Method for manufacturing a vehicular lamp and a vehicular lamp

1. A method for manufacturing a vehicular lamp in which a front lens thereof is provided with a wire for heating the front lens, said method comprising the steps of:

installing a wire in a resin plate of a flat shape by heat;

forming the resin plate into a predetermined shape;

trimming the resin plate of the predetermined shape into a desired shape to form the front lens; and

fixing the front lens to a lamp body by optical welding.

2. The method for manufacturing a vehicular lamp according to claim 1 , wherein

the resin plate is subjected to ultrasonic vibration so as to be heated and melted, thus allowing at least a portion of the wire is embedded in the resin plate.

3. The method for manufacturing a vehicular lamp according to claim 1 , wherein

the wire installed comprises a plurality of vertical wire portions that extend in a vertical direction of the resin plate and a plurality of connecting portions that connect respective ends of adjacent vertical wire portions, and

a length of the vertical wire portions is set to be longer than a length of the connecting portions.

4. The method for manufacturing a vehicular lamp according to claim 1 , wherein

the resin plate has a thickness of 2 mm to 4 mm.

5. The method for manufacturing a vehicular lamp according to claim 1 , further comprising the step of forming a coating layer that covers the wire installed in the resin plate.

6. The vehicular lamp according to claim 1 , further comprising a coating layer provided on said resin plate so as to cover said wire installed in said resin plate.

7. A vehicular lamp in which a front lens thereof is provided with a wire for heating the front lens, wherein

the front lens is comprised of a resin plate, the resin plate being installed with a wire by heat, formed into a predetermined curved shape and then trimmed into a desired front lens outer contour shape; and

the front lens is fixed to a lamp body by optical welding.
