Problems solved by technology

However, the traditional lampshade can only simply reflect the light to the front, without directivity, and cannot effectively concentrate the light in the area that needs to be illuminated, so the use efficiency of the lamp is low, and there is a lot of unnecessary scattered light. , will have an impact on drivers, pedestrians and even surrounding homes on the road

Abstract

The invention provides an illuminating device and a light reflecting cover thereof which are used for reflecting light rays emitted by a light source. The light reflecting cover comprises at least one reflecting sheet and a cone structure forming by the reflecting sheet; and the cone structure is provided with a plurality of conical parts, a first end surface and a second end surface, wherein the first end surface corresponds to the second end surface, the first end surface is used for arranging the light source, the second end surface is a light emitting end, and each conical part comprises a plurality of reflecting surfaces.

Description

technical field [0001] The present invention relates to an illuminating device and a light reflection cover thereof, in particular to a light reflection cover with high directivity, which can concentrate light in a required area and within a small angle. Background technique [0002] Traditional street lighting devices mostly use mercury lamps, high-pressure sodium lamps or metal halide lamps, etc., and are equipped with hemispherical lampshades to reflect the rear or side light to the front through the hemispherical reflective surface. However, the traditional lampshade can only simply reflect the light to the front, without directivity, and cannot effectively concentrate the light in the area that needs to be illuminated, so the use efficiency of the lamp is low, and there is a lot of unnecessary scattered light. , will have an impact on drivers, pedestrians and even surrounding homes on the road. Contents of the invention [0003] The object of the present invention is...
