Measure The Performance Of A Solar Spike From The Following Aspects:
Jan 08, 2015

Compression resistance

If the solar spike can not withstand a certain pressure, it is easy to break off after the car is rolled or impacted, and naturally cannot work normally. Therefore, the compression resistance is a basic condition for the normal work of the solar spike. However, the problem is that the solar stud is an electronic product, which contains electronic parts. It is indeed not an easy task to make the electronic part also have a relatively high degree of compressive performance. Therefore, in general, the compression resistance of solar studs is better than Ordinary spike is worse. The technical requirements of the Ministry of Communications up to 2014 are 10 tons.

There are several ways to effectively improve the compressive performance of solar spikes: First, the exposed solar panels use PC ballistic materials to enhance the compressive capability of the electronic part; second, IC control is used as much as possible to reduce electronic circuits. The volume to reduce the pressure on the electronic part; Third, design some stiffeners on the shell to share the pressure on the electronic part.

Sealing performance

If the solar energy spikes are not completely sealed, they will naturally seep through. Water seepage will cause short circuits and the consequences will be catastrophic. Therefore, a qualified solar stud sealing performance must pass.

There are several ways to improve the sealing performance of solar studs:

(1) Separate design. The LED lampshade and the internal circuit board are isolated, and even if the LED lampshade is broken, the interior of the solar energy spike is still guaranteed not to seep.

(2) Use a strong neutral adhesive material to ensure that the solar panel, LED lampshade and spike shell are tightly bonded with no gap in the middle.


Solar spikes actively emit light and clearly outline the road. Compared with the reflective spikes one of the most important features is the luminous intensity. This indicator requires 2000 MCDs.


Battery Life An important factor in determining the life of a solar spike is the battery life. The choice of battery is critical. There are two types of batteries available on the market in 2014. One is after charging and discharging 500 times, the battery capacity is reduced to 50%; the other is after charging and discharging 1000 times, the battery capacity is reduced to 79%. [2] 

The battery life should not only be long enough, but it must be able to work in a relatively large temperature range. The inside of the battery is a chemical substance. If the temperature is too high or too low, the battery cannot work. The battery operating temperature range of the solar spike must meet the requirements of the actual use environment. The requirements of the National Transportation Ministry are -10 degrees to 50 degrees, and the actual environment will often exceed this range, which puts higher requirements on the batteries.

Electronic circuit board design must follow simple and effective design principles, not artificially complicated, because one more line is more likely to fail. Electronic components must also be rigorously selected because problems with any one electronic component can make the entire system paralyzed.

Weld welding must be reliable, because the solar energy spikes withstand the rolling and impact of the vehicle every day. A little loose of the solder joint will cause the line to loosen and fall off. Therefore, when selecting welding torches and solders, we must select high-quality products to ensure that the solder joints are solid and reliable, and that they can work in relatively “bad” environments for a long time.

Solar panels Solar panels directly absorb solar energy and convert light energy into electrical energy. It can be said that the solar link is the first link in the entire work system; its work efficiency directly determines the working efficiency of solar studs. The single-crystal silicon solar panels have been widely used since 2014. This is because single-crystal silicon solar panels have a high photoelectric conversion rate of about 14%, and they can convert solar energy into electrical energy to the maximum extent possible to ensure that solar energy spikes work. Energy supply. In addition, solar panels must be high-hardness, wear-resistant circuit boards. Solar panels are subject to rolling abrasion of the wheels every day. If the strength is not enough, it is easy to grind the flowers, which will affect the conversion efficiency of solar panels.

Battery matching performance

8 hours under standard test conditions, the rated capacity of the battery should meet the requirement of 72 hours of normal lighting of the spike; even if the sunlight is less than 1000LX, the rated capacity of the battery should meet the normal light emission of the spike for 12 hours after the battery is charged for 8 hours. Needs. This must also pay special attention. If the matching performance of the battery is not good, there will be a shortage of stored energy of the battery in rainy weather, which will cause the solar pin to fail to emit light. As a result, solar spikes have no practical value and cannot be used at all. This is where the limitations of capacitive solar spikes are. When placed under standard test conditions for 8 hours, the rated capacity of the capacitor can only meet the need for normal lighting of the spikes for 12-14 hours. Therefore, the requirements of the capacitive solar studs for the actual use of the environment are very harsh, and not only the sunlight should be sufficient. Strong, and can not have continuous rainy weather, otherwise it will be difficult to work properly.

Environmental  adaptability

The use environment of solar spikes is complex and varied, and the temperature and humidity may be quite different. The temperature in the northern winter is very low, the temperature in the south is very high in summer, the temperature difference between day and night in the northwest is particularly large, the southeast is humid, and the northwest is dry. All these affect the normal operation of the solar spikes. Therefore, the design of solar spikes should fully consider the environmental adaptability. .

The temperature requirements of the Ministry of Communications up to 2014 were in the range of -20°C to 85°C, and three cycles of tests were conducted between 20°C and 60°C to see if they could adapt to the requirements of the environment. The requirements of the Department of Transportation on the thermal and hygrothermal performance of solar spikes are that after 48 hours of testing at 45°C and 98% relative humidity, they can still work properly.

The environmental adaptability of solar spikes is a comprehensive inspection of their mechanical and electrical properties, involving structural design, circuit design, and electronic device performance, and even their production processes. This also requires that all aspects of the work must be done in order to ensure that the solar spike has a better environmental adaptability.
