Lighting and emergency-meeting dual-purpose lamp applicable to DC low voltage

Abstract

The invention discloses a lighting and emergency-meeting dual-purpose lamp applicable to DC low voltage, which comprises an AC / DC conversion device and a dual-purpose lamp body, wherein the AC / DC conversion device is connected to 110-280V alternating current, then the output end of the AC / DC conversion device is connected to the dual-purpose lamp body, the AC / DC conversion device can use alternating current and direct current simultaneously, and the dual-purpose lamp body can support the 110-280V alternating current and 1.5-36V DC low voltage. The dual-purpose lamp disclosed by the invention can satisfy two functions of lighting and emergency meeting simultaneously, and realizes a purpose that two requirements of lighting and emergency meeting can be satisfied by only designing one power supply system in a building.

Description

technical field [0001] The invention belongs to the technical field of circuit design, and in particular relates to an emergency dual-purpose lamp suitable for DC low voltage. Background technique [0002] At present, the lighting circuits and emergency circuits used in public places such as schools and shopping malls are separated. Because lighting and other common electrical circuits are national standard 220V alternating current circuit systems, while emergency circuits are ordinary direct current circuits. Therefore, when building high-rise buildings such as schools and shopping malls, people often need to design two circuit layouts. Therefore, it is in line with the market demand to design a device so that the building can design a set of circuits, and the circuit can simultaneously meet the situation of lighting common electricity and emergency electricity consumption; in addition, it is not enough to only need the above-mentioned device, because 1. Existing lighting...

Problems solved by technology

Therefore, it is in line with the market demand to design a device so that the building can design a set of circuits, and the circuit can simultaneously meet the situation of lighting common electricity and emergency electricity consumption; in addition, it is not enough to only need the above-mentioned device, because 1. Existing lighting bulbs and lamps are only suitable for one voltage, such as 220V and other single voltage

Therefore, the lighting installed in high-rise buildings is often only suitable for 220V voltage, and when a fire or flood occurs in the building, or the internal circuit of the building fails, people can only rely on the emergency lighting inside the building, and the emergency lighting placed inside the building The lighting is installed at a specific position in the fire exit. When the general lighting is out of power, the brightness of the emergency light can only meet people's basic escape light source. In the modern escape demand, the existing emergency light is obviously too weak, which easily leads to escape. Stampede accidents or low escape efficiency when people are in a hurry are prone to confusion

2. Existing indoor lighting for household, commercial or public lighting only has the function of normal lighting. When there is a power failure, the indoor lighting is extinguished, causing the work to stop instantaneously, and the work is interrupted. It is inconvenient or only necessary to deal with follow-up work. Carrying out simple tidying up work under natural light is likely to cause confusion or impossibility of work. This kind of lighting defect needs to be solved
