1. A vehicle lamp comprising:
- a primary light source module having an LED as a light source and a primary light source optical axis along which the LED emits light; and
a primary optical system for distributing light from the primary light source module frontward and toward a primary predetermined area, the primary optical system includinga primary optical system optical axis along which light is directed from the primary optical system,a primary reflector configured to direct light frontward along the primary optical system optical axis,a primary projector lens whose optical axis is located along the primary optical system optical axis, anda primary shading member located substantially at the focus of the primary projector lens to form a cut off of a light distribution pattern to be produced by the vehicle lamp, whereinthe primary light source optical axis is inclined relative to the primary optical system optical axis at an angle different from 90 degrees, andthe primary shading member is an elongate substantially planar member located substantially within a plane that is substantially parallel with the primary optical system optical axis.

Abstract
A vehicle lamp can include a plurality of light source modules each having an LED as a light source, and optical systems for distributing light from each of the light source modules frontward toward predetermined areas or predetermined patterns that are different from each other and which make up a light distribution pattern. Each of the optical systems can be optimized to emit light to a predetermined area, and each of the light source modules'"'"' LEDs can be optimally arranged for each of the corresponding optical systems.

10. A vehicle lamp comprising:
-
a plurality of primary light source modules each having a primary LED as a light source and a shade member located adjacent the primary LED, each of the primary light source modules having a light source optical axis along which each LED emits light; and a primary optical system for distributing light from the primary light source module frontward and toward a primary predetermined area, the primary optical system including a primary optical system optical axis along which light is directed from the primary optical system, and a primary reflector configured to direct light frontward along the primary optical system optical axis;
whereinthe primary light source modules are located about the primary optical system optical axis and configured such that the light source optical axis of each of the primary light source modules extends outward and away from the primary optical system optical axis. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
