Abstract

The invention discloses an LED light source facilitating light distribution through light ray concentration, and relates to the technical field of LED light source structures for light distribution. The LED light source comprises a protective shell, wherein a reflective lampshade is fixedly mounted at the top of the protective shell, a light source bottom plate is fixedly mounted on the inner side wall of the protective shell and located at the top of the protective shell, a plurality of LED light sources are fixedly mounted on the light source bottom plate, the top of the light source bottom plate is rotationally provided with a plurality of arc-shaped reflection plates through a plurality of rotating mechanisms to form a circular tube structure, and the circular tube structure is matched with the light source bottom plate. According to the invention, the cylindrical ring moves in the axis direction of the circular tube structure formed by the multiple arc-shaped reflection plates through the stretching mechanism, the multiple arc-shaped reflection plates are rotated and separated through the rotating mechanism under the action of the elastic mechanism to form a conical structure, light rays of the LED light source are reflected, then different focal lengths are formed, and the light source bottom plate can be cooled in time through the cooling mechanism, so that light distribution is facilitated.

Description

technical field [0001] The present invention relates to the technical field of LED light source structure for light distribution, and in particular, to an LED light source whose light concentration is helpful for light distribution. Background technique [0002] The LED light source is a light-emitting diode light source. This light source has the advantages of small size, long life and high efficiency. It can be used continuously for up to 100,000 hours. In the future, the application of LED light source in the field of lighting will also become mainstream.

Problems solved by technology

[0003] In the prior art, when the LED lamp is irradiating, the heat generated by the LED light source has a great influence on the light distribution. Generally, the heat is dissipated through natural heat dissipation. In addition, the focal length of most LED lamps cannot be adjusted. When different distances need to be irradiated , prone to astigmatism, resulting in weak brightness at the edge of the light spot on the illuminated surface, in view of this, we propose a LED light source that concentrates light and helps light distribution
