Abstract: The present invention relates to the sunshade driving device comprising that: a returning function of a manual driving module (410) is actuated by a ball chain or a rotating string; a rotating shaft (491) is attachable/detachable to the power drive unit or the rotating shaft stopping unit separated from a manual driving module; at least one pick-up member (452, 453) to directly drive the sunshade rotating shaft or driving the rotating shaft (491) by the manual drive module (410); a wheel driving member (417) having a manual pulley (417a) or a manual driving wheel (412b) being fitted the ball chain or rotating string; wherein the wheel drive member (417) will be engaged to the manual rotating wheel (412b) and the manual pulley (417a) for rotating together in one direction, and the wheel driving member (417) will disengaged the manual rotating wheel (412b) and the manual pulley (417a) for independently rotating each other in opposite direction activated by a bi-directional driving clutch (417b).

Abstract: The present invention relates to the sunshade driving device comprising that: a returning function of a manually driving module (410) is actuated by a ball chain or a rotating string; a rotating shaft (421) is attachable/detachable to the power drive means or the rotating shaft stopping means separated from a manual driving module; at least one pick-up member (452, 452?) to directly drive the sunshade rotating shaft or driving the rotating shaft (421) by the manual drive module (410); a wheel driving member (415?) having a manual pulley (415a) or a manual driving wheel (412b) being fitted the ball chain or rotating string; wherein the wheel drive member (415?) will be engaged to the manual rotating wheel (412b) and the manual pulley (415a) for rotating together in one direction, and the wheel driving member (415?) will disengaged the manual rotating wheel (412b) and the manual pulley (415a) for independently rotating each other in opposite direction activated by a bi-directional driving clutch (415b).

Abstract: A new concept of the light guide device has developed to have multi channels, the present invention comprises: a transparent body through which light can freely pass; channel condensing units disposed at predetermined intervals on the body to form a plurality of one-dimensional arrays; an optical module unit for independently sighting incident light, and re-sighting and focusing light which passes through the one-dimensional arrays formed by the channel condensing units disposed at predetermined intervals in the body; and a fiber channel module for creating independent light passages (fiber channels) which condense light from the left, right, up and down aspects of the optical module unit, at a one-to-one correspondence between the body and the optical module unit. The present device maximizes the efficiency of the solar energy utilization by reducing the guide distance of incident light.
