Advantages and disadvantages of LED energy-saving lamps
1. Advantages of LED energy-saving lamps: LED energy-saving lamps save power, have high brightness, project far light, have good light projection performance, and have a wide range of voltages. , Colorful, low loss, low energy consumption, green and environmental protection, suitable for long-term lighting in families, shopping malls, banks, hospitals, hotels, restaurants and other public places. Compared with incandescent tubes or low-voltage fluorescent tubes, the stability and long life of LEDs are obvious advantages.
Second, LED energy-saving lamps features:
1. Energy saving. The energy consumption of white LEDs is only 1/10 of incandescent lamps and 1/4 of energy-saving lamps.
2. Longevity. The lifespan can reach more than 100,000 hours, which can be described as once and for all for ordinary household lighting.
3. It can work at high speed. If the energy-saving lamp is frequently started or turned off, the filament will turn black and quickly break down.
4. Solid-state packaging, belonging to the type of cold light source. Therefore, it is very convenient to transport and install, and can be installed in any miniature and closed equipment. It is not afraid of vibration and basically does not need to consider heat dissipation.
5. LED technology is progressing with each passing day, its luminous efficiency is making an amazing breakthrough, and the price is constantly decreasing. An era of white LEDs entering the home is rapidly approaching.
3. Analysis of advantages and disadvantages:
1. The energy-saving lamps start slowly.
2. Energy-saving lamps are bright-line spectrum (discontinuous), so the usual energy-saving lamps are violet, and things will be seriously discolored when viewed under energy-saving lamps. Blues will turn purple, and reds and yellows will look more vibrant. Therefore, it is not advisable to use energy-saving lamps in the workplace with color matching.
When the ballast used in the energy-saving lamp generates instantaneous high voltage, it will generate a certain amount of electromagnetic radiation. The electromagnetic radiation of energy-saving lamps also comes from the ionization reaction between electrons and mercury gas. At the same time, energy-saving lamps need to add rare earth phosphors. Because rare earth phosphors themselves are radioactive, energy-saving lamps will also produce ionizing radiation (ie, radioactive nuclear radiation). Compared with The uncertainty of electromagnetic radiation damage to the human body, and the damage of excessive radiation nuclear radiation to the human body is more worthy of attention. Features of inferior energy-saving lamps:
1. The power of the energy-saving lamps is unqualified.
2. The initial light efficiency of the energy-saving lamps is unqualified.
3. The mechanical strength is unqualified.
4. The harmonics of energy-saving lamps are unqualified.
5. The color characteristics of the energy-saving lamps are unqualified.
