Abstract

A light module is provided with a bulb shield. The light module includes a light generation unit for emitting light and an optic for shaping the light emitted by the light generation unit. The light generation unit includes a light-emitting surface. A bulb shield is arranged between the optic and the light generation unit for covering the light generation unit. The bulb shield includes a passage for the light emitted by the light-emitting surface. The light module includes a bearing structure for the bulb shield. The bulb shield is glued to the bearing structure by a first adhesive bond and the bulb shield is glued to the bearing structure by a second adhesive bond. A first adhesive used to produce the first adhesive bond and a second adhesive used to produce the second adhesive bond are different.
