We would like to introduce a case study of our project converting mercury lamps to LED. We conducted local illuminance measurements to understand the situation on-site. The existing mercury lamp was an MF700, but upon calculating the illuminance, we found that it was possible to achieve the required brightness without needing to use an MF700 class. In other words, "This is what we have now, so we need this" leads to over-specification. To achieve the necessary brightness, it is essential to confirm through illuminance design. 【Case Summary】 ■ Company: Chugoku Electric Power Company ■ Project Details: LED conversion design for the power generation room *For more details, please refer to the PDF document or feel free to contact us.

Ultraviolet sterilization is determined not only by the wavelength but also by the "ultraviolet intensity," "distance," and "time" in which the target bacteria can be inactivated. In other words, the size of the area or room being targeted is significantly involved. Our company investigates how much ultraviolet intensity reaches the room or object, and then examines the cumulative sterilization amount for the target bacteria to ultimately derive the irradiation time. This simulation allows us to visualize areas that are not exposed to ultraviolet light, which can also lead to a reduction in subsequent work.
