<P>PROBLEM TO BE SOLVED: To reduce the number of components; to simplify an assembly work; to prevent damage of an LED; and to ensure positioning between the LED and a bracket member. <P>SOLUTION: This light source unit includes an LED substrate 5 on which a plurality of LEDs 52 are provided in a row, a heat conduction member 6 having viscoelasticity, a heat radiation member 7 wherein a slide groove 71 extending in the longitudinal direction is formed, and the bracket member 8 having a locking pawl 821 to be locked slidably into the slide groove 71. The light source unit is constituted so that the heat radiation member 7, the heat conduction member 6, the LED substrate 5 and the bracket member 8 are mutually pressed and contacted by sliding and moving the bracket member 8 and the heat radiation member 7 so that the locking pawl 821 is locked into the slide groove 71 in the state where the heat radiation member 7, the heat conduction member 6 and the LED substrate 5 are piled in this order. <P>COPYRIGHT: (C)2011,JPO&INPIT |
