Fig. 1 is a schematic structural diagram of a lamp provided by an embodiment of the present application. As shown in Figure 1, the lamp includes a light emitting element 11; a ballast 12, the ballast 12 is connected with the light emitting element 11, and is used to control the lighting and extinguishing of the light emitting element 11; MCU13, the MCU13 is connected with the ballast 12, It is used to send a control signal to the ballast 12 when it is determined that the light-emitting element 11 cannot be controlled by the lighting console, and the light of the light-emitting element 11 can exit the lamp, so that the ballast 12 controls the light-emitting element 11 goes out.

Wherein, the light emitting element 11 may be a light bulb, which is a light emitting device in a lamp. The ballast 12 may be an electronic ballast, which drives the light source through electronic technology and controls the lighting and extinguishing of the light emitting element 11 . MCU13 can be an MCU with a display panel, through which the current status of the lamp can be displayed. Optionally, an indicator light can be set to display the current status of the lamp. For example, when the status of the lamp is normally controlled by the remote lighting console, the indicator light is off , when the lamp fails and cannot be controlled by the lighting console, the indicator light flashes to remind.

Under normal circumstances, the lighting console controls the normal operation of the lamps by sending DMX512 signals. When the lamps fail and cannot be controlled by the remote console, the lamps need to be extinguished to avoid uncontrolled irradiation of the lamps on other objects. When the MCU13 determines that the light-emitting element 11 cannot be controlled by the lighting console, and at the same time, when the light of the light-emitting element 11 can exit the lamp, the MCU13 sends a control signal to turn off the light bulb to the ballast 12, and the ballast 12 receives the signal to turn off the light bulb. After the control signal of the light bulb, the light-emitting element 11 is controlled to be extinguished, and at the same time, a signal of successfully extinguishing the bulb is fed back to the MCU13.

In the above embodiment, the lamp includes a light-emitting element, a ballast, and the ballast is connected with the light-emitting element for controlling the lighting and extinguishing of the light-emitting element; it also includes an MCU, and the MCU is connected with the ballast for determining that the light-emitting element cannot When it is controlled by the lighting console and the light of the light-emitting element can exit the lamp, the MCU sends a control signal to the ballast, and the light-emitting element is controlled to be extinguished through the ballast. In this way, during the use of the luminaire, when the luminaire cannot be remotely controlled by the lighting console due to failure or other reasons, the MCU built in the luminaire will judge the status of the luminaire to determine if the luminaire cannot be controlled by the lighting console. When the light can be emitted outside the lamp, send a control signal to the built-in ballast of the lamp to control the light-emitting element of the lamp to extinguish, so that the lamp can be extinguished without powering off the faulty lamp through the power silicon box, realizing the protection of the lamp Independent control, more convenient to use.

In an optional implementation, the MCU 13 is specifically used to determine the light emitting element 11 when no new DMX512 signal sent by the lighting console is received within a preset period of time after receiving the DMX512 signal sent by the lighting console. Cannot be controlled by lighting console.

Wherein, the preset duration is the transmission time of one DMX512 data packet. As shown in Figure 2, it is the structure of a DMX512 data packet. MTBP (Mark Time Between Packets) marks that a complete DMX512 data packet has been sent, and it is a free bit for the next DMX512 data packet. MTBP is active at high level. Optionally, the lighting console can be connected to the lamps through the DMX512 signal line, the lighting console continuously sends DMX512 data packets to the lamps, and the MCU13 detects the MTBP bit of the DMX512 data packets and receives the DMX512 data packets. A DMX512 data packet consists of 1 MTBP bit, 1 Break bit, 1 MAB, 1 SC and 512 data frames. The transmission rate of DMX512 data packets is fixed at 250Kbps, the time of each data bit is 4μs, and each data frame is 11 bits, which is 44μs. That is, the data transmission time of 512 data frames is 44*512=22.528ms. It can be seen from the above that the transmission time of a DMX512 data packet is 88μs+8μs+44μs+44μs*512=22.668ms, that is, the time to send a DMX512 data packet is about 23ms, that is, the preset duration is 23ms.

MCU13 continuously receives the DMX512 signal from the lighting console. After receiving the DMX512 signal, the MTBP bit of the next DMX512 data packet has not been detected after more than 23ms. MCU13 determines that the light emitting element 11 cannot be controlled by the lighting console at this time. That is to determine the DMX512 data packet from presence to absence. Optionally, the MCU 13 sends a blinking signal to make the indicator light on the display panel blink.

In the above-mentioned embodiment, by detecting that no new DMX512 signal sent by the lighting console is received within the preset period of time after receiving the DMX512 signal sent by the lighting console, that is, the DMX512 signal changes from existence to non-existence, to determine whether the lamp cannot be controlled by the lighting console. The control console is used to avoid misoperation if the light bulb is manually turned on and the shutter is opened through the display panel of the MCU.

In one embodiment, the MCU 13 is specifically configured to determine that light from the light emitting element 11 can exit the light fixture when the light emitting element 11 is always on and the shutter of the lamp is opened.

The shutter is the isolation part of the light of the lamp. When the light-emitting element of the lamp is always on and the shutter is opened, the light of the light-emitting element can go out of the lamp. When the light-emitting element of the lamp is always on but the shutter is closed, the light of the light-emitting element Light cannot exit the light fixture.

Optionally, the MCU 13 is specifically configured to determine whether the light emitting element 11 is always on according to the feedback signal from the ballast 12 .

The MCU 13 can communicate with the ballast 12 through the serial port, and the MCU 13 can determine the state of the light emitting element 11 according to the feedback signal of the ballast 12 . For example, when the MCU 13 sends a “ignition” signal to the ballast 12 , the ballast 12 triggers and lights the light emitting element 11 after receiving the signal. When the light-emitting element 11 is successfully lit, the ballast 12 will send a feedback signal of "successfully lit the bubble" to the MCU 13 . Optionally, when the light-emitting element 11 is successfully turned on, the display panel of the MCU 13 may display a corresponding mark for indicating that the light is turned on normally. When the light-emitting element 11 is turned off abnormally, the ballast 12 will send a feedback signal of "the bulb is abnormal" to the MCU 13 . Therefore, when the light-emitting element 11 is turned on, if the MCU 13 has not received the feedback signal of "abnormal light bulb" from the ballast 12, it can determine that the light-emitting element 11 is always on.

In the embodiment of the present application, the MCU 13 is specifically used to determine the state of the shutter of the lamp according to the address code of the lamp, the model of the lamp and the DMX512 signal.

The lighting console continuously sends DMX512 data packets to all lamps, and the lamp MCU saves the received DMX512 data packets in the cache, and the lamps perform corresponding functions according to the DMX512 data packets in the cache. The DMX512 data packets in the buffer are continuously updated. When the lamp cannot be controlled by the lighting console, that is, the MCU13 does not receive a new DMX512 data packet, the shutter of the lamp is determined according to the last received DMX512 data packet in the buffer. state.

The lighting console can communicate with the lamps through the DMX512 signal line. The same DMX512 signal line can connect multiple lamps. Different lamps are distinguished by different address codes and channel numbers. 1 address code corresponds to 1 data frame, a DMX512 data packet has 512 data frames in total, and the faulty lamp only needs to capture the corresponding DMX512 data frame. A data frame includes 1 low-level start bit, 8 data bits, and 2 high-level stop bits. The 8 data bits are the control channel value 0-255, as shown in Figure 3.

For example, the number of channels of the lamp is 30, and the address code is 31, that is, the MCU13 of the lamp only obtains the 31st-60th DMX512 data frames. The faulty lamp MCU13 first inquires about the model of the built-in lamp and the channel level value of the shutter channel. For example, the lamp model of the faulty lamp is 550BSW, and the 11th channel is the shutter channel. Since the address code set by the faulty lamp is 31, the 42nd (31+11=42) DMX512 data frame corresponds to the shutter channel. The 8 data bits in the data frame are all 1, that is, the optical gate channel level value is 255, and the optical gate is opened at this time. The MCU13 determines that the shutter of the lamp is opened through the received channel level value.

Optionally, MCU13 is specifically used to send a control signal to Ballast 12.

The preset time threshold is the timing threshold of the emergency system. If the DMX512 signal is not received beyond the preset time threshold, the control signal will be sent to the ballast. If the DMX512 signal is received before the preset time threshold, it means this When the lamp can be controlled by the lighting console, no control signal is sent to the ballast to turn off the bulb. Optionally, take the lamp as an example of a halogen bulb beam lamp. The timing threshold of the halogen bulb beam emergency system is 3 minutes. When the signal line is disconnected and then connected again, the emergency system will stop timing, and the lamps will continue to receive DMX512 data packets normally.

In one embodiment, as shown in FIG. 4 , the lamp further includes a wireless receiving module 41 for the MCU 13 to receive DMX512 signals wirelessly.

Optionally, the lamps can also communicate with the lighting console through a wireless connection. The lamp includes a wireless receiving module 41, and the MCU13 receives the DMX512 signal of the lighting console through wireless.

When the lamp is set to the wireless DMX512 receiving mode, the wireless receiving module 41 sends a link signal to the MCU13, and the MCU13 receives the link signal and performs matching. If the matching is successful, the DMX512 signal can be received wirelessly. If MCU13 does not detect the wireless DMX512 link signal, even if the lighting console sends wireless DMX512 data packets, MCU13 cannot receive the DMX512 data packets.

Optionally, the lamp also includes a network cable, which is used for the MCU13 to receive DMX512 signals through the network cable.

In large-scale performance scenes, more and more lamps are used. Optionally, the lamps can also receive DMX512 data packets through the network cable. When the lamps are connected to the network cable and set to Art-Net receiving mode, the detection of the port address is added. , used to judge the reception of DMX512 data packets.

Art-Net is a 10base T Ethernet protocol based on TCP/IP protocol, which can allow a large number of DMX512 data frames to be transmitted to devices in the domain, and the maximum output speed can reach 10M/S. Therefore, the lamp needs to set the IP address first, for example: 255.0.0.0. Art-Net also includes a port address (Port-Address), the port address is 15 digits, including Net (network) + Sub-Net (subnet) + Universe (packet), the port address of the lamp Art-Net is as follows Figure 5 shows.

Among them, there are 32768 (2 ¹⁵ = 32768) port addresses in total, and the network group number is composed of Net (network) + Sub-Net (subnet), and there are 128 (2 ⁷ = 128) in total. 256 (2 ⁸ =256) pieces. A DMX512 data packet consists of 1 MTBP bit, 1 Break bit, 1 MAB, 1 SC and 512 data frames. 1 data frame contains 1 low-level start bit, 8 data bits, and 2 high-level stop bits, among which 8 data bits are the control channel value 0-255. 1 data frame corresponds to 1 address code , a total of 512 address codes.

Each port address can write controllable DMX512 data frames, and these data frames are placed in the port address in the form of data packets. Therefore, the lamp also needs to set the network group number, which can be 1-128, and the address code, which can be 1-512. Then the lamp also needs to set the network group number and address code. After completing the above settings, the lamps can normally receive the DMX512 data packets sent by the lighting console through the network cable. If MCU13 does not detect the port address of the lamp Art-Net, including the network group number and address code of the lamp, even if the lighting console sends DMX512 data packets remotely, the lamp MCU13 cannot receive the DMX512 data packets on the network cable.

In the above-mentioned embodiments, in addition to the communication mode of DMX512 signal line connection commonly used by stage lamps, the lamps can also communicate through wireless connection and network cable connection, and control the lamps can be realized.

In the second aspect, the present application also provides a lamp control method, as shown in FIG. 6, the method includes:

Step 601, when it is determined that the light fixture cannot be controlled by the lighting console, and the light of the light fixture can exit the light fixture.

Among them, as mentioned above, the lamp MCU determines that the lamp cannot be controlled by the lighting console, and the light of the lamp can exit the lamp. Lights are turned off.

Step 602, sending a control signal to control the light-emitting element of the lamp to turn off through the ballast arranged inside the lamp.

The MCU of the lamp sends a control signal to turn off the bulb to the ballast inside the lamp, and the ballast controls the light-emitting element of the lamp to turn off, and at the same time, the ballast feeds back a signal of "successful defoaming" to the MCU, and the MCU determines that the lamp has been successfully extinguished.

In one embodiment, determining that the lamp cannot be controlled by the lighting console includes: regularly receiving the DMX512 signal sent by the lighting console, and if the DMX512 signal is not received after a preset period of time, then determining that the lamp cannot be controlled by the lighting console .

The lamp MCU regularly receives the DMX512 signal sent by the lighting console. The preset duration is the transmission time of one DMX512 data packet as described in the above embodiment. When the preset duration is exceeded, that is, the transmission time of one DMX512 data packet is still When a new DMX512 signal is received, it is determined that the lamp cannot be controlled by the lighting console at this time.

Optionally, the step of determining that the light of the luminaire can exit the luminaire, as shown in Figure 7, includes:

Step 701, receiving a feedback signal from a ballast.

As described in the above embodiments, after the lamp MCU sends a control signal to the ballast, the ballast controls the light-emitting element to perform corresponding actions, and then sends a feedback signal to the MCU.

Step 702, determine whether the light emitting element is always on according to the feedback signal.

If the MCU of the lamp sends a "light up" signal to the ballast, the ballast triggers and lights up the light-emitting element. When the light-emitting element is successfully lit, the ballast sends a "successfully light up" signal to the MCU. Since then, if the MCU has not received other feedback signals from the ballast, such as "the bulb is abnormal", the MCU determines that the light-emitting element is always on.

Step 703, according to the address code of the lamp, the model of the lamp and the DMX512 signal, determine the state of the shutter of the lamp.

The specific steps of determining the state of the shutter of the lamp are as described in the embodiments of the lamp above.

Step 704, according to whether the light-emitting element is always on and the state of the shutter, it is determined whether the light of the lamp can exit the lamp.

When the light-emitting element is always on and the shutter is open, it is determined that the light of the lamp can exit the lamp. If any of the above two conditions is not met, it is determined that the light of the lamp cannot exit the lamp.

In one embodiment, when the lamp communicates with the lighting console through a DMX512 signal line connection, the flow chart of the lamp control method is shown in Figure 8, and the steps include:

(1) The MCU of the lamp detects the MTBP bit of the DMX512 data packet cyclically. If it is detected, it will continue to receive normally. If it is not detected, it will perform step 2.
