C26 Pixel Tube
Introduction to the C26 Pixel Tube:
The C26 Pixel Tube is a wired, series-connected LED guidance point light for tunnels. Commonly referred to in the industry as a “tunnel pixel light” or “tunnel contour marker pixel tube,” it is a specialized lighting fixture designed for guiding traffic flow in highway tunnels and underpasses; The model designation “C26” generally refers to a compact size with an outer diameter of 26 mm. These lights are powered by low-voltage DC and feature multiple LEDs wired in series. Installed on both sides of the tunnel walls, they use a controller to produce dynamic lighting effects such as constant illumination, scrolling patterns, and strobe effects. These effects outline the edges of the lanes, enhancing visibility for drivers in the dimly lit tunnel environment and reducing the accident rate within the tunnel.
Features of the C26 Pixel Tube:
1. Equipped with Epistar LED chips from Taiwan, it offers strong light penetration over long distances, minimal light decay, and stable brightness. It provides clear visibility up to 600 meters away in low-light tunnel environments, and its dynamic, flowing light effects are highly effective in guiding and alerting drivers.
2. The fully encapsulated, sealed design meets an IP65 protection rating or higher, resisting penetration by tunnel condensation, fog, and rain. It remains watertight and short-circuit-free even in long-term, humid, enclosed environments.
3. Modular design ensures low maintenance costs. A single failure does not affect the operation of the entire circuit; damaged modules can be replaced individually without dismantling the entire section of wiring.
4. The C26 has a diameter of only 26 mm and a slim profile. It is installed flush against the tunnel wall, so it does not intrude into the clearance for vehicles and will not be scraped by large vehicles. It requires no extensive trenching during tunnel civil engineering modifications, making installation convenient.
