LED lighting equipment is an important component of smart lighting systems. Compared with traditional light sources, LED has higher energy efficiency, longer lifespan, and better color performance. In smart lighting systems, LED lighting equipment can be seamlessly connected to intelligent controllers and sensors, achieving intelligent control and management. CSP LED has great advantages in lamp design, such as utilizing the small light source and single-sided light output characteristics of CSP. By using CSP densely arranged combinations with different color temperatures, it is possible to achieve high light quality requirements for indoor smart lighting, such as small light source emitting surface, adjustable light and color, uniform light spot, and consistent mixed light color.
