The present invention relates to a lighting device comprising: a light emitter; a diffuser; one or more lenses located between the light emitter and the diffuser; and a control unit; wherein the control unit is capable of adjusting the properties of the diffuser. The present invention also relates to a lighting system comprising one or more such lighting devices, preferably wherein each of the lighting devices is arranged to be controlled using a single master control unit. The present invention also relates to a computer program product for operating such a lighting device or lighting system.

A lighting unit, configured and adapted for illuminating subjects for photography and filming, has a connecting element that comprises, on the one hand, plug-in locations configured and adapted to receive at least two light sources, and, on the other hand, contacts configured and adapted to be connected to a generator, the contacts being electrically connected to the plug-in locations. At least two light sources are inserted into the plug-in locations. A substantially transparent protective cover is connected to the connecting element and at least partially encloses each of the light sources connected to the connecting element. One light source is designed as an HMI (Hydrargyrum Medium-Arc Iodide) light and the at least one other light source is designed as a flash tube. A lighting device including a lighting unit, and a reflector assembly with a lighting device, are also disclosed.

A lightweight housing with a mount that can be attached to a user, sports equipment, or vehicle contains an illumination assembly but no camera. The illumination assembly may communicate via Bluetooth with a similarly-configured nearby camera module to provide illumination for subjects being imaged by the camera module.

A direct-lighting mode and soft-lighting mode interchangeable photography LED illuminating lamp. The present invention solves an inconvenience that a camera photographer has to carry a direct-lighting LED illuminating lamp and a soft-lighting LED illuminating lamp both, and there is no such LED illuminating lamp currently. The essence of the technical solution includes: a lamp casing, a plurality of LED lights, a power supply connector, a power supply switch, a stand, and a luminescence window provided at the front face of the lamp casing, wherein the lamp casing is provided with a plurality of first LED lights at its front face thereof opposite to the inner side of the luminescence window, with the radiation directions of the first LED lights being toward the front of the LED illuminating lamp; the lamp casing is further provided with a plurality of second LED lights at its inner circumferential faces opposite to the inner side of the luminescence window; the lamp casing is provided with a transparent light guide plate for covering the luminescence window which is positioned opposite to the inner side of the luminescence window, with the radiation directions of the second LED lights being toward the outer circumferential faces of the transparent light guide plate respectively; the inward surface of the transparent light guide plate facing the first LED lights is provided with light ray reflection dents; and the lamp casing is further provided with an illumination mode toggle switch.

The invention provides a remote flashgun incorporating a xenon flash bulb for use with a mobile device comprising an internal camera that enables the user to take improved photographs in low light conditions. A plastic case is used to hold the flashgun and mobile device in close proximity. An application running on the mobile device communicates with the flashgun to provide information on the required total flash light output and timing to synchronize with the mobile device capturing an image or photograph.

The invention further enables the user to take photographs of high speed events, such as a balloon bursting. The flashgun is configured with an integrated microphone to provide a trigger signal to operate the xenon bulb at a time suitable to illuminate the high speed event. The application operates the camera to take continuous images and captures the image when the flash bulb was operated.

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 accessory includes a plurality of communication contacts that includes a first contact, and a control unit that notifies an electronic apparatus of a communication request by changing a signal level of the first contact from a first signal level to a second signal level different from the first signal level, and transmits information indicating a communication factor in response to a reception of a request for the information indicating the communication factor in response to a notification of the communication request. In a case where the control unit notifies the electronic apparatus of the communication request via the first contact in response to a start of a power supply, the control unit performs predetermined communication without receiving the request for the information indicating the communication factor or transmitting the information indicating the communication factor.

A lightweight housing with a mount that can be attached to a user, sports equipment, or vehicle contains an illumination assembly but no camera. The illumination assembly may communicate via Bluetooth with a similarly-configured nearby camera module to provide illumination for subjects being imaged by the camera module.

An illumination system includes: an irradiation device that irradiates light to a subject located in front of a displayer that displays a background image; an information acquisition device that acquires subject information for identifying the subject; a storage that stores background image information on the background image displayed on the displayer; and a controller that controls irradiation by the irradiation device. The controller generates shape information of the subject on basis of a difference between the subject information acquired by the information acquisition device and the background image information stored in the storage, and sets an irradiation range where light is irradiated by the irradiation device on basis of the shape information.

A stable inspection tool and method for inspecting electrical manhole vaults and other structures. The tool and method of the present invention eliminates the need for physical entry into underground electrical manhole vaults and other underground structures when inspecting the structure or when identifying, tracing and mapping existing conductor and conduit locations. Further, improved images of the structure may be obtained without entering the structure.
