Abstract
Description
Videoleuchten für die Videokamera bestehen aus einem Gehäuse in das eine Glühbirne angebracht ist. Eine Linse oder Reflektor sind Bestandteil der Videoleuchte. Das Licht muss das gesamte Video-Feld gleichmässig und stark beleuchten. Video lights for the video camera consist of a housing in the a light bulb is attached. A lens or reflector are part of it the video light. The light must be even across the entire video field and illuminate strongly.
Diese Art von Videoleuchten sind ziemlich klein und weisen eine grosse Leuchtstärke auf. Der Nachteil ist, dass sie sehr viel Strom verbrauchen. Das führt zu verkürzten Videoaufnahme-Zeiten, die abhängig von der Akku-Kapazität sind. These types of video lights are quite small and have a large one Luminosity on. The disadvantage is that they consume a lot of electricity. This leads to shorter video recording times, which depend on the Battery capacity are.
Der in den Patentansprüchen 1 bis 21 angegebenen Erfindung, liegt das Problem zugrunde eine Videoleuchte zu schaffen, die ein gleichmässiges, helles Licht bei geringer Energie-Verbrauch abgibt. The invention specified in claims 1 to 21, that is Problem to create a video light that has a uniform, emits bright light with low energy consumption.
Dieses Problem wird mit den in den Patentansprüchen 1 bis 21 aufgeführten Merkmalen gelöst. This problem is solved with the in claims 1 to 21 Features listed solved.
Mit der Erfindung wird eine längere und hellere Beleuchtung bei geringeren Energie-Verbrauch für die Videokameras erreicht. Der Lichtspektrum dieser Videoleuchte ist sehr ähnlich mit dem Tageslicht- Spektrum und daher treten keine Farbverfälschungen während Videoaufnahmen auf. With the invention, a longer and brighter lighting achieved lower energy consumption for the video cameras. The Light spectrum of this video light is very similar to the daylight Spectrum and therefore no color distortions occur during Video recordings.
Ausführungsbeispiele der Erfindung werden anhand der Fig. 1 bis 3 erläutert. Es zeigen: Embodiments of the invention are explained with reference to FIGS. 1 to 3. Show it:
Fig. 1 eine einfache Variante dieser Videoleuchte, FIG. 1 shows a simple variant of this video light,
Fig. 2 eine Variante mit facettenartige Anordnung der Leuchtdioden, Fig. 2 shows a variant with facet-like arrangement of the light-emitting diodes,
Fig. 3 die Abdeckscheibe mit linsenartigen Verformungen. Fig. 3, the cover plate with lens-like deformations.
Diese Videoleuchte 1 besteht aus mindestens einer weissen Leuchtdiode 2. Eine Variante besteht aus mehrere Leuchtdioden, die verschiedene Lichtstrahlen abgeben, dessen gesamtes Lichtstrahl aber weiss ist. Die weissen Leuchtdioden spenden eine helles Licht und verbrauchen sehr wenig Energie. Optimale Ergebnisse werden mit mehrere Leuchtdioden erzielt. Z. B. 40-100 Leuchtdioden, können ein sehr intensives Licht spenden. Die Akku 3 hält auf jedem Fall länger als bei der herkömmlichen Glühbirnen bei gleicher Licht-Leistung. Das Licht dieser Videoleuchte kommt dem Lichtspektrum der Sonne näher und verfälscht daher die Farben während der Videoaufnahme nicht. Ein Regler 4 sorgt dafür, dass diese Videoleuchte ein optimal geregelte Lichtleistung abgibt. This video light 1 consists of at least one white light-emitting diode 2 . A variant consists of several light emitting diodes that emit different light beams, but the entire light beam is white. The white light emitting diodes provide a bright light and use very little energy. Optimal results are achieved with several LEDs. For example, 40-100 LEDs can emit a very intense light. The battery 3 definitely lasts longer than with conventional light bulbs with the same light output. The light of this video light comes closer to the light spectrum of the sun and therefore does not distort the colors during the video recording. A controller 4 ensures that this video light emits an optimally regulated light output.
Die weissen Leuchtdioden strahlen in der Regel ein nicht so stark gebündeltes Licht aus. Das Bündeln des Lichts wird mittels eines Mini- Reflektors 5 und/oder einer Linse 6 vor der Leuchtdiode erreicht. Eine Abdeckscheibe 7 mit linsenartigen Verformungen 8 kann behilflich sein. Es reicht nur eine Abdeckscheibe aus, die viele solche Verformungen aufweist. Die linsenartigen Verformungen sollen jeweils exakt vor den Lichtstrahl jeder Leuchtdiode angeordnet werden. Nur so kann ein gebündelter Lichtstrahl erzeugt werden The white light-emitting diodes usually emit light that is not so strongly focused. The bundling of the light is achieved by means of a mini reflector 5 and / or a lens 6 in front of the light-emitting diode. A cover plate 7 with lens-like deformations 8 can be helpful. All that is needed is a cover plate with many such deformations. The lens-like deformations should be arranged exactly in front of the light beam of each light emitting diode. This is the only way to generate a bundled light beam
