Spa Fixture Lighting System with Light Reflection Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spa fixture lighting systems lack uniform and aesthetically pleasing lighting solutions for accentuating spa fixtures such as hydrotherapy jets and control panels, with existing designs often resulting in uneven light distribution and limited decorative options.
Innovation Solution
A spa fixture lighting system incorporating a wall-fitting nut with a light reflection cavity and a light transmissive gasket or pipe, which diffuses light from discrete sources on the backside of the spa shell wall for uniform and decorative lighting on the front side, utilizing LED sources and flexible cables or disks for enhanced illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If discrete light sources are used directly on the front side of the spa shell wall, then the lighting structure is simple, but the light distribution is uneven and lacks aesthetic appeal
Solution Approach 1:
A light diffuser is introduced as an intermediary component between the discrete light sources and the spa shell wall. The diffuser scatters the light from the discrete sources to create uniform illumination across the front side of the shell wall, eliminating the uneven light distribution while maintaining the simplicity of using discrete light sources.
Solution Approach 2:
The lighting system transitions from direct front-side mounting to a back-side mounting configuration with light guides extending to the front. This dimensional change allows light sources to be positioned on the backside of the shell wall while achieving uniform front-side illumination through the light guide structure.
2Illumination intensity
If light sources are mounted on the backside of the spa shell wall, then uniform light distribution is achieved, but the installation and maintenance becomes more difficult
Solution Approach 1:
The lighting system is segmented into modular components: discrete light sources, light guides, and diffusers. This segmentation allows for independent installation, replacement, and maintenance of each component. The light sources can be accessed and replaced without dismantling the entire system, easing maintenance operations despite the backside mounting configuration.
3Illumination intensity
If a light reflection cavity is added to the wall-fitting nut, then light uniformity is improved, but the device complexity increases
Solution Approach 1:
The wall-fitting nut is designed to serve multiple functions: mechanical fastening of the light source and integration of the light reflection cavity. By combining these functions into a single component, the overall device complexity is minimized while still achieving the light uniformity benefits provided by the reflection cavity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides more uniform and aesthetically appealing accent lighting for spa fixtures by diffusing light from discrete sources, enhancing the visual appeal of spa fixtures and creating a more immersive experience.
Implementation Method 1
a light reflection cavity disposed between the wall-fitting nut, wall fitting and the spa shell wall and positioned to receive light emitted by the light source
Implementation Method 2
a light transmissive gasket or pipe, which diffuses light from discrete sources on the backside of the spa shell wall for uniform and decorative lighting on the front side
Implementation Method 3
a light pipe in direct optical communication with the light reflection cavity and extending through a spa shell wall so that light emitted from the light source and received by the light reflection cavity is introduced to the light pipe for transmittance of the light through the light pipe
