Solution Overview
Problem
Conventional lighting is wasteful of energy and fails to optimize visual quality, particularly in localized activity areas, leading to issues like uneven illumination, glare, and veiling reflections, which compromise visual comfort and efficiency.
Innovation Solution
A lighting system that combines multiple lamp units with adjustable features such as spatial arrangement, aperture, focus, and direction, utilizing energy-efficient light sources like LEDs, to provide uniform and targeted illumination, minimizing energy consumption and eliminating glare and shadows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional lighting fixtures are used to illuminate localized activity areas, then the activity area receives illumination, but up to 90% of light energy is lost outside the activity area resulting in high energy consumption
Solution Approach 1:
The patent applies local quality by using multiple lamp units with different aperture sizes strategically positioned to provide different functions: larger aperture lamp units provide ambient illumination while smaller aperture lamp units provide focused task illumination. This localized optimization of light distribution ensures that light energy is delivered precisely where needed within the activity area, minimizing waste and reducing overall energy consumption by up to 90% compared to conventional lighting fixtures.
2Object-affected harmful factors
If lamp shades are used to reduce glare from light sources, then glare is ameliorated, but the lamp shades absorb and disperse a large fraction of light resulting in wasteful light distribution
Solution Approach 1:
The patent segments the lighting function by using multiple discrete lamp units instead of a single light source with a shade. Each lamp unit is positioned and oriented to provide specific illumination zones, eliminating the need for light-absorbing shades. The segmentation allows direct control of light distribution through positioning and aperture size rather than relying on shades that absorb and waste light energy.
3Illumination intensity
If a single large aperture lighting fixture is used to provide uniform illumination, then illumination uniformity is improved, but the fixture cannot be localized to specific activity areas resulting in wasted light distribution
Solution Approach 1:
The patent divides a large aperture lighting system into multiple smaller lamp units, each capable of being independently positioned and oriented. This segmentation allows the system to provide uniform illumination across activity areas while maintaining the ability to localize light delivery. Each lamp unit contributes to the overall uniformity while the modular structure enables precise positioning to avoid light waste outside the activity area.
Solution Approach 2:
The patent employs adjustable and reconfigurable lamp units that can be dynamically positioned and oriented to adapt to different activity areas and illumination requirements. This dynamic capability allows the system to optimize light distribution for uniformity while localizing illumination to specific areas as needed, preventing light waste and enabling energy savings when individual activity areas are not in use.
4Illumination intensity
If multiple lighting fixtures are used to illuminate different activity areas, then localized illumination is achieved, but individual fixtures cannot be turned off when individual activity areas cease to need illumination
Solution Approach 1:
The patent segments the lighting system into multiple independently controllable lamp units within a single fixture. Each lamp unit can be individually switched on or off, allowing users to illuminate only the specific activity areas that are currently in use. This segmentation provides both localized illumination and the energy efficiency of selective activation, eliminating the waste associated with illuminating entire areas when only portions are needed.

AI summary
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.
