Description

a string of lights

technical field

The utility model relates to lighting technology, in particular to a lamp string.

Background technique

Light strings are widely used in decorative lighting and are one of the ubiquitous items in people's daily life. When the night falls, all kinds of light strings emit colorful lights, which can have a strong foil and decorative effect on the surrounding environment. Please refer to Figure 1, a linear light string commonly used at present mainly includes a plug 1 that can be directly connected to an AC power supply, and a plurality of sub-light strings are connected in parallel through wires between the positive and negative poles of the plug 1 (in Figure 1 only Draw two sub-light strings A and B), the first sub-light string A is connected in series by a plurality of lamp heads from A1 to An through wires, and the second sub-light string B is connected in series by a plurality of lamp heads from B1 to Bn through wires , the plug 1, the first sub-light string A and the second sub-light string B are arranged in a straight line, and the first lamp head A1 of the first sub-light string A is closest to the plug 1, followed by A2 to An, B1 to Bn, the first lamp cap A1 of the first sub-light string A is respectively connected to the anode of plug 1 and the first lamp cap B1 of the second sub-light string B, and the last lamp cap An of the first sub-light string A is respectively connected to plug 1 The negative pole of the second lamp string B is connected to the last lamp cap Bn. It can be seen from the figure that the distance between the lamp cap A1 and the lamp cap B1 is very long, so the wire connecting the lamp cap A1 and the lamp cap B1 is also very long. Similarly, the lead connecting the lamp cap An and the lamp cap Bn, and the lead connecting the lamp cap An and the negative pole of the plug 1 are all very long, which greatly increases the production cost. Therefore, many manufacturers are trying their best to launch light strings with low cost, simple structure and better use effect to occupy the market.

Utility model content

Aiming at the shortcomings of the prior art, the purpose of the utility model is to provide a light string, which solves the problem that the connecting wires of the current linear light string are too long.

In order to achieve the above purpose, the technical solution of the utility model is: a light string, including a plug that can be directly connected to the AC power supply, and a plurality of sub-light strings are connected in parallel through wires between the positive and negative poles of the plug, and each sub-light string A plurality of lamp caps are connected in series through wires, and in each sub-lamp string, the last lamp cap in series relationship is the closest to the plug, and the penultimate lamp cap is the farthest from the plug.

The sub-light strings include a first sub-light string and a second sub-light string. The lamp heads of the first sub-light string and the second sub-light string are respectively arranged in a straight line and located on both sides of the plug.

The first lamp cap of the first sub-light string is respectively connected to the positive pole of the plug and the first lamp cap of the second sub-light string, and the last lamp cap of the first sub-light string is respectively connected to the negative pole of the plug and the first lamp cap of the second sub-light string. the last lamp head connected.

The first lamp cap of the first sub-light string is respectively connected to the positive pole of the plug and the first lamp cap of the second sub-light string, the last lamp cap of the first sub-light string is connected to the negative pole of the plug, and the second sub-light string The last lamp head of the plug is connected to the negative pole of the plug.

The distance from the last lamp head of each sub-light string in series relationship to the plug is the same, and the first sub-light string, the second sub-light string, the plug and the wires connecting them are combined to form a "Y" shape.

Compared with the prior art, among the sub-light strings of the light string of the present utility model, the last lamp head in the series relationship is the closest to the plug, and the penultimate lamp head is the farthest from the plug, so the connecting wires used are less than The traditional linear type has fewer light strings, which greatly saves wires and reduces product costs.

Detailed ways

Please refer to Fig. 2, the lamp string of Embodiment 1 includes a plug 1 that can be directly connected to the AC power supply, and a plurality of sub-lamp strings are connected in parallel through wires between the positive and negative poles of the plug 1 (only two sub-strings are shown in Fig. Light strings A and B), the first sub-light string A is connected in series by a plurality of lamp heads from A1 to An through wires, and the second sub-light string B is connected in series by a plurality of lamp heads from B1 to Bn through wires. The lamp heads of the light string and the second sub-light string are respectively arranged in a straight line and located on both sides of the plug 1, and the distance from the last lamp head of each sub-light string in series relationship to the plug 1 is the same, and the first sub-light string A , the second sub-light string B, the plug 1 and the wires connecting them together form a "Y" shape. The first lamp cap A1 of the first sub-light string A is respectively connected to the positive pole of plug 1 and the first lamp cap B1 of the second sub-light string B, and the last lamp cap An of the first sub-light string is respectively connected to the negative pole of plug 1, The last lamp head Bn of the second sub-light string B is connected. It can be seen from the figure that the distance between the lamp base A1 and the lamp base B1 is much shorter than that of the traditional linear light string, so the wire connecting the lamp base A1 and the lamp base B1 is also much shorter. Similarly, the wire connecting the lamp cap An and the lamp cap Bn, and the wire connecting the lamp cap An and the negative pole of the plug 1 are much shorter, which greatly reduces the production cost.

Please refer to FIG. 3 , the last lamp base Bn of the second sub-light string B in the second embodiment is directly connected to the negative pole of the plug 1 , and the other structures are the same as those in the first embodiment.
