## Abstract

A photoemission radiant heater includes a chamber having an interior reflective surface, a first end and a second end; a means for generating photons within the chamber wherein photons are reflected off the interior reflective surface of the chamber; a black body means having a portion thereof located in a position to absorb radiant energy from within the reflective chamber; means for blowing air over the black body means wherein heat is transferred from the black body means to the air. A means for concentrating photons such as a lens or convex reflective shield may be included within the chamber and the black body means may be located either within the core of the chamber, or at a first end of the chamber where it may or may not contain a plurality of members which extend out of the chamber axially along the length of the chamber. Air is blown over the black body means to absorb energy therefrom.

## Claims

### Claim 1

A photo emission radiant heater comprising:
an elongate and cylindrical reflective chamber having an interior reflective surface;
means for generating photons within the reflective chamber wherein photons are reflected off the interior reflective surface of said reflective chamber;
a black body means having a portion thereof located in a position to absorb radiant energy generated by the reflection of photons off the reflective surface of said reflective chamber; and
means for blowing air over the black body means wherein heat is transferred from the black body means to the air.

### Claim 2 (depends on 1)

The photoemission radiant heater of claim 1 further comprising a means for concentrating photons towards the black body means.

### Claim 3 (depends on 2)

The photoemission radiant heater of claim 2 wherein the means for concentrating photons towards the black body means comprises a lense.

### Claim 4 (depends on 2)

The photoemission radiant heater of claim 2 wherein the means for concentrating photons towards the black body means comprises a convex reflective shield.

### Claim 5 (depends on 2, 4)

The photoemission radiant heater of claims 2 or 4 wherein the black body means is located within the chamber.

### Claim 6 (depends on 2, 4)

The photoemission radiant heater of claims 2 or 4 wherein the black body means is located at a first end of the chamber.

### Claim 7 (depends on 2, 4)

The photoemission radiant heater of claims 2 or 4 wherein the black body means further comprises a second portion thereof located outside of the chamber.

### Claim 8 (depends on 7)

The photoemission radiant heater of claim 7 wherein the second portion of the black body means located outside of the chamber comprises a plurality of members extending axially outside of the chamber.

### Claim 9 (depends on 8)

The photoemission radiant heater of claim 8 wherein the black body means comprises a disk shaped member located at the first end of the chamber.

### Claim 10 (depends on 1, 4)

The photoemission radiant heater of claims 1 or 4 wherein the means for generating photons within the chamber comprises a light bulb.

### Claim 11 (depends on 10)

The photoemission radiant heater of claim 10 wherein the light bulb is located towards a second end of the chamber.

### Claim 12 (depends on 1)

The photoemission radiant heater of claim 1 wherein the black body means comprises a polymer filled black body.

### Claim 13 (depends on 1)

The photoemission radiant heater of claim 1 further comprises a means for regulating blowing air over the black body means.

### Claim 14 (depends on 9)

The photoemission radiant heater of claim 9 further comprising one of a steel or cast iron receiver affixed to the disk shaped member.

### Claim 15 (depends on 8)

The photoemission radiant heater of claim 8 wherein said members comprise aluminum rods.
