Flexible rope light

Abstract

The invention discloses a flexible rope light, which comprises a flexible core wire, a light string arranged in the core wire, and a flexible transparent coating layer which coats the core wire and the light string. The flexible rope light is characterized in that: the light string comprises a plurality of chip LEDs which are connected through a conductive wire, and the light string is also connected in series with a current-limiting resistor; a first main power cord and a second main power cord serving as the main power cords are arranged on two sides of the core wire; a power plug and a power extension head which are electrically connected with the first main power cord and the second main power cord are arranged at the head end and the tail end of the flexible transparent coating layer; and the sum of the rated voltage of the plurality of chip LEDs and the resistor is equal to the input voltage of the rope light. By replacing the traditional flexible circuit boards by adopting a metal strip and the conductive wire, the flexible rope light can be applied to high-voltage drive, and the number of the chip LEDs is reasonably adjusted according to the input voltage of the rope light. Therefore, a switch power supply is saved, the manufacturing cost of the rope light is greatly reduced, and the length of the rope light is prolonged.

Description

technical field [0001] The invention relates to a decorative lamp, in particular to a flexible lamp strip. Background technique [0002] Nowadays, the application of light strips in various indoor and outdoor decorative lighting is more and more extensive, such as the outline decoration of indoor corners, outdoor building decoration and various advertising signs, the application of light strips can be seen everywhere. However, the existing light strips are generally connected by flexible circuit boards. The copper foil printed on the flexible circuit boards is very thin and cannot be driven by high voltage. Therefore, the existing light strips must be driven by step-down switching power supplies. Therefore, the existing light strips generally can only be made below 30V, and the length is limited. At the same time, the cost of the switching power supply accounts for nearly 40% of the cost of the entire light strip, and the production cost is very high. If a longer decorative...
