Abstract
A lamp can includes: a first reflective surface which can be provided on a surface of a circular shaped member, a radius of a top of the annular member can be longer than a radius of a bottom of the annular member; a second reflective surface which can be arranged inside of the first reflective surface and can have a conical shape, a vertex of the second reflective surface can be directed to a top side of the first reflective surface; and a plurality of light emitters which can be annularly arranged on the first reflective surface around the second reflective surface at a predetermined interval so as to be projected on the second reflective surface.
Claims8
A lamp comprising:
- a first reflector including a concave reflective surface and a convex reflective surface with the convex reflective surface located at a bottom of the concave reflective surface;
- a second reflector wherein the first reflector is located inside the second reflector, and the second reflector includes a first reflective surface and a second reflective surface;
- a plurality of first light sources located between the first reflector and the second reflector, each of the plurality of first light sources having an optical axis directed outward with respect to a center of the lamp;
- and
- a lens located on the concave reflective surface, wherein
- (i) the first reflective surface of the second reflector is configured to direct light from at least one of the plurality of first light sources toward a portion of the lens corresponding to the first reflective surface, and
- (ii) the second reflective surface of the second reflector is configured to direct light from at least one of the plurality of first light sources through a portion of the lens corresponding to the first reflective surface to reflect off the convex reflective surface.
