Abstract: Substrate-guided relays (100) that employ light guiding substrates to relay images from sources to viewers in optical display systems. The substrate-guided relays are comprised of an input coupler (110), an intermediate substrate (120), and an output coupler (130). In some embodiments, the output coupler is formed in a separate substrate that is coupled to the intermediate substrate. The output coupler may be placed in front of or behind the intermediate substrate, and may employ two or more partially reflective surfaces to couple light from the coupler. In some embodiments, the input coupler is coupled to the intermediate substrate in a manner that the optical axis of the input coupler intersects the optical axis of the intermediate substrate at a non-perpendicular angle.

Abstract: The present invention relates to lighting device (10). The lighting device comprises a light guide plate (12), and at least one array of light emitting diodes (LEDs) (14), which LEDs are accommodated in holes arranged in the light guide plate, wherein each hole has: at least two side facets (18) through which light from the LEDs is to be laterally coupled into the light guide plate, and at least one corner (20) formed by two converging side facets of the at least two side facets. This promotes TIR at adjacent light sources and therefore diminishes losses due to absorption or scattering at adjacent holes.

A planar light source device having an opening in the upper surface comprises a hollow box, a diffusion plate disposed in the opening, a reflecting plate disposed on the bottom of the hollow region of the box, and a plurality of point light sources disposed in a row along at least one side surface of the box. This planar light sources device is characterized by including a refracting element disposed parallel to the row of point light sources and between the point light sources and the hollow region for refracting the light from the point light sources, whereby the light at an incident angle at which the brightness is greatest in the luminous intensity distribution of the light radiated to the irradiation subject surface of the refracting element is refracted to the bottom surface of the box by the refracting element.
