Abstract

The invention relates to a centrifugal method and unit of an LED device. The centrifugal unit of the LED device comprises a main rotating disc, at least one subsidiary rotating disc and a driving motor. A first central shaft is arranged in the center of the main rotating disc; a second central shaft is arranged in the center of each subsidiary rotating disc; the second central shafts are fixed tothe periphery of the main rotating disc; a centrifugal cavity is defined by each subsidiary rotating disc; and a plurality of material boxes are arranged on the inner wall of each centrifugal cavity.The driving motor comprises an output shaft and is connected with the main rotating disc and the subsidiary rotating discs through the output shaft.

Description

technical field [0001] The invention relates to the technical field of LED packaging, in particular to a centrifugal method and device for an LED device. Background technique [0002] In the process of LED production and packaging, in order to avoid different degrees of precipitation of phosphor powder in the fluorescent colloid due to different glue filling times, the color temperature offset of the product is too large, and for the performance of LED devices such as luminous efficiency and light output Optimizing, and adopting the method of thoroughly precipitating the phosphor powder in the fluorescent colloid for production and packaging. [0003] The methods that can achieve the purpose include electrophoresis, spraying, static precipitation and centrifugal precipitation, etc., but the electrophoresis method will generate a lot of chemical waste, the spraying method is difficult to control the color temperature consistency and the equipment is expensive, and the static ...
