Waterproof LED lamp tube

Abstract

The invention relates to a waterproof LED lamp tube. A heat dissipating base comprises a mounting platform, protruding bars are arranged on the two sides of the mounting platform, and a groove used for mounting an LED substrate is formed among the two protruding bars and the platform. The top of each protruding bar extends inward to be provided with a first limiting plate, the top of each protruding bar extends outward to be provided with a second limiting plate, the top surfaces of the first limiting plates are provided with inclined surfaces inclining inward, and the top surfaces of the second limiting plates are provided with inclined surfaces inclining outward. LED chips are arranged linearly on the LED substrate. Guide grooves comprise inward first slide grooves and downward second slide grooves, the openings of the first slide grooves face outward, and the openings of the second slide grooves face upward. Guide bars comprise inward first slide bars and downward second slide bars, the first slide bars are matched with the first slide grooves, and the second slide bars are matched with the second slide grooves. The surfaces of the second limiting plates are smooth and can have the reflection effect, thus, light on the side face of a lampshade can be reflected to the bottom of the side face of the lampshade, and the lampshade can made to emit light more evenly.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED waterproof lamp tube. Background technique [0002] The LED substrate of the existing LED light tube is set on the installation plane of the heat dissipation base. Since the LED chip emits light at an angle of 120°, and the light-emitting surface of the mask is set at 180°, the light cannot be irradiated to the bottom positions on both sides of the light tube. As a result, the phenomenon of uneven light emission of the lamp tube is caused. For waterproof lamp tubes, the waterproof of the lamp tube is mainly set at the connection between the mask and the base of the lamp tube, and the connection between the end caps of the lamp tube at both ends; for general lamp tubes, since waterproofing is not required, the fixing method It can be arbitrary. The commonly used fixing is to fix the base with screws. Although this fixing method is firm, it is troublesome to install, and it is n...

For waterproof lamp tubes, the waterproof of the lamp tube is mainly set at the connection between the mask and the base of the lamp tube, and the connection between the end caps of the lamp tube at both ends; for general lamp tubes, since waterproofing is not required, the fixing method It can be arbitrary. The commonly used fixing is to fix the base with screws. Although this fixing method is firm, it is troublesome to install, and it is not suitable for waterproof light tubes. It is easy to fix by destroying the overall structure of the base. Leak occurs
