Scene control of intelligent lighting (two)

Office

Using infrared sensor with automatic fill function to control the lighting, with light adjustable ballast used together. When the light slowly darken below the sensor set value, sensor switch will turn on the lighting, but lighting is not immediately lit, but according to the brightness of the environment declined much to automatically add to the appropriate illumination, and gradually achieve 100% brightness, minimize the damage to the eyes light changes during work.

When no one is working in the office, the sensor automatically turns off the lights.

Toilet

Public toilet lighting and ventilation equipment using microwave sensor control. Usually the public toilet is divided into several compartments, only need to install a microwave sensor can control the entire area of lighting and ventilation equipment. This is because the microwave sensors emit ultrasonic waves through the thin glass and wood, so that people in the toilet activities will be detected.

The sensor is based on whether or not a person is in the sensing range to decide whether to turn on and off the illumination and the exhaust fan, and is free from the interference of the temperature.

2 the same place, different scenarios of lighting planning

At the same place, the lighting planning of different scenes is based on the requirements of customers, in the same place to achieve different scene lighting. This scenario can be realized by the communication mechanism of the bus. A case study of the communication bus. This is a group address based communication, the basic principle is as follows: each lighting control device has three address, group address, physical address and switch address. The group address for each device is different, but the physical address can be the same.

When the switching device is pressed, the lighting device with the same group address can receive the information through the bus. The lighting device which is different from the switch group address does not receive the information. The concept of "group" has realized the function of "Scene", for example, by grouping the lights in the multimedia classroom, it can be realized by several buttons, which is convenient to realize "class", "speech", "slide show" and so on.
