Abrégé

A lens for an LED street lamp has an external curved surface that has a concave surface portion on one side thereof. A back surface of the lens has a micro -prism array and retainer feet. A recess in the back surface receives an LED light source. The outer surface of the lens has facets or windows that provide overlapping projections of light from adjacent facets. The lens is generally cushion shaped with an indentation at one side. The lens directs light in an asymmetrical distribution transverse to the lens and to direct light symmetrically over a wide area in a longitudinal direction of the lens.

Abrégé

A lighting apparatus comprises: an upper housing having a graduated stepped cylindrical profile, forming an upper portion of the lighting apparatus; a substantially annular heat sink having a round profile around its outer periphery and a hexagonal profile around its inner periphery, and being shaped so as to have an opening at the bottom of the heat sink; a plurality of LEDs located around the inner periphery of the heat sink, the LEDs being oriented so as to emit light in an upward direction at an angle; and a hexagonal reflector situated between the upper housing and the heat sink, the hexagonal reflector having a downwardly reflective lower surface. When the lighting apparatus is assembled and power is applied to the LEDs, light emitted from the LEDs is reflected off of the lower surface of the reflector so as to exit through the opening at the bottom of the heat sink.

Abrégé

A tray-shaped box body has, for example, a square bottom surface, an open upper surface, a light-reflecting member provided on an inner surface thereof, side walls inclined outward, and holes formed at least at two positions of the side walls near the bottom surface of the box body. LEDs are provided outside the holes, so as to emit light to an inner space of the box body. Protruding portions are formed at upper sides of the holes formed at the side walls of the box body, so as to extend from the side walls.
