The application provides an ink cartridge chip applied in an ink cartridge which is detachably installed in an imaging device. The ink cartridge chip includes an interface unit and a control unit. The interface unit receives a light control command from the imaging device, which may be a light-lighting-up or a light-extinguishing command. The control unit is connected to a light-emitting unit, and lights up the light-emitting unit on detecting that the ink cartridge chip is in a power-up initialization stage. And the control unit is also connected to the interface unit, and determines, in a case that the light control command is a light-extinguishing command, whether a preset extinguishing condition is satisfied, extinguishes the light-emitting unit if the preset extinguishing condition is satisfied, and maintains a current state of the light-emitting unit if the light control command is a light-lighting-up command.

Ink cartridge chip applied in ink cartridge, ink cartridge, and ink cartridge adapter

An ink cartridge chip includes an interface unit, a control unit, and a storage unit, wherein the interface unit is configured to receive a light control command sent from an imaging device, and the light control command includes ink cartridge identification information; the storage unit is configured to store autogenic identification information and a state flag, and the state flag includes an executable state or a non-executable state; the control unit is configured to execute the light control command; and the control unit is is configured to, when the interface unit receives the light control command, control the light-emitting unit to execute the light control command based on the type of the light control command and the state flag in the storage unit to re-determined the state flag.
