Ultrathin flexible lamp band

Abstract

The invention discloses an ultrathin flexible lamp band, comprising a flexible core wire and a plurality of lamp clusters installed in the core wire. Each lamp cluster comprises a plurality of paster LEDs connected through electric leads, and the lamp clusters are also connected with a current-limiting resistor in series. The core wire is also internally provided with a main power line, and the lamp clusters are connected to the main power line in parallel. A flexible transparent covering layer for sealing the lamp clusters covers the emergent face of the core wire, and one side of the core wire, which is back to light, is provided with an insulating protection layer. The head ends and the tail ends of the flexible transparent covering layer and the protection layer are also provided with a power supply plug and a power supply extension joint which are connected with the main power line. In the invention, the power line is utilized to replace the traditional flexible circuit board, the paster LEDs are used as light sources, and the very thin flexible transparent covering layer only covers the emergent face of the core wire, thereby the flexible lamp band is very thin, has good flexibility, is convenient to be made into various bent shape, and furthermore, the service life of the lamp band is prolonged.

Description

technical field [0001] The invention relates to a decorative lamp, in particular to an ultra-thin flexible lamp strip. Background technique [0002] Nowadays, the application of light strips in various decorative lighting indoors and outdoors is becoming more and more widely, such as the outline decoration of indoor corners, outdoor building decoration and various advertising signs, the application of decorative light strips can be seen everywhere. However, the existing decorative light strips generally have a relatively thick lamp body, large bending stress, inconvenient shape, difficult installation and fixing, and are not conducive to subsequent packaging and transportation. In order to reduce the thickness of the light strip, people later replaced the traditional power cord with a flexible circuit board, which reduced the thickness of the light strip. However, the flexible circuit board is very thin, and it is easy to be pulled by an external force and break. In additio...
