LED explosion-proof light principle LED explosion-proof light is a kind of explosion-proof light, its principle is the same as explosion-proof light, except that the light source is LED light source, which means to prevent ignition of surrounding explosive mixtures such as explosive gas environment, explosive dust environment, gas gas, etc. The lamps of various specific measures.
So how does LED explosion-proof light achieve explosion-proof? How does it achieve explosion-proof requirements?
The principle of the LED explosion-proof lamp is the same as that of the explosion-proof lamp. The principle is based on the explosion-proof concept and fire type of the European standard EN13463-1:2002 "Non-electrical equipment for explosive atmospheres Part 1: basic methods and requirements". Flameproof type is to take measures to allow An explosion-proof type that explodes inside and prevents flame propagation is the most commonly used explosion-proof type. Since the explosion-proof type lamp housing is generally made of a metal material, the heat dissipation is good, the strength of the housing is high and the durability is good, and it is very popular with users. Moreover, many increased safety explosion-proof lighting components, such as lamp holders, interlock switches, etc., are also flameproof structures. An electrical device with a flameproof enclosure is called a flameproof electrical device. If the explosive gas mixture enters the flameproof enclosure and is ignited, the flameproof enclosure can withstand the explosive pressure of the internal explosive gas mixture and prevent the internal explosion from propagating to the explosive mixture around the enclosure. This is a kind of clearance explosion-proof principle, that is, a structure designed by using the metal gap to prevent the propagation of the explosion flame and cool down the temperature of the explosion product, achieve flame extinction and temperature reduction, and suppress the expansion of the explosion principle.
Explosion-proof lamp explosion-proof structure type, according to the regional level and scope of the explosive gas environment is determined, such as within the scope of a region must use flame-proof lamps; 2 fixed lamps in the region can be explosion-proof and increased safety, mobile lighting must Flameproof type. The level or group of explosion-proof lamps selected should not be lower than the explosion mixture level and group in explosion hazardous environments. At the same time, the impact of the environment on explosion-proof lamps should be taken into consideration, and the requirements of various environments such as ambient temperature, air humidity, corrosion, or contaminating substances should be met. According to different environmental requirements, the lighting protection level and the corrosion protection level should be selected. Especially in the presence of corrosive gases in explosive gas atmospheres, it is crucial to select lamps with corresponding corrosion resistance.
In petrochemical enterprises, lighting fixtures in explosion hazardous locations are mainly flameproof. With the increasing use of increased safety electrical equipment in explosion hazardous locations in Zone 2, increased safety and composite lighting fixtures are also being used more and more. The increased safety type luminaire has the advantages of light weight, low price, convenient installation and maintenance, long service life, etc. compared with the flameproof type lamps on the basis of certain explosion-proof performance. The most widely used composite electrical equipment used in petrochemical enterprises is the Zengan-explosion-proof compound type explosion-proof electrical equipment. It is generally composed of three parts: explosion-proof components, increased-safety terminal blocks, and increased safety enclosures. It has both flameproof safety. Performance, but also has the advantage of increased safety.

An
outdoor Wall Sconce is a type of lighting fixture that is designed to
be mounted on the exterior walls of a building. These fixtures are
typically used to provide illumination for outdoor areas such as patios,
porches, and entryways. Outdoor wall sconces come in a variety of
styles, sizes, and finishes to suit different architectural styles and
personal preferences. They can be made from a range of materials
including metal, glass, and plastic, and may feature various types of
bulbs including LED, incandescent, and fluorescent. Some outdoor wall
sconces are equipped with motion sensors or photocells to automatically
turn on and off, providing added convenience and security.
