Abstract
Provided is an automotive lamp assembly that can dynamically control the amount and direction of side radiation of light, as a vehicle travels along a curved road. The lamp assembly includes a projection lamp module including a light source, a reflecting mirror reflecting light emitted from the light source forward, and a lens refracting and condensing the forward reflected light; a rotative actuator rotating the module about a predetermined driving axis; and an additional reflecting mirror rotating with the module and reflecting light intercepted by a shield to make the light travel at an angle in a direction proportionate to the rotation.
Claims8
A lamp assembly comprising:
- a projection lamp module including a light source, a reflecting mirror reflecting light emitted from the light source forward, and a lens refracting and condensing the forward reflected light;
- a rotative actuator rotating the module about a predetermined driving axis;
- a shield unit intercepting a part of the light emitted from the light source, the shield unit being provided with an inverse reflecting mirror disposed on an outer surface of the shield unit facing the light source and reflecting the light intercepted by the shield unit downward to form a low beam pattern;
- and
- an additional reflecting mirror rotating with the module and reflecting the light reflected by the inverse reflecting mirror to make the light travel outside through an opening provided at a position below the shield unit at an angle in a direction proportionate to the rotation of the module so as to form an additional beam pattern at a lateral side of the low beam pattern,
- wherein a rotational angle of the additional reflecting mirror is larger than a rotational angle of the module.
