摘要：

A light-emitting apparatus includes a solid-state light source and a wavelength conversion device. The solid-state light source emits first light of 480 to 550 nm or 430 to 470 nm. The wavelength conversion device contains a red phosphor with a Ce luminescent center. The red phosphor is excited by at least part of the green light to emit second light. The second light has a spectrum with a peak wavelength in the range of 600 to 700 nm.
