LED Light Dual-Terminal Power and Signal Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional LED lights with two power connecting terminals pose a risk of electric shock during installation, as existing solutions with current detection units are prone to misjudgment and have complex circuit structures.
Innovation Solution
An LED light design with two power connecting terminals, where one terminal transmits power and the other receives control signals to manage the on/off of the power supply, ensuring that power is only supplied when both terminals are properly installed, thereby preventing electric shock.

Engineering Contradiction Analysis
1Reliability
If current detection unit is used in driving circuit to detect current flowing through load, then installation safety can be improved, but circuit structure becomes complicated and misjudgment risk increases
Solution Approach 1:
The patent extracts the power supply function from the signal transmission function by using two separate terminals: one terminal exclusively for power supply and another terminal exclusively for signal transmission. This separation eliminates the need for current detection units and complex control circuits, thereby simplifying the overall circuit structure while maintaining installation safety.
Solution Approach 2:
The patent segments the electrical connection into two distinct functional parts: power supply connection and signal transmission connection. By dividing the original unified power-signal terminal into separate terminals, the system achieves safer installation characteristics without requiring complex detection circuits.
2Use of energy by moving object
If both terminals are powered simultaneously, then power supply efficiency is improved, but electric shock risk during installation increases
Solution Approach 1:
The patent implements preliminary action by requiring proper installation confirmation at one terminal before enabling power supply at the other terminal. The control circuit first detects the installation state through the signal terminal, then subsequently activates the power terminal only after confirming safe installation conditions, thereby preventing electric shock while maintaining efficient power supply.
Solution Approach 2:
The patent introduces a control circuit as an intermediary between the signal terminal and power terminal. This intermediary verifies installation conditions through signal transmission before permitting power flow, thereby mediating between the need for efficient simultaneous powering and the need to prevent electric shock during installation.
Data Source
AI summary
The present disclosure provides an LED straight light including a light tube with two pins at both ends, an LED installed in the light tube and a driving circuit. The driving circuit includes a mains branch and a signal branch. The mains branch is coupled to the pins at one end of the light tube for transmitting power to the LED for power supply. The signal branch is coupled to the pins at the other end of the light tube for transmitting external driving signals to control the on/off of the mains branch. The LED straight light of the present disclosure is powered by two ends, one of the two ends supplies power to the LED through the mains branch, and the other end receives driving signals to control the on/off of the mains branch.
