Abstract

Claims (15)

1. An apparatus comprising:

a) a housing;

b) a chamber disposed in the housing, the chamber configured to be adaptable to each of an open configuration, a closed configuration, and a hermetically sealed configuration, wherein the chamber comprises a material transparent to actinic radiation;

c) at least two light emitting diodes (LEDs) disposed within the housing, wherein light from the at least two LEDs enters the chamber from more than one direction, wherein a first LED is positioned to direct light through a first major surface of the chamber and a second LED is positioned to direct light through an opposing second major surface of the chamber;

d) a user interface disposed on an exterior of the housing, the user interface comprising a display and a plurality of program switches configured to adjust at least three operational parameters of the apparatus, wherein the at least three operational parameters comprise; 1) light intensity provided by the at least two LEDs, 2) length of time of light provided by the at least two LEDs, and at least one of: 3a) a first delay time parameter corresponding to a delay time between initiation of light provided by the at least two LEDs and initiation of vacuum pulled on an interior of the chamber, or 3b) a second delay time parameter corresponding to a delay time between initiation of vacuum pulled on the interior of the chamber and initiation of light provided by the at least two LEDs;

e) a vacuum pump operatively connected to the chamber; and

f) a processor electronically coupled to the user interface, wherein the processor causes the at least two LEDs to emit light and the vacuum pump to operate according to a program inputted through the plurality of program switches, and wherein the processor is configured with one or more preconfigured values for at least one of the first delay time parameter or the second delay time parameter.

2. The apparatus of claim 1 , wherein the processor further comprises a memory storing the program and is configured to cause the at least two LEDs to emit light and the vacuum pump to operate according to the program.

3. The apparatus of claim 1 , wherein the user interface comprises a touch screen that provides the display and the plurality of program switches.

4. The apparatus of claim 1 , further comprising a third LED positioned to direct light through a third major surface of the chamber, wherein the third major surface is directly adjacent to each of the first major surface and the second major surface.

5. The apparatus of claim 1 , wherein the chamber further comprises a connector configured to attach a gas source to the chamber.

6. The apparatus of claim 5 , wherein the plurality of program switches is further configured to adjust time of flushing the chamber with a gas from the gas source, pressure of flushing the chamber with the gas, or both.

7. The apparatus of claim 1 , wherein the vacuum pump is configured to achieve an absolute pressure inside the chamber of 0.1 to 30 millibars (mbar).

8. The apparatus of claim 1 , wherein the one or more preconfigured values correspond to a predetermined time range or discrete time intervals.

9. The apparatus of claim 1 , wherein the program is entered via the user interface, wherein the processor is configured to initiate the program using an activation mechanism, and wherein the activation mechanism, when activated, causes the at least two LEDs and the vacuum pump to operate according to the program.
