Separate Lamp Control Circuit for Dual White Light Strings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart lamp products face challenges with high costs and complex maintenance due to internal controllers, multiple control circuits, and lengthy wires, which complicate operations and increase costs.
Innovation Solution
An independent and separate control circuit using two control chips and transistors to separately control bright white and warm white light-emitting circuits, reducing circuit complexity and costs while enabling grouped control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the controller is arranged inside the lamp, then the control function is integrated, but when the controller breaks down, the whole lamp has to be changed because it is inconvenient to change and maintain the controller separately, leading to a higher cost
Solution Approach 1:
The control circuit is segmented from the lamp body into separate modules. The control circuit board can be independently removed and replaced without changing the entire lamp, enabling separate maintenance of the controller while keeping the lamp body intact.
Solution Approach 2:
The controller is extracted from the internal structure of the lamp and placed on a separate control circuit board that can be independently accessed. This allows the controller to be taken out for maintenance or replacement without disassembling the entire lamp assembly.
2Adaptability or versatility
If several separate control circuits are configured to realize control of the lamp, then different portions of the lamp can be controlled separately, but because the controller is arranged outside the lamp, there will be many wires between a lamp body and the controller, and the wires are relatively long, leading to an increase in cost
Solution Approach 1:
Multiple separate control circuits are merged into a single integrated control circuit board that can control different lamp portions through internal circuit routing. This consolidation reduces the number of external wires needed while maintaining the separate control capability for different lamp sections.
Solution Approach 2:
The control circuit board is designed with multi-functional capabilities to control multiple lamp portions (upward light, downward light, different color temperatures) through a single unified interface, eliminating the need for separate control circuits and reducing wire complexity.
