When we encounter a power outage in public places, we can always see that there is a kind of lighting that will be on. This type of lamp is an emergency lighting fixture. It can automatically switch power supply during a power outage and provide people with emergency lighting. It is also our life-saving light when necessary, indicating the correct and safe path for us. So, do you know what kind of emergency lighting products are there? Do emergency lighting fixtures meet national safety standards? So what is the price of emergency lighting ? Here we come together to understand the relevant knowledge of emergency lighting.
Emergency lighting fixtures
Emergency lighting refers to the lighting used in emergency lighting. Emergency lighting fixtures are generally divided into portable emergency lighting, fire emergency lighting, energy-saving emergency lighting, emergency lighting, underwater emergency lighting, rechargeable emergency lighting, solar emergency lighting, and multi-purpose emergency lighting. Many types, which play different important roles in our lives, are an indispensable and important tool for modern security.
Emergency lighting function and composition
Emergency lighting function
Evacuation of emergency lighting and marker lights, collectively referred to as fire emergency lighting, is an important product required in fire safety measures. Normally it should provide lighting like ordinary luminaires. When an emergency such as an earthquake, fire or circuit failure causes a sudden interruption of the power supply, all light sources have stopped working. At this time, it must immediately provide reliable lighting and indicate the evacuation of people. Direction and location of emergency exits to ensure that those stranded in the dark are successfully evacuated. It can be seen that emergency lighting is a light source that maintains lighting and guides evacuation in emergency situations.
composition
The emergency lighting consists of a light source, a light source driver, a rectifier, an inverter, a battery pack, a sign light shell, and the like. Normally, 220V power supply through the light source driver, driving the normal lighting of the light source, while supplementing the battery pack through the rectifier, even if the lighting is off after work, the rectifier is still working in the charging state, so that the battery pack is always full Readiness state. When an emergency occurs and the utility power suddenly stops, the inverter automatically starts the inverter circuit, converting the low-voltage power of the battery pack into high-voltage power, and driving the light source to continue lighting.
Emergency lighting products
I. Fire emergency lighting
Applies to: theaters, shopping malls, hotels, banks, hospitals, apartments, civil air defense projects, underground facilities and other places that require uninterrupted lighting.
Emergency lights can be classified according to work status and function. According to the working status can be divided into 3 categories: 1 continuous emergency lighting. Irrespective of the failure of the normal lighting power supply, lighting can be continuously provided. 2 non-continuous emergency lighting fixtures.
Lighting is only provided when the normal lighting power source fails. 3 composite emergency lighting fixtures. Lamps Emergency lighting fixtures contain more than two light sources, at least one of which provides illumination when a normal lighting power source fails.
By function can be divided into two categories:
1 lighting fixtures. In the event of an accident, necessary lighting can be provided to walkways, exit passages, stairs and potentially dangerous areas.
2 sign lamps. Can clearly indicate the direction of the exit and the passageway. There are words and icons on the light. The brightness of the signage surface is 7~10cd/m2. The stroke thickness of the text is at least 19mm, the height is at least 150mm, the observation distance is 30m, and the light-transmitting text has a contrast with the background. Big contrast.
The emergency lighting consists of a light source, a battery (or battery), a lamp body, and an electrical component. The emergency lighting device using a gas discharge source such as a fluorescent lamp also includes an inverter and its ballast device.
The selection of the battery shall comply with the following provisions: The discharge time shall not be less than 20 minutes when using incandescent lamps, and not less than 30 minutes when using fluorescent lamps; the nickel-cadmium batteries or lead-acid batteries shall be used for emergency lighting fixtures whose installation volume cannot be too large. Long-discharge batteries can be used for long discharge times. Electrical components include DC and AC converters, switching switches to detect circuit performance, and ballast components.

Emergency lighting fixture fire inspection
Fire emergency lighting charge and discharge test pass. Failure of this project will affect the cycle life of the battery and the battery capacity, and may even cause the battery to corrode or explode. Fire emergency lighting fixtures are used for evacuation and fire extinguishing facilities in case of fire. If the over-discharge and over-charge protection circuits fail, it is likely to cause hidden troubles. The reason is that in order to reduce costs and reduce the use of electronic components and circuit boards, some manufacturing companies simplify internal fire emergency lighting fixtures and do not even install over-discharge and over-charge protection circuits.
The main components are qualified. The fuse is installed in the circuit and is an electrical component that ensures the safe operation of the circuit. When the circuit is faulty or abnormal, with the continuous increase of the current, some electronic components in the circuit may be damaged, and the circuit may even burn or cause a fire. If the fuse is correctly placed in the fire emergency lighting fixture circuit, the fuse will blow and cut off the current when the current abnormally rises to a certain condition, thereby functioning to protect the safe operation of the circuit. The clear identification of the current value of the fuse can prevent the user from replacing the fuse and causing unnecessary damage.
Pressure test qualified. The withstand voltage test is an important safety indicator for fire emergency lighting fixtures. If this item fails, it may cause electric shock and endanger personal safety. The reason for the failure was due to insufficient creepage distance and unreasonable design of some products, resulting in breakdown during withstand voltage test. Once the primary circuit and the secondary circuit are punctured, it means that the voltage of the primary circuit (220V) will reach the secondary circuit through the breakdown point, and electric shock or explosion of the battery may occur.
Emergency lighting price
The price of emergency lighting fixtures varies depending on the brand and model. The general emergency lighting price is about 45 yuan, the national standard emergency lighting price is usually about 98 yuan, 250 yuan in the price of emergency lighting is about 88 yuan; general domestic emergency lighting prices only a few yuan or ten A few dollars; and brand emergency lighting prices, such as Panasonic emergency lighting, its price is generally between 150-200 yuan.
Editor's summary: The above is a description of what is the product category of emergency lighting fixtures and emergency lighting fixtures. I hope to be able to help those friends who have this need. If you still want to learn more about the relevant information, please continue to follow our website.
