Guide: How long does the LED lamp last? The LED lamp consumes less power than the ordinary lamp. After using the LED lamp, the electricity cost per month is much less. There is an important difference in the protection of the environment. Let LED lights become more and more popular. But everyone also needs to know that LED lights are the same as people. It has a long life. If the use of LED lights exceeds its life, its energy-saving ability will be greatly reduced or no longer energy-saving. Then, how long is the life of LED lights? Let's talk about the difference between LED lights and energy-saving lamps.

How long does the LED lamp last?
The theory is a 30,000h-50000h (semiconductor diode).
1. How long does the LED lamp last? The chip is packaged (different environment, affecting life. It is impossible to know how the lamp is low, this is a standard)
2, the long life of LED lights, power drive power (electronic products, generally 2 years,)
3, the long life of LED lights, lamps, the entire life is a very long time, usually 2-3 years.
The difference between led light and energy saving light
The difference between led lights and energy-saving lamps, the life of ordinary LED lights can be used for more than 50,000 hours, and some special LED lights can reach 100,000 hours. Of course, the life of the LED lamp is determined by the chip and the driving factor. However, since the LED lamp does not have the problem of the filament being blown, the life of the LED lamp is much higher than that of other lamps.
The life of a general energy-saving lamp is about 5,000 hours, and it has reached more than 8,000 hours. That is, the energy-saving lamp needs to be replaced after one year.
In contrast, we can see that LED lights can be replaced after more than five years, which greatly saves the cost of replacing the bulbs.

What is led energy saving lamp?
LED energy-saving lamps are a new generation of illumination sources after compact fluorescent lamps (ie, ordinary energy-saving lamps).
An LED, a semiconductor light-emitting diode, is a solid-state semiconductor device that converts electricity directly into light. LED energy-saving lamp is a high-brightness white LED light source with high luminous efficiency, low power consumption, long life, easy control, maintenance-free, safe and environmentally friendly. It is a new generation of solid cold light source with soft, colorful, colorful and low light color. Loss, low energy consumption, green and environmental protection, suitable for long-term lighting in homes, shopping malls, banks, hospitals, hotels, restaurants and other public places. No flash DC, it has a good protection for the eyes, it is the best choice for desk lamps and flashlights.
Light-emitting diode, the heart of the LED is a semiconductor wafer. One end of the wafer is attached to a bracket, one end is a negative pole, and the other end is connected to the positive pole of the power source, so that the entire wafer is encapsulated by epoxy resin. The semiconductor wafer consists of two parts, one part is a P-type semiconductor, in which the hole dominates, and the other end is an N-type semiconductor, which is mainly electrons here. But when the two semiconductors are connected, they form a PN junction. When a current is applied to the wafer through the wire, the electrons are pushed toward the P region. In the P region, electrons recombine with the holes, and then the energy is emitted in the form of photons. This is the principle of LED illumination. Because the LED lamp does not generate heat, the electric energy is converted into light energy as much as possible, and the ordinary lamp converts a lot of electric energy into heat energy due to the heat generation, which is wasted. In contrast, LED lighting is energy efficient.
LED energy-saving lamps are a category of LED general-purpose lighting, and their names are derived from traditional lighting bulbs and energy-saving lamps. The shape of the LED energy-saving lamp is similar to that of the traditional energy-saving lamp, and the shape can satisfy the traditional aesthetics of the consumer. The characteristics of LED energy-saving lamps: low cost, high luminous efficiency, large luminous area, no glare, no ghosting.
