“Light Tune”, inspired by the wave shape in sound, provides an emotional fresh up through light and sound in private spaces like a bathroom. The soft and light image is expressed by the repetitive ring shape. You can enjoy your favorite music with an MP3 player connected to a bathroom emergency phone. Also, the use of LED as a light source removes inconvenience in maintenance and has an energy-saving effect. Speakers are waterproof, so it can be used in places with lots of humidity like bathrooms. The heat, which is naturally generated inside LED, decreases humidity inside the fixture.
