Intelligent control technology of LED landscape lighting belongs to the field of analog or digital technology, or microcomputer control technology, most of which are compact or embedded systems. Features:

⑴High reliability and good price;

⑵ Often the batch size is small;

⑶ There are many variations and names;

⑷ Both single lamp control and group control mode are available;

⑸Many non-standard designs;

⑹ There are many long or extra-long lamps (such as long light strips and many linear layouts of wall lamps);

Therefore, there are many differences from LED display technology.

Changing control mode

According to the requirements of landscape beautification, the changing control mode should be colorful, with beautiful melody, cheerful rhythm, and sometimes it should have a strong and stimulating visual effect that is shocking.

Control of color composition

Based on the advantages of LED's good controllability and rich color composition, according to the principle of three primary colors plus digital grayscale control technology, in principle, it is possible to evolve almost any color that exists in nature.

For example, if only two-level grayscale control is used for three-primary color LED, i.e., bright and dark, eight color evolutions can be achieved;

Another example: three-primary color LED, using three-level grayscale control, namely: bright, medium, dark, can achieve 27 color changes;

Another example: if the three-primary color LED adopts 8-digit grayscale control, the color variety has reached an astonishing level, reaching 16.77 million, and you can't even name each color. Of course, too many colors may not necessarily make sense for landscaping.

Electronic control features

At present, the electronic control structure of LED lamps mainly includes five categories or more: single lamp control, group lamp control, long or ultra-long span lamp control, sound control, and induction control.

The focus of the optimized design of LED microelectronic control circuits is: reliable, cost-effective, and using universal components. The control of long or ultra-long span lights has the following requirements: light strips of tens of meters, hundreds of meters, or even more than a kilometer or point light sources in linear layout. The goal of the optimized design is also: in terms of motion control, the colors should be rich and varied, with both jumps and gradients, and at the same time, the communication wires should be minimized. Of course, there are many specifications that can be adopted, such as: C-BUS system, IEEE Standard 802, etc., but they may not be used in many occasions, and the price is high and the market competitiveness is poor. For this reason, our company has successfully developed a new system with superior cost performance.
