Introduction

GB/T 30104 "Digital Addressable Lighting Interface" (all parts) describes a method for controlling electronic lighting equipment via digital signals.

The proposed bus system will consist of the following components.

Part 103 provides general requirements for control devices; Part 104 provides general requirements for control equipment.

General requirements for wireless and other wired system components; Part 150 specifies the requirements for auxiliary power supply, which may be independent.

It can be built-in or integrated into a control device or control equipment.

Special requirements for control devices for specific types of light sources.

Special requirements for each type of input device.

Use all the parts together.

GB/T 30104 is published as a series of standards, divided into several parts, providing specific regulations for various types of equipment, with the aim of facilitating the standardization process.

Use and maintenance.

The structure and relationships of the series of standards are shown in Figure 1 below.

3 Terms and Definitions

The terms and definitions defined in GB/T 30104.101 and GB/T 30104.102, as well as the following terms and definitions, apply to this document.

load shedding

Temporarily reduce light output to reduce mains power consumption.

Normal light output

The expected light output represents the "actualLevel" variable, which is determined by the currently selected dimming profile.

The final light output obtained after adjusting the normal light output using a reduction factor.
