Intelligent lighting solutions

The role of lighting in every family is self-evident. Regardless of the family, leaving the lighting, it is like returning to the ancient times hundreds of years ago, which brought a lot of inconvenience to our lives. It is undoubtedly a terrible thing for modern people to leave the life of lighting. Therefore, many scholars have defined the invention of incandescent lamps as one of the symbols of modern civilization. With the invention of incandescent lamps, various lighting devices began to enter thousands of households.

Thus, a lighting system has been formed in each family. Later, due to the use of various lamps, there was a certain change in the light and shade of the light. However, because it adopts the traditional local style, the control method of opening and closing, it restricts the fast-paced lifestyle of modern people, and also limits its application in modern homes.

With the development of science and technology and the improvement of people’s living standards, people have put forward new requirements for the family’s lighting system. It not only controls the lighting time and brightness of the lighting source, but also cooperates with the home subsystem to match different applications. The lighting scene, but also to consider the management intelligence and operation simplification and flexibility to adapt to future lighting layout and control changes. An excellent intelligent lighting system can enhance the quality of the home environment and ensure the comfort and health of family life. Therefore, the network switch replaces the traditional switch, and the intelligent lighting system replaces the traditional lighting system, which is an inevitable step in the process of home intelligence.

With the rise of the smart home industry, a new, full of humanized home smart lighting system will bring you all this.

Semi flex PCB is a flex-rigid PCB, typically 4 layers, made entirely of FR4. Unlike conventional flex-rigid PCBs, the flexing element is not polyimide but a thin FR4 core with two layers of copper specially treated to flex without cracking. A less robust solution uses a depth-milled layer rather than a core.

While this type of flexible circuit may be more expensive to design and produce, it does offer a number of important advantages. For instance, the reduced size makes it easier to fit more components into a smaller space. This can actually help to lower overall system costs. Additionally, because they require the need for fewer interconnects and related parts and components, these semi flexible pcb can also prove to be more reliable and require less maintenance in the long run.

As with all types of flexible circuit boards, the semi-flex PCB will perform well in even the harshest environments, especially those featuring extreme heat. A semi-flex  board is also easy to test, making it well-suited for prototyping.
