摘要： A method and apparatus for cooling an electronic component, such as an optoelectronic device, is described. The method involves arranging a porous material to be able to receive heat from the electronic component and removing heat from the porous material as a result of vaporisation of a coolant delivered to the porous material. In this manner, a temperature gradient is generated that causes heat to flow from the electronic device to the porous material, resulting in the electronic device being cooled.

摘要： A modifying structure lens (1) is formed over a LED light source (2) so as to act to focus the light into the appropriate configuration (ray direction) and simultaneously extract heat from the upper and side surface of the LED chip (2). The LED light source (2) is mounted to a rear heat sink body (4). The lens (1) comprises a primary region (5) immediately adjacent the LED source (2) (and within which the LED source (2) is embedded). The primary region (5) includes a diamond compound particulate material distributed throughout a flexible gel matrix, as will be described in detail hereafter. An overlaying layer (6) of a light transparent material is not impregnated with the diamond compound material.

摘要： The invention provides an arrangement having first and second light sources and an imaging device. The light sources have different wavelengths. The first light source is positioned such that the imaging device is able to take images of an object under test that is backlit by said first source of light: the second light source is positioned such that the imaging device is able to take images of the object based on light reflected from the surface of said object. In use, the imaging device simultaneously generates a first image resulting from light provided by said first light source and a second image resulting from light provided by said second light source.

摘要： A cooled light emitting apparatus (1) comprises a light source including a close packed array (2) of light emitting diode devices (high intensity LEDs) and a cooling system for cooling the light source. The cooling system comprises a thermoelectric cooling device in the form of a Peltier device (4) connected via a heat spreader (3) to the light source and a heat exchange system (5, 6) for removing heat from the Peltier device (4). The heat exchange system (5, 6) uses liquid coolant (or refrigerant) to cool the Peltier device (4). By extracting heat from the LED array (2) at a rate greater than 5W cm -2 it is possible to maintain the LED array at a temperature of less than -10 degrees Celsius, and thus emit light having an optical power density of greater than 1Wcm -2 .

摘要： A method and apparatus suitable for driving one or more LEDs (20) from an AC mains power supply (2b) is described. An input circuit (10) receives AC mains power (2b) having a sinusoidal waveform and converts, for example by means of a suitable driver (14), said AC mains power into a pulsed LED drive current (2d) having a cyclically varying current, for example in the form of a modified sinusoidal waveform. There may be provided a circuit (12) for monitoring and detecting the instantaneous level of a rectified waveform (2c), thus facilitating regulation of the drive current (2d) by the driver (14).

摘要： An LED array and a method for controlling such an array is described. The array includes one or more LED-optical sensor pairs in which the optical sensor measures the light output of the associated LED. In some forms of the invention, the optical sensors are provided with filters to attenuate light at a wavelength different to that of the LED associated with that optical sensor. In some forms of the invention, the LED-optical sensor pairs are at least partially shielded from extraneous light. In one form of the invention a plurality of sets of LEDs is provided, each set outputting light having a different frequency and each set being controllable to provide a desired light output.
