  • Patent number: 10299663
    Abstract: A wide-angle illumination device includes a base, a first light guiding module and two second light guiding modules. The base includes a central region and two lateral regions, and the two lateral regions are respectively located on opposite positions of the central region. A first light emitting module is disposed on the central region, and two second light emitting modules are disposed on the two lateral regions. The first light guiding module is disposed on the central region and matched with the first light emitting module, to guide a first optical signal of the first light emitting module toward a front of the base. The two second light guiding modules are disposed on the lateral regions and matched with the second light emitting modules, to guide a second optical signal of the second light emitting module out of an end of the base.

  • Patent number: 10203094
    Abstract: A light emitting device includes a casing, a lighting module, and a lens module. The lighting module is disposed in the casing for providing light and includes first and second light sources. The lens module faces the lighting module and includes a first lens aligned with the first light source, a second lens aligned with the second light source, a sliding frame, and a driving motor. The sliding frame is fixed to the first lens and has a thread portion. The driving motor has a screw rod for engaging with the thread portion, to make the sliding frame movable along the screw rod. The driving motor rotates the screw rod to make the thread portion drive the first and second lenses close to or away from the first and second light sources. Accordingly, the present invention reduces the manufacturing cost of the light emitting device and simplifies its mechanical design.

  • Patent number: 10018328
    Abstract: A light emitting module includes a lens and first and second light sources aligning with the lens. The lens includes a first biconcave section having a first light-entrance concave surface and a first light-exit concave surface, a second biconcave section having a second light-entrance concave surface and a second light-exit concave surface, and a shared section having a light-exit shared surface. A tangent slope of the shared section where the light-exit shared surface is connected to the first light-exit concave surface is less than a tangent slope of the first biconcave section where the first light-exit concave surface is connected to the light-exit shared surface. A tangent slope of the shared section where the light-exit shared surface is connected to the second light-exit concave surface is larger than a tangent slope of the second biconcave section where the second light-exit concave surface is connected to the light-exit shared surface.

  • Patent number: 10003791
    Abstract: An illumination apparatus is applied for providing illumination to a photographic device having a photographic field-of-view. The illumination apparatus includes an illumination device and a calibration photographic device. The illumination device is pivoted to a side of the photographic device and has an illumination field-of-view. The calibration photographic device has a calibration photographic field-of-view and is connected to the illumination device to make the calibration photographic field-of-view substantially overlap with the illumination field-of-view and make the calibration photographic device move together with the illumination device. The calibration photographic field-of-view at least partially overlaps with the photographic field-of-view. Accordingly, the present invention could improve convenience of the photographic device in mounting the illumination device.

  • Patent number: 9661201
    Abstract: An image monitoring apparatus includes a casing, a camera module in the casing, and a lighting module disposed on the casing and located above or under the camera module on a plane corresponding to a vertical angle of view of the camera module. A horizontal light-emitting plane of a LED of the lighting module is perpendicular to the plane corresponding to the vertical angle of view. A lens of the lighting module covers the LED and has a convex light-exit surface, a bottom surface, and a concave light-entrance surface. A long axis of the convex light-exit surface is located at the horizontal light-emitting plane. A section thickness of the lens from the concave light-entrance surface to the convex light-exit surface along the long axis is greater than a section thickness of the lens from the concave light-entrance surface to the convex light-exit surface along a normal of the bottom surface.
