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.

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 vaporization 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 cooled light emitting apparatus 1 comprises a light source including a close packed array 2 of light emitting diode device (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 5 W 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 1 Wcm -2 .

摘要： Methods and devices for sensing foreign bodies and the like in products, such as food products (6a, 6b, 6c) , are described. Said products, which are generally light transmissive, are backlit by a source of light (8) and an image of said object is taken (10) . In one form of the invention, the light is polarized both before and after transmission through the said object. In another form of the invention, the products are conveyed by a holder (4) having gaps therein that allows the light from said light source to pass through said holder. In some forms of the invention, the source of light has a power output dependent on the dimensions of said object.

摘要： A method and apparatus for improving the cosmetic appearance of a region of skin (11) affected by Acne Vulgaris, Rosacea or similar skin condition by means of directing light radiation (12) from an illuminating device (1) on to the skin (11). The apparatus (10) comprises a control unit (9) that operates one or more LEDs (7) (light emitting diodes) of the illuminating device (1). Each dose of light radiation (12) lasts for at least 100ms, during which time the skin 11 receives light energy from the LED(s) (7), which causes a photochemical reaction that stimulates the production of free radicals (singlet oxygen) that react with, and at least partially disable or destroy, bacteria that contribute to the symptoms of the skin condition. The light energy directed on to the skin (11) during any given period of 10µs is less than 0.5 Jcm 2, and during any given period of 100ms is less than 5 Jcm-2. Substantially no beneficial photo-thermal reaction occurs within the skin (11). Light having wavelengths around 405nm and/or 585nm is used. The duration of a single dose may be much longer than 100ms and can last up to 10 hours (for overnight treatment).

摘要： A light emitting semiconductor device mounted on a heat sink and having a heat pipe located on its upper surface. The heat pipe comprises a sealed cylindrical member of transparent or translucent material having a wick disposed down the side and along the bottom thereof. The heat is partially filled with a liquid which is placed under a partial vacuum to reduce its boiling point. A bundle of optical fibres may be provided within the heat pipe, with the gaps created between the optical fibres providing an efficient capillary action within the heat pipe for transport of vapour to the cool end of the pipe and for transport of condensed coolant to the hot end of the pipe.
