Abstract
A lighting device and a lighting system for a vehicle are provided. The lighting device includes a signal detecting portion which receives a light control direction signal; a control portion which controls a light source according to the light control direction signal; and a lighting state signal generating portion which outputs a lighting state signal based on the light control direction signal received by the signal detecting portion. The lighting system includes the lighting device and a light source.
Claims9
A lighting device for a vehicle comprising:
- a signal detecting portion which receives a light control direction signal;
- a control portion which controls a light source according to the light control direction signal;
- and
- a lighting state signal generating portion which outputs a lighting state signal based on the light control direction signal received by the signal detecting portion.
A lighting system for a vehicle, the lighting system comprising;
- a light source;
- an external control device;
- and
- a lighting device comprising:
- a signal detecting portion which receives a light control direction signal from the external control device;
- a control portion which controls the light source according to the light control direction signal;
- and
- a lighting state signal generating portion which outputs a lighting state signal to the external control device, the lighting state signal generated based on the light control direction signal received by the signal detecting portion.
A lighting system for a vehicle, the lighting system comprising:
- a vehicle headlamp;
- and
- a lighting device comprising:
- a signal detecting circuit which receives a light control direction signal indicating a desired brightness level of the light source;
- a control circuit which controls a brightness level of the light source according to the light control direction signal;
- and
- a lighting state signal circuit which outputs a lighting state signal, the lighting state signal being a pulse cycle indicating the brightness level of the light source when the light source is operating in a normal condition, or a low level when the light source fails.
