LED (light emitting diode) light fitting

Abstract

The invention relates to an LED (light emitting diode) light fitting which comprises a shell and a light source device; the shell is provided with a mounting position and a light emitting surface; the light source device comprises a reflection mirror, an LED light source and a heat radiation unit; the LED light source is fixed on the heat radiation unit; the heat radiation unit is fixed on the mounting position; the light reflection mirror is fixed on the light emitting surface, and is used for reflecting and refracting the light rays emitted by the LED light source; the light reflection mirror comprises a set of main light reflection mirrors, a set of auxiliary light reflection mirrors and at least one pair of lateral light reflection mirrors, wherein the set of main light reflection mirrors and the set of auxiliary light reflection mirrors are respectively connected with the pair of lateral light reflection mirrors; the set of main light reflection mirrors comprise at least one main light reflection mirror; the set of auxiliary reflection mirrors comprise at least one auxiliary light reflection mirror; the area of the set of main light reflection mirrors is different from that of the set of auxiliary light reflection mirrors; and the pair of lateral light reflection mirrors comprise two lateral light reflection mirrors which are arranged symmetrically, and the symmetrical surfaces are crossed with the LED light source. The structure of the light reflection mirror is especially suitable for the illumination of thin and long space, also is much easier to radiate heat, and is much better for the space utilization in the shell of the light fitting.

Description

【Technical field】 [0001] The invention relates to an LED lighting fixture, in particular to an LED lighting fixture structure used in special environments such as tunnels and roadways. 【Background technique】 [0002] Most of the reflector cups of current LED lamps have a circular symmetrical structure, and the LED package light source is installed at the bottom, so that the emitted light is uniform and radioactive. The projection of the LED light of the shaped reflector is circular. In such narrow and long environments, such as tunnels and roadways, the number of LED light sources must be increased to meet the lighting requirements. [0003] In addition, in terms of heat dissipation of LED lamps, most of them use thermal ribs on the lamp housing to dissipate heat from the lamps. Therefore, in such a long and narrow environment, the problem of heat dissipation of LED lamps has always been a problem to be solved. [0004] Therefore, there are defects in the prior art and need...

[0002] Most of the reflector cups of current LED lamps have a circular symmetrical structure, and the LED package light source is installed at the bottom, so that the emitted light is uniform and radioactive. The projection of the LED light of the shaped reflector is circular. In such narrow and long environments, such as tunnels and roadways, the number of LED light sources must be increased to meet the lighting requirements.

[0003] In addition, in terms of heat dissipation of LED lamps, most of them adopt thermal ribs on the lamp housing to dissipate heat from the lamps. Therefore, in such a long and narrow environment, the problem of heat dissipation of LED lamps has always been a problem to be solved.
