Description

The present invention is concerned with an integrated LED bicycle lights and is designed as a lighting system for the bicycle. It has an internal power supply with a battery compartment, as well as an external power supply via a dynamo.

Currently, there are only lighting systems for two-wheelers, which must be externally installed on parts of the same. This has some disadvantages but also risks. A disadvantage is that the external light systems can be easily removed or stolen. Furthermore, they do not fit into a visually appealing image of the bicycle for the most part. Another drawback is that the external lighting systems can at worst get loose while driving due to material fatigue of the fixture.

One cause of the disadvantages is that they wear out easily due to the plastic fasteners. This results in the second disadvantage, namely that something that is attached, also easily removed, here the external lighting systems. The reason that external light systems are poorly integrated into the appearance of a two-wheeler is that manufacturers of one and the other do not cooperate with each other. An internal and integrated two-wheel light system is always visually inconspicuous and can only be stolen at great expense. Consequently, it requires no attachment in the traditional sense, because the individual components are integrated.

It is therefore an object of the present invention to provide a theft-proof, visually as inconspicuous and safe lighting system for two-wheelers, which meet the requirements of a bicycle lights.

This object is achieved with the characterizing features of the main claim. Further features of the invention are given in the dependent claims, as well as the description.

The integrated LED bicycle lights according to the invention is characterized by an improved view, which gives the driver more safety on the road, as well as by the low weight and the small footprint, which does not interfere with the bike, also caused no wind noise.

With this invention, a development of integrated bicycle lighting is presented. The basic idea was to develop a theft-proof and modern, as well as compact and lightweight lighting system. The goal was also to integrate the complete lighting system as well as the power supply in the bike.

The small space available and the components to be used are one of the main problems that have been solved. With only a few millimeters in diameter in the handlebar and in the seat post, there is little room for larger technical accessories, so you have to work with small and very powerful components. The integrated LED bike lights is a new development that is mainly used in racing applications, but also has its application in the field of normal recreational area.

By integrating at least one LED in the handlebar or in the seat post, neither the design nor the aerodynamics are disturbed. It also adapts to the aerodynamic shape of the bike. Good properties that can be achieved are the large beam angle and the enormous light output. Due to the specially developed battery compartment, changing the batteries is also very easy and problem-free.

The invention consists of a lighting system for bicycles that can be applied to almost any bicycle. Their main field of application is above all road bikes as well as new Custome wheels, because the lighting system does not interrupt the design line and is integrated into the carrier object.

Other features essential to the invention can be found in the dependent claims and the detailed description.

In the following the invention will be explained in more detail with reference to drawings. It shows:

1 : the front view of a handlebar ( 2 ) with two LED lights ( 3 . 3 ' );

2 : an exploded view of a battery compartment ( 4 );

The 2 shows an exploded view of a battery compartment 4 in a handlebar 2 , The battery compartment in the handlebar had to be developed independently, as there was no such battery compartment on the market. The difficulties with the battery compartment were the small space of only a few millimeters inside diameter of the handlebar tube, as well as the resilience of shocks and vibrations. The presented in this invention variant of the power supply via a specially manufactured battery compartment 4 , This is small enough to fit into the above mentioned carrier objects. The battery compartment consists of a tube that is large enough in circumference, diameter and length to accommodate the intended power sources but at the same time small enough to be mounted in the carrier objects. The tube is open to one side. Through this opening can be the power source 9 feed the battery compartment, in order then to be able to screw in the cathode part (metal screw) through an internal thread. Bottom side is the anode part of the battery compartment. The cathode is set by screwing the aforementioned screw, which is electrically conductive, into the open side of the tube. As a result, a current flow between negative pole via the forward and return conductors to the positive pole. It should be noted that the tube is insulated from the outside, ie towards the carrier object. So it can lead to no short circuit and thus no destruction of the system. As power sources, rechargeable batteries as well as conventional batteries can be used. For the connection or disconnection of the current flow to the consumer (LED's) different types of switches can be installed. This patent introduces the key switch, toggle switch and push button switch.

The components of the battery compartment 4 are made of plastic and aluminum, which offers space for 2 × AAA, which, connected in series, give a voltage of 3V.
