With the development of science and technology and the improvement of human living standards, there are more and more types of lamps and lanterns. Among them, LED lamps are widely used. LED lights are not only mild but also have a wide range of lighting. The most important thing is energy saving. Next, let me take you to understand the advantages and disadvantages of LED lamps.
Advantages of LED lights
Advantages 1, LED lamp body is very small.
LED lights are very small, very delicate LED chips encapsulated in transparent epoxy, so it is very small, and very light, in production and application can save a lot of material and space.
Advantages 2, The energy consumption is very low.
The working voltage and current of the LED lamp are 2-3.6 V and 0.02-0.03 a respectively. In other words: it consumes no more than 0.1 W of electricity, uses more than 90% less energy than the same efficiency of incandescent lamps, and energy-saving lamps with more than 70%. Therefore, only the LED can be called a real energy-saving light source!
Advantages 3, LED light is strong and durable.
The LED chip is completely encapsulated in epoxy. The tiny epoxy particles are extremely difficult to break, there is no loose part of the entire lamp, and the chip inside is extremely difficult to break and has a little thermal effect that can evaporate and fuse. These features make LEDs hard to break. Compared with ordinary light bulbs, and fluorescent lights, LED can be said to be impregnable, rugged times numerous times, and durable times numerous times.
Advantages 4, LED lamp long service life.
Under the right current and voltage, LED lamp life can reach 100,000 hours, that is, the theoretical product life of more than 10 years, than other types of lamps with longer life.
Advantages 5, Safe and low voltage.
LED lights use a low-voltage DC power supply (can be converted from AC to DC), with a power supply voltage between 6-24V, due to different products vary. In short, it is safer than a high-voltage power supply DC power supply, especially suitable for homes and public places.
Advantage 6, LED lights wide range of applications.
Because of its small size, each unit LED chip is 3-5mm square or circular, so it is more suitable for the preparation of complex molding process devices. For example, the manufacture of soft, flexible tubes, light belts, and special-shaped flowers, is currently only suitable for LED.
Advantages 7, LED lamps have more colorful.
In the past, the market of lamps and lanterns color is very simple, to achieve the goal of color, one is on the surface of lamps and lanterns brush paint or covered colored film, and the other is in lamps and lanterns filled with inert gas luminescence, so the richness of color is limited. LED is a digital control, light-emitting chips can currently emit a variety of colors, including red, green, and blue tricolor, it is this tricolor, through the system control, can restore the colorful Buddhist cosmology.
Advantages 8, Less heat dissipation.
LED is a more advanced cold light source, it does not unlike incandescent lamps, and fluorescent lamps as a large amount of infrared and ultraviolet radiation, especially suitable for cultural relics, jewelry, high-end cosmetics, and other valuables lighting. There is almost no incandescent lamp-like current heat effect, will not be heat expansion and contraction of the impact of the bubble. Will not make the light bulb yellow, will not make the lamp accelerate aging, and will not cause the greenhouse effect on the surrounding environment.
Advantages 9, Less environmental pollution.
The environmental protection of LED is mainly manifested in three aspects:
First, there is no harm from metallic mercury. Unlike fluorescent lamps, LED lamps do not use high-risk mercury, and there are no public hazards such as mercury ions that can leak out during manufacturing or when a bulb is damaged, such as phosphors.
Second, LED epoxy are organic macromolecule with excellent physical chemistry properties after curing, high bonding strength to wafers and metals, hardness and flexibility, and stability to salts and alkali as well as most solvents, not easy to damage, even if damaged or aging can also be recycled, will not pollute the environment.
Third, in LED lamps and display particle layouts, the resulting light is generally scattered, rarely light pollution.
Advantages 10, More cost savings.
Compared to incandescent lamps, fluorescent lamps, and LED lamps procurement price is higher. However, because LED energy consumption is particularly low, in the long term can save a lot of electricity, and can save the investment in light replacement, so the cost of integrated use is more cost-effective.
Disadvantages of LED lights
Disadvantage 1, LED lamps cannot completely replace incandescent lamps.
The luminous flux, light effect, and color rendering of LED lights are all good, but they are currently too expensive and will not decline in recent years. However, the cost of replacing incandescent lamps can be reduced by increasing the luminous flux of the product.
Disadvantage 2, LED cannot be used as a simple light source.
The purpose of LED lights is to drive power, optics, and heat conduction.
Disadvantage 3, LED lights will also heat up and need to be dissipated.
Advantages and disadvantages of energy-saving lamps and LED lamps With the development and advancement of technology, products are constantly being improved and upgraded. Lamps are essential household items in every home. Therefore, everyone must first understand the relevant information when purchasing.
Summarize:
The above is relevant content on the advantages and disadvantages of LED lights. Although LEDs have many advantages, they cannot completely replace incandescent lamps. The price of incandescent lamps is cheaper than LED lights. With the development and progress of technology, energy-saving lamps and LED lights are constantly improving. Upgrading can give you more options.
