Advantages and disadvantages of Solar Road Studs and LED lights (1)

In the Stone Age, after mastering the method of using flames, human beings entered the era of free lighting at night.
In 1879, an inventor named Edison lit the first household electric light and let it enter thousands of households.

More than two hundred years have passed, and lighting technology has changed from incandescent lamps to energy-saving lamps. LED lamps are getting brighter and more energy-saving.
No matter what kind of lamp, it needs energy to light up, and the early stage of Solar Road Studs was criticized by people due to its low conversion rate of solar energy, high energy consumption of electric lamp itself, and short lighting time. But the emergence of LED lights has changed this embarrassing situation.
As the ancient poem said, LED lights and Solar Road Studs golden wind and jade dew meet, and they are better than countless people in the world.

Compared with traditional power generation methods, Solar Road Studs have the following advantages:
1. It is universal. There is no geographical limitation, where there is sun, there is solar energy. Solar energy can be used regardless of traffic conditions, whether the line is laid or not.
2. Harmless. Solar Road Studs are one of the cleanest sources of energy that emits no harmful gases and no carbon emissions. Today, when people pay more and more attention to the environment, people pay special attention to solar energy.
3. Adequate reserves. The solar radiation reaching the earth every year is equivalent to 130 trillion tons of coal, and the total reserves of coal that have been discovered in the world are about 1 trillion tons. While most of the solar energy used by Solar Road Studs is not conducive to conversion use, the total amount of solar energy reserves is large, and even when used in small amounts, the amount is large.
4. It is durable and renewable. As a representative of renewable energy, the solar energy used by Solar Road Studs is almost inexhaustible. Solar energy will exist as long as the sun exists.

Although the advantages are obvious, the disadvantages of Solar Road Studs are also obvious, such as low energy conversion rate, unstable energy supply, and photovoltaic environmental pollution, which has always been an obstacle to the development of solar energy. But the emergence of LED lights just solved these problems.
Solar Road Studs: low conversion rate, LED lights: high luminous efficiency.
Solar Road Studs are criticized for poor conversion rate and low charging efficiency. However, the high luminous efficiency of LED lamps makes up for the low conversion rate of Solar Road Studs.
The luminous efficiency of traditional incandescent lamps is 8-15lm/W, and the luminous efficiency of Solar Road Studs LED lamps is 70-120lm/w, which is about 8 times that of traditional incandescent lamps. That is, a 20-watt Solar Road Studs diode light is about as bright as a 160-watt incandescent bulb.
