Abstract
A light apparatus includes one or more light pipes and/or diffusers to transfer and/or diffuse light from a few point light sources to a broader area and to other points. A hollow light pipe includes a light transmissive sidewall that encompasses an interior space, which receives and hides control circuitry for the light sources therein. A bottom end surface of the hollow light pipe is disposed adjacent to one or more light sources and transmits the light therefrom over a relatively large, uniform area. A solid core light pipe has a light receiving end and a light dispersion end having a reflective facet therein. The reflective facet includes a depression forming a reflective surface angularly displaced from a longitudinal axis of the solid core light pipe. A light diffuser surrounding a point source of light is adapted to cause the point source to look like a flame. A light apparatus including the hollow light pipe and the solid core light pipe and/or the light diffuser is adapted to provide a plurality of different light effects, including a multi-color light show through the hollow light pipe and a flame flicker effect through the solid core light pipe.
