Abstract

A combined optical lens module and an optical imaging device with the combined optical lens module are provided. The optical imaging device includes a visible light-emitting unit, an invisible light-emitting unit, at least one visible light lens group and at least one invisible light lens group. After a visible light beam is transmitted through the at least one visible light lens group, a propagating direction of the visible light beam is changed. After an invisible light beam is transmitted through the at least one invisible light lens group, a propagating direction of the invisible light beam is changed.

First claim

What is claimed is:

1. A combined optical lens module, comprising:
plural optical lens groups comprising at least one visible light lens group and at least one invisible light lens group, wherein after at least one visible light beam is transmitted through the at least one visible light lens group, a propagating direction of the at least one visible light beam is changed, wherein after at least one invisible light beam is transmitted through the at least one invisible light lens group, a propagating direction of the at least one invisible light beam is changed; and
a housing accommodating the plural optical lens groups,
wherein one of the plural optical lens groups is a center optical lens group, and the other optical lens groups of the plural optical lens groups are peripheral optical lens groups around the center optical lens group, and an included angle is formed between a center optical axis of the center optical lens group and a peripheral optical axis of each of the plural peripheral optical lens groups.

2. The combined optical lens module according to claim 1 , wherein the center optical lens group is one of the at least one visible light lens group or one of the at least one invisible light lens group.

3. The combined optical lens module according to claim 1 , wherein the included angle is determined according to a position of a viewer or the included angle is smaller than 20 degrees.

4. The combined optical lens module according to claim 1 , wherein the plural optical lens groups comprise at least two integrally formed and interconnected lenses.

5. The combined optical lens module according to claim 1 , wherein an image shown on a display element is illuminated by the at least one visible light beam, and the image is projected out after the at least one visible light beam is transmitted through the at least one visible light lens group; each of the at least one invisible light lens group comprises a lens, and the at least one invisible light beam is introduced into the lens through a first surface of the lens and outputted from a second surface of the lens; the at least one invisible light beam comprises at least one of an ultraviolet light beam, an infrared light beam, a near infrared light beam and a far infrared light beam; or the combined optical lens module is included in a wearable mobile device or a wearable device.

6. An optical imaging device with a combined optical lens module, the optical imaging device comprising:
at least one visible light-emitting unit providing plural visible light beams;
at least one invisible light-emitting unit providing plural invisible light beams; and
plural optical lens groups comprising at least one visible light lens group and at least one invisible light lens group, wherein after at least one portion of the plural visible light beams is transmitted through the at least one visible light lens group, a propagating direction of the at least one portion of the plural visible light beams is changed, wherein after at least one portion of the plural invisible light beams is transmitted through the at least one invisible light lens group, a propagating direction of the at least one portion of the plural invisible light beams is changed,
wherein the at least one visible light lens group at least comprises a first visible light lens group corresponding to a first image and a second visible light lens group corresponding to a second image, wherein the first image is transmitted through the first visible light lens group and projected on a first projection block, and the second image is transmitted through the second visible light lens group and projected on a second projection block.

7. The optical imaging device according to claim 6 , wherein the optical imaging device is an optical projection apparatus, and the optical projection apparatus comprises at least one display element, wherein the first image and the second image are shown on the at least one display element and illuminated by the at least one portion of the plural visible light beams, and the first image and the second image are projected out after the at least one portion of the plural visible light beams is transmitted through the corresponding visible light lens group.

8. The optical imaging device according to claim 7 , wherein the at least one display element is a single display element showing the first image and the second image, or the at least one display element comprises a first display element showing the first image and a second display element showing the second image.

9. The optical imaging device according to claim 8 , wherein the first projection block and the second projection block are coplanar or non-coplanar; the first projection block and the second projection block are at least partially overlapped or not overlapped; or the first image and the second image are simultaneously projected out or successively projected out.

10. The optical imaging device according to claim 6 , wherein one of the plural optical lens groups is a center optical lens group, and the other optical lens groups of the plural optical lens groups are peripheral optical lens groups around the center optical lens group.

11. The optical imaging device according to claim 10 , wherein the center optical lens group is one of the at least one visible light lens group or one of the at least one invisible light lens group; or an included angle is formed between a center optical axis of the center optical lens group and a peripheral optical axis of each of the plural peripheral optical lens groups.

12. The optical imaging device according to claim 6 , wherein the optical imaging device further comprises a housing accommodating the plural optical lens groups; the at least one invisible light beam comprises at least one of an ultraviolet light beam, an infrared light beam, a near infrared light beam and a far infrared light beam; or the plural optical lens groups comprise at least two integrally formed and interconnected lenses.
