Solar led street lamp, a perfect combination of solar energy and led light source. As the name suggests, the solar led street lamp is used to provide outdoor illumination through solar energy. Why do we say it a great combination of solar energy and leds. Let's go on with this paper.

In today's world, major energy sources such as oil, coal, and natural gas are facing the danger of resource depletion. Simultaneously, the pressure on environmental protection is also increasing. Therefore, environmental protection and energy conservation have become the goals pursued by all walks of life worldwide. Solar energy is a clean and green energy source, and semiconductor light-emitting diodes (LEDs) are also environmentally friendly, energy-saving, and highly efficient solid-state electric light source. The combination of the two has promoted the further development of solar power street light technology, and the lighting problems in more places have been solved.

1. Solar energy

Solar energy is the most important basic energy source. Biomass energy, wind energy, tidal energy, water energy, etc. all come from solar energy. The sun is undergoing a nuclear reaction from hydrogen to helium, continuously releasing huge energy, and constantly The radiant energy of the universe, this is solar energy. This kind of nuclear fusion reaction inside the sun can last for a long time, and it is estimated to be several billion to tens of billions of years. Compared with the limited life of human beings, solar energy can be said to be inexhaustible.

Infinite reserves: The energy emitted by the sun per second is about 118,668kw. The total amount of solar energy reaching the surface of the earth in a year is about 1,204,6596 trillion tons of standard coal, which is 10,000 times the current proven reserves of the world's main energy sources. Compared with the finiteness of conventional energy, solar energy is a renewable energy.

The universality of existence: Compared with other energy sources, solar energy can be seen everywhere. This provides convenience for some countries that lack energy.

Cleanliness of utilization: Solar energy, like wind energy, tidal energy and other clean energy sources, produces almost no pollution during its development and utilization.

2. LED light source

LED refers to the Light Emitting Diode. This kind of light source has the advantages of small size, long lifespan, high efficiency, low energy consumption, etc., and can be used continuously for up to 100,000 hours. In the future, LED light source applications will become mainstream in the lighting field. The LED light source is unidirectional, and the lighting effect is better than that of ordinary lamp holders, and there will be no diffusion phenomenon. The previous high-pressure sodium lamps have more serious light decay and have a short service lifespan, while LED lamps have a one-year light decay of 3%, the service lifespan is relatively long; LEDs are also very adaptable to the service life temperature, which can satisfy the use of street lights in the outdoor environment. Moreover, it can also have a better safety and reliability, so it is very important to ensure a better safety function when used outdoors, especially for public facilities such as street lights.

3. Combination of solar energy and leds

The key to the perfect combination of solar photovoltaic power generation technology and LED lighting is that the two are both direct current, low voltage and compatible with each other. Therefore, the combination of the two does not need to convert the direct current generated by the solar cell into alternating current, thus greatly improving the efficiency of the entire street lighting system. At the same time, with the help of grid-connected technology or the use of battery charging and discharging energy, its advantages are more obvious. With the in-depth research of related technologies, the luminous efficiency of LEDs is constantly improving, and ultra-high brightness LEDs will come out, which will inevitably replace ordinary lighting electric light sources, and save a lot of energy without pollution.

The newly upgraded LED combined with solar energy will further enhance the practicability of the lighting system. Because the working current of the LED is direct current, and the working voltage is low. Solar cells convert light energy into direct current electrical energy, and solar cell components can be combined in series and parallel to obtain the actual voltage required. These features match exactly with LEDs, and the combination of the two will achieve high energy efficiency, high safety performance and reliability, and realize energy-saving, environmentally friendly, safe and efficient lighting systems.

Solar led street lamps are popular, installed in many countries. With the development of the technology, the street lamp is getting more and more cost-effective. It's energy-saving and environmentally friendly. Compared to conventional street lights, it saves lots of electricity bills. It will bring unending benefits for citizens and the society.
