摘要:
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.

Photographic lighting devices and systems having multiple electrical energy storage/discharge (EESD) elements and/or multiple light sources in a single photographic lighting device to perform one or more photographic lighting effects. In one exemplary aspect, independent control of one or more light sources connected to a first EESD bank and another one or more light sources connected to a second EESD bank, such as via control circuitry, may be utilized in producing various lighting effects.

A system allowing the acquisition of biometric and biographical data of an individual includes a station into which at least one of the following elements are integrated: a sensor of biometric prints, a camera for taking a picture of said individual, a feedback screen and a gantry including lighting means adapted for ensuring lighting complying with given conditions of acquisition of the biometric data. The lighting means include a curved metallic reflector fixed to the rear and to the apex of the framework of a first upper light tube placed substantially horizontally, furnished with a protection which is lowered and oriented toward said reflector, and a second light tube disposed substantially horizontally in the lower part of the framework, where the power P2 of the second lighting tube being lower than that the power P1 of the first tube.
摘要:
Illumination devices may be provided with one or more light sources that emit light of the same, similar, and/or different optical spectra within a wavelength range, for example, from the extreme ultraviolet (UV) to the far infrared (IR). One or more of the light sources may be selectively adjusted to control the overall mix of light projected onto a scene of interest. For example, one or more light sources may be used, and sometimes in conjunction with other optical elements, to provide illumination having a particular angular intensity distribution, color temperature, and/or other desired optical properties for a scene within a field of view (FOV) of the camera of a mobile device used for videography and/or photography. One or more illumination devices may also be used as flashlights and/or as sources of electrical power for recharging mobile devices. Related methods are provided.

An illumination device contains a light-emitting semiconductor chip containing a plurality of individually drivable emission regions. The illumination device furthermore contains an optical element designed to shape light emitted by the emission regions to form a beam of rays. The illumination device is designed such that different beam profiles of the beam of rays can be set by the individually drivable emission regions.
摘要:
A camera flash comprises a light guide arranged to extract light at least through one surface; and one or more light sources arranged, in use, to emit light into the lightguide. Each light source is an LED or a laser diode. The camera flash is connectable, in use, to drive circuitry, the drive circuitry being for driving the light source(s) to emit a pulse of light. The waveguide spreads out the light from the light source(s), so that a flash of light from the camera flash does not present a safety risk, while minimizing loss of the light from the light source(s). The camera flash can thus provide a high overall optical output, spread over an extended area (as defined by the waveguide). The lightguide may for example be disposed around a camera module of a mobile telephone camera.

摘要:
A system and method for converting power control value standards during photographic wireless communication from a camera to one or more remote lighting devices. A power control value of a camera may be converted to a different standard for wireless communication and converted to another standard for delivery to a remote lighting device. Different lighting devices may utilize different standards and have conversion to those appropriate standards at the receiver side even where the lighting device standard differs from the camera standard.
