The invention discloses an LED (light-emitting diode) ceramic packaging material, which is prepared by calcining the following components: 6-8 parts of nano-magnesia, 10-12 parts of chromium sesquioxide, 10-15 parts of barium hydroxide, 5-6 parts of sodium hydroxide, 5-8 parts of potassium hydroxide, 3-5 parts of aluminum hydroxide, 5-8 parts of copper chloride, 80-100 parts of kaolin, 3-5 parts of zinc oxide, and 5-8 parts of calcium carbonate. The LED ceramic packaging material is low in manufacturing cost and uniform in material distribution, therefore, the packaging material is extremely applicable to the large-batch technologic production of finished products; and through the reasonable allocation of the components, the peak of a reflectance curve of a finished product is adjusted to be close to a wavelength of 420 nm, and a strong absorption peak which coincides with the visual characteristics of human eyes exists from purple light to an ultraviolet area, thereby improving the light output efficiency of the LED material.
