PROBLEM TO BE SOLVED: To provide a light-emitting device capable of reducing a feeling of wrongness given to a user.SOLUTION: As an example of a light-emitting device a light therapeutic device 10 comprises: a white light source 11w； a blue light source 11b； and a control part 12. The control part 12 performs a stationary light-emitting control which makes the white light source 11w and the blue light source 11b severally emit in specific brightness, and performs a dimming control which is performed after the stationary light-emitting control and dims the white light source 11w and the blue light source 11b severally. The control part 12 at the dimming control starts dimming the blue light source 11b before the white light source 11w, and puts out the blue light source 11b simultaneously with the white light source 11w or before the white light source 11w.SELECTED DRAWING: Figure 2【課題】ユーザに与える違和感を低減することができる発光装置を提供する。【解決手段】光施療装置１０は、発光装置の一例であって、白色光源１１ｗと、青色光源１１ｂと、制御部１２とを備える。制御部１２は、白色光源１１ｗ及び青色光源１１ｂのそれぞれを一定の明るさで発光させる定常発光制御、並びに、定常発光制御の後に行われる減光制御であって、白色光源１１ｗ及び青色光源１１ｂのそれぞれを減光する減光制御を行う。制御部１２は、減光制御において、青色光源１１ｂを白色光源１１ｗよりも先に減光開始させ、かつ、青色光源１１ｂを、白色光源１１ｗと同時または白色光源１１ｗよりも先に消灯させる。【選択図】図２
