Solution Overview
Problem
Conventional mood lights lack the ability to autonomously adjust their color to match the environment or target, relying on default settings and requiring additional control systems, and their operation is often hindered by slow and inaccurate contact switches.
Innovation Solution
A lighting module with a deformable elastic portion, a pressure sensor, and a color detecting unit that generates a color signal based on pressure changes, allowing the light emitting unit to automatically adjust its color without an external control system, using a processing unit to control the light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact switch is used for selecting color or enabling operation mode, then the device can be controlled, but the response speed is slow and contact reliability is poor
Solution Approach 1:
The patent replaces the mechanical contact switch with a capacitive touch sensor that detects changes in electrical capacitance when a user touches the elastic portion. This eliminates mechanical wear and contact reliability issues while providing fast, contactless operation with immediate response.
2Adaptability or versatility
If the lighting module can automatically detect color and adjust itself, then the user experience is improved, but the device complexity increases
Solution Approach 1:
The elastic portion serves multiple functions: it acts as a structural housing, a capacitive touch sensor for user input, and a visual indicator displaying the selected color. This multi-functionality eliminates the need for separate display components and control interfaces, reducing overall device complexity while maintaining automatic color adjustment capability.
Solution Approach 2:
The patent combines the housing structure with the display function by making the elastic portion itself emit light to show the selected color. This merging of structural and functional elements reduces the number of components needed while enabling automatic color detection and adjustment.
3Adaptability or versatility
If conventional mood lights provide limited colors with default selections, then the device complexity is low, but the adaptability to environment or target is poor
Solution Approach 1:
The lighting module autonomously detects colors in the environment or on targets using its color sensor and automatically adjusts its emitted color to match. This self-service capability eliminates the need for complex control systems or user intervention while providing extensive color adaptability.
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
Enables rapid and accurate color adjustment of the light to match the environment or target, enhancing user experience by eliminating the need for additional control systems and improving operational speed and accuracy.
Implementation Method 1
The elastic portion has an internal space. By applying a force, the elastic portion can be deformed so as to result a color transformation signal.
Implementation Method 2
The color detecting unit receives the color transformation signal and is initiated based on the color transformation signal for detecting a color of a target to generate a color signal.
Implementation Method 3
The light emitting unit is disposed in the elastic portion, and emits a light corresponding to the color signal.

AI summary
A lighting module with variable colors (1, 2) includes an elastic portion (11), a pressure sensor (12), a color detecting unit (13), and a light emitting unit (14). The elastic portion has an internal space. By applying a force (F), the elastic portion can be deformed so as to generate a pressure change of the internal space. The pressure sensor is coupled to the internal space of the elastic portion, and detects the pressure change of the internal space to output a color transformation signal (S 1 ). The color detecting unit is coupled to the pressure sensor. The color detecting unit receives the color transformation signal and is initiated based on the color transformation signal for detecting a color of a target to generate a color signal (S 2 ). The light emitting unit is disposed in the elastic portion, and emits a light corresponding to the color signal. In addition, a lamp (L) with the lighting module with variable colors is also disclosed.
