Lighting fixtures consist of a light source (LED, fluorescent lamp, HID, etc.) and a fixture body that holds and controls it (housing, optical system, power circuit, control circuit). In the manufacturing industry, they are used in a wide range of environments such as factories, warehouses, offices, cleanrooms, and outdoor facilities, and are characterized by the demand for high efficiency, long life, environmental resistance (dustproof, waterproof, explosion-proof), and smartification (IoT integration, dimming/color tuning, network control). Their applications contribute to ensuring visibility in work spaces, improving safety, and enhancing productivity, with special uses such as inspection lighting and plant factories also existing. Representative services include optimal lighting design consulting, manufacturing and sales of fixtures, installation work, maintenance, proposals for energy-saving replacements, and support for smart lighting system construction and operation. This is an indispensable category for reducing environmental impact and improving work environments.
