摘要 |
A light-emitting diode (LED) print head has a linear array of LEDs and device drivers for delivering current to each LED individually. An imaging lens system to create a real image of the LED array is provided in the form of a plurality of gradient index lenses and the LEDs each have emission cones closely matched to the numerical aperture of the gradient index imaging lenses.
