Lighting device

A lighting device for use within a light box or light panel and comprising a housing with generally parallel upper and lower walls and diverging side walls with one or more LEDs disposed within the housing on a back wall thus to project light outwardly from the housing. Several such devices may be disposed within a light box or light panel to project light across the latter which light is then diffused before exiting from a front display panel or the like. The diffused light conceals the lighting devices within the light box or light panel. Such devices are intended to replace conventional fluorescent or neon lighting tubes or tungsten lights to produce substantially uniform light distribution by diffusion within the light box or light panel and incorporating low voltage and low power consuming light sources.
