PROBLEM TO BE SOLVED: To provide a luminaire capable of cooling a lamp and of an easy mounting structure of a lens. SOLUTION: A light source 22 is protruded outside from a light-source opening 251 of a lens 25, so that the heated light source 22 can be easily cooled. At the same time, air goes out and comes in from a gap 28 between an inner periphery face of the light-source opening 251 and the light source 22, thereby heat is prevented from stuffing inside the luminaire 10 and temperature inside the luminaire 10 can be lowered. Further, a tip of the light source 22 can be grabbed from outside, so that replacement of the light source 22 can be easily carried out without detaching the lens 25. Accordingly, the removal of the lens 25 becomes unnecessary, making a mounting structure of the lens 25 simple. Moreover, the tip of the light source 22 is protruded outside, thereby the luminaire 10 can be made compact. COPYRIGHT: (C)2010,JPO&INPIT |
