ABSTRACT:
A chain controlled lamp stand with multi-stage light modulation includes a control device to modulate brightness of a lamp. The control device consists of a chain-controlled switch and a light modulation circuit board controlled by the chain-controlled switch to modulate the brightness of the lamp. The chain-controlled switch in the lamp stand is combined with a rotatable disc, which can be actuated to rotate at its original location by a pull chain. The rotable disc is assembled thereon with a conducting metal contact strip, and the light modulation circuit board is provided with multi-stage connecting strips, which are able to change, and control voltage waveform. Thus, the metal contact strip is actuated to contact respectively with the multi-stage connecting strips to carry out multi-stage light modulation of the lamp stand.
