Abstract
A light source module includes a circuit board, a light source electrically coupled to the circuit board including a first light emerging face, a light guide plate close to the light source and including an light incident face, a reflective piece located on one side of the light guide plate, a diffusion plate located on another side of the light guide plate, a frame used to fix the circuit board, the light guide plate, the reflective piece and the diffusion plate. The light incident face and the light emerging face cooperatively forming an angle. Light from the light source is guided by the light guide plate and reflected by the reflective piece and diffused by the diffusion plate.
Claims10
A light source module comprising;
- a circuit board;
- a light source electrically coupled to the circuit board and having a first light emerging face;
- a light guide plate positioned close to the light source and having a light incident face, the light incident face and the first light emerging face cooperatively forming an acute angle;
- a reflective piece located on one side of the light guide plate proximate to the circuit board;
- a diffusion plate located on another side of the light guide plate away from the circuit board;
- and
- a frame fixedly holding the circuit board, the light guide plate, the reflective piece, and the diffusion plate, respectively;
- wherein, light emitted from the light source is guided by the light guide plate, reflected by the reflective piece and diffused by the diffusion plate to form a uniform planer light source.
