Lamp control function unit for electric lighting subarea control system

Abstract

The invention discloses a lamp control function unit which is applied to an electric lighting zone control system, comprising: a content addressable light control switch device which is used for converting a control command transmited on a bus into a scene control switch signal, transmitting to a lighting scene setting device; a lighting scene setting device which is used for receiving a scene control switch signal of the content addressable light control switch device, decoding lighting scene data signals set by itself, transmitting the decoding result to a light source drive device, driving on-off and brightness of the light source. Utilizing the invention, interfaces of lamps and the lamp control function unit are standardized and simplified, the lamp control function unit adopts different modulating methods for different light sources to get coincident control effect, reduces operation difficulty during applied, reduces manufacturing cost, gives full play to advantages of different light sources, improves quality of lighting, increases energy saving benefit of lighting.

Description

technical field [0001] The present invention relates to the technical field of electric lighting partition control, in particular to a lamp control functional unit applied to an electric lighting partition control system, especially suitable for lighting of lamp controllers that need to set multiple lighting scenes in a digital electric lighting control system. A control switch device, and a light scene setting device interfaced with the light control switch device. Background technique [0002] With the advancement of electronic components and electronic control technology, the electric lighting process has developed into a digital control system, among which the Digital Addressable Lighting Interface (Digital Addressable Lighting Interface, referred to as DALI in Europe and the United States) regulated by Annex E of IEC60929 most representative. This was originally a specification for the purpose of dimming control of fluorescent lamps, but due to its reliability, simplic...

AI Technical Summary

Problems solved by technology

[0020] The 256-step dimming capability is too much for most practical applications in daily life, thus forming a waste

[0021] Compared with the lighting control system based on the computer communication bus, the digital addressable lighting interface control system is much more economical in price, but it is still a relatively expensive system

Especially for developing countries that urgently need automatic lighting control technology to deal with energy-saving issues, the price is unacceptable
