ABSTRACT:
An LED lamp can be used as a light source of a lighting device. The LED lamp can be combined with a reflecting mirror formed as a paraboloid of revolution, to obtain desired light distribution characteristics, as with a conventional light source. The emission surface of the LED lamp for the light source of the lighting device can be rectangular, and the ratio between a short side and a long side thereof is set in a range of 1:2 to 1:6. Therefore, it is possible to form a light distribution pattern similar to that of a filament, which is conventionally used as an emission source. It is also possible to use almost all light emitted from the LED lamp as illumination light.
