Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, and more specifically, to an LED plastic-coated aluminum heat dissipation structure. Background Art

[0002] LED is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.

[0003] Due to the advantages of LED lamps such as simple structure, low cost and high technological maturity, they are widely used in the field of lighting. In order to prevent LED light from directly entering the human eye and causing glare, most existing LED lamps are often equipped with lampshades, and the lampshades can also protect and decorate the LED lamps. However, due to the small size of the LED light-emitting body, the heat is concentrated. Most existing LED lampshades often do not have a heat dissipation function, which often causes the temperature of the LED to be too high during lighting, resulting in serious light decay and affecting the service life. Therefore, they need to be improved. Utility Model Content

DETAILED DESCRIPTION

[0029] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, the utility model provides an LED plastic-coated aluminum heat dissipation structure, including:

[0031] An upper lampshade 1 is provided with a vertical groove 2 on its outer surface, a connecting ring 3 is movably sleeved inside the upper lampshade 1, and a lower lampshade 4 is fixedly mounted on the bottom end of the connecting ring 3;

[0032] The heat dissipation mechanism is arranged inside the upper lampshade 1;

[0033] The heat dissipation mechanism includes a heat dissipation layer 10 . The heat dissipation layer 10 is arranged inside the upper lampshade 1 and is made of aluminum.

[0034] Since the heat dissipation layer 10 is made of aluminum, the heat dissipation layer 10 has an excellent heat absorption function, and can absorb and conduct the heat inside the upper lampshade 1, thereby achieving a good heat dissipation effect.

[0035] Among them, the vertical slot 2 is internally movably connected to a moving block 5, the bottom end of the moving block 5 is fixedly installed with a short rod 6, the bottom end of the short rod 6 is hinged to a moving rod 7, the other end of the moving rod 7 is hinged to a rotating rod 8, the other end of the rotating rod 8 is hinged to the inside of the upper lampshade 1, and the outer surfaces of the moving rod 7 and the rotating rod 8 are both movably connected to the inner surface of the outer surface of the connecting ring 3.

[0036] Due to the design of the vertical slot 2, the movement of the moving block 5 will be limited so that it can only move up and down. When the moving block 5 moves upward along the inside of the vertical slot 2, the short rod 6 will move upward driven by the moving block 5, and then the short rod 6 will drive the rotating rod 8 to move through the moving rod 7. At this time, the rotating rod 8 will rotate around the hinge with the inside of the upper lampshade 1. At the same time, the two moving rods 7 will rotate around the hinge with the short rod 6 as the axis during the movement, and then the moving rod 7 and the rotating rod 8 will rotate out of the inside of the connecting ring 3, thereby releasing the lock on the entire connecting ring 3.

[0037] The top of the moving block 5 is fixedly mounted with a first spring 9 , and the top of the first spring 9 is fixedly connected to the inside of the vertical slot 2 .

[0038] Due to the design of the first spring 9 , the movement of the moving block 5 can be effectively reset.

[0039] A fixing block 11 is fixedly sleeved on the inner portion of the top of the upper lampshade 1 , a threaded sleeve 12 is fixedly sleeved on the top of the outer surface of the fixing block 11 , and an L-shaped groove 13 is provided inside the fixing block 11 .

[0040] Due to the design of the threaded sleeve 12, the upper lampshade 1 as a whole can be conveniently connected to the power supply, and due to the design of the L-shaped groove 13, the object located therein can be limited.

[0041] A circular plate 14 is movably sleeved inside the connecting ring 3 , and a lamp bead 15 is fixedly mounted on the bottom end of the circular plate 14 .

[0042] When the lamp bead 15 is connected to the power supply, the lamp bead 15 will illuminate.

[0043] Among them, a connecting block 16 is fixedly installed on the top of the circular plate 14, and the top of the outer surface of the connecting block 16 is movably connected to the inside of the fixed block 11. A conductive rod 17 is fixedly connected to the inside of the connecting block 16, and the bottom end of the conductive rod 17 is fixedly connected to the top of the circular plate 14.

[0044] When the inside of the conductive rod 17 is energized, the conductive rod 17 will transmit electrical energy to the lamp bead 15, so that the lamp bead 15 is illuminated.

[0045] The top end of the outer surface of the connecting block 16 is fixedly mounted with an arc block 18 , and the outer surface of the arc block 18 is movably connected to the inside of the L-shaped groove 13 .

[0046] Due to the limitation of the L-shaped groove 13, the arc block 18 can only move along the inside of the L-shaped groove 13. Due to the design of the shape of the L-shaped groove 13, when the top of the arc block 18 contacts the top inside the L-shaped groove 13, the L-shaped groove 13 will block the downward movement of the arc block 18.

[0047] Among them, the top of the connecting block 16 is movably connected to a round block 19, the outer surface of the round block 19 is movably sleeved with the inside of the fixed block 11, the inside of the round block 19 is fixedly sleeved with a conductive column 20, and the bottom end of the conductive column 20 is movably connected to the top of the conductive rod 17.

[0048] Since the outer surface of the round block 19 is movably connected to the inside of the fixed block 11, the round block 19 can move up and down along the inside of the fixed block 11. Due to the design of the conductive column 20, when the conductive column 20 is energized, the conductive column 20 will be able to transmit electrical energy to the inside of the conductive rod 17.

[0049] The top of the conductive column 20 is movably connected to a conductive block 22 . The outer surface of the conductive block 22 is fixedly sleeved with an insulating block 21 . The outer surface of the insulating block 21 is fixedly sleeved with the inner portion of the fixed block 11 .

[0050] Due to the design of the conductive block 22 , when the top of the conductive block 22 contacts the power source, the conductive block 22 can transmit electrical energy to the conductive column 20 .

[0051] A second spring 23 is fixedly mounted on the top of the round block 19 , and the top of the second spring 23 is fixedly connected to the bottom end of the insulating block 21 .

[0052] Due to the elastic force of the second spring 23, when the bottom end of the round block 19 is no longer blocked by the entire connecting block 16, the second spring 23 will drive the round block 19 to move downward as a whole. At this time, the conductive column 20 will lose contact with the conductive block 22 during the downward movement.

[0053] The working principle and use process of this utility model:

[0054] When the lamp bead 15 generates heat during the lighting process, due to the design of the heat dissipation layer 10, the heat emitted by the lamp bead 15 will be absorbed by the heat dissipation layer 10 and then directed to the interior of the upper lampshade 1, thereby being able to efficiently dissipate the heat of the lamp bead 15.

[0055] When the lamp bead 15 fails, the operator pulls the two moving blocks 5 at the same time. At this time, the two moving blocks 5 will move upward along the inside of the two vertical slots 2. During this process, the two first springs 9 will be in a compressed state. Due to the elastic force of the two first springs 9, the movement of the two moving blocks 5 will have a good reset effect. At the same time, the two moving blocks 5 will respectively drive the two short rods 6 to move upward. At this time, the two short rods 6 will drive the two moving rods 7 to move during the upward movement. Then, the other ends of the two moving rods 7 will respectively drive the two rotating rods 8 to move. At this time, the two rotating rods 8 will rotate around the hinge with the inside of the upper lampshade 1 as the axis. At the same time, the two moving rods 7 will rotate around the hinge with the short rods 6 as the axis during the movement. When the outer surfaces of the two moving rods 7 and the two rotating rods 8 move out of the interior of the connecting ring 3 during the rotation, the two moving rods 7 and the two rotating rods 8 will release the locking effect on the entire connecting ring 3, so that the entire connecting ring 3 can be removed from the interior of the upper lampshade 1, thereby realizing the function of convenient disassembly and assembly of the lower lampshade 4.

[0056] Then the operator twists the circular plate 14 as a whole. At this time, the circular plate 14 will drive the arc block 18 to rotate along the inside of the L-shaped groove 13 through the connecting block 16. When the arc block 18 rotates thirty degrees, the inside of the L-shaped groove 13 will release the locking effect on the entire arc block 18. Due to the elastic force of the second spring 23, the second spring 23 will drive the circular block 19 as a whole to move downward. At this time, the connecting block 16 as a whole will move downward under the push of the circular block 19 as a whole. At this time, the circular plate 14 will be able to be taken out from the inside of the upper lampshade 1. At this time, the operator will be able to replace the circular plate 14 as a whole, thereby realizing the function of being able to conveniently replace the circular plate 14 as a whole.
