In the top view, irradiation areas of the respective light-emitting parts are at least partially separated from each other.

A light source device includes: a light-shielding member defining an opening; a light-guide member located in the opening in a top view and including two or more divided lens portions; and a plurality of light-emitting parts disposed such that each of the plurality of light-emitting parts corresponds to a respective one of the lens portions, each of the plurality of light-emitting parts being configured to be individually turned on. Each of the light-emitting parts has an upper surface serving as a light-emitting surface. The two or more lens portions are Fresnel lenses. Irradiation areas corresponding to the light-emitting parts are at least partially different from each other.

A photography lighting device that provides a lighting source to a mobile electronic device. The mobile electronic device includes a front facing camera and a rearward facing camera. The lighting device includes a first light source movable from a first position to a second position. The first light source is rearward facing in the first position to provide illumination for the rearward facing camera. The first light source is forward facing in the second position to provide illumination for the forward facing camera. The lighting device further includes a second light source movable from a first position to a second position. The second light source is rearward facing in the first position to provide illumination for the rearward facing camera. The second light source is forward facing in the second position to provide illumination for the forward facing camera.

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.

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.

A light source device includes: a light-shielding member defining an opening; a light-guide member located in the opening in a top view and including two or more divided lens portions; and a plurality of light-emitting parts disposed such that each of the plurality of light-emitting parts corresponds to a respective one of the lens portions, each of the plurality of light-emitting parts being configured to be individually turned on. Each of the light-emitting parts has an upper surface serving as a light-emitting surface. The two or more lens portions are Fresnel lenses. Irradiation areas corresponding to the light-emitting parts are at least partially different from each other.

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.

A light source device includes: a light-shielding member defining an opening; a light-guide member located in the opening in a top view and including two or more divided lens portions; and a plurality of light-emitting parts disposed such that each of the plurality of light-emitting parts corresponds to a respective one of the lens portions, each of the plurality of light-emitting parts being configured to be individually turned on. Each of the light-emitting parts has an upper surface serving as a light-emitting surface. The light-shielding member covers a portion of the light-emitting surface of at least one of the plurality of light-emitting parts in the top view. Irradiation areas corresponding to the light-emitting parts are at least partially different from each other.
