Delight Arrow
24-hour illuminated synchronous LED arrow board
The Delight Arrow is a synchronized LED arrow board designed for reliable traffic guidance during road construction, regardless of day or night. By employing patented technology called "Fully Charged Emission Mode" and high-brightness LEDs, it ensures high visibility even under strong sunlight during the day, while enabling continuous operation for over 10 days without sunlight with 24-hour illumination. Additionally, it features a large-capacity lithium iron phosphate battery and various automatic brightness adjustment functions, achieving both enhanced safety and reduced maintenance burden. This product is designed in accordance with the visibility regulations set forth in the Road Structure Ordinance by the Ministry of Land, Infrastructure, Transport and Tourism. Taking into account the required stopping sight distance of approximately 210 meters (depending on design conditions) under a design speed of 120 km/h, it ensures a maximum measured visibility distance of approximately 300 meters. It possesses performance that is visible even during the day from distances well exceeding the required stopping sight distance.
