OPTICAL DEVICE AND LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/187205
Kind Code:
A1
Abstract:
An optical device and a lighting device. An optical device (12) comprises a conductive cavity (120), a first optical module (122), a second optical module (124), and a third optical module (126). The conductive cavity (120) has a light incidence end (X1); the first optical module (122), the second optical module (124), and the third optical module (126) are fixed in the conductive cavity (120), wherein the first optical module (122) is adjacent to the light incidence end (X1) and is located between the light incidence end (X1) and the second optical module (124), and the second optical module (124) is located between the first optical module (122) and the third optical module (126); the conductive cavity (120), the first optical module (122), and the second optical module (124) together enclose a first resonance space (SP1); and the conductive cavity (120), the second optical module (124), and the third optical module (126) together enclose a second resonance space (SP2).
