1. A lighting device, comprising:
- a housing;
a light source including multiple light emitting diodes (LEDS);
multiple lenses, wherein there are less lenses than LEDS; and
a support member that supports the multiple lenses relative to the LEDS in the housing, wherein each of the lenses corresponds to a different one of the LEDS;
wherein, for each LED with a corresponding lens, the corresponding lens is arranged with respect to a light path of the LED so that substantially all light emitted by the LED traverses only its corresponding lens, and a substantial amount of light emitted by at least one of the LEDs without a corresponding lens does not traverse any of the lenses.

Abstract
A lighting device includes a housing, multiple light emitting diodes (LEDS), and multiple magnifier lenses. The multiple LEDS and the multiple magnifier lenses are located in the housing. Each of the magnifier lenses corresponds to a different one of the LEDS, and there are less magnifier lenses than LEDS. Each LED that has a corresponding magnifier lens is arranged with respect to its magnifier lens so that substantially all of the light emitted by the LED only traverses its corresponding magnifier lens. At least one of the LEDS emits light that does not traverse any of the multiple magnifier lenses.

11. A lighting device, comprising:
-
a housing; first and second light emitting diodes located in the housing; a first magnifier lens arranged in a light path of the first light emitting diode that focuses a first light beam of the first light emitting diode onto a target area, wherein substantially all of the first light beam traverses the first magnifier lens; a second magnifier lens arranged in a light path of the second light emitting diode that focuses a second light beam of the second light emitting diode onto the target area, wherein substantially all of the second light beam traverses the second magnifier lens, and wherein substantially all of the first and second light beams only illuminate the target area; a third light emitting diode located in the housing, wherein the third light emitting diode generates a third light beam that does not traverse a magnifier lens; and a support member that respectively supports the first and second magnifier lenses relative to the first and second light emitting diodes. - View Dependent Claims (12, 13, 14, 15, 16)
