Title:
COMPOUND EYE MODULE, LIGHT SOURCE APPARATUS, AND PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/017263
Kind Code:
A1
Abstract:
A compound eye module (3), comprising a plurality of compound eyes (31). The plurality of compound eyes (31) can be assembled and fitted according to predetermined requirements to form the compound eye module (3) having a specific optical function. Also provided is a light source apparatus (100), comprising a light-emitting device group (1), a light-combining module (2), and the compound eye module (3). The light-emitting device group (1) is used for emitting a plurality of light beams; the light-emitting device group (1) comprises a plurality of light-emitting devices (11); each light-emitting device (11) emits a light beam; the light-combining module (2) is used for guiding the plurality of light beams emitted by the light-emitting device group (1) to form a plurality of light spots; the compound eye module (3) performs dodging processing on the plurality of light spots guided by the light-combining module (2); and the compound eyes (31) have one-to-one correspondence to the light spots. Also provided is a projection device using the light source apparatus (100). The compound eye module (3), the light source apparatus (100), and the projection device have good dodging effect, high process feasibility, and small light source size.
