What is an emergency light? Simply put, the lamps that naturally light up in the event of a power failure are called emergency lights. The function of emergency lights should not be underestimated. This is still very helpful for coping with emergency needs. However, many people install them. I don't know, in fact, there are specifications, which are different from ordinary lights.

What is an emergency light?
Emergency lighting is also an emergency lighting. Emergency lighting is a type of lighting that can effectively illuminate and display evacuation passages or can continue to illuminate without interruption when the normal lighting power fails. It is widely used in public places and places with uninterrupted lighting.
The emergency lighting fixture is composed of light source, light source driver, rectifier, inverter, battery pack, and sign lamp housing. Normally, the 220V mains power source drives the light source to normally illuminate through the light source driver. At the same time, the battery pack is supplemented by the rectifier. Even when the lighting is turned off after get off work, the rectifier is still working in the charging state, so that the battery pack is always full State of combat readiness. When the city power suddenly stops in an emergency, the inverter will automatically start the inverter circuit, convert the low-voltage power of the battery pack into high-voltage power, and drive the light source to continue lighting.

Emergency lighting installation specifications:
1. I believe that when shopping, you will find that no matter how many luxurious and fashionable streets, there is an emergency light on the wall. In fact, this is installed in accordance with the regulations of the fire department. Although it looks not very pleasing, it is It is the backing of safety. At the same time, for this kind of emergency light, not only must the quality meet a certain standard, but also the inspection standard of the relevant department.
2. In most occasions, the installation height of this type of lamp is 2.3m. In fact, there is a certain basis. Like our ordinary residence, the height of each floor is about 2.8m, and the height of commercial places will be higher. Some, so installing the emergency light at this height is enough to achieve the lighting effect, and it is also more convenient for maintenance.
3. For some special places, the product installation height also has other requirements, such as stairwells or corners, these dangerous areas that are prone to crowding and trampling, in an emergency escape, it is likely to be more serious because of being unable to see clearly. Therefore, emergency lights should be installed close to the ground in these places, and the height should not exceed one meter.
4. It is found in daily supervision and inspection that it is common that emergency lighting fixtures cannot be used normally due to incorrect wiring. All emergency lighting fixtures are directly set up with dedicated lines, and no switches are set in the middle. Two-wire and three-wire emergency lamps can be integrated-on a dedicated power supply. The setting of each dedicated power supply shall be combined with the corresponding fire protection regulations. If the emergency power supply rotates separately from the lamp, the electrical connection should be made of high-temperature-resistant wire to meet the fire protection requirements.
5. Generally installed above the door frame of the exit door of the evacuation passage, on the walls of corridors and safety exit walkways, at a height of about 2 meters or more from the ground; in large electronic markets, shopping centers and other places, double-head emergency lights are directly wall-mounted Above the pillar.
6. In a fire situation, there is less smoke and more oxygen close to the ground, and the instinctive response of people to evacuate is to bend over or crawl forward, so local high-illuminance lighting is more effective than the uniform illuminance brought by high-level installation. Therefore, low-level installation should be promoted, that is, emergency lighting for evacuation should be provided close to the ground or at ground level.
