[0024] like Figure 1-6As shown, an aluminum trough type COB soft lamp includes an aluminum trough 1 and a light strip 2. A supporting portion 11 for supporting the bottom of the light strip 2 is symmetrically arranged in the aluminum trough 1, and a fixing plate 3 and an unlocking plate 4 are symmetrically arranged in the aluminum trough 1. The fixing plate 3 is rotatably arranged in the aluminum trough 1, and the unlocking plate 4 is slidably arranged in the aluminum trough 1 and the first end of the unlocking plate 4 extends out of the outside of the aluminum trough 1. The fixing plate 3 is in a default state and is parallel to the supporting portion 11 to clamp the light strip 2. The unlocking plate 4 slides to drive the fixing plate 3 to rotate away from the supporting portion 11 to unlock the light strip 2.

[0025] Specifically, such as Figure 2 As shown, the upper end of the unlocking plate 4 is the first end, and the upper end of the unlocking plate 4 extends out of the outside of the aluminum groove 1, and the light strip 2 is placed on the supporting portion 11 in the aluminum groove 1, and the fixing plate 3 is parallel to the supporting portion 11 in the default state. At this time, the fixing plate 3 is in contact with the top of the light strip 2, and then the fixing plate 3 and the supporting portion 11 are used to complete the clamping and fixing of the light strip 2. When the light strip 2 in the aluminum groove 1 needs to be removed, it is only necessary to press the first end of the unlocking plate 4 to drive the unlocking plate 4 to slide. At this time, the unlocking plate 4 slides to drive the fixing plate 3 to rotate away from the supporting portion 11 to unlock the top of the light strip 2. At this time, the light strip 2 can be directly removed from the aluminum groove 1 from the front, and there is no need to disassemble the aluminum groove 1 as a whole to replace the light strip 2, thereby facilitating the disassembly and replacement of the light strip 2 in the aluminum groove 1 and improving maintenance efficiency.

[0026] Furthermore, a rotating portion 31 is symmetrically provided on the fixed plate 3, and the rotating portion 31 is rotatably provided in the aluminum groove 1. A worm spring 7 is symmetrically provided in the aluminum groove 1 for driving the rotating portion 31 to rotate so as to drive the fixed plate 3 to reset to the default state. The rotating portion 31 is rotatably provided in a rotating groove 12 opened in the aluminum groove 1, and the worm spring 7 drives the rotating portion 31 to rotate so that the fixed plate 3 is reset to the default state. The worm spring 7 is used to improve the stability of the fixed plate 3 when it remains in the default state and clamps the fixed light strip 2.

[0027] In the above technical solution, the first end of the unlocking plate 4 is pressed to drive the unlocking plate 4 to slide. At this time, the unlocking plate 4 slides to drive the fixing plate 3 to rotate away from the supporting portion 11 to unlock the top of the light strip 2. At this time, the light strip 2 can be directly removed from the aluminum groove 1 from the front. There is no need to disassemble the aluminum groove 1 as a whole to replace the light strip 2, which facilitates the disassembly and replacement of the light strip 2 in the aluminum groove 1 and improves maintenance efficiency.

[0028] As an embodiment further provided by the present invention, a linear array of sealant 21 for sealing the lamp beads is provided on the light strip 2, and a semicircular raised limiting belt 22 is symmetrically provided on the light strip 2, and an arc-shaped limiting groove 32 is provided on the fixing plate 3. The fixing plate 3 is driven to rotate close to the supporting part 11 so that the limiting belt 22 contacts the limiting groove 32, and the fixing plate 3 squeezes the limiting belt 22 so that the light strip 2 moves to the middle of the aluminum groove 1.

[0029] Specifically, such as Figure 2 As shown, the sealant 21 covers the lamp beads of the light strip 2 to achieve the packaging and protection of the lamp beads, and the limit belts 22 are symmetrically provided on the light strip 2, and the limit grooves 32 are symmetrically provided on the fixing plate 3. When the light strip 2 is installed, the light strip 2 is first placed on the supporting portion 11, and then the fixing plate 3 is rotated to reset to the default position to be close to the supporting portion 11. At this time, the limit groove 32 of the fixing plate 3 rotates close to the light strip 2 and makes the limit belt 22 contact the limit groove 32. If the light strip 2 is not in the center position in the aluminum groove 1 at this time, the limit belt 22 will contact the groove of the limit groove 32. The surface is driven by the pressure of the fixing plate 3 to move the light strip 2 until the limiting belt 22 is pressed and moves to the middle of the bottom of the limiting groove 32. At this time, the light strip 2 moves to the middle position of the aluminum groove 1 to make the sealant 21 and the lamp beads therein located in the middle of the aluminum groove 1, thereby improving the actual lighting effect of the light strip 2 when the installation is completed and reducing the obstruction of the light. The limiting groove 32 of the fixing plate 3 and the limiting belt 22 of the light strip 2 are utilized to achieve that when the light strip 2 is installed, it will be automatically centered in the aluminum groove 1 under the action of the fixing plate 3, thereby further reducing the difficulty of installation and improving the efficiency of maintenance.

[0030] As an embodiment further provided by the present invention, it also includes a translucent cover plate 5, on which a clamping portion 51 is symmetrically arranged, and a clamping groove 13 is symmetrically opened on the aluminum groove 1. The clamping portion 51 is clamped in the clamping groove 13 so that the translucent cover plate 5 covers the aluminum groove 1, and the translucent cover plate 5 is flush with the first end surface of the unlocking plate 4.

[0031] Specifically, such as Figure 2 As shown, the light-transmitting cover plate 5 is fixed on the aluminum groove 1 by the clamping portion 51 and the clamping groove 13 to block it, thereby further protecting the light strip 2 and improving the service life of the light strip 2. At this time, the first end face of the unlocking plate 4 is flush with the light-transmitting cover plate 5, and the unlocking plate 4 blocks both sides of the light-transmitting cover plate 5, and then uses the unlocking plate 4 to protect the light-transmitting cover plate 5, avoids the problem that the side of the light-transmitting cover plate 5 is hit and detached, and improves the use stability of the light-transmitting cover plate 5. Secondly, the unlocking plate 4 blocks the side of the light-transmitting cover plate 5 to avoid the lateral light leakage problem of the light-transmitting cover plate 5, improves the heat dissipation uniformity of the light emitted by the light strip 2 after passing through the light-transmitting cover plate 5, and improves the lighting effect.

[0032] As an embodiment further provided by the present invention, the unlocking plate 4 is slidably arranged in the sliding groove 14 opened on the aluminum groove 1, and the unlocking plate 4 is provided with an unlocking portion 41 and a pushing portion 42. The pushing portion 42 is located in the clamping groove 13. The unlocking plate 4 is driven to slide so that the unlocking portion 41 pushes the first end of the fixed plate 3 to drive the fixed plate 3 to rotate away from the supporting portion 11, and the pushing portion 42 slides to push the clamping portion 51 out of the clamping groove 13.

[0033] Specifically, such as Figure 2As shown, the unlocking plate 4 is slidably disposed in the sliding groove 14, and the push portion 42 of the unlocking plate 4 is located in the clamping groove 13. Figure 2 As shown, the end of the fixing plate 3 facing away from the light strip 2 is the first end, and the unlocking portion 41 extends above the first end of the fixing plate 3. When the unlocking plate 4 is pressed to slide, the unlocking portion 41 moves to push one end of the fixing plate 3, thereby driving the fixing plate 3 to flip away from the supporting portion 11 to unlock the light strip 2, and the pushing portion 42 slides to push the clamping portion 51 out of the clamping groove 13 to unlock the light-transmitting cover plate 5, thereby unlocking and removing the light-transmitting cover plate 5 and the light strip 2 at the same time, further improving the disassembly efficiency.

[0034] Furthermore, a spring 6 is provided in the sliding groove 14 to drive the unlocking plate 4 to slide and reset. The spring 6 moves to push the unlocking plate 4 to slide so that the unlocking portion 41 no longer applies pressure to the first end of the fixed plate 3, thereby completing the reset of the unlocking plate 4 and facilitating the reset of the fixed plate 3, thereby improving the overall operating stability.

[0035] As a further embodiment provided by the present invention, an airbag 8 is fixedly provided on the fixing plate 3 at the bottom of the limiting groove 32 , and a linear array of ejection holes 33 facing the sealant 21 is opened on the fixing plate 3 , and the ejection holes 33 are connected to the airbag 8 .

[0036] Specifically, such as Figure 6 As shown, the airbag 8 is arranged at the bottom of the limiting groove 32, and the airbag 8 is connected to the ejection hole 33. When the light strip 2 in the aluminum groove 1 is used for a long time, dust will inevitably accumulate on the aluminum groove 1 and the sealant 21 of the light strip 2, and the presence of dust will reduce the light intensity of the light strip 2. At this time, the unlocking plate 4 can be pressed to slide so that the fixing plate 3 is first flipped away from the supporting part 11. At this time, the airbag 8 is reset due to its own elastic deformation and expands in volume, and the pushing part 42 pushes the clamping part 51 to unlock the light-transmitting cover plate 5. Then, the light-transmitting cover plate 5 is removed and the unlocking plate 4 is released. At this time, the unlocking plate 4 is driven by the spring 6 to slide The air bag 8 and the ejection hole 33 on the fixed plate 3 are used to clean the dust inside the aluminum groove 1 and on the light strip 2, thereby avoiding the problem of reduced light intensity emitted by the light strip 2 due to dust obstruction, improving the durability of the light strip 2 and facilitating the cleaning and maintenance of the light strip 2.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
