    • A method and apparatus are disclosed for receiving light from one or more light sources, each of which comprises a substantially point-like light source. The received light is them emitted over an extended surface area including a first surface of an optical controller arranged to refract light received from at least one light source, a second surface of the optical controller arranged to reflect the light received from the first surface of the optical controller, the first surface and the second surface being arranged with respect to each other to enable total internal reflection of the light reflected from the at least one light surface, and a plurality of reflection elements located within the optical controller arranged to alter the path of the light traversing the optical controller so as to direct light out of the optical controller.
    • 公开了用于接收来自一个或多个光源的光的方法和装置,每个光源包括基本上点状的光源。 所接收的光在其延伸的表面区域上发射,包括布置成折射从至少一个光源接收的光的光学控制器的第一表面,光学控制器的第二表面被布置成反射从第一表面接收的光 光学控制器,第一表面和第二表面相对于彼此布置以使得能够对从至少一个光表面反射的光进行全内反射,并且位于光学控制器内的多个反射元件被布置成改变路径 的光穿过光学控制器以将光引导出光学控制器。
