Abstract
A layered dimmer formed of different layers. The front layer may be a scattering layer, and the back layer may be a reflective layer. The light beam is scattered prior to reflecting, to avoid reflection back to form hotspots.
Claims18
A dimmer device, comprising:
- a controller for the dimmer device which controls an operation of the dimmer device including an amount of output of the dimmer device;
- a light source, controlled by said controller, said light source being variable in amount of light output based on an output of the controller;
- a movable dimmer system, in a path of an output of said light source, having a first position in the path in which the dimmer does not produce a dimming effect on light output from the light source, and a second position in which the dimmer does produce the dimming effect on light output from the light source,
- said controller operating to first reduce an output of the light source at a time when dimming is desired, second, after reducing the output of the light source, to move said dimmer from said first position in the path to said second position to create said dimming effect, and then after moving said dimmer system to create said dimming effect, to increase the output of the light source.

A method of controlling a method, comprising:
- controlling a power applied to a light source in order to carry an output of the light source;
- also controlling a movement of a movable dimmer system, in a path of an output of said light source, between positions including a first position in the path in which the dimmer does not produce a dimming effect on light output from the light source, and a second position in which the dimmer does produce the dimming effect on light output from the light source,
- carrying out a dimming operation, by operating to first reduce an output of the light source at a time when dimming is desired, second, after reducing the output of the light source, to move said dimmer from said first position in the path to said second position to create said dimming effect, and then after moving said dimmer system to create said dimming effect, to increase the output of the light source.
A dimmer device, comprising:
- a substrate, having first and second oppositely facing surfaces;
- at least a first portion of said second substrate having a dimmer function, which dims light which passes therethrough, and a second portion of said second substrate not carrying out said dimmer function,
- said first portion formed of a patterned layer formed of a plurality of dot areas in a semi-stochastic intensity pattern where a probability is set for each dot area of dimming in said first portion, according to an amount of dimming such that a probability of a dot area being a dimming area is set to the amount of the amount of dimming, and said dot area in said amount of dimming is defined according to said probability.
