| description | The invention relates to a structure of a keyboard backlight module. A shading layer, a first adhesive layer, a light guide layer, second adhesive layers, a reflective layer and a circuit board of the backlight module are stacked in sequence. The light guide layer is provided with multiple light guide slots, the reflective layer is provided with multiple reflective slots, and the light guide slots correspondingly face the reflective slots. The multiple second adhesive layers are arranged between the multiple light guide slots of the light guide layer and the multiple reflective slots of the reflective layer. The multiple second adhesive layers are each provided with a light source guide slot towards the lateral side. The multiple light guide slots of the light guide layer, the multiple reflective slots of the reflective layer and the multiple second adhesive layers are assembled above luminous bodies of the circuit board in an aligned manner, and the light source guide slot of each second adhesive layer is arranged outside the light source protection plane of the corresponding luminous body. Therefore, the purpose of guiding the light sources of the luminous bodies to be projected in a concentrated manner in a predetermined direction is achieved. |
