Back coating type glass reflector

Abstract

The invention discloses a back coating type glass reflector arranged in a street lamp. The reflector consists of a shell and a reflecting film, wherein the section of the shell is in an arc shape; the reflecting film is covered on the arc external surface of the shell, and consists of a reflecting layer and an external protective layer; the reflecting layer is coated on the external surface of the shell, the external protective layer is tightly jointed with the reflecting layer and is coated on the upper face of the reflecting layer; the shell is prepared from a novel material, namely, borosilicate glass with the advantages of high light transmittance, high temperature resistance, lower thermal expansion coefficient and the like, thus the maintenance factor of the lamp is improved; and in addition, the reflecting film is prepared from a novel material by a novel film coating process, the reflecting layer is made of a metallic silver material, and the external protective layer is prepared from a vulcanization-proofing material, thus the initial efficiency of the lamp is greatly enhanced. The reflector has the advantages that the maintenance factor of the lamp is effectively improved, the initial efficiency of the lamp can be preferably maintained for a long time, and the purposes of enhancing the lighting effect, saving electric energy, reducing investment and realizing green lighting are achieved.

Description

Technical field: [0001] The invention relates to a material selection, a process method and a product of a reflective device capable of improving the maintenance factor of a lamp and increasing the initial efficiency of the lamp, especially a reflector installed and used in a road lighting lamp. Background technique: [0002] In recent years, with the shortage and shortage of global energy sources, countries around the world are vigorously advocating energy conservation while researching new energy sources, and have invested a lot of manpower and material resources to develop new energy-saving technologies, hoping that the use of energy can be effectively saving. At the same time, my country has also proposed a major measure of energy conservation and emission reduction in the "Eleventh Five-Year Plan". Road lighting fixtures that consume a lot of electric energy - street lamps, naturally need to apply new energy-saving technologies to meet the current energy-saving concept...

AI Technical Summary

Problems solved by technology

If the reflector repeatedly expands and shrinks for a long time, it will cause the aging of the reflective layer and further reduce the reflection coefficient. After one year, the efficiency of the lamp is only about 0.65, and the maintenance factor of the lamp is reduced to about 0.5.
