How to measure the performance of a solar road stud

How to measure the performance of a solar road stud
1. Pressure resistance
If a road studs cannot withstand a certain amount of pressure, it will easily shatter after being run over or impacted by a car, so naturally it will not work properly, so pressure resistance is a basic condition for a solar spike to work properly. But the problem is that the solar nail itself is an electronic product, including the electronic part, want to make the electronic part also has a high degree of pressure resistance is not an easy thing, so in general the solar nail pressure resistance than ordinary nail poor performance.

2. Sealing performance
If the solar nails are not completely sealed, it is natural that water will seep through, water seepage will cause a short circuit, the consequences are disastrous, so a qualified solar nail sealing performance must also pass.
3. Brightness
Solar nails active luminous, clear outline of the road; compared to reflective nails, its very important a feature is the luminous intensity.
4. Stability
Battery life: An important factor in determining the life of solar road studs is the life of the battery, the choice of battery is crucial. There are currently two types of batteries on the market for reference, one is charged and discharged 500 times after the battery capacity reduced to 50%; the other is charged and discharged 1000 times after the battery capacity reduced to 79%.
The battery life must not only be long enough, but it must also be able to operate properly over a wide temperature range. Batteries are chemical substances inside, if the temperature is too high or too low, the battery will not work, the solar road studs battery operating temperature range must meet the requirements of the actual use of the environment.

Electronic circuitry: the design of the circuit board must follow the principle of simple and effective design, do not artificially complicate, because one more line is one more possibility of failure. The electronic components must also be carefully selected, as any problem with one of them can bring the whole system to a standstill.
Soldering: Soldering must be secure, because LED solar road stud are subjected to daily vehicle crushing and impact, and the slightest loosening of the solder joints can cause the wiring to come loose and fall off. Therefore, when choosing a soldering gun and solder, you must select high-quality products to ensure that the solder joints are solid and reliable, and can work for a long time in a relatively "harsh" environment.
Solar panels: solar panels directly absorb solar energy and convert light energy into electricity, so to speak, is the first link in the solar nail the entire work system; its efficiency directly determines the efficiency of the solar nail work efficiency. Now commonly used is monocrystalline silicon solar panels, this is because of the high photoelectric conversion rate of monocrystalline silicon solar panels, about 14%, to maximize the conversion of solar energy into electricity, to ensure that the solar nails work when the energy supply. In addition, solar panels must be highly rigid, wear-resistant boards. Solar panels are subjected to daily wear and tear by wheels, and if they are not strong enough, they will easily wear out and thus affect the conversion efficiency of the solar panels.
5. Cell matching performance
After 8 hours under standard test conditions, the rated capacity of the battery should meet the needs of the road studs for 72 hours of normal light; even when the sunlight level is less than 1000LX, the rated capacity of the battery should meet the needs of the road studs for 12 hours of normal light after 8 hours of charging. Special attention must be paid to this point as well. If the batteries are not well matched, they will not be able to shine in rainy weather due to insufficient stored power. This makes the  road stud light useless and they cannot be used at all. This is where the limitations of capacitive solar road studs come into play. In the standard test conditions placed under 8 hours, the capacitor's rated capacity can only meet the needs of the nail normal light 12-14 hours, so that the capacitive solar nail on the actual use of the environment is very demanding, not only the sunlight should be strong enough, and can not have continuous cloudy weather, otherwise it is difficult to work properly.
6. Environmental adaptability
solar-powered road studs are used in a complex and changing environment, the temperature and humidity may be very different. Some areas of the year-round temperature is very low, and some areas of the year-round temperature is very high, and some day and night temperature difference is particularly large, the climate is wet, dry climate, these will affect the solar nails work properly, so the design of solar nails should take full account of environmental adaptability.
The environmental performance of solar road studs is a comprehensive test of their mechanical and electrical properties, involving structural design, circuit design, electronic device performance and many other aspects, including their production process. This requires all aspects of the work to be done in order to ensure that the solar road studs have good environmental performance.
