NIGHT BOOK is a book-shaped LED light. Its body does not have a lighting switch. Just place NIGHT BOOK between books and pull out from its case like a book to ignite a beautiful light and create a poetic environment. NIGHT BOOK can make new experiences arising from the new way to use and new place to install. Conventional LED light focused on practicality to illuminate objects, but NIGHT BOOK uses LED light as a means to move your mind. In the era of mass production and mass consumption, NIGHT BOOK suggests a good relationship between people and industrial products.
