  • Patent number: 7374327
    Abstract: A flat planar light fixture formed of a translucent panel with for the transmission of light is illuminated by a plurality of high brightness LEDs disposed along the edges thereof. A layer of reflective material on a back surface of the panel facilitates reflection and dispersion of light that occurs within the panel through a front surface thereof. The LEDs are powered by low-voltage direct current and coupled with an emergency backup battery that is maintained in a charged condition by household current. The light fixture may be operatively connected with a signal receiver that controls the light intensity and turns the LEDs on and off responsive to signals transmitted from a remote signal transmitter. The LEDs may be provided in different colors to allow the user to vary the color of illumination. The light fixture may also be operatively connected with an alarm system.

  • Patent number: 7309154
    Abstract: A surface light source device for illuminating a displaying member of a display comprises a light guide plate and primary light source. Primary light enters into a first guiding portion through an end face (incidence face) thereof extending in an extending direction, then inner-propagating and entering into any second guiding portion gradually meantime. A major part thereof is inner-reflected by an inner-reflection face (first side face) to be directed to a guiding-emitting-portion, then being outputted from an emission face gradually. The first side face makes a sharp angle ? with respect to the extending direction at a portion connected to the guiding-emitting-portion. Second guiding portion has a second side face which is located on a side nearer to the incidence face and makes a sharp angle greater than ? at a portion connected to the first guiding portion.
