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

Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in detail, as figure 1 As shown, the present invention includes four modules: a two-bus communication module, a drive module, a control module and a fault detection module. Provide the preferred circuit structure of each module in the embodiment, as Figure 2 to Figure 5 shown.

[0034] Embodiment: For the convenience of description, in this embodiment, only the power supply and detection process of a single lamp is described in detail.

[0035] When the system is working, the input voltage of BUSA and BUSB is DC voltage, which is converted into unidirectional pulsating bus voltage through TVS tube V0, EMI suppression circuit and rectification circuit, and provides bus power supply for the light-emitting diodes in the lamps.

[0036] At the same time, the bus voltage signal is used as the input signal of the auxiliary power supply circuit, code receiving circuit a...

Abstract

The invention relates to a lighting fixture with centralized power supply and centralized control, which includes a two-bus communication module, a drive module, a control module and a fault detection module. The function can monitor the open circuit and short circuit in the circuit in real time, and upload the detection result to the monitoring equipment end through the two-bus communication module, and only a small amount of manpower is needed to complete the monitoring and maintenance work. The lighting fixture has the advantages of simplifying a power supply circuit, improving maintenance efficiency and saving labor costs.

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...
