Fire emergency ceiling lamp, as an essential safety device in public buildings, plays a crucial role in ensuring the safety of people's lives and property during emergencies. This article will introduce the industry of fire emergency ceiling lamps, including their classification, working principle, selection, installation, and maintenance, aiming to provide a comprehensive understanding of this product.

Classification of Fire Emergency Ceiling Lamps

Fire emergency ceiling lamps can be divided into several types according to their application scenarios and working principles. The main types include: 1. Fire emergency lighting lamps: These lamps are designed to provide lighting for people to evacuate during emergencies, ensuring their safety in darkness. They can be divided into constant current lamps and constant voltage lamps according to the power supply mode. 2. Fire emergency indicator lamps: These lamps are used to indicate the location of fire emergencies, helping people to quickly identify the fire source and take appropriate measures. They can be divided into LED indicator lamps and neon indicator lamps according to the light source. 3. Fire emergency smoke evacuation lamps: These lamps are used to guide people to safety during emergencies, especially in places with high smoke density. They can be divided into smoke evacuation lamps with and without sound according to their functions. 4. Fire emergency emergency power supply lamps: These lamps are used to supply power to emergency equipment and systems during emergencies, ensuring the normal operation of fire protection systems. They can be divided into battery-powered lamps and emergency power supply lamps according to the power supply mode.

Working Principle of Fire Emergency Ceiling Lamps

The working principle of fire emergency ceiling lamps is mainly based on the following aspects: 1. Power supply: Fire emergency ceiling lamps can be powered by normal power supply or emergency power supply. In the event of a power failure, the emergency power supply will automatically start to ensure the normal operation of the lamps. 2. Control circuit: The control circuit of fire emergency ceiling lamps is mainly composed of sensors, control modules, and executive devices. When a fire emergency occurs, the sensors will detect the smoke, temperature, and other signals, and send them to the control module for processing. After processing, the control module will send control signals to the executive devices to make corresponding actions. 3. Lighting mode: Fire emergency ceiling lamps have two lighting modes: normal lighting and emergency lighting. In normal lighting mode, the lamps work as ordinary lighting equipment. In emergency lighting mode, the lamps will automatically switch to emergency lighting mode and provide lighting for people to evacuate. 4. Signal indication: Fire emergency ceiling lamps can send signal indication to the central control system through communication lines or wireless transmission, so that the central control system can monitor the working status of the lamps in real time.

Selection of Fire Emergency Ceiling Lamps

When selecting fire emergency ceiling lamps, the following factors should be considered: 1. Application scenario: According to the application scenario of the fire emergency ceiling lamps, select the appropriate type and specification of the lamps. 2. Power supply mode: According to the power supply mode of the building, select the appropriate power supply mode of the lamps. 3. Light source: According to the requirements of the lighting effect, select the appropriate light source of the lamps. 4. Brand and quality: Choose well-known brands with high quality and stable performance. 5. Price: Compare the price of different products and choose the most cost-effective product.

Installation of Fire Emergency Ceiling Lamps
