Abstract

A vehicular light includes a body having a base. A cover is mounted to a surface of the base and made of transparent material. A circuit board is mounted in the base. A light emitting element is mounted to the circuit board. An intermediate member is mounted between the cover and the circuit board. The intermediate member includes a light transmittable section covering the light emitting element. A frame is mounted between the light transmittable section and the light emitting element and has a substantially bowl-shaped inner side. The frame and the intermediate member are separable from each other and detachable from the cover and the circuit board. The frame includes a frame wall. A through-hole is formed in a bottom of the frame. The light emitting element extends through the through-hole and received in the frame and faces the light transmittable section.

Claims

1. A vehicular lamp comprising:

a body including a base, with a cover mounted to a surface of the base and made of transparent material, with a circuit board mounted in the base, with a light emitting element mounted to the circuit board, with an intermediate member mounted between the cover and the circuit board, with the intermediate member including a light transmittable section covering the light emitting element, with a frame mounted between the light transmittable section and the light emitting element and having a substantially bowl-shaped inner side, with the frame and the intermediate member being separable from each other and detachable from the cover and the circuit board, with the frame including a frame wall, with a through-hole formed in a bottom of the frame, with the light emitting element extending through the through-hole and received in the frame and facing the light transmittable section;

with the lighting element being a light-emitting diode, with a recess formed in a top face of the light transmitting section, with a protrusion formed on a bottom side of the light transmitting section and aligned with the recess and having a shape corresponding to the recess.

2. The vehicular lamp as claimed in claim 1, with the frame wall of the frame further including two lateral supporting walls extending upward from a top portion thereof, with the two lateral supporting walls clamping two sides of the intermediate member.

3. The vehicular lamp as claimed in claim 1, with the frame wall of the frame having an inner side, with the inner side of the frame wall of the frame being a reflective surface.
