摘要： The invention relates to a method for the temperature-dependent adjustment of the color or photometric properties of an LED illumination device having LEDs or LED color groups emitting light of different colors or wavelengths, emitting light of the same color or wavelength within a color group, the luminous flux portion thereof determining the light color, color temperature, and/or the color location of the light mixture emitted by the LED illumination device, characterized by measurement of the board temperature and/or junction temperature of at least one LED, determination of at least one temperature-dependent value determining the emission spectra E(λ) of the variously colored LEDs as a function of the wavelength of the variously colored LEDs from calibration data stored for each of the variously colored LEDs, determination of the luminous flux portions of the variously colored LEDs for a light mixture comprising a prescribed light color, color temperature, and/or color location at the measured temperature as a function of the at least one temperature-dependent value determined, and adjustment of the determined luminous flux portions at the variously colored LEDs.

摘要： In a method and a device for driving light-emitting diodes (11) (LEDs) of an illumination device (10), in particular an illumination device for film, video and photographic recordings with a pulse width modulation of the light-emitting diode current, the pulse-width-modulated light-emitting diode current IPWM is detected, a current measurement value IM is amplified and, by means of a root-mean-square value converter (8), a current sensor signal ls is derived, digitized and fed as a value ADval of the digitized current sensor signals ls to a microprocessor (3), which outputs a drive signal both for the pulse width modulation and for the setting of the light-emitting diode voltage applied to the light-emitting diodes (11), depending on the detected current measurement value IM.

摘要： Disclosed is a device for soundproofing motion picture cameras, featuring soundproof support of the camera frame (2) which supports the noise-generating parts of the camera mechanism, embodies an image plane for the moving film (F), and is located in a camera housing (1). The camera housing (1) is provided with a lens support (10) which is disposed in the recording beam path (A) of the motion picture camera and to which an optical recording element can be fastened. The inventive device comprises two top connecting elements (4, 5) that are placed above and on both sides of the image center (B) in the front area of the motion picture camera as well as a bottom connecting element (6) which is positioned below the image center (B) in the front area of the motion picture camera. The camera frame (2) is suspended on the camera housing (1) via said connecting elements (4, 5, 6). The connecting elements (4, 5, 6) are composed of buffer elements (41, 42, 51, 52, 61, 62), which are preferably made of a polyurethane elastomer, and a pin (7) or screw (8) that is inserted through the buffer elements (41, 42, 51, 52, 61, 62) and connects the buffer elements (41, 42, 51, 52, 61, 62) to the camera housing (1) and the camera frame (2).

摘要： The invention relates to a dielectric barrier discharge lamp with a fluorescent mixture and improved colour reproduction. The fluorescent mixture comprises at least the fluorescent components: A) cerium-activated yttrium aluminate (Y3AI5O12:Ce) and B) europium-activated barium magnesium aluminate (BaMgAI10O17:Eu). To further improve the colour reproduction and to match the emission spectrum to the film sensitivity the fluorescent mixture optionally comprises the additional fluorescent components: C) cerium- and manganese-activated gadolinium magnesium zinc pentaborate (Gd(Zn,Mg)B5O10:(Ce, Mn)) and/or the fluorescent component D) europium-activated strontium aluminate (Sr4AI14O25:Eu).

摘要： The invention relates to a film guide for a film camera, comprising an image aperture (4) arranged in the recording beam path of the film camera, and a distance window (6) arranged on a grip plate (5). The film is guided, by means of a film transporting mechanism, through a film channel or film gap embodied between the facing film planes. The grip plate (5) and/or the distance window (6) are supported on the image aperture (4) by means of projections (51, 52, 53 or 61, 62, 63).

摘要： The invention relates to a method for automatically correcting frame faults contained in video assist frames of a video assist system (2, 3) in a video optical path that has been diverted from a capture optical path of a motion-picture camera, said video optical path being provided with a focusing screen. To calibrate the video assist system (2, 3), at least one video assist frame of a monotone, unstructured, uniformly illuminated, flat object is captured using a predefined aperture of the camera lens (10) and is stored as a video assist calibration frame in a frame store, said calibration frame being superimposed on the video assist frames that have been captured after the calibration as an inverted video assist calibration frame.
