The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
Fig. 1 is a block diagram of an LED dimming and toning circuit according to an embodiment of the present invention. Referring to fig. 1, the LED dimming and toning circuit specifically includes:

Therefore, in the embodiment of the invention, a plurality of ports can be arranged to realize signal output or input of different transmission paths, any port can be multiplexed, and the number of the ports used can be greatly reduced after multiplexing, so that the LED dimming and toning circuit provided by the invention has smaller size. In addition, the invention also provides a scheme for selecting different paths according to different modes, and the embodiment of the invention can realize the process control of dimming and toning of the LED more flexibly.
The following describes the technical scheme of the invention. Continuing to refer to fig. 1, the LED dimming and toning circuit in an embodiment of the present invention may further include: and the function selection circuit 10, wherein the singlechip in the main control circuit is also connected with the function selection circuit, and the function selection circuit realizes communication with the singlechip through wireless transmission or wired transmission.
In other alternative embodiments, the LED dimming and toning circuit further comprises: and a signal isolation circuit 70 connected to the receiving circuit 60, the signal isolation circuit 70 being configured to isolate the received signal.
It should be noted that the LED dimming and toning circuit may have two different modes, one is DALI bus mode, in which dimming and toning (e.g. dimming in DT6 or dimming and toning in DT8 functions) can be achieved by the transmitted control signal; the other is PUSH mode, in which the DALI bus and auxiliary power supply are turned off, and when the input signal is detected as DIM, the LED is adjusted in brightness, and when the input signal is detected as CCT, the LED is adjusted in color temperature.
Specifically, when in the DALI bus mode, the user can select whether to turn on the auxiliary power supply and the DALI bus power supply using the function selection circuit 10 with the signal in the DALI bus mode as the dimming signal. When the DALI bus power is selected not to be on, a bus power external to the DALI is required at this time to achieve power supply to the overall circuit, and the functionality of DT6 and DT8 is achieved through DALI bus protocol communication.
When the main control circuit is in the PUSH mode, the singlechip controls the bus power supply and the auxiliary power supply to be turned off, different signals in the PUSH mode are used as dimming signals, if the input signal is DIM (the channel), the program enters dimming, and if the input signal is CCT, the color matching is carried out, and because of the input channels of the two signals, the functions of DT6 (dimming) and DT8 (dimming and color matching) can be realized in the PUSH mode.
Based on the differences between DALI bus mode and PUSH mode, the two modes may correspond to different paths, respectively. Optionally, the first path is used to implement the PUSH mode and the second path is used to implement the DALI bus mode.

In an alternative implementation of the present invention, the plurality of ports further includes: a common port 53 for being multiplexed to achieve power sharing or signal sharing.

In addition, the invention also provides a scheme for selecting different paths according to different modes, and the embodiment of the invention can realize the process control of dimming and toning of the LED more flexibly. In addition, the invention integrates DALI dimming DT6 and DT8 functions, PUSH dimming and toning functions, DALI bus power supply and auxiliary power supply circuit functions, can effectively reduce the use of external ports, and has important significance for miniaturization and platformization of products.
