Although solar LED road stud is a relatively complete traffic safety facilities, but there are some problems. The first problem of solar LED road stud is: the compression value is not enough. We have carried on the experiment and the reason analysis for the insufficient compression value of the solar LED road stud.

The road mounted solar LED road stud products have problems in compression, which will cause the solar LED road stud products to be crushed. This is actually caused by the unreasonable structure of solar LED road stud. The main performance of the unreasonable structure of solar LED road stud is: the interior of solar LED road stud is hollow structure.
We should not think that the aluminum shell solar LED road stud is more pressure resistant. In fact, the solar panels of these solar LED road stud products are hollow and not pressure resistant at all.

When we do the compression test of the solar LED road stud in the laboratory, when the pressure is 8.1 tons and 8.9 tons, the solar LED road stud breaks. Such a solar LED road stud is not even as compression as the qualified plastic LED road stud. The compression value of the qualified plastic LED road stud is 16 tons. Of course, this kind of structure can not meet the requirement of the Ministry of communications for 10 tons of compression. General pressure detection equipment can do solar LED road stud.
The harm of hollow inside the solar LED road stud is also shown in the LED lampshade. LED lampshade will be damaged because it is hollow, and then LED itself will be damaged. How to detect this? We have made an impact instrument for solar LED road stud lampshade, and the detection method is as follows: after the white board is drawn out, the steel ball falls freely at a height of one meter, and vertically impacts the LED lampshade of solar LED road stud to see if the lampshade is broken.
