Car LED Light Color Temperature Change Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car lights with color temperature change units are bulky due to the need to lift or turn the color temperature change unit, making them unsuitable for compact designs when using LEDs as a light source, which contradicts the demand for smaller, cost-effective solutions.
Innovation Solution
A car LED light design featuring a lamp holder with a concave trough and an LED module, where a color temperature change unit with a drive member and light filter is positioned close to the LED module, allowing the light filter to be selectively moved within the beam angle of the LED's direct light, enabling full filtration or no filtration to change color temperature, thus simplifying the structure and reducing size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a color temperature change unit is added to an LED car light, then the color temperature can be changed, but the size of the car light increases
Solution Approach 1:
The light filter is nested within the beam angle θ of the LED module, allowing the color temperature change unit to be integrated into the existing LED structure without increasing the overall size. The filter is positioned to be selectively movable within the confined space of the LED beam angle.
Solution Approach 2:
The light filter is designed to be selectively movable between two positions: within the beam angle θ (to filter light and change color temperature) and outside the beam angle θ (to allow direct light passage). This dynamic positioning enables color temperature adjustment without requiring a bulky fixed structure.
2Adaptability or versatility
If the light filter is positioned to block the opening fully, then the light can be fully filtered, but the structure becomes more complex
Solution Approach 1:
The function of blocking and filtering light is extracted from a complex mechanical assembly and simplified to a single light filter element that can be selectively positioned. The filter is moved directly within the beam angle θ without requiring complex lifting or turning mechanisms.
Solution Approach 2:
Instead of moving a large cover or assembly to block the opening, the invention inverts the approach by moving a small light filter element directly within the beam angle θ. This reverses the conventional approach of blocking from the outside and achieves filtration with simpler, more compact mechanics.
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
This design allows for a compact, cost-effective car LED light that can change color temperature efficiently, meeting the demand for smaller form factors while maintaining functionality, by positioning the color temperature change unit directly in front of the LED module and using a drive member to control the light filter's position within the beam angle.
Implementation Method 1
The light filter is connected with the drive member and able to drive the light filter to move relative to the LED module... enabling the light emitted from the LED module to be first filtered by the light filter

AI summary
A car LED light capable of changing color temperature includes a lamp holder. A front side of the lamp holder is provided with a concave trough and formed with an opening. The lamp holder is provided with an LED module in the concave trough. The LED module has a beam angle θ. A color temperature change unit is provided in front of the LED module and includes a drive member. The drive member is connected with a light filter and drives the light filter to move relative to the LED module. Through the drive member, the light filter is selectively to be in front of the beam angle θ for changing the color temperature of the light emitted from the LED module; or the light filter is selectively to be away from the range of the beam angle θ for keeping the original color temperature of the light.
