Description

Technical Field

[0001] The utility model relates to the technical field of BT board colorful lamp beads, in particular to a BT board colorful lamp bead packaging structure. Background Art

[0002] Colorful lamp beads usually refer to LED lamp beads with colorful light effects, which can produce rich color changes and special effects. Such lamp beads are often used in decoration and lighting fields, and have good visual effects and atmosphere creation functions. Colorful lamp beads usually adopt LED light-emitting technology to achieve different light effects by controlling the brightness and color of LED lamp beads, such as breathing light effects, gradient color effects, flashing effects, etc. These lamp beads can be used alone or remotely controlled through a controller or smart home system to achieve personalized light adjustment and timed switching.

[0003] When the existing fantasy lamp beads are packaged on a BT circuit board, their signal lines and power lines are often welded to the welding positions of the BT circuit board. Since the existing BT circuit board does not have a special soldering pad, it is easy to produce tin connection during welding, which in turn causes a short circuit and affects the use. In addition, the wires connected to the existing BT circuit board, the optoelectronic LED chip and the internal control fantasy IC are generally positioned by a molding process and an epoxy glue layer in combination with the epoxy glue layer. However, the existing BT circuit board is generally made of BT resin. Since the molding process generates high temperature, the resin material is difficult to withstand, and the epoxy glue layer cannot accurately position the wires, resulting in insufficient product yield and practicality that needs to be improved.
