Abstract

The camera flash light (1) consists of at least one visible intensive white light emitting diode or LED (2) as a light source. It can have several LEDs emitting different colors that produce an almost white light in combination. The LEDs are arranged close together to emit light in parallel directions. The LEDs can be arranged in a facet formation.

Description

Blitzgeräte für die Kamera bestehen aus einem Gehäuse in das eine Blitzröhre angebracht ist. Eine Linse oder Reflektor sind Bestandteil der Blitzleuchte. Das Licht muss das gesamte Kamera-Feld gleichmässig und stark beleuchten. Flash units for the camera consist of a housing in one Flash tube is attached. A lens or reflector are part of the Strobe light. The light must be even and uniform throughout the camera field illuminate strongly.

Diese Art von Blitze sind ziemlich klein und weisen eine grosse Leuchtstärke auf. Der Nachteil ist, dass sie sehr viel Strom verbrauchen. Das führt zu verkürzten Aufnahme-Zeiten, die abhängig von der Akku- Kapazität sind. These types of flashes are quite small and have a large one Luminosity on. The disadvantage is that they consume a lot of electricity. This leads to shorter recording times, which depend on the battery Capacity are.

Der in den Patentansprüchen 1 bis 23 angegebenen Erfindung, liegt das Problem zugrunde einen Lichtgeber zu schaffen, der ein gleichmässiges, helles Licht bei geringer Energie-Verbrauch abgibt. The invention specified in claims 1 to 23, that is Problem to create a light transmitter that has a uniform, emits bright light with low energy consumption.

Dieses Problem wird mit den in den Patentansprüchen 1 bis 23 aufgeführten Merkmalen gelöst. This problem is solved with that in claims 1 to 23 Features listed solved.

Mit der Erfindung wird eine längere und hellere Beleuchtung bei geringeren Energie-Verbrauch für die Kameras erreicht. Der Lichtspektrum dieser Kameraleuchte ist sehr ähnlich mit dem Tageslicht-Spektrum und daher treten keine Farbverfälschungen während Aufnahmen auf. With the invention, a longer and brighter lighting lower energy consumption for the cameras. The light spectrum this camera light is very similar to the daylight spectrum and therefore there are no color distortions during 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 Kameraleuchte, FIG. 1 shows a simple variant of this camera light,

Fig. 2 eine Variante mit facettenartige Anordnung der Leuchtdioden, Fig. 2 shows a variant with facet-like arrangement of the light-emitting diodes,

Diese Kameraleuchte 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 Kameraleuchte kommt dem Lichtspektrum der Sonne näher und verfälscht daher die Farben während der Aufnahme nicht. Ein Regler 4 sorgt dafür, dass diese Leuchtkörper ein optimal geregelte Lichtleistung abgibt. This camera 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 from this camera light comes closer to the light spectrum of the sun and therefore does not distort the colors during the shot. A controller 4 ensures that this luminous element 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.

Mit diesem Leuchtkörper können Digital-Bildkameras sowie die herkömmlichen Bild-Kameras ausgestattet werden. In diesem Fall wird kein Blitzgerät benötigt. Die Beleuchtung kann im Blitzlicht- oder Dauerlicht-Modus eingeschaltet werden. With this filament, digital cameras as well as the conventional image cameras. In this case no flash unit needed. The lighting can be in the flash or Continuous light mode can be switched on.
