Abstract

of the Invention Disclosed herein an apparatus for mimicking the light and sky-conditions at the horizon comprises a light assembly (2) provided with at least two angularly disposed horizontal strips (9a and 9b) of light source, a composite lens (5) fixedly placed above the light assembly (2) and configured to selectively reflect and transmit the light incident on it, a reflecting dome (3) centrally and partially disposed over the composite lens (5) and light assembly module (2) and provided with an LED spotlight (12) under it, a mounting bracket (4) adapted to receive the light assembly and the composite lens; and a controller (11) configured to control and monitor one or more predetermined parameters of the light source (9), wherein the characteristic of the composite lens (5) is translated depending on the desired geographical location. A corresponding method for mimicking the light and sky-conditions at the horizon is also disclosed.

Dependent claims

An apparatus for mimicking the light and sky-conditions at the horizon comprises:

a light assembly (2) provided with at least two horizontal strips (9a and 9b) of light sources, wherein each said strip (9) comprises of a plurality of LED lights (9) arranged in series;
a composite lens (5) fixedly placed above the light assembly (2) and configured to selectively reflect and transmit the light incident on it;
a reflecting dome (3) centrally and partially disposed over the composite lens (5) and light assembly (2) and provided with an LED spotlight (12) under it;
a mounting bracket (4) adapted to receive the light assembly and the composite lens;
and
a controller (11) configured to control and monitor one or more predetermined parameters of the light sources (9);
and
wherein said horizontal strips (9a and 9b) are angularly disposed relative to each other in order to enable the light emitted from the horizontal strips (9a and 9b) to strike the composite lens (5) at various angles of incidence with the horizontal for reflecting, transmitting and interfering/diffusing to form a composite light corresponding to lights of a set of desired light and sky-conditions at a specific time of a predetermined geographic location;
and
wherein another set of desired light and sky-conditions at another specific time of another predetermined geographic location is obtained by optimizing the angle between the LEDs (9) of the strips (9a and 9b) and light intensity from the strips (9a and 9b) of the light sources and alternating the relative placements and characteristics of optical layers of the composite lens (5) and a selected combination of the optical layers of the composite lens (5).

A method for mimicking the light and sky-conditions at the horizon comprising:

receiving instructions by a controller for mimicking a desired light and sky-conditions at a specific time of a predetermined geographic location;
emitting lights in a predetermined range of spectral wavelength from a plurality of angularly disposed light sources and from another light source;
striking the emitted lights angularly at various angles of incidence with the horizontal onto a combination of a plurality of optical layers (6,7 and 8) for reflecting and transmitting the lights;
diffusing the reflected and transmitted lights from and through the combination of a plurality of optical layers (6,7 and 8) to form a composite light corresponding to the desired light and sky-conditions at the specific time of the predetermined geographic location followed by visualizing the mimicked desired light and sky-conditions;
and
wherein the method comprises of reflecting and transmitting the lights angularly and selectively from and through the combination of the plurality of optical layers (6,7 and 8) for filtering out the emitted lights to form the composite light as per the instruction for a set of the desired light and sky-conditions at the specific time of the predetermined geographic location;
and
wherein the method comprises of obtaining another set of desired light and sky-conditions at another specific time of another predetermined geographic location by controlling and optimizing the angles of incidences with the horizontal, light intensities, and alternating the relative placements and characteristics of the optical layers (5) and the selected combination of the optical layers (5).
