<P>PROBLEM TO BE SOLVED: To provide a lighting device which is excellent in heat-radiating performance and manufactured at low cost. <P>SOLUTION: The lighting device includes a housing, a semiconductor light-emitting light source located inside the housing, and a light-transmitting plate combined with the housing. Light emitted from the semiconductor light-emitting light source is projected to the outside of the housing by penetrating the light-transmitting plate. The semiconductor light-emitting light source has a plurality of light-emitting module which are respectively independent, each light-emitting module has a base bottom, and a plurality of light-emitting diodes arranged on an upper surface of the base bottom, and a plurality of passages for passing an air flow are formed on the base bottom. <P>COPYRIGHT: (C)2012,JPO&INPIT |
