Description

technical field [0001] The invention belongs to the technical field of LED ceramic filaments, and in particular relates to a nano-zirconia ceramic LED filament and a manufacturing method thereof. Background technique [0002] Traditional incandescent lamps (tungsten filament lamps) have been gradually banned from production due to their high energy consumption and short lifespan under the environment of tight global resources. The subsequent substitute products are electronic energy-saving lamps. However, due to the use of many heavy metal elements that pollute the environment, it goes against the general trend of environmental protection. With the rapid development of LED technology, LED lighting has gradually become the best choice for new green lighting. LED is far superior to traditional lighting products in terms of luminous principle, energy saving and environmental protection. [0003] As the core component of high-power LED lighting, the filament is currently made ...
