摘要：
An amalgam fluorescent lamp is designed to operate with minimum axial illumination variations when changing from an off to an on state. This is accomplished by incorporating at least three amalgam patches internal to the lamp. Two patches are located at opposite ends of the lamp, and at least a third patch is centrally located. Each patch has an associated thermistor ands external heater sleeve. The patch temperature which correlates wiht the optimum lamp operating temperature is continuously monitored and adjustments are made to the heater sleeve elements to maintain the patches at desired optimum temperature.
