Key words:
Emergency light is a kind of lighting equipment specially designed to deal with emergencies
An emergency light is a lighting device specially designed to deal with emergencies. As part of emergency equipment, emergency lights have the characteristics of waterproof, fireproof, high brightness and eye-catching to ensure reliable lighting in emergency situations.
Key words:
Fire prevention is essential to protect people
Secondly, the emergency lights have fireproof characteristics. In the event of a disaster, such as a fire, short circuit, etc., fire protection is essential to protect the person. The fire protection design of emergency lights can effectively prevent lamps from causing greater disasters due to fires. Using fireproof materials and fireproof circuit design, emergency lights can work normally in emergency situations without causing a fire, ensuring people's lives and property.
Key words:
The eye-catching characteristics of emergency lights are also very important.
In addition, the eye-catching characteristics of the emergency light is also very important. In an emergency, people need to quickly identify the location of emergency lights in a short time. Emergency lights usually use bright colors, such as red, yellow, etc., and special flashing patterns,
