According to an embodiment, the first telescoping shaft 101 may be slidably received into the center post 59. Accordingly, the first telescoping shaft 101 may have a smaller outer diameter than that of the center post 59. For example, the first telescoping shaft 101 may be concentrically centered within the center post 59 and slidable along the longitudinal axis of the center post 59. A telescoping shaft lock collar 105 may be provided at the top end of the upper lock collar 55 or on the control panel 85. For example, the control panel 85 may be fixed to and cover the top end of the upper lock collar 55. The telescoping shaft lock collar 105 may receive the first telescoping shaft 101 therethrough. According to an embodiment, the telescoping shaft lock collar 105 may be, for example, a buckle ring. The telescoping shaft lock collar 105 may be configured to have a variable inner diameter. For example, in a first position, the telescoping shaft lock collar 105 may allow the first telescoping shaft 101 to move relative to the center post 59 in both a telescoping and rotational manner and, in a second position, the telescoping shaft lock collar 105 may be tightened around the first telescoping shaft 101 to prevent movement in both a telescoping and rotational manner, by increased friction, of the first telescoping shaft 101 relative to the center post 59. The telescoping shaft lock collar 105 may be provided with a latch 107 in order to move the telescoping shaft lock collar 105 between the first position and the second position. It is foreseen that other devices may be utilized to fix the first telescoping shaft 101 in a position relative to the center post 59 such as, for example, a detent, a shaft inserted through the first telescoping shaft 101 and the center post 59, and other means as known to one of ordinary skill in the art.
According to an embodiment, the second telescoping shaft 103 may optionally be provided. The second telescoping shaft 103 may have a smaller outer diameter than that of the telescoping shaft 101. For example, the second telescoping shaft 103 may be concentrically centered within the first telescoping shaft 103 and slidable along the longitudinal axis of the first telescoping shaft 103. Similar to the above, an additional telescoping shaft lock collar 105 may be provided at the top end of the first telescoping shaft 101. The additional telescoping shaft lock collar 105 may allow the second telescoping shaft 103 to move relative to the first telescoping shaft 101 and in a second position, the telescoping shaft lock collar 105 may be tightened around the second telescoping shaft 103 to prevent movement, by increased friction, of the second telescoping shaft 103 relative to the first telescoping shaft 101. As explained above, it is foreseen that other devices may be utilized to fix the second telescoping shaft 103 in a position relative to the first telescoping shaft 101. According to other embodiments, it is foreseen that any number of telescoping shafts may be similarly incorporated into the telescoping section 21 or, additionally, into the stand section 11 and/or light assembly section 31 of the light stand 1. For example, the light stand with the telescoping shafts extended may be considered a second use-position.
As described above, the inner receiving area of the center post 59, the outer surface and inner receiving area of the first telescoping shaft 101, and the outer surface of the second telescoping shaft 103 may be substantially circular so as to allow relative rotational movement thereof, when desired. However, according to other embodiments, the mating surfaces may be non-circular so as prevent relative rotational movement. For example, if relative rotational movement between the center post 59 and first telescoping shaft 101 is not desired, the inner receiving area of the center post 59 and the mating outer surface of the first telescoping shaft 101 may be square, or hexagonal, or another non-circular shape. Similarly, if relative rotational movement between the first telescoping shaft 101 and the second telescoping shaft 103 is not desired, the inner receiving area of the first telescoping shaft 101 and the mating outer surface of the second telescoping shaft 103 may be square, or hexagonal, or another non-circular shape. It is foreseen that only one or both or none of the center post 59/first telescoping shaft 101 or first telescoping shaft 101/second telescoping shaft 103 may allow rotational movement therebetween about the longitudinal axis A of the light stand 1. For example, the rotational movement of the telescoping shafts may be considered another use-position.

The light panel receiver 153 may include a corresponding latch receiver 199 at an upper end of alignment member 165, as shown at
According to an aspect of an embodiment, the tilting of the light panel holder 153 may be fixed by the center lock member 177, as explained above, independent of the latching of the light panel 33 in the light panel holder 153. For example, the light panel holder 153 may tilt while the light panel 33 is latched in the light panel holder 153. Alternatively, the light panel holder 153 may be fixed by the center lock member 177 while a user may unlatch and remove the light panel 33 from the light panel holder 153.
Thus, a light stand 1 is described that is adjustable on multiple axes. For example, the height and the rotation of the light assembly section 31 may be adjusted with the telescoping section 121, as described above. Further, a tilting angle of the entire light assembly section 31 may be adjusted. Still further, a tilting angle of each light panel 33 may be adjusted independent from the tilting angle of the entire light assembly section 31. Accordingly, the light stand may be configured to be a variety of different use-positions and various combinations thereof.
