Why do LED lights replace incandescent lights, the top ten LED trends!
Modern civilization really owes thanks to the American inventor Thomas Edison for making the first commercially valuable white light that brought light to human beings.However, Conrad Hubert deserves the same respect. He invented the flashlight 100 years ago, when he emigrated from Russia to the United States.
In the early days, the light source of the flashlight was a vacuum bulb, which used a filament inside. So sometimes we used it, and the filament broke. I believe that the big one encountered this phenomenon. Sometimes it bounces with a finger, and sometimes it bounces. That means the light source should be like an incandescent lamp, but now the flashlight uses LED light source, which is a rechargeable power source.
The Chinese name of an LED is a light emitting diode junction.It is a solid-state semiconductor device that converts electrical energy into visible light, which directly converts electricity into light.The heart of an LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other end is connected to the positive pole of the power supply, so that the entire wafer is encapsulated with epoxy resin.The principle is too complex, but now more and more luxury brands are starting to use LED as a headlight source. In the environment advocating energy conservation and environmental protection, the promotion of LED always means a general trend. Ten advantages of LED lamps:
Advantages 1. Small body
LED lamp is a very small, very fine LED wafer encapsulated in a transparent epoxy resin, so it is very small, very light, and can save a lot of material and space in its manufacture and application.
Advantages 2. Very low energy consumption
In general, the working voltage of the LED lamp is only 2~3.6V, and the working current is only 0.02~0.03A. That is to say, it consumes no more than 0.1W of electricity and consumes more than 90% less energy than incandescent lamps of the same light efficiency and 70% less than energy-saving lamps.So only LEDs can be truly energy efficient!
Advantages 3. Strong and durable
LED wafers are fully encapsulated in epoxy resin.Compact epoxy particles are extremely hard to break, and there is no loose part of the lamp; the wafers inside are extremely hard to break, and have little heat effect and can evaporate and break.These features make it difficult to damage the LED.Compared to ordinary bulbs, fluorescent lamps, LED is as solid as gold soup, numerous times stronger and durable.
Advantages 4. Long life of LED lamp
Under the right current and voltage, the life of LED lamp can reach 100,000 hours, that is, the product life can theoretically exceed 10 years, which is longer than other types of lamp.
Advantages 5. Safe low voltage
LED lamps use a low voltage DC power supply (which can convert AC rectifier to DC) with a power supply voltage between 6 and 24V, which varies from product to product.In short, it applies a DC power supply which is safer than high voltage power supply, especially for home and public places.
Advantages 6. Wide range of applications
Because of its compactness, each unit LED chip is 3~5mm square or circular, so it is more suitable for the preparation of devices with complex styling process.For example, to make soft, bendable lamp tubes, lamp strips, special-shaped flowers, only LED is currently suitable.
Advantages 7. Richer colors
Previously, the color of lamps on the market was very single. In order to achieve the purpose of color, one is to brush paint on the surface of the lamps or to cover the colored sheets, the other is to illuminate the lamps with noble gases, so the richness of color is limited.LED is a digital control. At present, the light emitting chip can emit a variety of colors, including red, green and blue. With these three colors, system control can restore the colors of the world.
Advantages 8, less heat emission
LED is a more advanced cold light source. It does not radiate a lot of infrared and ultraviolet rays like incandescent lamps and fluorescent lamps. It is especially suitable for lighting valuables such as cultural relics, jewelry and high-grade cosmetics.There is almost no electrothermal effect like incandescent lamp, and the bulb will not be blown up by expansion or contraction of heat.No yellowing, no accelerated aging, no greenhouse effect on the surrounding environment.
Advantages 9. Less environmental pollution
The environmental protection of LED is mainly manifested in three aspects:
One is that there is no harm from mercury metals.Unlike fluorescent lamps, LED lamps do not use high-hazard mercury, and there are no public hazards such as mercury ion leakage during lamp manufacturing or after breakage.
Second, the epoxy resin used to make LED is an organic high molecular compound, which has good physical and chemical properties after curing. It has high bonding strength to wafer and metal, is hard and flexible, is stable to saline-alkali and most solvents, and is not easy to damage. It can be recycled and reused even after damage or aging, and will not cause environmental pollution.
Thirdly, the particle layout of LED lamps and displays generally results in scattered light, which rarely produces light pollution.
Advantages 10. Save money
LED lamps are purchased at a higher price than incandescent lamps, fluorescent lamps.However, due to the extremely low energy consumption of LEDs, a large amount of electricity bills can be saved in the long run and the investment of changing lights can be saved, thus making the integrated use more cost-effective.
