How to judge the advantages and disadvantages of solar street light sources?

1. Look at the brightness of the lamp
Generally speaking, the brightness of high-power LEDs will be much brighter than low-power LEDs, and the price will be much more expensive.

2. Look at the anti-static ability of the lamp
Led has strong anti-static ability and long service life. Generally speaking, LEDs with anti-static voltage greater than 700V can be used for LED lighting.

3. Understand the leakage current of the lamp
LED is a unidirectional conductive light-emitting body. If there is a reverse current, it is called leakage. Leds with large leakage current have a short service life and a relatively low price.

4. Chips used to identify LED lamps
The light-emitting body of LED chips. Different chips are usually of good quality and expensive. Chips are imported from abroad.

5. Look at the luminous angle of the lamp
LEDs for different purposes have different luminous angles. According to different needs, it is very important to choose the application suitable for purchasing lamps. So you should know the website you are shopping on.

6. Understand the wavelength of the lamp
LEDs with the same wavelength have the same color and are relatively expensive. We should realize that without LED beam splitting
It is difficult for color separation machine manufacturers to produce pure color products, so it is necessary to choose products produced by reputable manufacturers.

7. Understand the colloid of the lamp
Ordinary LED colloid is usually epoxy resin. Anti-ultraviolet and fire retardant LED is expensive. High-quality outdoor LED lighting should be protected from ultraviolet and fire.

8. Understand the lamp radiator
The radiator can see the appearance of the lamp. If the exterior or interior of the lamp is made of aluminum, the thermal effect of the lamp can be solved, so as to better extend the service life of the lamp, and the temperature plays a key role in the service life of the LED lamp beads.

The working principle of solar street lights

1. System composition
The solar street light system consists of photovoltaic solar panels, solar street light lamp heads. Intelligent controller (lighting controller). Timer and controller)

2. Working principle
The working principle of solar street lights is to illuminate the photovoltaic solar panels during the day to achieve the photovoltaic effect, convert light energy into electrical energy, and store the current in the solar battery through the charge and discharge controller. When the lighting gradually decreases at night, the open circuit voltage of the solar panel will also decrease. When the charge and discharge solar controller detects that it is lower than the set voltage value, the battery will discharge the lamp head to emit light. After the battery discharge time reaches the controller setting value, the charge and discharge controller moves and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery and make it work for a long time!
