The headlamp has multiple lamp units (20,40A,40B,60) each using light-emitting diodes (LED) as light sources. One type of lamp unit (20) uses a reflector and a lens to produce a convergent beam combining direct and reflected light, another type (40A,40B) uses a convergent lens to produce direct illumination, and the third type (60) delivers only reflected light. |
