Title:
LIGHT-EMITTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/062542
Kind Code:
A1
Abstract:
The present invention relates to the technical field of stage lights and provides a light-emitting apparatus, comprising an LED array comprising a plurality of LED unit modules, each LED unit module comprising at least one LED chip, and the light-emitting area of the LED unit module being substantially circular; a collimation lens array, used for performing collimation on the light rays emitted by the LED unit modules; and a condenser lens, used for focusing the light rays collimated by the collimation lens array onto a preset focal plane to form a substantially circular light spot. The present invention sets the light-emitting area of the LED unit modules to be substantially circular and forms a substantially circular and uniform light spot on the focal plane without homogenisation by opposite fly-eye lenses, greatly reducing costs and obtaining light spots with a better light emission effect; the present invention also increases the photoelectric efficiency, light emission efficiency, service life, and stability of the LED chips and the wafer utilisation rate of the LED chip manufacturing, and reduces the junction temperature and production costs of the LED chips.
