Constant current resonant type LED driving power source
Disclosed is a constant current resonant type LED driving power source. The constant current resonant type LED driving power source is characterized by comprising, by weight, 70-85 parts of barium titanate, 5-10 parts of nanometer boron fibers, 1-2 parts of triethanolamine borate, 3-8 parts of calcium carbonate, 0.5-1 part of titanium trichloride, 5-8 parts of modified white carbon black, 0.5-1.5 parts of tungstate, 0.2-0.8 part of polypropylene, 0.5-1 part of silicon dioxide, 0.5-2 parts of silicon carbide, 0.8-1.2 parts of modified corn starch, 1-1.5 parts of calcined kaolin, 0.3-0.6 part of graphene microchips, 0.5-1 part of slaked lime and 0.5-1 part of purple grit mud. According to the constant current resonant type LED driving power source, the components are simple, the cost is low, and barium-titanate-based capacitor ceramics are adopted, so that the cost of a high-voltage ceramic capacitor is greatly lowered, no lead or cadmium exists in the medium components, no pollution is caused to the environment, and the constant current resonant type LED driving power source can be obtained through the conventional solid-phase method ceramic capacitor dielectric manufacturing technology.
