Abstract
A lighting device having a dual LED point-source assembly containing two high flux LEDs mounted facing each other with LED lenses positioned between the LEDs. At least one heat sink is attached to one of the LEDs. The heat sinks serve to transfer heat from the LEDs to the outside environment. In one embodiment the lighting device is positioned within a fresnel lens to produce a horizontally uniform distribution of light.
Claims46
A lighting device comprising:
- (a) a stacked pair of LED modules, each LED module comprising an LED attached:
- to a thermally conductive mount on a first side and to an LED lens on a second opposed side, wherein the LED lens attached to one LED abuts the LED lens attached to the other LED;
- (b) a power source for providing electrical power to the stacked pair of LED modules;
- and
- (c) a hollow, approximately cylindrical member positioned around the stacked pair of LED modules.
