LED (Light Emitting Diode) lamp of T-type light source

Abstract

The invention discloses an LED (Light Emitting Diode) lamp of a T-type light source. The LED lamp comprises a lamp body, a heat dissipation part, a lamp panel, a lampshade and a pressing plate, wherein a plurality of first convection holes are formed in the lamp body; a first locating clamping groove is formed in the inner side of the lamp body; at least two first snap joints are arranged at a wide mouth end of the lamp body; a plurality of second convection holes are formed in the heat dissipation part; the heat dissipation part is clamped in the lamp body through the locating clamping groove; the locating clamping groove causes the plurality of second convection holes and the plurality of first convection holes to be in one to one correspondence; the first convection holes and the secondconvection holes are used for heat loss through convection; the lamp panel is fixed to the heat dissipation part through the at least two first snap joints; at least four second snap joints are arranged at an opening end of the lampshade; the lampshade is clamped at the wide mouth end of the lamp body through the at least four second snap joints; and the pressing plate is clamped on the upper surface of the heat dissipation part for the secondary fixation of the lamp panel on the heat dissipation part. The LED lamp has the beneficial effects that the heat dissipation effect of the LED lamp isimproved; the LED lamp is simple in structure, is assembled with no need of bolts, can improve the production efficiency and saves the production cost.

Description

technical field [0001] The invention relates to the technical field of LED manufacturing, in particular to an LED lamp with a T-shaped light source. Background technique [0002] At present, the LED lamps with T-shaped light sources on the market are mostly plastic-clad aluminum structures (heat sinks are directly injected into the plastic parts), the mold is complex and the production efficiency is low, and the cost of die-casting aluminum structures is high. The surface requires secondary treatment. The assembly method is fastened with screws, that is, the light boards are directly fixed to the heat sink with screws, and the low production efficiency is not suitable for mass automatic production and assembly. [0003] Therefore, there is an urgent need for an LED lamp with a simpler structure of the heat dissipation component and screw-free assembly, so as to further improve the production efficiency of the LED lamp. Contents of the invention [0004] In view of the abo...

Problems solved by technology

[0002] At present, the LED lamps with T-shaped light source on the market are mostly plastic-clad aluminum structure (heat dissipation parts are directly injected into the plastic parts), the mold is complicated, the production efficiency is low, and the cost of die-casting aluminum structure is high. The surface needs to be treated twice.

The assembly method is fastened by screws, that is, the light boards are directly fixed to the heat sink with screws, and the production efficiency is low, which is not suitable for mass automatic production and assembly.
