A dispenser is provided having a nozzle that can direct light down a stream of liquid exiting therefrom. The nozzle includes one or more features to promote a substantially laminar flow of liquid therethrough. This construction can allow the light to travel farther down the stream of liquid exiting the nozzle than in e.g., non-laminar flow. Such light transmission can allow the user to more accurately view the dispenser and liquid flow when filling a container with liquid.

1. A dispenser for dispensing a liquid, comprising: a liquid supply;a nozzle in fluid communication with the liquid supply and defining an axial direction and a radial direction that are orthogonal to each other, the nozzle comprising a first end along the axial direction;a second end downstream and opposite to the first end along the axial direction;a light source having at least a portion positioned between the first end and the second end;an annular liquid flow channel extending longitudinally along the axial direction between the first end to the second end and around the light source, the flow channel configured to promote a substantially laminar flow of liquid;a cone positioned upstream of the light source and in the flow channel, the cone having a tip directed towards the first end; anda plurality of contacts positioned along an outer surface of the nozzle and in electrical communication with the light source, the contacts configured to provide the light source with electrical power. 2. A dispenser as in claim 1, wherein the light source is positioned approximately in the center of the nozzle along the radial direction. 3. A dispenser as in claim 1, wherein the cone has a longitudinal axis that is substantially parallel to the axial direction. 4. A dispenser as in claim 1, wherein the nozzle further comprises a cylindrical channel extending along the axial direction, and wherein at least a portion of the light source is positioned in the cylindrical channel. 5. A dispenser as in claim 1, wherein the nozzle further comprises a first component and a separate second component. 6. A dispenser as in claim 1, wherein the flow channel defines a straight section, and wherein the straight section defines a length of at least about 0.01 meters, such that a liquid traveling therethrough has a Reynolds number in the range of about 2500 to about 700. 7. A dispenser as in claim 1, wherein the nozzle further comprises a tip positioned at the second end of the nozzle, and wherein at least a portion of the tip is comprised of a transparent material or translucent material. 8. A dispenser as in claim 1, wherein the nozzle further comprises a tip positioned at the second end of the nozzle, and wherein the tip comprises a plurality of ribs extending along the axial direction and configured to promote a laminar flow of liquid. 9. A dispenser as in claim 1, wherein the nozzle further comprises an attachment portion positioned at the first end, the attachment portion defining a seal for connection with the liquid supply. 10. A dispenser as in claim 1, wherein the nozzle is releasably connected to the liquid supply. 11. A dispenser as in claim 1, wherein the light source comprises a light emitting diode. 12. A dispenser as in claim 1, wherein the flow channel splits into a plurality of flow channel portions proximate to the light source. 13. A dispensing assembly for use in a refrigerator appliance, the dispensing assembly comprising: a dispenser recess; anda dispenser comprisinga liquid supply positioned proximate to the dispenser recess;a nozzle in fluid communication with the liquid supply and configured to promote a substantially laminar flow of a liquid from the liquid supply to the dispenser recess, the nozzle comprising a first end configured to receive a liquid from the liquid supply;a second end configured to dispense the liquid;a circumferential wall extending from the first end to the second end;a light source having at least a portion positioned within the circumferential wall; anda cone positioned upstream of the light source within the circumferential wall, the cone and the circumferential wall together defining an annulus for the flow through of the liquid from the first end towards the second end; andplurality of contacts positioned along an outer surface of the nozzle and in electrical communication with the light source, the contacts configured to provide the light source with electrical power. 14. A dispensing assembly as in claim 13, wherein the nozzle defines an axial direction, and wherein the cone has a longitudinal axis that is substantially parallel to the axial direction. 15. A dispensing assembly as in claim 13, wherein the flow channel defines a straight section, and wherein the straight section defines a length of at least about 0.01 meters, such that a liquid traveling therethrough has a Reynolds number in the range of about 2500 to about 700. 16. A dispensing assembly as in claim 13, wherein the nozzle defines an axial direction and further comprises a tip positioned at the second end, and wherein the tip comprises a plurality of ribs extending along the axial direction and configured to promote a laminar flow of liquid. 17. A dispensing assembly as in claim 13, wherein the nozzle further comprises an attachment portion positioned at the first end, the attachment portion defining a seal for connection with the liquid supply. 18. A dispensing assembly as in claim 13, wherein the nozzle is releasably connected to the liquid supply.
