Traffic Lamp Controller Power Signal Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic lamp control systems are complex due to the need for external control boxes and additional components to synchronize multiple lamps, which increases complexity and reduces accuracy in timing synchronization.
Innovation Solution
Integrating a controller within the traffic lamp to determine power signal characteristics and control light emission timing, allowing for more compact and accurate synchronization of light emitting elements without a separate remote control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a separate external control box is used to control multiple lamps, then the control function is achieved, but the system complexity increases
Solution Approach 1:
The controller is integrated directly inside the traffic lamp housing, merging the control function with the light emitting elements. This eliminates the need for separate external control boxes and reduces the number of connection wires, thereby reducing system complexity while improving timing synchronization accuracy through direct control of each lamp.
Solution Approach 2:
Each light emitting element is controlled by a separate controller unit within the traffic lamp, allowing independent timing control of each lamp. This segmentation enables precise timing synchronization without requiring complex external control systems, as each controller can be independently programmed and adjusted.
2Measurement precision
If multiple controllers are integrated within the traffic lamp, then timing synchronization accuracy is improved, but the device complexity increases
Solution Approach 1:
The traffic lamp is divided into multiple independently controllable units, each with its own controller. This segmentation allows each controller to manage a specific light emitting element with high precision timing, achieving overall synchronization accuracy without requiring a single complex centralized control system.
Solution Approach 2:
A common power signal serves as an intermediary reference for all controllers within the traffic lamp. Each controller uses this shared power signal to synchronize its timing operations, enabling coordinated control of multiple lamps without requiring complex communication protocols between controllers.

AI summary
A traffic lamp and a method of controlling the traffic lamp based on a power signal are provided. The traffic lamp can include a controller and a light emitting element When a plurality of light emitting elements is included in the traffic lamp, each light emitting element is coupled with a separate controller. Each controller can be configured to include a predetermined light emitting timing sequence for the corresponding light emitting element. When the power signal is supplied to the traffic lamp, each controller determines a power signal characteristic such as a frequency or a period of the power signal and controls a light output of the light emitting element: based on the power signal characteristic and the light emitting timing sequence. A plurality of light emitting elements can be synchronized using the power signal applied to the traffic lamp.
