Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal is transmitted through power lines in traditional direct-insert LED lamps, then the structure is simple, but signal stability deteriorates due to power supply interference
Solution Approach 1:
The patent divides the transmission function into separate channels: a power transmission line for electrical power and a separate signal transmission line for control signals. This segmentation isolates the signal transmission from power supply interference, improving signal stability while maintaining manageable structural complexity through dedicated function separation.
Solution Approach 2:
The patent introduces a separate signal transmission line as an intermediary channel between the control unit and LED lamps. This intermediary pathway allows signal transmission independent of the power line, mediating the separation between power delivery and control communication to eliminate power supply-induced signal interference.
2Quantity of substance
If traditional 2-wire carrier point-control is used, then the device is simple, but the maximum number of lamps that can maintain stable signals is limited
Solution Approach 1:
The patent segments the transmission medium into dedicated power lines and separate signal lines. This segmentation allows the signal transmission line to carry control signals without being overloaded or interfered with by power supply variations, enabling stable signal transmission to a larger number of lamps beyond the limitations of traditional 2-wire carrier systems.
3Reliability
If high-voltage color-changing point-control lamps use lamp strips with external control ICs, then signal stability improves, but cost increases
Solution Approach 1:
The patent extracts the control function from external control ICs and integrates it directly into the lamp structure through an onboard control unit. This extraction eliminates the need for expensive external control components while maintaining signal stability through the dedicated signal transmission line, reducing manufacturing cost while preserving reliability.
Solution Approach 2:
The patent merges the control unit and signal transmission functionality directly into the lamp assembly. By combining these functions within the lamp structure itself rather than using separate external control ICs, the design achieves cost reduction while maintaining the signal stability provided by integrated control architecture.

AI summary
The present disclosure provides a point-control lamp and a lamp string, wherein the point-control lamp includes a lighting component, a direct-insert LED support, and an injection-molded part. The direct-insert LED support includes a signal input part, a positive power connection part, and a negative power connection part. The lighting component includes a main control chip and multiple lighting chips. The lighting component is arranged inside the injection-molded part, and the direct-insert LED support passes through the injection-molded part and connects to the lighting component. The main control chip is electrically connected to the signal input part. The main control chip is also electrically connected to the positive power connection part, and the main control chip is also electrically connected to the negative power connection part. The lighting chips are electrically connected to the main control chip. The main control chip is configured to store a number address of the point-control lamp. Arranging a separate signal transmission line and matching with packaging addresses the issue of signal stability being affected by the power supply when the signal is transmitted through traditional power lines, thereby increasing the maximum number of lamps that can maintain stable signals, reducing costs, and improving user experience.
