[0035] It is generally contemplated that the illumination system 64 includes a plurality of lighting assemblies 10 positioned within the housing 62 to form a lighting array 80. Stated differently, the lighting array 80 is comprised of the plurality of lighting assemblies 10. The lighting array 80 may be independently powered and operated relative to the air handler units 50, and each light assembly 10 of the lighting array 80 may be independently powered relative to an adjacent light assembly 10.

[0038] An actuator ring 102 is disposed around the central shaft 100 proximate to the upper mount 12 and the printed circuit board 28. The actuator ring 102 is configured to selectively engage with at least one of the sensors 30 on the printed circuit board 28, as described in more detail herein. The first actuation device (e.g., the pan motor 22) is illustrated as including a first drive gear 104 that extends through an aperture 106 defined in the printed circuit board 28. The first drive gear 104 and the pan gear 14 form a first gearing assembly 109 (
[0039] The pan motor 22 and the tilt motor 24 are disposed within the lower mount 20. The lower mount 20 includes a first arm 118 and a second arm 120. The first and second arms 118, 120 are configured to couple the light module 32 to the lower mount 20. Each of the arms 118, 120 includes a retention aperture 122 in which an attachment feature 124 of the light module 32 is disposed. It is generally contemplated that the pan motor 22 is disposed within the first arm 118, and the tilt motor 24 is disposed within the second arm 120. The operation of the pan and tilt motors 22, 24 along with the pan and tilt gears 14, 34, respectively, are described in more detail herein.
[0040] With reference now to
[0041] The upper mount 12 is rotatably coupled to the lower mount 20 via the first drive gear 104 and the pan motor 22. The pan gear 14 engages the first drive gear 104, which extends from the pan motor 22 within the lower mount 20. It is generally contemplated that the upper mount 12 is fixed relative to the lower mount 20, such that the engagement between the first drive gear 104 and the pan gear 14 results in the circumferential rotation of the lower mount 20 relative to the upper mount 12. As mentioned above, the first drive gear 104 is aligned with and extends through the aperture 106 defined by the printed circuit board 28 and selectively engages, or interlocks with, the pan gear 14 of the upper mount 12 to rotate the lower mount 20. Stated differently, the pan motor 22 may be in communication with the pan gear 14 through the aperture 106. The printed circuit board 28 includes the plurality of sensors 30, and the plurality of indicator flanges 16 centrally and circumferentially extend from the upper mount 12 toward the plurality of sensors 30. The plurality of indicator flanges 16 selectively engage with the sensors 30 disposed along the printed circuit board 28. The indicator flanges 16 selectively pass through the sensors 30 to indicate a position of the lower mount 20 relative to the upper mount 12.

[0043] As illustrated in
[0044] With further reference to
[0045] The proximity tab 164 passes over the proximity sensor 166 to communicate with the controller 36 the position of the lower mount 20 relative to the upper mount 12 as the lower mount 20 rotates. Stated differently, the proximity tab 164 and the proximity sensor 166 cooperate to inform the controller 36 as to the rotational position of the lower mount 20. By way of example, and not limitation, the lower mount 20 may be rotated approximately 540 degrees relative to the upper mount 12, and the proximity tab 164 and the proximity sensor 166 cooperate to inform the controller 36 of the rotational position of the lower mount 20.
[0046] It is generally contemplated that the lower mount 20 is configured to rotate approximately 540 degrees relative to the upper mount 12. The home indicator flange 150 may pass within the home sensor 152 two times during a single rotation. The proximity tab 164 remains over the proximity sensor 166 during the first 270 degrees of rotation of the lower mount 20 relative to the upper mount 12. The first mechanical stop 142 engages the engagement feature 162 after the initial 270 degrees of rotation, which displaces the proximity tab 164 from the proximity sensor 166. The displacement of the proximity tab 164 indicates to the controller 36 that the lower mount 20 is displaced from a home position relative to the upper mount 12. Stated differently, the home indicator flange 150 may be disposed in either of the first or second home sensors 154, 156 while being displaced from the home position when the proximity tab 164 is displaced from the proximity sensor 166.
[0047] Referring still to
[0048] With reference to
[0049] The tilt motor 24 is configured to tilt or otherwise angle the light module 32 relative to the lower mount 20. The tilt motor 24 is configured to face or be aligned with a second direction opposite the first direction (e.g., away from the upper mount 12), such that a shaft of the tilt motor 24 extends along the second direction. The tilt motor 24 tilts the light module 32 between a first position 194 (
[0050] The Hall sensor 112 is configured to detect a magnetic field of the magnet 110 to detect the position of the light module 32 relative to the lower mount 20 and the printed circuit board 28. The Hall sensor 112 is communicatively coupled with the controller 36 to indicate a position of the light module 32 relative to the lower mount 20. The magnet 110 coupled to the tilt motor 24 is configured with a dual hemispherical polarity, such that the Hall sensor 112 may detect the position of the magnet 110 based on the pole position. The magnet 110 rotates about a shaft 186 coupled to the tilt motor 24 as the tilt motor 24 tilts or otherwise actuates the light module 32 relative to the lower mount 20. The rotation of the magnet 110 indicates to the Hall sensor 112 the position of the light module 32 relative to the lower mount 20.
[0051] With further reference to
[0052] With reference again to
[0053] It is generally contemplated that the controller 36 may activate a reverse operation to rotate the lower mount 20 back to a start position once the sensors 30 on the printed circuit board 28 detect a complete rotation of the lower mount 20. The controller 36 operates the rotational function of the lower mount 20 via activation of the pan motor 22 and also operates the tilt function of the light module 32 via activation of the tilt motor 24. It is also contemplated that the controller 36 is configured to adjust and activate a brightness of the light module 32 during operation. The controller 36 may be selectively activated via a user interacting with a user interface 200 or other user control. By way of example, not limitation, the user interface 200 may be a wireless computing device connected to the controller 36 via a wireless network 202.
[0054] Additionally or alternatively, the network 202 and/or the user interface 200 may include wired connections. It is also contemplated that the user interface 200 may be communicatively coupled with the controller 36 in each of the lighting assemblies 10 of the illumination system 64, such that the user interface 200 may activate a single light assembly 10 within the illumination system 64 and/or activate multiple lighting assemblies 10. The user interface 200 may also be configured with indicia associated with various functions of the lighting assembly 10 including, but not limited to, rotation and/or tilting of the lower mount 20 and light module 32, respectively.
[0055] Referring now to
[0056] Referring now to
[0057] In general, the arrangement of the actuation devices (e.g., the first and second motors 22, 24) and/or the printed circuit board 28 may provide for a reduced packaging size, and further may allow for a reduced cost. The modularity of the lighting assembly 10 may further allow for ease of replacement for individual lighting assemblies of the lighting array 80. Further, the non-rotational relationship of the pan gear 14 with the upper mount 12 and the tilt gear 34 with the light module 32 may maximize the overall useful life of the light assembly 10. The 540 degrees of rotation also provides maximum lighting options during surgical procedures and/or other situations in which the rotation of the lighting assembly 10 may be advantageous. In addition, the inclusion of the plurality of sensors 30 within the lighting assembly 10 advantageously provides the controller 36 with position verification of the lower mount 20 and the light module 32, respectively.
[0058] The indicator flanges 16 cooperate with the plurality of sensors 30 to detect the rotation of the lower mount 20 relative to the upper mount 12. The controller 36 is in constant communication with the printed circuit board 28 regarding the position of the lower mount 20 relative to the upper mount 12. By way of example, not limitation, the controller 36 may store the rotational information detected by the plurality of sensors 30 within the detection storage system 158 to minimize disruption as a result of any potential power outages. Stated differently, the controller 36 may detect the incremental position of the lower mount 20 to detect whether the lower mount 20 has moved relative to the home position. If the lower mount 20 has moved, then the controller 36 may reposition the lower mount 20 to the home position, such that the home indicator flange 150 is detected by the home sensor 152. Additionally or alternatively, the controller 36 may detect whether the pan and/or tilt motors 32, 34 are executing the instructions from the controller 36 properly, such that significant deviations from the instructions may result in the controller 36 deactivating the respective lighting assembly 10.
