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

Embodiment Construction
[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0057] For ease of description, this embodiment will use lighting scene commands compatible with the Digital Addressable Lighting Interface (DALI), as shown in Table 2 and Table 3, where Table 2 is the system command, and Table 3 is the interval command.
[0058] For example, the system-wide broadcast command of the present invention can be defined as two bytes, and the first byte is FF, as shown in Table 2:
[0059] turn off
FF00

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, drivingon-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...
