In daily life, in order to avoid manual control of the switches of some lamps by personnel, a voice-operated inductive switch can be arranged on the lamp, and a switch element of the voice-operated inductive switch is connected in series in a loop formed by a light source module and a power supply module. When a sound sensor of the sound control inductive switch detects sound, a switch element in the sound control inductive switch is conducted so that the light source module can emit light; otherwise, the switch element in the voice-operated inductive switch is switched off so that the light source module does not emit light.
However, when the voice-activated inductive switch is used to control the on/off of the lamp, if the ambient noise is relatively high, the lamp is easily affected by the external noise, and the switching frequency of the light source module is relatively high and is mostly meaningless, resulting in a greatly reduced lifetime. Therefore, the reliability of the existing lamp capable of realizing the automatic switching function is low.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It should be apparent that the described embodiments are only one component embodiment of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In daily life, in order to avoid manual control of switches of some lamps by personnel, voice-operated switches can be arranged on the lamps. Taking the voice-operated inductive switch as an example, a switch element of the voice-operated inductive switch is connected in series in a loop formed by the light source module and the power supply module, and when a sound sensor of the voice-operated inductive switch detects sound, the switch element in the voice-operated inductive switch is conducted so that the light source module can emit light; otherwise, the switch element in the voice-operated inductive switch is switched off so that the light source module does not emit light.
Disadvantages of voice activated inductive switches include: 1. the lamp is easy to be affected by external noise, and the switching frequency of the light source module is very high, so that the service life of the lamp is greatly reduced. 2. The sensitivity is difficult to adjust to a proper state, if the sensitivity is too high, light pollution is easily caused, the service life of the light source module is easily reduced, and if the sensitivity is too low, the light source module can be conducted only by triggering with sound with high decibel.
Because the existing automatic lamp switch depends on the voice-operated inductive switch, the reliability of the function of the existing automatic lamp switch is low, and the light source module cannot be accurately and sensitively switched on or switched off.
Therefore, the embodiment of the invention provides a lamp and a lamp control method.
Example 1
An embodiment of the invention provides a lamp, as shown in fig. 1, the lamp 100 may include: the three-dimensional image capturing device comprises a light source module 10, a first power supply module 20, a three-dimensional image capturing sensor 30 and a processor 40. The first power module 20 is connected to the light source module 10 and outputs power to the light source module 10, and the light source module 10 is used for emitting light. The three-dimensional image collecting sensor 30 is disposed in the irradiation space of the lamp 100, and is configured to collect three-dimensional image information of the irradiation space of the lamp 100. The processor 40 is connected to the three-dimensional image capturing sensor 30, and determines a scene of an illuminable area of the lamp according to the three-dimensional image information captured by the three-dimensional image capturing sensor 30 to determine a target illumination mode of the lamp 100. In the embodiment of the present invention, the three-dimensional image information in the illuminable region of the lamp is acquired by the three-dimensional image acquisition sensor 30, and the three-dimensional image information can be accurately and sensitively acquired in complex environments such as noise, so as to accurately and sensitively control the illumination mode of the lamp, thereby reducing the probability that the light source module in the lamp 100 frequently and pointlessly performs on-off operation due to the influence of noise.
In the embodiment of the present invention, the three-dimensional image capturing sensor 30 may be configured as a Time of Flight (ToF) sensor, and may still accurately and sensitively obtain the three-dimensional image information in complex environments such as noise, so as to accurately and sensitively control the on/off of the lamp 100, thereby reducing the probability that the light source module 10 in the lamp 100 frequently and meaninglessly performs on/off operations due to the influence of noise. Moreover, when the difference between the body temperature of the human body and the external environment temperature is not large, the three-dimensional image information can be accurately and sensitively acquired, and the on/off of the lamp 100 is accurately and sensitively controlled. Compared with a voice-operated switch, the on/off of the light source module 10 is realized based on the ToF sensor in the embodiment of the invention, so that the lamp 100 in the embodiment of the invention has higher reliability.
Of course, the three-dimensional image capturing sensor 30 may also be configured as other sensors capable of capturing three-dimensional image information, and will not be described herein.
The working principle of the ToF sensor for acquiring three-dimensional image information is that the sensor emits modulated near-infrared light which is reflected after meeting an object, the distance of a shot scene is converted by the sensor through calculating the time difference or phase difference between light emission and reflection so as to generate depth information, and in addition, the three-dimensional outline of the object can be presented in a topographic map mode that different colors represent different distances by combining with the shooting of a traditional camera. Since it is the prior art to acquire three-dimensional image information based on the ToF sensor and acquire human body information in a space based on the ToF sensor, the detailed description is omitted here.
The processor 40 may be a microcontroller or a microprocessor 40 or a single chip microcomputer. In addition, the light source module 10 may be disposed in the housing of the luminaire 100, and the processor 40 may be disposed in the housing of the luminaire 100 together with the light source module 10, that is, the processor 40 may be disposed adjacent to the light source module 10; of course, as a variant, the processor 40 may also be provided on a server; the method can be specifically set according to actual needs.
In the embodiment of the present invention, after different scenes of the illuminable area of the lamp 100 are determined according to the three-dimensional image information in the illuminable area acquired by the time-of-flight sensor, different lighting modes of the lamp 100 can be determined, so that the lighting modes of the lamp 100 can meet the requirements of different scenes.
In an embodiment of the present invention, the scene of the illuminable area of the luminaire 100 includes, but is not limited to, at least one of the following: the number of people in the illuminable area, the purpose of the illuminable area, the height of the person in the illuminable area, and the distance between the person in the illuminable area and the lamp 100.
The lighting modes of the luminaire 100 described above include, but are not limited to: luminous flux, illuminance at a preset distance, color temperature, brightness, color rendering index, and brightness of the lamp 100.
For example, when the number of people in the illuminable area is 0, the lighting mode corresponding to the luminaire 100 may be to turn off the circuit of the light source module 10 to turn off the light emitting unit.
Uses of the illuminable region include, but are not limited to: office, visitor, wash, cooking, i.e., the installation environment of the light fixture 100 determines the purpose of its illuminable area. The color temperature of the light emitted from the light source module 10 in the luminaire 100 can be different according to the application of the illuminable region, for example, the color temperature of the light emitted from the light source module 10 can be higher when the luminaire is in office or for guests, and the color temperature of the light emitted from the light source module 10 can be lower when the luminaire is used for washing or cooking. In addition, the color rendering index of the emergent light of the light source module 10 in the luminaire 100 may be different according to the usage of the illuminable area, for example, the display index of the emergent light of the light source module 10 in office or guest may be lower, and the color rendering index of the emergent light of the light source module 10 in washing or cooking may be higher.
The height of the human body in the irradiation area can be set to a critical value, if the height is lower than the critical value, it is determined that there is a minor in the irradiation area, otherwise, it is an adult, and in combination with the purpose of the illumination area, such as a guest meeting, the emergent light from the light source module 10 of the lamp 100 can be colorful, that is, the color of the emergent light can be colorful in the illumination mode of the lamp 100, so as to cater to the preference of the minor.
The closer the distance between the lamp 100 and the human body in the irradiation area is, the less brightness of the lamp 100 may be. For example, when it is determined that the distance between the human body in the illuminable area and the lamp 100 is less than 0.5 m, the target lighting mode corresponding to the lamp 100 is that the luminous flux of the lamp 100 is 1000 lumens; alternatively, when it is determined that the distance between the human body in the illuminable area and the lamp 100 is greater than 1 meter, the target lighting mode of the corresponding lamp 100 is that the luminous flux of the lamp 100 is 800 lumens.
In the embodiment of the present invention, the processor 40 may further be connected to the first power module 20, and the first power module 20 outputs the electrical parameter adjustable setting to the light source module 10.
In an embodiment of the present invention, the electrical parameter may include a voltage, a current, or a power output to the light source module 10 to change the light performance of the light emitted from the light source module 10.
In another embodiment, the light source module 10 may include a first light emitting unit 11 and a second light emitting unit 12, and optical parameters of the first light emitting unit 11 and the second light emitting unit 12 are different, and different optical effects may be obtained by inputting electrical parameters of different proportions to the first light emitting unit 11 and the second light emitting unit 12. At this time, the electrical parameters output from the first power module 20 to the light source module 10 include the ratio of voltage, current or power output to different light emitting units. For example, there are two light emitting units with different color temperatures in the light source module 10, and the electrical parameters output from the first power module 20 to the light source module 10 include power (or voltage, current) output to the first light emitting unit 11 and power (or voltage, current) output to the second light emitting unit 12. When the optical parameters of the first and second light emitting units 11 and 12 are different, the optical parameters of the light source module 10 may be changed by changing the conductive parameters input to both.
Optical parameters include, but are not limited to, color temperature, color rendering index, and color, among others.
For example, three primary color light emitting units of red, green and blue may be disposed in the light source module 10, so that adjusting the power ratio output to the light emitting units of different colors may change the color of the emergent light of the light source module 10. For another example, light sources with different color temperatures or color rendering indexes may be disposed in the light source module 10, so that the color temperature or color rendering index of the emitted light of the light source module 10 can be changed by adjusting the power ratio output to the light emitting units with different color temperatures or color rendering indexes.
Of course, when there is only one light emitting unit in the light source module 10, the optical parameters of the light emitted from the light source module 10 may be changed by supplying different electrical parameters to the light emitting unit.
In the embodiment of the present invention, the lamp 100 may further include a switch element 50, the processor 40 is connected to the switch element, and the switch element 50 is connected in series to a loop where the light source module 10 and the first power module 20 are located, so that after the lamp 100 determines the lighting mode thereof, on/off of the switch element 50 may be controlled according to needs, thereby controlling on/off of the light source module 10, and implementing lighting or extinguishing of a light emitting unit on the light source module 10.
The processor 40 is connected to the three-dimensional image capturing sensor 30 and the switching element 50, and the switching element 50 is connected in series to the light source module 10 and the power supply module.
In one embodiment, the light source module 10 may further include a control chip, and the processor 40 is connected to the control chip and determines a control signal output to the control chip according to the three-dimensional image information collected by the ToF sensor. The control chip performs dimming control on the light emitting unit of the light source module 10 according to a control signal, where the control signal may be a pulse width modulation signal, so as to make the light emitting unit of the light source module 10 become bright or dark, or control the light emitting unit to flash.
The lamp 100 may further include a second power module, where the second power module is connected to the processor 40 and provides power for the processor 40.
Example 2
The embodiment of the present invention provides a method for controlling a lamp 100, where the lamp 100 may be the lamp 100 of embodiment 1, or may be another lamp 100.
In one embodiment, as shown in fig. 2, the luminaire 100 control method includes:
s204: and acquiring three-dimensional image information acquired by the three-dimensional image acquisition sensor 30 in the irradiation area of the lamp 100.
S206: according to the three-dimensional image information, a scene of an illuminable area of the luminaire 100 is determined.
S208: and determining a target lighting mode of the lamp 100 according to the scene of the illumination area based on the preset corresponding relationship between the scene and the lighting mode.
In the control method of the lamp 100 in the embodiment of the present invention, the three-dimensional image capturing sensor 30 is disposed in the illuminable region of the lamp 100, and after the three-dimensional image capturing sensor 30 obtains the three-dimensional image information of the illuminable region, the scene of the illuminable region of the lamp 100 is determined, and the target illumination mode of the lamp 100 on the illuminable region is determined based on the preset correspondence between the production and the illumination mode. Since the three-dimensional image acquisition sensor 30 is a flight sensor, the three-dimensional image information can be accurately and sensitively acquired in complex environments such as noise, and the on/off of the lamp 100 can be accurately and sensitively controlled, so that the control of the lamp 100 in the control method of the lamp 100 according to the embodiment of the present invention is more reliable.
Wherein, in step S204, the three-dimensional image acquisition sensor 30 may be configured as a time-of-flight sensor; of course, other sensors capable of acquiring three-dimensional image information may be used, and are not described herein again.
The illuminable area of the lamp 100 is the maximum area that the lamp 100 can illuminate, and usually the maximum illumination area of the lamp 100 is fixed after the installation.
The scene of the illuminable area of the luminaire 100 includes, but is not limited to, at least one of the following: the number of people in the illuminable area, the purpose of the illuminable area, the height of the person in the illuminable area, and the distance between the person in the illuminable area and the lamp 100.
The lighting modes of the luminaire 100 described above include, but are not limited to: luminous flux, illuminance at a preset distance, color temperature, brightness, color rendering index, and brightness of the lamp 100.
Therefore, after different scenes of the illuminable area of the lamp 100 are determined according to the three-dimensional image information in the illuminable area acquired by the flight time sensor, different lighting modes of the lamp 100 can be determined, and therefore the lighting modes of the lamp 100 can meet the requirements of different scenes.
For example, when the number of people in the illuminable area is 0, the lighting mode corresponding to the luminaire 100 may be to turn off the circuit of the light source module 10 to turn off the light emitting unit.
Uses of the illuminable region include, but are not limited to: office, visitor, wash, cooking, i.e., the installation environment of the light fixture 100 determines the purpose of its illuminable area. The color temperature of the light emitted from the light source module 10 in the luminaire 100 can be different according to the application of the illuminable region, for example, the color temperature of the light emitted from the light source module 10 can be higher when the luminaire is in office or for guests, and the color temperature of the light emitted from the light source module 10 can be lower when the luminaire is used for washing or cooking. In addition, the color rendering index of the emergent light of the light source module 10 in the luminaire 100 may be different according to the usage of the illuminable area, for example, the display index of the emergent light of the light source module 10 in office or guest may be lower, and the color rendering index of the emergent light of the light source module 10 in washing or cooking may be higher.
The height of the human body in the irradiation area can be set to a critical value, if the height is lower than the critical value, it is determined that there is a minor in the irradiation area, otherwise, it is an adult, and in combination with the purpose of the illumination area, such as a guest meeting, the emergent light from the light source module 10 of the lamp 100 can be colorful, that is, the color of the emergent light can be colorful in the illumination mode of the lamp 100, so as to cater to the preference of the minor.
The closer the distance between the lamp 100 and the human body in the irradiation area is, the less brightness of the lamp 100 may be. For example, when it is determined that the distance between the human body in the illuminable area and the lamp 100 is less than 0.5 m, the target lighting mode corresponding to the lamp 100 is that the luminous flux of the lamp 100 is 1000 lumens; alternatively, when it is determined that the distance between the human body in the illuminable area and the lamp 100 is greater than 1 meter, the target lighting mode of the corresponding lamp 100 is that the luminous flux of the lamp 100 is 800 lumens.
In this embodiment of the present invention, after S208, the method may further include: according to the target lighting pattern of the luminaire 100, at least one of the following is controlled: the on/off of the switch element 50, the electrical parameter output by the first power module 20 to the light source module 10, or the control signal output to the control chip.
For example, after determining the target illumination mode of the luminaire 100, the on/off of the switching element 50 may be controlled to operate the luminaire 100 in the target illumination mode, and of course, the target illumination mode at this time may be that the light source module 10 is turned on, or that the light source module 10 is turned off.
For example, after determining the target lighting mode of the luminaire 100, the electrical parameters output to the light source module 10 by the first power supply module 20 are controlled, which may include voltage, current or power output to the light source module 10. In addition, the electrical parameters output from the first power module 20 to the light source module 10 may further include voltage, current or power output to different light emitting units.
For example, after determining the target lighting mode of the luminaire 100, the control signal output to the control chip is controlled to enable the light emitting unit on the light source module 10 to perform dimming control on the light emitting unit of the light source module 10 according to the control signal, where the control signal may be a pulse width modulation signal to enable the light emitting unit of the light source module 10 to be bright or dark, or to control the light emitting unit to flash.
Before S204, the method may further include: and constructing the corresponding relation between the scene and the lighting mode. The corresponding relationship may be directly written into the processor 40, or may be a corresponding relationship obtained by the processor 40 through learning training.
In another embodiment, as shown in fig. 3, the luminaire 100 control method includes:
s304: and acquiring three-dimensional image information acquired by the three-dimensional image acquisition sensor 30 in the irradiation area of the lamp 100.
S306: according to the three-dimensional image information, the total number of people in the irradiation area of the lamp 100 is determined.
S308: and determining the target luminous flux of the lamp 100 according to the total number of people in the irradiation area of the lamp 100 based on the corresponding relation between the preset total number of people and the luminous flux.
In the control method of the lamp 100 in the embodiment of the present invention, the three-dimensional image collecting sensor 30 is disposed in the illuminable region of the lamp 100, and after the three-dimensional image information of the illuminable region is collected by the three-dimensional image collecting sensor 30, the total number of people in the illuminable region of the lamp 100 is determined, and the target luminous flux of the lamp 100 is determined according to the total number of people. Wherein, in the corresponding relation between the preset total number of people and the luminous flux, the total number of people can be in positive correlation with the luminous flux. Of course, when the total number of persons is not zero, the total number of persons and the luminous flux may be in a negative correlation. Thus, the luminaire 100 can automatically determine the luminous flux output by the luminaire 100 according to the total number of people in the illuminated area.
The three-dimensional image capturing sensor 30 may be a time-of-flight sensor.
The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art.
