The present invention relates to a lighting apparatus for a vehicle, including: a bulb which generates light; a socket in which the bulb is mounted; a reflector which has a socket coupling unit to which the socket is coupled, allows the bulb to be inserted into the reflector, and reflects forward light generated by the bulb; and an electromagnetic shield which is disposed between the socket and the socket coupling unit, and has a bulb through hole which the bulb penetrates, in which first ground contact protrusions, which protrude toward a center of the bulb through hole and come into ground contact with the socket and the socket coupling unit, are formed on a portion of the electromagnetic shield where the bulb through hole is formed.

A vehicle lamp is provided. The vehicle lamp includes a base, a first reflection structure, a second reflection structure, a first light emitting structure, a second light emitting structure, and a lens structure. The first reflection structure and second reflection structure are disposed on the base. The first reflection structure includes at least one first focal point and at least one second focal point. The second reflection structure includes a first focal point and a second focal point. The first light emitting structure and the second light emitting structure are disposed on the base. The lens structure includes a lens optical axis and a lens focal point.

A lamp is disclosed. In an embodiment, the lamp includes a first light source and a second light source embodied as a light-emitting reflector, with a reflective layer and an electroluminescent layer sequence. The second light source is deformable such that an emission pattern of light emitted by the first light source and reflected by the light-emitting reflector is modifiable.

The present invention relates to a high-intensity discharge lamp (1) comprising a discharge vessel (2) enclosing a filling in a discharge chamber (3), and a pair of electrode rods (4, 5) being formed of a material which is free of thorium and protruding from opposite sides into the discharge chamber (3). The diameter ED of the electrode rods (4, 5) in the discharge chamber (3) N satisfies the formula (I), wherein W represents the value of the nominal lamp power in mW and Ed represents the value of the distance of the electrode rods (4, 5) in the discharge chamber (3) in mm, and wherein the nominal lamp power W is between 20 W and 50 W. With the above formula, high-intensity discharge lamps can be easily designed with different nominal powers and/or 10 electrode distances without time consuming experiments in order to achieve an optimum performance.
