An illuminating brick includes a block and at least one light-emitting element mounted in the brick. The brick has a top face, a bottom face and a plurality of lateral side surfaces interconnecting the top and bottom faces. The at least one light-emitting element is engaged in and optically coupled to at least one of the bottom face and lateral side surfaces. The lateral side surfaces and the bottom face are configured for reflecting and directing light emitted from the at least a light-emitting element to exit through the top face.

Illuminating brick

A planar illumination device includes at least one light source, a housing structure, at least one light guide plate, and at least one light exiting surface. The at least one light source is received in the housing structure. The housing structure includes at least one light emitting surface through which the light emitted from the at least one light source exits the at least one housing. The at least one light guide plate includes at least one light incidence surface through which the light enters into the at least one light guide plate, and contacts with the at least one light emitting surface. The light exits the at least one light guide plate through the at least one light exiting surface. The at least one light exiting surface includes a plurality of continuously connected bulge points formed thereon.

Planar illumination device

A light emitting diode (LED) illumination device () includes an LED (), a frustum-shaped light guide member () and a light diffusing plate (). The frustum-shaped light guide member () has a light input surface () and a light output surface () opposite to the light input surface (). The light guide member () tapers from the light output surface () to the light input surface (). The light input surface () is optically coupled to the LED (), and the light diffusing plate () is optically coupled to the light output surface () of the light guide member ().

Light emitting diode illuminating device

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.
