US 2015/0092259 A1 · Control System For Color Rendering Of Optical Glazings

Abstract

The present disclosure provides for a method of controlling a plurality of independently controllable sections of one or more electrochromic devices belonging to a common interior space to provide lighting having a substantially color neutral or aesthetically pleasing spectrum to the interior space. The method comprises receiving a desired illuminance input indicating an amount of lighting desired in the interior space, and a neutral lighting input indicating a quantifiable amount of the sections of the electrochromic devices to be set to a high transmittance state. One or more sections of the electrochromic devices are selected in accordance with the neutral lighting input. The selected sections of the electrochromic device are set to the high transmittance state. The one or more electrochromic devices collectively transmit an amount of light into the interior space in accordance with the desired illuminance input.

Dependent claims

A method of controlling a plurality of independently controllable sections of one or more electronically tintable devices belonging to a common interior space, the method comprising:

receiving, at a processor, a neutral lighting input indicating a quantifiable amount of the one or more electronically tintable devices to be set at a high transmittance state;
receiving, at the processor, a second input associated with one of a desired heating or lighting condition of the interior space;
selecting, at the processor, a subset of the independently controllable sections in accordance with the neutral lighting input;
and
controlling the one or more electronically tintable devices such that the selected subset of sections are set to a first state for admitting light having a substantially color neutral or aesthetically pleasing spectrum into the interior space, and such that the remaining unselected sections are controlled in accordance with the second input, wherein the overall spectrum of light transmitted through the electronically tintable device has a substantially color neutral or aesthetically pleasing spectrum.

2 more elements

A control device for independently varying the transmittance of one or more portions of at least one electronically tintable device, the control device comprising:

a power source electrically coupled to each of the portions of the at least one electronically tintable device, the power source configured to independently supply power to each of the portions;
and
a processor electrically coupled to the power source, the processor configured to control an amount of current or voltage supplied to each of the portions of the electronically tintable device such that a first portion of the electronically tintable device is set at a first state for blocking at least one of daylight, solar heat, and solar glare, while a second portion of the electronically tintable device is set at a second state for transmitting light having a substantially color neutral or aesthetically pleasing spectrum, wherein the overall spectrum of light transmitted through the electronically tintable device has a substantially color neutral or aesthetically pleasing spectrum.
