Road studs are a common type of traffic infrastructure used to mark road edges and lanes. There are two common types of road studs: one is passive road studs, such as reflective road studs, which do not require external energy; the other is active road studs, which require power supply, including solar road studs, battery-powered road studs, wired power supply road studs, etc. Next, let’s take a look at where the energy of these road studs comes from.

Passive road studs

Passive road studs mainly refer to reflective road studs, which are road safety facilities that do not require external power or battery power. They mainly rely on the reflection principle of natural light and vehicle lights to provide road instructions and safety warnings. Passive road studs usually use high-efficiency reflective materials such as microprisms, glass beads, or others

. When the headlights of a vehicle shine on the reflective road studs, the reflective materials will reflect the incident light back in the direction of the driver. This reflection can provide clear road instructions to the driver at night or in low visibility.

Active road studs

Active road studs include many types. Here is a brief introduction for you.：

1. Solar power supply

Solar road studs are one of the most common ways to power road studs. It uses photovoltaic panels to absorb solar energy, converts light energy into electrical energy during the day and stores it in built-in batteries, and emits light through LED lights at night or in low visibility conditions (such as foggy days). The characteristics of solar powered road studs are environmental protection, economy, no need for external power supply, easy installation, and low maintenance cost. Solar led road studs are suitable for scenes such as highways, tunnels, and parking lots. However, since the energy source depends on sunlight, if there is continuous rainy weather, the energy supply is insufficient, which may affect the battery life.

2. Battery power supply

Battery-powered road studs provide power through built-in batteries, usually rechargeable batteries or disposable batteries. This method is mainly used for temporary or specific area road studs, such as temporary signs in construction areas. Battery-powered road studs can support the operation of LED lights, but they need to be replaced or charged regularly, and the maintenance cost is relatively high.

3. Wired power supply

Wired-powered road studs provide continuous power through underground cables. This type of road stud is usually installed on important sections or roads that are used for a long time, which can ensure the long-term stable operation of the road studs. Especially in areas where lights are required for 24 hours continuously (such as airport runways and highway tunnels), wired power supply is often used. The biggest advantage of wired-powered road studs is stability, but cables need to be laid, the installation cost is too high, and maintenance is also difficult.

In addition to the above three common power supply methods, active road studs also have electromagnetic induction power supply, wireless power supply, and other methods, but due to technical difficulties and other reasons, they have not been applied to optical amplifiers.

Through the above introduction, we know that there are two main types of road studs currently in common use: one is reflective road studs, and the other is solar led road studs. Both types of road studs have the advantages of easy installation and simple maintenance. Especially solar powered road studs are widely used in energy-saving and environmentally friendly application scenarios. Solar road studs have obvious advantages at night or in some areas with complex roads. The bright and flashing light it emits plays a role in strengthening reminders and provides a stronger guarantee for road safety.
