コーセイジャパン List of Products and Services

This product is an LED lighting solution that can save 70% energy, designed for large floodlights ranging from 1kw mercury lamps to 2kw metal halide lamps. The light distribution is available in narrow, medium, and wide angles according to the application. It is also available in a salt damage-resistant specification.

• Mercury lamp type

The LHL series is a high-bay light designed with a wide light distribution using the latest chips (190 to a maximum of 210 lm/W) from SSC (Seoul Semiconductor). Its color rendering index (Ra) is also high, above 80, and it has received high praise as a replacement for mercury lamps in factories and warehouses. Additionally, the glare-cut type with a milky cover for the LED light-emitting surface is very popular in gymnasiums. There is no glare at all, making it ideal for sports facilities and places where light reflection is undesirable.

This product was developed in collaboration with the Fukuoka Industrial Technology Center's Mechanical and Electronic Research Institute, utilizing the Fukuoka Prefecture Manufacturing Subsidy (Fiscal Year 2014). Through thermal fluid analysis and temperature measurement, we conducted an optimal design of a heat sink shape that has high heat dissipation performance and can be produced at a low cost. Additionally, we performed optimal shape design of a reflector to achieve the desired illuminance and light distribution characteristics through optical simulation, and verified its effectiveness through lighting characteristic measurements.
