Abstract
The present invention provides a light emitting module with a light guide plate for an automotive headlight, which light guide plate includes a front surface for exiting light; a rear surface positioned opposite to the front surface and used as a first light incidence surface for introducing a first light beam; and a side surface positioned at a side of the light guide plate and used as a second light incidence surface for introducing a second light beam. The light guide plate has a number of concave structures at the rear surface thereof for refracting the first light beam downwards towards the ground and for reflecting the second light beam forwards towards the front surface of the light guide plate. The overall output light beam pattern according to the present invention would appear to be uniform.
