LED light converting plate and manufacturing method thereof

The invention provides an LED light converting plate and a manufacturing method thereof. The LED light converting plate comprises fluorescent powder and a high molecular polymer, wherein the high molecular polymer is polycarbonate, acrylic and polypropylene or polyester resin. The manufacturing method comprises the following steps of: weighing a certain amount of materials of the fluorescent powder and the high molecular polymer in proportion, and uniformly mixing; then manufacturing the mixture into a plate in a certain shape by methods of mould pressing, cold calendaring or injection moulding, and the like, and then the plate can be used. An LED lamp manufactured by using the light converting plate can obviously prolong the service life and solve the problem of glare of the traditional LED light source.
