Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exterior lighting installations face challenges in accommodating various lighting configurations, such as different beam angles, light output, and colors, without compromising the water-tight integrity of fixtures or requiring specialized tools, and existing solutions often result in exposure to dirt and water, leading to reliability issues.
Innovation Solution
A water-tight LED light assembly with a rotatable beam angle dial and interchangeable accessories like shrouds, cross louvers, and snoots, allowing for adjustable beam angles and light output without disassembly, and enabling changes in lighting configurations without compromising the fixture's integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If field adjustments are made by disassembling light fixtures to change beam angles or replace components, then lighting configurations can be changed, but the water tight integrity of the fixture is compromised and reliability decreases
Solution Approach 1:
The patent implements a rotatable beam angle dial that dynamically adjusts the beam angle without requiring disassembly of the fixture. The dial mechanism allows the light emitter to be repositioned within the sealed housing, changing the light distribution pattern from spot to flood while maintaining the water tight seal intact throughout the adjustment process.
Solution Approach 2:
The fixture incorporates multiple NEMA light distribution patterns (spot, flood, and intermediate angles) within a single sealed unit. By integrating various beam angles and color temperature options (2700K, 3000K, 5000K) into one universal fixture design, the system eliminates the need to open the fixture for reconfiguration, thereby preserving reliability while achieving versatility.
2Adaptability or versatility
If field adjustments are made by disassembling light fixtures, then lighting configurations can be changed, but specialized or expensive tools are required and operation becomes complex
Solution Approach 1:
The beam angle dial is designed to be manually operated by the installer without requiring any specialized tools. The simple rotary dial interface allows field personnel to adjust beam angles and select color temperatures through direct hand operation, making the fixture self-adjustable and eliminating dependency on expensive specialized tools or complex disassembly procedures.
3Adaptability or versatility
If field adjustments are made by disassembling light fixtures, then lighting configurations can be changed, but the process is time-consuming and reduces productivity
Solution Approach 1:
All beam angle adjustments and color temperature selections are pre-engineered into the fixture with external access controls. The beam angle dial and color temperature selector are positioned for easy field access, allowing installers to make configuration changes immediately during installation without time-consuming disassembly, testing, or reassembly procedures.

AI summary
LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are flood lights. The light fixtures in at least some embodiments include power control features. In flood light embodiments beam angle and power or light output distribution can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. The light fixtures also support tilt angle adjustments and light fixture head adjustments. Beam distribution pattern can also be changed in some embodiments as well as power control. Beam distribution pattern, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.
