Abstract
An embodiment provides a lamp apparatus, including: at least one filament; an amount of amalgam; a heat-sink assembly connected to the lamp apparatus; and at least one control circuit comprising a heating element and a temperature measurement element connected to the at least one filament, wherein the control circuit varies the electrical power delivered to the heating element, thereby controlling an internal temperature of the lamp apparatus relative to a temperature set point. Other aspects are described and claimed.
Claims18
A lamp apparatus, comprising:
- at least one filament;
- an amount of amalgam;
- a heat-sink assembly connected to the lamp apparatus;
- a data connection, wherein the data connection transmits and receives external device data;
- and
- at least one control circuit comprising a heating element and a temperature measurement element connected to the at least one filament, wherein the control circuit varies the electrical power delivered to the heating element, thereby controlling an internal temperature of the lamp apparatus relative to a temperature set point.
A method for controlling an internal temperature of a lamp:
- measuring a temperature of the lamp apparatus, wherein the lamp comprises at least one filament, an amount of amalgam, a heat-sink connected to the lamp, and at least one control circuit comprising a heating element and a temperature sensing element connected to the at least one filament;
- comparing the measured temperature of the lamp to a temperature set-point;
- and
- controlling, using the at least one control circuit and a data connection, the measured temperature of the lamp based upon the comparing, wherein the data connection transmits and receives external device data.
A product for controlling a lamp, comprising:
- a storage device that stores code, the code being executable by a processor and comprising:
- code that measures the internal temperature of the lamp, wherein the lamp comprises at least one filament comprising an amount of amalgam, a heat-sink connected to the at least one filament, and at least one control circuit comprising a temperature sensing element and a heating element, connected to the at least one filament;
- code that compares the measured temperature of the lamp to a temperature set-point;
- and
- code that controls, using at least one of:
- the heat-sink and the at least one control circuit, the internal temperature of the lamp based upon the comparing.
