Abstract
A dynamic lighting solution for a wheelchair lift is provided. The dynamic lighting solution may include a sensor to ascertain a position of a wheelchair lift platform. The sensor may be electrically coupled to a controller. The controller may be electrically coupled to a light source and configured to adjust a brightness or other lighting parameter of the light source based on the assessment of the position of the lift. The dynamic lighting solution may be configured to dim the light source when the lift platform is above the floor level of the vehicle. This solution prevents direct light from shining in the eye of an operator actuating the wheelchair lift.
Claims20
A dynamic lighting system for a vehicle access device comprising:
- at least one light source configured to illuminate a platform of the vehicle access device;
- at least one sensor configured to ascertain a position characteristic of the platform of the vehicle access device;
- a controller electrically coupled to the at least one light source and the at least one sensor, wherein the controller is configured to adjust at least one lighting parameter of the light source based on the position characteristic.
A passenger vehicle modified to accommodate physically limited passengers, the passenger vehicle comprising a vehicle access device, the vehicle access device having:
- at least one light source configured to illuminate a platform of the vehicle access device;
- at least one sensor configured to ascertain a position characteristic of the platform of the wheelchair lift;
- a controller electrically coupled to the at least one light source and the at least one sensor, wherein the controller is configured to adjust at least one lighting parameter of the light source based on the position characteristic.
A method of adjusting one or more light sources for a vehicle access device comprising:
- ascertaining at least one characteristic representative of a position of a platform of the vehicle access device;
- adjusting a lighting parameter of the one or more light sources when the at least one characteristic indicates that the position of the platform has reached a predetermined position threshold.
