Description

Technical Field

[0001] The utility model relates to the technical field of lighting, and in particular to an LED filament assembly with a flexible carrier and a tooling fixture thereof. Background Art

[0002] Existing light bulbs with patterned shapes generally use a metal bracket as a fixing member, an LED light strip is wound around the metal bracket, and the light strip is fixed by a small hook on the metal bracket, thereby forming various patterns, such as animals, celebrity signatures, cartoon graphics, various paintings, etc., making the shape more aesthetically pleasing. However, this method is too limited. The metal bracket is expensive and difficult to manufacture. In addition, the mouth size of the bulb shell is limited. When making complex patterns or patterns larger than the mouth size of the bulb shell, a folding structure needs to be provided on the bracket, resulting in a complex bracket structure and further increasing the cost of the bracket. At the same time, the bulb shell is made of glass, and the metal bracket and the bulb shell are easily collided, causing the bulb shell to be damaged, and the safety is not high. In addition, the scope of use of metal brackets is narrow and they cannot be used on many products. For example, when LED filament shapes are required on clothing or art paintings, the metal bracket is large and difficult to apply. In addition, the mold opening and production cost are high, making it difficult to achieve small-scale production or personalized customization. Utility Model Content
