Best Solar Street Lighting Light Source

August 14, 2023

Solar energy is a sort of sustainable and clean energy that is currently popular and widely used in our daily life. Solar street lights, solar water heaters, and other related devices are examples of common solar commodities. Outdoor solar street lights are not only easier to install and have a longer lifespan than standard street lamps, but they also have a considerably higher power source efficacy. They are also environmentally friendly and energy efficient. It has the potential to significantly reduce the government's annual energy costs. In conclusion, solar street lights are gradually replacing traditional street lights in many regions since they can meet people's needs in every aspect. The most important component of external photovoltaic street lighting is the illumination source.Typical lighting fixtures include high-pressure sodium lights, energy-efficient lamps, induction lamps, and LED light sources.



The electrical ballast gets a DC 24V (12V) input from the high-pressure sodium lighting and outputs a low (or high) frequency to the lightbulb. When an electrical battery is utilized, the lifespan of the bulb can be increased by more than 30%, which is quite beneficial. Energy-saving lights are bright and efficient while consuming little electricity. The low-voltage bulb tube has a service life of around 2000 hours before becoming dark, making it ideal for solar yard lights and solar grass lights. The induction light is both bright and efficient, and it consumes very little electricity. In terms of illumination efficacy, these lights can attain more than 80lm/w, which is comparable. In terms of utility life, the LED light source has the longest lifespan of all of these public lamps. The LED light source emits the least amount of pollution and contains no dangerous elements or UV radiation. Combining low-voltage LED power sources with solar power supplies is straightforward. Other light types require a greater increasing range, have substantial power transfer losses, and emit a lot of electromagnetic radiation. LED lights are the most expensive, while gas lights are the least expensive. Because the LED light source is the best of these options, we frequently recommend it to clients.



After selecting LED for the outdoor photovoltaic street lights, how should we choose the LED light source that best meets our illumination requirements?



We must first determine the LED light source's power supply. There are commonly two types of power supplies used for outside solar street lights: constant voltage power supplies and constant current power supplies. A continuous current power source's output DC voltage varies when the load impedance changes, whereas the current remains constant. When using a street light, the maximum power and amperage that it can sustain must be considered. Because the voltage is constant, sufficient impedance should be provided when using a continuous voltage power supply.



Second, we must determine the brightness of the street lamp. The position of street lamps, the height of lighting poles, and the strength of the photovoltaic street light source are all distinct features. Because a taller street light has a wider brightness range and less visible illuminance than a lower street light. As a result, while selecting a light source, the height of the public lamp must be considered. The public lamp's strength is not as great as it could be as long as it can meet the demand for illumination. Higher battery and solar cell performance standards are also required for high-power illumination sources. Because a solar street light is an illumination system made up of many different accessories, the numerous accessories that comprise it must be adjusted to one another. A 20W LED light source is normally recommended for light poles of 3-4 meters, and a 30-50W light source is recommended for poles of 5-7 meters. If you're not sure about the brightness of different power light sources, you can buy a sample to test. LED solar street lights have an output power range of 30 to 60 watts, which is sufficient to power most lighting systems.



Obviously, concentrating just on strength is insufficient. Another critical component is the flow of light. It specifically refers to the total volume of visible light emitted by the light source each second. The better the light flow in a limited space, the brighter the world looks to our eyes. Depending on the circumstances, a light source with a lower wattage within the same bright emission range can be chosen, which is more energy-efficient and environmentally friendly.



Fourth, determine the color tone of the all-encompassing integrated photovoltaic street light source. When choosing a photovoltaic LED street light, the hue tone should be considered. Public light bulb carriers are classified into three types based on color temperature: white light, normal light, and mild light. Different groups have different lighting effects and create different emotions in people. Weather conditions and photovoltaic street light supply must be coordinated. First and foremost, it must be able to make people observe the situation of the roadways clearly without making them feel blinding or dull. This is more important. Driving fatigue is easy to develop if the external solar street lamp's head is difficult to see. White or bright white light up to 3000K is ideal for public illumination.
