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 oral photography system and method can include: a chassis, the chassis including a chassis base and a vertical chassis extension, the vertical chassis extension extending upward from the chassis base, and the vertical chassis extension including: a magnetic clamp having a first clamping element for securing an imaging device to the vertical chassis extension, the imaging device including a second clamping element, a diffusion panel attachment coupled to the vertical chassis extension, and a light panel attachment coupled to the vertical chassis extension; a diffusion panel releasably affixed to the diffusion panel attachment; and a light panel releasably affixed to the light panel attachment.

Photographic lighting devices, systems, and methods having a plurality of electrical energy storage/discharge (EESD) elements and/or one or more light sources in a single photographic lighting device to perform one or more photographic lighting effects. EESD elements and one or more light sources can be configured to have multiple separate light emissions occur in a single image acquisition window. The multiple light emissions are separated in an image acquisition window by a time period that is about shutter speed exposure time/(N1), where N is the number of light emissions. In one such example, two light emissions are separated by a time period that is about shutter speed exposure time/(N1).

A flash housing for photographic purposes is disclosed. The flash housing comprises a flash forming element arranged to generate a flash light and a lens element arranged to let at least part of the generated flash light out of the flash housing so as to obtain the flash. The obtainable flash light has a beam lobe with a controllable beam angle. A simulation light generator element is arranged for simulation of the obtainable flash light beam lobe having the controllable beam angle.

The disclosed technology relates to a hard and soft light module having a housing with a first surface that accommodates a lens. A first plurality of LEDs are disposed along a periphery of the first surface, the first plurality of LEDs are configured to generate light in a first direction toward an edge of the lens. A second plurality of LEDs are disposed proximate to the first surface, the second plurality of LEDs are configured to generate light in a second direction through the lens. The first plurality of LEDs are configured to generate a soft light and the second plurality of LEDs are configured to generate a hard light.

A light source module includes an array of illumination elements and a light diffusing material. The light source module is configured to receive a control signal for adjusting diffusion of light emitted from the light source module and in response adjust the amount of diffusion of light emitted from the light source module. A light source module may include a segmented light diffusing material where each segment is associated with an illumination element. And individual segments may have light diffusing properties that are different than other segments of the light diffusing material. Some illumination elements may emit light of a different color spectrum than other illumination elements, and a light diffusing material may scatter the different colored light to illuminate a scene with combinations of light of different colors. A light source module may be embedded in a mobile computing device.

A flash system for an electronic device includes a ring-shaped light guide having a central opening. A camera lens is positioned in or behind the opening. A first light emitting diode (LED) is mounted on a printed circuit board (PCB), and the LED and PCB are encapsulated by a molded light guide of the flash system. An identical LED and PCB are encapsulated at an opposite end of the molded light guide (i.e., 180 degrees away). The back surfaces of each PCB diffusively reflects light from the LED on the other PCB. Light extraction features on the light guide surface uniformly leak out light from the LEDs. The light emission profile of the light guide has a peak axially aligned with the central opening of the light guide and rolls off to the edge of the camera's field of view.

An oral photography system and method can include: a chassis, the chassis including a chassis base and a vertical chassis extension, the vertical chassis extension extending upward from the chassis base, and the vertical chassis extension including: a magnetic clamp having a first clamping element for securing an imaging device to the vertical chassis extension, the imaging device including a second clamping element, a diffusion panel attachment coupled to the vertical chassis extension, and a light panel attachment coupled to the vertical chassis extension; a diffusion panel releasably affixed to the diffusion panel attachment; and a light panel releasably affixed to the light panel attachment.

The present invention is an on-camera flashlight, comprising a lower light holder and a top light holder freely rotatably connected to the lower light holder. A flashlight light source is mounted on the top of the top light holder. The light emitting diode and the flashlight light source are mounted on the on-camera flashlight, combined for ease of use. Two functions-in-one lighting device saves space, avoids overloading the camera, and makes it portable. Because the two light sources are set in combination, the cooperation and sequence of the two light sources are easier to control. As the light emitting diode is mounted on the top light holder which may freely rotate with respect to the lower light holder, the light emitting diode may also freely rotate. It is also convenient to adjust the light direction. Above features all remarkably facilitate operation and versatility of the on-camera flashlight.
