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 that can be directly connected to the AC power supply and a tail plug 2, and a plurality of sub-light strings are connected in parallel through wires between the positive and negative poles of the plug 1 (in Only two sub-strings A and B are shown in FIG. 1 . Similarly, the sub-strings A and B are also connected in parallel between the two poles of the tail plug 2 . In the first sub-light string A, a plurality of lamp caps from A1 to An are connected in series through wires, and in the second sub-light string B, a plurality of lamp caps from B1 to Bn are connected in series through wires. Plug 1, the first sub-light string A, The second sub-light string B and the tail plug 2 are arranged in a straight line. Among them, the first lamp cap A1 of the first sub-light string A is the closest to the plug 1, followed by A2 to An, and B1 to Bn; the last lamp cap Bn of the second sub-light string B is the closest to the tail plug 2, followed by sequence It is B(n-1) to B1, An to A1. 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 A is respectively connected to the negative pole of plug 1. , Connect to the last lamp head Bn of the second sub-light string B; Bn connection. 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 wires connecting the lamp cap An and the lamp cap Bn, the wires connecting the lamp cap An and the negative pole of the plug 1, and the wires connecting the positive pole of the tail plug 2 and the lamp cap B1 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 object, 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 tail plug, and a plurality of lamps are connected in parallel through wires between the positive and negative poles of the plug and the tail plug. Light strings, each sub-light string is connected in series by a plurality of lamp holders through wires, and the characteristic is that in each sub-light string, the last lamp holder in the series relationship is the closest to the plug and the tail plug, and the penultimate lamp holder The furthest from the plug and jack.

The sub-light strings include a first sub-light string and a second sub-light string, and 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 and the tail 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. Connect to the last lamp head of the tail plug, connect the positive pole of the tail plug to the first lamp head of the second sub-light string, and connect the negative pole of the tail plug to the last lamp head of the second sub-light string.

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

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, the tail plug and the wires connecting them are combined to form a "Y" shape.

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

Compared with the prior art, among the sub-lamp 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 tail plug, while the penultimate lamp head is the farthest from the plug and the tail plug. Therefore, the connecting wires used are less than those of the traditional linear light string, which greatly saves the wires and reduces the product cost.

Detailed ways

Please refer to Fig. 2, the light string of the first embodiment includes a plug 1 and a tail plug 2 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 and the tail plug 2 (in Only two sub-light strings A and B are shown in Figure 2). The first sub-light string A is connected in series by a plurality of lamp caps from A1 to An through wires, and the second sub-light string B is connected by a plurality of lamp caps from B1 to Bn. The wires are connected in series, and 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 1 and the tail plug 2, and the last lamp cap of each sub-light string in the series relationship is to The distance from the plug 1 is the same, and the distance from the tail plug 2 is also the same. The combination of 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, the positive pole of the tail plug 2 is connected to the first lamp head B1 of the second sub-light string B, the negative pole of the tail plug 2 is connected to the last lamp head Bn of the second sub-light string B connect. 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 wires connecting the lamp cap An to the lamp cap Bn, the wires connecting the lamp cap An to the negative pole of the plug 1, and the wires connecting the lamp cap B1 to the positive pole of the tail plug 2 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.

Although the present invention is disclosed above with a preferred embodiment, it is not intended to limit the implementation scope of the present invention. Any person skilled in the art may make some improvements without departing from the scope of the present utility model, that is, all equivalent improvements made according to the present utility model shall be covered by the scope of the present utility model.
