Abstract

Alight emitting device, comprising a light-transmitting carrier and a light emitting body. The light-transmitting carrier is formed with a holding cavity, a plurality of connecting points are disposed on an inner wall of the holding cavity, and the light emitting body are disposed within the holding cavity by connecting with connecting points. The light emitting device cleverly utilizes the connecting points to restrain the light emitting body in the holding cavity, causing that the light emitting body is freely shaped and accurately positioned in three-dimensional space, so as to form a planar light source or a three-dimensional light source that are restrained within the holding cavity through the connecting points, thereby enhancing the visual effect of the lamps and lanterns, making the lamps and lanterns better adapt to the lighting needs of different scenes and atmospheres, and more finely controlling distribution and change of light, and creating a more comfortable and hierarchical three-dimensional lighting effect.
