Centralized control illuminating lamp employing centralized power supply

Abstract

The invention relates to a centralized control illuminating lamp employing centralized power supply. The centralized control illuminating lamp comprises a two-bus communication module, a drive module, a control module and a fault detection module. The illuminating lamp can achieve two-bus constant-current supply, does not need to be provided with the power supply, and has a self-checking function; the conditions of open and short circuits in a circuit can be monitored in real time; the detection result is uploaded to a monitoring equipment terminal through the two-bus communication module; and monitoring and overhauling work can be finished only by a little manpower. The centralized control illuminating lamp has the advantages that a power supply circuit is simplified; the overhaul efficiency is improved; and the human cost is reduced.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an emergency lighting fixture used in the field of large-scale engineering fire protection. technical background [0002] With the development of the economy, the country has built many large-scale projects in recent years, such as high-speed rail, subway, airport, etc., especially in the field of high-speed rail and subway rail transit, investment has increased, and many railways have been built. The laying of tracks inevitably needs to cross mountains or cross rivers. Special subway projects are basically underground, so lighting is of great significance to driving safety. Projects such as subways and high-speed rails have long distances and many on-site equipment. At present, traditional emergency lighting fixtures are mainly self-contained power supply types. The batteries and inspection devices of this kind of lighting fixtures are installed inside or near the lighting fixtures, resulti...

AI Technical Summary

Problems solved by technology

Projects such as subways and high-speed rails have long distances and many on-site equipment. At present, traditional emergency lighting fixtures are mainly self-contained power supply types. The batteries and inspection devices of this kind of lighting fixtures are installed inside or near the lighting fixtures, resulting in large, bulky lighting fixtures and long battery life. It is inconvenient to replace after arrival, and the inspection of the running status of the lamps is time-consuming and labor-intensive, especially when the lamps fail, there will be great safety hazards if they are not checked in time
