Description

A LED copper wire light string

technical field

The utility model relates to an illuminating lamp string, in particular to an LED patch copper wire lamp string.

Background technique

LED light strings are widely used, such as building exterior decoration, room interior decoration, park, square decoration and so on. At present, the circuits of LED light strings are connected in parallel or in series, and the wires and LEDs are packaged in colloid, and the most common ones are copper wire light strings.

The existing LED copper wire light strings are electrically connected in parallel, and the input voltage is fixed. There are two common types: 12V and 24V. Therefore, series resistors are needed to divide the voltage, which causes additional power consumption by the resistors. In addition, because of the parallel circuit connection, a slightly longer length of the connected light string will produce an obvious voltage drop phenomenon, resulting in a relatively brighter LED at the front of the circuit, and a darker LED at the end of the circuit.

In addition, the existing LED light strings are generally connected to the power supply in parallel. After plugging in the power and turning on the switch, the light string will turn on and emit light. If you want to turn off the light string, you can only turn off the power supply at the head end of the light string. In other words, it is impossible to turn on and off the entire light string from the middle or tail end of a long light string. For example, the utility model patent with the patent No. ZL201020202536.9 is like this. Maintenance brings inconvenience to work, because usually the light strings are very long, and the installation distance between the head end and the tail end is also relatively long. To turn on the whole light string, it is necessary to run to the head end of the light string, which will inevitably cause inconvenience in work, time-consuming and labor-intensive, and poor work efficiency.

Therefore, there is room for improvement in the structure of the existing LED light string.
