Abstract:
1. A light-emitting device, comprising: a substrate; a first semiconductor light-emitting structure formed on the substrate, wherein the first semiconductor light-emitting structure comprises: a first semiconductor layer having a first conductivity type; a second semiconductor layer having a second conductivity type; and a first active layer formed between the first semiconductor layer and the second semiconductor layer, wherein the first active layer is capable of emitting a first light having a first dominant wavelength; and a first thermal-sensitive layer formed on a path of the first light, wherein the first thermal-sensitive layer comprises a material characteristic which varies within a temperature range and a first intensity difference of the first light after being transmitted through the first thermal-sensitive layer within the temperature range is smaller than a second intensity difference of the first light before being transmitted into the first thermal-sensitive layer within the temperature range.
