The invention belongs to the field of
semiconductor illumination and particularly relates to a method for improving LED (
Light Emitting Diode) encapsulation. The method for improving the LED encapsulation comprises the following steps that LED chips are fixedly arranged on a substrate containing a printed circuit layer; cathodes of the chips are connected with the
cathode of the printed circuit layer of the substrate; anodes of the chips are connected with the
anode of the printed circuit layer of the substrate; the
anode of the printed circuit layer of the substrate is connected with the
cathode of the printed circuit layer; the
anode and the
cathode of the printed circuit layer are connected in a short-circuit way; a mixture of well-proportioned fluorescent
powder and
silica gel is stirred and then coated onto the chips; and a
light source semi-finished product is put in a roaster for
roasting. With the adoption of the method for improving LED
light source encapsulation provided by the invention, through the short-circuit connection between the anode and the cathode of the substrate, the anodes and the cathodes of the chips are located on the same
potential difference, so that an external
electric field resulting from LED intrinsic absorption is eliminated; and therefore, the purpose of evenly distributing the fluorescent
powder is realized, and the light color yield of a
light source product is further improved.
