Abstract

The invention relates to a rare earth activated aluminate system fluorescent material for an electrodeless lamp. The rare earth activated aluminate system fluorescent material for the electrodeless lamp is a mixture of a red material, a blue material and a green material, wherein the ratio of the red material to the blue material to the green material is 46: 25: 35, the red material, the blue material and the green material are fully mixed and then are mixed with appropriate amount of binder Na2SiO3, thus the product is obtained. The red material comprises yttrium oxide, europium oxide and boron oxide; the blue material comprises aluminium oxide, magnesium oxide, boric acid, barium carbonate, calcium carbonate, europium oxide, cerium oxide and dysprosium oxide; and the green material comprises aluminium oxide, magnesium oxide, boric acid, europium oxide, cerium oxide and terbium oxide. The production process of the preparation method of the rare earth activated aluminate system fluorescent material comprises the steps of sorting, mixing in proportion, placing the materials into a crucible reacting furnace, igniting and heating, insulating heat, cooling, smashing and sieving, carrying out dry grinding and wet grinding, cleaning, dehydrating and stoving, sieving and checking as well as bagging.

Description

technical field [0001] The invention relates to an aluminate system fluorescent material activated by related rare earth materials, which is the main inner coating material of an electrodeless lamp. Background technique [0002] The luminescence of the traditional light bulb is that the electrode wire in the bulb converts electrical energy into light energy to emit light, which has low luminous efficiency and high energy consumption. The existing electrodeless lamp also has the problems of low luminous efficiency, difficult adjustment of color and luster and high production cost. Contents of the invention [0003] The purpose of the present invention is to develop a rare earth activated aluminate system fluorescent material for electrodeless lamps and a manufacturing method. [0004] The invention aims to solve the problems of low luminous efficiency, difficult color adjustment and high production cost of the existing electrodeless lamp. [0005] The rare earth activat...
