A light output estimation method for light-emitting device is a method for estimating light output of a light-emitting device that has a nitride semiconductor light-emitting element. The light output estimation method for light-emitting device includes a first estimation criterion to estimate light output of the light-emitting device in a period before a predetermined accumulated light emission time TX, and a second estimation criterion to estimate light output of the light-emitting device in a period after the predetermined accumulated light emission time TX. The first estimation criterion and the second estimation criterion are different criteria.
A light output estimation method for light-emitting device to estimate light output of a light-emitting device comprising a nitride semiconductor light-emitting element, the method comprising:
