Solar road stud is a kind of road stud installed along the road surface. Solar road studs are composed of reflective materials, shells, solar panels, LEDs, and control devices, which play an important role in outlining the shape of the road, indicating the direction of the road, at night or in rainy and foggy weather, and in driving. The corner of the road induces the driver's sight and eliminates potential safety hazards. This article will discuss several aspects of measuring the performance of solar road studs.
Ability to withstand stress
If the solar road stud cannot bear a certain pressure, it is easy to be crushed by the vehicle and cannot work. Therefore, compression resistance is the main quality of solar road studs. Solar road studs are originally electronic products and contain electronic components. It is not easy to make electronic components have a high degree of pressure resistance. Generally speaking, the compressive strength performance of solar road studs is not as good as that of ordinary types.
Sealing performance
If the solar road studs are not well sealed, water may seep in and cause a short circuit with serious consequences. Therefore, a qualified solar road stud must have good sealing performance.
brightness
Solar road studs actively emit light to clearly outline the outline of the road; compared with ordinary reflective road studs, the high luminous intensity is very important. The Ministry of Transport's requirement in this regard is 200 MCD.
Battery Life
The usage time of the battery in the solar road stud is an important factor in determining the service life of the road stud, so it is very important to use a battery that has both a long span and can work in a wide temperature range.
circuit
The design of the circuit should follow the simple and effective principle. unnecessary
Complexity should be avoided because one more circuit means one more chance for failure. Also, extra care needs to be taken when selecting electronic components, as damage to a single component can bring down the entire system.
welding
Ensuring that the studs are welded securely is critical. Since the road studs are subjected to the rolling and impact of countless vehicles, loose welding seams will inevitably cause the lines to fall off. A good quality torch and solder must be selected when installing studs to ensure that the studs are welded securely and prepared for harsh working conditions.
Solar panels
Solar panels directly absorb solar energy and convert light energy into electrical energy, which is the first link in the entire working system of solar road studs; it directly determines the efficiency of solar road studs. Solar panels must have high hardness and wear resistance. Solar panels have to bear the wear and tear of the wheels every day. If the strength is not enough, it is easy to wear and tear, which will affect the conversion efficiency of solar panels. Solar panels are prone to wear and tear, so not having enough capacity will hurt conversion efficiency as it will be run over by quite a few cars.
