Controlled flaring light transmission device

摘要

Various exemplary embodiments relate to a light transmission device for transmitting light from at least one light source to an illuminated surface. The device may include at least one light entrance surface that allows entrance of light from the at least one light source; a light emitting surface with an area greater than the total area of the at least one light entrance surface; at least one light pipe portion extending from the at least one light entrance surface toward the illuminated surface wherein the light pipe portion internally reflects the light toward the illuminated surface; and a flared diffusion portion between the at least one light pipe portion and the light emitting surface wherein the diffusion portion internally reflects the light towards the light emitting surface. The device may be a solid piece of plastic. The light pipe portions may be curved to bend light toward the illuminated surface.
