Abstract: A cordless motorized roller shade includes a motorized operation device, a shading device mounted on the motorized operation device and hanging down, and a combination module detachably mounted between the motorized operation device and the shading device. Thus, the roll cloth member of the motorized operation device is pressed by the holding units of the shading device so that the roll cloth member is kept at a straight state smoothly when hanging down. In addition, when the roll cloth member is moved upward, the rotary return wheel module of the motorized operation device aids the upward movement of the roll cloth member to reduce consumption of the electric power of the drive motor of the motorized operation device during operation so that the roll cloth member is folded upward in an energy-saving manner.

Abstract: A roller shade includes a frame unit (1), a micro-adjustment device (2) connected with the frame unit, and a shading unit (3) connected with the micro-adjustment device. The micro-adjustment device includes a drive shaft (21) mounted on the frame unit. The shading unit includes a first shade cloth (31) secured to a rear portion the drive shaft, a second shade cloth (32) secured to a front portion of the drive shaft, and a plurality of separation slats (33) mounted between the first shade cloth and the second shade cloth. When the shading unit is fully expanded, the inclined angle of each of the separation slats is adjusted by operation of the micro-adjustment device so as to regulate the lightness of the sunshine entering the house and to adjust the shading effect of the shading unit.

Abstract: An energy saving apparatus for an electric roller shutter contains a curtain unit, a fixing unit, a signal receiver, and a controller. The curtain unit includes a driving shaft having a chamber and a rotary connecting portion, and the curtain unit also includes a driver and a curtain. The fixing unit is configured to fix the curtain unit and includes a mounting rack, a first seat, a second seat, and a rolling assembly which reduces power consumption of the driver and facilitates an upward rolling of the curtain, when the curtain rolls. The signal receiver is electrically connected with the driver and includes a casing, a coupling portion, a power supply module, and a receiving module. The controller is configured to send a signal to the receiving module in the casing of the signal receiver, such that the driver of the curtain unit is controlled by the controller to operate.

Abstract: A roller shade includes a frame unit (1), a guiding unit (2) and a light regulating shading member (3). The light regulating shading member presents a two-layer state and has a plurality of light shading sections (31) and a plurality of light permeating sections (32). Each of the light permeating sections is provided with a plurality of through holes (321). When the light permeating sections at one layer of the light regulating shading member align with the light permeating sections at the other layer of the light regulating shading member, ambient sunlight passes through the through holes of each of the light permeating sections. When the light shading sections align with the light permeating sections, each of the light shading sections covers the through holes of each of the light permeating sections to interrupt the sunlight.
