Abstract
A lighting module includes a main circuit board, a plurality of lighting units, and a driving unit. The main circuit board forms a plurality of through holes. Each lighting unit includes a transparent substrate, a circuit layer, a plurality of light emitting diode (LED) dies, and a transparent resin layer. The transparent substrates are arranged on the main circuit board, and then a predetermined angle spans between a first surface of each transparent substrate and the main circuit board. The circuit layer and the LED dies are placed on the first surface, and the LED dies are electrically connected to the circuit layer. The transparent resin layer covers the LED dies. The driving unit includes a driving circuit board including a plurality of protrusions. The protrusions are respectively inserted into the through holes such that the driving circuit board is substantially perpendicular to the main board.
