The utility model discloses a lighting device of light source, this light source produce heat in the relative direction of the direction of light with launching, dispose casing (2), and this casing (2) have including a plurality of light sources (4) in one of its surface including backup pad (3), this backup pad (3), still include radiator (5), and the location is in light source (4) of backup pad (3) surface is on the surface relative, forms its radiator (5) by the metallic structure who has recess (5b) the institute a plurality of fins of detached (5a), and every light source (4) set up in the calorifacient orientation of product of the fin (5a) of radiator (5), in one of recess (5b) at fin (5a) separately. The utility model discloses lighting device passes through the design of radiator structure, and the maximum efficiency of optimization radiator sets up the fin according to the position and the quantity of light source among the lighting device for every light source can all dissipate heat that their produced directly towards normal position in the fin with their unanimous positions. |
