Seiko and Denki will be exhibiting at the Lighting Fair 2019.

This single unit provides reliable lighting for both normal and emergency situations! It is a waterproof emergency lighting fixture with an IP55 protection rating, suitable for outdoor use.

The moisture-proof and waterproof emergency LED lighting fixtures (VYAA and VYBA series) comply with protection rating IP55 and can be installed in indoor environments where dust is generated or in outdoor environments without a roof. The inherent energy consumption efficiency is 142 lm/W (*1), achieving one of the highest energy efficiencies in the industry for waterproof emergency LED lighting fixtures. Additionally, by offering two types of body materials—stainless steel for the LYAA series and steel plate for the LYBA series—we provide a total of 160 models with a rich variety of products, allowing you to choose the optimal model according to the installation location. Separate from the light source that operates normally, the emergency light source, which lights up during a power outage using a built-in rechargeable battery, is consolidated at the end of the fixture. When installed in the same area as the moisture-proof and waterproof LED fixtures (LYAA and LYBA series), the design can be unified. Furthermore, the installation spacing during emergency lighting can be wider than that of conventional light sources (fluorescent lamps), allowing for a reduction in the number of installations. This helps to keep initial costs down during new installations or upgrades. <Product Variations> Total of 160 models Brightness: 5 types Mounting types: 8 types Body materials: 2 types Light source color (color temperature): 2 types

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.

Contributing to the all-LED lighting in industrial areas! Launching fluorescent lamp alternatives equipped with LED emergency light units and sealed emergency LED lighting fixtures.

The sealed emergency LED lighting fixtures (VCMA series) comply with protection rating IP55 and can be installed in indoor environments where dust is generated or in outdoor environments without a roof. Utilizing our unique optical design technology, we ensure efficient brightness in both normal and emergency situations through light distribution control. Particularly during emergency lighting, the installation spacing can be wider than traditional light sources (fluorescent lamps), allowing for a reduction in the number of units installed and lowering initial costs. The straight tube LED lamp, which serves as the light source during normal operation, is housed in a highly sealed lamp protection cover, making it resistant to dirt and corrosion, and protecting the lamp from external impacts. Since a straight tube LED lamp is used, lamp replacement is possible. During a power outage, the emergency light source is consolidated at the end of the fixture and lights up using a built-in battery. When installed in the same area as the sealed LED fixtures (LCMA series), the design can be unified. Additionally, a lamp monitor (green) lights up to indicate the charging status of the emergency light at a glance. If the green lamp is lit during normal operation, it indicates normal function; if the lamp monitor is off, it is time to replace the rechargeable battery due to its lifespan. The estimated lifespan of the rechargeable battery is 4 to 6 years. Battery replacement can be easily and quickly performed while the fixture is installed.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Environmental Industry Expo 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition aims to pave the way for a sustainable future from the local community. It is a trade fair for environmental-related industries originating from the Minami-Shinshu region of Nagano Prefecture. Our company will introduce next-generation solutions for reducing environmental impact and effectively utilizing energy, including our "smokeless small incinerator" and "stove," along with product panels and case studies. No pre-registration is required, and admission is free. We sincerely look forward to your visit.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue. We sincerely look forward to your visit.
