversion module 46 through the wire. At this time, the signal conversion module 46 will convert the resistance value into voltage and then transmit it to the electric telescopic rod 241 through the wire, so that the electric telescopic rod 241 starts and drives the Z plate 242 to move. As the Z plate 242 moves, the magnet A 243 on the lower surface of one end of the Z plate 242 will gradually approach the magnet B 263 on the surface of the movable plate 261. Due to the magnetic repulsion between the magnet A 243 and the magnet B 263, the movable plate 261 will descend, driving the scraper 265 to scrape on the surface of the heat dissipation net 251, scraping the impurities to the surface of the base 3. As the Z plate 242 moves, the magnet A 243 will be misaligned with the magnet B 263. At this time, the spring B 311 will drive the movable plate 261 to reset, thus driving the movable plate 261 to rise and wait for the next descent. Just as the Z plate 242 moves to drive the movable plate 261 to descend, the long rod 244 on the lower surface of one end of the Z plate 242 will rotate because the tooth 245 meshes with the rack 23, driving the long rod 244 to rotate. Since the roller 246 and the center of the long rod 244 are not on the same vertical line, when the long rod 244 drives the roller 246 to rotate, half of the roller 246 will squeeze the heat dissipation net 251, causing the heat dissipation net 251 to move, while the other half of the roller 246 does not contact the heat dissipation net 251. At this time, the heat dissipation net 251 will be reset by the spring A 254 until the roller 246 contacts the heat dissipation net 251 again. At this time, the reciprocating heat dissipation net 251 can shake off the impurities on the surface. Since the scraper 265 is movably arranged inside the inner groove 264 through the spring rod A 266, when the heat dissipation net 251 moves forward, the scraper 265 will be pressed back into the inner groove 264. Since one end of the scraper 265 is always in close contact with one side of the heat dissipation net 251, when the heat dissipation net 251 moves, the scraper 265 can still scrape off the impurities attached to the surface of the heat dissipation net 251. Just as the heat dissipation net 251 reciprocates, the short board 27 on one side of the heat dissipation net 251 will drive the dial 273 to reciprocate as well. At this time, when the turning plate 272 fixedly installed on one side of the cross bar 271 moves forward, one side of the turning plate 272 will contact the slope A 286 at one end of the limit block 285, and the limit block 285 will be squeezed into the storage groove 283. At this time, the dial 273 moves vertically forward, moving the impurities forward. When the dial 273 reaches the top, the limit block 285 will pop out again. At this time, the returning side of the turning plate 272 will contact the flat surface at the other end of the limit block 285, thus driving the dial 273 to tilt and return obliquely. The reciprocating dial 273 will sweep the impurities into the collection box 39 uniformly. Thus, when the temperature of the drive power supply 41 rises, the linkage assembly 24, the filtering assembly 25, and the cleaning assembly 26 can clean the impurities on the surface of the heat dissipation net 251.Thereby improving the heat dissipation effect of the lighting fixture.

[0046] Embodiment 2 is to solve the technical problem of how to improve the installation efficiency of the lighting fixture. As Figures 6 - 9 shown, the following preferred technical solutions are provided:

[0047] On the upper surface of the base 3, there are a hole groove 32 and a short groove 33. The hole groove 32 is adapted to the driving power supply 41, and the short groove 33 is adapted to the sleeve plate 252. A guide rod is fixedly installed on the inner wall of the short groove 33, and the guide rod is adapted to the holes provided on the surface of the sleeve plate 252. The spring A 254 is located on the outer surface of the guide rod. On both sides of the inner wall of the short groove 33, there are storage grooves 331, and the storage grooves 331 are adapted to the baffle plate 253. On both sides of the base 3, there are narrow grooves 36. At the bottom of the base 3, there is a rectangular groove 363, and the rectangular groove 363 is connected to the narrow groove 36. A sliding plate 361 is movably arranged on the inner wall of the rectangular groove 363.
