What are the differences between solar lights, fluorescent lights and LED lights?

In the field of modern lighting, solar lamps, fluorescent lamps and LED lamps are three common types of lighting products, which have significant differences in working principle, performance characteristics, and service life.

From the point of view of the working principle, there is a fundamental difference between the three. Solar lights rely on solar panels to absorb sunlight and convert it into electricity, stored in the battery, and then at night through the controller for the light source power supply, lighting.

Fluorescent lamp is through the mercury vapor discharge inside the tube to produce ultraviolet light, ultraviolet excitation of the inner wall of the tube phosphor emits visible light, and its work depends on the ballast to stabilize the current.LED lamps that is, light-emitting diodes, which is the use of semiconductor materials of the electro-optical effect.

In terms of energy consumption and energy saving, the difference is very obvious. The energy of solar lamps comes from solar energy, although its initial investment is relatively high, but the long-term use of almost no consumption of electricity, which is a model of energy saving. The energy consumption of fluorescent lamps is lower than that of traditional incandescent lamps, and generally speaking, the power consumption of fluorescent lamps is 2-3 times that of LED lamps under the same brightness. LED lamps are known for their low energy consumption, and their electro-optical conversion efficiency is very high, which can convert most of the electric energy into light energy, with less heat loss, and thus performs optimally in terms of energy saving.

The service life is also an important difference between the three. The life of solar lights is usually 3-5 years, the life of the LED light source can be up to 25000-50000 hours, the life of ordinary fluorescent tubes is about 8000-10000 hours, the life of the LED light is far more than the first two, the service life of high-quality LED lamps can be up to 50,000 hours or more, and even some products can reach 100,000 hours.
