    DISCLOSURE FIELD
    [001] This patent generally refers to lighting systems and more specifically to motion detection platform lighting systems. FUNDAMENTALS
    [002] Some building loading platforms include an exterior door with a raised platform for loading and unloading vehicles such as trucks and trailers. To compensate for height differences between the loading dock platform and an adjacent truck or trailer body, many loading docks have a dock leveler. Some platform levelers include a platform or ramp that is pivotally pivoted along its rear edge to vary the height of its front edge. An extension plate or flap extends outward from the front edge of the platform to span the gap and thus create a bridge between the rear of the truck body and the front edge of the platform. This allows material handling equipment and personnel to easily move in and out of the vehicle during loading and unloading operations.
    [003] If the truck or trailer is closed, as opposed to an open-body trailer, the interior of the trailer can be quite dark, making it difficult to see deeply into the trailer. Thus, a light pointing towards the trailer can be installed and used close to the building's door. These light fixtures are available in various shapes and sizes. BRIEF DESCRIPTION OF THE DRAWINGS

    [015] An example lighting system 10 and associated methods, shown in Figures 1 to 11, comprise a lamp 12 for illuminating the interior of a vehicle 14 (e.g. a truck or a trailer) parked on a loading platform 16 of a building 18. In the illustrated example, the lamp 12 is installed somewhere in relation to an entrance door 20 and a loading leveler 22 that gives access between the vehicle 14 and the interior of the building 18. To prevent the lamp from 12 projects excessively bright light directly into the eyes of, for example, a person driving a forklift in the vehicle 14 towards the lamp 12, the lighting system 10 includes a motion detection system 24 to determine whether a body 26 (for example , a material handling device 28, person, etc.) is traveling further into or out of the vehicle 14 and to provide an operating signal 30 indicating the direction of displacement of the body. Lamp 12 is operatively connected in signal communication with motion detection system 24 so as to receive operating signal 30 from motion detection system 24 and dim or redirect light output from lamp 32 when the body 26 moves to the lamp 12
    [016] In some examples, the motion detection system 24 is a component or system of components that detects the presence of a moving body or object that is spaced from the motion detection system itself. Examples of the motion detection system 24 include, but are not limited to, a video camera with analysis, a microphone with analysis, one or more photoelectric eyes, an ultrasound sensor, a microwave sensor, a passive infrared sensor, a radar, etc. .
    [017] In response to the operating signal 30 indicating that the body 26 has undergone a change in the direction of travel, a controller 34 automatically switches the lamp 12 between a first lighting mode and a second lighting mode. In the first lighting mode, illustrated in Figures 1 and 3, lamp projects more light (e.g. light output 32a and 32c) towards body 26 as body 26 moves in a forward direction 36 further inward. of the vehicle 14. In the second lighting mode, illustrated in Figures 2 and 4, the lamp 12 projects less light (e.g. light output 32b and 32d) towards the body 26 when the body 26 is traveling in a reverse direction 38 towards lamp 12.
    [018] In the example shown in Figures 1 and 2, lamp12 projects more lumens in the first lighting mode (Figure 1) than in the second lighting mode (Figure 2). In some examples, this is achieved by providing the lamp 12 with a plurality of light-emitting elements 40 (e.g., light-emitting diodes, LEDs, incandescent lamps, fluorescent lamps, etc.) and further energizing them during the first mode. lighting than during the second lighting mode. In addition or alternatively, more electrical power is supplied to the one or more light emitting elements 40 during the first lighting mode than during the second lighting mode.
    [019] The specific details and component layout of controller 34, lamp 12 and motion detection system 24 may vary. In some examples, the motion detection system 24 comprises a Colibri universal motion sensor for automatic doors. Colibri motion sensors are supplied by BEA SA (a HALMA company) of Angleur, Belgium. In some examples, lamp 12 comprises an array of six LEDs and optics (Cree XTE) supplied by Cree of Durham, NC. Controller 34 may be implemented by digital or analog electrical circuitry, logic circuitry and/or microprocessor with appropriate inputs and outputs for controlling lamp 12 in response to input from motion detection system 24. In some examples, at least one part of the controller 34 is physically incorporated within the lamp 12. In some examples, at least a part of the controller 34 is housed within a mounting base 42 of the lamp 12. In some examples, at least a part of the controller 34 is located contained within a separate housing and is connected in wired or wireless communication with lamp 12 and motion detection system 24. In some examples, light emitting elements 40 and motion detection system 24 are incorporated physically inside the lamp 12 and share a common housing 12'.
    [020] In some examples, the lighting system controller 34 includes a user adjustment input 44 to facilitate changing the brightness of the first and second lighting modes. In some examples, user adjustment input 44 allows a user to vary the lamp's delta brightness between the first and second lighting modes (e.g., correspondingly increasing or decreasing the brightness of the first and second modes by a common value). Examples of user adjustment 44 include, but are not limited to, a potentiometer, a button, a dial, a switch, a touch screen, and a push button.
    [021] In the example shown in Figures 3 and 4, lamp 12 projects light output 32c as a high beam in a first direction 46 during the first lighting mode (Figure 3) and projects light output 32d as a low beam in a second direction 48 during the second lighting mode (Figure 4), wherein the first and second directions 46 and 48 deviate angularly.
    [022] Referring to Figure 5, to avoid a potential collision between the body 26 exiting the vehicle 14 and a peripheral body 50 beyond the vehicle 14 (for example, inside the building 18), some examples of the detection system of motion 24 include a peripheral body sensor 52 (e.g. passive infrared sensor, ultrasonic sensors, microwave sensor, photoelectric eye, video analytics camera, etc.). Examples of peripheral body 50 include, but are not limited to, a person, a material handling device, and a moving or stationary object. Peripheral body sensor 52 provides an alarm signal 54 in response to detection of the presence or movement of peripheral body 50 near input port 20. Lamp 12 is operatively connected in signal communication with peripheral body sensor 52, so that to receive an alarm signal 54. In response to receiving an alarm signal 54, the controller 32 turns off the lamp 12 for a third lighting mode, as shown in Figure 5. In the third lighting mode, the lamp 12 projects a light of alarm 56 for vehicle 14. The alarm light 56 of the third lighting mode is distinguishable from the light projected during the first and second lighting modes. Examples of the alarm light 56 include, but are not limited to, a colored light, a flashing light, and a moving light.
    [023] With reference to Figure 6, to make it easier to adjust the objective (e.g. the direction of light) or other characteristics of the lighting system 10, an articulated arm 58 connects the lamp 12 to the mounting base 42, which by it is in turn connected to a track 60 which, in the illustrated example, is attached to the building 18. The base 42 mounted on the track 60 allows one to manually lower 62 the base 42 to where adjustments can be made more quickly. After adjusting the lighting system 10, the person can return the lamp 12 64 to its normally elevated position in the lane 60.
    [024] In some examples, to save energy, the motion detection system 24 provides a quiescent signal 66 in response to the detection of a lack of motion for a threshold time period inside the vehicle 14, as shown in Figure 7. If the motion detection system 24 does not detect any appreciable movement during the threshold time period (e.g., ten minutes), the lamp 12 is turned off or provides a reduction in light output in response to the quiescent signal 66.
    [025] Referring back to Figure 1, in addition or alternatively, some examples of motion detection system 24 comprise an input/output sensor 68 (e.g. two photoelectric eyes projecting through two beams across the width of the door input 20) which provides an input signal 70 in response to the body 26 (e.g. material handling device 28) entering the vehicle 14 and providing an output signal 72 in response to the body 26 (e.g. the device handling device 28) exiting vehicle 14. The sequence in which the two sensor beams 68 are interrupted indicates the direction in which the body 26 (e.g. material handling device 28) passes through the inlet port 20. In In some examples, signals 70 and 72 determining that body 26 has just entered vehicle 14 trigger controller 34 to command lamp 12 to operate in the first lighting mode. In some examples, signals 70 and 72 determining that body 26 has entered vehicle 14, in combination with detection of a lack of movement in vehicle 14 indicating that body 26 is about to reverse direction, triggers controller 34 to command lamp 12 to stop. switch from the first lighting mode to the second lighting mode.
    [026] Referring to Figures 8 and 9, in some examples, the articulated arm 58 comprises a plurality of links 74 interconnected through a plurality of articulated joints 76. In some examples, a fastener 78 (e.g., a screw) with a adjustable degree of tightness provides means for adjusting the degree of tightness of the plurality of ball joints 76.
    [027] In some examples, a locking element 80 (eg, a pin or bolt) may be installed to lock a chosen joint 76a at a desired angle. Figure 8 shows the locking element 80 selectively movable to an installed position 82 to inhibit joint 76a from pivoting and a removed position 84 to provide joint 76a with freedom of articulation.
    [028] In some examples, the lighting system 10 includes a motorized actuator 85 connected to move the lamp 12 and articulated arm 58 selectively between a stored position (e.g., Figure 7) and an implanted position (e.g., Figures 1 to 5). This provides the option of storing the lamp 12 in a position where it does not obstruct the inlet port 20 or interfere with the operation of a port in the inlet port 20. In some examples, the motorized actuator 85 is operated automatically with the actuation of the port. . For example, the lamp 12 moves to the stowed position when the door begins to close and moves to the deployed position when the door is fully open. Examples of the motorized actuator 85 include, but are not limited to, an electric motor, a hydraulic motor, an air motor, a linear motor, a solenoid, a gear motor, and a hydraulic or pneumatic cylinder.
    [029] In some examples, the articulated arm 58 can be mounted in different configurations to define the direction of the freedom of articulation arm at each joint. Figure 9, for example, shows a first link 74a rotated about ninety degrees with respect to all other links 74, including a second link 74b. The first link 74a is pivoted about a first axis 86, and the second link 74b is pivoted about a second axis 87. The first axle 86 is substantially perpendicular to the second axle 87. The first link 74a is prevented from pivoting in about a third axis 88 that is perpendicular to and intersects the first axis 86. The second connection 74b is inhibited from pivoting about a fourth axis 90 that is perpendicular to and intersects the second axis 87.
    [030] An example lighting system method pertaining to lighting system 10 is illustrated by a block diagram 92 shown in Figure 10. Block 94 represents projecting light output 32 from lamp 12. Block 96 represents detecting body 26 moving relative to lamp 12. Block 98 represents determining whether body 26 is moving closer or further away from lamp 12. Block 100 represents adjusting light output 32. Figures 1 to 4 illustrate adjusting output of light over a chosen brightness range or delta. In some examples, the range chosen includes the range ranging from, but is not limited to, beam high to low, bright to dim, etc. Arrow 102 of Figure 8 represents adjusting the chosen range.
    [031] Another example lighting system method pertaining to lighting system 10 is illustrated by a block diagram 104 shown in Figure 11. Block 106 represents body 26 (e.g. material handling device 28) entering vehicle 14. Block 108 represents detecting sensor 26 (e.g. material handling device 28) moving in forward direction 36 further into vehicle 14. Block 110 represents detecting body 26 (e.g. material handling device 28) moving in reverse direction 38. Block 112 represents lamp 12 projecting more light in primary direction 114 when body 26 (e.g. material handling device 28) is moving in forward direction 36 further into the vehicle 14 than when the body 26 (e.g. material handling device 28) is moving in the reverse direction 38.
    [032] The example lighting systems described here for use on a loading dock where a material handling device is used to load or unload a vehicle parked on the loading dock includes a motion detection system to be moved away from the handling device of material. The motion detection system of some examples is to provide an operating signal in response to the material handling device undergoing a change in the direction of travel within the vehicle. Some exemplary lighting systems also include a lamp to be operatively connected in signal communication with the motion detection system in order to receive the operating signal from the motion detection system. In some examples, the lamp has a first lighting mode and a second lighting mode, and the lamp must switch between the first lighting mode and the second lighting mode in response to the operating signal.
    [033] In some examples, change in direction of travel refers to the material handling device moving in a first direction further into the vehicle and a second direction opposite the first direction. In some examples, the lamp must project more light when the lamp is in the first lighting mode than when the lamp is in the second lighting mode. In some examples, the lamp includes a plurality of light-emitting elements. In some examples, a greater number of the plurality of light emitting elements must emit light when the lamp is in the first lighting mode than when the lamp is in the second lighting mode. In some examples, the lamp in the first lighting mode must project light in a first direction and the lamp in the second lighting mode must project light in a second direction, the first direction being different from the second direction.
    [034] In some examples, the lighting system even includes a user adjustment input associated with the lamp. User adjustment input in some of these examples should make it easy to change a brightness of the first lighting mode and correspondingly change a brightness of the second lighting mode. In some examples, the motion detection system includes an input/output sensor to provide an input signal in response to the material handling device entering the vehicle and to provide an output signal in response to the material handling device. leaving the vehicle. In some examples, the motion detection system must provide a signal in response to the motion detection system detecting a lack of motion over a threshold time period. In some examples, the lamp must reduce a light output in response to the signal. In some examples, the motion detection system may include a peripheral body sensor positioned to detect a peripheral body in addition to the vehicle. The peripheral body sensor in such examples must provide an alarm signal in response to detection of the peripheral body beyond the vehicle. In some examples, the lamp must be in signal communication with the peripheral body sensor in order to receive the alarm signal from the peripheral body sensor. In some examples, the lamp has a third lighting mode distinguishable from the first lighting mode and the second lighting mode, and the lamp to switch to the third lighting mode in response to the alarm signal.
    [035] In some examples, the lighting system also includes an articulated arm to support the lamp. In some examples, the articulated arm includes a plurality of links interconnected by means of a plurality of articulated joints. Some example lighting systems also include a lock having an installed position and a removed position. In these examples, the lock in the removed position must be moved away from the articulated arm and must provide a first joint of the plurality of articulated joints with freedom of articulation. In these examples, the lock in the installed position should engage the articulated arm and inhibit pivoting movement of the first joint. In some examples, the lighting system further includes an articulated arm to support the lamp. The articulated arm includes a plurality of links interconnected by means of a plurality of articulated joints. In some examples, ball joints have an adjustable degree of tightness. The lighting system, in some examples, further includes fasteners at corresponding knuckles of the plurality of knuckles, the fastener for determining the degree of tightness of a corresponding one of the knuckles. In some examples, the lighting system further includes a swivel arm to support the lamp, the swivel arm including a plurality of links interconnected by means of a plurality of swivel joints. In some examples, the plurality of links includes a first link pivoted about a first axis and a second link pivoted about a second axis. The first axis of some examples is substantially perpendicular to the second axis. In some examples, the first link is inhibited from pivoting about a third axis perpendicular to and intercepting the first axis and the second link is inhibited from pivoting about a fourth axis perpendicular to and intercepting the second axis.
    [036] In some examples, the lighting system includes a track to be fixed to a wall of the loading platform and a base to be mounted on the track and movable vertically in relation to the track. In some examples, the lighting system also includes an articulated arm for attaching the lamp to the base. In some examples, the articulated arm includes a plurality of links interconnected by means of a plurality of articulated joints. In some examples, the lighting system includes an articulated arm to support the lamp. The articulated arm in some of these examples includes a plurality of links interconnected by means of a plurality of articulated joints. In some examples, the lighting system also includes a motorized actuator to be coupled to the articulated arm. In some examples, the lamp and articulated arm must be selectively movable by the motorized actuator to a stored position and an implanted position. In some examples, the lamp includes a housing containing both a light emitting element and the motion detection system.
    [037] Some example methods include projecting a light output from a lamp. Some example methods even include detecting a body moving relative to the light bulb. Some example methods even include determining whether the body is moving closer to or further away from the lamp. Some example methods also include adjusting the light output depending on whether the body moves closer to or further away from the lamp. Some of such examples even include projecting more light when the body is moving farther from the lamp than when the body is moving closer to the light. Some example methods include aiming the light output higher when the body is moving farther from the lamp than when the body is moving closer to the light. In some examples, the disclosed methods also include adjusting the light output over a chosen range; and adjust the chosen range. Some exemplary methods include detection of lack of motion over a threshold time period. In some examples, the methods even include projecting more light when the body moves farther from the lamp than when the body is moving closer to the light. Some examples of such methods include projecting more light when the body is moving closer to the light than when there is a lack of movement after the threshold time period. Some example methods include projecting the light output to a vehicle. Some example methods further include detecting a peripheral body in addition to the vehicle. In some such examples methods also include, in response to detection of the peripheral body other than the vehicle, projecting an alarm light onto the vehicle.
    [038] Other example methods for use on a loading dock where a material handling device is used to transport cargo in relation to a vehicle parked on the loading dock include detecting the material handling device moving in a first direction further into the vehicle. Some example detection methods further include the material handling device moving in a second direction opposite to the first direction. Some example methods additionally include projecting a light output from a lamp into the vehicle. In some examples, the lamp is spaced from the vehicle. In some examples, the lamp projects more light when the material handling device is moving in the first direction than when the material handling device is moving in the second direction.
    [039] Some example methods even include aiming the light output higher when the material handling device is moving farther from the lamp than when the material handling device is moving closer to the lamp. Some example methods even include detecting a lack of motion over a threshold period. Some example methods additionally include projecting more light when the material handling device is moving farther from the lamp than when the material handling device is moving closer to the lamp. Some example methods additionally include projecting more light when the material handling device is approaching the lamp than when there is no motion after the threshold period. Some example methods further include detecting a peripheral body in addition to the vehicle. Some such example methods also include an alarm light projecting into the vehicle.
