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.

High efficiency solid-state light source and methods of use and manufacture

The present invention provides an optical array module that includes a plurality of semiconductor devices mounted on a thermal substrate formed with a plurality of openings that function as micro-reflectors, wherein each micro-reflector includes a layer of reflective material to reflect light. Such material preferably is conductive so as to provide electrical connection for its associated semiconductor device.

Micro-reflectors on a substrate for high-density LED array

System and methods are disclosed in connection with a reaction at or below the surface of a work object, in the context of a fluid flow fostering the reaction. In some example embodiments, the reaction is fostered by (1) creating fluid flow of an inerting fluid over a surface during exposure of the surface to a predetermined type of light, (2) creating fluid flow comprising a reactive species that reacts with another species at or below the work surface in a predetermined manner and/or (3) creating a fluid flow comprising a catalytic species that catalyzes a reaction in a predetermined manner, e.g., during exposure of the surface to a predetermined type of light. In some example embodiments, a light source is employed that comprises a solid-state light source, e.g., a dense array of solid-state light sources. In at least one of such example embodiments, the reaction is a photoreaction associated with the light source.

Methods and systems relating to light sources for use in industrial processes

In order to disinfect and to detoxify a fluid, a photoreactor contains at least two light sources. One light source activates the catalytic function of a semiconductor material in the fluid to reduce the concentration of contaminants in the fluid, such as by breaking down organic contaminants into non-toxic compounds. A second light source acts directly on living biological entities to sterilize or kill them and thereby disinfect the fluid, and can also serve to activate a semiconductor photocatalyst that in turn causes further damage to biological contaminants. The semiconductor photocatalyst is desirably attached to an optically transmitting fiber substrate in the fluid. The second light source in one embodiment is external to the fluid and illuminates the photocatalyst through transmitting surfaces in a fluid containment vessel. The light sources can comprise respective sets of plural LEDs.

Ultraviolet photoreactor for the purification of fluids

The invention consists of a camera, light sources, lenses and software algorithms that are used to image and inspect semiconductor structures, including through infrared radiation. The use of various configurations of solid state lighting and software algorithms enhances the imaging and inspection.

Imaging semiconductor structures using solid state illumination

The present invention provides an optical system having an array of light emitting semiconductor devices to performing an operation that have multiple characteristics associated with performing the operation. The array includes at least one detector located within the array to selectively monitor multiple characteristics of the light emitting semiconductor devices and is configured to generate a signal corresponding to the selected characteristic. A controller is configured to control the light emitting semiconductor devices in response to the signal from the at least one detector. At least one of the multiple characteristics may be concentrated at an area of the array and the at least one detector may be located within the array at the area of the array to selectively monitor characteristic that is concentrated at the area of the array.

Methods and systems relating to solid state light sources for use in industrial processes

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. The array may be connected in series with one or more LED arrays to form a module. Multiple modules may be connected in series with other multiple modules.
