Abstract: An LED driver capable of controlling color/color temperature with a power carrier connects a power switch with a dimmer for linking an input end of an LED color/color temperature output controller. An LED array disposed on an output end of the controller allows a power cord to transmit a controlling signal. A synchronous and dimmer action detection differentiates an action of the dimmer or pressing times from an ON/OFF count, so that the LED array presents different color temperatures/colors accordingly. An LED condition memory saves the color temperature/color according to an output signal. In adjusting illumination, the dimmer changes an output current for altering the power of the LED array accordingly, which presents a stable light but avoids deviating the color temperature/color and flickering.

Abstract: A halogen lamp electronic transformer a power supply circuit, a voltage divider circuit, a control circuit, inductive coils, a push pull oscillator circuit, and a triggering and overload protection circuit. The push pull oscillator circuit consists of a plurality of push pull oscillator transistors, the bases of which are respectively connected to the positive ends of a plurality of inductive coils, with their emitters connected to the negative ends. As such, the positive electrical potential polarity reversal induced at the positive end of the plurality of inductive coils and the negative electrical potential reversal induced at the negative end of the inductive coils switch out and connect the plurality of push pull oscillator transistors to provide for the alternating continuity and cut off of the push pull transistors. This enables the reverse polarity of voltage dividing by the plurality of inductive coils and provides for the current dividing of the current flowing through the push pull oscillator transistors which reduces the heat generated by the push pull oscillator transistors and prolongs their service life.

Abstract: An electronic ballast capable of linear and stepless light regulation that utilizes a chopped positive pulse passing through a limiting inductor and through two cathode coils of a fluorescent tube to a first mutual inductor and passing through a second transistor to excite the fluorescent lamp to radiate light. The luminosity is dependent upon the size of the portion of the positive pulse of the sinusoidal wave that is chopped. The chopped positive pulse utilizes the counter electromotive force generated by a first mutual inductor with respect to second and third mutual inductors to form semi-symmetrical resonance to maintain the pulse signals that pass through the fluorescent lamp to thereby continuously excite the cathode coils of the fluorescent lamp so that the latter always has the required luminosity. In this way, chopped power source waveforms are used to achieve linear light regulation so as to achieve zero dissipation, non-flashing during light regulation, and an increased light regulation range.
