Advantage 2. Extremely low energy consumption: generally, the working voltage of LED lamps is only 2~3.6V, and the working current is only 0.02~0.03A, that is to say, it does not exceed 0. 1W, which is more than 90% less than that of incandescent lamps with the same light efficiency and more than 70% less than that of energy-saving lamps. Therefore, only LED can be called a real energy-saving light source!
Advantage 3: Sturdy and durable: LED chips are completely encapsulated in epoxy resin. Small particles of epoxy resin are extremely difficult to break, and there is no loose part in the whole lamp body; The chip inside is extremely difficult to break, the thermal effect is very small, and it may evaporate and fuse. These characteristics make LED not easy to be damaged. Compared with ordinary light bulbs and fluorescent lamps, LED is impregnable and durable countless times.
Advantage 4. Long service life of LED lamps: Under proper current and voltage, the service life of LED lamps can reach 6.5438+10,000 hours, that is, in theory, the service life of products can reach more than 654.38+ 00 years, which is longer than other types of lamps.
Advantage 5. Safe low voltage: LED lamp adopts low voltage DC power supply (which can rectify alternating current into direct current), and the power supply voltage is between 6 and 6~24V, which varies from product to product. In a word, it uses a safer DC power supply than a high-voltage power supply, which is especially suitable for home and public places.
Advantage 6. Wide application range: due to its small size, each unit LED chip is 3~5mm square or round, which is more suitable for preparing devices with complicated molding process. For example, the manufacture of soft and flexible tubes, light strips and special-shaped snuff is currently only applicable to LED.
Advantage 7. More colorful: In the past, the lamps on the market had a single color. In order to achieve the purpose of color, one is to smear or cover the surface of lamps, and the other is to fill inert gas into lamps to emit light, so the richness of color is limited. LED is digitally controlled. At present, light-emitting chips can emit a variety of colors, including red, green and blue. It is with these three colors that the colorful world can be restored through system control.
Advantage 8. Less heat: LED is a more advanced cold light source, which does not radiate a lot of infrared rays and ultraviolet rays like incandescent lamps and fluorescent lamps, and is especially suitable for lighting valuables such as cultural relics, jewelry and high-end cosmetics. There is almost no current thermal effect like incandescent lamp, and it will not be affected by thermal expansion and contraction. Will not make the bulb yellow, accelerate the aging of lamps and lanterns, and will not have a greenhouse effect on the surrounding environment.
Advantage 9. Less environmental pollution: the protective effect of LED on the environment is mainly manifested in three aspects:
First, there is no harm of metallic mercury. Unlike fluorescent lamps, LED lamps do not use highly hazardous mercury, and there will be no public hazards such as mercury ions and fluorescent powder that may leak during the manufacturing process or after the bulb is damaged.
Secondly, the epoxy resin used to manufacture LED is an organic polymer compound. After curing, it has good physical and chemical properties, high adhesion strength to wafer and metal, hard and flexible, stable to salt and alkali and most solvents, and not easy to be damaged. Even after being damaged or aged, it can be recycled without polluting the environment.
Thirdly, the light generated by the particle layout of LED lamps and display screens is generally scattered and rarely causes light pollution.
Advantages 10. Cost saving: Compared with incandescent lamps and fluorescent lamps, the purchase price of LED lamps is higher. However, because the energy consumption of LED is particularly low, it can save a lot of electricity bills and investment in changing lamps in the long run, so the comprehensive use cost is more cost-effective.
