Do LED lights need a circuit board?

Nowadays, LED lamps have become the mainstream of lighting, and there are very few households using incandescent lamps. Its main advantage is that LED lamps are more energy-efficient. Under the same luminous efficiency, LED lamps consume more than 70% less electricity than incandescent lamps. The lifespan of LED lamps is longer than that of incandescent lamps. Anyone who has used incandescent lamps knows that the tungsten filaments inside will burn out after a short period of time. According to statistics, the average lifespan of incandescent lamps is about 1,000 hours, that is, on average every day. For 10 hours, it can only be used for about 100 days, which is more than 3 months. The service life of LED lights can reach 100,000 hours, that is, the theoretical service life can reach 10 years. Some people would say, how can it be so long? It will be broken after a few months of use. This is only a theoretical value. The actual life is related to the design of the LED lamp bead driver Aluminum 3.0W LED board. Many manufacturers save costs and simplify the design, which leads to the instability of the current and voltage of the LED lamp. Lifespan is reduced.
