    摘要: A display panel for a flat panel display includes a planar array of LCD devices and a planar array of LED devices that is closely spaced apart from the planar array of LCD devices, at least some of the LED devices being disposed within a periphery of the array of LCD devices such that, in operation, the planar array of LED devices provides backlighting for the planar array of LCD devices. The planar array of LED devices can include at least one solid metal block having first and second opposing metal faces. The first metal face includes therein an array of reflector cavities, and the second metal face includes therein heat sink fins that are exposed at the back face of the flat panel display.

    摘要: A light emitting diode (LED) component comprising a submount with an array of LED chips and a lens over the array of LED chips. A diffuser is arranged so that at least some light from the LEDs passes through the diffuser to mix the LED light in the near field. The light passing through the diffuser appears as a mixture of LED chip light when directly viewed. A lighting device is also disclosed comprising an LED component comprising an array of LED chips and a near field diffuser to mix at least some of the light from the LED chips in the near field. A remote reflector is included to reflect at least some the light from the LED component so that is emits from the lighting device in the desired direction.
