  • Reduction of construction cost : Don't require separate power supply cables
  • No dazzling : differentiated with previous products
  • Induce the safe drive by laminating automatically during the night and severe weather
  • it creates a safer and more pleasant mood by providing a beautiful scenery



│ INSTALLATION PLACE AND ENVIRONMENT │

  • boundaries of slanted roads, high-rick roads, mountain areas, crossroads, motorways, etc
  • Landscape lighting for parks & rest areas / Back side of buildings - areas without sunlight
  • General roads : Curves, landscapes, place without street lamps or security lights
  • Highways - Areas with frequent accidents (rest areas to shake of sleepiness, emergency parking space, High-pass entrance, tunnel entrance, areas with frequent fogs
  • entrance/exit of service areas, parking lots, exit sign, information signs, etc.

>> Installed to prevent major fall accidents

Tragedy of bus fall accident at Incheon Bridge

Last 3rd at 1:19 p.m., an express bus passing Incheon Bridge fell off the bridge to kill 12 people.
An express bus which left Songdo to head for Yeongjongdo passed the tollgate of Incheon Bridge. Unfortunately, the bus failed to see a Matiz vehicle parked on the 2nd lane 300 meters ahead due to malfunctioning. The bus collided with the vehicle, hit the guard rail, and fell 10 meters down the bridge.
After hitting the guard rail, the bus was turned over 180 degrees, making its ceiling hit the ground first. This resulted in a terrible tragedy.

⇒ We need a device that can emit visual signs to clear the country's name of being the country with most traffic accidents, as well as to arouse people's attention to prevent accidents.

>> Drawbacks of Solar Raised pavement markers
  1. Easily damaged due to their structure and low-priced material.
  2. They are advertised as semi-permanent, but their actual lifespan is around 2~3 years, rendering it uneconomical.
    (Twice the money required for reinstallation)
  3. As time passes, light intensity is decreased, leading to dropped observability.
  4. Not quite functional for rainy nights or continuous rough weather.
  5. Price drop due to over-competition causes less performance. (Many made-in-China products)
