Abstract
The inventive light-emitting device for emitting starry light comprises at least one optical fiber, each having a core, a cladding around the core and opaque cover layer around the cladding, wherein a plurality of micro-windows are formed on each optical fiber such that part of the light propagating along the core emits through the micro-windows, and provides starry light effect to the mesh woven by the optical fiber.
