  • Are you facing the challenge of insufficient safety alerts in hazardous work areas?

    In high-risk environments such as aerospace, semiconductor manufacturing, military industry and petrochemical industry, ensuring employee safety is a significant challenge.

    These workplaces often encounter:

    🔴Insufficient visual alerts -Standard signal lights may not be clearly visible in bright light or smoke, increasing the risk of accidents.

    🔴Insufficient auditory alerts -In high-noise environments, alarm sounds can be easily ignored, failing to effectively warn workers of danger.

    🔴Poor environmental adaptability -Many LED lights, without using explosion-proof enclosures, special seals, and high-temperature resistant materials, have potential risks and are prone to failure or explosion.

    💡The solution is here!

    THT-EX introduces the L1920 LED Explosion-Proof Light Hazardous Location Signal Tower Light, specifically designed for high-risk work areas!

    ✅High-brightness LED light source: Provides five color options, ensuring clear visibility under any lighting conditions.

    ✅Powerful buzzer: With a volume of up to 80 decibels, providing strong auditory warnings even in noisy environments.

    ✅Versatile configurations: Available with or without junction box and buzzer versions to meet your specific needs.

    ✅Rigorous testing: Each unit undergoes 24-hour testing before shipment, including buzzer sound testing, to ensure stable operation.

    ✅Explosion-proof certification: Dustproof, waterproof, and resistant to extreme temperatures, suitable for harsh working environments.

  • Selecting the right Explosion-Proof Lightings to enhance Safety & Visibility in Your Workplace

    As people discuss various humanoid robots powered by AI and GPT, autonomous driving systems, and space races, we have come to understand that the yield rate of semiconductor components is a key factor determining the competitiveness of these products. 

    One of the crucial factors affecting semiconductor yield rates is the use of specialized lighting. 
    We provide the 500nm wavelength specialized lighting required by semiconductor companies worldwide, which is a critical condition for determining yield in the semiconductor process. 
    Our products are certified for general lighting as well as global explosion-proof lightingwith UL (North America), IECEx & ATEX (European Union), CML (Japan), and TS (Taiwan) explosion-proof certifications. 
    Although we are just a small screw in the semiconductor industry, our lighting products determine the quality and stability of your products. 

    Regardless the specific lighting requirements in your workplace, it’s crucial to make the right choice when selecting fixtures. 

    Linear & Tube Industrial Lighting Fixtures are commonly used in various industrial environment, including manufacturing and processing plants, warehouses, and logistics centers. They can provide uniform, wide-area illumination, minimizing shadows, and ensuring adequate visibility.

    In addition, for work environments with dust, hazardous gases and liquids, selecting linear or tube lighting fixtures with explosion-proof protection can ensure that no fire or explosion is triggered during operations, and help to bringing new safety standards to your workplace and production processes.

    Please don't hesitate to reach out if you have any inquiries, and we would be delighted to provide you with a wide range of lighting specifications to meet your specific needs.
    From the technology island of Taiwan, THT-EX always guards you.
