Aluminum driverless PCB board for LED lighting

What are the disadvantages of LED?

Although Aluminum base board led lights have many advantages, no matter how perfect things are, they have their own shortcomings, and Aluminum base board led lights also have certain shortcomings. The disadvantages of Aluminum base board led lights are as follows:
1. Although the light attenuation of Electronic Components led is very low, this is basically for the led lights on the high-power Aluminum LED boardh, while the light attenuation of low-power led lights is still relatively large, and this low power The useful life of LED lights is far from that of high-power lights.
2. The light source of the led lamp is white light. Due to the individual defects in the cheap pcb manufacturing process and the matching error of the lens, it is easy to form a yellow circle when the led lamp is in use, which will affect the lamp The irradiation effect.
3. There is mercury pollution after low cost pcb manufacturing and use and disposal. This mercury pollution has great harm to the natural environment. At present, Western countries attach great importance to mercury pollution, and many people in China are increasingly aware of the harmfulness of mercury pollution.
4. In fact, this kind of Aluminum base board led light is easy to be damaged, short life, energy saving but no money. This sentence is the most true portrayal of led light.
