<P>PROBLEM TO BE SOLVED: To improve heat dissipation efficiency of a light source without disturbing air flow. <P>SOLUTION: The light source module 120 has LEDs 122a (light source), a substrate 122, and heat radiating fins 121c2 (heat radiation part). The substrate 122 has a flat plate shape. The LEDs 122a (light source) are mounted on the substrate 122. The heat radiating fins 121c2 (heat radiation part) have a plate shape. The heat radiating fins 121c2 radiate heat from both front and rear surfaces by the air flow flowing in a nearly vertical direction to the substrate 122. The heat radiating fins 121c2 are formed by cutting and bending over a part of a heat sink 121. <P>COPYRIGHT: (C)2012,JPO&INPIT |
