Abstract

The invention relates to a light source heat insulation structure. The structure comprises a reflection bowl and a curved surface heat insulation piece which are sequentially arranged; the reflectivebowl and the curved surface heat insulation piece are located on the two sides of the optical axis of the light source O; a high-reflecting film is plated on the reflective bowl, and an antireflectionfilm is plated on the curved surface heat insulation piece; the vertical incident light of the light source O generates a first optical path minimum value m after passing through the high-reflectingfilm, and generates a second optical path maximum value Mc after passing through the antireflection film; the maximum-incident-angle light of the light source O generates a first optical path maximumvalue M after passing through the high-reflecting film, and generates a second optical path minimum value mc after passing through the antireflection film; and the sum of the first optical path maximum value M and the second optical path minimum value mc is equal to the sum of the second optical path maximum value Mc and the first optical path the minimum value m. According to the scheme, the light energy loss can be reduced, the heat-emitting light can be prevented from entering the light path structure, the damage rate of optical devices is reduced, and the heat insulation effect of the light source heat insulation structure is improved.

Description

technical field [0001] The invention relates to the field of optics, in particular to a light source heat insulation structure. Background technique [0002] At present, lighting equipment has become an indispensable daily necessities in people's life. [0003] Traditional lighting equipment is usually composed of metal halide bulbs or gas discharge bulbs, but due to the working characteristics of metal halide bulbs and gas discharge bulbs, the light emitted by conventional types of metal halide bulbs and gas discharge bulbs contains a lot of infrared light And ultraviolet light, while infrared light and ultraviolet light will generate a lot of heat, if the infrared light and ultraviolet light cannot be effectively blocked from entering other optical systems, it will cause damage to the lighting equipment. To solve such problems, it is usually to use reflective bowl coating or install heat shields to block infrared light and ultraviolet light from entering the light path. H...
