Multiple light emitting device modules illuminate multiple different directions, while avoiding deterioration of radiation efficiency by fins. In the lighting fixture 10 incorporating multiple light emitting device modules 1 each having fins 1e1 for radiating heat generated by the light emitting device 1a, the multiple light emitting device modules 1-1, 1-4, ... 1-8 are arranged in such a manner that a main optical axis line L1-1 of one light emitting device module 1-1 and main optical axis lines L1-4, L1-5, ... L1-8 of the any other light emitting device modules 1-4, 1-5, ... 1-8 form an angle of larger than zero degree, or are in skewposition, and the fins 1-1e1, 1-2e1, ... 1-8e1 are arranged in such a manner that all the fins 1-e1, 1-2e1, ... 1-8e1 are parallel with respect to a vertical plane and roots of the fins are positioned at the same level as or lower than tips of the fins. |
