    • A concave mirror substance 1 constituting a reflector is composed of a base material having a high thermal conductivity such as aluminum etc. An infrared-to-heat converting layer 2 is film-formed by anodizing the substrate formed of aluminum etc., so as to absorb light in a wavelength range which passes through a visible light reflecting layer 4 and convert it into heat. A gloss-forming buffer layer 3 is film-formed by calcining Si resin or polyimide resin over the inner side (the light source-side surface) of infrared-to-heat converting layer 2 at high temperatures, so as to buffer the two layers in a manner that does not allow infrared-to-heat converting layer 2 and visible light reflecting layer 4 to be in direct contact with each other, and so as to reduce the influence of projections and indentations present on infrared-to-heat converting layer 2 and smoothen the light source-side surface of visible light reflecting layer 4. In this way, it is possible to suppress performance degradation by efficient discharge of heat by converting light into heat and by alleviating thermal stress and strain due to the difference in expansion coefficient between components, and it is also possible to achieve reduction in cost, miniaturization and weight reduction.
    • 构成反射体的凹面镜物质1由铝等具有高导热性的基材构成。通过对由铝等形成的基板进行阳极氧化,形成红外线至热转换层2,以便 吸收通过可见光反射层4的波长范围内的光并将其转换成热。 通过在高温下在红外线加热转换层2的内侧(光源侧表面)上煅烧Si树脂或聚酰亚胺树脂来形成光泽形成缓冲层3,以缓冲两层 以不允许红外线热转换层2和可见光反射层4彼此直接接触的方式,并且减少存在于红外线到热转换层上的突起和凹陷的影响 从而使可见光反射层4的光源侧表面平滑化。以这种方式,可以通过将光转换成热量并通过减轻由于膨胀差引起的热应力和应变来有效地排放热量来抑制性能下降 组件之间的系数,并且还可以实现成本的降低,小型化和重量减轻。
