at least one light source;
at least one photovoltaic component residing at at least one window blind assembly of the plurality of window blind assemblies; and
at least one rechargeable battery electrically coupled to and charged by the at least one photovoltaic component, wherein the at least one rechargeable battery is electrically connected to and capable of powering the at least one light source of each of the plurality of window blind assemblies.
2. The system of claim 1 , wherein each window blind assembly of the plurality of window blind assemblies further includes a microcontroller for controlling the motor.
3. The system of claim 1 , wherein, for each window blind assembly:
the light blocking assembly is capable of assuming a deployed configuration and a retracted configuration;
the light blocking assembly blocks external light from entering the room when in the deployed configuration;
allows external light to enter the room when in the retracted configuration; and
the at least one light source is disposed on the at least one light blocking assembly.
4. A solar window blind system located at a window of a room, the system comprising:
a window blind having a room portion that can face the room and an exterior portion that can face away from the room towards an exterior of the window;
at least one motor operatively connected to the window blind for moving the window blind;
at least one photovoltaic component disposed on the window blind;
a rechargeable battery electrically connected to the at least one photovoltaic component and charged therewith;
at least one light source electrically connected to the rechargeable battery, the at least one light source being disposed on at least one of the room portion to shine light into the room and the exterior portion to shine light into the exterior of the window, the at least one light source capable of being powered by the rechargeable battery when the at least one light source is in use;
a microcontroller operatively connected to the at least one light source, wherein the microcontroller controls at least one of a duration, a color, and an intensity of the at least one light source, and wherein the microcontroller is capable of turning on the at least one light source in response to a triggering event, said event being at least one of motion being detected and a security alarm being set; and
a plurality of rotatable slats, each slat having a concave side and an opposite side, the concave side being adapted to receive sunlight at an incident angle after passing through the window, wherein:
the at least one photovoltaic component is disposed on the window blind on the opposite side of each slat;
at least one light source includes a series of light emitting diodes running along each slat, such that light emitted from the light emitting diodes can be directed in different directions depending on how much the slat on which the series runs along is rotated; and
depending on the incident angle, a concave side of one slat can reflect the sunlight to the at least one photovoltaic component on an opposite side of an adjacent slat or can reflect light back out through the window.
5. A solar window blind system located near a window that separates an interior space of a room and an outdoor space, the system comprising:
a window blind that includes a slat having an interior-facing side that faces the room and an exterior-facing side that faces out the window towards the outdoor space;
a photovoltaic component disposed on the window blind;
a rechargeable battery electrically connected to the photovoltaic component and charged therewith;
at least one motor for moving the window blind, said motor being powered by the battery;
a light source disposed on the exterior-facing side of the slat that is capable of shining light through the window to the exterior space, said light source being powered by the rechargeable battery;
a plurality of rotatable slats, each slat having a concave side and an opposite side, the concave side being adapted to receive sunlight at an incident angle after passing through the window; and
at least one photovoltaic cell disposed on the opposite side of each slat, the rechargeable battery electrically connected to the at least one photovoltaic cell and charged therewith, wherein, depending on the incident angle, the concave side can reflect the sunlight to the at least one photovoltaic component on the opposite side of an adjacent slat or can reflect light back out through the window.
