A transparent chromogenic assembly in which color changes are selectively effectable over predefined areas comprises a pair of facing transparent substrates ( ) each covered with a conductive layer divided into individual energizeable areas each provided with a set of busbars ( ). A passive layer may be superimposed over one of the substrates, its color being chosen so that the color and the transmissivity of the passive layer accommodates the range of color change and transmissivity of the electrochromic layer to maintain the transmitted color of the panel in a warm or neutral shade. Various other chromogenic windows, devices and systems are also disclosed.

Chromogenic glazing

A user-controlled skylight window or the like in which the user can control the light transmitted through the skylight. A chromogenic filter is under automatic control of a control circuit. A user interface permits the user to set the control circuit for desired lighting. A mechanical shutter is likewise controlled to open or close the skylight under control of the user interface. A lamp within the skylight provides nighttime lighting under user control. The diffuseness of light transmitted through the skylight is improved by modifying the diffuseness of various components of the skylight including the filter. Uses of the filter in a variety of systems and with a variety of controls are disclosed.
