Rotatable Lamp Holder Adjusts LED Color Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adjustable color temperature LED bulbs often compromise aesthetics due to protruding switch handles and require complex modifications to the lamp body for switch installation.
Innovation Solution
An LED lamp design featuring a rotatable lamp holder with a rotatable knob that adjusts color temperature, eliminating the need for external switches and preserving the bulb's original appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a toggle switch is used to adjust color temperature, then color temperature adjustment function is achieved, but the switch handle protrudes externally affecting aesthetics and requires drilling holes in the lamp body increasing structural complexity
Solution Approach 1:
The patent integrates the switch mechanism directly into the lamp holder structure. The lamp holder body serves dual functions as both the mechanical support for the LED module and the housing for the color temperature adjustment switch. This merging eliminates the need for separate switch components and external switch handles, thereby maintaining aesthetic appearance while achieving color temperature adjustment functionality.
Solution Approach 2:
The lamp holder is designed as a multi-functional component that simultaneously provides mechanical support for the LED module, electrical connection, and color temperature adjustment control. By incorporating the switch functionality within the lamp holder itself, the design achieves multiple functions through a single integrated structure, avoiding the need for additional external components that would compromise aesthetics.
2Adaptability or versatility
If toggle switches are installed on the lamp body, then color temperature adjustment is enabled, but the lamp's overall structure is disrupted and mold production complexity increases
Solution Approach 1:
The patent combines the switch housing function with the lamp holder body, creating a single integrated component. This integration means that the lamp holder is manufactured as one piece using existing mold processes, without requiring additional separate molds for switch housings or complex assembly operations. The unified structure simplifies the manufacturing process and maintains ease of production.
Solution Approach 2:
The lamp holder serves multiple functions including mechanical support, electrical connection, and control interface housing. By designing the lamp holder to accommodate the switch mechanism internally, the patent avoids the need for separate switch housing components and their associated mold production requirements. This multi-functional design maintains manufacturing simplicity while achieving color temperature adjustment capability.

AI summary
An LED lamp with a rotatable lamp holder for adjusting color temperature includes a bulb shell, a lamp holder, a light source assembly, and a driver circuit board. The bulb shell and the lamp holder are combined to form a sealed space for accommodating the light source assembly and the driver circuit board. The driver circuit board comprises a rotatable switch, and the rotatable switch is fixedly connected to a rotatable knob on the lamp holder through a rotating shell, which enables the rotatable knob to drive the rotatable switch to rotate by an external force.
