Abstract: An LED device of the discrete type having a rectangular light emitting area suited for being arrayed with similar devices in contiguous relationship without optical cross-talk therebetween. An opaque but diffusely reflective housing of the device is molded of synthetic resin material with rectangular integral side walls defining a rectangular body. Their interior surfaces have peripheral upper and lower edges defining a principal cavity having a rectangular top opening. A pair of spaced electrodes extend through a bottom opening and have upper portions extending up into the cavity and there terminating so as to provide an electrode surface area below the top opening having a specularly reflective LED-containing cavity formed therein. An LED die within the electrode cavity is series-connected with the electrodes. Sloped inner walls of the body provide nonspecular reflection of light emitted from the LED.
