12V explosion proof light: industrial high-risk environment lighting safety guide

12V explosion proof light in the oil platform application scenarios: Ex certification 12V explosion proof light in the offshore drilling platform actual installation cases

First, 12V explosion proof lights why become the new global industrial safety guidelines?

In the latest revision of IEC 60079-14 clearly advocate: 12V explosion proof lights in Class IIC explosive environment with significant safety advantages. Compared with traditional high-voltage lighting systems, its core advantages are reflected in:

Voltage safety threshold: 12V DC breakdown energy is only 2.7% of the 220V system, fundamentally eliminating the risk of ignition of electric sparks energy efficiency revolution: the use of third-generation COB LED module, luminous efficacy up to 165lm / W, energy-saving than the traditional explosion proof lights 68% of the Intelligent Internet of Things: integrated 485 communication interface, with the help of real-time monitoring of each lamps and lanterns: operating temperature 〔-40 ° C ~ +85 ° C〕 current fluctuation 〔±5% accuracy〕 failure warning 〔±5% accuracy〕. ±5% accuracy] fault warning [4 hours in advance warning].

Industry data: Global 12V explosion proof light market size of 3.7 billion U.S. dollars in 2022, a compound annual growth rate of 11.2% [Source: Grand View Research].

Second, 12V explosion proof light 6 core technology analysis

1. Military-grade explosion-proof structural design

Shell using high-pressure cast aluminum process [ADC12 material], approved by the 7 impact test:

1.5 meters free fall impact IK10 mechanical impact protection 35MPa static water pressure test

2. Intelligent thermal management system

12V explosion proof light cooling structure: patented fin cooling structure to implement the surface area increased by 300%.

3. Intrinsically safe power supply module

Input voltage range: 9-36VDC output ripple <50mV short circuit / overload / reverse connection triple care

4. Intelligent constant current drive technology

Military grade IC chip, voltage fluctuations of ± 20% still maintain the brightness stability, to solve the traditional explosion proof light strobe problem.

5. Nano-scale heat dissipation structure

Unique fin type heat dissipation design makes the surface temperature of lamps and lanterns always lower than 65℃, 40℃ lower than conventional products.

6. Three-proof coating process

Approved 2000 hours of salt spray test, protection level up to IP68, suitable for offshore drilling platforms and other extreme environments.

Third, 12V explosion proof light selection of the golden rule [with a comparison table]

Base model parameter
Protection level IP66
Operating temperature -20℃~+50℃
Explosion-proof certification ATEX II 2G
Average life expectancy is 50,000 hours

Industrial reinforcement parameters
Protection level IP68
Operating temperature -40℃~+70℃
Explosion-proof certification IECEx EPL Gb
The average life span is 80,000 hours

Selection proposition:

Chemical workshop: choose the model with acid mist anticorrosion coating offshore platform: need to meet the EN 61547 anti-salt spray 2000h guidelines mine tunnel: configure 120 ° wide-angle lens to enhance the irradiation range

Fourth, 12V explosion proof light combat case library

Case 1: Sinopec oil storage base renovation project

Replace the traditional 400W mercury lamp for 120W 12V explosion proof light annual power consumption from 3.58 million degrees to 970,000 degrees maintenance cycle extended from 3 months to 5 years

Case 2: Norwegian offshore LNG platform

The use of intrinsically safe 12VDC system approved by DNV GL strict certification at -30 ℃ extreme cold environment start time <0.5 seconds

Case 3: Petroleum storage tank area lighting renovation

After adopting 1200 sets of 12V explosion proof lights in a refining base of PetroChina, the annual maintenance cost has been reduced by 62%, and the light uniformity has been improved to more than 0.8.

Case 4: food-grade ethanol production workshop

Explosion-proof grade up to Ex de IIC T4LED lamps and lanterns, the perfect solution to the traditional metal halide lamp mercury pollution problems.

V. 12V explosion proof light maintenance technology white paper

1. Daily testing procedures

The use of FLIR thermal imaging camera monitoring: lamp body temperature > 85 ℃ immediately shut down monthly testing insulation resistance: > 100MΩ [500V megohmmeter] Quarterly cleaning of the cooling channel: the use of 0.15MPa compressed air

2. fundamental parts replacement cycle

3. Emergency troubleshooting

Phenomenon: Frequent flickering of lamps

Processing steps:

Cut off the power and wait for 10 minutes to discharge detection of input voltage [9-36VDC] using a multimeter to measure the output of the driver board [11.8-12.2V] to replace the faulty driver module [ATEX certified parts].

Six. 12V explosion proof light FAQ authoritative answer

Q1：Can 12V explosion proof lights directly replace the original 220V lamps?

A: The need to transform the power supply system for DC power supply, advocating the use of PSE certified AC/DC converter [such as Meanwell DR-120 series].

Q2：Special requirements in the hydrogen environment?

A: IIB+H2 certified models must be used, and the installation height from the ground <0.5 meters [hydrogen density < air].

Q3：How to approve the lamps and lanterns code to identify the authenticity?

A: Regular product explosion-proof marking should contain: Ex db IIC T6 Gb/Ex tb IIIC T85℃ Db
