Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation of lighting fixtures, and in particular 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 electrical energy will be partially converted into heat energy when the lamp is working, if heat accumulates, it will affect the luminous efficiency, shorten the life of the light source, and even cause safety hazards. Therefore, it is often solved through a variety of heat dissipation methods, such as using metal heat sinks to increase the heat dissipation area and rely on natural convection to dissipate heat to the surrounding air; or using active heat dissipation devices such as fans to force air flow to accelerate heat dissipation; some high-end lamps also use efficient heat dissipation technologies such as heat pipes to quickly and efficiently transfer heat to ensure that the lighting fixture is always at a suitable working temperature.

[0003] In the Chinese patent application number CN201510318906.2, a household lighting fixture is disclosed. By providing a heat dissipation assembly and a heat dissipation member that abut against each other, and installing an LED lamp on the heat dissipation assembly, the heat dissipation assembly and the heat dissipation member 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 high safety performance.

[0004] In the operation of the above-mentioned patent, the lighting fixture usually dissipates heat through its own heat dissipation vents. However, since the lighting fixtures are hung high up and no one cleans the lighting fixtures regularly, the heat dissipation vents may be blocked by impurities or dust over a long period of time. Once the heat dissipation vents are blocked, the heat dissipation effect of the lighting fixture will decrease, resulting in a problem of reduced heat dissipation efficiency of the lighting fixture.

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

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1, in order to solve the problem of how to improve the heat dissipation technology of lighting fixtures, such as Figure 1-Figure 6 As shown, the following preferred technical solutions are provided: A lighting fixture with good heat dissipation effect, comprising a mounting plate (1), a dustproof component (2) for blocking dust being fixedly mounted on the lower surface of the mounting plate (1), a base (3) being fixedly mounted on the lower surface of the dustproof component (2), a lamp bead plate (4) being arranged inside the base (3), a driving power source (41) being fixedly mounted on the surface of the lamp bead plate (4), and a partition groove (11) being provided on the inner wall of the mounting plate (1); The dustproof component (2) comprises a dustproof shell (21) fixedly mounted on the lower surface of the mounting plate (1), hollow grooves (22) provided on both sides of the inner wall of the dustproof shell (21), and racks (23) fixedly mounted on the inner wall of the hollow groove (22); a filter assembly (25) for filtering dust and dissipating heat is movably mounted on the inner wall of the hollow groove (22); a cleaning assembly (26) for removing dust from the surface of the filter assembly (25) is movably arranged on the outer surface of the dustproof shell (21); a linkage assembly (24) for driving the filter assembly (25) and the cleaning assembly (26) to operate is fixedly mounted on the other side of the inner wall of the dustproof shell (21); and an electric telescopic rod (24) is fixedly mounted on the inner wall of the dustproof shell (21). 1), a Z plate (242) is fixedly mounted on one end of the electric telescopic rod (241), a long rod (244) is rotatably mounted on the lower surface of the Z plate (242), teeth (245) and a roller (246) are fixedly mounted on the outer surface of the long rod (244), the roller (246) is located on one side of the filter assembly (25), one end of the Z plate (242) and the magnet A (243) are located inside the partition (11), the teeth (245) are located on one side of the rack (23), the rack (23) and the teeth (245) are meshed, the temperature generated by the driving power supply 41 can be detected through the thermistor plate 42, and then the thermistor plate 42 will convert the increased temperature into a resistance value, and then the resistance value will be passed The over-electricity is transmitted to the signal conversion module 46, and the signal conversion module 46 will convert the resistance into a voltage signal and transmit it to the electric telescopic rod 241 through the wire. Then the electric telescopic rod 241 will move according to the temperature change, and the moving linkage component 24 will move with the filter component 25 and the cleaning component 26. 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 dustproof shell 21. Finally, through the operation of the filter component 25 itself and the operation of the cleaning component 26, the impurities and dust blocked on the surface of the filter component 25 can be uniformly removed, thereby further improving the heat dissipation effect of the filter component 25. 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, thereby causing the long rod 244 to rotate, thereby causing the roller 246 to rotate. Since the long rod 244 is not at the center of the roller 246, when the long rod 244 rotates half a circle with the roller 246, the roller 246 will contact the filter assembly 25, thereby moving the filter assembly 25. When the roller 246 rotates half a circle again, the roller 246 will move away from the filter assembly 25, thereby allowing the filter assembly 25 to reset itself. The reciprocating filter assembly 25 can remove impurities and dust on the surface.

[0022] A lampshade (5) is provided on the lower surface of the base (3), a thermistor plate (42) is fixedly mounted on the surface of the driving power source (41), and a signal conversion module (46) is fixedly mounted on the surface of the base (3); 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.

[0023] 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.

[0024] 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; A vertical rod 31 is fixedly installed on the surface of the base 3, and a spring B311 is provided 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 and the magnet B263 gradually approach each other, the movable plate 261 will drop 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 bring the movable plate 261 up and reset. At this time, the reciprocating movable plate 261 will further scrape off the impurities on the surface of the heat dissipation net 251 through the scraper 265, thereby further improving the cleaning effect.

[0025] A cross bar 271 is movably provided inside the short plate 27, a flip plate 272 is fixedly installed at one end of the cross bar 271, and a paddle plate 273 is fixedly installed at the other end of the cross bar 271. The paddle plate 273 is in contact with the upper surface of the base 3. The short plate 27 can drive the paddle plate 273 to move back and forth along with the heat dissipation net 251, so as to remove the cleaned impurities together. The flip plate 272 can also cooperate with the rectangular block 28 to make the paddle plate 273 perform reciprocating flipping motion when the short plate 27 moves back and forth, so as to prevent the paddle plate 273 from reciprocating with dust.

[0026] A slide groove 281 is provided on one side of the rectangular block 28, a long groove 282 is provided inside the rectangular block 28, the slide groove 281 is connected with the long groove 282, the slide groove 281 is slidably connected with the cross bar 271, the long groove 282 is slidably connected with the flip plate 272, a storage groove 283 is provided on the inner wall of the long groove 282, a spring rod B284 is fixedly installed inside the storage groove 283, a limit block 285 is fixedly installed at one end of the spring rod B284, a slope A286 is provided at one end of the limit block 285, and the upper surface of the flip plate 272 and the upper surface of the limit block 285 are at the same level. On the horizontal line, through the limit block 285 and the slope A286, when the flip plate 272 moves to one end, the flip plate 272 can squeeze the slope A286 to allow the slope A286 to enter the storage slot 283. When the flip plate 272 returns, the upper part of the flip plate 272 will contact one side of the limit block 285, thereby causing the flip plate 272 to tilt. At this time, the dial plate 273 will flip along with the flip plate 272, so that the lower surface of the dial plate 273 is away from the upper surface of the base 3, thereby allowing the dial plate 273 to be separated from dust.

[0027] Specifically, after the lighting fixture has been used for a long time, the thermistor plate 42 will detect the temperature value of the driving power supply 41 and convert the temperature value into the resistance value of the thermal resistor, which will be transmitted to the signal conversion module 46 through the wire. At this time, the signal conversion module 46 will convert the resistance value into a voltage, and then transmit it to the electric telescopic rod 241 through the wire, so that the electric telescopic rod 241 is started and moves with the Z plate 242. As the Z plate 242 moves, the magnet A243 located on the lower surface of one end of the Z plate 242 will gradually approach the magnet B263 on the surface of the movable plate 261. Due to the magnetic repulsion between the magnet A243 and the magnet B263, the movable plate 261 will descend, and the scraper 265 will scrape the surface of the heat dissipation net 251 to scrape the impurities to the surface of the base 3. As the Z plate 242 moves, the magnet A243 will be misaligned with the magnet B263. At this time, the spring B311 will reset the movable plate 261, thereby raising the movable plate 261 and waiting for the next descent. When the Z plate 242 moves and drives the movable plate 261 to descend, the long rod 244 located on the lower surface of one end of the Z plate 242 will be meshed with the rack 23 due to the teeth 245, thereby driving the long rod 244 to rotate. Since the centers of the roller 246 and the long rod 244 are not on the same vertical line, when the long rod 244 rotates with the roller 246, half of the roller 246 will squeeze the heat sink 251 to move the heat sink 251, while the other half of the roller 246 is not in contact with the heat sink 251. At this time, the heat sink 251 will The spring A254 is used to reset 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 A266, 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 tightly fitted 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. When the heat dissipation net 251 moves back and forth, the short plate 27 located on one side of the heat dissipation net 251 will also move back and forth with the paddle 273. At this time, one side of the cross bar 271 is fixedly installed When the installed flip plate 272 moves forward, one side of the flip plate 272 will contact the slope A286 at one end of the limit block 285, and the limit block 285 will be squeezed into the storage slot 283. At this time, the dial plate 273 moves vertically to move the impurities forward. When the dial plate 273 reaches the top, the limit block 285 will pop up again. At this time, the returning side of the flip plate 272 will contact the plane at the other end of the limit block 285, thereby tilting the dial plate 273, allowing the dial plate 273 to return tilted, and the reciprocating dial plate 273 will uniformly sweep the impurities into the collection box 39. At this point, when the temperature of the driving power supply 41 rises, the linkage component 24, the filter component 25, and the cleaning component 26 can clean the impurities on the surface of the heat dissipation network 251.Thereby improving the heat dissipation effect of lighting fixtures.
