Lamps are one of the indispensable items in home improvement. When purchasing lamps, in addition to considering the factors of the house itself, you must also consider the performance of lamps. Some consumers will understand the advantages of lamps before purchasing them. What are the advantages of lamps?
The led light is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then connects the chip and the circuit board with silver or gold wires, and is sealed with epoxy resin around it to protect the inner core wire. role, and finally install the shell.
1. The lamp body is small: the LED lamp is a very small and very fine LED chip encapsulated in a transparent epoxy resin, so it is very small and very light, which can save a lot of materials and space in production and application. LED is a more advanced cold light source, especially suitable for the lighting of valuables such as cultural relics, jewelry, and high-end cosmetics. There is almost no current heating effect like incandescent lamps, and it will not be affected by thermal expansion and cold contraction. It will not make the bulb yellow, will not accelerate the aging of the lamp, and will not cause a greenhouse effect to the surrounding environment.
2. Low energy consumption: The working voltage of the led lamp is generally only 2 to 3.6V, and the working current is only 0.02A to 0.03A. That is to say, it consumes no more than 0.1W of electricity, which is less than that of incandescent lamps with the same luminous efficiency. More than 90%, more than 70% less than energy-saving lamps. The purchase price of LED lamps is high, but because the energy consumption of LEDs is very low, it can save a lot of electricity bills in the long run and save the investment in changing lamps, so the comprehensive use cost is more cost-effective.
3. Sturdy and durable: The led chip is completely encapsulated in epoxy resin. The small epoxy resin particles are extremely difficult to break, and the entire lamp body has no loose parts; the chips inside are extremely difficult to break, and there is little thermal effect and may volatilize and fuse. These features make LEDs difficult to damage. Compared with ordinary light bulbs and fluorescent lamps, leds are indestructible, sturdy and durable.
4. Long service life: Under the appropriate current and voltage, the service life of the led lamp can reach 100,000 hours, that is, the theoretical product life can reach more than 10 years, which is longer than other types of lamps. The led lamp uses a low-voltage DC power supply (which can rectify alternating current into direct current), and the power supply voltage is between 6-24V, which varies from product to product. In short, it applies a DC power supply that is safer than a high-voltage power supply, and is especially suitable for homes and public places.
