A light guide mirror assembly, comprising:
- at least two thin prisms designated as a basic unit, superimposed in a first direction and arranged with predetermined spacing, inclined angle, and position, each of the thin prisms having a bottom surface formed with a plurality of triangular microstructures extending in parallel following predetermined routes and directions, a light incident surface opposite to the bottom surface and a side face, wherein each of the triangular microstructures comprises a vertical face substantially perpendicular to the bottom surface and an inclined face at an acute angle smaller than 90° with respect to the bottom surface, and wherein the at least two thin prisms are designated as a basic unit and the light incident surfaces are oriented towards the same side with respect to the first direction and arranged with predetermined spacing, inclined angle, and position;
- the light guide mirror assembly comprising one or more basic units arranged with predetermined spacing, inclined angle and position, and including but not limited in the staggered relation, in variable quantities at different layers;
- wherein, at least one piece of the thin prism is a focusable thin prism, or, at least one piece of the thin prism is a virtual focus thin prism, or, some of the thin prisms is a no-focus thin prism;
- one or more bases or universal tubes, wherein the at least two thin prisms are resided at a position selected from the group consisting of the one or more bases, accommodation recesses on the one or more bases, the one or more universal tubes, and accommodation recesses in the one or more universal tubes;
- at least one prism rotating module mounted at a position selected from the group consisting of the one or more bases, an accommodation recess on the one or more bases, the one or more universal tubes and an accommodation recess in the one or more universal tubes, and each of the prism rotating module connected to at least one of the thin prisms, so that the thin prisms is adapted for being driven to rotate around the first direction or a direction at the inclined angle;
- wherein the one or more bases are secured by a base fastener or a moveable holder module, so that one or more bases are secured to either have fixed spacing, inclined angle and position, or have variable height, angle, orientation or position, and wherein the moveable holder module includes but not limited to a lifter device, a steering arm, a swinging device, a base rotating module, a telescopic slide member or a flipping/rolling device, an electroactive polymer;
- and
- an Electromechanical control system and interface connected to and adapted to control the prism rotating module and the moveable holder module;
- wherein with or without setting an optical path sensor which is optionally disposed in front of, behind, or onto the thin prisms, and the optical path sensor is an accessory part combined with or without the thin prisms, and the optical path sensor is provided with a plurality of photosensors, with either all of the photosensors being adapted for detecting light beams projected along the same direction, or some of the photosensors being adapted for detecting light beams from several different directions, and the optical path sensor is so connected to the Electromechanical control system and interface as to control output of light beams;
- wherein the mirror assembly is useful in illumination, heat application, photo-thermal power generation, photovoltaic power generation, heat extraction air conditioner, and thermal storage, and adapted for adjusting beam convergence and energy distribution at various sites and devices according to instructions, or for tracking and directing light beams towards a moveable target;
- wherein the light beams output from the light guide mirror assembly is re-concentrated into a directional light beam with a greatly increased application distance, which is useful in cutting large objects, such as rocks, buildings and tunnels, reforming landscape, also by heating sandstone into molten lava and using casting or printing process to perform construction work, directional beam communication, light beam probing and light beam energy transmission.
