The solar street lamp is composed of solar cell module parts (including brackets), LED lamp caps, controllers, batteries and lamp posts. The lamp head part uses 1 W white LED matrix as the light source. In the solar power supply system, the performance of the battery directly affects the overall cost and service life of the system. The battery used by the company is a special colloidal battery for solar energy. Its service life is more than 3 times that of ordinary lead-acid maintenance-free batteries, up to 5- 8 years! It is beneficial to the reduction of system maintenance costs; the charge-discharge controller is equipped with light control, time control, overcharge protection, over-discharge protection, and reverse connection protection, achieving high cost performance.
The advantages of solar street light source:
1) High luminous efficiency, low power consumption, long service life, and low operating temperature.
2) Strong security and reliability.
3) Fast response, small unit volume, green and environmental protection.
4) At the same brightness, the power consumption is one-tenth that of incandescent lamps, one-third of fluorescent lamps, and the lifetime is 50 times that of incandescent lamps, and 20 times that of fluorescent lamps, after incandescent, fluorescent, and gas discharge lamps. The fourth generation of lighting products.
5) The advent of single high-power ultra-brightness LEDs has become possible in LED applications across the high-efficiency lighting source market, and will be one of the greatest inventions ever since Edison invented incandescent lamps. Solar street light working principle: Solar cell solar panels made by using the photovoltaic effect principle receive solar radiation energy and convert it into electrical energy output. After the charge and discharge controller is stored in the battery, the open circuit voltage of the solar panel is less than 4.5V at night. After the discharge controller detects this voltage value, the action discharges according to the controller setting mode. After the battery is discharged, the charge-discharge controller operates and the battery discharge ends. The main function of the charge and discharge controller is to protect the battery.

1, the characteristics of solar street lamps - one-way light, no light diffusion, ensuring light power.
2. The solar street lights have a common secondary optical plan, illuminating the solar street light to the desired lighting area, and further increasing the illumination power to reach the energy-saving intention.
3, LED light source power has reached 110-130lm/W, and there is still a lot of room for development, the theoretical value of 250lm/W. The high-pressure sodium lamp light power is added with the power to add, so the overall efficiency of solar street light is stronger than that of high-pressure sodium lamps; (This overall light efficiency is theoretical, high-power solar street lights are actually 250W above the pressure of high-pressure sodium lamp light Efficient than LED).
4, solar street light color rendering is much higher than the high pressure sodium lamp, high pressure sodium lamp color rendering index as long as 23 around, and solar street lighting color rendering index of 75 or more, from the perspective of visual considerations, to reach equal brightness, solar street light can evenly More than 20% lower than high-pressure sodium lamp, 5, solar street light decline is small, light decline of less than 3% a year, use 10 years still use the illuminance requirements of the road, and high pressure sodium light decay, a year has declined by 30% Above, as a result, solar street lamps can be used with lower power planning than high-pressure sodium lamps.
6, solar street lights have active control of energy-saving equipment, can now be satisfied with the same time not the same time the maximum possible drop in power requirements, save energy. Spark smart solar street light can realize computer dimming, time control, light control, temperature control, long-distance operation, active inspection and other humanized functions.
7, LED is a low-voltage device, driving a single LED voltage is a safe voltage, the single product LED power of the series is 1 watt, so it is a more secure than the use of high-voltage power supply, especially for public places (such as: street lamp Lighting, factory lighting, car lighting, civil lighting, etc.).
8, as long as the small size of each unit LED chip, so it can be prepared into a variety of shapes of the device, but also suitable for the volatile environment.
9, long life: can use more than 50,000 hours, to ensure the quality of three years. The downside is that the life of the power supply is not guaranteed.
10, high luminous efficiency: use ≥ 100LM chip, compared to traditional high-pressure sodium lamp can save more than 75%.
11, the device is simple: no need to bury the cable without a rectifier, etc., directly to the street lamp lamp device is connected to the lamp pole or the light source is nested in the original lamp shell. 12, excellent cooling control: summer temperature control below 45 degrees, and use passive cooling methods, summer heat to ensure inadequate.
13, reliable quality: circuit power supply full selection of high-quality components, each LED has its own over-current protection, no need to worry about damage.
14, uniform light color: without the lens, not to increase the brightness and consecrate uniform light color, and then ensure that the aperture color is uniform.
15. LEDs do not contain harmful metals, unlike high-pressure sodium lamps or metal halide lamps that cause damage to the environment when they are scrapped.
Summarizing the above principles, the energy-saving effect of high-power solar street lamps is significant, and replacing high-pressure sodium lamps can save more than 60% of electricity consumption. (waiting for research) Low protection cost: As compared with traditional street lamps, the cost of solar street lighting protection is extremely low. By comparison, it can be fully invested in less than 6 years.
