Abstract
A vehicle lighting device includes: an infrared sensor which detects an object around a vehicle using infrared light; a visible light source which illuminates visible light to the object when the infrared sensor detects the object; a reflection mirror which reflects the infrared light and the visible light to an area around the vehicle; and a light path adjusting mechanism which adjusts light paths of the infrared light and the visible light in a synchronizing manner by rotating the reflection mirror.

A vehicle lighting device comprising:
- an infrared sensor which detects an object around a vehicle using infrared light;
- a visible light source which illuminates visible light to the object when the infrared sensor detects the object;
- a reflection mirror which reflects the infrared light and the visible light to an area around the vehicle;
- and
- a light path adjusting mechanism which adjusts light paths of the infrared light and the visible light in a synchronizing manner by rotating the reflection mirror.
A lighting device for a vehicle comprising:
- an infrared sensor comprising:
- a light emitting portion that emits infrared light;
- and
- a light receiving portion that detects an object around the vehicle based on reflections of the emitted infrared light;
- a visible light source that illuminates visible light to the detected object;
- a reflection mirror that reflects the emitted infrared light and the visible light to an area around the vehicle;
- and
- a light path adjusting mechanism that synchronously adjusts light paths of the emitted infrared light and the visible light by rotating the reflection mirror.
A method of controlling a lighting device for a vehicle comprising:
- emitting infrared light;
- detecting an object around the vehicle based on reflections of the emitted infrared light;
- illuminating visible light to the detected object;
- reflecting the emitted infrared light and the visible light to an area around the vehicle;
- and
- synchronously adjusting light paths of the emitted infrared light and the visible light.
