High performance LED and OLED mirror-type lighting for illuminated mirrors

Lumidesign designs and manufactures lighted mirrors, mirror TV's and other architectural metal andglass-based lighting products. Their most important product series incorporates LED (Light Emitting Diode)lighting into vanity mirrors and vanity mirror cabinets, representing 16 standard products line for Lumidesign.These products currently use LED lighting in which a specific portion of the glass mirror sheet is modified tobecome non-reflective and is delegated to the light source. LED lighting is placed behind these non-reflectiveportions of the glass mirror sheet to provide illumination emanating from the front of the mirror.Lumidesign wishes to differentiate their products from the competition in this market by developing atechnology to have the mirror lighting invisibly located behind the mirrored glass surface when the lighting isnot required. Then, when the lighting is turned on, the backlit portions of the mirrored surface are to allow forlight to be efficiently emitted. Lumidesign currently has access to partially-mirrored glass that can achieve thiseffect, however the mirrored finish covering the LED lighting causes substantial light loss and is therefore notpractical.At McMaster University we have expertise in optical design, optical computer modelling and prototypedevelopment. Specifically, optical coatings and optical films that simultaneously provide a mirror finish andalso act as efficient window materials for LED and OLED (Organic Light Emitting Diode) light to passthrough can be developed. During this project we will develop a solution for Lumidesign that demonstrateshigh efficiency mirrored light sources as well as a set of measurements demonstrating the superior energyefficiency of the result.
