Videokamera mit integrierten BeleuchtungVideo camera with integrated lighting

Videoleuchten üblicher Art bestehen aus einem Gehäuse, einem Reflektor und einer Glühbirne. Die sind in die Videokamera integriert oder abnehmbar angebracht. Diese Videoleuchten spenden eine helles Licht und sind ziemlich intensiv. Ein grosser Nachteil ist, dass sie sehr schnell den Akku der Videokamera verbrauchen.Video lights of the usual type consist of a housing, a reflector and a light bulb. These are integrated into the video camera or can be removed. These video lights provide a bright light and are quite intense. A big disadvantage is that they use up the video camera's battery very quickly.

Der in den Schutzansprüchen 1 bis 24 angegebenen Erfindung liegt das Problem zugrunde, eine Videokamera mit einer leuchtstarken Videoleuchte zu schaffen, die sehr sparsam ist und kleine Abmessungen hat.The invention specified in claims 1 to 24 is based on the problem of creating a video camera with a bright video light which is very economical and has small dimensions.

Dieses Problem wird mit den in den Schutzansprüchen 1 bis 24 aufgeführten Merkmalen gelöst.This problem is solved by the features set out in claims 1 to 24.

Ausführungsbeispiele der Erfindung werden anhand der Fig. 1 und 2 erläutert. Es zeigen:Embodiments of the invention are explained with reference to Figs. 1 and 2. They show:

Fig. 1 eine Videoleuchte, die mit mehreren LED-s bestückt ist, Fig. 2 eine Anwendungs-Möglichkeit dieser Videoleuchte,Fig. 1 a video light equipped with several LEDs, Fig. 2 a possible application of this video light,

Die Leuchtdioden sind paarweise in Reihe angeschlossen. Dadurch ist die Spannung und Strom optimal für die LED-s und somit ein Strombegrenzer überflüssig.The LEDs are connected in pairs in series. This means that the voltage and current are optimal for the LEDs and a current limiter is therefore unnecessary.

Vorteile der Erfindung sind:Advantages of the invention are:

- diese Videoleuchte, bzw. der &ldquor;Kopf kann an verschieden Stellen und Geräten angebracht werden wie z.B. Fahrräder, Inline-Scates, Alu-Roller, Kinderwagen, Behinderten-Rollstuhl, Schlittschuhen, Rollschuhe, Sport-Schuhe, Ski-Schuhe, Schlitten, als Leseleuchte für Fahrzeuge etc.- this video light, or the "head" can be attached to various places and devices such as bicycles, inline skates, aluminum scooters, strollers, disabled wheelchairs, ice skates, roller skates, sports shoes, ski boots, sledges, as a reading light for vehicles, etc.

- sie ist sehr klein und sehr intensiv leuchtend,- it is very small and very intensely luminous,

- im Sparmodus kann sie, je nach Ausführung und Akku-Kapazität, bis zu eine Woche oder länger ununterbrochen leuchten.- In economy mode, it can shine continuously for up to a week or longer, depending on the model and battery capacity.

Diese Videokamera 1 ist sehr einfach gebaut. Sie weist mehrere Leuchtdioden 2 auf. Diese sind in zwei Reihen parallel eingeschaltet. Die zwei LED-Reihen sind ebenfalls in Reihe angeschlossen. Das ergibt pro LED eine Spannung von ca. 4,5 V. Je nach gewünschter Leuchtintensität, kann ein Vorwiderstand für die LED-s eingebaut werden. Es reicht im Prinzip ein Widerstand, die eine Leistung von etwa 0,2 W bis 2 oder 3 W hat.This video camera 1 is very simply constructed. It has several light-emitting diodes 2. These are connected in parallel in two rows. The two rows of LEDs are also connected in series. This results in a voltage of approx. 4.5 V per LED. Depending on the desired light intensity, a series resistor can be installed for the LEDs. In principle, a resistor with an output of approx. 0.2 W to 2 or 3 W is sufficient.

Das Anbringen in verschiedene Geräte kann sehr einfach gemacht werden. Diese Videoleuchte kann ein eingebautes 9-V-Batterie-Andockstelle 3 oder 9-V-Batterieclip aufweisen. Sie wird einfach an eine 9V-Blockbatterie angedockt.Attaching it to different devices can be done very easily. This video light can have a built-in 9V battery docking station 3 or 9V battery clip. It is simply docked to a 9V block battery.
