Abstract
The brightness of a Light Emitting Diode is proportional to the forward current. Constant LED forward current provides brightness. Temperature is an important factor in LED color temperature. The color temperature varies when the temperature varies. Therefore, an advanced temperature control scheme is proposed. An Automatic Color Temperature Control Circuit with color temperature compensation is proposed. It is confirmed that the proposed system provides stable color temperature within a temperature range from -30℃ to 85℃.
