Abstract
The invention discloses an LED lamp circuit board for integrating a light source and a power supply with the advantages of reliable connection, fast and simple production, high production efficiency and high product qualification ratio and a manufacture method thereof. The LED lamp circuit board comprises at least two module unit boards (1), wherein every two module unit boards (1) are fixedly connection, a metal layer (13) used for fixing LED chips (2) and forming electric connection between every two LED chips (2) is arranged on the front surface of each module unit board (1), a power line (14) which is welded with a circuit element to form a circuit is arranged on the back surface of each module unit board (1), and every two power lines (14) of two connected module unit boards (1) are electrically connected through a jumper wire phase. The manufacture method comprises the following steps of: manufacturing prefabricated circuit boards into a connected circuit board, patching the whole connected circuit board, carrying out wire bond, coating fluorescent powder and silica gel, welding the circuit element after curing, cutting each module unit board (1) into independent parts, connecting the independent parts through connecting parts and electrically connecting the power lines (14) through jumper wires. The invention can be applied to a light emitting diode illumination field.
