Abstract: A concave reflector can form a more uniform beam of light. The light source can be an LED with a nominally lambertian radiation pattern. LED can be high power requiring heatsink. Light reflected by reflector and light exiting without hitting reflector can form coinciding beams of essentially same size. Matching of sizes of reflected and unreflected components can be achieved in part by having a tangent at a rim parallel to axis of reflector. For some LEDs hot spot in center of beam is reduced by curvature becoming increasingly sharp when approaching along reflective curve a critical radius at which tangent to reflector curve in plane containing axis of reflector has angle near 45 degrees with respect to axis of reflector. Reflector can be used in, for example, work lights, desk lamps, accent lights, headlamps, and flashlights. Lamps can have multiple reflectors with one LED for each reflector.

Accordingly, the wide light pattern is refocused into a narrow beam pattern to improve the lighting efficiency. The distribution of the light output is regulated, and the heat generation is reduced.

An indicator lamp includes a light-emitting element 1 and a light-emitting element lens 2 having a light-emitting element mounting cavity 3 formed at the bottom, in which the light-emitting element disposed in the cavity 3 emits light to be fully reflected by the peripheral surface of the lens 1 and proceeds as emission light flux forwardly of the lens 1. The slope angle of the peripheral surface with respect to the lens axis is reduced progressively from the bottom toward the lens front surface 5 in three stages, thus forming circumferential corners 7 and 8 as boundaries between adjacent ones of the three stages. The circumferential corners scatter light emitted from the light emitting element 2 to provide concentric emission light fluxes as viewed from the side of the lens front.
