Abstract: Apparatus for regulating the temperature of a light emitting diode (LED). The apparatus includes a heat sink, an LED mount, and an LED mounted on the LED mount. The LED mount is configured to change shape in response to a change in temperature. The change in shape alters the position of the LED relative to the heat sink, for adjusting heat transfer between the LED and the heat sink. The LED mount may include a laminated portion such as a bi-metallic strip.

Abstract: A method of characterising an LED, as well as an integrated circuit using this method, based on a so-called characteristic resistance, in which the LED is operated at a first, relatively low, operating current and then at a second, relatively high, operating current. From the ratio between the difference between the forward voltages at these two operating currents, and the difference between the operating current, the characteristic resistance is determined. The characteristic resistance is measured at two or more moments during the operational lifetime of the device, and a prediction or estimate is made in relation to the total operational lifetime of the devices, from the evolution or change of the characteristic resistance.

Abstract: A display device comprises a substrate which carries an array of pixels. Each pixel comprises an array of apertures in the substrate, each aperture of the array having a maximum opening dimension less than the wavelength of the light to be transmitted through the aperture. The effective dielectric constant of the aperture and/or the dielectric constant of the substrate is varied, thereby to vary the light transmission characteristics of the pixel between transmission of at least one frequency in the visible spectrum and transmission of substantially no frequency in the visible spectrum.
