| Summary: | A reflection mirror includes a reflection mirror body and a photo sensor for luminance measurement. The reflection mirror body has a three-dimensional curved reflection surface that receives light from a light source and reflects the light toward an object to be illuminated. The reflection mirror body also has a through hole in the vicinity of the center of the reflection surface. The center axis of the through hole is substantially parallel to a light path between the refection mirror body and the object but perpendicularly intersects a light path between the light source and the reflection mirror body. The photo sensor is received within the through hole and adapted to measure the luminance of an illuminated surface of the object. |
