<P>PROBLEM TO BE SOLVED: To provide a lighting device capable of improving heat radiation effects with a blower by making a wind generated by the blower efficiently flow to a heat sink even if the lighting device hardly concentrate the wind generated by the blower to the heat sink due to its shape. <P>SOLUTION: The lighting device includes a light-emitting element 151, the heat sink 120 thermally connected with the light-emitting element 151 and radiating heat generated by the light-emitting element 151, the blower 130 having blades generating the wind for radiating the heat of the heat sink 120, a case 110 having a metal cap 101 at one end and storing the blower 130, and a frame 137 for regulating a wind path of the wind in the circumference of the blades in a centrifugal direction. A gap which becomes the wind path of the wind in a rotary axis direction of the blades is arranged between the heat sink 120 and the frame 137. <P>COPYRIGHT: (C)2013,JPO&INPIT |
