Faucet Illumination Device Uniform Light Diffuser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional faucet illumination devices typically provide discrete 'hot spots' of light rather than a uniform illumination, which can be aesthetically and functionally inadequate.
Innovation Solution
The design incorporates a diffuser made of translucent material positioned laterally outward from an opaque base, supporting a substrate with light emitters that diffuse light uniformly, and includes sensors to activate the light emitters based on ambient light and user presence, ensuring efficient and even illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single light source or discrete light sources are used in conventional faucet illumination devices, then the device structure is simple, but the illumination is non-uniform with discrete hot spots
Solution Approach 1:
The illumination device is segmented into distinct functional components: a base structure, a diffuser element, and a light source assembly. The diffuser is positioned as a separate component between the light source and the external environment, allowing each segment to perform its specific function optimally while contributing to overall uniform illumination
Solution Approach 2:
A diffuser element is introduced as an intermediary component between the discrete light sources and the external space. This diffuser mediates the light transmission, scattering the light from the discrete sources to create a uniform illumination pattern, thereby resolving the contradiction between simple device structure and uniform illumination
2Illumination intensity
If light emitters are positioned to provide broad illumination, then uniform lighting is achieved, but light intensity at specific areas may be insufficient
Solution Approach 1:
The light emitters are arranged with varying intensities and positions to create different local illumination qualities. The diffuser is strategically positioned to ensure that areas requiring more light receive adequate intensity while maintaining overall uniformity, optimizing energy use by distributing light where needed rather than uniformly across all areas
Solution Approach 2:
The system employs sensors to detect ambient light conditions and user presence, dynamically changing the illumination parameters (intensity, timing) accordingly. This allows the system to provide uniform illumination when needed while reducing power consumption during periods of sufficient ambient light or when no users are present
3Illumination intensity
If illumination is provided continuously, then uniform lighting is maintained, but energy consumption increases
Solution Approach 1:
The illumination device operates periodically rather than continuously, using sensors to detect user presence and activate lighting only when needed. The system transitions between active illumination states and standby states, maintaining consistency during active periods while significantly reducing overall energy consumption during non-active periods
Solution Approach 2:
Sensors provide feedback about ambient light conditions and user presence to the control system, which adjusts illumination accordingly. This feedback mechanism ensures consistent illumination when users are present while automatically reducing or eliminating illumination when not needed, optimizing the balance between illumination consistency and energy consumption

AI summary
An illumination device for a faucet includes an opaque base supported above a translucent diffuser. A plurality of light emitters is supported by a substrate intermediate the base and the diffuser, wherein light from the light emitters is transmitted through the diffuser and outwardly to provide a display of substantially uniform light.
