24V explosion proof light: the core of industrial safety lighting solutions and application analysis

First, why 24V explosion proof light into a high-risk environment preferred lighting solutions?

In petrochemical, mining, natural gas and other flammable and explosive places, the safety and stability of lighting equipment is directly related to the lives of people, asset safety. Compared with the traditional 220V high-voltage lighting system, 24V explosion proof light with its low-voltage power supply characteristics, significantly reducing the risk of explosion caused by sparks. According to the international explosion proof standard IEC 60079, circuits below 24V can be categorized as “intrinsically safe” [Intrinsic Safety] under specific conditions, which makes it an inevitable choice for lighting upgrades in high-risk areas.

Second, 24V explosion proof light core technology advantages analysis

1. Low voltage safety protection mechanism

24V explosion proof light using DC or safety isolation AC power supply, even if the line is accidentally broken, the voltage value is much lower than the minimum ignition energy of combustible gases [MIE], from the root to eliminate the risk of ignition of electric sparks. With IP66/67 protection level housing, it can resist dust, humidity and chemical corrosion.

2. High-efficiency LED light source technology

Modern 24V explosion proof lights and lanterns are generally equipped with high-efficiency LED modules, compared with the traditional explosion proof metal halide lights to save energy by more than 50%. To a brand, for example, its 120W model can implement 20,000 lumens output, and hold to help -40 ℃ ~ +55 ℃ wide temperature range of stable operation.

3. Modular explosion proof structure design

Approved explosion proof Enclosure and safety-enhanced terminal design, to ensure that the internal component failure flame can be effectively blocked. Complies with ATEX, UL 844 and other international certification standards.

Third. Typical application scenarios and industry cases of 24V explosion proof lights

1. Petrochemical tank area lighting

In the refinery tank area, 24V explosion proof searchlight can supply more than 30 meters projection distance, with antihydrogen sulfide corrosion coating, to meet the requirements of API RP 500 explosion proof zoning.

2. underground coal mine tunnel lighting

Adopting intrinsically safe 24V explosion proof mining lights, approved by MA/KA dual certification, can still operate safely in the shaft with excessive methane concentration, avoiding the risk of heat buildup of traditional battery lights.

3. Food processing explosion proof cold storage

For ethanol cleaning environment, the choice of stainless steel shell 24V explosion proof LED lights, while meeting the explosion proof and food-grade health guidelines [FDA 21 CFR], light uniformity of 0.8 or more.

Fourth, the purchase of 24V explosion proof lights 5 fundamental indicators

1. explosion proof certification mark: confirm that the product has the corresponding regional explosion proof mark [such as China Ex d Ⅱ C T6, North America Class I Div 1

2. light source life and lumen maintenance rate: preferred L70>50,000 hours LED programs

3. Circuit protection function: short circuit, over-voltage and reverse connection protection module should be integrated.

4. Installation compatibility: support for boom, wall, flange and other fixing methods

5. Convenience of maintenance: the use of quick-open cover design, shorten the power outage maintenance time

Maintenance convenience: the use of quick-open cover design, shorten the maintenance time of power outages

Al cincilea. 24V explosion proof light specificații privind instalarea și întreținerea

– Wiring requirements: the use of flame retardant cable [such as CYBR type], and non-explosion proof line maintenance of more than 0.5 meters apart.

– Grounding care: lights and lanterns shell must be approved ≥ 4mm ² wire into an independent grounding network, grounding resistance <4Ω

– Regular testing: quarterly illumination test and seal aging checks to ensure that the explosion proof performance does not degrade

Sixth, the future momentum: intelligent 24V explosion proof light system

Along with the popularization of IIoT technology, a new generation of 24V explosion proof lights are being integrated with the following innovative features:

– Equipped with LORA wireless dimming module, remote brightness control

– Built-in temperature/gas sensor, automatically triggering emergency lighting mode

– Approve EtherCAT bus to link with DCS system to generate lighting energy consumption analysis report.
