Abstract: A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide.

Abstract translation: 作为灯具的光导。 灯具包括至少一个固态光源，例如LED，以及被配置为接收来自固态光源的光的光导。 来自光源的光被耦合到光导中并通过全内反射在其内传输，直到光离开光导。 光导的形状引起并引导光的提取，并且还可用于产生提取的光的特定图案。 这种形状包括线性楔形物和扭曲的楔形物。 光导膜的光输入和输出表面可以包含光学膜。
