摘要： A lighting module includes a circuit board, a light emitting diode, a light guide plate, and a waterproof adhesive. The circuit board has an insulating layer, a metal layer, and a circuit layer. The insulating layer is interposed between the metal layer and the circuit layer. The metal layer has an opening exposing a portion of the insulating layer. The light emitting diode has a light emitting surface and a non-light emitting surface facing the metal layer. The light guide plate is parallel or substantially parallel to the circuit board and is adjacent to the light emitting surface of the light emitting diode. An optical axis of the light emitting diode coincides with or substantially coincides with a symmetry axis of the light guide plate. The portion of the insulating layer is adhered to the light guide plate through the waterproof adhesive.
