Solar energy lamps and lanterns is related to what price

- -

is our solar street lamps are seen in everyday life, there are a lot of solar lamps and lanterns is popular, but decided to solar lamps and lanterns is what is the cause of the price? Let's look at it. A

solar energy lamp, lamp shell shell choice, don't look down upon the lamp shell, if think lamp shell is not important, it would be wrong, in fact, is the key to protect the wick lamp shell, if the lamp shell is very strong so the service life of the solar lamps and lanterns also will be a lot of for a long time, the lamp shell can be subdivided into ordinary lamps shell and die-casting die whole shell this two categories, the former heat dissipation performance is slightly worse, more suitable for small power light source, which heat dissipation performance is better, is suitable for the power of the light source.

2, chip chip is the key to direct can decide the LED brightness, droop, efficiency and power are also important data and its related solar energy lamps and lanterns, is to determine the important aspect of its price, and the chip quality mixed above the market now, so it's best to start testing the chip compared to buy later.

3, constant current source

also is to make the circuit can stable power supply of constant current devices, because solar lamps and lanterns is a need to loop current is constant, so add the price of constant current source will be a little bit more expensive.

the influencing factors of solar lamps and lanterns price probably have these, so need to pay more attention to these aspects when buy, to choose and to the right.
