Title: Light source device for exposure
Inventor: SUETSUGU HIROSHI
IPC: G03B27/54
Filed: 1984-05-02
Abstract: PURPOSE:To obtain the light source device for exposure which shortens the necessary time of the exposure process during the formation of a fluorescent screen and also improves production efficiency by providing a concave reflecting mirror at the opposite side of a mercury lamp viewed from the opening part of a light source part, and increasing the intensity of radiant light from the light source part. CONSTITUTION:Upward light 6a of light emitted by the mercury lamp 3 of the light source for exposure contributes to exposure as well as before and further light emitted toward the concave surface reflecting mirror 8 which is not utilized conventionally is reflected by the concave reflecting mirror 8 and emitted from the opening part 1. Consequently, the intensity of the light emitted from the opening part is increased greatly as compared with a conventioal device. Then, the necessary quantity of exposure depends upon the kind of a fluorescent body, but the exposure time is shortened as the light intensity per unit time increases, so the exposure time is shortened greatly by using the exposure device. Further, a glass plate is provided between the mercury lamp and concave reflecting mirror to eliminate stains sticking on the concave reflecting mirror, preventing a a decrease in reflection factor.
