摘要： The invention discloses a drive circuit, a related circuit and a device. The drive circuit comprises: a load current control circuit, a rectifier module, an energy storage component and a charge-discharge generating circuit, wherein: the charge-discharge generating circuit is connected to the energy storage component and the load current control circuit; the energy storage component and the charge-discharge generating circuit are connected at both ends of the rectifier module; the charge-discharge generating circuit is configured to: form a charging loop with the energy storage component during a charging process of the energy storage component, and control a charging current of the energy storage component; and form a discharging loop with the energy storage component during a discharging process of the energy storage component. The above-mentioned drive circuit provided by the embodiment of the present disclosure can eliminate the current ripple in the circuit, ensure the stability of the controlled load, and the AC input current and the AC input voltage have a common axis of symmetry, thereby improving the PF.

摘要： Apparatus and associated methods involve a hangable LED light assembly constructed to provide a selected color output illumination as a function of excitation intensity. In an illustrative example, the color output may be selected to promote biological development throughout livestock development stages (e.g., incubation, growth, and reproduction). The light intensity may controllable, for example, in response to a light dimmer arranged to modulate AC excitation applied to the LED downlight. As the light intensity is decreased in response to a simple dimmer control, the spectral output of the LED downlight may shift its output wavelengths. Accordingly, some exemplary installations may provide controlled combinations of intensity and color to substantially optimize lighting conditions for livestock.

摘要： The invention discloses an electrical appliance of an LED dimmer working in conjunction with a line reactor, comprising a power supply, a dimming control circuit, a line reactor circuit and a voltage converting circuit. Output end of the power supply is connected to the dimming control circuit, output end of the dimming control circuit is connected to the line reactor circuit, output end of the line reactor circuit is connected to the voltage converting circuit, and output end of the voltage converting circuit is connected to electrical loads. In the present invention, a utility frequency line reactor is series connected between the output end of the dimmer and the dimmable LED light, and a R.C peak voltage absorption circuit is parallel connected to both ends of the line reactor. By switching the phase angle on and off, it is possible to adjust level of output voltage and make light adjustment. In the meantime, harmonic current is reduced, and consequently electric grid pollution and line loss relieved, and finally energy is saved and pollution is controlled.
