Description
Technical Field
[0001] This application relates to the field of staircase lighting technology, and in particular to a staircase lighting circuit and a staircase light. Background Technology
[0002] Staircase lights, as common lighting devices, are widely used in stairwells and corridors to provide necessary illumination for people's nighttime activities. Common motion-sensor staircase lighting systems typically rely on high-voltage power and use a main control circuit board to manage multiple light panels distributed across different floors. While this design meets basic safety lighting needs to a certain extent, it also has some drawbacks.
[0003] Since each light panel needs to be connected to the main control circuit board via an independent control line, the main control chip must have a sufficient number of pins to support multi-port communication. As the number of light panels increases, the wiring complexity also rises, increasing installation difficulty and affecting the overall aesthetics of the stairwell lights. Furthermore, to ensure orderly lighting when users go up and down the stairs, the light panels on each floor must be connected in a specific order; if a light panel on a particular floor is damaged, the sequential lighting function may not be possible.

[0025] The lighting control circuit is also used to switch to the corresponding full-brightness mode / sequential lighting mode according to the mode switching command;
[0026] In full-brightness mode, the lighting control circuit is used to send the human body sensing information to the remaining lighting control circuits to achieve synchronous lighting of multiple lighting components;
[0027] In the sequential lighting mode, the lighting control circuit is used to send the human body sensing information with the coded sequence number information to the remaining lighting control circuits, so as to enable multiple lighting components to light up sequentially according to the preset parameters.
[0028] In one embodiment, the encoding circuit includes:
[0029] The third trigger circuit is used to output a corresponding third trigger signal when triggered by the user.
[0030] A third wireless communication and control circuit is electrically connected to the third trigger circuit, and is also used to wirelessly connect to the lighting control circuit; the third wireless communication and control circuit is used to send a corresponding coded sequence number according to the third trigger signal.

[0039] This application's technical solution employs a staircase light circuit, which includes multiple lighting components. The staircase light circuit includes multiple light control circuits, a remote control circuit, and an encoding circuit. Each lighting component is equipped with a corresponding light control circuit. The light control circuits are assigned encoding sequence numbers in ascending or descending order and are set with preset parameters such as sequential lighting speed and lighting delay time. When there are few floors, all light control circuits can be directly and wirelessly connected to each other; when there are many floors, each light control circuit is wirelessly connected to at least the light control circuit directly adjacent to its encoding sequence number, forming a complete communication link. When a light control circuit on any floor detects human activity in the surrounding environment, it controls the corresponding lighting component to light up and sends human body detection information with its own encoding sequence number to other associated light control circuits. The next light control circuit that receives the human body detection information lights up its lighting component after a preset first time interval and continues to transmit information to the next light control circuit, and so on, achieving a sequential lighting effect from bottom to top or from top to bottom. All lit lighting components will remain lit for a set extension time, ensuring that users have sufficient light to safely ascend and descend the stairs. If human activity is detected again during this period, the timer can be reset to extend the lighting time. Once the set lighting delay time has elapsed and no new activity is detected, the lighting components will sequentially turn off, returning to the initial state. Users can adjust preset parameters such as the sequential lighting speed and lighting extension time via remote control circuitry to suit different usage needs. Similarly, users can adjust the coding sequence of the lighting control circuits via coding circuitry, for example, re-coding when a lighting control circuit is damaged or replaced. Thus, this application solves the problems of complex wiring and proneness to errors in sequential lighting in existing stairwell lights. Attached Figure Description

[0060] In existing stairwell lights, each light panel needs to be connected to the main control circuit board via an independent control line. This requires the main control chip to have a sufficient number of pins to support multi-port communication. As the number of light panels increases, the wiring complexity also increases, which not only increases the installation difficulty but also affects the overall aesthetics of the stairwell lights. Moreover, in order to ensure that users can achieve an orderly lighting effect when going up and down the stairs, the light panels on each floor must be connected in a specific order. If a light panel on a certain floor is damaged, the sequential lighting function may not be possible.
[0061] This application proposes a staircase light circuit.
[0062] Please see Figure 1 In one embodiment of this application, the stair light includes multiple lighting components, and the stair light circuit includes multiple lighting control circuits 01, remote control circuits 02, and encoding circuits 03.
[0063] Multiple lighting control circuits 01 are connected one-to-one with multiple lighting components; the multiple lighting control circuits 01 are sequentially set with corresponding code numbers in ascending / descending order, and preset lighting parameters are set; wherein, each lighting control circuit 01 is wirelessly connected to at least one lighting control circuit 01 whose code number is directly adjacent to its own.
[0064] The lighting control circuit 01 is used to detect human information in the surrounding environment. When it is determined that there is a human in the surrounding environment, it controls the corresponding lighting component to turn on and sends human sensing information with coded sequence number information to the remaining lighting control circuits 01, so as to realize that multiple lighting components turn on in sequence according to preset parameters. The preset parameters include sequential lighting speed and lighting delay time. The sequential lighting speed is used to indicate the first time interval from the previous lighting component to the next lighting component turning on, and the lighting delay time is used to indicate the second time interval from the lighting component turning on to turning off.
[0065] The remote control circuit 02 is used to wirelessly connect with the lighting control circuit 01. When triggered by the user, the remote control circuit 02 sends a corresponding adjustment command to the lighting control circuit 01 to adjust the preset parameters for lighting.
[0066] The encoding circuit 03 is used to wirelessly connect with the lighting control circuit 01. When triggered by the user, the encoding circuit 03 sends the corresponding encoding sequence number to the lighting control circuit 01 to adjust the encoding sequence number of the lighting control circuit 01.
[0067] It should be noted that when the number of staircases is relatively small, all lighting control circuits 01 can be directly and wirelessly connected to each other. In this fully connected mode, any two lighting control circuits 01 do not need to rely on other intermediate floors for information forwarding, making information transmission more direct and efficient. In scenarios with many floors, to simplify the network structure and ensure communication reliability, each lighting control circuit 01 maintains a wireless connection with at least one lighting control circuit 01 directly adjacent to its coded sequence number. It should be noted that there may be one or two lighting control circuits 01 directly adjacent to each other in coded sequence numbers. For example, if multiple lighting control circuits are assigned corresponding coded sequence numbers in ascending order, then the lighting control circuit 01 with the largest coded sequence number is wirelessly connected to at least the preceding lighting control circuit 01 directly adjacent to its coded sequence number, the lighting control circuit 01 with the smallest coded sequence number is wirelessly connected to at least the following lighting control circuit 01 directly adjacent to its coded sequence number, and the lighting control circuit 01 with an intermediate coded sequence number is wirelessly connected to at least the two lighting control circuits 01 directly adjacent to its coded sequence number. In this way, the previous lighting control circuit 01 and the next lighting control circuit 01 can form a direct communication link. If information needs to be transmitted from one floor to another, it can be forwarded step by step through the lighting control circuit 01 on the intermediate floor, ensuring that the information can reach its destination along the path. In this way, this embodiment can guarantee effective information exchange between the lighting control circuits 01.
[0068] It should be noted that the lighting components may include LED lights, and the lighting control circuit 01 may include a human body sensor for detecting human information in the surrounding environment where the lighting control circuit 01 is located, a wireless communication module for sending / receiving human body sensing information with coded sequence number information, a lighting drive circuit for driving the LED lights, and a controller for controlling the operation of the above circuits. In one embodiment, assuming there are ten floors of stairs, stair lights are installed on the ten floors, and each floor has a lighting component installed, which is controlled by its respective lighting control circuit 01. In this embodiment, ten lighting control circuits 01 can be set up to correspond one-to-one with the lighting components on the ten floors. The ten lighting control circuits 01 are assigned coded sequence numbers in ascending / descending order, for example from 1 to 10, corresponding to the lighting component on each step. The coding circuit 03 is used to set or adjust the coded sequence number to ensure that it can be reordered or adjusted even after the lighting control circuits 01 are installed. In addition, preset parameters for completing the lighting before installation are set in advance, including sequential lighting speed (first time interval) and lighting delay time (second time interval).
[0069] When someone begins to ascend the stairs, the human body sensor in the lowest-level (let's say code number 1) lighting control circuit 01 detects their presence. This circuit immediately illuminates the corresponding LED and sends human body detection information, containing its own code number, to the next (code number 2) lighting control circuit 01. The second lighting control circuit 01 (code number 2), upon receiving the human body detection information, illuminates its LED after a preset first time interval delay and continues wirelessly sending information to the next lighting control circuit 01. This process can be repeated along the increasing code sequence until the human body detection information containing the code number is sent to all remaining lighting control circuits 01, illuminating all the LEDs. All LEDs remain lit for a preset second time interval, providing sufficient time for people to safely ascend and descend the stairs. If any lighting control circuit 01 detects human activity again during this period, it can reset the timer and extend the lighting time. If no further human activity is detected, after the second time interval, multiple LEDs gradually turn off, returning to their initial state and awaiting the next trigger. Thus, this embodiment enables ten LED lights to illuminate sequentially according to a preset lighting speed and delay time. It is understood that if human activity is detected on a middle floor, the LED lights will illuminate sequentially from the middle floor upwards and then to the floors below. If human activity is detected on the top floor, the LED lights will illuminate sequentially from the top floor to the bottom floor. Users can adjust preset parameters via remote control circuit 02, such as changing the lighting speed or delay time, to suit different needs or preferences. Similarly, if the coding sequence number needs adjustment (due to damage or replacement of light control circuit 01), it can be adjusted via coding circuit 03. This embodiment simplifies wiring, and when a light control circuit 01 is damaged or replaced, the coding circuit 03 can re-encode the remaining light control circuits to achieve sequential lighting, solving the problems of complex wiring and error-prone sequential lighting in existing stairwell lights.
[0070] In this application, each lighting component is equipped with a corresponding lighting control circuit 01. The lighting control circuit 01 is assigned a code number in ascending or descending order and is set with preset parameters such as sequential lighting speed and lighting delay time. When there are few floors, all lighting control circuits 01 can be directly and wirelessly connected to each other; when there are many floors, each lighting control circuit 01 is wirelessly connected to at least one lighting control circuit 01 directly adjacent to its code number, forming a complete communication link. When any lighting control circuit 01 on any floor detects human activity in the surrounding environment, it controls the corresponding lighting component to light up and sends human body detection information with its own code number to other associated lighting control circuits 01. The next lighting control circuit 01 that receives the human body detection information lights up its lighting component after a preset first time interval and continues to transmit information to the next lighting control circuit 01, and so on, achieving a sequential lighting effect from bottom to top or from top to bottom. All lit lighting components will remain lit for a set extended time to ensure that users have sufficient light to safely go up and down stairs. If human activity is detected again during this period, the timer can be reset to extend the lighting time. Once the set lighting delay time is exceeded and no new activity is detected, the lighting components will sequentially turn off, returning to their initial state. Users can adjust preset parameters such as the sequential lighting speed and lighting delay time via remote control circuit 02 to suit different usage needs. Similarly, users can adjust the coding sequence number of the lighting control circuit 01 via coding circuit 03, for example, re-coding when a lighting control circuit is damaged or replaced. Thus, this application solves the problems of complex wiring and proneness to errors in sequential lighting in existing stairwell lights.
[0071] In one embodiment of this application, the lighting control circuit 01 is further configured to send an adjustment command to the remaining lighting control circuits 01 when an adjustment command is received, so as to realize the synchronous adjustment of the preset parameters of the multiple lighting control circuits 01.
[0072] In this embodiment, each lighting control circuit 01 receives and forwards adjustment commands, allowing the entire staircase lighting setup to be updated quickly and consistently. Users do not need to access each lighting control circuit 01 for individual settings; they only need to initiate an operation via the remote control circuit 02 to adjust the preset parameters of the entire staircase lighting control circuit 01. Thus, even in multi-story buildings, users can easily adjust the operation of multiple lighting control circuits 01, reducing their operational burden and improving the usability of the staircase lighting.
[0073] Please see Figures 2 to 8 In one embodiment of this application, the lighting control circuit 01 includes:
[0074] Lighting drive circuit, which is connected to the corresponding lighting component;
[0075] Storage circuit, used to store the encoding sequence number and preset parameters;
[0076] The human body sensing circuit is used to detect the infrared information of the human body in the surrounding environment where the lighting control circuit 01 is located, and send the corresponding infrared sensing signal.
[0077] The first wireless communication and control circuit is electrically connected to the signal interaction terminal of the storage circuit, the signal input terminal of the lighting drive circuit, and the signal output terminal of the human body sensing circuit. The first wireless communication and control circuit is used to receive infrared sensing signals. When it is determined that there is a human body in the surrounding environment based on the infrared sensing signals, it controls the lighting drive circuit to drive the corresponding lighting component to turn on. Based on the infrared sensing signals and the coded sequence number, it sends human body sensing information with coded sequence number information to the first wireless communication and control circuit of the remaining lighting control circuit 01, so as to realize that multiple lighting components turn on in sequence according to preset parameters.
[0078] The lighting control circuit 01 also includes:
[0079] The light intensity detection circuit is connected to the first wireless communication and control circuit. The light intensity detection circuit is used to detect the light intensity information of the surrounding environment where the light control circuit 01 is located, and output the corresponding light intensity detection signal.
[0080] The first wireless communication and control circuit is also used to control the operation of the lighting drive circuit based on the light intensity detection signal.
[0081] In one feasible implementation, please refer to Figure 4 The human body sensing circuit may include capacitor C131, an infrared probe PIR, and an infrared detection chip U3. The infrared probe PIR can be a D220AX sensor, responsible for receiving changes in human infrared radiation from the surrounding environment and transmitting these changes as electrical signals to the infrared detection chip U3. The infrared detection chip U3 can be an AS159A-8A chip, which, after receiving the electrical signal from the infrared probe PIR, performs amplification, filtering, and analog-to-digital conversion to convert it into an infrared sensing signal, which is then sent to the first wireless communication and control circuit.
[0082] In one feasible implementation, please refer to Figure 5 The lighting components include a cool light lamp (LC) and a warm light lamp (LW); the lighting driving circuit includes a cool light lamp driving circuit and a warm light lamp driving circuit; the cool light lamp driving circuit includes a first resistor R141, a second resistor R142 and a first switch Q141; the warm light lamp driving circuit includes a third resistor R143, a fourth resistor R144 and a second switch Q142.
[0083] One end of the first resistor R141 is connected to the first PWM signal output terminal of the first wireless communication and control circuit. The other end of the first resistor R141 and one end of the second resistor R142 are connected to the controlled terminal of the first switching transistor Q141. The other end of the second resistor R142 is grounded to the first terminal of the first switching transistor Q141. The second terminal of the first switching transistor Q141 is connected to the first power supply terminal of the fluorescent lamp LC. The second power supply terminal of the fluorescent lamp LC is connected to the power supply terminal of the fluorescent lamp driving circuit.
[0084] One end of the third resistor R143 is connected to the second PWM signal output terminal of the first wireless communication and control circuit. The other end of the third resistor R143 and one end of the fourth resistor R144 are connected to the controlled terminal of the second switch Q142. The other end of the fourth resistor R144 is grounded to the first terminal of the second switch Q142. The second terminal of the second switch Q142 is connected to the first power supply terminal of the warm light LW. The second power supply terminal of the warm light LW is connected to the power supply terminal of the warm light drive circuit.
[0085] It should be noted that the preset parameters for lighting can include not only sequential lighting speed and lighting duration, but also the color temperature and power adjustment of the lighting components. This allows the stairwell light to flexibly adjust its lighting effect according to user needs or environmental conditions. In this embodiment, when the first wireless communication and control circuit sends a first PWM signal, this signal is transmitted to the controlled terminal of the first switching transistor Q141 through the first resistor R141. If the first PWM signal is high, the first switching transistor Q141 is turned on, allowing current to flow from the power supply terminal of the cold light drive circuit to the cold light lamp LC, thereby illuminating the cold light lamp LC. The duty cycle of the first PWM signal determines the average current through the cold light lamp LC, thus affecting the brightness of the cold light lamp LC. A high duty cycle means brighter light, while a low duty cycle produces dimmer light. Similarly, when the first wireless communication and control circuit sends a second PWM signal, this signal is transmitted to the controlled terminal of the first switching transistor Q141 through the third resistor R143. If the second PWM signal is high, the second switch Q142 is turned on, allowing current to flow from the power supply terminal of the warm light driver circuit to the warm light LW, thus illuminating the warm light LW. The duty cycle of the second PWM signal determines the average current flowing through the warm light LW, thereby affecting the light brightness. Thus, this embodiment can activate either the cool light LC or the warm light LW, or both simultaneously, to achieve cool light, warm light, and natural light effects respectively, thereby adjusting the color temperature. This embodiment can also adjust the power of the cool light LC / warm light LW by changing the duty cycle of the output PWM signal. This enhances the flexibility of the stairwell light's illumination.
[0086] In one feasible implementation, please refer to Figure 6The first wireless communication and control circuit may include capacitors C151-C157, resistor R151, inductors L151-L152, antenna ANT1, switches K151-K152, crystal oscillator Y151, and a first wireless communication and control chip U4. The first wireless communication and control chip U4 may be an AS76R-16A chip. It should be noted that the AS76R-16A chip is a radio frequency chip used for 2.4GHz band communication. It should also be noted that switch K151 is used to trigger power-on / power-off; switch K152 is used to trigger entry into the coding mode, at which time the first wireless communication and control circuit can receive and update the corresponding coding sequence number.
[0087] In one feasible implementation, please refer to Figure 7 The light intensity detection circuit may include capacitor C161, resistor R161, and phototransistor CDS. The current through the phototransistor CDS changes with the light intensity. It should be noted that the light intensity detection circuit can be turned on / off via remote control circuit 02. When the light intensity detection circuit is on, if the detected light intensity is less than a preset intensity, it is considered to be in darkness, and if a person is detected in the surrounding environment, the corresponding lighting component will be turned on. If the detected light intensity is greater than or equal to the preset intensity, it is considered to be in daylight, and the corresponding lighting component will not be turned on. When the light intensity detection circuit is off, the lighting drive circuit is no longer controlled based on the light intensity detection signal.
[0088] In one feasible implementation, please refer to Figure 8 The storage circuit may include resistors R171 and R172, capacitor C171, and storage chip U5. Storage chip U5 is responsible for data storage and retrieval, and can be EEPROM, Flash, or other types of non-volatile memory, used to store information such as preset parameters and encoding serial numbers for the LED.

In this mode, when any lighting control circuit 01 senses a human body, multiple lighting components light up simultaneously. If any lighting control circuit 01 detects human activity again during this period, the timer can be reset and the lighting time extended. If any lighting control circuit 01 does not detect further human activity, multiple lighting components will simultaneously turn off after a second time interval. The user can control multiple lighting control circuits 01 to enter sequential lighting mode via trigger switch K226.
