LED solar street lights can output different power through pulse width adjustment

>

During this period of time, it is the off-season of the market itself, and all projects require a lot of bidding. For our led solar street light manufacturers, there is no difference between the off-season and the peak season. We are always busy all year, because we do What matters is quality, what matters is after-sale, and what matters is credibility, but those small workshops are more difficult to survive. In order to receive orders in the off-season, they also make great efforts. They can only have a little competition by constantly lowering prices. Advantages, but the cost is transparent, how can they meet the requirements?

The solar street light controller is an important condition for the service life of the solar street light. If the led solar street light control is well selected, then the led solar street light can truly be controlled by no one. First of all, we will discuss the problem of the controller. The controller has a very low cost ratio in the entire led solar street light price light system. Although it looks like an inconspicuous small object, it plays a very important role. If it is good, the stability and service life of the entire system will be greatly reduced, and a relatively mature controller can also reduce the cost of the entire system through functions and achieve the purpose of saving costs.

Among the lamps used in solar energy applications, led solar street lamps are suitable for outputting different powers through pulse width adjustment. While limiting the pulse width or limiting the current, the duty cycle of the entire output of the LED light is adjusted. For example, a single 1W LED7 string of 5 and a total of 35W LED lights can be discharged at night, and the power can be divided into late night and early morning hours. Adjustment, such as adjusting to 15W in the middle of the night, adjusting to 25W in the early morning, and locking the current, so that it can meet the lighting all night, and save the configuration cost of battery panels and batteries. Long-term tests have proved that the LED lamp with pulse width adjustment method generates much less heat and can prolong the service life of the LED.

Now everyone knows the price of led solar street lights. Most of them use lithium batteries first, which provides them with a good foundation for cutting corners. Everyone knows the system voltage of led solar street lights, which is normally 12V, and lithium battery led In order to be used with solar street lights, the lithium battery also needs to be made into 12V, but the single voltage of the lithium battery is 3.7V, which is 3 times that. For the same 30AH lithium battery, the difference between 12V and 3,7V will be 3 times the price. This also gives them the opportunity to cut corners.

Compared with the knowledgeable people, they will definitely understand that under the same conditions as the LED solar street light, the voltage becomes smaller and the current becomes larger, so the responsible thing will be easily burned out. The main problem is that the 3.7V street light will have 12V solar energy. Are the street lights on? The current is 3 times larger, and the service life is shortened by 3 times. You may think it is a good deal in front of you, and it is a lot cheaper, but it will be very troublesome in the later stage. That's the end of your engineering career. Would you be willing to gamble on this tiny profit?
