ABSTRACT:
A lighting device (10) is provided which uses multiple LEDs to illuminate a target area. The lighting device includes first and second light emitting diodes (24, 26) spaced apart from each other. A first convex magnifier lens (34) is arranged in a light path of the first light emitting diode (24) for focusing light onto a target area. A second convex magnifier lens (36) is arranged in a light path of the second light emitting diode (26) for focusing light onto the same target area. The first and second magnifier lenses (34, 36) are supported relative to the first and second light emitting diodes (24, 26), respectively, by a cover (32).
