<P>PROBLEM TO BE SOLVED: To provide a lighting device having both a waterproofing function and a heat radiation function. <P>SOLUTION: The lighting device 100 includes a case 110, a heat sink block 120, an LED array 130, two waterproofing plastic sheets 140a, 140b, and two covers 150a, 150b. The case 110 has a fluid inlet 112, a fluid outlet 114, and two partition grooves 116. The heat sink block 120 has a platform 122 for mounting, and a flow passage 124. The LED array 130 is arranged on the platform 122 for mounting, and the covers 150a, 150b respectively cover the waterproofing plastic sheets 140a, 140b and a part of the case 110, and have second openings 152 corresponding to first opening 142. Consequently, heat is radiated from the LED array 130 since a fluid penetrates the flow passage 124 through the second opening 152 and the first opening 142. <P>COPYRIGHT: (C)2011,JPO&INPIT |
