Problems solved by technology
Compared with the lamp bead, in order to make it emit light evenly, the pagoda-shaped insertion method is usually used, but for the LED patch, it can only be installed on a flat surface. This installation method makes the light projected on the lampshade uneven, which solves the problem. The problem of non-uniform light emitting diode patches becomes the focus of the present invention

Embodiment 1
[0014] Such as figure 1 As shown, a three-dimensional stretched spiral circuit board on an LED lamp in this embodiment includes a three-dimensional spiral PCB circuit board 1 after stretching a plane spiral PCB circuit board, and the PCB circuit board 1 includes The chassis 2 and the patch mounting part 3; the PCB circuit board 1 can be an epoxy circuit board or an aluminum-based circuit board. A patch light-emitting diode 4 is mounted on the patch mounting portion 3 . The chassis 2 is engaged and fixed with the inner wall of the lamp housing. In order to strengthen the fastness of the main body 1 , clips 5 can be installed on the patch installation part 3 , and the fastness can be provided by installing pillars 6 between the clips 5 . The manufacturing method of the three-dimensional stretched spiral circuit board on the LED lamp of this embodiment is as follows: first, engrave a spiral continuous groove on the circuit board, and weld and install the patch between the spira...

The invention discloses a method for manufacturing a three-dimensional tensile and helical circuit board (1) for a LED lamp comprises the steps of: forming a helical continuous carved wire slot on a circuit board; providing patch light-emitting diode tubes (4) to be welded in between the helical continuous carved wire slot; and directly tensioning a center of the circuit board and lifting the tensioned circuit board along the helical continuous carved wire slot to form as the three-dimensional tensile and helical circuit board (1). The invention enable the light to be uniformly projected on a lamp shade from the LED patches, realizing the LED lamp with a long life span, low manufacturing cost and excellent reliability.
Description
technical field [0001] The invention relates to a three-dimensional stretched spiral circuit board on an LED lamp and a manufacturing method thereof. Background technique [0002] Current LED lamps generally use a flat circuit board, on which lamp beads are inserted or light-emitting diode patches are installed. Compared with the lamp bead, in order to make it emit light evenly, the pagoda-shaped insertion method is usually used, but for the LED patch, it can only be installed on a flat surface. This installation method makes the light projected on the lampshade uneven, which solves the problem. The problem of non-uniform luminescence of light-emitting diode patches becomes the key point of the present invention. Contents of the invention [0003] The purpose of the present invention is to provide a three-dimensional stretched spiral circuit board on an LED lamp and a manufacturing method thereof. The present invention has the characteristics of uniform light emission of ...
