ABSTRACT:
The reflection mirror of this invention is considered an improvement over the conventional art in that it has a plating means that smoothes the inner surface of the reflection mirror body and a means for intercepting the heat of the light and that the mirror can be assembled into a desired size. The feature of this improvement is that the simplified polishing work that smoothes the inner surface of the reflection mirror body does not degrade but rather improves the quality of the mirror, uniformity of illumination directivity, and productivity. Since the heat absorbing layer absorbs heat rays, any deterioration of an object being illuminated can be prevented. Another advantage is that it is possible to prevent loss of freshness of food, and discoloration and deformation of products that might otherwise be caused by heat rays.
