Abstract:
1. A lamp reflector comprising: a reflecting cup having a trumpet-shaped structure having an enlarged end and a narrow end being opposite to the enlarged end, the reflecting cup having an axis passing through the enlarged end and the narrow end thereof, the enlarged end provided for projecting light beams and the narrow end provided for adapting to position a lamp, the narrow end gradually expanded toward the enlarged end, the reflecting cup having multiple tiers longitudinally formed thereon along the axis, each tier having a convex surface annularly formed on an inner periphery thereof, each convex surface axially curvilinearly extending from the narrow end toward the enlarged end and being convex toward the axis of the reflector cup for scattering light beams emitted from different angles, each convex surface and an adjacent convex surface of different tier curvature-discontinuously arranged to each other, each convex surface having multiple concave faces respectively radially formed thereon, each concave face axially extending from the narrow end to the enlarged end for condensing light beams emitted from different angles, each concave face being curvature-discontinuous to an adjacent concave face in the same convex surface.
