Abstract
A vehicle lamp having a discharge bulb which prevents radiation of electromagnetic waves toward the forward positions of the lamp. Radiation into the other directions is prevented by shielding members disposed around the lamp. A shade disposed in front of a discharge bulb attached to a reflector is made of metal and a stem of the shade is secured to the reflector in a state where the stem is electrically connected to a socket fixture. The shade is placed at ground potential through the fixture. Thus, the front portion of the discharge bulb is shielded and prevents radiation of the electromagnetic waves to positions in front of the lamp.
Claims14
A vehicular lamp comprising:
- a lamp body;
- a discharge bulb disposed in said lamp body serving as a light source;
- and
- a shade disposed in said lamp body in front of said discharge bulb so as to limit an illumination range for a light beam emitting from said discharge bulb, said shade being made of a conductive material and maintained at ground potential.
A vehicular lamp comprising:
- a reflector;
- a socket fixture secured to said reflector, said socket fixture being maintained at a ground potential;
- a discharge bulb coupled to said socket fixture;
- and
- a shade disposed in front of said discharge bulb to limit an illumination range of a light beam emitting from said discharge bulb, said shade being supported by said reflector, said shade being made of a conductive material and electrically connected to said socket fixture.
A vehicular lamp, comprising:
- a lamp body;
- a discharge bulb installed within said lamp body;
- a socket for said discharge bulb;
- a connector having an outside surface and connecting to said socket;
- and
- a conductive shield integrally formed with said outside surface and covering substantially all of the outside surface of said connector.
