Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting fixtures using LEDs lack flexibility and customization options, as they are designed to produce only a single beam type, requiring modification or replacement of optics for different applications, and offer limited adjustability to accommodate changes in target areas or lighting needs.
Innovation Solution
The development of adjustable lighting fixtures with modular components, including solid state light sources, positioning rings, and optical elements, allowing for the creation of customizable composite beams from a small number of fixture components, enabling on-site adjustments and changes to achieve desired beam patterns and lighting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed optics are used in LED fixtures to produce a specific beam distribution type, then the beam pattern is well-defined and standardized, but the fixture lacks flexibility and requires modification or replacement of dozens of optics to change beam types
Solution Approach 1:
The fixture divides the light source array into multiple independently controllable groups, where each group can be individually adjusted for intensity and timing. This segmentation allows the same physical fixture to produce different beam distribution patterns by controlling different subsets of LEDs, eliminating the need to physically replace optics for different beam types.
Solution Approach 2:
The system implements dynamic control of LED intensity through pulse width modulation (PWM) and dimming circuits, allowing the beam pattern to be changed in real-time without physical modification. The fixture can dynamically adjust which LEDs are active and at what intensity levels, enabling transition between various beam distribution types during operation.
2Adaptability or versatility
If custom beam patterns are created using multiple individual LEDs with separate optics, then beam customization is possible, but the device complexity and number of components increase significantly
Solution Approach 1:
Multiple LEDs are mounted in close proximity within a single fixture housing, merging what would traditionally require multiple separate fixtures into one integrated unit. The shared power supply, control circuitry, and housing reduce overall system complexity while maintaining the ability to create customized beam patterns through electronic control of individual LED groups.
Solution Approach 2:
The fixture is designed as a universal platform that can produce multiple beam distribution types (spot, flood, asymmetric, customized patterns) using the same physical components. By programming different intensity combinations and timing sequences for the LED groups, a single fixture performs the function of what would otherwise require multiple specialized fixtures with different optics.
3Reliability
If traditional lighting fixtures are designed for a single beam type, then the optics are optimized for that specific pattern, but any change in target area or lighting needs requires fixture replacement
Solution Approach 1:
The system changes the operational parameters of the LED array rather than the physical optics. By adjusting intensity ratios, timing sequences, and activation patterns of different LED groups, the fixture produces different beam distribution patterns while maintaining consistent optical quality. This parameter-based approach allows adaptation to different target areas and lighting needs without replacing the fixture hardware.
