Abstract:
A lighting device includes an LED light source and a concave reflector. The light source is arranged such that light emitted is reflected by the reflector. The shield is arranged in front of the reflector. A projection lens is arranged to project light passing the shield. In order to efficiently use light emitted from the LED light source and to enable a projected illumination beam of high luminous flux, the LED light source is arranged below an optical axis L of the projection lens.
