<P>PROBLEM TO BE SOLVED: To provide a lighting device in which heat radiation is made uniform by improving heat radiation of multi-point light source units even in the case a plurality of multi-point light source units are combined, and imbalance of deterioration of lifetime of components such as emitters due to deviation of heat radiation is prevented. <P>SOLUTION: On the lighting device, multi-point light source units 2 having a plurality of emitters 20 arranged on a substrate 10 are freely combined with each other. Then, an enclosure 30 having a thermal conductivity equal to or larger than the substrate is provided at the outer circumference of the substrate 10, and the enclosure 30 is connected detachably to the enclosure 30 of the mutually adjoining multi-point light source unit 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
