InfiniLED, a world-leader in MicroLED and MicroLED array technology headquartered in Ireland, claims its latest MicroLEDs (μLEDs) have set up the highest recorded for a commercially available LED type device, with a light output density of more than 300 W/cm2.
The device can produce up to 1mW of light from a single 20μm pixel at 405nm.
The MicroLED combines the benefits of a laser and a LED to produce ultra-high light output. The MicroLED provides the wavelength flexibility, drive characteristics and simplicity of a LED as well as the power and collimated beam of a laser.
The ability to produce such light intensity and control directly from the chip enables the light to be efficiently used in a range of applications. InfiniLED has achieved this performance using its patented MicroLED structure.
A parabolic reflector is etched into the semiconductor material during the fabrication process. This places an optical component directly at the site of light generation and at the most effective position for control of the light produced.
The MicroLED is currently being used in a range of applications included life sciences, consumer electronics and OEM equipment. The device can be fabricated as a single pixel, large clusters of pixels or as addressable arrays where each pixel is individually switchable. The single pixels can be used to produce high intensity, collimated light over a small area or to produce useable light at ultra-low currents. The single pixels produce light with a few nanoamps of current. To produce larger amounts of light, clusters of tightly packed MicroLEDs are available.
