Abstract:
1. An illumination device for providing light in an illumination direction, the illumination device comprising: a central body having a surface facing the illumination direction and including a first heat dissipating mechanism for allowing heat to dissipate through a central portion of the central body; first and second groups of Light Emitting Diodes (LEDs) connected to the central body directly or via an attachment feature, the first and second group of LEDs being spaced apart from each other; a second heat dissipating mechanism including one or more openings formed in the central body or in the attachment feature; a first reflector extending from the central body adjacent to the first group of LEDs for directing light from the first group of LEDs in the illumination direction; and a second reflector extending from the central body adjacent to the second group of LEDs for directing light from the second group of LEDs in the illumination direction, wherein heat generated by the first and second groups of LEDs is dissipated through the central body via the first heat dissipating mechanism, wherein the one or more openings of the second heat dissipating mechanism provide fluid flow cooling of the first and second groups of LEDs, and wherein one of the first and second heat dissipating mechanisms allows heat to dissipate between the first and second reflectors.
