The invention provides a light-emitting device which comprises a plurality of light-emitting units and a first dimming structure, and the first dimming structure is arranged on the light-emitting units. When a first number of the light emitting units is turned on, the light emitting device provides a first viewing angle related to the first number of the light emitting units, and when a second number of the light emitting units is turned on, the light emitting device provides a second viewing angle related to a second number of the light emitting units. The first visual angle is smaller than the second visual angle. 本发明提供一种发光设备，其包括多个发光单元与第一调光结构，其中第一调光结构设置在发光单元上。当发光单元中的第一数量被开启时，发光设备提供相关于发光单元的第一数量的第一视角，当发光单元中的第二数量被开启时，发光设备提供相关于发光单元的第二数量的第二视角。第一数量小于第二数量，第一视角小于第二视角。
