Title:
LASER ILLUMINATING LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2021/027212
Kind Code:
A1
Abstract:
The present invention relates to the technical field of illuminating light sources, and specifically sets forth a laser illuminating light source, comprising a laser array, an excited module and a focusing lens. The laser array comprises a plurality of lasers that are arranged in an array and used for emitting multi-beam excitation light. The excited module comprises a wavelength conversion device used for forming a plurality of excited spots and performing multi-spot conversion on the multi-beam excitation light emitted by the laser array to convert same into excited laser light; and an optical path adjusting device used for guiding the multi-beam excitation light and the excited laser light into the focusing lens. The focusing lens is used for focusing received multi-beam laser light onto a light source focusing surface. The present invention sets forth a laser illuminating light source. Multi-beam excitation light emitted by the laser array is not converged to one spot for excitation and conversion, but is transmitted to a wavelength conversion device that forms a plurality of excited spots for multi-spot conversion. By means of diffusing heat sources, the problem in which heat from light concentration being concentrated burns the wavelength conversion device is solved, and the service life of the light source is increased.
