<P>PROBLEM TO BE SOLVED: To achieve small footprint by saving space required when mounted. <P>SOLUTION: A luminaire 5 includes a light source unit 22 having a LED 11 for emitting illumination light and a collector lens 12 for condensing the illumination light, and a projection tube body 21 for holding a light source unit 22 and guiding the illumination light. The light source unit 22 has a heatsink 23 for holding the LED 11 to emit heat from the LED 11, and a lens frame 24 for holding the collector lens 12 and also for holding the heatsink 23 so that a relative position of the LED 11 with respect to the collector lens 12 may be changed. The projection tube body 21 has a communication hole 21d for making the projection tube body 21 communicate with the outside, and inserts and fits the lens frame 24 to the communication hole 21d, thereby holding the light source unit 22. <P>COPYRIGHT: (C)2009,JPO&INPIT |
