Abstract
The present invention is a device for sterilizing microorganisms on a liquid or solid substrate. The device includes a light source for producing a light and an optical device positioned proximate the light source. The optical device is configured to focus the light generated by the light source to provide a high intensity light output. The optical device also includes a dichroic reflector. The dichroic reflector is configured to pass thermal energy generated by the light source and reflect the light produced by the light source. The device also includes a power supply, where the power supply is coupled to the light source and the optical device. The device thereby killing microbial organisms presented within the range of the high intensity light output.
Claims24
A system for sterilizing microorganisms on a heat sensitive liquid or solid substrate, the system comprising:
- a. a high intensity light source for producing a UV light;
- b. a dichroic reflector positioned proximate the light source, wherein the dichroic reflector is configured to focus the reflected light produced by the light source to a first end of light guide wherein the light guide delivers the light at a second end to provide a high intensity light output to the liquid or solid substrate;
- and wherein the dichroic reflector is configured to pass thermal energy produced by the light source through the dichroic reflector;
- and reflect the light produced by the light source to the light guide;
- c. a power supply, wherein the power supply is coupled to the light source and the dichroic reflector;
- d. the light guide for receiving the high intensity light output focused from the dichroic reflector and deliver it from the light guide second end to the heat sensitive liquid or solid;
- and
- wherein the microorganisms within the range of the high intensity light output from the light guide are killed.
A method for providing microbiological sterilization on a heat sensitive liquid or solid substrate comprising the steps of:
- a) providing a device for sterilizing microorganisms on a heat sensitive liquid or solid, wherein the device includes:
- i. a high intensity light source for producing a UV light;
- ii. a dichroic reflector positioned proximate the light source, wherein the dichroic reflector is configured to focus the reflected light produced by the light source to a first end of light guide wherein the light guide delivers the light at a second end to provide a high intensity light output to the liquid or solid substrate;
- and wherein the dichroic reflector is configured to pass thermal energy produced by the light source through the dichroic reflector;
- and reflect the light produced by the light source to the light guide;
- iii. a power supply, wherein the power supply is configured to couple to the light source;
- b) activating the light source for a predetermined period to provide an exposure period greater than approximately 0.01 seconds;
- c) positioning the output of second end of the light guide a predetermined distance from the heat sensitive substrate to be treated;
- d) exposing the surface to be treated to the high intensity light output;
- and
- e) deactivating the light source, having sterilized any microbiological agents existing on the substrate.
