Problem
The existing delineator systems require complex setting operations to achieve the visual recognition of moving lighting positions along roads, as they need to synchronize the on and off timings of light emitting devices based on their arrangement order, making it difficult to implement effectively.
Innovation Solution
A control device and method that includes an information collection unit, arrangement order determination unit, and lighting control unit to collect device information, determine the arrangement order, and transmit start times to light emitting devices, allowing them to repeat a defined lighting pattern, simplifying the process of creating the illusion of moving lighting positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the timings of turning on and off each light emitting device are set to be shifted in arrangement order to provide visual recognition of moving lighting position, then the visual recognition effect is improved, but the setting operation becomes very complicated
Solution Approach 1:
The control device automatically determines the arrangement order of light emitting devices by collecting device information and autonomously calculates the start times for each device based on the determined arrangement order. This self-service approach eliminates the need for manual timing configuration, resolving the contradiction between achieving visual recognition effects and maintaining ease of operation.
2Manufacturing precision
If manual setting of timing for each light emitting device is performed to achieve lighting pattern according to arrangement order, then the lighting pattern accuracy is improved, but the operational complexity increases significantly
Solution Approach 1:
The control device performs preliminary actions by automatically determining the arrangement order of light emitting devices before calculating and setting the start times. This preliminary determination of arrangement order based on collected device information enables accurate lighting patterns without requiring complex manual timing adjustments, thus maintaining precision while reducing operational complexity.
Solution Approach 2:
The control device collects device information from light emitting devices and uses this feedback to automatically determine the arrangement order and calculate appropriate start times. This feedback mechanism ensures accurate lighting patterns are achieved through automated calculation rather than manual setting, resolving the contradiction between precision and operational complexity.

AI summary
A control device controls a plurality of light emitting devices, and includes: a controller that: collects device information from the light emitting devices that are repeatedly turned on and off in a lighting pattern, wherein a turn-on period and a turn-off period are defined within a cycle in the lighting pattern; determines an arrangement order of the light emitting devices based on the device information; calculates a start time at which each of the light emitting devices starts repetition of the lighting pattern using the arrangement order; and transmits lighting information including the start time to each of the light emitting devices and causes each of the light emitting devices to start the repetition of the lighting pattern.
