Example Embodiment
[0025] Example 1:
[0026] 1. Select the sapphire material as the substrate (1), and arrange the chips (2) with the peak wavelength of 360nm on the surface of the substrate (1) in an array; select silicone resin (6), multicolor phosphors (7), coupling The phosphor (8) is mixed to prepare the phosphor glue (4) through an injection molding process, and the phosphor glue (5) and the substrate (1) are placed in the mold, and the substrate (1) is relatively located in the center of the phosphor glue (5) Fixed position; choose TiO 2 Inorganic nano-particles (5) are mixed with transparent silica gel (3), and the mixed is uniformly injected into the middle of the substrate (1) and phosphor glue (5); a 360° full-circle luminous LED filament based on the violet chip can be obtained .
