Description
技术领域technical field
本发明涉及LED技术，特别涉及一种LED灯丝灯。The invention relates to LED technology, in particular to an LED filament lamp.
背景技术Background technique
现有的LED灯丝灯，其灯条通过金属导线点焊以实现导电和固定，金属导线来料时固定于玻璃芯柱上，在运输包装时容易产生歪斜，因此，当生产灯丝灯时，需先对玻璃芯柱上的金属导线进行理线和剪线。然而，灯丝灯生产的理线和剪线工序较繁琐，使灯丝灯生产的效率降低且成本提高。例如，现有工厂的灯丝灯生产的理线工序一般有5道左右，其剪线工序有2道左右，生产工序多，明显降灯丝灯的生产效率且增加生产成本。此外，由于需要进行上述理线和剪线工序，因此，现有的LED灯丝灯无法上自动化生产线，即无法支持自动化生产。In the existing LED filament lamps, the light bar is spot-welded with metal wires to achieve conduction and fixation. When the metal wires are supplied, they are fixed on the glass stem, which is prone to skew during transportation and packaging. Therefore, when producing filament lamps, it is necessary to Arrange and trim the metal wires on the glass stem first. However, the wire arranging and trimming processes of filament lamp production are cumbersome, which reduces the efficiency and increases the cost of filament lamp production. For example, there are generally about 5 wire arranging processes in the production of filament lamps in existing factories, and about 2 wire cutting processes. There are many production processes, which obviously reduce the production efficiency of filament lamps and increase production costs. In addition, due to the need for the above-mentioned wire management and wire trimming processes, the existing LED filament lamps cannot be used in an automated production line, that is, they cannot support automated production.
