A light emitting diode illuminator includes a reflecting shell (), a light emitting diode light source () and a transparent cover (). The reflecting shell includes a plurality of sequentially connected hollow tapered bodies () having different taper angles. The tapered bodies cooperatively form a receiving space (). The light source is installed at an end of the receiving space. The transparent cover is disposed at an opposite end of the reflecting shell away from to the light source and configured for directing light emitted from the light source out from the light emitting diode illuminator.

LED illuminator

A lighting apparatus includes a reflector, a light source, and a lens unit. The reflector has an open side, and a reflective surface that extends from a periphery of the open side and that defines a compartment. The light source is disposed in the compartment and emits light toward the reflective surface. The reflective surface reflects the light from the light source towards the open side. The lens unit is disposed to close the open side and permits passage of the light reflected by the reflective surface therethrough. The lens unit includes a central lens portion, and first and second side lens portions respectively disposed on two sides of the central lens portion. The central lens portion and the first and second side lens portions are Fresnel lenses, and are configured to redirect the light passing therethrough to result in rectangularly-distributed illumination outwardly of the lighting apparatus.

Lighting apparatus

A backlight module () includes a plurality of illumination devices (). Each of the illumination devices includes a light guide block () and a point light source () optically coupled with the light guide block. The light guide block includes a light exit surface (), a bottom surface () opposite to the light exit surface, and a tapered portion () located between the light exit surface and the bottom surface. The bottom surface has a receiving hole () formed therein. The tapered portion includes an outside surface () and a prism array () formed on the outside surface. The point light source is secured in the receiving hole. The plurality of illumination devices are joined with one another and the light exit surfaces of light guide blocks are substantially coplanar and whereby cooperatively constitute a light output surface of the backlight module.

Light guide block and related illumination device and backlight module having the same

An exemplary billboard includes a backlight module, a light transmissive canvas, a pattern layer and a light converging layer. The light transmissive canvas is adjacent to the backlight module. The light transmissive canvas includes a first surface facing the backlight module and a second surface opposite to the first surface. The pattern layer is formed on the second surface. The light converging layer covers the pattern layer and comprises a plurality of microstructures formed thereon distal from the light transmissive canvas.
