Abstract

The invention discloses a method for manufacturing a white light LED product with uniform light spots and the white LED product. The method comprises steps that S1, an LED wafer is set on a LAMP holder through a die bonder through using a die bond primer; S2, the LED wafer is connected with positive and negative electrodes of the LAMP holder through a gold wire bonding machine by employing the leading wire bonding technology; S3, the fluorescent glue solution is prepared, the LED wafer is wrapped in the fluorescent glue through a dispensing machine; S4, the fluorescent glue solution on the LEDwafer obtained in the S3 is baked; S5, an outer sealing glue solution is prepared; and S6, the outer sealing glue solution obtained in the S5 is filled through a glue filling machine to the LED waferobtained in the S4 and is then baked. The white LED product is made based on the method. The method is advantaged in that light spot consistency of the obtained white light LED product is good, products are in a bin set, and good sensory performance is realized.
