Fabricantes de luz de baño IP44 le llevan a entender cómo elegir la iluminación del baño
1. Distinguish product grades. The IP44 Bathroom light manufacturer tells you that bathroom lamps are distinguished by the IP code in the product quality certification. The IP protection level is composed of two numbers, and one number indicates the level of the lamp against dust and foreign objects. The second number indicates the degree of airtightness of the lamp against moisture and water intrusion. The larger the number, the higher the protection level.

Los fabricantes de luces de baño IP44 lo llevan a entender cómo limpiar las luces del baño
The IP44 Bathroom light manufacturer tells you that the bathroom light bulb has been used for a long time, and there will be a lot of dust on the surface, so it is necessary to clean it regularly. How do you clean bathroom light bulbs? The following paragraphs describe specific methods and procedures for cleaning bathrooms, etc.

First, the main points of bathroom lamp purchase. 1. Bathroom environment. IP44 Bathroom light manufacturers tell you that because the bathroom area is generally not large, the bathroom lights you choose should not be too large, and crystal lamps, floor lamps, etc. are not suitable for bathroom use. The bathroom lamp can choose a warm light source, which is not dazzling when bathing and can also give people a warm feeling. Because the water vapor in the bathroom is heavy, the lamps must be waterproof to ensure safety. Generally, ceiling light with a wall light is better.

¿Qué preparativos deben hacerse antes de instalar el sistema de evacuación inteligente?
Generally, there are emergency lighting controllers in many large public places. It is a terminal control system and is generally used for fire fighting. This system is also known as an intelligent evacuation system, which can control emergency lighting and indicate the direction of the lighting, bringing convenience to fire evacuation or personnel evacuation.

Before construction and installation of the emergency lighting and evacuation indication system in the emergency lighting centralized power supply system, the outer packaging of the product should be checked for damage

The emergency lighting centralized power supply is to merge all emergency lighting control emergency start power sources into one system, so that it can be started in time. There are many power supply methods for emergency lighting, including grid independent power supply, diesel generator set power supply, and battery power supply. Generally used for emergency events, for example, it can be linked with a fire alarm in the event of a fire, and it can be used as emergency lighting when the power is out of accident. There are three emergency lighting control methods, namely, emergency lighting fixtures are turned on 24 hours a day, emergency lighting fixtures are all powered by their own batteries, and emergency lighting fixtures can be used simultaneously with other lamps. The advantages of centralized power supply for emergency lighting: 1. Safe voltage power supply-The fire emergency lighting uses DC24V power supply. The DC24V power supply system is called "uncharged system". Compared with the traditional emergency lighting lamps using 220V power supply, the safety is greatly improved. 2. Low accident risk and low maintenance cost-the battery central station type power supply system has the risk of complete power failure. The battery maintenance and replacement of the self-powered fire emergency lighting is inconvenient, and the operating cost is high. The advantages of decentralized centralized power supply are very obvious . 3. Realized the transition from "nearest evacuation" to "safe evacuation"-it can be linked with fire alarm to quickly and accurately obtain the location information of the fire point. At the same time, the computer automatically generates the evacuation plan and controls the fire emergency signs The lights indicate the best evacuation route.

Iluminación de emergencia fuente de alimentación centralizada adecuada para lugares de instalación
In actual construction projects, the choice of emergency lighting centralized power supply should be based on the number of floors, scale, complexity of the building, the number of people staying and moving in the building, the characteristics of the production and use of the building, the degree of fire hazard, and the building’s The importance and other factors, as well as other emergency power supply settings, etc., select the appropriate emergency lighting centralized power supply. The combined power supply mode has the advantages of more than two power supply modes, and the shortcomings of one side can be complementary. Although the investment is large, due to its high reliability, it is still widely used in high-rise buildings and some particularly important large buildings. When the normal lighting power supply fails, an emergency lighting part is set to ensure the continuation of normal activities. Generally, backup lighting should be provided in the following areas: 1. After power failure, failure to operate or dispose of places that may cause explosions, fires, and poisoning accidents, such as hydrogen production, paint making, chemical industry, petroleum, plastics, celluloid and its products production, explosive production, solvent production, etc. 2. Failure to operate or handle in time after a power failure will cause confusion in the production process or damage to the valuable parts processed. Such as some processes in the chemical, petroleum and other industries, steelmaking furnaces, metal melting and casting, heat treatment, precision processing workshops in metallurgy and aerospace industries. 3. Turning off the lights will cause major political impact or severe economic losses. Such as important communication centers, radio stations, television stations, power plants and central substations, control centers, *and international conference centers, important hotels, international terminals, transportation hubs, and important power stations (heating, gas, and oil) ), water supply facilities, etc. 4. Turning off the light will hinder the fire rescue work. Such as fire control room, emergency generator room, broadcasting machine room, power distribution room, etc. 5. Important underground buildings will be unable to work and move due to interruption of lighting. Such as subway stations, underground hospitals, large and medium-sized underground shopping malls, underground hotels, underground restaurants, underground garages and underground entertainment venues. 6. When the lights are off, cash and valuables will be stolen. Such as the valuables sales area, cash register and bank cash register of large and medium-sized shopping malls.

Las características del indicador inteligente de evacuación
1. When a fire occurs, the system can change the direction according to the location of the fire point, and guide the masses to evacuate away from the fire point. ①When the fire point is close to the exit of the corridor, the evacuation exits on the floors above the exit must be displayed closed, so that the crowd can avoid danger and evacuate to the exit near the fire point on the fire floor. ② People on floors below the fire point can be evacuated to any exit to achieve the purpose of evacuation as soon as possible. 2. The fire scene is full of smoke, and the traditional evacuation indicator will be unclear at this time; this intelligent system can use voice, strobe and other function prompts when approaching or reaching the exit to warn the evacuees, avoid missing the exit, and ensure rapid evacuation. 3. The intelligent system can perform self-inspection and patrol inspection of various indicator lights and emergency lighting fixtures online in real time at ordinary times. Alarm, display, and record the information (lamp number, communication address, fault status) of the malfunctioning lamp.
