| 摘要 |
Lighting fixtures, systems, and methods of using the lighting fixtures that can achieve radically increased energy efficiency and visual effectiveness, are disclosed. The invention also offers the potential for decorative effects, supplementary background lighting, and other lighting effects. Various embodiments use light sources capable of individual focus, replacement, and control of operation. Fixtures allow mounting of the light emitting components to achieve a large effective aperture/diameter of the fixture in relation to the distance from the illuminated area, producing improved illumination. The light emitting components may be installed on parts of the fixture that may be oriented individually, thereby allowing infinite and/or incremental adjustment of the overall light emission pattern to achieve desirable illumination effects. Desirable lighting effects are further achievable by selection of the lighting type (LED, incandescent, fluorescent, etc), combinations thereof, and by selection of the fixture aperture/diameter, axis, and intensity. Shielding of the light sources to avoid glare to bystanders may be included.
