Embodiment Construction

[0040] Preferred embodiments according to the present invention will be described below with reference to the relevant drawings, wherein the same elements will be described with the same reference numerals.

[0041] see Figure 1A to Figure 1C , which shows a light reflector of a preferred embodiment of the present invention, Figure 1B for Figure 1A top view of Figure 1C for Figure 1A In the side view, it includes a plurality of reflective sheets 10 assembled to form a pyramidal structure 1 , or a single reflective sheet 10 is bent to form a pyramidal structure 1 . The cone structure 1 has a first cone portion 11, a second cone portion 12, and a first end face 13 and a second end face 14 corresponding to each other, wherein the first end face 13 is an open end for setting a light source, also It can be a closed end, and the second end surface 14 is a light-emitting end. The first tapered portion 11 and the second tapered portion 12 are stacked up and down to form the pyr...

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...
