1. Active guiderails are a type of rail marker placed along both sides of the road. They are used during nighttime or in foggy weather to indicate road and tunnel edges. Composed of a housing, LED, wires, and control components, they can be powered by solar panels or AC power. They can function solely through active illumination or in combination with passive reflection, serving as visual guidance facilities. Operation is typically constant light or blinking. For tunnel use, active guiderails must be resistant to oil stains, require multiple LEDs, and the housing can be made of plastic. For road use, the housing of active guiderails must withstand compression, often made of cast aluminum, with a combination of active illumination and reflection.
2. The active spikes operate in a steady or synchronized blinking mode, connected via wiring, with replaceable batteries and circuits, offering greater pressure resistance, enhanced stability, and extended lifespan.
3. Traditional solar road studs operate as a standalone system, independently handling photovoltaic conversion, electrical energy storage, and LED flashing. They contain solar panels, circuits, and batteries, but the compressive strength is difficult to achieve at high levels, and the batteries are not replaceable, affecting the lifespan of the studs. Active road studs feature the concentration of solar panels, batteries, and control circuits within each stud into a single control box. One control system can effectively manage a distance of up to 500 meters. The solar road studs retain only the LED and a simple voltage stabilization circuit for display purposes, reducing internal circuitry. This allows for a compressive strength of up to 16 tons. Traditional solar road studs require ample sunlight at each stud point. Active road studs, however, only need one solar panel placed in a sunny area, making them suitable for installation on winding mountain roads with dense forests and insufficient sunlight on the ground. They play an irreplaceable role in the application of tunnels and mountain roads.
