发明名称 Vehicular lamp
摘要 In a vehicular lamp, a first zone includes a first incident portion disposed on a radiation axis. A first light guide portion guides light incident from the first incident portion forward. A first radiation portion formed from a first concave surface and a second concave surface deflects the light from the first light guide portion toward a lamp optical axis side and radiates such light forward in a diffused manner. A second zone includes a cylindrical second incident portion disposed on an outer side of the first incident portion. A second light guide portion that is longer in the direction of the radiation axis than the first light guide portion guides light incident from the second incident portion forward. A cylindrical second radiation portion radiates the light from the second light guide portion forward.
