Description

The invention relates to a string of lights with a large spectrum of light, in particular a string of lights with a large spectrum of light in a lighting system whose luminous spectrum is not limited.

With the advances in science and technology, LED has become widely used in lighting systems thanks to its higher brightness, small volume, energy savings and longer service life.

The range of use of LEDs extends from lighting systems or displays such as street lighting, table lamps, hand lamps, traffic lights, direction indicators and brake lights, etc. on decorative lamps such as Christmas lights. The decorative lamps are usually designed as an elongated string of lights, which is formed by attaching several LEDs to a power line at a certain distance. Users can wrap or hang the fairy lights on the object to be decorated. By different light colors of LEDs, the decorative effect is realized.

From the TW 581188 discloses a parallel-connected string of lights having a first line, a second line and a plurality of lighting elements. The first and the second line are parallel to each other. The light-emitting elements each have a first and a second electrode, which are located on opposite end portions of the corresponding light-emitting element. The first electrode is electrically mounted on the first lead. The second electrode, however, is electrically connected to the second line. In addition, all lighting elements are packed in a transparent insulating plastic, such that the lighting elements are shielded from the outside.

From the US7235815 is another LED string of lights known, which mainly has two lines. The one line is previously processed to a platform for receiving LEDs. The LEDs are each connected to the two wires by two conductive wires, which energize the LEDs.

• 1. Die Lichtstrahlen von der Anschlussfläche der LEDs werden völlig bedeckt, derart, dass das Leuchtspektrum von LEDs beschränkt wird. Mit einem anderen Wort können LEDs in diesem Fall lediglich einen bestimmten Bereich leuchten.
• 2. Da die Lichtstrahlen bedeckt sind, kann die beim Leuchten erzeugte Wärme nicht abgeführt werden, was eine Sammlung von Abwärme zur Folge hat. Dies führt zu einer kürzeren Gebrauchszeit von LEDs.
• 3. Werden die Leitungen gebogen bzw. gefaltet, dann liegen die gebogenen bzw. die gefalteten Leitungen auf LEDs. Aus diesem Grund ist keine optimale Wirkung durchs Biegen bzw. Falten zu realisieren. Von daher können die vorstehenden Lichterketten nicht in allen zu dekorierenden Objekten verwendet werden.
• 4. Die Verarbeitung von Leitungen in mehrere Plattformen verlängert die Herstellungszeit, wodurch die Herstellungseffizienz beeinträchtigt wird.

The above LED fairy lights are subject to the following problems due to the arrangement of LEDs on a line:

• 1. The light rays from the pad of the LEDs are completely covered, such that the light spectrum of LEDs is limited. In other words, LEDs can only light up a certain area in this case.
• 2. Since the light rays are covered, the heat generated during lighting can not be dissipated, resulting in a collection of waste heat. This leads to a shorter period of use of LEDs.
• 3. If the lines are bent or folded, then the bent or folded lines lie on LEDs. For this reason, no optimum effect is to be realized by bending or folding. Therefore, the above fairy lights can not be used in all the objects to be decorated.
• 4. Processing lines into multiple platforms increases manufacturing time, which affects manufacturing efficiency.

The invention is therefore an object of the invention to provide a fairy lights, with the above problems of conventional fairy lights such as insufficient light spectrum and poor heat dissipation can be solved.

This object is achieved by a fairy lights with a large luminous spectrum, which has the features specified in claim 1. Further advantageous developments of the invention will become apparent from the dependent claims.

The invention provides a light chain with a large spectrum of light having a first, a second line and at least one luminous element. The first and the second line are parallel to each other. Between the first and the second line, the light-emitting element is arranged. The light emitting element is provided with first and second conductive wires for electrically connecting to the first and second leads. In addition, the light-emitting element is wrapped in a capsule having an insulation support layer and an insulation cover layer. The insulating support layer serves to support the luminous element. The Isolationsabdeckschicht is connected to the Isolationstragschicht and is thus placed on the light-emitting element. The insulation support layer and the insulation cover layer of the capsule are translucent.

In embodiments of the invention, the luminous element is designed as a LED cube with double or single electrode. Alternatively, the luminous element may also be designed as an SMD LED. With the insulation cover layer and the insulation support layer, the first and second conductive wires and the first and second leads are clad. In addition, the insulation support layer and the insulation cover layer are integrally assembled in a tool. The insulating support layer is designed as a transparent membrane plate, while the Isolationsabdeckschicht as Packaging is placed on the insulation backing layer.

The construction according to the invention ensures a large luminous spectrum in that the angle of illumination is not restricted by the lines. In addition, the waste heat generated during lighting can be completely dissipated, whereby the collection of waste heat is excluded. In addition, the two lines do not need to be extra processed, thereby reducing the manufacturing time much.
