LED Landscape Spotlight Beam Angle Dial and Wattage Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exterior lighting installations face challenges in easily configuring lighting fixtures to vary beam angles, light output, and color without compromising the water-tight integrity of the fixtures or requiring specialized tools, as current methods often involve disassembly and exposure to dirt and water, leading to potential corrosion and reliability issues.
Innovation Solution
The development of an LED landscape spotlight with a beam angle changing dial and adjustable wattage control that allows users to change beam angles from 10 to 60 degrees and wattage from 2 to 16 without disassembly, using seals like silicone gaskets to maintain water-tight integrity and protect against dirt and water intrusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lighting fixtures are disassembled to change beam angles, light output, or color, then lighting configurations can be adjusted, but water-tight integrity is compromised and corrosion risk increases
Solution Approach 1:
The lighting fixture is divided into separate functional modules: a fixed sealed housing containing the LED light source, and removable external attachments including beam angle lenses, color filters, and diffusers. This segmentation allows users to change lighting configurations by swapping attachments without opening or disassembling the sealed housing, thus maintaining water-tight integrity while achieving adaptability.
2Adaptability or versatility
If lighting fixtures are disassembled for configuration changes, then beam angles and colors can be adjusted, but specialized tools and expensive equipment are required
Solution Approach 1:
The fixture incorporates dynamic, adjustable components such as rotatable lens holders that allow beam angle adjustment through simple rotation without tools, and snap-fit attachment mechanisms for color filters and diffusers that enable tool-free configuration changes. These dynamic design elements eliminate the need for specialized installation tools while maintaining versatility.
3Ease of operation
If field operations involve exposure to dirt and water, then lighting configurations can be changed on-site, but corrosion and reliability issues arise
Solution Approach 1:
The fixture employs flexible sealing elements including gaskets and membranes that maintain water-tight integrity while allowing for field configuration changes. These flexible sealing components accommodate the removable attachments and adjustment mechanisms without compromising the sealed environment, protecting internal electrical elements from dirt and water exposure during on-site operations.
4Illumination intensity
If light output and wattage are increased, then illumination intensity improves, but energy consumption increases
Solution Approach 1:
The fixture incorporates adjustable parameters including variable beam angle lenses that concentrate or distribute light to achieve different illumination intensities from the same light source, and controllable LED modules that allow wattage adjustment. Users can optimize the balance between light output and energy consumption by adjusting these parameters according to specific application requirements.

AI summary
Apparatus and methods for lighting. The apparatus may include an LED light source. The light source may be disposed in housing. The apparatus may include a circuit. The circuit may be configured to cause the LED light source to emit light at: a first intensity; and a second intensity that is different from the first intensity. The apparatus may include a mechanical power state selector. A user may use the power state selector to select between LED light sources that are arranged to illuminate in different directions. The apparatus may include a CCT state selector. A user may use the CCT state selector to select a CCT for one or more LED light sources. The CCT may be produced by combining light from one or more LEDs of different CCTs.
