An optical lighting accessory is described for use with a handheld mobile device in photography or videography applications. The handheld mobile device includes at least a front-facing camera and light source. The optical lighting accessory includes 1) an optical element, the optical element configured to receive and capture a plurality of light rays from the light source of the handheld mobile device, 2) a light receiver panel for transforming the light source into a diffused lighting, and 3) a pair of attachment members or accessory case coupled to the light receiver panel, the pair attachment members or accessory case are configured to receive and fasten to the handheld mobile device, and a diffuser layer of the light receiver panel is configured to provide the diffused light to the front-facing camera.

A lighting module which provides adjustably controllable illumination of a camera field of view of a camera module includes an adjustable collimator which can be adjustably positioned such that the emitted light beam is adjustably directed to illuminate various regions of various camera fields of view. The collimator can be adjusted via an actuator which adjustably positions the collimator relative to static components of the lighting module, including the light emitter. The light beam can be directed to illuminate a selected limited region of a camera field of view, based on identification of a subject within the limited region. The light beam can be adjustably directed based on user interactions with a user interface, including adjusting the light beam according to user-commanded beam angle, intensity, and direction. The light beam can be adjustably directed to illuminate a region according to different fields of view of different camera modules.

Disclosed is a lighting box for taking an exposure of an object, having a casing defining a closed housing for an object to be examined and including a bottom and a cover, a lighting system including a plurality of light sources disposed around the casing, the casing acting as a light guide over its entire extent in order to ensure substantially uniform lighting of the housing.

An infrared projector and an infrared observation system by which unevenness of wavelengths in a projection pattern is reduced are provided. An infrared projector (100) is provided with infrared semiconductor laser elements (11a to 11d) that emit near-infrared laser light beams (L1a, L1b, L1c, and L1d), a scattering member (51) that receives and scatters the near-infrared laser light beams, and a projecting member (61) that projects the near-infrared laser light beams scattered by the scattering member.

An illumination apparatus includes a light source, a light-receiving unit, and a light guide unit formed in an arc shape. The light guide unit includes a light incidence section on which light from the light source is incident. The light incidence section is disposed on an outer circumferential side of the light guide unit, and faces the light source. The light guide unit further includes a first reflecting section having a first and a second region, and a second reflecting section having first and second surfaces. The first surface reflects the light incident from the light incidence section toward the first region, and the second surface reflects the light incident from the light incidence section toward the second region. The light-receiving unit is disposed at a position between the first and the second surfaces.
