Reflector, illumination device with reflector, and method for manufacturing reflector

Abstract

The invention relates to a reflector for illumination equipment. The reflector comprises a substrate (1) and at least one reflecting hole (2) formed in the substrate (1), wherein the substrate (1) comprises a plurality of sub substrates (A and B); at least one sub reflecting hole (2A or 2B) is formed in each sub substrate (A or B); and the sub substrates (A and B) can be stacked together, so that the sub reflecting holes (2A and 2B) of the sub substrates (A and B) are aligned to form the reflecting hole (2). According to the reflector, a plating with uniform thickness can be obtained during vacuum plating, so that high reflectivity and optical efficiency are achieved. The invention also provides the illumination equipment with the reflector, and a method for manufacturing the reflector.

Description

technical field [0001] The invention relates to a reflector, an illuminating device with the reflector and a manufacturing method of the reflector. Background technique [0002] Reflectors are very common components in lighting equipment. In order to obtain high optical efficiency, coatings are required on the reflector. Two processes of vacuum coating and anodic oxidation are generally used in the prior art. However, in smaller and more slender reflectors, especially at the bottom of the reflector, it is difficult to obtain a coating with a uniform thickness through a vacuum coating process. In order to obtain a coating with a uniform thickness, it is generally attempted to enlarge the size of the reflector in the prior art, but sometimes the size of the product is limited, and there is not enough space to use such a large-sized reflector. Of course, the anodizing process is also a conventional solution, and a coating with uniform thickness can be obtained on reflectors ...

AI Technical Summary

Problems solved by technology

However, in smaller and more slender reflectors, especially at the bottom of the reflector, it is difficult to obtain a coating with uniform thickness by vacuum coating process

In order to obtain a uniform thickness of the coating, in the prior art usually try to enlarge the size of the reflector, but sometimes the size of the product is limited, there is not enough space to use such a large size reflector

Of course, the anodizing process is also a conventional solution, and a coating with uniform thickness can be obtained on reflectors of any shape and size. However, the optical efficiency of the coating obtained by this process is much lower than that of the vacuum coating process.
