Description

MARKING LIGHT ARRANGEMENT FOR A VEHICLE TECHNICAL FIELD The invention relates to a marking light arrangement for a vehicle and a vehicle comprising such a marking light arrangement.
BACKGROUND AND PRIOR ART A marking light arrangement, such as a rear corner marker light on a truck or a bus, may emit light in both the forward and rearward direction. The color of the emitted light in the forward direction may be white and the emitted light in the rearward direction may be red.
Vehicles, such as trucks or buses may also be provided with a reversing light which may emit light in white color. The reversing light may be turned on when the vehicle is driven in the rearward direction. When the vehicle is driven in the forward direction the reversing light may be put out, so that no reversing light is emitted in the rearward direction.
Document US2012/0299476 A1 discloses a vehicle signal light assembly which includes a color mixing light source. The color mixing light source may comprise a plurality of light emitting diodes of at least two constituent colors.
SUMMARY OF THE INVENTION Driving a vehicle, such as a passenger car or a heavy vehicle, e.g. a truck or a bus, in a reverse direction in poor lighting conditions may be complicated for the driver due to poor visibility behind the vehicle.
Installing additional reversing lights at the rear part of the vehicle may be possible, but may require extra wiring, drilling of holes for mounting and may be problematic to install due to legal requirements regarding maximum vehicle length, number of light points on the vehicle, etc.
There is a need to develop a marking light arrangement for a vehicle which may increase the visibility when driving the vehicle in the reverse direction.
The object of the invention is therefore to further develop a marking light arrangement for a vehicle which may increase the visibility when driving the vehicle in the reverse direction.
These objects are achieved with the above-mentioned marking light arrangement for a vehicle according to the appended claims.
According to an aspect of the invention the marking light arrangement for a vehicle may comprise at least one light source for emitting light in a first and second direction and a support element for mounting the marking light arrangement on a surface. The marking light arrangement may be provided with a control device for changing colour of the emitted light in one of the first and second direction.
Such marking light arrangement for a vehicle enables an increased visibility for the driver in the rearward direction of the vehicle when driving the vehicle in the reverse direction.
The marking light arrangement may emit light in the first and second direction. However, the control device of the marking light arrangement may change colour of the emitted light in one of the first and second directions. If the light emitted in the first direction is white and the light emitted in the second direction is red, the first direction may coincide with the forward direction of the vehicle and the second direction may coincide with the rearward direction of the vehicle. However, when reversing the vehicle the control device may change colour of the emitted light in the second direction from red to white colour, so that the area behind the vehicle is illuminated by the white coloured light emitted by the marking light arrangement in the rearward direction. As a result, the white coloured light emitted by the marking light arrangement in the rearward direction may increase the visibility when driving the vehicle in the reverse direction.
However, the control device may change colour of the emitted light in the second direction from red to white colour only under poor visibility conditions or e.g. darkness. The white coloured light emitted by the marking light arrangement in the rearward direction may be additional reversing lights to the ordinary reversing lights of the vehicle for reversing the vehicle in darkness.
Heavy vehicles, such as trucks or buses, may already be provided with side marker indicator lights, side outline marker lights or rear corner marker lights. If there already are such light arrangements present on these kinds of vehicles, these light arrangements may be replaced by the marking light arrangement according to the invention in order to achieve additional reversing lights for reversing the vehicle in darkness. Using already present and approved light arrangements on the vehicle facilitates the possibility to convert or replace these present light arrangements by means of the marking light arrangement according to the invention.
According to a further aspect of the invention the control device may be the at least one light source which may have the ability to change colour.
The light source may be a light emitting diode which may be designed to change colour. The light source may be connected to an electronic control arrangement which controls the light source so that light in a particular colour may be emitted from the light source depending on the direction of movement of the vehicle and also of the conditions visibility around the vehicle. In poor visibility conditions or e.g. darkness the colour of the light source may be switched to white colour so that the visibility may be increased when driving the vehicle in the reverse direction.
According to a further aspect of the invention the at least one light source may be arranged to change colour between white and red colour.
The light emitted in the second direction may be red and second direction may coincide with the rearward direction of the vehicle. When reversing the vehicle the light source may be arranged to change colour from red to white colour, so that the area behind the vehicle may be illuminated by the white coloured light emitted by the light source in the rearward direction. As a result, the white coloured light emitted by the light source in the rearward direction may increase the visibility when driving the vehicle in the reverse direction.
According to a further aspect of the invention the marking light arrangement may comprise a housing, which may accommodate the at least one light source.
The housing may accommodate one light source or a number of light sources. The housing may be designed to permit the at least one light source to emit light in the first and second direction. Also, the housing may be designed to interact with the support element for mounting the marking light arrangement on the surface. The housing may also be designed to interact with the control device for changing colour of the emitted light.
According to a further aspect of the invention the control device for changing colour of the emitted light may be at least one lens arrangement for the emitted light in either one or both of the first and second directions.
Such first and second lens arrangements for the emitted light may be arranged at the light source, so that the light emitted by the light source may pass through the lens arrangement. The colour of the first and second lens arrangements may be changed depending on the direction of movement of the vehicle and also of the conditions of visibility around the vehicle. In poor visibility conditions, such as darkness, the colour of the second lens arrangement for the emitted light in the second direction may be switched from red to white colour so that the visibility when driving the vehicle in the reverse direction may increase.
According to a further aspect of the invention the at least one lens arrangement may have at least two fields of different colours, and changing colour of the emitted light may be provided by rotating the lens.
Such rotating lens arrangement may be transparent for light and may be controlled to be rotated or pivoted within 360° when driving the vehicle in the reverse direction. An electrical motor or another actuating member may be connected to the lens for rotation of the lens. When the vehicle is driven in the forward direction the emitted light from the light source may pass a red field of the lens. Depending on the direction of movement of the vehicle and also of the conditions of visibility around the vehicle the emitted light from the marking light arrangement may be changed. When a reverse gear in the vehicle is engaged the rotating lens arrangement may be rotated so that a field of white colour is placed in front of the light source so that light of white colour may be emitted from the marking light arrangement in the rearward direction. Thus, the visibility behind the vehicle when driving the vehicle in the reverse direction may increase.
According to a further aspect of the invention at least one lens arrangement may be provided with a displaceable transparent element in a colour different from the colour of the lens, and changing colour of the emitted light may be provided by displacing the displaceable transparent element.
Such displaceable transparent element may be controlled to be axially displaced when driving the vehicle in the reverse direction. An electrical motor or another actuating member may be connected to the displaceable transparent element for the displacement of the displaceable transparent element. When the vehicle is driven in the forward direction the emitted light from the light source may pass the displaceable transparent element which may have a red colour. Depending on the direction of movement of the vehicle and also of the conditions of visibility around the vehicle the emitted light from the marking light arrangement may be changed. When a reverse gear in the vehicle is engaged the displaceable transparent element may be displaced from the light source so that the light emitted from the light source may pass through a field of white colour of the lens arrangement, which may be situated in front of the light source so that light of white colour may be emitted from the marking light arrangement in the rearward direction. Thus, the visibility behind the vehicle when driving the vehicle in the reverse direction may increase.
According to a further aspect of the invention the control device may comprise a first and a second light source which first light source may emit light in the first direction and the second light source may emit light in the second direction.
When two light sources are used they may be controlled individually and independent of each other. They may be arranged to emit light in different colors. Also, they may emit light with different intensity or there may be possible to control the intensity individually of the two light sources. One or both light sources may also be a lights source that may be arranged to change colors, such as light emitting diodes that may be arranged to change colors.
According to a further aspect of the invention the control devicemay comprise a third light source for emitting light in the second direction, which third light source may emit light with higher intensity than the second light source.
The third light source may have a different colour than the second light source. The third light source may only be activated when a reverse gear in the vehicle is engaged. If the third light source has a white colour the area behind the vehicle may be illuminated by the white coloured light emitted by the third light source in the rearward direction. As a result, the white coloured light emitted by the third light source in the rearward direction may increase the visibility when driving the vehicle in the reverse direction. The second light source may be arranged to emit light in different colors and with different intensity. The second light source may be a light emitting diode that may be arranged to change colors.
According to a further aspect of the invention the marking light arrangement may be pivotable, so that light emitted in the first direction may be emitted in the second direction and light emitted in the second direction may be emitted in the first direction.
By pivoting the marking light arrangement in about 180° the light emitted in the first direction may after pivoting of the marking light arrangement be emitted in the opposite direction, i.e. the second direction. This may be the same situation for the light, which before the pivoting of the marking light arrangement, is emitted in the second direction. Thus, the light emitted in the second direction may after pivoting of the marking light arrangement be emitted in the opposite direction, i.e. the first direction. The control device of the marking light arrangement for changing colour of the emitted light in one of the first and second direction may in this aspect be the pivotable motion or pivotal ability of the marking light arrangement. The housing may be pivotable in the relation to the support element. The housing may accommodate one light source or a number of light sources. The housing may be designed to permit the at least one light source to emit light in the first and second direction. Also, the housing may be designed to interact with the support element for mounting the marking light arrangement on the surface. The housing may thus be designed to interact with the control device for changing colour of the emitted light by pivoting the housing so that light emitted in the first direction may after pivoting of the housing be emitted in the opposite direction, i.e. the second direction. This may be the same situation for the light, which before the pivoting of the housing, is emitted in the second direction. Thus, the light emitted in the second direction may after pivoting of the housing be emitted in the opposite direction, i.e. the first direction. When engaging a reverse gear in the vehicle an electric motor or another type of actuator connected to the marking light arrangement or the housing of the marking light arrangement may pivot the marking light arrangement or the housing of the marking light arrangement. If the light emitted in the first direction is white and the light emitted in the second direction is red, the first direction may coincide with the forward direction of the vehicle the second direction may coincide with the rearward direction of the vehicle. However, when reversing the vehicle by for example engaging a reverse gear in the vehicle, the marking light arrangement may be pivoted so that the emitted light in the second direction may be changed from red to white colour, which may result in that the area behind the vehicle is illuminated by the white coloured light emitted by the marking light arrangement in the rearward direction. As a result, the white coloured light emitted by the marking light arrangement in the rearward direction may increase the visibility when driving the vehicle in the reverse direction.
According to a further aspect of the invention the marking light arrangement may be a rear corner marker light which may be mounted at a rear corner of the vehicle.
Such a rear corner marker light indicates the position of the rear corner of the vehicle and may be a guidance for the driver of the vehicle to be aware of the position of the rear corner of the vehicle when driving the vehicle. When reversing the vehicle the control device may change colour of the emitted light in the second direction from red to white colour, so that the area behind the vehicle is illuminated by the white coloured light emitted by the rear corner marker light in the rearward direction. As a result, the white coloured light emitted by the rear corner marker light in the rearward direction may increase the visibility when driving the vehicle in the reverse direction.
The above-mentioned objects are also achieved by a vehicle comprising such a marking light arrangement according to the appended claims.
According to a further aspect of the invention a method of emitting light from a marking light arrangement for a vehicle comprises the steps of: a) engaging a reverse gear in the vehicle; and b) changing colour of the light emitted from the marking light arrangement in at least one of the first and second direction.
Such method of emitting light from the marking light arrangement for a vehicle may enable an increased visibility for the driver in the rearward direction of the vehicle when driving the vehicle in the reverse direction. When engaging a reverse gear in the vehicle or when some other activity is made that indicates that the vehicle may be driven in the rearward direction the colour of the light emitted from the marking light arrangement may be changed in at least one of the first and second direction. At least one light source may be arranged at the marking light arrangement for emitting light in a first and second direction. If the second direction coincides with the rearward direction of the vehicle the colour of the light emitted from the marking light arrangement in the second direction may be changed from red to white colour when an indication is received that the vehicle may be driven in the reverse direction. The visibility for the driver in the rearward direction of the vehicle may be increased when the colour of the light emitted from the marking light arrangement in the reverse direction is changed from red to white. However, the colour of the emitted light in the second direction from red to white colour may be changed only under poor visibility conditions or e.g. darkness. The white coloured light emitted by the marking light arrangement in the rearward direction may be additional reversing lights to the ordinary reversing lights of the vehicle for reversing the vehicle in darkness.
The marking light arrangement may be provided with a mounting arrangement for mounting the marking light arrangement at a surface, such as the surface of a body of the vehicle. If the marking light arrangement is mounted at a rear corner of the vehicle the marking light arrangement may be a rear corner marker light of the vehicle. Such a rear corner marker light indicates the position of the rear corner of the vehicle and may be a guidance for the driver of the vehicle to be aware of the position of the rear corner of the vehicle when driving the vehicle. When reversing the vehicle the control device may change colour of the emitted light in the second direction from red to white colour, so that the area behind the vehicle is illuminated by the white coloured light emitted by the rear corner marker light in the rearward direction. As a result, the white coloured light emitted by the rear corner marker light in the rearward direction may increase the visibility when driving the vehicle in the reverse direction.
The marking light arrangement may be provided with a control device for changing colour of the emitted light in one of the first and second direction. The control device may be the at least one light source which may have the ability to change colour. The light source may be a light emitting diode which may be designed to change colour. The light source may be connected to an electronic control arrangement which controls the light source so that light in a particular colour may be emitted from the light source depending on the direction of movement of the vehicle and also on the conditions of visibility around the vehicle. The control device for changing colour of the emitted light may also be at least one lens arrangement for the emitted light in either one or both of the first and second directions. The at least one lens arrangement may have at least two fields of different colours, and changing colour of the emitted light may be provided by rotating the lens. As an alternative, the at least one lens arrangement may be provided with a displaceable transparent element in a colour different from the colour of the lens, and changing colour of the emitted light may be provided by displacing the displaceable transparent element. The marking light arrangement may also comprise a first and a second light source which first light source may emit light in the first direction and the second light source may emit light in the second direction. The marking light arrangement may also be pivotable, so that light emitted in the first direction may be emitted in the second direction and light emitted in the second direction may be emitted in the first direction.
According to a further aspect of the invention the method comprises the further step of: c) increasing the intensity of the emitted light from the marking light arrangement in the at least one of the first and second direction.
Increasing the intensity of the emitted light from the marking light arrangement may increase the visibility for the driver when driving the vehicle. When changing colour of the emitted light to a white colour and also increasing the intensity of the emitted light, the area behind the vehicle may be illuminated by the white coloured light emitted in the rearward direction. This may increase the visibility when driving the vehicle in the reverse direction.
Two light sources may be used and controlled individually and independent of each other. They may be arranged to emit light in different colors. Also, they may emit light with different intensity or there may be possible to control the intensity individually of the two light sources. The marking light arrangement may also comprise a third light source for emitting light in the second direction, which third light source may emit light with higher intensity than the second light source. The third light source may have a different colour than the second light source. The third light source may only be activated when a reverse gear in the vehicle is engaged. If the third light source has a white colour the area behind the vehicle may be illuminated by the white coloured light emitted by the third light source in the rearward direction. As a result, the white coloured light emitted by the third light source in the rearward direction may increase the visibility when driving the vehicle in the reverse direction. The second light source may be arranged to emit light in different colors and with different intensity. The second light source may be a light emitting diode that may be arranged to change colors.

DETAILED DESCRIPTION OF THE DRAWINGS Fig. 1 schematically illustrates a side view of a vehicle 1, provided with a marking light arrangement 2 according to the invention. The vehicle 1 may be provided with driver and passenger compartment 4 arranged on a chassis 6 of the vehicle 1. Also, the vehicle 1 may be provided with a powertrain 8, which comprises an internal combustion engine 10, a gearbox 12, and a propeller shaft 14. The gearbox 12 may be connected to drive wheels 16 via a propeller shaft 14. The vehicle 1 may be a heavy vehicle, e.g. a truck or a bus. The vehicle 1 may alternatively be a passenger car. The vehicle 1 may be manually operated, remotely operated or autonomously operated. A steering wheel 20 is arranged in the driver and passenger compartment 4. A turning motion of the steering wheel 20 will turn the front wheels 18. Instead of, or together with the steering wheel 20, an electronic control arrangement 22 may be connected to the steering wheel 20 for remotely or autonomously operation of the vehicle 1. The steering wheel 20 may also be connected to the drive wheels 16 of the vehicle 1. Instead of, or in combination with the internal combustion engine 10, an electric engine 23 may be connected to the powertrain 8. The marking light arrangement 2 may emit light in a first and second direction. The first direction may coincide with the forward direction of the vehicle 1 and the second direction may coincide with the rearward direction of the vehicle 1. When the vehicle 1 is driven in the forward direction the color of the emitted light in the forward direction may be white and the emitted light in the rearward direction may be red. The marking light arrangement 2 may be connected to a gear lever 25 of the vehicle 1, so when a reverse gear in the vehicle 1 is engaged by means of the gear lever 25 the light emitted by the marking light arrangement 2 in the rearward direction may change to white colour. The marking light arrangement 2 may be a rear corner marker light which may be mounted on a surface 27 of a body 28 of a vehicle 1, at one or both rear corners 30 of the vehicle 1.
Fig. 2 schematically illustrates the marking light arrangement 2 according to an embodiment of the invention. The marking light arrangement 2 may comprise a light source 32 for emitting light in the first and second direction and a support element 38 for mounting the marking light arrangement 2 on a surface 27, such as the surface 27 of the body 28 of the vehicle 1. The marking light arrangement 2 may comprise a housing 40, which may accommodate the at least one light source 32. The housing 40 may accommodate one light source 32 or a number of light sources 32. The housing 40 may be designed to permit the light source 32 to emit light in the first and second direction. Also, the housing 40 may be designed to interact with the support element 38 for mounting the marking light arrangement 2 on the surface 27. The housing 40 may also be designed to interact with a control device for changing colour of the emitted light in one of the first and second direction. The control device may comprise the light source 32 and/or the housing 40. The control device may also comprise an actuator 42, a second light source 34, a third light source 36, a first lens arrangement 44, a second lens arrangement 45, two fields of different colours 46, 47, a displaceable transparent element 48 and/or a lens member 49. These features are explained in more detail below. An electric motor 42 or another type of actuator may be connected to the marking light arrangement 2 or the housing 40 of the marking light arrangement 2. The electric motor 42 or actuator may pivot the marking light arrangement 2 or the housing 40 of the marking light arrangement 2 for changing colour of the emitted light in one of the first and second direction or in both directions.
Fig. 3 shows a section view along the line A-A in fig. 2. When the vehicle 1 is driven in the forward direction the color of the emitted light in the forward direction may be white and the emitted light in the rearward direction may be red. By pivoting the marking light arrangement 2 by means of the electric motor 42 or the actuator, the light emitted in the first direction may be emitted in the second direction and light emitted in the second direction may be emitted in the first direction.
Fig. 4 schematically illustrates the marking light arrangement 2 according to an embodiment of the invention. In fig. 4 the marking light arrangement 2 has been pivoted 180 ° by means of the electric motor 42 or the actuator. By pivoting the marking light arrangement 2 in about 180° the light emitted in the first direction may after pivoting of the marking light arrangement 2 be emitted in the opposite direction, i.e. the second direction. This may be the same situation for the light, which before the pivoting of the marking light arrangement 2, is emitted in the second direction. Thus, the light emitted in the second direction may after pivoting of the marking light arrangement 2 may be emitted in the opposite direction, i.e. the first direction.
The control device of the marking light arrangement 2 for changing colour of the emitted light in one of the first and second direction may in this aspect be the pivotable motion or pivotal ability of the marking light arrangement 2. The housing 40 may be pivotable in the relation to the support element 38. The housing 40 may accommodate one light source 32 or a number of light sources 32. The housing 40 may be designed to permit the at least one light source 32 to emit light in the first and second direction. In fig. 4 the marking light arrangement 2 may comprise a second light source 34 which may emit light in the second direction when the marking light arrangement 2 has been pivoted 180°. When the second light source 34 is directed in the first direction, i.e. in the forward direction of the vehicle 1 the second light source 34 may be put off.
When two light sources 32, 34 are used they may be controlled individually and independent of each other. They may be arranged to emit light in different colors. Also, they may emit light with different intensity or there may be possible to control the intensity individually of the two light sources 32, 34.
Also, the housing 40 may be designed to interact with the support element 38 for mounting the marking light arrangement 2 on the surface 27. The housing 40 may thus be designed to interact with the control device for changing colour of the emitted light by pivoting the housing 40 so that light emitted in the first direction may after pivoting of the housing 40 be emitted in the opposite direction, i.e. the second direction. This may be the same situation for the light, which before the pivoting of the housing 40, is emitted in the second direction. Thus, the light emitted in the second direction may after pivoting of the housing 40 be emitted in the opposite direction, i.e. the first direction. When engaging a reverse gear in the vehicle 1 the electric motor 42 or another type of actuator connected to the marking light arrangement 2 or the housing 40 of the marking light arrangement 2 may pivot the marking light arrangement 2 or the housing 40 of the marking light arrangement 2. If the light emitted in the first direction is white and the light emitted in the second direction is red, the first direction may coincide with the forward direction of the vehicle 1 the second direction may coincide with the rearward direction of the vehicle 1. However, when reversing the vehicle 1 by for example engaging a reverse gear in the vehicle 1, the marking light arrangement 2 may be pivoted so that the emitted light in the second direction may be changed from red to white colour, which may result in that the area behind the vehicle 1 is illuminated by the white coloured light emitted by the marking light arrangement 2 in the rearward direction. As a result, the white coloured light emitted by the marking light arrangement 2 in the rearward direction may increase the visibility when driving the vehicle 1 in the reverse direction.
Fig. 5 schematically illustrates the marking light arrangement 2 according to an embodiment of the invention. In fig. 5 the marking light arrangement 2 has been pivoted 180° by means of the electric motor 42 or the actuator. The marking light arrangement 2 may comprise a first and a second light source 32, 34 which first light source 32 may emit light in the first direction and the second light source 34 may emit light in the second direction. However, when pivoting the marking light arrangement 2 at an angle of 180° the first light source 32 may emit light in the second direction and the second light source 34 may emit light in the first direction. The marking light arrangement 2 may also comprise a third light source 36 for emitting light in the second direction when pivoting the marking light arrangement 2 at an angle of 180°. The third light source 36 may emit light with higher intensity than the first and second light source 32, 34. When the third light source 36 is directed in the first direction, i.e. in the forward direction of the vehicle 1 the third light source 36 may be put off.
When three light sources 32, 34, 36 are used they may be controlled individually and independent of each other. They may be arranged to emit light in different colors. Also, they may emit light with different intensity or there may be the possibility to control the intensity individually of the light sources 32, 34, 36. Instead of arranging the marking light arrangement 2 pivotal the third light source 36 may have a different colour than the second light source 34, and the second and third light sources 34, 36 are directed in the second direction, i.e. the rearward direction of the vehicle 1. The third light source 36 may only be activated when a reverse gear in the vehicle 1 is engaged. The second light source 34 may have red colour and the third light source 36 may have white colour. If the third light source 36 has a white colour the area behind the vehicle 1 may be illuminated by the white coloured light emitted by the third light source 36 in the rearward direction. As a result, the white coloured light emitted by the third light source 36 in the rearward direction may increase the visibility when driving the vehicle 1 in the reverse direction. The second light source 34 may also be a light emitting diode that may be arranged to change colour from red to white colour when driving the vehicle 1 in the reverse direction.
Fig. 6 schematically illustrates the marking light arrangement 2 according to an embodiment of the invention. The control device may be a light source 34 which may be designed to change colour. The light source 34 may be connected to the electronic control arrangement 22 (fig. 1) which controls the light source 34 so that light in a particular colour may be emitted from the light source 34 depending on the direction of movement of the vehicle 1 and also of the conditions visibility around the vehicle 1. In poor visibility conditions or e.g. darkness the colour of the light source 34 may be switched to white colour so that the visibility may be increased when driving the vehicle 1 in the reverse direction. The light source 34 may be arranged to change colour between white and red colour. The light emitted in the second direction may be red and the second direction may coincide with the rearward direction of the vehicle 1. When reversing the vehicle 1 the light source 34 may be arranged to change colour from red to white colour, so that the area behind the vehicle 1 may be illuminated by the white coloured light emitted by the light source 34 in the rearward direction. The light source 34 which may be designed to change colour may be a second light source 34 directed in the second direction, i.e. the rearward direction of the vehicle 1. A first light source 32 may be arranged at the marking light arrangement 2, which first light source 32 may be directed in the first direction, i.e. the forward direction of the vehicle 1.
Fig. 7 schematically illustrates the marking light arrangement 2 according to an embodiment of the invention. The control device for changing colour of the emitted light may be a first and second lens arrangement 44, 45 for the emitted light in either one or both of the first and second directions. The first and second lens arrangement 44, 45 for the emitted light may be arranged at the light source 32, so that the light emitted by the light source 32 may pass through the first and second lens arrangement 44, 45. However, as is illustrated in fig. 7 first and second light sources 32 and 34 may be arranged at the first and second lens arrangement. Light emitted from the first light source may pass through the first lens arrangement 44 and light emitted from the second light source may pass through the second lens arrangement 45. The colour of the first and second lens arrangement 44, 45 may be changed depending on the direction of movement of the vehicle 1 and also of the conditions of visibility around the vehicle 1. In poor visibility conditions, such as darkness, the colour of the second lens arrangement 45 for the emitted light in the second direction may be switched from red to white colour so that the visibility when driving the vehicle 1 in the reverse direction may increase.
As is illustrated in fig. 7 the second lens arrangement 45 may have two fields 46, 47 of different colours, and changing colour of the emitted light may be provided by rotating the second lens arrangement 45. The rotatable second lens arrangement 45 may be transparent for light and may be controlled to be rotated or pivoted within 360° when driving the vehicle 1 in the reverse direction. An electric motor 42 or another actuating member may be connected to the second lens arrangement 45 for rotation of the second lens arrangement 45. When the vehicle 1 is driven in the forward direction the emitted light from the second light source 34 may pass a red field 46 of the second lens arrangement 45, which is illustrated in fig. 7.
Fig. 8 schematically illustrates the marking light arrangement 2 according to an embodiment of the invention. Depending on the direction of movement of the vehicle 1 and also of the conditions of visibility around the vehicle 1 the emitted light from the marking light arrangement 2 may be changed. When a reverse gear in the vehicle 1 is engaged the rotatable second lens arrangement 45 may be rotated so that a field 47 of white colour is placed in front of the second light source 34 so that light of white colour may be emitted from the marking light arrangement 2 in the rearward direction. Thus, the visibility behind the vehicle 1 when driving the vehicle 1 in the reverse direction may increase. In fig. 8 the rotatable second lens arrangement 45 has been rotated or pivoted 180° by means of the electric motor 42 so that the field 47 of white colour is placed in front of the second light source 34 so that light of white colour may be emitted from the marking light arrangement 2 in the rearward direction of the vehicle 1.
Fig. 9 schematically illustrates the marking light arrangement 2 according to an embodiment of the invention. The lens arrangement 45 may be provided with a displaceable transparent element 48 in a colour different from the colour of a lens member 49. Changing colour of the emitted light may be provided by displacing the displaceable transparent element 48. The displaceable transparent element 48 may be controlled to be axially displaced when driving the vehicle 1 in the reverse direction. An electric motor 42 or another actuating member may be connected to the displaceable transparent element 48 for the displacement of the displaceable transparent element 48. When the vehicle 1 is driven in the forward direction the emitted light from the light source 32 may pass the displaceable transparent element 48 which may have a red colour. When driving in the reverse direction the emitted light from the light source 32 may only pass the lens member 49 which may have white colour.
Fig. 10 schematically illustrates the marking light arrangement 2 according to an embodiment of the invention. Depending on the direction of movement of the vehicle 1 and also of the conditions of visibility around the vehicle 1 the emitted light from the marking light arrangement 2 may be changed. When a reverse gear in the vehicle 1 is engaged the displaceable transparent element 48 may be displaced from the light source 32 so that the light emitted from the light source 32 may pass through a field of white colour of the lens member 49 of the lens arrangement 45, which may be situated in front of the light source 32 so that light of white colour may be emitted from the marking light arrangement 2 in the rearward direction. Thus, the visibility behind the vehicle 1 when driving the vehicle 1 in the reverse direction may increase.
Fig. 11 shows a flowchart of a method for emitting light from a marking light arrangement 2 for a vehicle 1. The marking light arrangement 2 may be configured as the marking light arrangement 2 disclosed in figures 1 -10 and thus comprises: at least one light source 32 for emitting light in a first and second direction and a support element 38 for mounting the marking light arrangement 2 at a surface 27. The method comprises the steps of: a) engaging a reverse gear in the vehicle 1; b) changing colour of the light emitted from the marking light arrangement 2 in least one of the first and second direction, and c) increasing the intensity of the emitted light from the marking light arrangement 2 in the at least one of the first and second direction.
Engaging a reverse gear in the vehicle 1 in step a) may be performed by a driver of the vehicle 1 when the vehicle 1 may be driven in the reversed direction. The driver may control a gear lever 25, which may be connected to the marking light arrangement 2 or an electronic control arrangement 22, which is connected to the marking light arrangement 2. A signal may be received by the marking light arrangement 2 when a reverse gear is engaged by the gear lever 25.
Changing colour of the light emitted from the marking light arrangement 2 in least one of the first and second direction in step b) may be performed when the marking light arrangement 2 receives a signal that the reverse gear is engaged by the gear lever 25. Changing colour of the light emitted from the marking light arrangement 2 may be performed as described above.
Increasing the intensity of the emitted light from the marking light arrangement 2 in step c) may be performed by increasing power transmitted to a light source 32 at the marking light arrangement 2 or controlling the light source 32 or the marking light arrangement 2 so that the intensity of the emitted light increases. The increased intensity of the emitted light from the marking light arrangement 2 may increase the visibility for the driver when driving the vehicle 1. When changing colour of the emitted light to a white colour and also increasing the intensity of the emitted light, the area behind the vehicle 1 may be illuminated by the white coloured light emitted in the rearward direction. This may increase the visibility when driving the vehicle 1 in the reverse direction.
The components and features specified above may within the framework of the invention be combined between the different embodiments specified.
