New Release of Explosion-Proof LED Lighting (LZWA Series) Seiwa Electric Co., Ltd. is launching the explosion-proof LED lighting fixtures (LZWA series) as a new lineup in the <STARLED★S> series, which will be the first internationally certified explosion-proof product in the domestic industry for base lighting fixtures. The explosion-proof LED lighting fixtures (LZWA series) aim for a compact and lightweight design while ensuring illumination and light distribution equivalent to traditional fluorescent fixtures (HF fluorescent 45W x 2 lamps). The dimensions are within 30 cm in both width and height, and the weight is only 5 kg. This reduces the burden of installation work and improves safety due to the smaller pressure-bearing area. As for explosion-proof standards, it has obtained international explosion-proof certification IECEx (IEC60079-0, -1), as well as European explosion-proof certification ATEX (LZWA12041). Models with Chinese explosion-proof certification NEPSI (LZWA14041-CA) are also included in the lineup, achieving many international standards (*). * This product is sold only for overseas markets. Domestic explosion-proof certification has not been obtained. * The Taiwanese distributor is listed on the following website.

Recently, Japan has been struck by significant natural disasters (such as typhoons, heavy rains, and earthquakes). The large earthquake with a seismic intensity of 7 that hit Hokkaido in September 2018 (the Hokkaido Eastern Iburi Earthquake) resulted in a widespread blackout across the entire region due to a loss of power supply, which is still fresh in our memories. Additionally, the anticipated occurrence of the Nankai Trough earthquake, a capital region earthquake, and abnormal weather due to global warming cast a shadow of anxiety over our lives. In such times, the portable uninterruptible power supply LioUPS3, which can be set up and operated in outdoor environments, plays a vital role. Normally, it can be installed as a backup power source for other devices, and in the event of a power outage caused by natural disasters such as earthquakes, typhoons, heavy rains, or electrical equipment troubles, it can be transported by car to the desired location to restore power and be temporarily operated. Seiwa Electric aims to contribute to society with the goal of "disaster reduction" based on two categories: Category 1: Providing rapid and accurate evacuation guidance during disasters. Category 2: Providing backup power sources during disasters.

In urban areas such as large cities, power outages can occur due to various troubles that cause a sudden drop in voltage. When a power outage happens, traffic lights for vehicles and pedestrians installed on the roads go out, paralyzing the traffic network. Although police officers will manage traffic, the time until restoration is unpredictable. In such situations, the portable uninterruptible power supply LioUPS3, which can be set up and operated in outdoor environments, plays a vital role. Typically, it is kept as a backup power source for other devices, and in the event of a power outage caused by natural disasters such as earthquakes, typhoons, heavy rain, or electrical equipment troubles, the uninterruptible power supply can be transported by car to the traffic lights that need to be restored, allowing them to be powered back on and temporarily operated as traffic signals.
