4 foot explosion proof light fixture in the laboratory lighting in the core role and innovation to get the program

Laboratory as the core place of scientific research and innovation, the lighting system security, stability, functionality requirements are extremely demanding. Especially in the experimental environment involving flammable and explosive chemicals, volatile gases or dust, ordinary lighting equipment may become a major safety hazard.

Explosion-proof tube with its unique design and technical advantages, into the laboratory lighting upgrade program of choice. In this paper, we will analyze the value of 4 foot explosion proof light fixture in the laboratory applications, and supply selection and improvement of ideas.

First, why the laboratory must use 4 foot explosion proof light fixture?

Laboratory environment lurks in a variety of explosive risk sources:

Chemical reagent volatilization: such as ethanol, acetone and other organic solvents in a confined space is easy to form explosive mixtures. Dust aggregation: nanomaterials, metal powders and other combustible dust in the air to reach a certain concentration probably fire explosion. High-voltage equipment interference: some of the experimental instruments may produce sparks or high temperature during operation, increasing the risk of accidental ignition.

4 foot explosion proof light fixture approved by the international explosion-proof certification [such as ATEX, IECEx], the use of explosion-proof cavity and fully sealed structure design to ensure that the lamps and lanterns inside the arc or high temperature and the external hazardous environment is completely isolated from the source to eliminate the potential risk of explosion.

Laboratory lighting system special needs

1. explosion-proof safety level: according to the laboratory hazardous area classification [Zone 1/Zone 2 or Class I Division 1/2] to choose the corresponding explosion-proof grade lamps. 2. chemical resistance: the lamps can be used in a variety of applications.

2. chemical resistance: the lamp housing needs to resist acid and alkali corrosion, to avoid long-term exposure to reagent vapors leading to material aging.

3. accurate light environment: color rendering index [CRI] should be higher than 90, to ensure the accuracy of the experimental color interpretation; color temperature adjustable to adapt to different experimental scenarios.

4. low heat radiation: to avoid the surface temperature of the lamp is too high to affect the precision instruments or heat-sensitive samples.

Second. Amasly explosion-proof lamp core technology breakthroughs

1. Explosion-proof structure and material innovation

4 foot explosion proof light fixture using die-cast aluminum shell and tempered glass lampshade, approved explosion-proof joint surface design to limit the internal explosion pressure in the cavity.

For example, silicone sealing ring is embedded in the threaded interface of the lamp to prevent the infiltration of combustible gases. Some high-end models built-in temperature sensors, real-time monitoring of heat dissipation status and automatic power-off care.

2. Intelligent Light Efficiency Management

High color rendering LED light source: CRI ≥ 95 LED chip can accurately restore the color difference in chromatographic analysis, reducing experimental errors. Strobe-free design: Approved constant-current drive technology to eliminate strobe, care for the eyesight of laboratory personnel and improve the clarity of microscope observation.

Partition dimming function: adjust the light intensity according to the needs of the functional areas of the laboratory [e.g., the biological culture area needs soft and light, the detection area needs high brightness illumination].

3. Efficient heat dissipation and energy saving performance

Laboratory often need 24 hours of continuous lighting, 4 foot explosion proof light fixture using finned heat dissipation structure, with ceramic substrate technology, the operating temperature is controlled below 65 ℃, while the implementation of energy consumption than traditional lamps and lanterns to reduce 70%.

Third, the laboratory explosion-proof lamp selection and installation specifications

Basic selection indicators

1. Explosion-proof grade: Zone 1 area should choose Ex d IIC T4 or above, Zone 2 can choose Ex nA II T3. 2.

2. Protection level: IP65 and above, to prevent water vapor intrusion during cleaning and rinsing.

3. Luminous flux and color temperature: 3000-5000 lm is recommended for routine labs, with a color temperature of 4000K [neutral white]; 6000K [cold white] is recommended for clean rooms or sterile labs to enhance visual clarity.

Installation and maintenance points

1. Wiring specification: use explosion-proof flexible pipe to connect the lamps and lanterns, and install explosion-proof sealing connector at the cable entrance.

2. Layout planning: according to the location of the laboratory table design lighting coverage angle, to avoid shadows to interfere with the operation.

3. Regular testing: quarterly inspection of the aging of the seals, clean the surface of the lamp dust and chemical residues.

Fourth, case: 4 foot explosion proof light fixture in the biopharmaceutical laboratory applications

A national key laboratory in the renovation project after the deployment of LED 4 foot explosion proof light fixture implemented:

Hazardous area lighting system approved ATEX and ISO 17025 dual certification; annual energy costs reduced by 42%, the lamp life extended to 50,000 hours; laboratory personnel due to insufficient illumination resulting in a decrease of 18% in the rate of operational errors.

Fifth, the future momentum: 4 foot explosion proof light fixture and intelligent laboratory integration

Along with the popularity of Internet of Things technology, 4 foot explosion proof lamp fixture are being integrated into the laboratory intelligent management:

Environmental linkage control: approval of gas sensors to monitor the concentration of combustibles, automatically shut down non-explosion-proof equipment and start emergency lighting.

Energy consumption data visualization: real-time statistics on the power consumption of lighting in each area to improve the energy distribution strategy.

Remote troubleshooting: The built-in chip can upload the operation status to the cloud platform, early warning of potential failures.
