Light source lamp and light source device

摘要: PROBLEM TO BE SOLVED: To provide a light source lamp in which use efficiency of beam is enhanced by reducing the diffusion owing to reflection. SOLUTION: The 1 has light-emitting tube 2 and reflection mirror 3, reflective surface 3 equipped with curved 4 shape concave surface, an irregular 5 connected opening edge 4. constitution that very small reflecting plate 8 cubic type are arrayed lengthwise breathwise, reflects incident direction parallel concerned. Divergent from surely reflected toward 2, when made on 5. emitted as light, without being diffused outside. Thus, emission luminous intensity can be enhanced. COPYRIGHT: (C)2001,JPO
