Comprehensive comparison of solar street lights and ordinary street lights
1. Comparison of working principles LED is a light-emitting diode, which is a solid-state semiconductor device that can directly convert electrical energy into visible light. The LED solid-state package is a cold light source type. So it is convenient to transport and install the electrodeless lamp consists of three parts: high frequency generator, coupler and bulb. It is inductively coupled into the lamp through the electromagnetic field of the high-frequency generator, so that the gas avalanche ionization in the bulb is formed to form plasma. The plasmonic excited atoms radiate ultraviolet light when they return to the ground state. The phosphors on the inner wall of the bulb are excited by ultraviolet light to produce visible light. The actual luminous efficiency of the product is about 65Lm/W, which cannot reach the luminous efficiency of sodium lamps.
2. Compared with 12V low-voltage power supply in terms of safety performance, 220V AC is used without any potential safety hazards, which has stricter requirements for line safety. The longer the use time, the higher the potential safety hazards.
3. Compared with the service life of solar panels, the service life is 25 years. Up to 100,000 hours, the gel battery is 5-8 years, and the design life of the electrodeless lamp is 10,000 hours
4. The biggest feature of energy saving and environmental protection comparison is the use of solar energy to be self-sufficient and energy-saving; no harmful substances, no pollution; no stroboscopic LED lights, stable light intensity 2. The oscillating frequency of 65mHz is easy to generate bad magnetic fields and cause electromagnetic interference, so it has been banned in western countries. 5. Compared with independent installation and maintenance, it is not restricted by cables; The lighting time is long, and automatic control can be realized without additional investment; the later maintenance is simple and convenient. The first installation must be uniformly debugged. If a problem occurs in a certain position, multiple street lights may not work. Later maintenance personnel need to be familiar with the pre-buried situation of underground cables. Once the location is fixed, it will be very difficult to change it. To achieve automatic control, it is necessary to install a clock device. Final conclusion With the significant reduction in the cost of solar panels, the improvement of battery performance, and the popularization of LED light sources, it is equivalent to ordinary street lights and the advantages of solar street lights. It is already obvious that the more complex the conditions of use, the longer the light time, the more it can reflect its advantages. The cost can basically be recovered within 2 years.
And there are many incomparable advantages: no need to dig trenches to lay wires, each lamp can be installed after pouring the cement foundation; each lamp is an independent lighting power generation system, which automatically turns on and off without special control; does not consume conventional energy; explosion-proof The safety factor is high. If there is a problem, you only need to repair the problem lamp, and you don’t need to check the cables to find them one by one. In addition, the concept of energy saving and environmental protection is deeply rooted in the hearts of the people, not only to calculate economic accounts, but also to consider social benefits. From the current situation, as long as the local light conditions allow, solar street lights have become the first.
