Fig. 1 is a schematic diagram illustrating a structure of an illumination system 100 according to one embodiment of the present disclosure. Wherein the lighting system 100 includes a power module 120, a lamp control module 130, and a plurality of lightheads 140-1 through 140-5. Also shown in fig. 1 is a switch jack 110. The power module 120 has a plug for being plugged into the socket 110 to obtain the mains supply.

Fig. 2 shows a schematic structural diagram of the lamp control module 130 and a schematic connection diagram 200 of the lamp control module 130 to the plurality of lamp heads 140 in detail based on fig. 1, according to one embodiment of the present disclosure.

In fig. 2, the lamp control module 130 includes a controller 131 and a current detection module 132. Optionally, the luminaire control module 130 further comprises a communication module 133. The communication module may be a wireless communication module such as Wi-Fi, zigbee, BLE, or a wired communication module such as DMX, DALI, ethernet, etc. The communication module 133 receives a command from a server side or a hand-held control device such as a mobile phone, and controls the lighting system 100 according to the control command, for example, to switch a plurality of lightheads 140 simultaneously, etc.

Alternatively, if the DC output voltage of the power module 120 is not directly available to the lamp control module 130 and the plurality of lamp heads 140, the lamp control module 130 further includes a DC-DC module 134 for converting the DC voltage from the power module 120 into an appropriate operating voltage for the lamp control module 130 and the lamp heads 140.

In the embodiment shown in fig. 2, the lamp head 140 is an LED lamp, and a plurality of lamp heads 140 are connected in parallel, and are powered by the DC-DC module 134 in the lamp control module 130. The lamp bases 140 are connected in series with the lamp control module 130 through NRZ data lines.

A process of how the controller 131 determines the number of lamp heads connected thereto is described in detail below with reference to fig. 2.

The controller 131 first sends a command to control all lightheads to be in an off state, and then sends a command to control lightheads on-off in sequence.

Fig. 3 shows a schematic diagram of the format of a control command sent by the controller 131 based on the RZ protocol, according to one embodiment of the present utility model, and this implementation of the control command may be provided by SM15155E, a 5-channel low voltage linear driver chip of the single-wire, zero-code protocol. Wherein the control data of each lighthead takes 80 bits, each lighthead 140 in turn obtains the data belonging thereto from the control command. According to the principle of serial connection and the RZ protocol, a first lamp holder can acquire first 80-bit data by itself, a second lamp holder can acquire second 80-bit data by itself, and so on.

The control command sent by the controller 131 is to a plurality of lightheads 140 together at a time, but while one of the lightheads is on, the other lightheads are off. When one lamp is turned on in sequence, the current detection module 132 detects whether or not current flows through the plurality of lamps, and if so, it is considered that one of the lamps has performed a command to switch. If the current is detected until the previous detection and the current detection module 132 does not detect the current after a certain command is sent, the number of the lamp heads is the number of the commands sent before.

The above is a case where the controller 131 sequentially turns on and off the lamps by the plurality of lamp heads 140. In another embodiment, the controller 131 may also let a plurality of lamps turn on simultaneously each time, or turn on all the lamps simultaneously, and set the current level (dimming) of each lamp cap, and determine the number of lamp caps according to the detected total current level.

If the controller 131 can also know the current after each lamp cap 140 is turned on in advance, for example, let each lamp cap turn on at full power, it is also beneficial for the controller 131 to determine the number of lamp caps according to the magnitude of the current detected by the current detection module 132. This is particularly advantageous in case the plurality of lamp bases 140 are of identical gauge.

Fig. 4 shows a circuit embodying the current detection module 132 according to one embodiment of the present disclosure, which is mainly composed of an operational amplifier U5 and a sampling resistor Rcs, and some auxiliary capacitors and resistors.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
