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.

A system for generating a low thermal energy high intensity UV light 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) at least one dichroic reflector positioned proximate the light source, wherein the dichroic reflector is configured to focus the reflected light produced by the light source to provide a low thermal energy high intensity light output to be delivered 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 low thermal energy high intensity UV light;
- and
- c) a power supply, wherein the power supply is coupled to the light source;
- and
- wherein the microorganisms within the range of the delivered high intensity light output are killed.
A method for providing a low thermal energy, high intensity UV light for microbial sterilization on a heat sensitive substrate comprising the steps of:
- a. providing a device which produces a low thermal energy, high intensity UV light, wherein the device includes:
- i. a high intensity light source for producing a UV light;
- ii. at least one dichroic reflector positioned proximate the light source, wherein the dichroic reflector is configured to focus the reflected light produced by the light source and wherein the at least one dichroic reflector is configured to pass thermal energy produced by the light source through the dichroic reflector;
- and
- iii. a power supply configured to couple the light source;
- b. activating the light source;
- and
- c. taking the focused light and delivering it to the substrate to expose the substrate to the low thermal energy, high intensity UV light.
A method for delivering a high energy UV light to a substrate comprising:
- a. selecting a high energy light that emits a high energy UV light;
- b. removing the thermal energy produced by the high energy UV light;
- and
- c. delivering the high energy light without thermal energy to the substrate.
