The utility model relates to LED lighting technical field discloses a layered controllable LED lamps and lanterns and
cascade control system. The lamps and lanterns include casing and circuit board, and the circuit board integrates drive module,
LED lamp set and
power module. Drive module is connected with the distribution address code through
single line communication
bus series connection multiple LED drive
chip, and the first
chip is connected with external code writer and is distributed address code, and
LED lamp set is equipped with multiple sections of addressable light emitting circuit, and each circuit contains RGB LED unit and is independently controlled current control. The
power module guarantees power supply stability through filter unit. The casing is equipped with detachable
assembly structure and limiting clamping groove. In the
cascade control system, each lamps and lanterns is connected through
chip pin and forms
cascade link. The utility model realizes layered independent control, reliable
signal transmission and accurate current drive, supports dynamic light effect, modular extension, solves the problems of insufficient control flexibility of traditional lamps and lanterns, poor
signal transmission reliability and the like, and is suitable for advertisement decoration,
stage lighting and the like scenes.
