摘要: An LED lamp that includes a housing forming an open cavity, a plurality of LEDs configured to produce a light output disposed in the cavity, a lens disposed over the LEDs for focusing and/or diffusing the light output, and a redirection shield disposed in the cavity. The redirection shield includes a base plate with a plurality of apertures formed therein, and a plurality of shielding plates extending from a top surface of the base plate. The LEDs extend through the apertures. The shielding plates block a portion of the light output such that an overall light distribution of the light output from the LED lamp is asymmetric.

摘要: A projector includes a display screen, an imaging system adapted to provide an optical image, a reflector arranged on a transmission path of the optical image, and an optical transmission medium disposed inside the refraction space. The refraction space is formed between the reflector and the display screen. The optical image travels through the optical transmission medium by the reflection of the reflector and is transmitted to the display screen. A refractive index of the optical transmission medium is not equal to one.
