Description

Technical Field

[0001] The utility model belongs to the technical field of LED filaments, and in particular relates to a surface spraying device for an LED filament. Background Art

[0002] LED filaments are also called LED lamp posts. In the past, in order for LED light sources to achieve a certain illuminance and illumination area, optical devices such as lenses needed to be installed, which affected the lighting effect and reduced the energy-saving effect of LEDs. LED filaments can emit light at all angles and at large angles without the need for lenses, thus achieving a three-dimensional light source and bringing an unprecedented lighting experience. At present, during processing, the surface of LED filaments will be sprayed with paint to produce a protective or fluorescent coating. The coating of the filament is generally formed using a spraying device.

[0003] The existing spraying device is mainly composed of a spray pump for feeding materials and a nozzle for spraying materials. Since the flexible LED filament is not convenient to pass through the nozzle area with limited spraying range after bending, it is easy to miss the spraying. In addition, the straightening operation before the subsequent fixed-length slitting and truncation of the filament is easy to scratch the coating. In addition, the sides of the filament need to be sprayed, which makes it inconvenient for the traditional single-direction arranged nozzle to carry out comprehensive spraying. At the same time, placing the filament directly on the operating table during the spraying process will also affect the spraying effect on the back. Utility Model Content
