[0040] Embodiment 1:

[0041] The composite light bar shell of the LED light bar provided in this embodiment is applied to the LED light bar to protect the LED lamp 70. In this embodiment, the structure of the composite light bar shell of the LED light bar is optimized to further improve its sealing performance.

[0042] like Figure 1 and Figure 2 As shown, the composite light bar shell of the LED light bar in this embodiment includes two side shell parts 10 arranged opposite to each other, and a mounting groove 101 is opened on the side of the two side shell parts 10 facing each other; the composite light bar shell of the LED light bar also includes a lamp holder 20, a lamp cover 30 and a cushion 40.

[0043] One end of the lamp holder 20 and one end of the lamp shade 30 are inserted into one mounting groove 101, and the other end of the lamp holder 20 and the other end of the lamp shade 30 are inserted into another mounting groove 101; it can be understood that during installation, one end of the lamp holder 20 and one end of the lamp shade 30 can be inserted into the mounting groove 101 of one side shell 10, and then the other side shell 10 is sleeved outside the other end of the lamp holder 20 and the other end of the lamp shade 30, thereby, the lamp holder 20 is covered by the lamp shade 30, and the ends of the lamp shade 30 are sealed by the side shells 10 on both sides. Among them, the lamp shade 30 is covered outside the lamp holder 20, and there is a gap between the lamp shade 30 and the groove wall of the mounting groove 101. Due to the setting of the gap, it is convenient for the side shell 10 to be sleeved outside the lamp shade 30 and the lamp holder 20; the cushion 40 is inserted between the lamp shade 30 and the groove wall of the mounting groove 101, so that the lamp shade 30 fits the groove wall of the mounting groove 101.

[0044] Specifically, when installing the composite light bar shell of the LED light bar, first insert one end of the lamp holder 20 and one end of the lamp shade 30 into the mounting groove 101 of one side shell portion 10, and then sleeve the mounting groove 101 of the other side shell portion 10 over the other end of the lamp holder 20 and the other end of the lamp shade 30, so that the lamp shade 30 can be initially covered outside the lamp holder 20; then, insert the gasket 40 between the lamp shade 30 and the groove wall of the mounting groove 101, at this time, the lamp shade 30 is tightly fitted with the groove wall of the mounting groove 101, so that the sealing is improved. As for the sealing of the lampshade 30, the lampshade 30 is arranged outside the lamp holder 20, and the two ends are respectively inserted into the mounting grooves 101 of the side shell 10, and the gasket 40 is used to make the lampshade 30 fit against the groove wall of the mounting groove 101, so that the end of the lampshade 30 fits tightly against the groove wall of the mounting groove 101. At this time, the side shell 10 plays a role in sealing the gap between the lampshade 30 and the lamp holder 20, reducing the risk of dust entering the interior of the lampshade 30 from the end of the lampshade 30, thereby improving the overall sealing of the LED light strip.

[0045] like Figure 3 and Figure 4 As shown, the outer wall profile of the lampshade 30 matches the notch profile of the mounting groove 101; the lampshade 30 is formed with a housing groove 301, and the lamp holder 20 is at least partially located in the housing groove 301. The lampshade 30 protects the lamp holder 20 by covering the lamp holder 20 with the housing groove 301, and the matching of the profile of the lampshade 30 and the mounting groove 101 means that the gap between the lampshade 30 and the lamp holder 20 can be covered by the side shell 10, and the gasket 40 is matched, so that the lampshade 30 can fit the groove wall of the mounting groove 101, thereby improving the sealing of the LED light bar.

[0046] Furthermore, if Figure 3 and Figure 4 As shown, the mounting groove 101 includes an arched groove 102 and a strip groove 103 which are connected to each other; the lampshade 30 includes an arched cover portion 302 which is correspondingly inserted in the arched groove 102 and a strip cover portion 303 which is correspondingly inserted in the strip groove 103; wherein, the height of the strip cover portion 303 is less than the depth of the strip groove 103, and the difference between the height and the depth is the gap for the cushion 40 to be inserted.

[0047] Furthermore, a receiving groove 201 is formed on one side of the lamp holder 20 facing the arched cover portion 302; the lamp holder 20 has a side rib 21 protruding from the back of the groove side wall of the receiving groove 201, and a bottom rib 22 protruding from the back of the groove bottom wall of the receiving groove 201; the side rib 21 abuts against the groove wall of the cover groove 301, and a gap is left between the bottom rib 22 and the groove wall of the installation groove 101. The provision of the side rib 21 and the bottom rib 22 helps the lamp holder 20 to dissipate heat, and the provision of the ribs allows the ribs to contact the lampshade 30, further improving the sealing performance.

[0048] In this embodiment, the side ribs 21 include a first rib 211 abutting against the arched cover portion 302 , and a second rib 212 abutting against the strip-shaped cover portion 303 ; wherein the second rib 212 is horizontally arranged, and the first rib 211 is inclined relative to the second rib 212 .

[0049] In this embodiment, the bottom rib 22 includes a third rib 221 at both ends and a fourth rib 222 between the two third ribs 221 ; wherein the fourth rib 222 is vertically arranged, and the third rib 221 protrudes from the fourth rib 222 and is inclined relative to the fourth rib 222 .

[0050] On the basis of the above embodiment, an insertion gap 23 is formed between adjacent side ribs 21 and bottom ribs 22; that is, an insertion gap 23 is formed between the second rib 212 and the third rib 221. The cushion member 40 includes a cushion body 401 and a protrusion 402 protruding from the cushion body 401. The cushion body 401 is disposed between the groove bottom wall of the strip groove 103 and the strip cover portion 303, and the protrusion 402 extends into the insertion gap 23. By setting the cushion 40, on the one hand, the lampshade 30 is padded up, so that the arched cover part 302 of the lampshade 30 fits with the groove wall of the arched groove 102, thereby improving the sealing of the lampshade 30, and at the same time, the raised part 402 can extend into the insertion gap 23, which means that when installing, the raised part 402 can be extended into the insertion gap 23 first, and then the cushion 40 is slowly pushed so that the cushion 40 is pushed into the installation groove 101, and then the lampshade 30 is padded up, so that the lampshade 30 fits with the groove wall of the installation groove 101, which has the advantages of convenient installation and high installation stability. At the same time, the setting of the cushion 40, especially the raised part 402, can directly contact the lamp holder 20, play a role in auxiliary heat dissipation, thereby improving the heat dissipation capacity of the composite light bar shell.

[0051] like Figure 3 and Figure 5 As shown, a first reflector 51 is installed on the top wall of the mounting groove 101, and a second reflector 52 is provided on the lamp holder 20 at the light emitting side corresponding to the first reflector 51. It can be understood that the light emitted by the LED lamp 70 at the edge can be reflected by the first reflector 51 and the second reflector 52 in sequence, and emitted from the lampshade 30 to the outside, which effectively improves the light utilization rate of the LED light strip.

[0052] like Figure 3 and Figure 5 As shown, the top wall of the mounting groove 101 is provided with a buckle portion 61, and the lampshade 30 is provided with a buckle slot 62 at a position corresponding to the buckle portion 61. The buckle portion 61 can be located outside the mounting groove 101 or inside the mounting groove 101, which is not limited in this embodiment; when the buckle portion 61 is located in the mounting groove 101, the sealing of the LED light bar can be further improved. It can be understood that after the cushion 40 raises the lampshade 30, the buckle slot 62 is also sleeved outside the buckle portion 61, which plays a role in improving the installation stability of the LED light bar, and the use of this connection method has less wear, thereby improving the life of the LED light bar.

[0053] In summary, the composite light bar housing of the LED light bar provided in this embodiment enables the LED light bar to have the advantages of high sealing, high stability, long life, easy installation, strong heat dissipation capability, etc.
