DC24V non-pressure-drop lamp belt and fixing method thereof

Abstract

The invention discloses a DC24V non-pressure-drop lamp belt and a fixing method thereof. A lamp belt body of the non-pressure-drop lamp belt comprises a flexible circuit board and a plurality of lampbeads, a plurality of grooves are formed in the surface of the flexible circuit board in the length direction, and a conductive groove is arranged in each groove; and a conductive layer is arranged inthe flexible circuit board, the conductive grooves communicate with the conductive layer, two conductive columns are arranged at the bottom of each lamp bead, the conductive columns are inserted intothe conductive grooves, an electric coupler comprises a protective shell and a constant voltage constant current circuit, the protective shell is fixed on one side of the lamp belt body, the constantvoltage constant current circuit comprises a TH1A1075 constant current drive chip and a constant current source, the TH1A1075 constant current drive chip is connected with the lamp belt in series, and the constant current source is connected with each lamp bead in series. A fixing method of the DC24V non-pressure-drop lamp belt makes the lamp belt fix more firmly, and the brightness of the lamp beads at the head and tail ends of the lamp belt is the same.

Description

technical field [0001] The invention relates to the technical field of light strips, in particular to a DC24V voltage-drop-free light strip and a fixing method thereof. Background technique [0002] At present, the single-ended (DC24V) light strips on the market have obvious color difference between the first and last ends after lighting up. In order to reduce the color difference, both ends are usually powered. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a DC24V non-voltage-drop lamp strip and its fixing method, which solves the problem of color difference between the head and the tail of the existing DC24V lamp strip after being lit. [0005] (2) Technical solution [0006] In order to achieve the above object, the present invention provides the following technical solutions: a DC24V non-voltage drop light strip, including a light strip body and an electrical conne...
