Abstract: A vehicle lamp for installing on a vehicle includes a projector lens, a reflector, a first light emitting element, a shield, and an optical grating unit. The projector lens has a light entry surface and a light exit surface. The first light emitting element is adjacent to a first focal point of the reflector, and is for emitting light towards the reflector. The shield is for blocking a portion of the light that is emitted from the first light emitting element to form a cut-off line in a light distribution pattern. The optical grating unit is for reflecting at least a portion of the light that has passed a second focal point of the reflector and that has not passed through the light exit surface of the projector lens.
Abstract: A vehicle lamp adapted to be installed on a vehicle includes a projector lens, a reflector, a light emitting element, and a grating plate. The projector lens has a light entry surface and alight exit surface. The light emitting element is disposed for emitting light towards the reflector, such that the light is reflected by the reflector to pass through the projector lens to form a light distribution pattern. The grating plate is for reflecting at least a portion of the light that has traveled ahead of a second focal point of the reflector and that has not passed through the light exit surface of the projector lens. An extension of the grating plate and the optical axis defines an angle between 0 degree and 45 degrees.
