History of Lamp Beads 1W LED

The concept of LED (Light Emitting Diode) technology was first proposed by Nick Holonyak Jr. in 1962. However, it was not until the late 1970s that LED technology began to be commercialized. The early LED products were mainly used in indicator lights and small displays. In the 1990s, with the continuous development of LED technology, the brightness and color of LEDs improved significantly, and their applications expanded to outdoor lighting, automotive lighting, and other fields. The lamp beads 1W LED, as a type of high-power LED, emerged in the early 2000s. With the continuous optimization of the LED chip and the improvement of the heat dissipation technology, the 1W LED lamp beads have become a mainstream product in the lighting industry. In recent years, with the increasing demand for energy conservation and environmental protection, the market demand for lamp beads 1W LED has continued to rise.
