摘要： The present disclosure provides methods and structures for controlling characteristics of light being projected from a light source. In one embodiment, the method includes selecting a color setting of light to be projected by a light engine having at least one light emitting diode; and monitoring temperature of the light engine with a thermistor. The changes in resistance measurements taken from the thermistor are correlated to changes in the temperature of the light engine. The method for controlling characteristics of light being projected from the light source may further include setting characteristics of the electrical signal to energize the light emitting diodes of the light engine to provide the color setting selected at the temperature of the light engine measured using the thermistor.

摘要： A lamp including a body for containing a light engine that includes at least a first and second string of said light emitters. The lamp includes driver electronics including an AC-DC switching power supply section of a circuit including a first potentiometer for adjusting total current to the light engine; and a linear topology LED string current control section of the circuit including an operational amplifier controlled by a second potentiometer to operate a field effect transistor (FET) in the linear portion of the FETs operation range to adjust a percentage of the total current to the first and second string of the light emitters. Adjusting the total current adjusts the photosynthetic photon flux (PPF) of light emitted by the lamp. Adjusting the percentage of the total current to the first and second string of the light emitters adjusts the spectral power distribution of light being emitted by the lamp.
