Abstract
A lighting device for a vehicle includes multiple light emitting devices. Each light emitting device is constructed of a light emitting diode as a light source and a light guide lens for guiding light emitted from the light emitting diode. The light emitting devices are formed in convex light emitting devices and fan-shaped light emitting devices. The convex devices and the fan-shaped devices have different light distribution characteristics. Therefore, light distribution areas and intensity of the lighting device are more flexibly adjusted than other lighting devices using light emitting diodes as light source.
