It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

The embodiment of the present disclosure provides an illumination control device, and fig. 1 is a schematic structural diagram of an illumination control device provided in the embodiment of the present disclosure. As shown in fig. 1, the lighting control device includes: the strobe module 10, and the power source interface 20, the first fixture interface 30 and the second fixture interface 40 electrically connected to the strobe module 10.

The power interface 20 is configured to receive a first driving signal, the first lamp interface 30 is configured to electrically connect to the first lamp 31, the second lamp interface 40 includes a second lamp connection end 42 and a power end 41, the second lamp connection end 42 is configured to connect to the second lamp 43, and the power end 41 is configured to connect to an external power source 44.

The gating module 10 switches on the power source terminal 41 and the second lamp connecting terminal 42 according to the first driving signal, and/or switches on the power source interface 20 and the first lamp interface 30.

Specifically, the gating module 10 is electrically connected to the power interface 20, and receives a first driving signal, which is transmitted to the gating module 10 through the power interface 20. When the first driving signal is a signal for driving the first lamp 31 to emit light, the gating module 10 may turn on the first lamp interface 30 and the power interface 20 according to the first driving signal, at this time, the first lamp 31 may obtain a current transmitted by the power interface 20, and the first lamp 31 is started to play a role in lighting.

The power terminal 41 of the second lamp interface 40 is electrically connected to the external power source 44, and is powered by the external power source 44, and the second lamp connection terminal 42 may be electrically connected to the second lamp 43. When the first driving signal is a signal for driving the second lamp 43 to emit light, the gating module 10 switches on the power terminal 41 and the second lamp connecting terminal 42, at this time, the second lamp 43 can obtain the current sequentially transmitted by the external power source 44 through the power terminal 41 and the second lamp connecting terminal 42, and the second lamp 43 is started to play a role in lighting.

When the first driving signal is a signal for driving the first lamp 31 and the second lamp 43 to start jointly, the gating module 10 switches on the first lamp interface 30 and the power interface 20, and switches on the power terminal 41 and the second lamp connection terminal 42 according to the first driving signal. At this time, the first lamp 31 may obtain the current transmitted by the power interface 20, and the first lamp 31 is started; the second lamp 43 can obtain the current sequentially transmitted by the external power source 44 through the power source end 41 and the second lamp connecting end 42, the second lamp 43 is started, and the first lamp 31 and the second lamp 43 jointly play a role in illumination.

In the embodiment of the present disclosure, the gating module 10 may control different circuits to be turned on according to the first driving signal received by the power interface 20, so as to control the lamps corresponding to the conducting portions to emit light. Illustratively, the luminances of the respective luminaires may be different, for example, the luminance of the second luminaire 43 is greater than the luminance of the first luminaire 31. When a darker light is required, the first driving signal is only required to be a signal for controlling the first lamp 31, and at this time, the first lamp 31 is started under the control of the first driving signal, and the second lamp 43 is not started. When brighter light is required, the first driving signal is only required to be the signal for controlling the second lamp 43, at this time, the second lamp 43 is started under the control of the first driving signal, and the first lamp 31 is not started. When brighter light is required, the two lamps can be started simultaneously, so that the first driving signal is a signal for simultaneously controlling the first lamp 31 and the second lamp 43, at this time, the two lamps are started simultaneously under the control of the first driving signal, and the brightness of the light is enhanced. When a plurality of lamps are needed to be started, each lamp does not need to be controlled independently, the plurality of lamps can be controlled simultaneously through the first driving signal, and proper light brightness is selected.

The gating module in the embodiment of the disclosure receives the first driving signal through the power interface, and then can switch on the power interface and the first lamp interface according to the first driving signal, and/or switch on the power end and the second lamp connecting end, thereby controlling the first lamp and/or the second lamp to be turned on. If the gating module conducts the first lamp interface and the power supply interface according to the first driving signal, the first lamp emits light at the moment, and the lighting function is achieved; the first lamp interface and the power interface are conducted according to the first driving signal, the power end and the second lamp connecting end are also conducted, then the first lamp and the second lamp emit light, and the two lamps play a role in illumination under the control of the same driving signal. Different lamps can be started according to the brightness requirement required by a user, the plurality of lamps can be controlled to be started or closed simultaneously, the switches of the lamps are not required to be controlled independently, the user can control the lamps more conveniently, and the user does not need to walk to the switches of the lamps to operate respectively.

In some embodiments, fig. 2 is a schematic structural diagram of another lighting control device provided by the embodiments of the present disclosure, and referring to fig. 2, the gating module 10 includes a first relay 11 including a first coil 111 and a first normally open contact 112.

The power interface 20 includes a negative power interface 22 and a positive power interface 21, and the first coil 111 is connected in series between the negative power interface 22 and the positive power interface 21 of the power interface 20.

The first lamp interface 30 includes a first lamp positive power interface 301 and a first lamp negative power interface 302, the first lamp positive power interface 301 is electrically connected to the positive power interface 21, and the first lamp negative power interface 302 is electrically connected to the negative power interface 22.

The second lamp connecting terminal 42 is electrically connected to the first contact 1121 of the first normally open contact 112, and the power terminal 41 is electrically connected to the second contact 1122 of the first normally open contact 112.

Specifically, two ends of the first coil 111 in the first relay 11 are electrically connected to the positive power interface 21 and the negative power interface 22 of the power interface 20, respectively, to form a loop, and the first normally-open contact 112 in the first relay 11 is disposed between the power end 41 and the second lamp connection end 42.

Illustratively, the first driving signal is a current, and when the current is small and does not reach the pull-in current of the first relay 11, the power source terminal 41 and the second lamp connecting terminal 42 cannot be connected, and at this time, the current can only flow through the first lamp interface 30 through the power source interface 20, so as to supply power to the first lamp 31, and start it. When the current is larger, but still does not reach the pull-in current of the first relay 11, the power end 41 and the second lamp connection end 42 cannot be conducted, at this time, the current can only flow through the first lamp interface 30 through the power interface 20, and then the first lamp 31 is powered on, so that the first lamp is started, and the first lamp becomes brighter as the current becomes larger, so that the brightness of the first lamp can be adjusted.

When the current of the first driving signal is larger, the requirement of the pull-in current of the first relay 11 is met, the first normally open contact 112 is closed, the power end 41 is connected to the second lamp connection end 42, and at this time, the external power source 44 supplies power to the second lamp 43 through the power end 41 and the second lamp connection end 42, so that the second lamp 43 can be started. The current received by the power interface 20 can control the first lamp 31 to start at the same time when the first relay 11 is attracted, because the current is large at this time, the brightness of the first lamp 31 is brighter, and the first lamp 31 and the second lamp 43 are started at the same time to jointly illuminate, so that the overall brightness is improved.

In the embodiment of the disclosure, the gating module receives the first driving signal through the power interface, and then can switch on the power interface and the first lamp interface according to the first driving signal, and/or switch on the power end and the second lamp connecting end, thereby controlling the first lamp and/or the second lamp to be turned on. The two lamps execute corresponding functions under the control of the same driving signal. Different lamps can be started according to the brightness requirement required by a user, the plurality of lamps can be controlled to be started or closed simultaneously, the switches of the lamps are not required to be controlled independently, the user can control the lamps more conveniently, and the user does not need to walk to the switches of the lamps to operate respectively.

It should be noted that, because the first normally open contact of the first relay is arranged at the connection end of the power supply end and the second lamp, the external power supply can be other power supply devices, and can also be a live wire of a mains supply, and is selected according to actual requirements.

In some embodiments, fig. 3 is a schematic structural diagram of another lighting control device provided by the embodiments of the present disclosure, and as shown in fig. 3, the gating module further includes a second relay 12, and the second relay 12 includes a second normally-open contact 122 and a second coil 121.

The second coil 121 is connected in series between the negative power interface 22 and the positive power interface 21 of the power interface 20, the first lamp positive power interface 301 is electrically connected to the positive power interface 21 through the second normally open contact 122, the first lamp positive power interface 301 is electrically connected to the fourth contact 1222 of the second normally open contact 122, the positive power interface 21 is electrically connected to the third contact 1221 of the second normally open contact 122, and the pull-in current of the second relay 12 is smaller than the pull-in current of the first relay 11.

Specifically, two ends of the second coil 121 in the gating module are electrically connected to the positive power interface 21 and the negative power interface 22, respectively, the second normally-open contact 122 is disposed between the first fixture positive power interface 301 and the positive power interface 21, the first fixture positive power interface 301 is electrically connected to the fourth contact 1222, and the positive power interface 21 is electrically connected to the third contact 1221. If the second normally open contact 122 is closed by the first driving signal, the first lamp 31 is started to play a role of illumination. If the first driving signal can also close the first normally-open contact 112, the gating module 10 turns on the power source terminal 41 and the second lamp connecting terminal 42, and at this time, the second lamp 43 can obtain the current of the external power source 44, and the second lamp 43 is started to play a role in lighting through the currents sequentially transmitted by the power source terminal 41 and the second lamp connecting terminal 42.

Illustratively, when the power interface 20 receives the first driving signal, the first driving signal is a current. When the received current is a small current, the pull-in current of the second relay 12 is satisfied, but the pull-in current of the first relay 11 is not reached, the current flowing out from the positive power supply interface 21 passes through the first coil 111, the first normally open contact 112 cannot be closed, the second lamp 43 cannot be started, the current reaches the second coil 121 through the first coil 111, the current satisfies the pull-in current of the second relay 12, the second normally open contact 122 is closed, and the current flows back to the negative power supply interface 22. After the second normally open contact 122 is closed, the current flows from the positive power interface 21 through the second normally open contact 122 and the first lamp interface 30, and then the first lamp 31 is controlled to start.

When the received current increases, but still only satisfies the pull-in current of the second relay 12, but does not reach the pull-in current of the first relay 11, the first relay 11 cannot pull in, the second lamp 43 is in a closed state, and the first relay 11 pulls in, and the first lamp is started under the action of the current. As the current received by the first lamp 31 becomes larger, the brightness also increases, so that the brightness of the first lamp 31 can be controlled.

When the received current continues to increase, the current is a large current at this time, which satisfies the pull-in current of the second relay 12 and the pull-in current of the first relay 11, and the current flowing out from the positive power interface 21 passes through the first coil 111, so that the first normally open contact 112 is closed, the second lamp connection end 42 and the power supply end 41 are conducted, and the second lamp 43 is controlled to start. The current continues to reach the second coil 121 through the first coil 111, the current meets the pull-in current of the second relay 12, the second normally open contact 122 is closed, and the current flows back to the negative power interface 22. After the second normally open contact 122 of the second relay 12 is closed, the current flows through the second normally open contact 122 and the first lamp interface 30 from the positive power interface 21, so that the first lamp 31 is controlled to be started, and the first lamp 31 and the second lamp 43 illuminate together, thereby meeting the requirement of higher brightness.

If the gating signal sent by the gating signal interface 23 is at a high level, the first transistor 13 is in an off state, the second transistor 14 is turned on, the first relay 11 cannot be attracted, no current flows into the second lamp 43, the second lamp 43 is in an off state, the second transistor 14 is turned on, the second relay 12 is attracted, the second coil 121 is energized, the second normally-open contact 122 is closed, the current can flow through the first lamp positive power supply interface 301, the first lamp 31 receives the current to form a loop, and the first lamp 31 is started.

If the first transistor 13 is of the N-type and the second transistor 14 is of the P-type, the control method is similar to the above embodiment. When the first transistor 13 is N-type, the second transistor 14 is P-type, if the gating signal sent by the gating signal interface 23 is high level, the first transistor 13 is turned on, the second transistor 14 is not turned on, the first relay 11 is attracted, the first coil 111 receives a current signal from the positive power supply interface 21, the first normally open contact 112 is closed, the second lamp 43 is started, the second transistor 14 is not turned on, the second relay 12 is not attracted, no current flows into the first lamp 31, and the first lamp 31 is off.

According to the embodiment of the disclosure, different driving signals are selectively sent according to different driving signals of different transistors, so that different lamps are started, and various brightness requirements of users are met.

If the signal is a low level signal, the first transistor 13 is turned on, the first lamp 31 is turned on, the second transistor 14 is turned off, and the second lamp 43 is turned off, so that only the first lamp 31 is controlled to emit light. When the first transistor 13 is an N-type transistor and the second transistor 14 is a P-type transistor, if the signal sent by the gating signal interface 23 is a low level signal, the second transistor 14 is turned on, the second lamp 43 is turned on, the first transistor 13 is not turned on, the first lamp 31 is not turned on, and at this time, only the second lamp 43 is controlled to emit light. If the gating signal interface 23 sends a high level signal, the first transistor 13 is turned on, the first lamp 31 is started, the second transistor 14 is not turned on, and the second lamp 43 is not started, so that only the first lamp 31 is controlled to emit light.
