Explosion proof bulbs in the pharmaceutical plant lighting in the core applications and safety selection guide

Explosion proof bulbs to analyze how to ensure the safe and efficient operation of pharmaceutical production

First, the core challenges of the pharmaceutical plant lighting environment: why must choose Explosion proof bulbs?

Pharmaceutical factories as a high-precision, high-security requirements of industrial premises, the production environment is often faced with the following risks, the lighting equipment to put forward stringent requirements:

Explosive gases and dust risk: raw materials workshop, solvent storage areas and other areas prone to the accumulation of ethanol, acetone and other volatile substances, or dust particles, ordinary lamps and lanterns sparks or high temperatures probably triggered an explosion.

Chemical corrosion and humid environment: pharmaceutical clean area needs frequent disinfection, acid and alkali detergents, high humidity environment to accelerate the aging of lamps and lanterns, resulting in leakage or short circuit.

Cleanliness and long-term maintenance needs: GMP guidelines require that lamps and lanterns do not accumulate dust, easy to clean, and need a low failure rate to reduce the risk of production interruption.

Explosion proof bulbs are approved for the following designs to meet the challenges:

Explosion-proof construction: Aluminum die-cast housing with tempered glass cover, internal circuitry is completely sealed to isolate flame spread even if there is an internal explosion, meeting high level explosion-proof guidelines such as Exd II CT6.

Corrosion resistance and high protection level: surface electrostatic spraying process, IP66/IP67 protection level, resisting disinfectant erosion and dust infiltration.

Energy efficient and long life: LED light source luminous efficacy of 130lm/W or more, life expectancy of more than 50,000 hours, reducing the frequency of replacement, reducing the risk of contamination in the clean area.

Second, explosion-proof lights in the pharmaceutical plant core application scenarios and selection points

1 raw materials workshop and solvent storage area

Risk characteristics: ethanol, methanol and other flammable and explosive gas environment.

Explosion proof bulbs selection: to meet the Exd II CT4 or more explosion-proof grade, the surface temperature of the lamps and lanterns is less than 135 ℃ [T4 group], recommended 80W-150W LED explosion-proof floodlights, equipped with batwing light distribution to implement uniform lighting.

2. Clean area and sterile workshop

Special needs: dustproof, easy to clean, no strobe light source.

Solution: recessed LED explosion-proof panel light, protection level IP66, the surface is made of stainless steel, with the help of alcohol wiping; color temperature selection 5000K white light, to avoid the color difference affects the quality inspection.

3. Warehouse and packaging area

Functional requirements: wide coverage, anti-vibration.

Recommended configuration: 100W-200W explosion-proof industrial and mining lamps, installation height of 5-8 meters, paired symmetrical light distribution, illuminance of more than 300lux, in line with EN 12464 guidelines.

4. Laboratory and R&D center

Intelligent control requirements: dimming, emergency lighting.

Technology integration: explosion-proof lights with microwave sensors or PLC system, automatic switching emergency mode after the main power failure, endurance time ≥ 90 minutes.

Third, the pharmaceutical plant explosion-proof light selection of the four fundamental indicators

1. Explosion-proof grade matching: gas environment: IIA / IIB / IIC class [such as ethanol for the IIB class]; temperature group T1-T6 [solvent area needs to be more than T4].

2. Light source performance: LED luminous efficiency > 110lm / W, color rendering index Ra> 80, to ensure the accuracy of drug color identification.

3. Protection and material: shell material: aluminum alloy die-casting [lightweight] or 316 stainless steel [high corrosion area]; anti-corrosion grade WF2.

4. Installation and maintenance convenience: support ceiling type, boom type and other methods of installation; modular design, light source and power chamber independent, maintenance without power failure.

Fourth, Explosion proof bulbs installation specifications and maintenance strategy

1. Specialized installation points

The cable introduction port is sealed with explosion-proof glands to avoid moisture intrusion. Lamps and lanterns are spaced according to 4-6 meters layout, to avoid the shadow of the blind zone.

2. Periodic maintenance program

Monthly inspection: Clean the surface of the lampshade to prevent the accumulation of dust affecting the light transmittance. Quarterly Inspection: Measure insulation resistance >2MΩ with megohmmeter to ensure circuit safety.

3. Intelligent operation and maintenance momentum

Approval of the Internet of Things platform for real-time monitoring of lamps and lanterns voltage, temperature, abnormal data automatic warning to reduce sudden failure.

Fifth. Future momentum: intelligent and green energy-driven explosion-proof lights upgrade

Digital twin technology: approved 3D modeling simulation of the lighting system, AI predicts the life of the equipment, improve spare parts management.

New energy power supply: wind and solar complementary system with DC24V low-voltage Explosion proof bulbs, reduce cable costs, hold to help pharmaceutical companies in the carbon, intention.

LiFi optical communication: alternative to WiFi in the clean area, Explosion proof bulbs integrated LiFi module, the implementation of data transmission with zero electromagnetic interference.

Conclusion

Pharmaceutical plant lighting safety is related to personnel life and product quality, explosion-proof lights with its explosion-proof, corrosion-resistant, long life and other characteristics, into a fundamental equipment to protect production.
