Abstract

The invention discloses a flexible lamp filament for a light emitting device and a fabrication method of the flexible lamp filament. The flexible lamp filament comprises a flexible substrate, a conductive layer, a first group of light emitting units and wrapping layers, wherein the flexible substrate has a predetermined length, a predetermined width and a predetermined thickness and is provided with an upper surface and a lower surface, the conductive layer is arranged on the upper surface of the substrate, the first group of light emitting units are arranged on the upper surface of the substrate and pass through the conductive layer to form electric connection, and the wrapping layers are arranged on the upper surface of the substrate and completely cover the first group of light emitting units. The lamp filament disclosed by the invention can be randomly bent, has a wider light emitting angle, and is beneficial for design and fabrication of the light emitting device which is attractive and free.

Description

technical field [0001] The invention relates to devices in the field of photoelectric lighting, in particular to a bendable filament for a light emitting device and a manufacturing method thereof. Background technique [0002] Light-emitting diodes are a widely used light source in semiconductor components, and have the advantages of environmental protection, energy saving, and long life. Therefore, it has become a mainstream trend to use light-emitting diodes in traditional lighting fixtures. However, since the light-emitting angle of LEDs is smaller than that of traditional light sources, and LED components are made of hard materials, traditional LED component packaging requires optical components such as lenses or diffusers to increase the lighting range, and the appearance variability is limited. , but cannot meet the needs of the society in the existing new era for more beautiful and more free lamps and lanterns, so as to be suitable for the needs of changing indoor des...
