Problems solved by technology

This poses a problem because when multiple small light sources (e.g. LEDs) are put into the luminaire 4, a single shade may not be sufficient to redirect all spilled light back into the target area 5 or provide significant occlusion; This can produce uneven lighting, shadowing effects, or glare, which can be objectionable or potentially harmful (e.g. affecting field mobility)

Embodiment 1

[0027] Figures 2A-7B Specific examples of the above-mentioned modular devices are shown in . about Figures 2A-2F , the modular apparatus 12 may generally be considered to include a housing 22 formed to receive a shroud 23 and an enclosure 24 adapted to house a plurality of light sources 27 with associated optics 28 (see, for example, Figure 3A ). Outer lens 29 seals the open face of housing 24 (see Figure 2F )—for example, by gluing or tape—to protect the light source from dust, vandalism, or other undesired things, and may include an anti-reflective coating to maintain transmission efficiency if desired.

[0028] Shield 23 is formed from a highly reflective material (eg, aluminum machined to be highly reflective) and is attached to the inner surface (ie, the surface without fins) of housing 22; see Figure 2F . It should be noted that the shroud 23 may be screwed, glued or otherwise attached directly to the inner surface of the housing 22, or may be screwed, glued or o...

Abstract

A lighting fixture is presented comprising a plurality of modular apparatuses wherein each modular apparatus comprises one or more light sources and one or more light directing or light redirecting devices. Methods of adjusting one or more components of said lighting fixture about one, two, or three axes are presented whereby the lighting needs of a target area - even one of complex shape - may be addressed and in a manner that promotes compact fixture design with low effective projected area (EPA) without sacrificing transmission efficiency of the light sources.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to U.S. Provisional Application No. 61 / 492,426, filed June 2, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention generally relates to apparatus and methods for substantially illuminating a target area with one or more lighting fixtures. More specifically, the present invention relates to improvements in the design and use of lighting fixtures so that the steps of aiming and cutting off light projected from the lighting fixture can be separated without adversely affecting the size of the lighting fixture, In the case of effective projected area or efficacy, higher flexibility is obtained in solving the light requirements of special applications. Background technique [0004] It is well known that adequately illuminating a target area—especially one of complex shape—requires a combination of light-guiding (...
