A cascading control method for cascading equipment, cascading equipment, and lighting system

Abstract

The invention discloses a cascade control method of cascade equipment, the cascade equipment and an illumination system. The cascade control method comprises the following steps: judging whether the cascade equipment is in a light source control mode or an address write-in mode through a control signal; when it is judged that the cascade equipment is in the light source control mode, controllinglight source driving modules to enter a dimming control state through a control signal, adjusting the light emitting state of a light emitting module through the light source driving modules, and satisfying the actual dimming control requirement of a user; when the cascade equipment is judged to be in the address write-in mode, transmitting a trigger signal in a plurality of light source driving modules, converting the control signal to obtain a communication clock signal, and realizing an address writing function of the light source driving modules according to a trigger edge counting resultof the communication signal, so that the address writing efficiency and the address writing precision of each light source driving module in the cascade equipment are guaranteed; according to the embodiment, the light source control function and the address write-in function are achieved through the control signal, and the control stability of the light source driving modules is improved.

Description

technical field [0001] The present application belongs to the technical field of light source control, and in particular relates to a cascade control method for cascade equipment, a cascade equipment, and an illumination system. Background technique [0002] With the improvement of the living standard of the national economy and the rapid development of science and technology, light source equipment has been popularized in various technical fields of people's production and life. By driving and controlling the light source equipment in real time, the light source equipment can emit light to meet the needs of users. Actual visual requirements; and the luminous state of the light source equipment has high controllability and flexibility. When the light source equipment is used in different industrial technical fields, technicians can achieve a specific luminous effect by controlling the light source equipment, giving users the best light source. The use brings great convenienc...
