[0002] As a common lighting device, stair lights are widely used in areas such as stairwells or corridors to provide necessary light protection for people's nighttime activities. Commonly used human body sensing stair light systems usually rely on strong power supply and use a main control circuit board to manage multiple light panels distributed on different floors. Although this type of design meets the basic safety lighting needs to a certain extent, it also has some disadvantages.

[0003] Since each light panel needs to be connected to the main control circuit board through an independent control line, the main control chip is required 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 difficulty of installation, but also affects the overall aesthetics of the staircase lights. Moreover, in order to ensure that users can achieve the effect of orderly lighting when going up and down the stairs, the light panels on each layer must be connected in a specific order. When a light panel on a certain layer is damaged, the function of sequential lighting may not be achieved. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0060] In existing stair lights, since each light board needs to be connected to the main control circuit board through 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 boards increases, the wiring complexity also increases, which not only increases the difficulty of installation, but also affects the overall aesthetics of the stair lights. Moreover, in order to ensure that users can achieve the effect of orderly lighting when going up and down the stairs, the light boards on each layer must be connected in a specific order. When a light board on a certain layer is damaged, the function of sequential lighting may not be achieved.

[0061] The present application provides a staircase light circuit.

[0062] See also Figure 1 In one embodiment of the present application, the staircase lamp includes a plurality of lighting components, and the staircase lamp circuit includes a plurality of lighting control circuits 01, a remote control circuit 02, and a coding circuit 03;

[0063] Multiple light control circuits 01 are connected to multiple lighting components in a one-to-one correspondence; multiple light control circuits 01 are sequentially provided with corresponding coding numbers in an increasing / decreasing order, and preset parameters for lighting; wherein each light control circuit 01 is wirelessly connected to at least one light control circuit 01 whose coding number is directly adjacent to the light control circuit 01;

[0064] The light control circuit 01 is used to detect human body information in the surrounding environment where the light control circuit 01 is located. When it is determined that there is a human body in the surrounding environment, the corresponding lighting component is controlled to light up, and human body sensing information with coded serial number information is sent to the remaining light control circuits 01, so as to realize that multiple lighting components light up in sequence according to preset parameters; wherein the preset parameters include a sequential lighting speed and a lighting delay time; the sequential lighting speed is used to indicate a first time interval from the lighting of the previous lighting component to the lighting of the next lighting component, and the lighting delay time is used to indicate a second time interval from the lighting of the lighting component to the extinguishing of the lighting component;

[0065] The remote control circuit 02 is used to wirelessly connect to the light control circuit 01. When triggered by the user, the remote control circuit 02 sends corresponding adjustment instructions to the light control circuit 01 to adjust the preset parameters of the light.

[0066] The coding circuit 03 is used for wireless connection with the light control circuit 01 . When the coding circuit 03 is triggered by a user, it sends a corresponding coding number to the light control circuit 01 to adjust the coding number of the light control circuit 01 .

[0067] It should be noted that when the number of floors of the staircase is relatively small, all the light control circuits 01 can be directly wirelessly connected to each other. In this fully connected mode, there is no need to rely on other intermediate floors for information forwarding between any two light control circuits 01, making information transmission more direct and efficient. In the scenario with more floors, in order to simplify the network structure and ensure the reliability of communication, each light control circuit 01 is at least wirelessly connected to the light control circuit 01 directly adjacent to its coding sequence number. It should be noted that there may be one or two light control circuits 01 with directly adjacent coding sequences. For example, if a plurality of the light control circuits are sequentially provided with corresponding coding sequences in ascending order, the light control circuit 01 with the largest coding sequence number is at least wirelessly connected to the previous light control circuit 01 directly adjacent to its coding sequence number, the light control circuit 01 with the smallest coding sequence number is at least wirelessly connected to the next light control circuit 01 directly adjacent to its coding sequence number, and the light control circuit 01 with the middle coding sequence number is at least wirelessly connected to the two light control circuits 01 directly adjacent to its coding sequence number. In this way, the previous light control circuit 01 and the next light control circuit 01 can form a direct communication link. If information needs to be transferred from one floor to another, it can be forwarded step by step through the light control circuits 01 on the middle floors to ensure that the information can reach the destination along the path. In this way, this embodiment can ensure effective information exchange between the light control circuits 01.

[0068] It should be noted that the lighting assembly may include an LED lamp, and the lighting control circuit 01 may include a human body sensor for detecting human body 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 information, a lighting drive circuit for driving the LED lamp, and a controller for controlling the operation of the above circuit. In one embodiment, it is assumed that there are ten floors of stairs, staircase lights are set on the ten floors of stairs, and a lighting assembly is installed on each floor, and the lighting assembly is controlled by its own lighting control circuit 01. Then in this embodiment, ten lighting control circuits 01 can be set to be connected to the lighting assemblies of the ten floors in a one-to-one correspondence, and the ten lighting control circuits 01 are set with coded sequences in an increasing / decreasing order, for example, from 1 to 10, corresponding to the lighting assembly 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 circuit 01 is installed. And, the preset parameters for lighting are set in advance before installation, including the sequential lighting speed (first time interval) and the lighting delay time (second time interval).

[0069] When someone starts to go upstairs, the human body sensor of the light control circuit 01 on the bottom floor (assuming the code number 1) detects the presence of a person. The light control circuit 01 immediately lights up the corresponding LED light and sends the human body sensing information with its own code number information to the next light control circuit 01 (code number 2). The second light control circuit 01 (code number 2) that receives the human body sensing information lights up its LED light after a delay according to the preset first time interval, and continues to send information wirelessly to the next light control circuit 01. This process can be repeated in the direction of increasing code numbers until the human body sensing information with the code number information is sent to all remaining light control circuits 01 to light up all LED lights. Among them, all LED lights remain on according to the preset second time interval, giving enough time for people to go up and down the stairs safely. If any light control circuit 01 detects human activity again during this period, the timing can be reset and the lighting time can be extended. If no further human activity is detected, after the second time interval, multiple LED lights gradually go out and return to the initial state to wait for the next trigger. In this way, the present embodiment can realize that ten LED lights are sequentially lit according to the preset sequential lighting speed and lighting delay time. It can be understood that if human activity is detected on the middle floor, the LED lights will be sequentially lit from the middle floor to the upper floor and the lower floor. If human activity is detected on the top floor, the LED lights will be sequentially lit from the top floor to the bottom floor. Among them, the user can adjust the preset parameters through the remote control circuit 02, such as changing the sequential lighting speed or the lighting delay time, to adapt to different needs or preferences. Similarly, if the coding sequence number needs to be adjusted (the lighting control circuit 01 is damaged or replaced), it can be adjusted through the coding circuit 03. In this way, the present embodiment can simplify the wiring, and when a certain lighting control circuit 01 is damaged or replaced, the coding circuit 03 can re-code the remaining lighting control circuits 01 in sequence, so as to realize the sequential lighting function, and solve the problems of complex wiring and easy error of sequential lighting in the existing staircase lights.

[0070] In the present application, each lighting component is equipped with a corresponding light control circuit 01. The light control circuit 01 is assigned a coding number in an increasing or decreasing order, and is provided with preset parameters such as sequential lighting speed and lighting delay time. When there are fewer floors, all light control circuits 01 can be directly wirelessly connected to each other; when there are more floors, each light control circuit 01 is wirelessly connected to at least the light control circuit 01 directly adjacent to its coding number to form a complete communication link. When the light control circuit 01 of any floor detects human activity in the surrounding environment, the light control circuit controls the lighting of the corresponding lighting component and sends the human body sensing information with its own coding number to other associated light control circuits 01. The next light control circuit 01 that receives the human body sensing information lights up its lighting component after a preset first time interval, and continues to transmit information to the next light control circuit 01, and so on, to achieve a sequential lighting effect from bottom to top or from top to bottom. All the lit lighting components will remain lit during the set extended time to ensure that the user has enough light to safely go up and down 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 is exceeded and no new activity is detected, the lighting components will be turned off in sequence and restored to the initial state. Among them, the user can adjust the preset parameters such as the sequential lighting speed and the lighting extension time through the remote control circuit 02 to adapt to different usage requirements. Similarly, the user can also adjust the coding sequence of the lighting control circuit 01 through the coding circuit 03, for example, when a lighting control circuit is damaged or replaced, the coding sequence is re-sequenced. In this way, the present application solves the problems of complex wiring and easy errors in sequential lighting in existing staircase lights.

[0071] In one embodiment of the present application, the light control circuit 01 is further configured to send an adjustment instruction to the remaining light control circuits 01 upon receiving an adjustment instruction, so as to achieve synchronous adjustment of preset parameters of the plurality of light control circuits 01 .

[0072] In this embodiment, each light control circuit 01 will receive and forward the adjustment command, and the entire stair light setting can be updated quickly and consistently. The user does not need to access each light control circuit 01 to set it individually, but only needs to initiate an operation through the remote control circuit 02 to adjust the preset parameters of the light control circuit 01 of the entire stair light. In this way, even in a multi-story building, the user can easily adjust the operation of multiple light control circuits 01, reducing the user's operating burden and improving the ease of use of the stair light.

[0073] See also Figures 2 to 8 In one embodiment of the present application, the lighting control circuit 01 includes:

[0074] A lighting driving circuit, the lighting driving circuit is connected to a corresponding lighting component;

[0075] A storage circuit, used for storing the coding 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 light control circuit 01 is located, and send a corresponding infrared sensing signal;

[0077] The first wireless communication and control circuit is electrically connected to the signal interaction end of the storage circuit, the signal input end of the lighting drive circuit, and the signal output end of the human body sensing circuit respectively; the first wireless communication and control circuit is used to receive the infrared sensing signal, and when it is determined according to the infrared sensing signal that there is a human body in the surrounding environment, the lighting drive circuit is controlled to drive the corresponding lighting component to light up, and based on the infrared sensing signal and the coding sequence number, the human body sensing information with the coding sequence number information is sent to the first wireless communication and control circuit of the remaining lighting control circuit 01, so as to realize that multiple lighting components light up sequentially according to preset parameters.

[0078] The lighting control circuit 01 also includes:

[0079] A light intensity detection circuit, which is connected to the first wireless communication and control circuit, and is used to detect the light intensity information of the surrounding environment where the light control circuit 01 is located, and output a corresponding light intensity detection signal;

[0080] The first wireless communication and control circuit is also used to control the operation of the lighting driving circuit based on the light intensity detection signal.

[0081] In one possible implementation, see Figure 4 The human body sensing circuit may include a capacitor C131, an infrared probe PIR, and an infrared detection chip U3. The infrared probe PIR may be a D220AX sensor, which is responsible for receiving changes in infrared radiation from the human body in the surrounding environment and sending the changes to the infrared detection chip U3 in the form of electrical signals. The infrared detection chip U3 may be an AS159A-8A chip, which may perform amplification, filtering, analog-to-digital conversion, and other processing after receiving the electrical signal from the infrared probe PIR, convert it into an infrared sensing signal, and send it to the first wireless communication and control circuit.

[0082] In one possible implementation, see Figure 5 , the lighting component includes a cold light lamp LC and a warm light lamp LW; the lighting driving circuit includes a cold light lamp driving circuit and a warm light lamp driving circuit; the cold light lamp driving circuit includes a first resistor R141, a second resistor R142 and a first switch tube Q141; the warm light lamp driving circuit includes a third resistor R143, a fourth resistor R144 and a second switch tube Q142;

[0083] One end of the first resistor R141 is connected to the first PWM signal output end 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 end of the first switch tube Q141, the other end of the second resistor R142 and the first end of the first switch tube Q141 are grounded, the second end of the first switch tube Q141 is connected to the first power supply end of the cold light lamp LC, and the second power supply end of the cold light lamp LC is connected to the power supply end of the cold light lamp driving circuit;

[0084] One end of the third resistor R143 is connected to the second PWM signal output end 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 end of the second switch tube Q142, the other end of the fourth resistor R144 and the first end of the second switch tube Q142 are grounded, the second end of the second switch tube Q142 is connected to the first power supply end of the warm light lamp LW, and the second power supply end of the warm light lamp LW is connected to the power supply end of the warm light lamp driving circuit.

[0085] It should be noted that the preset parameters for lighting up can include not only the sequential lighting speed and the extended lighting time, but also the color temperature and power adjustment of the lighting assembly, so that the staircase lamp can flexibly adjust the 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, the signal is transmitted to the controlled end of the first switch tube Q141 through the first resistor R141. If the first PWM signal is at a high level, the first switch tube Q141 is turned on, so that the current can flow from the power supply end of the cold light lamp driving circuit to the cold light lamp LC, thereby lighting the cold light lamp LC. Among them, the duty cycle of the first PWM signal determines the average current passing through the cold light lamp LC, which in turn affects the brightness of the cold light lamp LC. A high duty cycle means brighter light, and a low duty cycle produces darker light. Similarly, when the first wireless communication and control circuit sends a second PWM signal, the signal is transmitted to the controlled end of the first switch tube Q141 through the third resistor R143. If the second PWM signal is at a high level, the second switch tube Q142 is turned on, so that the current can flow from the power supply end of the warm light lamp driving circuit to the warm light lamp LW, thereby lighting the warm light lamp LW. Among them, the duty cycle of the second PWM signal determines the average current passing through the warm light lamp LW, which in turn affects the brightness of the light. In this way, the present embodiment can only turn on the cold light lamp LC or the warm light lamp LW, or turn on the cold light lamp LC and the warm light lamp LW at the same time, to achieve the effects of cold light, warm light and natural light respectively, so as to achieve the purpose of adjusting the color temperature. The present embodiment can also achieve power regulation of the cold light lamp LC / warm light lamp LW by changing the duty cycle of the output PWM signal. In this way, the present embodiment enhances the flexibility of the stair lamp lighting.

[0086] In one possible implementation, see Figure 6, the first wireless communication and control circuit may include capacitors C151~C157, resistor R151, inductor L151~L152, antenna ANT1, switches K151~K152, crystal oscillator Y151 and a first wireless communication and control chip U4. Among them, 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 for communication in the 2.4GHz frequency band. It should be noted that the switch K151 is used to trigger power on / off; the switch K152 is used to trigger entering the code matching mode, at which time the first wireless communication and control circuit can receive and update the corresponding coding serial number.

[0087] In one possible implementation, see Figure 7 The light intensity detection circuit may include a capacitor C161, a resistor R161 and a photosensitive tube CDS. The current passing through the photosensitive tube CDS changes with the change of light intensity. It should be noted that the light intensity detection circuit can be turned on / off by the remote control circuit 02. When the light intensity detection circuit is turned on, if it is detected that the light intensity is less than the preset intensity, it is considered to be in a dark state. When it is determined that there is a human body in the surrounding environment, the corresponding lighting component is controlled to light up. If the light intensity is detected to be greater than or equal to the preset intensity, it is considered to be in a daytime state, and the corresponding lighting component is not controlled to light up. When the light intensity detection circuit is turned off, the lighting drive circuit is no longer controlled based on the light intensity detection signal.

In this way, this embodiment greatly simplifies the wiring work, reduces the installation cost, and improves the flexibility and maintainability of the stair lights, and reduces the possibility of errors when the stair lights are lit in sequence.

It can be understood that the parameters such as color temperature, power, sequential lighting speed, and lighting delay time of the lighting component can be set in multiple gears. Each time the switch is pressed, it enters the next gear until it is pressed again at the highest gear to re-enter the lowest gear for setting. For example, the color temperature may include three levels: white light, natural light, and warm light, which can be adjusted through the switch K221, and the indicator light D241 will indicate a successful adjustment.

[0106] It should be noted that in this embodiment, multiple lighting lamps can also be set to work in full-brightness mode. The user can control multiple lighting control circuits 01 to enter full-brightness mode by triggering switch K225. In this mode, when any lighting control circuit 01 senses a human body, multiple lighting components light up at the same time. If any lighting control circuit 01 detects human activity again during this period, the timing can be reset and the lighting time can be extended. If any lighting control circuit 01 does not detect further human activity, after a second time interval, multiple lighting components are synchronously extinguished. The user can control multiple lighting control circuits 01 to enter sequential lighting mode by triggering switch K226.
