This is the future development trend of stage lighting.
[0003] Even with today's waterproof lighting fixtures, performances and exhibitions still require connectors and cables. Besides the waterproof lighting fixtures, numerous connectors and cables are also required.

[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] In the present invention, it needs to be explained that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

The microwave communication module is provided with a signal receiving circuit 31 for receiving an external trigger signal and converting the trigger signal into a microwave drive signal and a microwave communication circuit 32 for receiving a microwave drive signal and converting the microwave drive signal into microwave data to start the waterproof lamp body.
[0024] The base 2 includes a base upper cover 21 and a base lower cover 22.

In addition, the waterproof lamp body can be fixed by the base upper cover through bolts or screws, and the base lower cover can be fixed to the stage lighting stand through bolts or screws.
[0025] Waterproof glass 5 is installed between the base and the waterproof lamp body. The first waterproof glass 51 mounts the microwave communication circuit on the waterproof lamp body, and the second waterproof glass 52 mounts the signal receiving circuit on the base. Aligning the microwave communication circuit and the signal receiving circuit ensures stable signal transmission.
[0026] like Figure 2 As shown, the signal receiving circuit includes a conversion chip U3 and a control chip U4. The B and A pins of the conversion chip U3 receive external trigger signals through interfaces DMX1 and DMX2, which are converted and output by the RXD and TXD pins of the conversion chip U3 to the control chip U4. The PA2 and PA3 pins of the control chip U4 receive the RXD and TXD signals of the conversion chip, which are converted into microwave driving signals by the control chip U4 and transmitted to the microwave communication circuit through the TX and RX interfaces of the PB10 and PB11 pins of the control chip U4.

[0029] The first level conversion chip U1 and the second level conversion chip U2 are level conversion ICs. They receive data from the control chip U4 and convert the voltage of the external trigger signal from 3.3V to 1.8V. This processed signal can then be transmitted to the microwave data conversion chip SKA2P1, which converts it into a microwave signal for transmission. The SYS_WKP interface of the microwave data conversion chip SKA2P1 is the data receiving and transmitting port, which transmits and receives data. The RESET interface of the microwave data conversion chip SKA2P1 is a reset interface that can be pulled high to reset the entire microwave communication system. The MGT interface of the microwave data conversion chip SKA2P1 controls the reception and transmission of signals in the microwave communication system. When MGT is pulled low, the microwave communication system is in the receiving state; when MGT is pulled high, the microwave communication system is in the transmitting state. The first level conversion chip U1 and the second level conversion chip U2 can be RS0102 level conversion chips, and the microwave data conversion chip can be SKA2P1 microwave data conversion chips.
[0030] like Figure 4 As shown, the management circuit includes a power management chip U8, and the battery pack control circuit includes a first MOS transistor Q4, a second MOS transistor Q5, a third MOS transistor Q6, and a fourth MOS transistor Q7; the FB2 pin of the power management chip is electrically connected to the battery pack, the ENB pin is electrically connected to the battery pack, the HD1 pin is electrically connected to the gate of the first MOS transistor Q4, the HD2 pin is electrically connected to the gate of the second MOS transistor Q5, the LD1 pin is electrically connected to the gate of the fourth MOS transistor Q7, the LD2 pin is electrically connected to the gate of the third MOS transistor Q6, the SW1 pin is electrically connected to the source of the first MOS transistor Q4 and the drain of the fourth MOS transistor Q7, and the SW2 pin is electrically connected to the source of the second MOS transistor Q5 and the drain of the third MOS transistor Q6; the source of the first MOS transistor Q4 and the source of the second MOS transistor Q5 are electrically connected via an inductor L3; the sources of the third MOS transistor Q6 and the fourth MOS transistor Q7 are both grounded; the drain of the first MOS transistor Q4 is electrically connected to the waterproof lamp via VDD; and the drain of the second MOS transistor Q5 is electrically connected to the battery pack. A first resistor R66, a second resistor R67, and a third resistor R68 are provided between the FB2 pin of the power management chip and the battery.

The other end of the second resistor is electrically connected to the battery pack. One end of the third resistor is electrically connected to the FB2 pin of the power management chip, and the other end is grounded. The power supply circuit also includes a transistor Q8. The base of the transistor is electrically connected to the control interface, the collector is electrically connected to the ENB pin, and the emitter is grounded. The OTG pin of the power management chip is grounded via a current-limiting resistor.

A 100K resistor can be used for the first resistor R66, a 12K resistor can be used for the second resistor R67, and a 6K8 resistor can be used for the third resistor R68.
[0032] When the NEB pin is pulled high, the emitter S and collector D of transistor Q8 conduct, pulling the ENB pin of power management chip U8 low, and the battery pack control circuit operates normally. When the NEB pin is pulled low, the emitter S and collector D of transistor Q8 are not conducting, pulling the ENB pin of power management chip U8 high, and the battery pack control circuit enters sleep mode. Furthermore, by controlling the OTG pin, the battery pack can be controlled to power the waterproof lighting fixture through the battery pack control circuit, or an external power source can be controlled to charge the battery pack through the battery pack control circuit. When the OTG pin is pulled low, the OTG pin of power management chip U8 is also pulled low, allowing the battery pack to output voltage to the waterproof lighting fixture through VDD controlled by the battery pack control circuit. When the OTG pin is pulled high, the OTG pin of power management chip U8 is also pulled high, allowing an external power source to charge the battery pack through the battery pack control circuit.
