Abstract

A modular photochemical reactor system having a plurality of fluidic modules each having i) a central planar process fluid layer and ii) two outer planar thermal control fluid layers for containing flowing thermal control fluid and a plurality of illumination modules, the illumination modules of the plurality each having a planar form with first and second major surfaces and each having at least a first array of semiconductor emitters, the emitters positioned to emit from or through the first major surface, wherein the first array of semiconductor emitters has at least a first emitter and a second emitter, the first emitter capable of emitting at a first center wavelength and the second emitter capable of emitting at a second center wavelength, the first and second center wavelengths differing from each other.

First claim

What is claimed is:

1. A modular photochemical reactor system comprising:
a plurality of fluidic modules each having i) a central planar process fluid layer and ii) two outer planar thermal control fluid layers for containing flowing thermal control fluid; and
a plurality of illumination modules each having a planar form with first and second major surfaces, and each comprising at least a first array of semiconductor emitters, said emitters capable of emitting at visible and/or UV wavelengths and being positioned to emit from or through the first major surface and through the outer planar thermal control fluid layer of a fluidic module of the plurality of fluidic modules to the central planar process layer of the fluidic module of the plurality of fluidic modules, wherein said first array of semiconductor emitters comprises at least a first emitter and a second emitter, the first emitter capable of emitting at a first center wavelength and the second emitter capable of emitting at a second center wavelength, said first and second center wavelengths differing from each other.

2. The system according to claim 1 wherein said first array further comprises at least a third emitter capable of emitting at a third center wavelength, said third center wavelength differing from each of the first and second center wavelengths.

3. The system according to claim 1 wherein the emitters comprise individually packaged emitters.

4. The system according to claim 1 wherein the emitters comprise emitters packaged in groups and wherein said groups-contain at least one first emitter and at least one second emitter.

5. The system according to claim 1 wherein said at least one first emitter within said first array is connected to a first power or control line and said at least one second emitter within said first array-is connected to a second power or control line.

6. The system according to claim 1 wherein the plurality of illumination modules comprises at least one illumination module which itself further comprises a second array of semiconductor emitters capable of emitting at visible and/or UV wavelengths and positioned to emit from or through the second major surface, said second array of semiconductor emitters comprising at least one first emitter and at least one second emitter.

7. The system according to claim 6 wherein said at least one illumination module of said plurality of illumination modules further comprises a heat exchanger including a cooling fluid passage therein having inlet and outlet ports, the heat exchanger being in thermal contact with the emitters of the first array and with the emitters of the second array.

8. The system according to claim 1 wherein said illumination modules of said plurality each further comprise a heat exchanger including a cooling fluid passage therein having inlet and outlet ports, the heat exchanger being in thermal contact with the emitters-of the first array.

9. The system according to claim 1 , wherein the emitters are light emitting diodes (LEDs).

10. The system according to claim 9 wherein the LEDs are capable of providing at least of 40 mW/cm2 to an area free of inlet and outlet ports of the first or second major surface of the fluidic module of the plurality of fluidic modules.
