Do you know what are the common problems with Solar Road Studs?

After the Solar Road Studs produced by many manufacturers are installed on the road, such problems often occur, which are mainly reflected as follows:
Hollow structure In many places, the Solar Road Studs installed on the road are often crushed or the upper and lower structures are separated, which is actually the reason why the structure of the Solar Road Studs is unreasonable. Many people think that aluminum shells are more resistant to pressure, and this understanding is also one-sided. As long as the interior is hollow, generally speaking, the whole will not be oppressed.

Solar Road Studs with peg feet, this route stud is divided into two parts, the lower part is the base with peg feet, the upper part is the solar panel, LED and lampshade, the upper and lower parts are connected with a few screws, now Solar Road Studs with peg feet Most use this structure. The product is installed on the road, and when glued, it actually just fixes and glues the lower half of the Solar Road Studs, and the upper half is just fastened to the lower half with a few small screws. This structure is most prone to quality problems, that is, the separation of the upper and lower parts. During the rolling process of the vehicle, several small screws were too thin and the force was too small. The vehicle was rolled several times and the top flew away.

The first countries to use Solar Studs as active lighting and passive lighting are Japan and South Korea. These countries have very high requirements for traffic safety facilities and products. For some reason the Solar Studs don't work properly, also supplemented with the Road Studs reflected light. Europe is considering and formulating relevant standards for Road Studs products, in which reflection performance is one of its important indicators.

The Solar Studs produced by some manufacturers in my country, some reflectors reflect, and some do not reflect. Standard reflector cores are electroformed with needle-type electroformed plates with very high precision. In addition, after the motherboard is used for many times, in order to ensure the reflectivity of the reflection mold core, it needs to be removed and reground. This kind of pin-type motherboard can only be produced by a few companies in the world. Some small electroforming factories in China have not yet been able to cast pin-type motherboards. The reflector products they produce look like reflections, but they do not actually reflect .
To sum up, I think compression resistance, high temperature resistance and reflection should be the three most important indicators of protruding Solar Studs, and the three are essential.
