Description

Technical Field

[0001] This invention belongs to the field of circuit board technology, and specifically relates to an LED lamp circuit board. Background Technology

[0002] Circuit boards are the support for electronic components and the provider of electrical connections for them. An LED light is an electroluminescent semiconductor chip that is cured onto a support with silver or white glue. Then, silver or gold wires are used to connect the chip and the circuit board, and the surrounding area is sealed with epoxy resin. Because high-power LEDs generate a lot of heat, most aluminum substrates are used in the production of LED lighting fixtures.

[0003] In existing LED light circuit boards with good heat dissipation performance, heat is dissipated by blowing air out of the built-in fan or by adding heat sinks to the circuit board. However, the structure is complex and the operating temperature of LED lights can reach 65 degrees Celsius, resulting in a waste of heat energy. Therefore, this invention proposes an LED light circuit board with a simple structure that transfers the heat of the circuit board to the incense chamber through a heat-conducting plate, thereby achieving heat dissipation of the circuit board and utilization of the heat. Summary of the Invention

[0027] See Figure 1-3An LED lamp circuit board includes a circuit board body 1, an upper heat-conducting plate 7, a lower heat-conducting plate 16, and an aroma chamber 26. Electronic components 2 are mounted on the circuit board body 1. An LED lamp tube 3 is fixedly mounted on the circuit board body 1, and a light-emitting semiconductor 4 is mounted on the LED lamp tube 3. A through mounting hole 5 is provided on the circuit board body 1, through which the circuit board body 1 is installed inside the LED lamp housing. The upper heat-conducting plate 7 is located above the circuit board body 1, and an upwardly recessed support shell 8 is provided on the upper heat-conducting plate 7. The shape of the support shell 8 matches the shape of the electronic component 2 protruding from the circuit board body 1. A connecting piece 34 is fixedly mounted inside the support shell 8, and the connecting piece 34 connects to the electronic component 2. The heat source of component 2 is in contact with the heat source of the LED tube 3. The heat is transferred to the upper heat-conducting plate 7 through the connecting piece 34. The upper heat-conducting plate 7 is fixedly provided with a tube housing 9 opposite to the LED tube 3. The upper end of the tube housing 9 is provided with an opening 10. The tube housing 9 is in contact with the outer wall of the LED tube 3. The opening 10 corresponds to the light-emitting semiconductor 4, so that the tube housing 9 can transfer the heat around the LED tube 3 without affecting the light emission of the light-emitting semiconductor 4.

When the mounting groove 17 and the insertion bracket 13 are combined, the top of the mounting groove 17 rests on the circuit board body 1, thereby fixing the upper heat conduction plate 7 and the lower heat conduction plate 16 on the circuit board body 1. The connecting plate 11 extends to both sides of the circuit board body 1 and is fixedly provided with insertion plates 15. The lower heat conduction plate 16 is fixedly provided with upward-opening insertion grooves 18 on the front and rear sides corresponding to the insertion plates 15. The insertion plates 15 and the insertion grooves 18 are slidably connected. The heat of the upper heat conduction plate 7 is transferred to the lower heat conduction plate 16 through the combined insertion plates 15 and insertion grooves 18.

[0029] See Figure 1-3 A fixing plate 19 is fixedly provided at the bottom of the lower heat-conducting plate 16. A uniformly arranged partition grid 20 composed of heat-conducting plates is fixedly provided on one side of the fixing plate 19. The upper end of the partition grid 20 is fixedly connected to the lower heat-conducting plate 16. Heat is transferred through the partition grid 20. A uniformly arranged sliding chamber 27 is provided on the incense chamber 26. The partition grid 20 and the sliding chamber 27 are slidably connected at intervals, so that the partition grid 20 can fully input heat into the sliding chamber 27, thereby heating the incense chamber 26.

[0030] See Figure 1-3 The fixed plate 19 is fixed with sliding rails 22 on both sides and with a pad 23 fixed at the other end. A sliding frame 21 is slidably mounted inside the sliding rails 22. The sliding rails 22 keep the sliding frame 21 stable during sliding. The sliding frame 21 is fixed with evenly arranged ejector columns 33 on one side of the fixed plate 19. The ejector columns 33 extend through the fixed plate 19 and into the space between the partition grids 20. The ejector columns 33 push the sliding chamber 27 outward from between the partition grids 20. The sliding frame 21 is fixed with symmetrical sliding columns 24 on one side of the pad 23. The sliding columns 24 extend through the pad 23. A compression spring 25 is fitted on the sliding column 24 between the pad 23 and the sliding frame 21. The compression spring 25 pushes the sliding frame 21.

[0031] See Figure 3 Connecting rods 37 are slidably provided on both sides of the inner wall of the incense chamber 26. A cleaning plate 36 is fixedly provided on the inner wall of the incense chamber 26 near the top column 33. The cleaning plate 36 scrapes out the dregs in the incense chamber 26. The cleaning plate 36 covers the inner wall of the incense chamber 26 and is connected to it. The other end of the connecting rod 37 extends to the opening of the incense chamber 26 and is fixedly provided with a pull rod 38. By pulling the protruding pull rod 38, the cleaning plate 36 is driven to move forward. The incense chamber 26 is filled with incense 35. The incense 35 should be a type of incense with a suitable heating temperature of 40 degrees to 65 degrees.

[0032] See Figure 1-2 The opening of the incense chamber 26 is equipped with an opening and closing door 28 via a pivot. The opening and closing door 28 has a through mesh 29 through which the volatile substances of the incense 35 are directly discharged to the outside. When the opening and closing door 28 is closed, the front end extends out of the incense chamber 26. A hook 30 is fixedly provided on the inner side of the front end of the opening and closing door 28. The hook 30 is detachably connected to the LED lamp housing by a buckle. The hook 30 is fastened to the LED lamp housing to fix the incense chamber 26 inside the LED lamp housing. The outer side of the opening and closing door 28 has a buckle groove 31. Activating the buckle groove 31 disengages the hook 30 from the buckle groove of the LED lamp housing. When the opening and closing door 28 is connected to the LED lamp housing by the buckle, its outer side is on the same plane as the LED lamp housing. The compression spring 25 is compressed, so that the incense chamber 26 is fully inserted into the LED lamp housing, which can absorb heat and prevent scratches.

[0033] The LED circuit board of the present invention has a simple structure. The heat of the circuit board is transferred to the incense chamber through a heat-conducting plate. While transferring heat to the circuit board, the normal use of the circuit components is not affected. It realizes heat dissipation of the circuit board and utilization of heat at the same time, and is suitable for widespread application.

[0034] For specific usage, please refer to... Figure 1-5When installing the circuit board, the upper heat-conducting plate 7 is placed above the circuit board body 1, and the lower heat-conducting plate 16 is placed above the circuit board body 1. The fixing bracket 12 passes through the through hole 6, and the insertion bracket 13 is inserted into the mounting slot 17 and fixed by the mounting screw 32. At this time, the upper end of the mounting slot 17 is against the circuit board body 1. The bearing shell 8 contacts the heat-generating part of the circuit element through the connecting piece 34 and transfers the heat to the upper heat-conducting plate 7. The insertion plate 15 is connected to the insertion slot 18 and transfers the heat to the lower heat-conducting plate 16. The lower heat-conducting plate 16 then transfers the heat to the partition grid 20.

[0035] See Figure 2-3 The sliding chamber 27 on the incense chamber 26 is inserted between the partition grids 20, and the incense chamber 26 is heated through the partition grids 20. Incense 35 is placed in the incense chamber 26. Heating the incense 35 can accelerate the volatilization effect of the incense 35. When the incense 35 needs to be replaced, the cleaning plate 36 is pulled forward by pulling the lever 38 to remove the dregs from the incense chamber 26 and replace the incense 35.

[0036] See Figure 1 , 3 When the incense chamber 26 is inserted into the gap of the partition 20, the compression spring 25 is compressed. When the incense chamber 26 is installed, the hook 30 is locked onto the LED light housing, fixing the incense chamber 26 onto the partition 20. The volatiles of the incense 35 are discharged to the outside through the mesh 29. When the incense chamber 26 needs to be removed, the hook 30 is pulled out from the LED light housing through the latch 31. After the opening and closing door 28 is opened, the sliding frame 21 is pushed forward along the sliding track 22 by the compression spring 25, pushing the ejector column 33 forward, causing the incense chamber 26 to pop out from the partition 20.
