| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a lighting system in which increase of the number of components is suppressed and cooling efficiency of a light source element is improved. <P>SOLUTION: The light source element 140 is mounted on the same substrate 130 as the power source circuit 150. A power source cover 120 is arranged so as to cover and hide the power source circuit 150. An opening part for taking in the outside air in order to cool the power source circuit 150 is installed in the power source cover 120 and a case 110 side-face. A cover exhaust port 125 for discharging the air for cooling the light source element 140 is installed in the power source cover 120. The power source circuit 150 in the power source cover 120 is cooled by the air taken in by the opening part and a part of the air taken in cools the power source element 140 through the cover exhaust port 125. <P>COPYRIGHT: (C)2013,JPO&INPIT |
