Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light source modules in exhibitions, which use spotlights to display delicate items, face issues with color fading due to ultraviolet light emission, and require labor-intensive manual adjustments of colored shield plates to change color temperature, making it inconvenient and time-consuming to manage multiple spotlights.
Innovation Solution
A color temperature adjusting device using electrochromic devices integrated with a light source module and control module, allowing remote control of light sources to switch between warm and cool colors by controlling the electrochromic devices, which are composed of substrates, transparent electrode layers, and electrolyte layers, enabling efficient and simultaneous color changes across multiple light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual colored shield plates are used to adjust color temperature, then color temperature can be modified, but the operation becomes labor-intensive and time-consuming when multiple spotlights need adjustment
Solution Approach 1:
The patent replaces the mechanical manual adjustment system (physically mounting and removing colored shield plates) with an automated electro-optical system. Electrochromic devices are integrated into the spotlight structure, allowing color temperature adjustment through electrical control signals that change the optical properties of the electrochromic material, eliminating the need for manual mechanical intervention.
Solution Approach 2:
The system enables self-service operation where the spotlight automatically adjusts its color temperature based on control signals. The electrochromic devices are built-in and can be switched between different color temperatures (warm white, neutral white, cool white) through remote control or automated scheduling, without requiring human operators to manually intervene for each adjustment.
2Adaptability or versatility
If manual colored shield plates are used for color temperature adjustment, then color temperature can be changed, but the process requires mounting and removing plates one after another which is troublesome
Solution Approach 1:
The patent replaces the cumbersome mechanical process of mounting and removing shield plates with an electrical control system. The electrochromic devices are integrated into the spotlight housing and can be switched between different color temperatures instantaneously through electrical signals, eliminating the need for physical manipulation of separate components.
Solution Approach 2:
The patent merges the color temperature adjustment function directly into the spotlight structure by integrating electrochromic devices within the light source module. This combination creates a unified system where multiple color temperatures (warm white 2700K, neutral white 4000K, cool white 6504K) are available through a single integrated component rather than requiring separate shield plates to be attached and detached.
3Illumination intensity
If spotlights with ultraviolet light are used to display items, then delicate work of items can be highlighted, but the items are easy to fade in colors over time
Solution Approach 1:
The patent uses electrochromic devices that can change their optical transmission characteristics in response to electrical signals. These devices selectively transmit or block different wavelengths of light, allowing the spotlight to emit visible light for illumination while blocking harmful ultraviolet wavelengths, thus preventing color fading of displayed items while maintaining display effectiveness.
Solution Approach 2:
The patent changes the spectral parameters of the light emitted by the spotlight using electrochromic devices. By controlling the electro-optical properties of these devices, the system can adjust the light spectrum to eliminate ultraviolet components while preserving visible light output, thereby reducing photochemical damage to displayed artifacts while maintaining illumination quality.
