Abstract

A heat lamp is provided that minimizes visual obstructions between an individual and a food service line, while more evenly distributing heat across food. The heat energy penetrates into the food and does not merely heat the surface. Different heating capabilities can be provided by locating the lamp head at different positions over a large adjustable height range. Additional lighting elements provide illumination to heated surfaces to improve visual appeal. Each heat lamp on a service line may be connected to an adjacent heat lamp through built-in power receptacles. The surfaces of the heat lamp are sealed and/or made of easily cleaned substances and have features compliant to one or more industry standards. The heat lamp may be easily transportable and may be resistant to damage.

Claims (21)

1. A heat lamp comprising:

a base comprising an opening in a top surface of the base, wherein the opening receives an end of a support arm;

the support arm coupled to the base via the opening in the top surface of the base, wherein the support arm includes at least two segments, and wherein a first end of a first segment is received by the opening in the top surface of the base to physically couple the support arm to the base; and

an elongated lamp head coupled to a second end of a second segment of the support arm and positioned, via the at least two segments of the support arm, in a plane parallel to the base, the elongated lamp head comprising a heat element linearly aligned with the elongated lamp head and at least one illumination element located within an opening at a distal end of the elongated lamp head, wherein at least one distal end of the elongated lamp head may be selectively positioned at an angle between 0 degrees and 90 degrees with respect to the support arm, wherein the elongated lamp head comprises a rectangular shape, and wherein a first width between parallel long sides of the elongated lamp head is substantially the same as a second width between parallel long sides of the support arm.

2. The heat lamp of claim 1 , wherein the heating element comprises an infrared heating element.

3. The heat lamp of claim 1 , wherein the at least one illumination element comprises a light emitting diode thermally separate from the heating element.

4. The heat lamp of claim 1 , comprising at least a second support arm coupled to the base and having at least two segments and a second lamp head coupled to the second support arm.

5. The heat lamp of claim 1 , wherein the support arm is adjustable to elevate the lamp head in a horizontal position in a specified height range.

6. The heat lamp of claim 5 , wherein the specified height range is between at least 10 inches and 25 inches above a surface upon which the base is located.

7. The heat lamp of claim 5 , wherein the heat lamp remains stable against tipping at maximum reach in all positions within the specified height range.

8. The heat lamp of claim 1 , wherein an outer surfaces of the lamp head remains below a specified temperature at a defined ambient temperature.

9. The heat lamp of claim 1 , wherein the support arm is coupled to the base with at least one pivot recessed into the base.

10. The heat lamp of claim 9 , wherein a pivot of the at least one pivot recessed into the base comprises a first pivot configured to rotate the support arm horizontally within a defined range.

11. The heat lamp of claim 9 , wherein the at least one pivot comprises a second pivot recessed into the base and configured to rotate about a vertical axis perpendicular to the base.

12. The heat lamp of claim 1 , wherein the support arm is coupled to the base with:

a first pivot configured to rotate the support arm horizontally within a defined range; and

a second pivot configured to rotate about a vertical axis perpendicular to the base.

13. The heat lamp of claim 1 , comprising an outer surface having a fingerprint resistant finish.

14. The heat lamp of claim 13 , wherein the fingerprint resistant finish comprises at least one of plastic, aluminum, stainless steel, or nickel.

15. The heat lamp of claim 1 , wherein the at least one illumination element comprises a light emitting diode having a color temperature of about 3000 Kelvin.

16. The heat lamp of claim 1 , further comprising a tilt sensor, wherein operation of the heat element is disabled when the tilt sensor output is indicative of a predefined tilt.
