摘要:
Certain disclosed embodiments use two substantially hemispherical illumination sources, mounted on a mount that allows the illumination sources to illuminate both sides of the reflector, allowing both halves of the reflector, with 2 pi rotation, to be used for generating the lighting distribution. This system and method both increases the amount of light collected and increases the efficiency of the illumination source.

Dual-direction collimation and a dual-direction optical collimator provide dual-direction collimated light at a non-zero propagation angle. The dual-direction collimator includes a vertical collimator configured to collimate light in a vertical direction and a horizontal collimator configured to collimate the vertically collimated light in a horizontal direction. The horizontal collimator is located at an output of the vertical collimator. A three-dimensional (3D) display includes the dual-direction collimator, a plate light guide and an array of multibeam diffraction gratings at a surface of the plate light guide to couple out the dual-direction collimated light guided in the plate light guide as a plurality of light beams corresponding to different 3D view of the 3D electronic display.

Provided is a solar light concentrating system which realizes suppression of power generation costs by applying a receiver 2 that is capable of suppressing a manufacturing cost to a low level, facilitating recovery work when a failure occurs, and quickly recovering a heating medium circulating inside in case of an emergency. The receiver 2 is formed by three-dimensionally combining multiple modules 20. At least a part of the modules is a trapezoid-shaped module 20B. The trapezoid-shaped module includes an upper header 21B, a lower header 22B being shorter than the upper header, and multiple heat receiving tubes 23 which connect the two headers. The heat receiving tubes are formed by successively altering their cross-sectional shapes in a way that makes each heat receiving tube shaped like a wedge that becomes narrower from its top toward its bottom in a front view, and like a wedge that becomes wider from its top toward its bottom in a side view.
摘要:
Devices and methods for curing materials with radiant energy are described. The devices include a first reflector and a second reflector that are semi-ellipses. The ellipses that define the first reflector and the second reflector have axes of different lengths, and the reflectors are aligned such that the focal points of the reflectors are overlaid. A radiative energy source at a near focal point of a reflector can provide energy to cure a coating on a substrate at a far focal point of the reflector. The different sizes of the two reflectors decrease focusing error of the radiative energy and provide improved efficiency to the curing system.
