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).

Photographic lighting devices, systems, and methods 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. Multiple EESD elements and multiple light sources can be configured to have two separate light emissions occur in a single image acquisition window. 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 camera includes an image-capturing part, a plurality of lamp cups, and a plurality of lighting parts disposed in the lamp cups correspondingly. The lamp cup includes two reflection members oppositely disposed. One of the reflection members thereon defines a light source position and has a first reflecting surface. The other reflection member has a second reflecting surface toward the light source position, and a third reflecting surface, close to the second reflecting surface and toward the first reflecting surface. The first reflecting surface and the third reflecting surface form a light-out opening therebetween. Some light travels from the light source position to be reflected by the second reflecting surface and the first reflecting surface in order to emit out of the light-out opening. Some light travels from the light source position to be reflected by the third reflecting surface to emit out of the light-out opening.

Various embodiments disclosed herein include adaptive light source modules that can provide adaptive illumination to a scene. The adaptive light source modules may comprise a housing, an emitter array, and a lens. The emitter array comprises a plurality of emitters. The lens may redirect light emitted from the emitter array through a transparent window of the housing. The housing may further include a prismatic surface that distorts light emitted from the emitter array and/or one or more non-transparent portions that limits light travelling therethrough. The adaptive light source module may optionally comprise a light sensor, and a portion of the lens may be configured to direct light toward the light sensor.

A method for operating a light source for a camera, a light source and a camera are disclosed. In an embodiment the method for operating a light source for a camera comprises individually illuminating segments of the scene by the emitters, wherein an illumination parameter is determined for a segment of the scene and an emitter is individually driven on a basis of the illumination parameter, and wherein the illumination parameter is determined by a measurement of a physical variable and/or by an input of a user.

A low-glare fluorescent-powder LED light device includes a shell, a multi-frequency directional light source, a high-frequency directional light source, and an electrical control circuit. The shell has a surrounding wall, which defines a front opening and a rear opening and has an inner surface extending along a central axis. The multi-frequency directional light source, including at least one fluorescent-powder LED, is disposed at the inner surface of the shell. The high-frequency directional light source, including a plurality of high-frequency LEDs, is disposed at the inner surface of the shell such that the high-frequency LEDs are arranged in radial symmetry about the central axis. The electrical control circuit can drive the multi-frequency directional light source and/or the high-frequency directional light source. The central light beams emitting from the high-frequency LEDs do not reach the fluorescent-powder LED, so that the fluorescence interference of the fluorescent-powder LED can be avoided.

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 surveillance camera includes a first infrared irradiation portion that irradiates first infrared light, a second infrared irradiation portion that irradiates second infrared light having a narrower irradiation angle than the first infrared light, a camera body including an imaging lens for allowing light to be incident from an irradiation region of at least one of the first and second infrared lights, and a dome cover covering the camera body. The first infrared irradiation portion includes a first light source of the first infrared light and a first pedestal on which the first light source is placed. The second infrared irradiation portion includes a second light source of the second infrared light and a second pedestal on which the second light source is placed. 10 The first light and second sources, which are provided adjacent to a side surface of the camera body, are disposed differently in an up-down direction.
