Ambient lighting system for an agricultural machine
An ambient light controller in an agricultural machine can control multicolor lights arranged in an operator cab of the machine to project light around structures in the cab to areas that are perceivable by a forward facing operator to convey useful information about the machine to the operator. The lights can be projected around such structures by using light pipes. The lights can preferably be in a color which minimizes glare inside the cab to avoid distraction. The light controller can monitor various functions of the machine, such as boom height, and change colors and/or patterns of the lights to indicate states corresponding to the conditions, such as a normal state and a fault state.
1. An ambient lighting system for an agricultural machine, the ambient lighting system comprising:
a plurality of multicolor lights arranged in an operator cab, each multicolor light having a light pipe configured to transport light around a structure in the operator cab to project the light in an interior area of the operator cab so that the light is perceivable by a forward facing operator in the operator cab; and
an ambient lighting controller in communication with the plurality of multicolor lights, the ambient lighting controller executing a program stored in a non-transient medium to:
monitor a plurality of functions of the agricultural machine, the plurality of functions including at least one of operating a spray section of the agricultural machine or positioning of a boom of the agricultural machine;
determine a state from among a plurality of states according to one or more of the monitored functions;
illuminate the plurality of multicolor lights in a first one of a plurality of colors in response to the determined state of the one or more monitored functions, each color of the plurality of colors corresponding to one of the plurality of states of the one or more monitored functions; and
flashing at least a portion of the plurality of multicolor lights in a second one of the plurality of colors in response to determination of a fault state for one of the monitored plurality of functions of the agricultural machine.
2. The ambient lighting system of claim 1 , wherein the plurality of multicolor lights are configured in a rearward portion of the operator cab, behind a forward facing operator.
3. The ambient lighting system of claim 1 , wherein the light pipes are configured to project the light onto an overhead area of the operator cab.
4. The ambient lighting system of claim 1 , wherein at least one light pipe is configured to transport the light around a storage compartment in the operator cab.
5. The ambient lighting system of claim 4 , wherein the storage compartment houses a plurality of electrical fuses for the agricultural machine.
6. The ambient lighting system of claim 1 , wherein each multicolor light comprises a plurality of Light Emitting Diodes (LED's).
7. The ambient lighting system of claim 1 , wherein the ambient lighting controller is configured to control the multicolor lights to project light in at least two colors which minimize glare.
8. The ambient lighting system of claim 7 , wherein the at least two colors which minimize glare are selected from the group consisting of: red, blue, green and yellow.
9. The ambient lighting system of claim 1 , wherein the ambient lighting controller is configured to control the multicolor lights to project light in at least two patterns, including continuously lit and flashing.
10. An agricultural sprayer comprising:
a chassis supported by a plurality of wheels;
a sprayer boom extending transversely relative to the chassis;
an operator cab supported by the chassis, the operator cab including a plurality of multicolor lights, each multicolor light having a light pipe configured to transport light around a structure in the operator cab to project the light in an interior area of the operator cab so that the light is perceivable by a forward facing operator in the operator cab; and
an ambient lighting controller in communication with the plurality of multicolor lights, the ambient lighting controller executing a program stored in a non-transient medium to:
monitor a plurality of functions of the agricultural sprayer, the plurality of functions including at least one of operating a spray section of the agricultural sprayer or positioning of the sprayer boom;
determine a state from among a plurality of states according to one or more of the monitored functions;
illuminate the plurality of multicolor lights in a first one of a plurality of colors in response to the determined state of the one or more monitored functions, each color of the plurality of colors corresponding to one of the plurality of states of the one or more monitored functions; and
flashing at least a portion of the plurality of multicolor lights in a second one of the plurality of colors in response to determination of a fault state for one of the monitored plurality of functions of the agricultural machine.
11. The agricultural sprayer of claim 10 , wherein the plurality of multicolor lights are configured in a rearward portion of the operator cab, behind a forward facing operator.
12. The agricultural sprayer of claim 10 , wherein the light pipes are configured to project the light onto an overhead area of the operator cab.
13. The agricultural sprayer of claim 10 , wherein at least one light pipe is configured to transport the light around a storage compartment in the operator cab.
14. The agricultural sprayer of claim 13 , wherein the storage compartment houses a plurality of electrical fuses for the agricultural sprayer.
15. The agricultural sprayer of claim 10 , wherein each multicolor light comprises a plurality of Light Emitting Diodes (LED's).
16. The agricultural sprayer of claim 10 , wherein the ambient lighting controller is configured to control the multicolor lights to project light in at least two colors which minimize glare.
17. The agricultural sprayer of claim 16 , wherein the at least two colors which minimize glare are selected from the group consisting of: red, blue, green and yellow.
18. The agricultural sprayer of claim 10 , wherein the ambient lighting controller is configured to control the multicolor lights to project light in at least two patterns, including continuously lit and flashing.
