Sewa Electric's lighting will assist everyone supporting the sewer site.
Thank you for your continued support of Hoshikawa's industrial lighting fixtures and control equipment. We are committed to contributing to the creation of a prosperous society through the development of new products, with the theme of "delivering safety." At Hoshikawa Electric, we provide products tailored to the environment of wastewater treatment facilities to ensure a safe and appropriate working environment. Are you troubled by hydrogen sulfide in your wastewater and sewage treatment facilities? In factories and wastewater treatment facilities, hydrogen sulfide is generated when wastewater and sludge decompose. Hydrogen sulfide not only causes unpleasant odors but also leads to many problems. 1. Odor: Hydrogen sulfide has a foul smell similar to rotten eggs, even at low concentrations. 2. Corrosion: Hydrogen sulfide can cause corrosion of electronic devices and concrete. At Hoshikawa Electric, we conduct tests on LED lighting fixtures for hydrogen sulfide, taking into account the facilities and their installation environments, to confirm their performance.

Company information
Hoshia Electric has established itself as a top manufacturer in various fields, including information display systems such as road information boards, industrial lighting known for its waterproof and explosion-proof features under the name "Water Pearl," tunnel lighting that began with the full-scale installation in the Kanmon Tunnel, and resin products represented by "Cutting Duct." As a new business, we started an electromagnetic noise countermeasure (EMC) product business in 1997 to address electromagnetic noise issues arising from digital devices. In the LED business, we successfully developed a blue light-emitting diode in April 2002 and a white light-emitting diode in December of the same year. Based on these technologies, we are actively expanding our business in the field of LED lighting fixtures, ranging from roads and tunnels to industrial lighting. On March 9, 2018, Hoshia Electric Co., Ltd. was listed on the Tokyo Stock Exchange First Section. In April 2022, we transitioned to the Tokyo Stock Exchange Standard Market. Moving forward, we will continue to leverage our creative thinking and technological capabilities cultivated thus far to develop even more innovative products and strive for business expansion.
