Abstract

The invention relates to a control system. The control system comprises a light transducer, a light modulator electrically connected with the light transducer, a transformer electrically connected between the light modulator and light transducer in series, the dummy load circuit connected with the light transducer in parallel, a control circuit connected with a detection filter circuit and used for converting light angle adjusting signals into control signals, and a switch load circuit connected with the control circuit, wherein the dummy load circuit comprises the detection filter circuit connected with the transformer and used for detecting light adjusting angles of the input voltage from the transformer and generating light adjusting angle signals, and the switch load circuit comprises a load, and the load current passing the load is changed according to the control signals.

Description

technical field [0001] The invention relates to a control system, a dummy load circuit and a dummy load control method, in particular to a control system for adjusting lamp brightness, a dummy load circuit and a dummy load control method. Background technique [0002] Currently, LED (Light-Emitting Diode, light-emitting diode) lamps are widely used instead of halogen lamps because of their higher power efficiency and longer lifespan. LED lamps are generally three to six times more efficient than incandescent halogen lamps. LED lights have lower wattage and are therefore more energy efficient. [0003] In addition to the advantages of energy saving, users still hope that LED lamps can have some advantages of halogen lamps, especially the brightness of the light can be adjusted. At present, the control system for controlling the LED lamp includes a dimmer and a transformer. The dimmer adjusts the input voltage to adjust the brightness of the LED lamp. The lower the power of ...
