Gold halogen PAR lamp

Abstract

The invention discloses a gold halogen PAR lamp which comprises a lamp cap, a light reflecting lamp cup and a gold halogen lamp, wherein the gold halogen lamp is arranged in a cup body of the light reflecting lamp cup, and the light reflecting lamp cup is an aluminum cup body. The upper part and the lower part of the light reflecting lamp cup are respectively provided with a vent hole. The gold halogen PAR lamp has the advantages of high use safety, stable color temperature, low speed of light attenuation, long service life and the like, and the phenomenon of light reflecting film glass can not occur within the service life.

Description

Technical field: [0001] The invention relates to a metal halide PAR lamp. Background technique: [0002] Because the metal halide lamp replaces the traditional halogen lamp as the internal illuminant of the PAR lamp, it has high light efficiency and good color rendering, so it is more and more recommended by all parties. Although the advantages are prominent and significant, this metal halide PAR lamp still has disadvantages, mainly because the reflector cups of the PAR lamp are all made of glass, resulting in a relatively heavy weight of the entire PAR lamp. When the PAR lamp of the glass reflector is suspended, there is a safety hazard of falling and hurting people; in addition, the reflector cup of the PAR lamp needs to be coated with aluminum film as a reflective film on the inner surface during the manufacturing process, but the glass and aluminum are affected. The thermal expansion rate is different from the cold shrinkage rate, which leads to the fact that after a pe...

Although the advantages are prominent and significant, this kind of metal halide PAR lamp still has disadvantages, mainly because the reflector cups of the PAR lamp are all made of glass, resulting in a large weight of the whole PAR lamp.

When the PAR lamp of the glass reflector is suspended, there is a safety hazard of falling and hurting people; in addition, the reflector cup of the PAR lamp needs to be coated with aluminum film as a reflective film on the inner surface during the manufacturing process, but the glass and aluminum are affected. The thermal expansion rate is different from the cold shrinkage rate, which leads to the fact that after a period of use, due to the alternation of cold and heat, some aluminum films are prone to peeling off, which reduces the reflective rate of the reflector cup and affects the aesthetic effect of the product; and because of the PAR lamp Generally, it is a fully enclosed structure, and glass is a poor conductor of heat, so that the heat generated by the PAR lamp during the ignition process cannot be dissipated in time and quickly, and the heat accumulation effect occurs in the lamp body, which reduces the electrical performance and optical performance of the metal halide lamp. and service life
