How to identify the quality of solar street light sources
One: Look at the brightness of the lamps.
The power determines the brightness. Generally, the brightness of the higher power LED lamp will be much brighter than the lower power LED lamp, and the price will be relatively higher.
Two: Look at the antistatic ability of the lamps.
The LED light source with strong antistatic ability has a relatively long life. Generally, LED lights with antistatic power greater than 700V can be used as LED lighting.
Three: Understand the colloid of lamps and lanterns.
The colloid of ordinary LED lights generally uses epoxy resin, and high-quality LED light sources generally have anti-ultraviolet and fire-retardant functions. Because the lighting with anti-ultraviolet and fire-retardant is relatively expensive, high-quality outdoor LED lighting is relatively expensive. less.
Four: Understand the power supply of lamps and lanterns.
Generally, the lamp is broken because the power supply is burned out, so the power supply plays a vital role in the life of the entire LED lamp. Manufacturers will design different power supplies according to different design requirements, which are mainly divided into constant current power supplies and constant voltage power supplies.
Five: Understand the radiator of the lamp.
The appearance of the luminaire can determine the effect of the radiator. If the external or internal of the luminaire is made of aluminum, it will have a good check and balance effect on the thermal effect of the luminaire, because the temperature determines the service life of the LED lamp bead, and solving the thermal effect can effectively Extend the service life of LED lamps.
Six: Understand the leakage current of the lamps.
The LED is a unidirectional conductive light-emitting body, and a reverse current can be judged as leakage. If the leakage is serious, the life of the LED lamp will be reduced and the price will be relatively cheaper. LED lights mainly rely on chips to emit light, and different chips have different prices. If you want to choose better quality chips, you can choose imported products.
Seven: Look at the light-emitting angle of the lamps.
LEDs with different purposes have different light-emitting angles. The common light-emitting angles on the market are 8°, 15°, 25°, 45°, 60°, 90°, 120°. According to the angle, it can be divided into narrow beam, medium beam and wide beam. If you want to achieve For better luminous efficiency, narrow-angle beams should be used, but according to different needs, you should choose a lamp that suits you.
Eighth: Know the wavelength of the lamps.
The wavelength of the lamp determines the color of the light. The quality of the products produced by the well-known and qualified manufacturers are generally higher. Generally, they use the spectrophotometer to produce the LED lights with relatively pure colors, but do not use the spectrophotometer for production. The output LEDs will have inconsistent wavelengths, and the colors will naturally be inconsistent.
Nine: Know the size of the chip.
Taking the side length as the unit of measurement, the quality of the large chip LED lamp is better than that of the small chip, and the price is naturally more expensive.
The quality of the solar street light source directly affects whether the solar street light can work normally. I hope that when choosing solar street lights, you can learn to distinguish the quality of the solar street light source, don't be deceived by black-hearted businesses, and remember to consume rationally.

How do solar street lights save energy
2021-12-02
1. Energy saving and environmental protection
Solar street lights are mainly composed of four sectors: photovoltaic modules, light-emitting diodes, solar cells and controllers. Photovoltaic modules absorb light during the day, convert solar energy into electrical energy, store it in solar cells, and discharge and illuminate at night when it gets dark.
In general, when the weather is fine, it only takes 4 hours to fully charge under strong light. After each charge is completed, it can be guaranteed for more than 5 days, and it can work normally if it lasts for 3 days in rainy or cloudy weather.
In short, in cities with increasing energy consumption, urban electricity consumption has become too important: industrial electricity and household electricity consumption have remained high in recent years and have been increasing year by year. Is common. If solar street lights can be widely used, it will greatly reduce the electrical power of the city.
2. Energy-saving economy
First of all, each solar street lamp is a relatively independent system. There is no need to embed cables or excavate the road during installation and construction, which saves a considerable part of manpower, material resources and installation costs; besides, it consumes electricity, and an ordinary street lamp lights up all day. The lamp time is about 6 hours, the power consumption is about 2 degrees, and the electricity bill is more than 300 yuan a year. If an urban area is calculated based on 300 street lights, it costs nearly 100,000 yuan a year. Solar street lights can be saved.
According to reports, 50 million new outdoor lights are added every year across the country. If solar lights can account for one-thousandth, it can save the country hundreds of millions of kilowatt-hours of electricity a year.

What is the reason why solar street lights turn on and off
mainly has the following 4 reasons:
1. Poor contact of the connector
Mainly check the joints of various places of solar street lights, especially the joints of led lamp head, controller and battery. Whether there is looseness, poor contact or oxidation, it will cause the situation of turning on and off during use.
2, controller problem
The controller is the core component of the solar street light. Its quality determines whether the solar street light can work normally. To check whether the controller is damaged, you can check the three indicator lights of the controller. Under normal conditions of the controller, only green or red lights will be displayed. If the yellow light appears, it means that the controller has failed. At this time, you need to contact the manufacturer for repair or replacement.
3, the line is faulty
If the line is damaged, this situation will also occur. Generally, the damage of the line usually occurs at the corner or in the place that is easily exposed.
4, led failure
Solar street lights use LED lamp beads as the light source. LEDs are solid light sources and have a much longer service life than traditional tungsten wires. In addition to quality problems, there is another possibility that the fixed solder joints are loose.
Generally speaking, the solar street lights may be on and off when there is a problem with the controller. At this time, contact the manufacturer in time to ensure that the solar street lights can be used normally.
