[0031] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0032] The following is combined with Figures 1-6 This embodiment is described in further detail.

[0033] like Figure 1-6 As shown, in this embodiment, an LED lamp tube with a reflector includes a first shell 100 and a lamp head 110. The first shell 100 is provided with a lamp board 200, and LED lamp beads are evenly distributed on the lamp board 200. The first shell 100 is also provided with a detachable second shell 120. A support plate 210 is provided on the upper end surface of the first shell 100, and a slidable reflector 220 is provided on the support plate 210. The lamp board 200 is fixedly installed on the upper end surface of the reflector 220. The upper end surface of the support plate 210 and on both sides are further provided with relative vertical plates 211. The opposite side walls of the vertical plates 211 are provided with limiting plates 212 for limiting the reflector 220. Limiting components for limiting the sliding of the reflector 220 are provided at both ends of the support plate 210.

[0034] In this embodiment, the first shell 100 is arc-shaped, and the second shell 120 is also arc-shaped. The second shell 120 is mounted on the first shell 100 to form a tubular structure. The support plate 210 is arranged along the extension direction of the first shell 100, and its two ends are integrally formed on the inner wall of the first shell 100 to form a hollow first shell 100. The vertical plate 211 is arranged along the extension direction of the support plate 210, and the limiting plate 212 extends along the extension direction of the support plate 210 toward the inside of the first shell 100 to form an inner slot for engaging the reflective plate 220.

[0035] The light board 200 is fixedly mounted on the upper end surface of the reflector 220 by gluing. Then, the reflector 220 is slid onto the support plate 210 from one end of the support plate 210, so that both sides of the reflector 220 are located in the corresponding inner grooves, thereby realizing the plug-in installation of the reflector 220 and the light board 200 as a whole on the first shell 100. At this time, the sliding reflector 220 is limited by the limiting components at both ends of the support plate 210, so that the positions of the reflector 220 and the light board 200 on the support plate 210 are fixed. Then, the second shell 120 is installed on the first shell 100. When the installation of the second shell 120 on the first shell 100 is completed, the first shell 100 and the second shell 120 form the lamp tube body. Finally, the two lamp heads 110 are electrically connected to the lamp board 200, and the lamp heads 110 are respectively sleeved on the two ends of the lamp tube body by interference fit.

[0036] In this embodiment, the sliding reflector 220 is limited by the limiting assembly on the support plate 210, so that the positions of the reflector 220 and the light board 200 on the support plate 210 are fixed. Compared with the existing LED tube with a reflector, this can prevent the reflector 220 from causing the light board 200 to shake back and forth on the support plate 210 during actual use, thereby preventing damage to the light board 200.

[0037] The second housing 120 is made of a transparent material, so that the light emitted by the LED lamp beads on the light board 200 can pass through the second housing 120 for illumination; the reflector 220 facing the side of the light board 200 can reflect the light reflected from the light board 200 back to the second housing 120, thereby ensuring that the light emitted by the LED lamp beads on the light board 200 can better pass through the second housing 120, thereby improving the utilization rate of light;

[0038] Specifically, the first housing 100, the support plate 210, and the reflector 220 are all made of aluminum. When the reflector 220 is snap-fitted and mounted on the support plate 210, it fits the support plate 210. As a result, the heat generated by the lamp board 200 and the LED lamp beads during operation can be transferred from the support plate 210 to the first housing 100, dissipating the heat. This can provide a certain degree of heat dissipation for the lamp board 200 and the LED lamp beads.

[0039] In actual use, in order to better realize the disassembly and assembly of the second shell 120 on the first shell 100, the sides of the vertical plates 211 that are away from each other are provided with snap-in grooves 213 along the extension direction of the support plate 210, and the two sides of the second shell 120 are bent to form snap-in parts 600. The snap-in parts 600 on the second shell 120 are inserted into the corresponding snap-in grooves 213 through interference fit, so that the second shell 120 is installed on the vertical plate 211, that is, the disassembly and assembly of the second shell 120 on the first shell 100 is realized.

[0040] like Figure 1-3 As shown, in this embodiment, grooves 301 are formed at both ends of the support plate 210;

[0041] The limiting assembly includes positioning plates 230 arranged at both ends of the support plate 210, and the positioning plates 230 are each provided with an insert plate 310 with one end inserted into the corresponding groove 301. A relative horizontal plate 240 is provided in the first shell 100 and below the support plate 210, and a positioning member is provided on the lower end surface of the horizontal plate 240 for positioning the position of the insert plate 310.

[0042] In this embodiment, the groove 301, the positioning plate 230, the inserting plate 310, the horizontal plate 240 and the positioning member are arranged so that the inserting plate 310 is fixedly mounted on the positioning plate 230. When the two inserting plates 310 are inserted into the corresponding grooves 301, the two positioning plates 230 respectively abut against the corresponding ends of the reflector 220. At this time, the position of the inserting plate 310 is positioned by the positioning member on the horizontal plate 240, so that the reflector 220 can be limited on the support plate 210, thereby preventing the reflector 220 from causing the light board 200 to shake along the support plate 210.

[0043] During actual use, the lamp head 110 is disassembled from one end of the lamp tube body, and the positioning piece releases the positioning of the plug-in board 310. By sliding the plug-in board 310 out of the groove 301, the positioning plate 230 releases the contact with the reflector 220. At this time, the limit on the reflector 220 is released, so that the reflector 220 can drive the lamp board 200 to slide out from one end of the lamp tube body, thereby facilitating the staff to inspect and repair the lamp board 200.

[0044] Specifically, in order to realize the disassembly and assembly of the horizontal plate 240 in the first shell 100, in this embodiment, a relative fixed plate 280 is fixedly installed on the inner side wall of the first shell 100 along its extension direction, and the two ends of the horizontal plate 240 are respectively overlapped on the corresponding fixed plates 280, and the horizontal plate 240 is fixed to the fixed plate 280 by bolts, thereby realizing the disassembly and assembly of the horizontal plate 240 in the first shell 100.

[0045] like Figure 1-6 As shown, in this embodiment, a mounting plate 250 is provided on the lower end surface of the horizontal plate 240 , and the lower end of the mounting plate 250 is bent to form a bent portion 251 ;

[0046] The positioning member includes a protruding rod 270 fixed on the bent portion 251, and a liftable sleeve 401 is sleeved on the protruding rod 270. The lower end of the sleeve 401 extends outward to form a circular plate 400. The protruding rod 270 is sleeved with a spring 260 for driving the upper end of the sleeve 401 to pass through the mounting plate 250 and insert into the insert plate 310.

[0047] In this embodiment, the mounting plate 250, the bent portion 251, the circular plate 400, the sleeve 401, the protruding rod 270 and the spring 260 are arranged so that the mounting plate 250 is fixedly mounted on the horizontal plate 240, the sleeve 401 is fixedly mounted on the circular plate 400, and the protruding rod 270 is fixedly mounted on the bent portion 251. When the spring 260 on the protruding rod 270 pushes the circular plate 400 upward, the circular plate 400 drives the sleeve 401 upward. At this time, the upper end of the sleeve 401 penetrates the mounting plate 250 and is inserted into the corresponding plug-in plate 310, thereby positioning the plug-in plate 310.

[0048] Among them, the upper end of the sleeve 401 slides out from the corresponding plug plate 310 to release the positioning of the plug plate 310. In order to facilitate the downward movement of the sleeve 401, the outer sleeve of the sleeve 401 is provided with a driving plate 410 overlapped on the circular plate 400, and a driving groove 411 is provided on the side wall at one end of the driving plate 410. The driving groove 411 facilitates the downward movement of the driving plate 410. The downward movement of the driving plate 410 can drive the upper end of the sleeve 401 to slide out from the corresponding plug plate 310 through the circular plate 400, thereby releasing the positioning of the plug plate 310.

[0049] In actual use, in order to ensure that the upper end of the sleeve 401 always remains in a state of sliding out of the inserting plate 310, a slot is provided on one side wall of the driving plate 410;

[0050] A block 420 that can be inserted into a slot is provided on the side of the mounting plate 250 facing the driving plate 410 along the height direction of the mounting plate 250. The driving plate 410 moves downward and rotates so that the upper end surface of the driving plate 410 abuts against the lower end surface of the block 420, thereby locking the position of the driving plate 410 after it moves downward.

[0051] In this embodiment, the card slot and the card block 420 are provided so that the card block 420 is fixedly mounted on the mounting plate 250. When the driving plate 410 moves downward, the card block 420 limits the driving plate 410 through the card slot. When the driving plate 410 moves downward to a certain distance, the card slot on the driving plate 410 and the card block 420 are disengaged. At this time, the driving plate 410 is rotated so that the upper end surface of the driving plate 410 abuts against the upper end surface of the card block 420, thereby achieving the positioning of the downward movement of the driving plate 410.

[0052] In actual use, when the drive plate 410 needs to be unlocked, the drive plate 410 is rotated so that the groove 301 on the drive plate 410 cooperates with the block 420 , thereby unlocking the drive plate 410 .

[0053] Working principle: First, slide the reflector 220 from one end of the support plate 210 onto the support plate 210, then, push the drive plate 410 downward through the drive slot 411, and rotate the drive plate 410 so that the upper end surface of the drive plate 410 abuts against the block 420. At this time, insert the insert plate 310 into the groove 301 so that the positioning plate 230 abuts against the corresponding end of the reflector 220, and then, rotate the drive plate 410 to release the drive plate 410. When the plate 410 is locked, the spring 260 will drive the sleeve 401 to be inserted into the plug plate 310, positioning the plug plate 310, and realizing the limitation of the reflector 220 and the lamp board 200 on the support plate 210. At this time, the second shell 120 is clamped into the clamping groove 213 through the clamping part 600. Finally, the two lamp heads 110 are electrically connected to the lamp board 200, and the lamp heads 110 are respectively mounted on the two ends of the lamp tube body through interference fit.

[0054] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
