<P>PROBLEM TO BE SOLVED: To solve such a problem that a conventional lighting device has a configuration in which a power supply for lighting an LED is provided inside a polytope 102, therefore, heat generated from the power supply accumulates inside the polytope 102 and the power supply is put under a high temperature for a long period of time, consequently, it causes various adverse effects. <P>SOLUTION: A lighting device includes a first heat dissipation part for dissipating heat generated from the power supply 4 via a light source 3. Consequently, the lighting device efficiently dissipates heat without allowing the heat to accumulate in the light source 3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
