Abstract
A lighting module for use in a lighting device for a vehicle includes at least one projection module for generating a light distribution in the vehicle's environment. At least one light source module is also provided. The projection module contains numerous projection units. The light source module contains numerous light source units. Each projection unit contains at least one projection lens. Each projection unit is dedicated to at least one light source unit. At least two projection lenses from at least two different projection units have different focal lengths.
Claims19
A lighting module for use in a lighting device for a vehicle, the lighting module comprising:
- at least one projection module configured to generate a light distribution in the vehicle's environment, the at least one projection module comprising a plurality of projection units, wherein each projection unit includes at least one projection lens;
- and
- at least one light source module comprising a plurality of light source units,
- wherein each projection unit is dedicated to at least one light source unit,
- wherein at least two projection lenses from at least two different projection units have different focal lengths;
- and
- wherein the lighting module further comprises a control unit configured to control the plurality of light source units, the control unit being configured to switch on, switch off, and/or dim at least one light source of the light source module based at least on a current tilting of the vehicle.
A method for controlling a lighting module for use in a lighting device for a vehicle, the lighting module including at least one projection module configured to generate a light distribution in the vehicle's environment, the at least one projection module including a plurality of projection units, wherein each projection unit includes at least one projection lens, the lighting module also including at least one light source module including a plurality of light source units, wherein each projection unit is dedicated to at least one light source unit, and wherein at least two projection lenses from at least two different projection units have different focal lengths, the method comprising of
- switching on and/or switching off, and/or dimming at least one light source of the light source module based on a current deceleration of the vehicle;
- switching on and/or switching off, and/or dimming at least one light source of the light source module based on a current tilting of the vehicle;
- switching on and/or switching off, and/or dimming at least one light source of the light source module based on a current vehicle speed;
- switching on and/or switching off, and/or dimming at least one light source of the light source module due to oncoming traffic.
A method for controlling a lighting module for use in a lighting device for a vehicle, the lighting module including at least one projection module configured to generate a light distribution in the vehicle's environment, the at least one projection module including a plurality of projection units, wherein each projection unit includes at least one projection lens, the lighting module also including at least one light source module including a plurality of light source units, wherein each projection unit is dedicated to at least one light source unit, and wherein at least two projection lenses from at least two different projection units have different focal lengths, the method comprising at least two of the following steps:
- switching on and/or switching off, and/or dimming at least one light source of the light source module based on a current deceleration of the vehicle;
- switching on and/or switching off, and/or dimming at least one light source of the light source module based on a current tilting of the vehicle;
- switching on and/or switching off, and/or dimming at least one light source of the light source module based on a current vehicle speed;
- switching on and/or switching off, and/or dimming at least one light source of the light source module due to oncoming traffic.
