Introduction of led street lamp procurement

A, solar led street lamp procurement instructions

1, pay attention to the overall configuration of the system.

When purchasing solar led street lamps, we should not only pay attention to the quality of lamps, but also pay attention to the overall configuration. Including the peak wattage of photovoltaic module, the capacity of lithium battery and the stability of led street lamp. Only when all the problems are taken into account can the practical performance of solar led street lamps be guaranteed to be higher.

2. Pay attention to the quality of components

Solar led street lamp consists of lithium battery and controller. The quality of components will directly affect the quality of lighting. In particular, the capacity of lithium batteries is the key to determine the lighting time of street lamps. Therefore, when choosing solar led street lamps, we must choose the ones with good component quality and large lithium battery capacity.

3. Pay attention to chip quality

The chip can be said to be the core part of the solar led street lamp. If you choose chips with poor quality, it will directly affect the performance of street lamps. Some unscrupulous merchants will choose low-quality chips in order to win more profits. If they buy such products, their future use will be seriously affected.

4, pay attention to the configuration of virtual standard.

The practical performance of solar led street lamps is very strong, and the competition pressure between brands is great, which also gives many unscrupulous businesses an opportunity. Marking false information on street lamp products, including wattage of light source, battery capacity, materials used in lamp post, etc. Be sure to check clearly before buying.

5. Pay attention to heat dissipation.

Because the solar led street lamp has been in a harsh environment for a long time, the requirements for its heat dissipation performance are more stringent. If there is no good heat dissipation scheme, after a period of use, it is prone to rapid aging and poor stability, which is one of the reasons why many products can not reach the expected value.

6, pay attention to the copper wire as a gold wire.

As we all know, the price of gold wire is very expensive, so many solar led street lamps on the market are replaced by copper alloy or gold-plated silver alloy wire. Although these materials are better than gold wire in some aspects, their performance will be much worse after actual use.
