Description

Technical Field

[0001] The utility model belongs to the technical field of LED lamps, and particularly relates to an LED lamp facilitating the replacement of a lamp strip. Background Art

[0002] LEDs have the characteristics of energy conservation, environmental protection, long service life, small volume, etc., and are widely used in the lighting field. For example, indoor entertainment lighting, building advertising lighting, and contour display all adopt LED lighting devices. Especially for LED tubes, in the prior art, the LED lamp strips inside the tubes are often fixed in the inner cavity of the lamp cover by bolts or glue. Moreover, since the end caps at both ends of the tube are often fixed to the lamp cover body by a locking method, the LED tube becomes a disposable item. In order to change this wasteful situation, some LED tubes can replace the lamp strip in the inner cavity of the lamp cover.

[0003] For example, the Chinese patent with the publication number CN216591128U discloses an LED lamp facilitating the replacement of a lamp strip, which includes a housing. A lamp strip is slidably connected to the top end inside the housing. Plug-in slots are provided at both ends of the lamp strip. End caps are symmetrically provided at both ends of the housing. One side of the end cap facing the port of the housing is provided with a plug-in head, and the plug-in head and the plug-in slot are plugged together. The end cap and the housing are plugged together. The utility model solves the problem that the lamp strip installed inside the existing LED tube is difficult to disassemble and replace, resulting in only being able to directly replace the entire LED tube when the lamp strip inside the LED tube is damaged, leading to a large amount of resource waste. By improving and optimizing the structure of the LED tube, the lamp strip inside the LED tube can be conveniently and quickly installed and disassembled, facilitating the rapid replacement of the lamp strip when the lamp strip is damaged. Moreover, the LED tube with this structure is convenient to assemble, facilitating the staff to quickly install and use, and effectively improving the use flexibility of the LED tube.

[0004] This patent has some disadvantages in use. For example, the device in this patent is fixed by plugging and installing the end cap and the housing. However, the lamp strip structure in this device is relatively special, and it needs to be cooperated with a specific plug-in head and the plug-in slot in the lamp strip to complete power-on. Compared with the relatively common LED lamp strips in the market, the applicability of this device is lower. In addition, when the end cap in this device is damaged, the entire end cap body needs to be replaced, and the overall cost is relatively high. In view of this, we propose an LED lamp facilitating the replacement of a lamp strip. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide an LED lamp facilitating the replacement of a lamp strip to solve the problems raised in the above background art.

[0006] In view of this, the present utility model provides an LED lamp facilitating the replacement of a lamp strip, including:

[0007] A fixing plate, on the front side of which there are lamp shades of equal length. The cross-section of the fixing plate and the lamp shade forms a circular structure.

The two conductive copper tubes are respectively electrically connected to the positive and negative electrodes on the lamp strip.

[0011] In the above technical solution, further, the fixing component includes:

[0012] Four clamping blocks are evenly distributed in a circumferential manner and are all fixedly installed in the inner groove of the chuck. The clamping blocks are in an inverted hook structure. Through holes adapted to the four clamping blocks are opened on the connecting cover. One end of the clamping block passes through the through hole on the connecting cover and is clamped and fixed with the inner side wall close to the through hole.

[0013] In the above technical solution, further, the clamping block has elasticity, and the chuck and the four clamping blocks are of an integrally formed structure.

[0014] In the above technical solution, further, the limiting component includes:

[0015] A plurality of limiting holes are opened on the outer side wall of the connecting cover, and the plurality of limiting holes are distributed in a semi-circular shape. Limiting blocks are fixed at positions on the outer wall of the connecting cover close to the two end limiting holes at the end. A sliding groove is opened on the side wall of the chuck. A sliding piece is slidably installed in the sliding groove. The outer part of the sliding piece is in a semi-circular arc structure, and the inner part of the sliding piece is in a cylindrical structure. A spring is installed at the inner side position inside the sliding piece in the sliding groove. The two ends of the spring are respectively fixed with the inner wall of the sliding groove and the side wall of the cylindrical end inside the sliding piece. The cylindrical end inside the sliding piece is inserted and matched with the limiting hole.

[0016] In the above technical solution, further, anti-slip patterns are provided on the outer wall at the outer position of the sliding piece.

[0017] In the above technical solution, further, a plurality of heat dissipation holes are provided at equal circumferential intervals on the side wall of the chuck.

[0018] In the above technical solution, further, an annular groove is provided at one end of the conductive copper tube located inside.

[0040] Two groups of limiting components are respectively arranged on two chucks 6 and are used to control the rotation angle of the chuck 6 on the connecting cover 5;

[0041] Mounting holes 14 are symmetrically formed in the chuck 6. A copper pin 15 is inserted and mounted in the mounting hole 14. A conductive copper tube 16 is inserted and mounted on the side of the copper pin 15 close to the connecting cover 5. One end of the conductive copper tube 16 extends into the end cover 4. The two conductive copper tubes 16 are respectively electrically connected to the positive and negative electrodes on the lamp strip 3;

[0042] In this embodiment, the fixing component includes:

[0043] Four clamping blocks 7 are arranged at equal circumferential intervals and are fixedly mounted in the inner groove of the chuck 6. The clamping block 7 has an inverted hook-shaped structure. Through holes 8 adapted to the four clamping blocks 7 are formed in the connecting cover 5. One end of the clamping block 7 passes through the through hole 8 in the connecting cover 5 and is fixedly clamped with the inner side wall close to the through hole 8;

[0044] In this embodiment, the limiting component includes:

[0045] A plurality of limiting holes 9 are formed in the outer side wall of the connecting cover 5, and the plurality of limiting holes 9 are distributed in a semicircular shape. Limiting blocks 10 are fixed at positions on the outer wall of the connecting cover 5 close to the two limiting holes 9 at the ends. A sliding groove 11 is formed in the side wall of the chuck 6.

The cylindrical end inside the sliding piece 12 is inserted and matched with the limiting hole 9.

[0046] Among them, the working principle of this device is as follows:

[0047] During installation, first insert the light bar 3 into the card slot 18 on the fixed plate 1. When inserting, pay attention to the force magnitude and insertion angle to avoid phenomena such as oblique insertion and incorrect insertion, reducing the adverse effects on the light bar 3. After slowly feeding the light bar 3 into the card slot 18, close the lamp cover 2 and the fixed plate 1. Then hold the end head mechanism. First, wind the connecting wires on the light bar 3 around the conductive copper tubes 16 in the end head mechanism respectively. Then hold the end cover 4 and send it towards one end of the fixed plate 1 and the lamp cover 2, so that one end of the fixed plate 1 and the lamp cover 2 is inserted into the inner cavity of the end cover 4. Similarly, insert another end head mechanism into the other end of the fixed plate 1 and the lamp cover 2; compared with the prior art, this device can meet most of the LED light bars in the market, has a wide application range, and changes the disadvantage of "specific lamp for specific use" in the traditional device. By winding and connecting the connecting wires on the light bar 3 with the conductive copper tubes 16, the overall connection is relatively simple, facilitating non-professional maintenance personnel to install and avoiding the need for professional equipment for connection;

[0048] When the light bar 3 needs to be replaced, the method is the same as above. Just pull the end cover 4 outwards to disconnect the end cover 4 from the fixed plate 1 and the lamp cover 2, and then untie the connecting wires between the light bar 3 and the corresponding conductive copper tubes 16 respectively;

[0049] Since the copper pin 15 is a vulnerable part, when the copper pin 15 needs to be replaced, first pull out the end head mechanism from one end of the fixed plate 1 and the lamp cover 2, and then push the copper pin 15 forcefully from the outside to the inside, and the copper pin 15 can be pushed out of the installation hole 14. It should be noted that an anti-slip collar is provided at the position of the copper pin 15 close to the installation hole 14, which has a certain elasticity and can prevent the outer end of the copper pin 15 from slipping out. After replacing the copper pin 15, then operate in the reverse order of the above steps to reinstall the new copper pin 15. There is an interference fit between the copper pin 15 and the conductive copper tube 16. Since the copper pin 15 has a certain toughness and elasticity, when not under external force, the conductive copper tube 16 can be firmly clamped inside the copper pin 15.
