Dimming and toning system

Abstract

The invention discloses a dimming and toning system. The dimming and toning system comprises a central control board, a controller, one or more decoders and one or more light-emitting diode (LED) lamps corresponding to each decoder; the central control board is used for sending a control command; the control command comprises mode information corresponding to a control mode and service information of a service to be executed in the corresponding control mode; the controller is used for receiving the control command and resolving the service information according to the mode information so as to acquire a driving signal of the service to be executed in the control mode; and each decoder acquires a duty ratio signal corresponding to each light source of each LED lamp according to the driving signal, and controls each light source of current each LED lamp according to the corresponding duty ratio signal. The dimming and toning system can be used for controlling the brightness, tone and color of lamps.

Description

technical field [0001] The invention belongs to the field of semiconductor lighting and relates to a dimming and color matching system. Background technique [0002] In recent years, with the in-depth development of my country's economic reform, the construction of the city's overall image project has also been valued by governments at all levels. As an important part of the image project, urban lighting has been paid more and more attention by the government, and a large amount of funds have been invested in construction and renovation. Urban night scene lighting should be closely integrated with urban planning and is an integral part of urban lighting. Urban night scene lighting must not only have reasonable lighting functions, but also need to have a high artistic level. [0003] At the same time, this puts forward higher requirements for the management of urban night scene lighting. It is necessary to use modern control technology for scientific management, which can n...

Problems solved by technology

[0004] At present, the control of urban night scene lighting and landscape lamps is mainly to turn on or off the lamps through the central console, and the brightness, tone, and color of the lamps cannot be controlled. In this single management method, it is obviously impossible to obtain good results. lighting effects

[0005] When it is necessary to change the lighting effect, such as flickering, color change, etc., or to change the simple control such as the color and tone of the lamp, the existing on or off control method is obviously not satisfactory, and only by replacing the lamp of the corresponding color, or through Adjusting the lamps one by one by manual setting brings great inconvenience and high maintenance cost
