Explosion-proof luminaires are hazardous locations for the presence of flammable gases and dusts. In these applications, the luminaires are used to prevent arcing, sparks and high temperatures inside the lamps from igniting flammable gases and dusts in the surrounding environment. Purpose, there are many types of such lamps, so explosion-proof lamps are divided into many types according to their functions and practical places. Today, Xiaobian will introduce you to the installation and maintenance of LED explosion-proof lamps and the price of LED explosion-proof lamps .
LED explosion-proof lamp classification
LED explosion-proof lamp classification
Explosion-proof lighting has been used in the market this year, especially in the kitchen and bathroom. Then according to the level and category of explosion-proof lamps, we divide them into the following levels:
1. Explosion-proof lamps, explosion-proof categories, levels and temperature groups are subject to national standards.
2. According to the explosion-proof type, there are 5 main types of explosion-proof type, increased safety type, positive pressure type, non-sparking type and dust explosion-proof type. It can also be combined with other explosion-proof type and various types of explosion-proof type. Special type.
3. According to the type of protection against electric shock, it can be divided into I, II and III. The anti-shock protection is to prevent the parts of the explosion-proof lamp housing from being easily touched, so that the human body is exposed to electric shock or conductors of different potentials to generate an electric spark to ignite the explosive mixture. AI class - On the basis of basic insulation, connect the electrically conductive parts that are accessible during normal operation without electricity to the protective earthing conductors in the fixed line. Class BII - Use double or reinforced insulation as a safety measure without grounding protection. Class CIII - Use a safe voltage with an effective value of no more than 50v, and no higher than this voltage value will be generated. Class D0 - rely solely on basic insulation as a safety measure. Most of the explosion-proof lamps are protected against electric shock, and only a few are Class II and Class III lamps. For example: all-plastic explosion-proof lamps, explosion-proof flashlights.
4. According to the degree of protection of the outer casing: in order to protect dust, solid foreign matter and water from entering the lamp cavity, touching or accumulating on the live parts, there is a danger of flashover, short circuit or damage to electrical insulation. Protect the role of electrical insulation. Use the characteristic letter "IP" followed by two numbers to characterize the degree of protection of the enclosure. The first number indicates the ability to protect against humans, solid foreign objects or dust. Divided into 0-6.
Explosion-proof luminaires are sealed luminaires with a dust-proof capacity of at least 4 or more. The second number indicates the protection against water and is classified into 0-8.
5. Classification of support surface materials according to luminaire design: Indoor explosion-proof luminaires may be installed on many surfaces of common flammable materials, such as wooden walls and ceilings. They do not allow the temperature of the installation surface of explosion-proof luminaires to exceed safe values. According to whether the explosion-proof lamps can be directly installed on the surface of ordinary combustible materials, they can be classified into two categories. One type is a luminaire that is only suitable for installation on a non-combustible surface. The other type is a luminaire suitable for direct mounting on the surface of ordinary combustible materials, with marking symbols.
6. According to the installation and use form can be divided into fixed, portable, portable.

LED explosion-proof lamp performance and characteristics
The LED explosion-proof lamp is mainly composed of two parts, and the lamp housing and LED are integrated. The outer casing is generally formed by die casting of aluminum alloy. LEDs are generally used in international brands.
1. LED explosion-proof lamps are mainly suitable for the application of fixed lighting for petroleum, petrochemical, offshore oil platforms, electric power, metallurgy, railways, steel, ships, military, chemical, stadiums and various indoor and outdoor flammable and explosive places.
2. The LED explosion-proof lamp housing is formed by high-pressure aluminum alloy casting, and the surface is sprayed with high-pressure electrostatic spray to effectively improve the heat dissipation performance of the housing.
3, using high-brightness LED light source, with high efficiency constant current driving power supply, saving 60% than gas discharge lamp; LED components are all sealed, waterproof and dustproof, no internal cleaning and maintenance; circuit substrate low thermal resistance, specially designed Module circuit, each unit failure will not affect the normal operation of the remaining components.
4. The circuit board is closely attached to the aluminum alloy casing, which can instantly convert the point heat source into a surface heat source, and the heat dissipation area is multiplied, which facilitates the rapid dispersion of heat and improves the heat dissipation efficiency; the surface of the casing has a gas flow dispersion groove, which is carried away by the air flow. Heat; heat sink fin density is high, greatly improving the heat dissipation area, fully ensuring the heat dissipation requirements of the LED, and the service life is longer.
5, LED explosion-proof lamp can be installed with wall-mounted rotation angle adjustable, cable wiring, ceiling-mounted, embedded installation can be cable or steel pipe wiring.

Explosion-proof lamp luminaire price - by form
The so-called form is actually the way to carry out effective riot prevention. Therefore, the anti-riot form of the explosion-proof lamp is the same, so the working principle and price of the explosion-proof lamp are also different. So how much is the explosion-proof lamp? According to the situation, the price of the explosion-proof lamp will also become different. All in all, knowing how to understand and understand the explosion-proof lamp, you can effectively choose the explosion-proof lamp. According to Xiaobian, the price of the explosion-proof lamp is about 100 yuan to 280. This price is for reference only!
Explosion-proof lamp luminaire price - by type
There are actually only one type of explosion-proof lamps, which are different according to the environment used, and the form is different. Therefore, there are no fewer than ten kinds of explosion-proof lamps according to the type. So how much is a set of explosion-proof lamps? Prices are actually related to different types. Then, according to the type, how much is the explosion-proof lamp? In fact, this is not necessarily the case, according to the different manufacturers' production and production processes, the wholesale price will be different. Therefore, the final sale price will have a considerable deviation, how much is the explosion-proof lamp? About 100 yuan or more! This price is for reference only!
Explosion-proof lamp luminaire price - by grade
Since it is an explosion-proof luminaire, the level of riot prevention should be in line with the national requirements. For some places, if the requirements for riot prevention are not so high, you can generally choose a riot level that is weaker, so the price will be more affordable. Explosion-proof lamps are much more expensive if you choose to have a higher level of riot protection. How much is a set of explosion-proof lamps? All in all, according to the level of riot prevention, how many sets of explosion-proof lamps of different levels, it must be the answer that everyone wants to know! Almost a set of about 200 yuan, this price is for reference only!
Explosion-proof lamp price - by light source
How much is the explosion-proof lamp? The most important factor in determining the price is the power of the light source and the wattage. Through the unique light source design, the illumination angle can be precisely controlled to avoid the source being too dark or too strong, and the source pollution can be avoided.
Explosion-proof light sources include incandescent lamps, fluorescent lamps, hybrid light sources, and mercury lamps. The effects of these different light sources are also different. Therefore, there will be some deviation in the price, then according to the light source, how much is the explosion-proof lamp? It is almost 100 yuan to 400 yuan. This price is for reference only!
Explosion-proof lamp price - by material
Whether it is according to the power of the light source, or according to the different levels and forms of the explosion-proof lamp, these are the factors that affect the price, and the amount of the explosion-proof lamp is determined to belong to the material. So how much is the explosion-proof lamp of different materials? Depending on the material, and the advantages and characteristics of the material, the price of the explosion-proof lamp is not the same. However, according to the overall situation, the price of explosion-proof lamps is not very expensive, and its quality and price are definitely proportional. In addition, there are some accessories for explosion-proof lamps, such as chips and drive power supplies.
