Abstract
A vehicular lamp includes a housing having a chamber. The housing includes a heat dissipating portion made of metal. The housing further includes a platform integrally formed with the heat dissipating portion. The platform includes a coupling portion. A reflective cover is mounted in the chamber and includes a recessed portion in. The recessed portion has a rear end with an opening. The platform extends through the opening, and the coupling portion is received in the recessed portion. The recessed portion includes a reflective face. A light-emitting diode unit includes a plurality of light-emitting diodes fixed to the coupling portion and a circuit board fixed to the coupling portion. The light-emitting diodes emit light rays towards the reflective face of the reflective cover. A shield is mounted in front of the housing and is transmittable to the light rays.
