Abstract
A lighting apparatus. The lighting apparatus comprises a light source, a hollow hollow module, and a rectangular lens. The hollow module has a concave, a opening, and an inner reflective surface. The light source is disposed in the concave. The rectangular lens with a semi-translucent incident surface and a display surface is seated in the opening. Light rays emitted from the light source are reflected by the inner surface. Subsequently, the light rays enter the incident surface and exit the lens through the display surface.
