An apparatus for a digital imaging device includes a housing, a controller within the housing, and at least one illumination element in communication with the controller. The controller is configured to control at least one of an intensity and/or volume of light emitted by the at least one illumination element in dependence upon a distance of the apparatus from a target surface.

An illumination system is provided for an optical system that includes an imaging device for acquiring an image of a target, for decoding of a symbol or other analysis. The illumination system can include a first light source configured to provide illumination of a first wavelength, a second light source configured to provide illumination of a second wavelength that is different from the first wavelength. The light sources can be controlled for operations that include: illuminating the target with the first and second light sources simultaneously for acquisition of the image of the target; and altering an illumination output of at least one of the first light source or the second light source, while maintaining non-zero illumination output for at least one of the first light source or the second light source, to indicate a status of the optical system.

An imaging apparatus includes an imaging element, a lens unit that focuses light on the imaging element, and a light source disposed around the lens unit. The lens unit includes a blocking part that projects over a region located around the lens unit and facing the light source so as to block stray light from the light source.

A strobe module can include a Fresnel lens that defines an external surface of the strobe module and a sidewall at least partially defining an internal volume and defining an external channel. A gasket can be disposed in the external channel. A substrate can be coupled to the sidewall to further define the internal volume and a light source can be disposed on the substrate in the internal volume.

Methods, systems, and apparatus are provided for manufacturing a flash module. In some implementations, the method includes mounting at least one LED module on a top portion of a first substrate for providing light. A lens portion is mounted on a second substrate in a first region of the second substrate. The lens portion illuminates the light from the at least one LED module and the second substrate comprises the first region having a first diameter and a second region for providing a path for the illuminating light having a second diameter. The first diameter is greater than the second diameter. The second substrate is mounted on the first substrate. A substance is applied to a top portion of the second substrate from an end of the first diameter to the end of the second diameter and to a side portion of the second substrate in the second region.

A case for portable electronic devices such as smartphones includes a feature to prevent glare from a flash from affecting images and video captured by a camera lens and also may include a battery to extend battery life of the electronic device. Smartphones have telephony, Internet connectivity, and camera and video features. Photos and video may be uploaded through the Internet or sent to other phones. The case has a hole for a camera flash of the smartphone. The edging of the hole is colored black or another dark color to prevent glare from appearing in the photos or video taken by the smartphone when using the camera flash.

The present disclosure relates to optical systems, vehicles, and methods that are configured to illuminate and image a wide field of view of an environment. An example optical system includes a camera having an optical axis and an outer lens element disposed along the optical axis. The optical system also includes a plurality of illumination modules, each of which includes at least one light-emitter device configured to emit light along a respective emission axis and a secondary optical element optically coupled to the at least one light-emitter device. The secondary optical element is configured to provide a light emission pattern having an azimuthal angle extent of at least 170 degrees so as to illuminate a portion of an environment of the optical system.

A decorative film includes a film body and a decorative layer. The film body is made of a transparent or semi-transparent material. The decorative layer is disposed at the film body and includes a texture layer and/or a semi-transparent colored ink layer, where the texture layer is transparent or semi-transparent. When the light-emitting element emits no light, the texture layer enables the decorative film to present at least one of a pattern effect, a dazzle effect, a matt effect, or a color-change effect, and the semi-transparent colored ink layer enables the decorative film to present the same color as the semi-transparent colored ink layer. When the decorative film is applicable to the light-emitting module, the decorative film covers the light-emitting surface of the light-emitting element, which can not only protect the light-emitting element, but also decorate the light-emitting module in a non-light-emitting state.

The present disclosure relates to cantilevered and divergent view wearable optical systems that redirect an optical path, and provide for optimal ergonomics coupled with vision enhancement and vision magnification. Methods of use, devices, and kits are also contemplated.
