Description

Technical Field

[0001] The present invention relates to the technical field of indoor lighting equipment, and in particular to an intelligent lighting lamp. Background Art

[0002] In indoor lighting systems, traditional lighting switches are manually operated. However, when lighting is turned on in rooms open to the public, users may not know the location of the switch upon entering the room, causing inconvenience to users. If the lights are always on, energy is wasted. Therefore, methods for controlling lighting switches using voice-activated switches and infrared sensors have been proposed. However, voice-activated lighting control is only suitable for short-term lighting applications. When continuous lighting is required, continuous sound generation is required to keep the lights on, which is extremely inconvenient.

[0003] When infrared sensors are used to detect people and control the on / off of lights, when a person passes by the door, the infrared sensor will react and the lights in the room will be turned on. In fact, no one has entered the room. Therefore, starting the indoor lights not only wastes electricity, but also shortens the life of the lights. Therefore, it is urgent to propose an intelligent lighting that can control the on and off of the lights according to the status of the people. Summary of the Invention

[0004] In order to solve the problems in the prior art of inconvenient control of traditional manual lighting switches, the inappropriateness of lighting controlled by voice-activated switches for continuous lighting, and the erroneous switch signals easily generated by lighting controlled by infrared sensors, the present invention proposes an intelligent lighting lamp.

[0005] An intelligent lighting lamp comprises a lamp housing, a lampshade arranged below the lamp housing, and a lamp tube clamped below the lampshade, and further comprises:

[0006] The relay is installed in the lamp housing and connected to the lamp tube through a circuit to control the on / off state of the lamp tube;

[0007] The light sensor is fixedly installed under the lampshade and is used to detect the indoor light intensity;

[0008] The detection component includes a motion module that can move outside the lampshade, and a first infrared sensor module and an ultrasonic ranging sensor module with adjustable posture arranged on the motion module, for detecting moving people at the door;

[0009] The second infrared sensor module is fixedly installed at one end of the lamp housing above the lampshade and is used to detect people in the room;

[0010] The processor MCU is set in the lamp housing and is connected to the relay, light sensor, detection component and second infrared sensor module through lines. It is used to collect and process signals from the light sensor, detection component and second infrared sensor, and send control instructions for the lamp switch to the relay to control the lamp status.

[0011] Furthermore, a starter and an electronic ballast are provided at the end of the lamp tube, and the starter and the electronic ballast are connected to a relay.

[0012] Furthermore, a guide rail is provided on the outside of the lampshade, the motion module includes a pulley fitted with the guide rail and a bottom plate provided above the pulley, and the first infrared sensor module and the ultrasonic ranging sensor module are mounted on the bottom plate.

[0013] Furthermore, the first infrared sensing module includes a bracket, a first infrared sensor and an MPU6050 module arranged on the bracket, and the MPU6050 module is fixed to the first infrared sensor.

[0014] Furthermore, the bracket includes an upper section and a lower section and a rotating disk arranged below the lower section, and the upper section and the lower section are hingedly connected by a hinge structure.

[0015] Furthermore, the ultrasonic ranging sensor module includes two servos connected in series at 90 degrees and an ultrasonic ranging sensor and an MPU6050 module arranged at the movable end of the servos, and the ultrasonic ranging sensor and the MPU6050 module are fixed.

[0016] Furthermore, the first infrared sensor module and the second infrared sensor module are both pyroelectric sensor modules.

[0017] Furthermore, the processor MCU sets a light intensity signal threshold inside. When the detection component detects that someone enters the door and the output signal of the light sensor is lower than the threshold, the light tube is turned on through the relay, otherwise the light tube remains off.

[0018] Furthermore, when the second infrared sensor module detects that a person has left the room, the processor MCU turns off the light tube via a relay.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention forms an intelligent lighting lamp that can control the lighting of the lamp according to the status of the personnel through the arrangement of a lamp housing, a lampshade, a lamp tube, a relay light sensor, a detection component, a second infrared sensor module and a processor MCU. The light sensor is used to detect the indoor light intensity to ensure that the lighting lamp is turned off in time when the indoor light intensity is sufficient. The detection component is used to detect moving personnel at the door to ensure the accuracy of the lighting lamp switch information. The second infrared sensor module is used to detect indoor personnel to ensure continuous lighting in the room. When there is no personnel in the room, the lighting lamp is controlled to be turned off in time, further enhancing the intelligence and energy saving of the lighting lamp.

DETAILED DESCRIPTION

[0028] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments:

[0029] As shown in Figures 1 to 6, an intelligent lighting lamp includes a lamp housing 1, a lampshade 2 disposed below the lamp housing 1, and a lamp tube 3 clamped below the lampshade 2, and further includes:

[0030] The relay 4 is provided in the lamp housing 1 and is connected to the lamp tube 3 via a circuit, and is used to control the on / off state of the lamp tube 3;

[0031] The light sensor 5 is fixedly arranged under the lampshade 2 and is used to detect the indoor light intensity;

[0032] The detection component includes a motion module that can move outside the lampshade and a first infrared sensor module 6 and an ultrasonic ranging sensor module 7 with adjustable posture arranged on the motion module, which are used to detect moving people at the door;

[0033] The second infrared sensor module 8 is fixedly arranged at one end of the lamp housing 1 above the lampshade 2 and is used for detecting people in the room;

[0034] The processor MCU9 is arranged in the lamp housing 1 and is connected to the relay 4, the light sensor 5, the detection component and the second infrared sensor module 8 through lines. It is used to collect and process the signals of the light sensor 5, the detection component and the second infrared sensor 8 and to send control instructions for the switch of the lamp tube 3 to the relay 4 to control the state of the lamp tube 3.

[0035] It can be understood that the light sensor 5 is used to detect the light intensity in the room, and the digital output value is 0-65535 Lx. According to the personnel information detected by the first infrared sensor module 6 and the second infrared sensor module 8, when a person enters the room through the door, if the output of the light sensor 5 is higher than 300 Lx, the lights can be turned off, and when it is lower than 300 Lx, the lights are turned on.

[0036] As an implementation method, a starter and an electronic ballast are provided at the end of the lamp tube 3 , and the starter and the electronic ballast are connected to the relay 4 .

[0037] It is understandable that when the starter is disconnected, the electronic ballast generates instantaneous high voltage to make the light emitting device in the lamp tube 3 start to emit light, and then limits the current to control the light emitting device to operate within the rated current range.

[0038] As an implementable embodiment, a guide rail 10 is provided on the outside of the lampshade 2, the motion module includes a pulley 11 that fits with the guide rail 10 and a base plate 12 arranged above the pulley 11, and the first infrared sensor module 6 and the ultrasonic ranging sensor module 7 are installed on the base plate 12.

[0039] As an implementation method, the first infrared sensing module 6 includes a bracket 601 , a first infrared sensor 602 disposed on the bracket 601 , and an MPU 6050 module 13 , wherein the MPU 6050 module 13 is fixed to the first infrared sensor 602 .

[0040] Specifically, the bracket 601 includes an upper section 6011 and a lower section 6012 , and a rotating disk 6013 disposed below the lower section 6012 . The upper section 6011 and the lower section 6012 are hingedly connected via a hinge structure 6014 .

[0041] As an implementation method, the ultrasonic ranging sensor module 7 includes two servos 701 connected in series at 90 degrees and an ultrasonic ranging sensor 702 and an MPU6050 module 13 arranged at the movable end of the servos 701. The ultrasonic ranging sensor 702 and the MPU6050 module 13 are fixed.

[0042] It can be understood that, through the connection between the pulley 11 and the guide rail 10 below the motion module, the connection between the first infrared sensor 602 and the MPU6050 module 13 and the bracket 601, and the connection between the ultrasonic ranging sensor 702 and the MPU6050 module 13 and the servo 701, when the detection assembly is installed, the position of the detection assembly on the guide rail 10 can be adjusted, and the first infrared sensor 602 and the MPU6050 module 13 can be adjusted in two rotational degrees of freedom by rotating the hinge structure 6014 on the bracket 601 and the rotating disk 6013. At the same time, the ultrasonic ranging sensor 702 and the MPU6050 module 13 can be adjusted in two rotational degrees of freedom by two 90-degree series-connected servos 701.

[0043] After rotating the adjustment bracket 601 until the first infrared sensor 602 is aligned with the door, the angle and other posture data can be returned to the processor MCU9 through the MPU6050 module 13. The processor MCU9 controls the servo 701 to make the ultrasonic ranging sensor 702 have the same posture as the first infrared sensor 602, and performs feedback adjustment through the MPU6050 module 13 on the ultrasonic ranging module to make the posture more precise and accurately point to the door.

[0044] As an implementable embodiment, the first infrared sensor module 6 and the second infrared sensor module 8 are both pyroelectric infrared sensor modules.

[0045] It is understandable that the pyroelectric infrared sensor module performs detection by receiving infrared radiation emitted by the human body, thereby ensuring the accuracy of the detection results without being affected by other objects.

[0046] As an implementable method, the processor MCU9 sets a light intensity signal threshold inside. When the detection component detects that someone enters the door and the output signal of the light sensor 5 is lower than the threshold, the lamp 3 is turned on through the relay 4, otherwise the lamp 3 remains off.

[0047] As an implementable embodiment, when the second infrared sensor module detects that a person has left the room, the processor MCU9 turns off the lamp 3 via the relay 4 .

[0048] It can be understood that when someone passes by the door, the first infrared sensor 602 returns data to the processor MCU9, which detects and determines the distance between the person and the lighting lamp through the ultrasonic ranging sensor 702 and the processing of the processor MCU9, and judges whether the distance is reduced, that is, whether the person enters the room from the door. When it is detected that someone outside enters the room, the processor MCU9 determines whether to turn on the lamp 3 through the relay 4 according to the lighting conditions in the room. When the second infrared sensor module 8 detects that there is no one in the entire room, the processor MCU9 turns off the lamp 3 through the relay 4.

[0049] During specific use, when installing the lighting lamp, the installer first adjusts the position of the base plate 12 on the guide rail and rotates the bracket to align the posture of the first infrared sensor with the door. The MPU6050 module fixed to the first infrared sensor returns the angle and posture data of the first infrared sensor to the processor MCU9. The processor MCU9 controls the servo 701 to make the ultrasonic ranging sensor 702 have the same posture as the first infrared sensor 602 based on the obtained angle and posture of the first infrared sensor 602, thereby reducing the installer's repetitive work and facilitating the installation of the lighting lamp.

[0050] The lighting lamp detects whether there is someone at the door through the first infrared sensor 602. When someone is found, the ultrasonic ranging sensor 702 detects the distance between the person and the lighting lamp, and transmits the distance data to the processor MCU9. The processor MCU9 continuously determines whether the distance between the person and the lighting lamp is decreasing, that is, whether the person has entered the classroom. When the distance between the person and the lighting lamp continues to decrease, that is, the person enters the room from the outside, the light sensor 5 detects whether the light intensity in the room is lower than 300Lx. If the light intensity is lower than 300Lx, the processor MCU9 turns on the lamp 3 through the relay 4. If the light intensity is higher than 300Lx, it proves that the light intensity in the room is sufficient and there is no need to turn on the lighting lamp.

[0051] Then, the light sensor 5 is used to detect the indoor light intensity in real time. When the indoor light intensity becomes low and falls below 300Lx, the processor MCU9 adjusts the brightness of the lamp 3 to keep the indoor light intensity at 300Lx. When the person leaves, the second infrared sensor module 8 detects that there is no one in the room, and the processor MCU turns off the light through the relay to save power.

[0052] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
