Title:
LIGHT SOURCE ADJUSTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/010782
Kind Code:
A1
Abstract:
A light source adjusting apparatus (100), comprising: a light source mechanism (10) provided with at least one group of light-emitting bodies (11), the at least one group of light-emitting bodies (11) comprising at least two different types of light-emitting body; a gathering lens mechanism (60) and/or a collimating lens mechanism (20), used to gather and/or collimate the light beam emitted by the light source mechanism (10); and a position adjusting mechanism (30), comprising a connection assembly connected to the light source mechanism (10), the collimating lens mechanism (20) or the gathering lens mechanism (60), a guide structure for directional motion of the connection assembly, and a driving member (33) for driving the connection assembly to move along the guide structure. By means of providing at least two different types light emitter on the light source mechanism (10), and by means of providing a position adjusting mechanism (30) connected to the light source mechanism (10), the collimating lens mechanism (20) or the gathering lens mechanism (60), and thereby controlling the collimating lens mechanism (20) or the gathering lens mechanism (60) to move relative to the light source mechanism (10), a lens unit on the collimating lens mechanism (20) or the gathering lens mechanism (60) can be aligned with different light-emitting bodies to be collimated or gathered, thereby achieving different light spot effects.
