A daylight transmission system that can be used in buildings, the system including: dual-axis implementation device, CPU-controller, light position sensor and optical components that include moving and fixed optical components; with the moving optical components including optical light collector and the fixed optical components including first receiver and consecutive receivers. The invented system transmits sunlight in a form of parallel light after it is concentrated and therefore does not rely on expensive medium such as optic fibers, with the entire process being efficient in light transmission and economically viable. With the help of a tracking device, sunlight of any incident angle will be reflected in a fixed direction and to a fixed point where the light is reflected further on to the desired destination inside of a building. The invented system can be installed directly onto the external wall of any building, and be applied within a wide range of buildings.

A heliostat contained within a mechanical enclosure is described that optimizes the heliostat for domestic applications by emphasizing features of durability, protection from outside weather, low cost of manufacture, self-powering, light-weight, and aesthetics.

A system and mechanism that redirects sunlight towards a target destination. The system has an array of double prismatic discs that are controlled by a control module that includes a light detecting module. The system is modular and will work for any elevation and azimuth of direct sunlight. The system will further provide one or more remote functionalities. The system can be used to provide collimated solar side or top illumination for indoor spaces, directly or in combination with reflectors. The system may be combined with a hybrid solar lighting (HSL) panel to provide indoor illumination through optical fiber cables. The system may be combined with a concentrated photovoltaic (CPV) panel or with a concentrated solar thermal (CST) panel to produce electricity or heat respectively. The system replaces the solar tracker typically used in these applications, which enables the assembly to be integrated in buildings and vehicles without altering their aesthetics.

A system that illuminates water in a water display in broad daylight is described. The system may include a color filter that directs a desired color or range of colors onto the water. The source of light may be the sun or an artificial light source. Where the light source is the sun, a heliostat may be included to track the sun and reflect sunlight to the color filter. Other reflecting mirrors may be included to provide a line of sight between the light source and water display being illuminated.

A system and method for converting the sun's electromagnetic radiation to work, where the system collects the radiation with at least first one lens or mirror. Splitting means split the radiation spectrum, preferably using prism, set of prisms, diffraction grating, or set of beam splitters. Second one lens or mirror is configured to collect the radiation separately for each wavelength range. At least one fiber optic cable is configured to transfer the radiation to electromagnetically or electrically operated appliance, device or machine.

A solar light system may include two stages of optical concentration with intermediate removal of infrared radiation between the optical concentration stages. A second stage of optical concentration may prepare multiple concentrating beams of processed solar radiation with visible light with each such concentrating beam directed to a different corresponding light conduit for transmission to an interior space for interior lighting. System modularization may provide flexibility to accommodate a variety of interior lighting applications.

Embodiments described herein may relate to a system comprising a plurality of optical elements, comprising at least a first optical element and one or more secondary optical elements, a heliostat comprising the first optical element, where the heliostat is operable to move the first optical element to continuously reflect light from a non-stationary light source in a beam towards a first of the secondary optical elements, and where the secondary optical elements are arranged to re-direct the reflected beam of light towards an illumination target. The system further includes a controller configured to receive position data indicative of the position of the non-stationary light source over time, and in response to the position data, control at least the heliostat to continuously direct the beam of light towards the first of the secondary optical elements, such that the beam of light is continuously re-directed towards the illumination target.

A heliostat contained within a mechanical enclosure is described that optimizes the heliostat for domestic applications by emphasizing features of durability, protection from outside weather, low cost of manufacture, self-powering, light-weight, and aesthetics.

A heliostat optimized to be positioned near a skylight or other aperture is disclosed. The heliostat comprises a plurality of reflective elements arranged in a substantially planar array, each element being mounted so as to be rotatable about a longitudinal axis of rotation. A first motor rotates the array about an axis substantially perpendicular to the plane of the array; and a second motor rotates the reflective elements about their respective axes of rotation. A processor provides control signals to operate the first motor as required to orient the array such that the respective axes of rotation of the reflective elements are substantially perpendicular to an azimuth to the sun and to operate the second motor as required to rotate the reflective elements about their respective axes of rotation to position the reflective element to reflect the sun's light to a target area.
