Abstract

PURPOSE:To enhance uniformity ratio of illuminance, by putting the focus of a reflecting plate being in the rear from side of a lamp in the diameter of the lamp tube and setting the inclination of optical axis theta to the range expressed by the equation tan<-1>a/h<=theta<=tan<-1>a/2h (a is interval of lamp and h is distance between center of lamp and face to be irradiated). CONSTITUTION:A position of opening face 11 of reflecting plate 10 is put to height between center of tube diameter of lamp 12 and lower end part of tube diameter of lamp 12. The focus of the rear face from side of reflecting plate 10 is put in the tube diameter of lamp 12. Inclination angle theta of optical axis P is set to range expressed by the equation tan<-1>a/h<=theta<=tan<-1>a/2h, when interval of lamp 12 is (a) and distance from center of lamp 12 to face G to be irradiated is (h).
