LED bar lamp

Abstract

The invention provides an LED bar lamp which comprises a lamp housing (1) with a closed cavity and a lamp holder (2), wherein the lower end of the lamp holder (2) is fixedly connected with the upper end of the lamp housing (1); a base (3) is arranged in the lamp housing (1); one end of the base (3) hermetically penetrates through the lamp housing (1) to be fixedly connected with the lamp holder (2); an LED light (4) is arranged at the other end of the base (3); the LED light (4) is electrically connected with the lamp holder (2); the closed cavity of the lamp housing (1) is filled with protective gas; first plating (5) is arranged at the lower part of the inner surface of the lamp housing (1); second plating (6) is arranged at the lower part of the outer surface of the lamp housing (1); and the tops of the first plating (5) and the second plating (6) are located on the same horizontal plane. The LED bar lamp has favorable heat dissipation performance and is beneficial to protecting human visual systems.

Description

technical field [0001] The invention relates to the technical field of lighting equipment, in particular to an LED bar light. Background technique [0002] The existing LED bar light utilizes a holographic plastic film layer with a periodic microstructure prepared on a plastic film, such as an orthogonal grating, a two-dimensional hexagonal lattice structure, and the like. When the LED light shines on the holographic plastic film layer, the microstructure on the holographic plastic film layer will diffract the light, and the proper selection of the structure period can make the diffracted light have many diffraction orders, so that a light source can produce many bright spots spread out on all sides. Diffraction light of different wavelengths forms different diffraction angles, making the light produce colorful and gorgeous effects. Because LED lamps generate a lot of heat when they emit light, and the existing bar lamps do not install a heat sink in the lamp body in order ...

AI Technical Summary

Problems solved by technology

Because LED lamps generate a lot of heat when they emit light, and the existing bar lamps do not install a heat sink in the lamp body in order to obtain better light diffraction effects, the heat generated by the LED lamps seriously affects the service life of the LED lamps. , In addition, the light generated by the diffraction of LED lights can directly contact the visual system of the human eye, causing damage to the visual system of the human eye
