Flexible LED light bar manufacturing method

271-201811162239303860

Background technique:
Nowadays, LED light strips are widely used in daily production, such as wall washers, etc. Wall washers are also called line-type LED floodlights and LED line lights, mainly for architectural decoration lighting, and for sketching large buildings. Outline; its main application areas are: single building, historical building group exterior wall lighting, building exterior lighting, indoor partial lighting; green landscape lighting, billboard lighting, medical culture and other special facilities lighting, bars, dance halls, etc. Entertainment atmosphere lighting and so on.
The outline of such a building cannot be straight everywhere. When encountering a non-linear building, the traditional LED light bar is rigid, and the LED light bar needs to be cut to make a length suitable for the building to continue the installation. The process is troublesome, and the LED light bar at the corner position will have obvious faults, which will affect the lighting decoration effect.
The existing flexible LED light bar adopts a flexible circuit board, and an LED light source is disposed on the flexible circuit board, and then wrapped with a flexible wrapping layer. However, the problem encountered in this structure is that the flexible circuit board is deformed, so that During the process of bending the LED light bar, it is easy to loosen the LED light source disposed on the circuit board, and at the same time, it is impossible to cover the LED light source with the lens assembly, and the lens assembly cannot be firmly disposed on the LED light bar of the structure. Therefore, the LED light bar has a poor lighting effect.
Technical realization elements:
In order to solve the above technical problems, Xin Jiuyuan provides a flexible LED light bar.
The technical solution adopted by the utility model is:
A flexible LED light bar, comprisinga plurality of circuit boards and an LED light source disposed on the circuit board, wherein the LED light source is electrically connected to the circuit board;
a flexible wrap layer wrapped around the circuit board and the LED light source;
The flexible electrical components are electrically connected to adjacent circuit boards respectively to enable flexible and electrical connection between adjacent circuit boards.
The LED light bar further includes a lens assembly that is disposed on the LED light source and connected to the circuit board.
The lens assembly includes a lens and a lens holder for fixing the lens. The lens and the lens holder are integrally formed. The lens holder is connected to the circuit board, and the lens cover is disposed on the LED light source.
The lens assembly includes a lens and a lens holder for fixing the lens, the lens holder being coupled to the circuit board, the lens cover being disposed on the LED light source, and the lens being detachably coupled to the lens holder.
The flexible wrap layer includes an outer flexible wrap layer, and the circuit board and the LED light source are wrapped within the outer flexible wrap layer.
The flexible wrapping layer comprises an outer flexible wrapping layer and an inner flexible wrapping layer;
The LED light bar further includes a lens assembly, the lens assembly is disposed on the LED light source and connected to the circuit board;
The inner flexible wrap layer is respectively coupled to the lens assembly and the circuit board to fix the position of the lens assembly and the circuit board, and the circuit board, the LED light source, the lens assembly, and the inner flexible wrap layer are wrapped in the outer flexible wrap layer.
A fixing hole for allowing the fixed lens assembly is provided on the inner flexible wrapping layer.
The LED light bar further includes an electrical connection terminal for electrically connecting to an external driving power source or another LED light bar, and the electrical connection terminal is electrically connected to the circuit board.
A through hole for piercing the electrical connection terminal is disposed on the flexible wrapping layer.
The beneficial effects of the utility model:
The flexible LED light bar of the utility model is arranged on the circuit board, and the adjacent circuit board is flexible and electrically connected by the flexible electrical connecting component, and then wrapped by the flexible wrapping layer, so that the entire LED light bar can be flexibly bent, and the circuit board It will not be deformed because the LED strip is bent, so that the LED light source placed on the circuit board will not be loose. At the same time, in the shape-changing building, the staff can bend the flexible LED strip and install it in the building. The installation process is simple and the appearance is beautiful.
The lens assembly can be firmly fixed on the circuit board, and the lens assembly is disposed on the LED light source, so that the LED light bar has better illumination effect.
