  • Patent number: 11630367
    Abstract: Controllers and control methods apply a drive voltage to bus bars of a thin film optically switchable device. The applied drive voltage is provided at a level that drives a transition over the entire surface of the optically switchable device but does not damage or degrade the device. This applied voltage produces an effective voltage at all locations on the face of the device that is within a bracketed range. The upper bound of this range is associated with a voltage safely below the level at which the device may experience damage or degradation impacting its performance in the short term or the long term. At the lower boundary of this range is an effective voltage at which the transition between optical states of the device occurs relatively rapidly. The level of voltage applied between the bus bars is significantly greater than the maximum value of the effective voltage within the bracketed range.

  • Patent number: 11630384
    Abstract: A light source module includes a light source, a wavelength conversion unit, a diffuser, and a reflector. The light source is configured to emit excitation light. The wavelength conversion unit is configured to reflect the excitation light. The diffuser has a first side and a second side opposite to each other, and is configured to allow the excitation light reflected by the wavelength conversion unit to enter the diffuser from the first side and reach the second side. The reflector is configured to reflect the excitation light entering the diffuser, so that the excitation light propagates from the second side to the first side and leaves the diffuser.

  • Patent number: 11630394
    Abstract: Disclosed is a method for lithographically producing a target structure on a non-planar initial structure by exposing a photoresist by means of a lithography beam. In the inventive method, the topography of a surface of the non-planar initial structure is detected. A test parameter for the lithography beam is used and an interaction of the lithography beam with the initial structure and the resultant change in the lithography beam and/or the target structure to be produced are determined. A correction parameter for the lithography beam is determined such that the change in the lithography beam and/or the target structure to be produced that is caused by the interaction of the lithography beam with the initial structure is reduced. The desired target structure on the initial structure is produced by exposing the photoresist by means of the lithography beam using the correction parameter.
