Abstract
A lamp system includes a variable light distribution lamp. The variable light distribution lamp 110 irradiates a beam having a variable light intensity distribution to a road surface. A light distribution controller controls the variable light distribution lamp. In response to the start of a predetermined event, the light distribution controller draws a pattern that corresponds to the event. In response to the end of the event, the light distribution controller extinguishes the pattern.
Claims19
A lamp system comprising:
- a first variable light distribution lamp provided on a front-left side of a vehicle, and structured to irradiate a first beam having a variable light intensity distribution to a road surface so as to draw a first pattern;
- a second variable light distribution lamp provided on a front-right side of the vehicle, and structured to irradiate a second beam having a variable light intensity distribution to the road surface so as to draw a second pattern;
- and
- a light distribution controller structured to control the first variable light distribution lamp and the second variable light distribution lamp such that a combination of the first pattern and the second pattern forms a figure for driving assistance,
- wherein the first pattern and the second pattern respectively include a first figure and a second figure to be superimposed on the road surface,
- and wherein there is an intentional difference between the first figure and the second figure drawn on the road surface in a reference state.
3 more elements
A lamp system comprising:
- a variable light distribution lamp structured to irradiate a beam having a variable light intensity distribution to a road surface;
- a light distribution controller structured to control the variable light distribution lamp when a vehicle mounting the lamp system is traveling, and to draw a figure for driving assistance on the road surface using the beam,
- wherein, when a person who satisfies a predetermined condition approaches the vehicle while the vehicle is parked, the light distribution controller draws a predetermined pattern on a ground surface using the beam.
An automotive lamp comprising:
- a variable light distribution lamp structured to irradiate a beam having a variable light intensity distribution to a road surface;
- and
- a light distribution controller structured to control the variable light distribution lamp, such that the variable light distribution lamp draws a pattern over a predetermined range in front of a vehicle with a traveling direction as a longitudinal direction thereof with a light intensity that is brighter or dimmer than that of a low beam, wherein the pattern is drawn as an animation of a plurality of figures that slide in a direction away from the vehicle at the same speed.
