Abstract

The invention discloses a built-in IC programmable control full-color integrated LED which comprises a packaging carrier, a light-emitting chip and a driver IC. The packaging carrier is of a bowl-cupshape; six metal bonding pads are arranged in the packaging carrier; each bonding pad extends to form a corresponding pin; the pins are positioned at the bottom of the packaging carrier; the light-emitting chip and the driver IC are arranged on the bonding pads; the driver IC is provided with eight welding spots; and the driver IC, the light-emitting chip and each pin are connected by conductive wires so as to form one complete LED full-color integrated circuit. A carrier required by one single LED is omitted; a production process is simplified; the number of devices is reduced; production cost is reduced; and production efficiency and yield of a product are improved.

Description

technical field [0001] The invention belongs to the technical field of LED light-emitting diodes, in particular to a full-color integrated LED with a built-in IC programmable control. Background technique [0002] Most of the existing LED lanterns are equipped with an LED and a carrier, and the carriers are all planar structures. Light-emitting chips are arranged on the planar carrier structure, which makes the structure more complicated and the manufacturing cost is relatively high. For example: in China In the patent application number 201220492660.2, a kind of LED colored lamp is disclosed, which is described as "a kind of LED colored lamp, which is characterized in that it includes a housing, a cable, a lampshade, an LED strip circuit board and a control circuit board, The lampshade is arranged on the outside of the light strip circuit board, the LED light strip circuit board and the control circuit board are installed inside the housing, and are connected to each other ...
