A light reflecting apparatus comprising: an umbrella operably attached about a central mounting hub to hold a support for a photographic light source, the umbrella having expanding joints so that the umbrella is adapted to open into a light reflecting configuration about the light source; a spacer tube adjacent to the central mounting hub; a locking hub operably connected to the umbrella expanding joints through toggle joints and spokes connected to the locking hub, so that displacement of the locking hub toward the spacer tube to contact the spacer tube opens the umbrella into the light reflecting configuration and the locking hub is positioned in front of the plane of the umbrella expanding joints so that the resilient forces in the umbrella are transmitted to the locking hub through the operable connection of the umbrella expanding joints to the locking hub through the spokes and the toggle joints to force the locking hub away from the spacer tube to collapse the umbrella, wherein the locking hub is secured to the spacer tube by actuating a multi-lobe cam within the locking hub so that one or more ball bearings engage and index with index holes on the spacer tube, wherein the locking hub is disengaged from the spacer tube by actuating the multi-lobe cam within the locking hub so that one or more ball bearings disengage from index holes on the spacer tube, wherein said apparatus further comprises an alignment tube connected to the locking hub, the alignment tube being adapted to facilitate engagement between the locking hub and the spacer tube wherein said apparatus further includes the support for a photographic light source, said support being movable through the central mounting hub so that the support is adapted to adjust the position of a photographic light source secured to the support within the light reflecting configuration of the umbrella. an umbrella operably attached about a central mounting hub to hold a support for a photographic light source, the umbrella having expanding joints so that the umbrella is adapted to open into a light reflecting configuration about the light source; a spacer tube adjacent to the central mounting hub; a locking hub operably connected to the umbrella expanding joints through toggle joints and spokes connected to the locking hub, so that displacement of the locking hub toward the spacer tube to contact the spacer tube opens the umbrella into the light reflecting configuration and the locking hub is positioned in front of the plane of the umbrella expanding joints so that the resilient forces in the umbrella are transmitted to the locking hub through the operable connection of the umbrella expanding joints to the locking hub through the spokes and the toggle joints to force the locking hub away from the spacer tube to collapse the umbrella, wherein the locking hub is secured to the spacer tube by actuating a multi-lobe cam within the locking hub so that one or more ball bearings engage and index with index holes on the spacer tube, wherein the locking hub is disengaged from the spacer tube by actuating the multi-lobe cam within the locking hub so that one or more ball bearings disengage from index holes on the spacer tube, wherein said apparatus further comprises an alignment tube connected to the locking hub, the alignment tube being adapted to facilitate engagement between the locking hub and the spacer tube wherein said apparatus further includes the support for a photographic light source, said support being movable through the central mounting hub so that the support is adapted to adjust the position of a photographic light source secured to the support within the light reflecting configuration of the umbrella.
