ILLUMINATING DEVICE AND MANUFACTURING METHOD THEREOF

摘要

An illuminating device is provided, which includes: a substrate (110, 210), and a light source (120, 220) and a light-emitting layer (131, 132, 133, 231, 232, 233) which are disposed on the substrate (110, 210). A wavelength of light emitted by the light source (120, 220) is smaller than a wavelength of light emitted after the light-emitting layer (131, 132, 133, 231, 232, 233) is excited, the light emitted by the light source (120, 220) is adapted for exciting the light-emitting layer (131, 132, 133, 231, 232, 233) to emit light, and the light-emitting layer (131, 132, 133, 231, 232, 233) is made from a long-persistence material. The illuminating device achieves emergency lighting in the case of no power supply.
