Vehicular lamp
A vehicular lamp includes a light source, a mirror unit that emits a scanning light beam by reflecting a light beam from the light source by reciprocating rotation around two axes, a reflection type phosphor unit that receives the scanning light beam from the mirror unit to produce an image on a phosphor surface, and a projection lens unit that is disposed to face the phosphor surface of the reflection type phosphor unit and through which light emitted from the image incident from the reflection type phosphor unit passes. The projection lens unit has a bottom surface on the inner side and a chamfered surface on the outer side in a radial direction on the incident side.
Projection system and vehicle with a projection system
A projection system for a vehicle, in particular for an ambient lighting device for generating a plurality of light cones for illuminating the ground in the surroundings of the vehicle, includes at least one light source and a microlens array. The microlens array includes an optical axis, a first portion with at least one first channel and a second portion with at least one second channel.
