Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Example: As attached Figures 1 to 8The environmental protection cabinet gas box lighting lamp shown is used to be installed on the cabinet body of the environmental protection cabinet, and includes a lamp holder 1, a bulb 2, a lampshade 3 and an end cap 4. The lampshade 3 is installed on one side of the lamp holder 1, and a through hole 5 for the bulb 2 to pass through is provided in the middle of the lamp holder 1. The bulb 2 is arranged in the lampshade 3, and the bulb 2 is a strip-shaped LED bulb 2. The end cap 4 is detachably installed on the other side of the lamp holder 1, and the bulb 2 is confined in the lampshade 3. The end cap 4 is provided with a wire hole 6 for the wire of the bulb 2 to pass through. A through hole is opened on the cabinet body of the environmental protection cabinet. When installing, the lamp holder 1, the bulb 2, the lampshade 3 and the end cap 4 are first assembled together, and the lampshade 3 is passed through the through hole on the cabinet body so that it extends into the cabinet body, and then the lamp holder 1 is installed on the cabinet body of the environmental protection cabinet to complete the overall installation. When the bulb 2 needs to be replaced, it is only necessary to remove the end cap 4, pull out the old bulb 2, insert the new bulb 2, and then install the end cap 4. The structure is simple and reliable, and the volume is small and compact, which can not only significantly reduce the production cost, but also facilitate the early assembly and the later disassembly and maintenance operations.

[0036] As attached Figure 3 As shown, the outer end of the lampshade 3 is provided with a limiting flange 7 extending toward the periphery, and the two are an integrated structure. The side of the lamp holder 1 close to the lampshade 3 is provided with an installation groove 8 for the limiting flange 7 to be embedded, and the depth of the installation groove 8 is equivalent to the thickness of the limiting flange 7. When the lamp holder 1 is installed on the cabinet body of the environmental protection cabinet, the lamp holder 1 presses the limiting flange 7 of the lampshade 3 against the cabinet body surface of the environmental protection cabinet. The positioning installation of the lampshade 3 can be realized by only connecting the lamp holder 1 to the cabinet body with screws, and the installation operation is very convenient.

[0037] As attached Figure 3 As shown, a plurality of positioning posts 9 are arranged along the circumferential direction on the outer end surface of the limiting flange 7, and a plurality of positioning holes 10 are arranged on the lamp holder 1 to be plugged and matched with the positioning posts 9. In this embodiment, there are three positioning posts 9 and three positioning holes 10. The lampshade 3 can be positioned to improve the stability of the installation of the lampshade 3 and avoid shaking during use.

[0038] As attached Figure 4 As shown, the lamp holder 1 is provided with a plurality of mounting flanges 11 at positions corresponding to the inner side of the opening 5, the positioning holes 10 are provided on the mounting flanges 11, and an inner recess 12 for exposing a portion of the limiting flange 7 is provided between each two adjacent mounting flanges 11. The positioning holes 10 are provided on the mounting flanges 11, which frees up more space for the positioning holes 10, and can improve the strength of the connection part. The inner recess 12 exposes a portion of the limiting flange 7, which is convenient for directly ejecting the lampshade 3 when it is removed.

[0039] As attached Figure 3As shown, an annular sealing groove 13 is provided on the outer circumferential surface of the inner end of the limiting flange 7, and a sealing ring 14 is embedded in the annular sealing groove 13 for forming a sealing match with the cabinet surface, and the outer circumferential surface of the sealing ring 14 fits the inner circumferential surface of the annular sealing groove 13. This design can ensure the sealing between the lamp holder 1, the lampshade 3 and the cabinet, and prevent the gas inside the cabinet from leaking to the outside.

[0040] As attached Figure 2 As shown, the outer periphery of the end cap 4 is provided with a plurality of connecting flanges 15 along the circumferential direction. The connecting flanges 15 and the end cap 4 are an integrated structure. Each connecting flange 15 is connected to the lamp holder 1 by screws. In this embodiment, the number of connecting flanges 15 is three. The outer periphery of the end cap 4 is provided with connecting flanges 15 connected to the lamp holder 1, which provides more operating space for the installation of screws and facilitates the disassembly and assembly operations.

[0041] As attached Figure 2 and attached Figure 6 As shown, the end cap 4 is also provided with a plurality of groups of positioning structures 16, the number of which is equal to the number of the connecting flanges 15. In this embodiment, the number of the positioning structures 16 is three groups, and the positioning structures 16 include two positioning ribs 17 respectively arranged on both sides of the corresponding connecting flanges 15. A positioning groove 18 is formed between the two positioning ribs 17 of the same group of positioning structures 16 for the corresponding connecting flanges 15 to be embedded. This design can position the connecting flange 15, which can not only improve the stability of the cover plate installation structure, but also can position the connecting flange 15 and the docking hole on the lamp holder 1, so as to facilitate the fast and accurate screwing in of the screws.

[0042] As attached Figure 6 As shown, each two adjacent groups of positioning structures 16 are connected by an arc-shaped inwardly concave supporting rib 19, the end cover 4 abuts against the supporting rib 19, and an arc-shaped inner groove 20 is provided at the position where the end cover 4 abuts against the supporting rib 19. The supporting rib 19 props up the end cover 4, which not only provides a larger space for the positioning column 9 on the lampshade 3 to avoid assembly interference, but also the gap formed between the end cover 4 and the lamp holder 1 is conducive to heat dissipation.

[0043] As attached Figure 6 As shown, the lamp holder 1 is provided with a plurality of mounting holes 21 for screws to pass through, the number of which is equal to the number of the supporting ribs 19, and the mounting holes 21 are arranged concentrically with the corresponding supporting ribs 19. The mounting holes 21 are arranged on the lamp holder 1 for screws to pass through, so that the end cover 4 and the cabinet can be connected together by screws, and because the mounting holes 21 are arranged concentrically with the corresponding supporting ribs 19, it can ensure that the screws can be installed smoothly under the premise that the area of ​​the lamp holder 1 is smaller.

[0044] As attached Figure 7As shown, the outer end surface of the end cap 4 is also provided with a plurality of weight-reducing grooves 22 in a circumferential array, and the weight-reducing grooves 22 are polygonal in shape. This design can not only reduce the overall weight, but also use less raw materials and lower the production cost. In addition, the weight-reducing grooves 22 are arranged on the inner side of the lamp holder 1, which fits with the cabinet surface to form a shield, thereby making the outer surface of the lamp holder 1 more beautiful.
