摘要： The present invention provides an LED tube (200a) for retrofitting into a fluorescent tube lighting fixture. The LED tube (200a) comprises at least one light emitting diode (201) and a longitudinal light guide (203) with two opposite ends. The at least one light emitting diode (201) is located at at least one of the opposite ends of the longitudinal light guide (203) and is arranged to inject light thereto. The longitudinal light guide (203) has a refractive pattern (206) formed on a longitudinal surface thereof, which pattern (206) is arranged to out-couple light from within the light guide (203). During operation, light emitted by the light emitting diode (201) travels within the light guide (203) by total internal reflection, before being out-coupled from the light guide by the refractive pattern (206). Since the light emitting diode is not directly visible through the light guide, there is no risk that during operation, the light emitting diode will be a source of glare, or be able to cast sharp shadows. This allows the plurality of light emitting diodes within a conventional retrofittable LED tube to be replaced with a smaller number of individually brighter light emitting diodes, which can together provide the same illuminance as such a conventional retrofittable LED tube, but at a reduced cost of production and with increased reliability, due to the presence of fewer components. Moreover, the refractive pattern (206) on the light guide can be altered to suit different applications and to provide different patterns of illumination, as required. The invention also provides a luminaire comprising such a new type of retrofittable LED tube, as well as a backlight unit for a display, wherein the backlight unit comprises such a new type of retrofittable LED tube. In addition, the invention provides a method of manufacturing such a new type of retrofittable LED tube which comprises moulding the light guide from a polycarbonate, or acrylate polymer, such as poly(methyl methacrylate). Finally, the invention also provides a method of reducing electrical power consumption by retrofitting a pre-installed fluorescent tube lighting fixture with such a new type of retrofittable LED tube.

摘要： Time-multiplexed backlighting includes a time-multiplexed light source to provide a light beam having a first non-zero propagation angle during a first time interval and a second non-zero propagation angle during a second time interval. A time-multiplexed backlight includes a light guide configured to guide the light beam and a diffraction grating configured to coupled out a portion of the guided light beam with a different principal angular direction in each of the first time interval and the second time interval. A multiview display includes the time-multiplexed light source and a multibeam backlight to provide coupled-out light beams during each of the first and second time intervals, wherein the principal angular directions of the coupled-out light beams correspond to different view directions of the multiview display.
