DE202009011954U1 - 3 volt LED light - Google Patents

Abstract

LED light, characterized in that the light fixtures in the form of a cap having openings for the light emission, board with LEDs, short circuit, round 1.5 volt batteries and heavily discharged 9 volt block has.

Description

There are LED light with white LED known, which are designed as an attachment to 9 volt block (PAK-LITE Flashlight, US Pat. No. 6,511,202 B1 IPC F2L 4/00, or flashlight, DPMA 20 2007 001 995.5).

According to the Invention 20 2007 001 995.5 the lamp includes a holder, where light module is plugged in and then 9 volts Block is pushed in.

Turn off is done by reversing the polarity of the battery - there is no switch available.

The Light is cheap, robust and easy to manufacture.

• – Kompatibilitätsproblem zwischen Batteriespannung 9 Volt und benötigten für weiße LED 3,x Volt,
• – keine Möglichkeit Lampe zu dimmen,
• – relativ teuere Block-Batterien.

Disadvantages of known luminaires are:

• - Compatibility problem between battery voltage 9 volts and needed for white LED 3, x volts,
• - no way to dim lamp,
• - relatively expensive block batteries.

at The 9 volt light will solve the problem by connecting several in series LED's solved what in case of failure of one LED, others intact makes us unusable.

aim our invention is the creation of an LED luminaire, firstly - compatible to available voltage is, secondly - of cheap round 1.5 volt batteries benefits, higher redundancy (in case of failure of the LED's), third - also of Heavily discharged 9 volt blocks could be fed, fourth - light dimmable.

• – die leistungsfähigere LED's verwendet werden, die auch bei niedrigerer als 3 Volt Spannung akzeptable Menge von Licht erzeugen,
• – die Leuchte parallel geschaltete LED's aufweist,
• – schon bekannte (für 9 Volt Leuchte) Halterung wird aus Thermoplastik ausgeführt (was lässt die Halterung bei Temperatur um etwa 95 Grad. C mit einigen Handgriffen leicht verformen und bei weiterem Abkühlen erstarren), so dass bekannte Halterung (jedes Mal verformt) entweder für 9 Volt Blocks oder für zwei runde AA-Batterien (die an der Stirnseite „+” und „–„ Kontakte aufweisen) Platz bietet.
• – im Unterschied zu 9 Volt Block, bei zwei runden Batterien sollten noch PLUS und MINUS Kontakte zusammengeschlossen werden (Reihenschaltung). Das wird durch Aufziehen schon bekannter Halterung (zweite Halterung) mit elektrisch leitenden Einlage an der Hinterseite gewährleistet.

This problem is solved by that

• - the more powerful LED's are used, which produce an acceptable amount of light even at voltages lower than 3 volts,
• The lamp has LEDs in parallel,
• - Already known (for 9 volt lamp) mount is made of thermoplastic (which makes the bracket at about 95 degrees C. temperature slightly deform with a few simple steps and solidify on further cooling), so that known holder (deformed each time) either for 9 volt blocks or for two round AA batteries (which have "+" and "-" contacts on the front).
• - in contrast to 9 volt block, with two round batteries should still PLUS and MINUS contacts are connected together (series connection). This is ensured by mounting already known holder (second holder) with electrically conductive insert at the rear.

When second variant offers a conductive terminal, the stop and contact for two antiparallel running round batteries by simple Mounting allows.

at o. g. Arrangement is also by using a voltage converter (1.5 volts to 3, x volts) in the shape and dimensions of a round AA battery It is also possible to supply the lamp with a 1.5 volt battery only.

In In this case, for contacting a specially developed Adapter can be used.

• – verschiedene Lichtströme zu erzeugen,
• – allmählich sinkende Spannung von 9 Volt Block durch überbrücken von einzelnen LED optimal auszubeuten,
• – bei Bedarf farbiges oder blinkendes Licht zu erzeugen.

In protection claims 4, 5, 6, 7, 8 specified properties of the lamp allow by reversing the battery pack:

• To generate different luminous fluxes,
• - optimally exploit gradually decreasing voltage of 9 volts block by bridging individual LEDs,
• - to produce colored or flashing light if required.
