Object of the invention

task The invention is a very simple and inexpensive lighting device for use on a body to provide that is at least inexpensive to produce.

Solution of the task

The solution The object is to provide a lighting device, the a main body and on the body mounted light-emitting diodes comprises, wherein the main body in Essentially consists of a flexible printed circuit board.

Of the The basic idea of the flexible printed circuit board is that the Known from the prior art headband, where the light source is attached, completely eliminated. This can be very cost effective and in a very simple way a head lamp or even a lighting device that attach to any body is to be produced. The flexible circuit board is on the post Outside side unprinted. This means that enough space is available is, for example, advertising or similar other prints, ornaments or similar to install. On the inside, that means on the body facing Side, the traces are mounted on the printed circuit board. The simplified arrangement of printed circuit boards provides that the bulbs are connected in series, so via a single switch a on and off function is guaranteed.

At the free end of the movable and flexible circuit board is a Fastener, preferably in the execution of a hook and loop fastener intended. Thus, for example, a round body can be included, wherein then the free ends over the Velcro fastened together. In this way and Way is also an attachment to a user's head possible.

The flexible printed circuit board has a high degree of flexibility, so that angle changes over 100 ° are possible. The PCB itself is also tiltable in stripes, so a very cost cheap series production is possible.

The Attachment of the light-emitting diodes via the so-called SMD technology. Here can for example in a solder bath the LED are mounted. Alternatively, it is also possible, for example by home work or in workshops for the disabled very cost-effective Light emitting diodes with the printed circuit boards to konektieren via a solder joint.

The Light diodes themselves are designed very flat and almost form with the on the trace repellent side of the PCB one Level. The LEDs have a flat small lens, the Focused emits the emitting light. This avoids that immediately adjacent persons are disturbed by this light.

As soon as the corresponding light emitting diodes on the flexible printed circuit board are arranged, it is possible to the body to cushion facing side. Here is a simple sealing tape or upholstery tape with a one-sided adhesive immediately the printed circuit board or conductor track are applied.

The Power cable used to power the LEDs and for the connection is necessary to power, is also connected to the tracks soldered. The cable can be designed as long as desired and directly with a Akkublock be konektiert.

A alternative embodiment provides that the light intensity additionally is adjustable. As a result, also corresponding dimming effect can be achieved. A simple potentiometer is enough between the power supply and the Leucthmitteln is arranged to the appropriate effect too achieve.

A sees another alternative embodiment to design the light-emitting diodes in color. This has particular choreographic effect. If the LEDs are red, then the Glare further reduced. Especially in the night vision area then a lighting device has been created, the very punctual and illuminates space in the immediate field of vision.

A still another embodiment provides that in addition Switching elements are provided which the light-emitting diodes as light strip let act, so in turn one or the other LED is switched on and off. This creates a running light function, which may be indicative of a particular device, but also exercise warning function can.

A Another alternative is small-sized solar cell elements to install on the side facing away from the conductor track of the printed circuit board. This can be a supply over an external power supply will at least be reduced, if not Completely be omitted.

The invention Lighting device is particularly suitable for reading at night in bed because the bed neighbor thereby not by the wide stray field of the bulb molested becomes.

A other embodiment may provide that, for example, a choir such lighting devices wearing in the head area and thus achieves a choreographic effect (in addition to the actual intended use, To be able to read notes even in darkness).

Of the essential advantage of the invention is that in a very cost effective manner and in mass production, the lighting device can be achieved.

she can be equipped with a disposable battery, so for example at fireworks festivals or other events the lighting device at certain stands can be sold at a price that equals a "disposable item".

moreover the lighting device provides sufficient space to appropriate To place advertising.

Further advantageous embodiments will become apparent from the following description, the drawings and the claims out.
