By introducing a highly geared, self-braking worm drive, the lightshelf may be positioned anywhere form zero to 90 degrees for maximum control of daylight entry. This will allow the lightshelf to be partially closed to block low winter sun angles, but still allow daylight to reach the ceiling. An attached or detachable folding crank provides the operation.
Our base product is operated by a wand or pole and features 3 optional positions for the angle of the lightshelf. The roller shade is chain operated.
A conventional tube motor with reduced speed is housed in a custom airfoil extrusion to drive the lightshelf. Since the roller shade is also driven by conventional tube motor both components may be controlled by the same remote control as well as Smart phone App. Alternatively, systems are available with simple wire-less wall switches.
