<P>PROBLEM TO BE SOLVED: To provide an LED lighting fixture which can make compatible the securing of the illuminance of lighting and the reduction of the heat generation of the LED. <P>SOLUTION: The main part of a boat-like LED lighting fixture 1 is composed of a lens member 2 in which irradiation light from an LED 3 as a light source is diffused by being transmitted through the lens member 2 and the diffused light is projected as lighting. The LED lighting fixture 1 is provided with countermeasures for heat generation and insufficient illuminance. As the countermeasure for heat generation, for example, heat dissipation holes 22, 23 are formed at side walls 5a, 5b of the lens member 2, the substrate 11 of the LED 3 is formed of an aluminum material, copper rods 28, 29 are mounted to the substrate 11, or resistances 14, 15 are formed in an aerial wiring structure. As the countermeasure for insufficient illuminance, the curvature of a lens 16 of the lens member 2 is set to be larger. <P>COPYRIGHT: (C)2012,JPO&INPIT |
