Ex outdoor lamp led in the mine lighting fundamental role and application analysis

Accompanied by the mining safety standards continue to improve, explosion-proof outdoor lamps because of its high efficiency, safety, durability characteristics, has become the core equipment for mining lighting.

In this paper, from the technical advantages, application scenarios, industry standards and maintenance points and other perspectives, systematic analysis of Ex outdoor lamp led in the mine in the role of the fundamental, to help enterprises to implement the double intention of safety and efficiency.

First, Ex outdoor lamp led core advantages

1. Intrinsically safe explosion-proof design

Ex outdoor lamp led using high-strength aluminium alloy shell and sealing process, can effectively isolate the flammable gas [such as methane, coal dust] and the internal circuit contact, to avoid spark triggering an explosion.

For example, Amasly explosion-proof LED lamps approve the sound wave welding process to implement seamless connection between the lampshade and the lamp shell, to ensure stable operation in explosive gas environments [such as IIA, IIB, IIC hazardous areas].

2. Energy efficient and long life

LED light source energy consumption is only 30% -50% of the traditional lamps and lanterns, and life expectancy of up to 50,000 hours or more, significantly reducing the mine power costs and maintenance frequency.

Mining explosion-proof LED flood lights to help wide voltage input [80V-260V], even in the voltage fluctuations in the underground can also maintain the brightness stability.

3. Adapt to extreme environments

Ex outdoor lamp led have IP66 protection level and WF2 anticorrosive ability, which can resist high humidity, dust and corrosive gas erosion in the mine.

Amasly explosion-proof floodlight adopts toughened borosilicate glass cover, impact resistance and high light transmittance, to protect the lighting effect in harsh environments.

Second, Ex outdoor lamp led mining application scene

1. Mining roadways and excavation workings

Mining explosion-proof LED tunnel light with wide-angle lighting and long-distance projection [up to 100 m], for underground tunnel, transport belt and digging operations to supply uniform light, reduce the visual blind spot, enhance operational safety.

2. Gas and Dust High Risk Area

In coal mine gas concentration areas or petrochemical plants, explosion-proof lighting explosion-proof design can avoid spark ignition of dangerous gases.

For example, Amasly explosion-proof headlamps are approved with sealed construction and explosion-proof certification for explosive dust environments.

3. Equipment maintenance and emergency lighting

Portable explosion-proof headlamps with the help of multi-mode adjustment [strong light, low light, flashing], to meet the equipment maintenance, night inspection and emergency lighting needs of sudden accidents.

Third. Technological innovation and industry standards

1. Intelligent heat dissipation and cleaning system

The latest mine lighting fixtures integrate heat dissipation fan and automatic cleaning module, approving the telescopic rod to adjust the position of the cleaning bar, and regularly removing the dust accumulated on the outer wall of the lampshade to ensure the light transmittance.

This design significantly extends the life of the lamp and reduces the cost of manual maintenance.

2. Compliance with international safety certification

Explosion-proof lamps need to meet GB/T 3836.1-2021 [explosive gas environment equipment guidelines] and MT221-2005 [coal mine explosion-proof lamps and lanterns guidelines], to ensure that from the material to the circuit design of full compliance.

Fourth. Application and Maintenance Precautions

1. Installation: The lamps should be kept away from the sparking area and fixed in a stable bracket to avoid vibration leading to sealing failure.

2. Regular Inspection: Clean the surface of the lampshade every month and check whether the heat dissipation holes and filters are blocked to ensure the heat dissipation efficiency.

3. Prohibit electric operation: cut off the power supply when repairing or replacing to prevent electric shock or accidental ignition.

Fifth. Future momentum: intelligent and multi-functional integration

Along with the development of Internet of Things technology, Ex outdoor lamp led will be integrated with remote control, environmental monitoring [such as gas concentration detection] and other functions, the implementation of ‘lighting + safety warning’ integration, to promote the upgrade of mine intelligence.

FAQ: Ex outdoor lamp led common problems

Q1：How to choose the explosion-proof grade of explosion-proof lamps and lanterns?

A1: According to the classification of the mining environment [such as the type of gas, hazardous area level] to choose the corresponding certification [such as Ex dblMb], you can refer to GB/T 3836 guidelines.

Q2：What is the maintenance cycle of the lamps?

A2：It is recommended to carry out a comprehensive inspection every 3 months, covering cleaning, heat dissipation test and circuit stability assessment.

Q3：Is LED explosion-proof lamp suitable for high humidity mine?

A3：Yes, IP66 protection grade can effectively prevent water vapour intrusion, suitable for humidity over 90% environment.
