Reliability in explosion-proof areas is essential, and glare reduction along with high color rendering improves work efficiency! Compared to our conventional fluorescent fixtures, power consumption is reduced by approximately 55%!

Introducing the new explosion-proof LED light series, the 'LZBA series', designed to meet the high reliability required in explosion-proof areas and suitable for use in explosive hazardous locations Zone 1 and Zone 2! While equipped with high output equivalent to fluorescent lights, we have achieved a reduction in power consumption from 91W to 40.5W, approximately 55% less compared to our conventional explosion-proof fluorescent fixtures. Additionally, we have reviewed the design of the LED module and housing, achieving a lightweight and compact form. With glare reduction and high color rendering (Ra83), it also contributes to improving the work environment. ★ZONE 1 (Class 1 location): Areas where explosive atmospheres may be generated during normal operation of plants, etc. ★ZONE 2 (Class 2 location): Areas where explosive atmospheres are not likely to be generated during normal operation of plants, etc., and if they do occur during abnormal conditions, they exist only for a short time. 【Features】 ■ Three types to choose from (equivalent to 1-lamp and 2-lamp FHF32W high-output type, and equivalent to FHF16W high-output type) ■ Achieved approximately 27% weight reduction for 2-lamp and about 21% for 1-lamp compared to our conventional explosion-proof fluorescent fixtures ■ Size reduction of about 33% for the 1-lamp type *For more details, please refer to the materials. Feel free to contact us with any inquiries.

The first in the domestic industry: Emergency LED lighting equipment that can be used in explosion-proof areas. Certified by the Industrial Safety and Technology Association, approved by the Minister of Land, Infrastructure, Transport and Tourism, displaying the JIL mark.

The first in the domestic industry: Emergency LED lighting fixtures that can be used in explosion-proof areas Launch of explosion-proof emergency LED lighting fixtures (VZAA series) We have launched the first explosion-proof emergency LED lighting fixtures in the domestic industry that can be installed in explosion-proof areas where there is a risk of explosion or fire due to flammable gases or combustible liquids. Currently, emergency lighting fixtures specified by the Building Standards Act are limited to "incandescent lamps" and "fluorescent lamps," and the use of LEDs as emergency light sources has not been permitted. Therefore, while there have been LED emergency lighting fixtures that received certification based on the Minister of Land, Infrastructure, Transport and Tourism's certification system and passed the self-assessment of emergency lighting fixtures by the Japan Lighting Manufacturers Association, they could not be used in explosion-proof areas where there is a risk of explosion or fire. In response to the many voices wishing for the use of LED as an emergency light source even in explosion-proof areas, we have developed explosion-proof emergency LED lighting fixtures that have passed type testing from the Japan Industrial Safety and Health Association, received certification from the Minister of Land, Infrastructure, Transport and Tourism, and display the JIL mark from the Japan Lighting Manufacturers Association, making us the first in the domestic industry to do so. Orders will begin on September 15, 2016. Since the JIL mark is affixed to the product, the building confirmation process can continue smoothly as before.

Explosion-proof LED lighting fixtures LZLA series, ideal for replacing incandescent and circular fluorescent lamps in explosion-proof areas.

New Release of Explosion-Proof LED Lighting Fixtures (LZLA Series) Seiwa Electric Co., Ltd. has enhanced its lineup of LED lighting fixtures under the <Star Reds> series to meet diverse needs in the introduction of energy-saving equipment in factories and initiatives for the environment (Minamata Convention). We are pleased to announce the addition of the explosion-proof LED lighting fixtures "LZLA Series," which can be used in explosive hazardous areas Zone 1 and Zone 2, equivalent to incandescent lamps (100W, 200W) and high-output FHF32W (circular and compact fluorescent lamps). Orders will begin on May 15. The main body of the fixture utilizes aluminum die-casting, which excels in heat dissipation and lightweight design. By implementing effective heat dissipation measures, the operating temperature range has been increased to -20°C to +50°C (compared to our conventional LED products which are -20°C to +40°C), enhancing resistance to high-temperature environments. Additionally, it achieves a maintenance-free LED module lifespan of 60,000 hours while also possessing high durability and weather resistance.

In the fields of precision machinery and medical devices, precision management at the micron and nano level is essential. A key component in this is the ultra-small diameter pin gauge. In particular, pin gauges made of carbide are excellent in wear resistance and strength, achieving stable measurements. This page explains the applications and benefits of introducing ultra-small diameter pin gauges, so please take a look.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.

Combining LIXIL's aluminum profiles manufactured in Japan with precise parts delivered from the German company Schüco, perfectly matching the color and texture of both—this is a rare craftsmanship where Japan's delicacy resonates with Germany's rationality.

Stamp duty, which can be a significant cost in contract business... By switching to electronic contracts, you can reduce this cost. The PDF files of contracts used in electronic contracts do not fall under taxable documents according to the Stamp Duty Act. Therefore, by switching to electronic contracts, you eliminate the need for physical stamps. ◆ "Electronic Contracts" without worrying about stamp duty When you use electronic contracts, there is no stamp duty. Electronic contracts can prove "authenticity" and "non-repudiation" through electronic signatures with electronic certificates and timestamps from certified service providers. * Electronic signature: Ensures authenticity through email addresses, identification, and certificates of registered matters. * Certified service provider timestamp: Proves that the document "existed" at that time and in that state, indicating that it has "not been altered." ◆ For inquiries about electronic contract services, contact paperlogic! "paperlogic Electronic Contract" is a cloud service specialized in electronic contracts and document management. It can be used not only for managing estimates and invoices but also for electronic contracts using witness-type (equivalent to a seal) and party-type (equivalent to a registered seal).
