Abstract
A curing light includes a light source having an array of light emitting diodes (LEDs), the LEDs being held in a holder so that the emitters of the LEDs define a spherical surface having a known radius. Light is transmitted by the LED array to a receiver formed as a bundle of optical fibers. A receiving end of the receiver is positioned at distance from the array so that substantially all light emitted by the diodes is captured by the receiver. The bundle is drawn is such manner that it has a diameter of between 14 and 25 millimeters at a light receiving end, and a diameter of between 3 and 13 millimeters at a light transmitting end. A collimating lens is optionally interposed between the light source and the receiver.
