Softbox

Abstract: The softbox has a locating bracket (31) for fixing the softbox at a spotlight such that the spotlight is translucence through the softbox in operation. A construction frame (29) is arranged for providing a light exit opening of the softbox. A light directing grid is arranged at the light exit opening for defining an exit angle of the light. The bracket has a blind hole (37) for receiving the construction frame. Multiple light gates (25, 27) are pivotable around a pivotable axis for limiting the spotlight in an operation mode. An independent claim is also included for a method for producing a light directing grid with translucent cells.

Abstract: The utility model relates to the technical field of photographic equipment, in particular to a plug-in LED (Light-Emitting Diode) studio light softbox. The plug-in LED studio light softbox comprises a baffle sleeve which is arranged on the outer side of a baffle of an LED studio light in a sleeving manner; the baffle sleeve surrounds the edge of the LED studio light to form a hollow structure; a light reflecting sleeve which is arranged on the baffle of the LED studio light in the sleeving manner is correspondingly arranged on the inner side of the baffle sleeve. According to the structures of the light reflecting sleeve and soft light cloth, the light reflecting area of light rays of the LED studio light is increased, so that the LED studio light has softer diffusion light and higher brightness, and the softbox is convenient to use, low in cost, and suitable for large-area popularization.

Abstract: The invention provides a light field scanning device. The device comprises a softbox, a turntable, a curved guide rail and a main control system; the softbox is laterally open; the turntable is horizontally disposed in the softbox; the turntable carries a scanned item and a three-dimensional mark reference object; the curved guide rail can be provided with a pan/tilt holder; the lens of a photographing device on the pan/tilt holder faces the turntable; the main control system controls the circuit system of a global light system, the turntable, the pan/tilt holder and the photographing device;and the generation system of the main control system receives and analyzes image data acquired by the photographing device. The present invention also provides a light field scanning method used for the above light field scanning device. According to the light field scanning device and the light field scanning method of the invention, a composite scanning technology, an image mapping technology, awhite light scanning technology and a photometric scanning technology are integrated, and therefore, almost all types of materials can be scanned; the three-dimensional geometric shape of the item can be scanned, at the same time, an ultra-high precision normal map, a diffuse reflection map, a global light map, a specular map and a depth map can be generated.

Abstract: Photographic light diffusion apparatus (softbox) comprises three or more panels (1,2,3,4) connected at major edges thereof so as to form a generally pyramidal enclosure having an apex (5) that is adapted to be mounted on a photographic lamp, and a base that is adapted to receive a light-modifying screen. Each panel (1,2,3,4) comprises a sheet of flexible material that is supported in tension by a flexible resilient hoop. The enclosure can therefore be very rapidly and easily collapsed and re-erected.
