Embodiment Construction

[0016] in figure 1 In the conventional indirect lighting system shown, the light source A, usually a high-intensity lamp suitable for producing a narrow beam, is hidden in a conical or parabolic reflector B. The narrower beam of light is shown by the periphery C, and this constitutes the main optical device of the indirect lighting system. It should be understood that the main optical system may also include lenses, protective screens and other devices. The secondary optical device D includes a large reflective surface E that is placed at a certain distance from the light source to cross the main beam C and redirect the light into the secondary beam F directed to an appropriate target. Such as figure 1 As shown, some of the main light G is lost without striking the reflector. It should be understood that the sub-reflector E is processed according to the appropriate degree of mirror reflection and formed into a shape suitable for the specific application. It should also be und...

Abstract

An indirect lighting system (80) adapted to direct light to a target, the system comprising: Primary optics arranged to eject a flat beam of uniform intensity light onto an assembly (87) of fractal reflector modules (25) that reflect the beam to the target, the primary optics comprising a light source (85) and a reflector of stepped facets located on the surface of a parabolic reflector (86) the shape and location of each facet being calculated to provide a uniform intensity flat beam.

Description

Technical field [0001] The present invention relates to indirect lighting systems, and more particularly to systems incorporating free-form reflectors. Background technique [0002] The indirect lighting system has been familiar to people for some years and basically consists of a main light source, the light of the main light source is guided to a reflector, and the reflector then directs the light to the target, thereby providing an indirect lighting system, whereby the light source is hidden But not directly. There are many reasons why these systems are used, including: reducing glare for aesthetic and safety reasons; improving the appearance of the lighting system; avoiding direct viewing of the light source, which is too strong to be viewed safely; and combining the light source and its The power supply is located away from the area that must be illuminated. [0003] The currently available indirect lighting systems encounter the following problems: the illuminance level is ...
