This disclosure discloses a light-emitting device. The light-emitting device is capable of receiving a periodic voltage signal comprising a first voltage signal and a second voltage signal. The light-emitting device comprises: a first light-emitting unit; a second light-emitting unit; and a first switching unit comprising at least three switches for receiving the periodic voltage signal. The at least three switches are electrically connected with the first and second light-emitting units such that the first and second light-emitting units are connected in parallel with each other in the first voltage signal, and are connected in series with each other in the second voltage signal. |
