Abstract

PURPOSE: To improve the irradiation efficiency and reduce power consumption, by fitting a light source, where an aperture variable reflective curved plate is caused to adhere closely to the outside circumference of the fluorescent lamp where a metal oxide reflective film is applied within the range of 260W320° and a fluorescent film is applied on this reflective film within the range of 270W320°, to the copying machine.
CONSTITUTION: Reflective film 12 consisting of TiO and so on is applied to the inside face of fluorescent lamp 15 within the angle range of 260W320°, and a fluorescent film is provided on this film within the range of 270W320°. Aperture variable mirror face of curved plate 1 where the reflection material for visible rays is applied is caused to adhere closely to the outside circumference of fluorescent lamp 15. This electric discharge lamp is fitted to the copying machine and is lit through nostage or multistage dimmers as required. The aperture angle of the reflective plate is adjusted manually or while interlocking with dimmers. As a result, the irradiation efficiency can be enhanced, and power consumption can be reduced.
