Description

Technical Field

[0001] This invention relates to the field of architectural lighting technology, specifically a lighting control system with dual operating modes. Background Technology

[0002] In the field of architectural lighting technology, lighting control solutions for public areas need to balance energy efficiency, safety, and flexibility. Current mainstream control technologies mainly include traditional rocker switch control, sensor control, and intelligent centralized lighting control systems; however, these solutions still have significant shortcomings in practical applications.

[0003] Traditional rocker switch control, while simple in structure, relies on manual operation and cannot achieve dynamic dimming, leading to significant energy waste and failing to meet current energy-saving standards. While sensor-based control, using radar, infrared, or sound sensing technology to achieve "lights on when people are present, lights off when people leave," effectively reduces energy consumption but suffers from sudden lighting changes. For example, in areas where minors play or in hospital corridors, sudden lighting failure could pose a fall risk, failing to meet the safety requirements for lighting in special locations outlined in GB55015-2021, the General Code for Building Energy Conservation and Renewable Energy Utilization. Furthermore, single-sensor control is susceptible to environmental interference (such as false triggering or missed detection), resulting in low reliability. Meanwhile, existing intelligent centralized lighting control systems, which achieve zoned dimming or timed control through a central controller, balance energy saving and safety requirements, but their complex architecture necessitates additional communication modules and control terminals, leading to high project costs. Moreover, such systems have fixed control logic, limiting their adaptability and inability to flexibly adjust operating modes according to different time periods or scenarios.

[0004] Therefore, there is an urgent need in the field for a lighting control system with dual operating modes to solve the above problems. Summary of the Invention

[0030] Example 1

[0031] like Figure 1 As shown, this embodiment provides a lighting control system with dual working modes, including a lighting control circuit and a power supply switching circuit;

[0032] For example, the lighting control circuit includes a time-delay switch 4, an LED driver 5, an LED lamp 6, a first live wire terminal 2, a second live wire terminal 3, and a neutral wire terminal 11; the power supply switching circuit includes a circuit breaker 1, a contactor, and a time controller.

[0033] Specifically, the input terminal of circuit breaker 1 is electrically connected to the first live wire L, the first output terminal of circuit breaker 1 is electrically connected to the input terminal of the first live wire terminal 2, and the output terminal of the first live wire terminal 2 is electrically connected in sequence to the positive input terminal of the induction delay switch 4 and the LED driver 5.

[0034] The second output terminal of the circuit breaker 1 is electrically connected to the normally open contact 7 of the contactor and the input terminal of the second live wire terminal 3 in sequence. The output terminal of the second live wire terminal 3 is electrically connected to the positive input terminal of the LED driver 5.

[0035] One end of the neutral terminal 11 is electrically connected to the first neutral line N, and the other end is electrically connected to the negative input terminal of the LED driver 5; the positive output terminal of the LED driver 5 is electrically connected to the positive electrode of the LED lamp 6, and the negative output terminal of the LED driver 5 is electrically connected to the negative electrode of the LED lamp 6.

[0036] One end of the normally open contact 8 of the time controller is electrically connected to the second live wire L′, and the other end is electrically connected to the control coil 10 of the contactor and the second neutral wire N′ in sequence. It is used to control the on and off of the contactor within a preset time period so as to close or open the normally open contact 7 of the contactor, thereby realizing the switching of the power supply path.

[0037] In some embodiments, the power switching circuit further includes an emergency signal receiver;

[0038] Specifically, one end of the normally open contact 9 of the emergency signal receiver is electrically connected to the second live wire L′, and the other end is electrically connected to the control coil 10 of the contactor. This is used to control the contactor to open or close after receiving an external emergency signal, thereby switching the power supply path.

[0039] In some embodiments, the power supply switching circuit further includes a fuse;

[0040] One end of the fuse is connected to the second live wire L′, and the other end of the fuse is connected to the normally open contact 8 of the time controller and the normally open contact 9 of the emergency signal receiver.

[0041] In some embodiments, the lighting control circuit also includes a ground PE terminal 12;

[0042] One end of the ground wire PE terminal 12 is electrically connected to the ground terminal of the LED driver 5, and the other end is electrically connected to the ground wire PE.

[0043] In some embodiments, the first live wire L, the second live wire L′, the first neutral wire N, the second neutral wire N′, and the ground wire PE are electrically connected to the distribution box busbar 14, respectively.

[0044] In some embodiments, external emergency signals include, but are not limited to, fire emergency signals, disaster warning signals, security alarm signals, and medical emergency signals.

[0045] In some embodiments, the induction delay switch 4 includes any one of a radar induction delay switch 4, a human body induction delay switch 4, or a sound induction delay switch 4;

[0046] The induction delay switch 4 is normally in the off state. When a person or object passes through the preset range of the induction delay switch 4, the induction delay switch 4 is turned on to turn on the light. After the light is turned on, the induction delay switch 4 will turn off if no person or object passes through in the meantime, and the light will turn off. If a person or object passes through in the meantime, the time when the person or object passes through in the meantime will be used as the starting point to start the timer again according to the timer, and so on.

[0047] In this embodiment, the circuit breaker 1 is sequentially connected to the first live wire terminal 2, the induction delay switch 4 and the LED driver 5 to form an induction working mode, so as to realize the induction control of the lamp on and off and the delayed shutdown by controlling the lamp through the induction delay switch 4.

[0048] The normally open contact 8 of the time controller or the normally open contact 9 of the emergency signal receiver is electrically connected to the control coil 10 of the contactor. The circuit breaker 1 is then connected in sequence to the normally open contact 7 of the contactor, the second live wire terminal 3, and the LED driver 5, forming a constant-on working mode. This allows the light fixture to remain on within a set time period or in an emergency. Within the set time period, the normally open contact 8 of the time controller closes, energizing the control coil 10 of the contactor, which in turn controls the normally open contact 7 of the contactor to close, connecting the circuit and keeping the light fixture on. Upon receiving an external emergency signal, the emergency signal receiver activates, closing its normally open contact 9, which in turn energizes the control coil 10 of the contactor, controlling the normally open contact 7 of the contactor to close, connecting the circuit and keeping the light fixture on.

[0049] This embodiment simplifies the lighting control circuit architecture, reduces the complexity of the lighting control system, and enables independent operation in two modes without relying on high-cost intelligent control modules. This significantly reduces equipment procurement and subsequent maintenance costs, making it significantly more economical than traditional intelligent lighting systems. It can be widely applied to lighting systems in various types of buildings.

[0050] In this embodiment, the lighting control system can be used in public areas without natural lighting inside buildings such as schools, hospitals, senior apartments, office buildings, and shopping malls (e.g., stairwells, restrooms, elevator lobbies, underground parking garages, etc. in schools / hospitals / senior apartments). The constant-on mode of the lighting control system can be used in high-traffic periods in these areas (e.g., during school hours, or during working hours in hospitals, senior apartments, office buildings, and shopping malls) or in emergency situations (fire emergencies, disaster warnings, security alarms, and medical emergencies). The sensor-activated mode of the lighting control system can be used in low-traffic periods in these areas (e.g., during holidays or after school, or late nights in hospitals, senior apartments, office buildings, and shopping malls). Furthermore, the parking garage lighting for different types of buildings, such as residential buildings, shopping malls, and hospitals, can be controlled according to the traffic characteristics of the parking garage at different times, using a constant-on mode during high-traffic periods and a sensor-activated mode during low-traffic periods.

[0051] Example 2

[0052] like Figure 2 As shown, this embodiment provides a lighting control system with dual working modes. The difference between this embodiment and embodiment 1 is that the lighting control circuit also includes a light control switch 13.

[0053] Specifically, the input terminal of the light control switch 13 is electrically connected to the output terminal of the induction delay switch 4 and the second live wire terminal 3, respectively, and the output terminal of the light control switch 13 is electrically connected to the positive input terminal of the LED driver 5.

[0054] In some embodiments, the light control switch 13 is an infrared light control switch 13. Since the infrared light content of the LED lamp 6 is relatively low, the interference of the LED lamp 6's own light on the light control detection is effectively avoided, thus avoiding the problem of false triggering of the light control switch 13.

[0055] In this embodiment, the circuit breaker 1 is sequentially connected to the first live wire terminal 2, the induction delay switch 4, the light control switch 13 and the positive input terminal of the LED driver 5 to form an induction + light control working mode, so as to realize the coordinated action of the induction delay switch 4 and the light control switch 13 to trigger the light-up when the ambient light is insufficient and human activity is detected.

[0056] The normally open contact 8 of the time controller is electrically connected to the control coil 10 of the contactor. The normally open contact 7 of the contactor, the second live wire terminal 3, the light control switch 13 and the LED driver 5 are electrically connected in sequence through the circuit breaker 1 to form a light control working mode, so as to trigger the lighting when the ambient light is insufficient within a set time period.

[0057] In this embodiment, the problem that traditional single-mode lamps cannot adapt to complex scene requirements is solved by using dual live wire L terminals and power supply switching circuit. By selectively conducting the first live wire terminal 2 or the second live wire terminal 3 through the power supply switching circuit, interference-free switching between the sensing + light control working mode and the light control working mode is realized. The human body sensing linkage delayed lamp-off function can be enabled during periods of less human activity, while the pure light control energy-saving mode can be enabled during periods of frequent activity.

[0058] In this embodiment, the light is triggered when the ambient light is insufficient and human activity is detected through the coordinated action of the induction delay switch 4 and the light control switch 13. The dual condition judgment effectively reduces the probability of false operation, extends the service life of the lamp, significantly reduces the energy consumption of the lamp, and improves the comfort of the user experience.

[0059] This embodiment combines emergency signal and time controller control to automatically switch to light control mode in emergency situations, ensuring the safety of evacuation route lighting while also taking into account daily energy-saving needs, and fully meeting the lighting safety requirements for special locations in standards such as GB55015-2021.

[0060] In this embodiment, the lighting control system can be used in public areas with natural lighting inside buildings such as schools, hospitals, senior apartments, office buildings, and shopping malls (e.g., stairwells, restrooms, elevator lobbies, etc. in schools / hospitals / senior apartments). The light control mode of the lighting control system can be used during high-traffic periods in these areas (e.g., during school hours, or during working hours in hospitals, senior apartments, office buildings, and shopping malls) or in emergency situations (fire emergencies, disaster warnings, security alarms, and medical emergencies). The sensor + light control mode of the lighting control system can be used during low-traffic periods in these areas (e.g., during holidays or after school, or late at night in hospitals, senior apartments, office buildings, and shopping malls).

[0061] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, including the combination of various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
