Abstract

An LED light source performance compensation apparatus and a white-light LED light-emitting device. The LED light source performance compensation apparatus comprises: a light transmissive supporting member (), wherein the light transmissive supporting member () is provided with a light performance parameter regulation member (); and after secondary light of which the wavelength is 380 nm-780 nm and which is emitted by an LED light source () passes through the performance compensation apparatus, light performance parameters are adjusted. The LED light source performance compensation apparatus can effectively regulate the light performance parameters of the LED light source, thereby remedying the defects of the secondary light emitted by an existing finished LED light source in terms of light performance parameters.
