Publication number: 20120281408Abstract: A high-intensity light source is formed by a micro array of a semiconductor light source such as a LEDs, laser diodes, or VCSEL placed densely on a liquid or gas cooled thermally conductive substrate. The semiconductor devices are typically attached by a joining process to electrically conductive patterns on the substrate, and driven by a microprocessor controlled power supply. An optic element is placed over the micro array to achieve improved directionality, intensity, and/or spectral purity of the output beam. The light module may be used for such processes as, for example, fluorescence, inspection and measurement, photopolymerzation, ionization, sterilization, debris removal, and other photochemical processes.Type: ApplicationFiled: May 8, 2012Publication date: November 8, 2012Applicant: PHOSEON TECHNOLOGY, INC.Inventors: Mark D.

Patent number: 7524085Abstract: The light array of this invention includes a number of columns and rows of LED's connected in a series/parallel combination. The series parallel combinations effectively optimize the impedance, accommodate failure rate, facilitate light mixing, provide a means of imbedding redundancy, and common cathodes or anodes. This arrangement provides a superior light source for consumer, industrial and specialty markets in respect to mean time between failure, process control, radiant intensity, wavelength mixing, power requirements and other characteristics of the light source. Each column includes a number of rows of plural LED's. The LED's in each row are wired in series and each column is wired in parallel so that if one LED fails only the LED's connected in series with the failed LED will also fail. There is redundancy in the circuit as well as the arrays so that if there are failures different current carrying elements or different series LEDS will automatically by powered on.Type: GrantFiled: October 29, 2004Date of Patent: April 28, 2009Assignee: Phoseon Technology, Inc.Inventors: Jon R.
