[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.
[0045] Please see Figure 1 , Figure 1 A schematic diagram of the structure of a lamp 100 provided in an embodiment of this application.
[0046] It is understood that the lamp 100 is an electronic device used to output light. In the embodiments of this application, the type of lamp 100 is not specifically limited. For example, the lamp 100 can be, but is not limited to, a table lamp, wall lamp, chandelier, etc.
[0047] For example, such as Figure 1 As shown, the lamp 100 can be a table lamp with a lamp holder 10.
[0048] In this embodiment, the luminaire 100 may include a light-emitting device 20 and a light control device 30. The light-emitting device 20 is used to output bright light. The light control device 30 is used to detect the environment in which the luminaire 100 is located and control the operation of the light-emitting device 20 according to the detection results.
[0049] Please refer to the following: Figure 2 It can be understood that the light-emitting device 20 has an illumination area 101, and the light-emitting device 20 may have a light-emitting part 23, with the illumination area 101 located at a position corresponding to the light-emitting part 23. When the light-emitting device 20 is working, light is emitted from this light-emitting part 23, thereby increasing the illuminance of the illumination area 101.
[0050] It is understood that the illumination area 101 of the lamp 100 can be determined according to the preset light emission angle and illumination distance of the lamp 100. In the embodiments of this application, the light emission angle and illumination distance of the lamp 100 are not specifically limited.
[0051] Please refer to the following: Figure 3 The light-emitting device 20 may include a first lamp group 21 and a second lamp group 22. The first lamp group 21 is used to output light of a first color, and the second lamp group 22 is used to output light of a second color.
[0052] It's understandable that the primary color and the secondary color can be different colors. The primary color can be a warm color, such as red or orange. The secondary color can be a cool color, such as white or blue.
[0053] It is understandable that the first lamp group 21 and the second lamp group 22 can output different warm and cool light colors respectively. By adjusting the illuminance of the first lamp group 21 and the second lamp group 22, the illuminance of the first lamp group 21 and the illuminance of the second lamp group 22 can be adjusted to achieve different ratios, thereby changing the color and color temperature of the light output by the lamp 100.
[0054] In the embodiments of this application, the types of the first lamp group 21 and the second lamp group 22 are not specifically limited. For example, both the first lamp group 21 and the second lamp group 22 can be integrated lamp groups composed of multiple lamp beads.
[0055] In the embodiments of this application, the type of lamp bead is not specifically limited. For example, the lamp bead can be, but is not limited to, a light-emitting diode (LED), an organic light-emitting diode (OLED), etc.
[0056] In the embodiments of this application, the number of first lamp groups 21 can be one or more, and the number of second lamp groups 22 can be one or more.
[0057] In some scenarios, multiple first light groups 21 and multiple second light groups 22 can be distributed on different sides of the light-emitting device 20. For example, multiple first light groups 21 are located on the first side, and multiple second light groups 22 are located on the second side. In other scenarios, multiple first light groups 21 and multiple second light groups 22 are alternately distributed within the light-emitting device 20. For example, multiple first light groups 21 are spaced apart, multiple second light groups 22 are spaced apart, and adjacent first light groups 21 have second light groups 22 between them, and adjacent second light groups 22 have first light groups 21 between them.
[0058] Please refer to the following in this embodiment: Figure 2 and Figure 3The lighting control device 30 may include a processor 31 and a first detection component 32. The processor 31 is connected to the first lamp group 21 and the second lamp group 22. The first detection component 32 may include a first detection element 321 and a first focusing element 322. The first detection element 321 is connected to the processor 31. The first detection element 321 can detect the illuminance within its detection area. The detection area of the first detection element 321 is the area corresponding to a preset detection angle and detection distance in the direction in which the detection end of the first detection element 321 faces. The first focusing element 322 is integrated and installed on the detection end of the first detection element 321 and is used to configure the detection area of the first detection element 321 in the first region 102. The first region 102 is a sub-region in the illumination region 101.
[0059] In the embodiments of this application, the type of the first detection element 321 is not specifically limited. For example, the first detection element 321 may be, but is not limited to, a reflective lightmeter (RL). It is understood that the first detection element 321 is used to detect the illuminance of light reflected by objects in the first region 102.
[0060] In the embodiments of this application, the type of the first focusing element 322 is not specifically limited. For example, the first focusing element 322 may be a telephoto lens.
[0061] It is understandable that the fixed-focus function of the telephoto lens can limit the detection area of the first detection element 321 to the detection angle and detection distance corresponding to the parameters of the telephoto lens, and reduce the interference of light outside the detection angle and detection distance corresponding to the parameters of the telephoto lens on the detection results of the first detection element 321. For example, when the installation position of the first detection element 321 is close to the light emitting device 20, using the telephoto lens as the first focusing element 322, and ensuring that the detection area corresponding to the working parameters of the telephoto lens is not aligned with the light output from the light emitting device 20, can reduce the influence of the light output from the light emitting device 20 on the detection results of the first detection element 321.
[0062] It is understood that the first detection element 321 is used to detect the illuminance of the light reflected from the first region 102, and outputs illuminance detection information to the processor 31 based on the detection result. The processor 31 is used to determine whether to adjust the emitted illuminance of the light-emitting device 20 based on the illuminance detection information after receiving it, and to adjust the emitted illuminance when it is determined that the emitted illuminance of the light-emitting device 20 needs to be adjusted.
[0063] In the embodiments of this application, the location of the first region 102 is not specifically limited. For example, the first region 102 may be the location where a user places paper materials such as books or notebooks in the irradiation area 101 while working or studying. Exemplarily, the detection angle of the first detection element 321 is configured to be 25° to 30° by the first focusing element 322, and as... Figure 2 As shown, the first region 102 can be an area with a diameter of 50 cm to 70 cm within a circular area centered on the light illumination center of the light emitting device 20, located on the first side of the illumination area 101 and corresponding to the detection angle of the first detection element 321. The first side can be as follows: Figure 2 The side corresponding to the X direction shown.
[0064] It is understood that after receiving illuminance detection information, the processor 31 can determine the illuminance parameter based on the illuminance detection information and determine whether the illuminance parameter exceeds a preset illuminance range. When it is determined that the illuminance parameter is within the illuminance range, the processor 31 may not limit the illuminance of the light-emitting device 20. When it is determined that the illuminance parameter exceeds the illuminance range, the processor 31 can adjust the illuminance of the light-emitting device 20 according to the difference between the illuminance parameter and the upper or lower limit of the illuminance range.
[0065] The processor 31 can determine whether the illuminance parameter is within the illuminance range by comparing its value with the upper and lower limits of the illuminance range. If the illuminance parameter is less than the lower limit of the illuminance range or greater than the upper limit of the illuminance range, the illuminance parameter is outside the illuminance range.
[0066] After determining that the illuminance parameter exceeds the illuminance range, processor 31 calculates the illuminance difference between the illuminance parameter and the illuminance reference value within the illuminance range. In response to the illuminance parameter being less than the lower limit of the illuminance range, processor 31 increases the illuminance of the light-emitting device 20 by increasing the illuminance difference; or in response to the illuminance parameter being greater than the upper limit of the illuminance range, processor 31 decreases the illuminance of the light-emitting device 20 by decreasing the illuminance difference. After adjusting the illuminance of the light-emitting device 20, the illuminance parameter detected by the first detection element 321 is within the illuminance range.
[0067] In the embodiments of this application, no specific limitation is made on the value of the illuminance reference value. For example, the illuminance reference value can be the median value within the illuminance range.
[0068] In the embodiments of this application, the numerical range of the illuminance interval is not specifically limited. For example, the illuminance interval can be [400, 500), and the unit of the value is lux. Thus, the illuminance reference value can be 450 lux.
[0069] It is understandable that the illuminance range can be set according to the influence of light color temperature on human eye comfort. When the illuminance parameter is within the illuminance range, the illuminance of the light reflected by the first region 102 is within the illuminance range where the probability of discomfort after human eye exposure is low.
[0070] In the embodiments of this application, the method by which the processor 31 adjusts the illuminance of the light-emitting device 20 is not specifically limited. For example, the processor 31 can adjust the duty cycle of the pulse signals output to the first lamp group 21 and the second lamp group 22 through pulse width modulation (PWM) to adjust the illuminance of the first lamp group 21 and the second lamp group 22, thereby adjusting the illuminance of the light-emitting device 20. The method by which the processor 31 adjusts the brightness of the first lamp group 21 and the second lamp group 22 through PWM can refer to common technical means in related fields, and is not limited here.
[0071] Please also refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the lighting control device 30 may further include a second detection component 33. The second detection component 33 may include a second detection element 331 and a second focusing element 332. The second detection element 331 is connected to the processor 31. The second detection element 331 can detect the color of light within its detection area. The detection area of the second detection element 331 is the area corresponding to a preset detection angle and detection distance in the direction in which the detection end of the second detection element 331 faces. The second focusing element 332 is integrated and installed on the detection end of the second detection element 331, and is used to configure the detection area of the second detection element 331 in the second region 103. The second region 103 is a sub-region in the illumination region 101, and the first region 102 and the second region 103 do not overlap.
[0072] In the embodiments of this application, the type of the second detection element 331 is not specifically limited. For example, the second detection element 331 may be, but is not limited to, a reflective colorimeter (RC). It can be understood that the second detection element 331 is used to detect the color of light reflected or transmitted by an object in the second region 103.
[0073] In the embodiments of this application, the type of the second focusing element 332 is not specifically limited. For example, the second focusing element 332 can be a telephoto lens. The function and beneficial effects of the second focusing element 332 using a telephoto lens are the same as or similar to the function and beneficial effects of the first focusing element 322 using a telephoto lens, and will not be described again here.
[0074] It is understood that the second detection element 331 is used to detect the color of the light reflected or projected by the second region 103, and outputs color detection information to the processor 31 based on the detection result. After receiving the color detection information, the processor 31 is used to determine whether to adjust the emitted color of the light-emitting device 20 based on the color detection information, and to adjust the emitted color when it is determined that the emitted color of the light-emitting device 20 needs to be adjusted.
[0075] In the embodiments of this application, the location of the second region 103 is not specifically limited. For example, the second region 103 may be the location where an electronic device with a display screen, such as a laptop or tablet, is placed in the illumination region 101 when the user is working or studying. Exemplarily, the detection angle of the second detection element 331 is configured by the second focusing element 332 to be 15° to 20°, and as... Figure 2 As shown, the second region 103 can be a circular region with a diameter of 10 centimeters, centered on the light-emitting device 20's illumination center.
[0076] It is understood that after receiving color detection information, the processor 31 can determine the color parameters based on the color detection information and determine whether the color parameters exceed a preset color range. When it is determined that the color parameters are within the color range, the processor 31 may not limit the color of the light-emitting device 20. When it is determined that the color parameters exceed the color range, the processor 31 can adjust the color of the light-emitting device 20 according to the difference between the color parameters and the upper or lower limit of the color range.
[0077] The processor 31 can determine whether the color parameter is within the color range by comparing its value with the upper and lower limits of the color range. If the color parameter is less than the lower limit of the color range or greater than the upper limit, the color parameter is outside the color range.
[0078] After determining that the color parameter exceeds the color range, processor 31 calculates the color difference between the color parameter and the color reference value within the color range. In response to the color parameter being less than the lower limit of the color range, processor 31 increases the color difference of the light-emitting device 20; or in response to the color parameter being greater than the upper limit of the color range, processor 31 decreases the color difference of the light-emitting device 20. After adjusting the color of the light-emitting device 20, the color parameter detected by the second detector 331 is within the color range.
[0079] In the embodiments of this application, the numerical range of the color interval is not specifically limited. For example, the color temperature can be used to indicate the color of the light in the second region 103. The color interval can be set according to the influence of the light color temperature on human eye comfort. Specifically, the color interval can be [4000, 5000), and the unit of the value is Kelvin (k). Thus, the color reference value can be 4500k.
[0080] It is understood that the first lamp group 21 and the second lamp group 22 are used to output warm-colored light and cool-colored light respectively. After determining that the color parameters exceed the color range, the processor 31 can determine that the color temperature of the light in the second region 103 is within the range that may cause discomfort to the human eye after light exposure. The processor 31 can adjust the color temperature of the light output by the light-emitting device 20 by adjusting the ratio of the illuminance of the light output by the first lamp group 21 and the second lamp group 22, so that the color temperature of the light in the second region 103 is adjusted to a range that does not cause discomfort or has a low probability of causing discomfort to the human eye after light exposure, such as a range greater than or equal to 4000k and less than 5000k.
[0081] In this embodiment, the lighting control device 30 may further include a third detection element 34. The third detection element 34 is connected to the processor 31. The third detection element 34 is used to detect personnel within the illumination area 101 of the light and output personnel detection information to the processor 31. After receiving the personnel detection information, the processor 31 can determine whether personnel are present in the illumination area 101. When it is determined that personnel are present in the illumination area 101, the processor 31 can control the light-emitting device 20 to emit light. When it is determined that there are no personnel in the illumination area 101, the processor 31 can control the light-emitting device 20 to stop emitting light.
[0082] It is understandable that after the lamp 100 is powered on, the third detection element 34 can detect whether a person is present in the illumination area 101. The processor 31 can control the light-emitting device 20 to stop emitting light after determining that a person has left the illumination area 101, thereby reducing the power consumption of the light-emitting device 20. The processor 31 can also control the light-emitting device 20 to emit light after determining that a person has entered the illumination area 101, reducing the steps required for personnel to operate the lamp 100 and improving the user experience.
[0083] In the embodiments of this application, the type of the third detection element 34 is not specifically limited. For example, the third detection element 34 may be, but is not limited to, an infrared sensor based on passive infrared (PIR) detection technology.
[0084] In another embodiment, the luminaire 100 may further include a button device 40. The button device 40 is connected to the processor 31. The button device 40 is used to output trigger information to the processor 31 after being operated, so that the processor 31 adjusts the operating state of the luminaire 100. The operating state of the luminaire 100 may include, but is not limited to, a powered-on state, a powered-off state, a manual adjustment of illuminance, color temperature and on / off state, and an automatic adjustment of illuminance, color temperature and on / off state.
[0085] It is understood that the connection can be a wired communication connection implemented through a signal line, or a wireless communication connection implemented through wireless transmission technologies such as wireless networks, Bluetooth, 3G, 4G, and 5G. The embodiments of this application do not limit this.
[0086] In the embodiments of this application, the installation positions of the light-emitting device 20 and the lighting control device 30 are not specifically limited. For example, as Figure 1 As shown, the light-emitting device 20 and the light control device 30 can be integrated on the top of a lamp, and the orientation of the detection end of the first detection element 321, the detection end of the second detection element 331 and the detection end of the third detection element 34 is the same as the orientation of the light-emitting part 23.
[0087] In the lamp 100 provided in the embodiments of this application, when the lamp 100 is powered on and in automatic illuminance, color temperature and on / off state, the third detection element 34 detects whether there are people in the illumination area 101 of the light-emitting device 20. When people are in the illumination area, the processor 31 controls the first lamp group 21 to turn on and the second lamp group 22 to emit light according to the preset illuminance. Then, the first detection element 321 detects the illuminance of the light reflected by the object in the first area 102, and the second detection element 331 detects the color of the light reflected or projected by the object in the second area 103.
[0088] The first detection element 321 outputs illuminance detection information to the processor 31, and the second detection element 331 outputs color detection information to the processor 31. The processor 31 can determine the illuminance parameters and color parameters based on the illuminance detection information and color detection information, respectively. The processor 31 can determine whether the illuminance parameters are within the illuminance range, determine whether the color parameters are within the color range, and determine whether the color and illuminance of the light-emitting device 20 need to be adjusted based on the determination results. The processor 31 can adjust the color of the light emitted by the light-emitting device 20 by adjusting the illuminance ratio of the first lamp group 21 and the second lamp group 22; and the processor 31 can further adjust the illuminance of the light emitted by the light-emitting device 20 by adjusting the illuminance of the first lamp group 21 and the second lamp group 22.
[0089] Clearly, through the detection of the first detection component 32, the second detection component 33, and the third detection component 34, the processor 31 can adjust the operation, illuminance, and color of the lamp 100 according to the environmental conditions. Furthermore, when the environment of the lamp 100 changes, the lamp 100 can automatically adjust its operation, illuminance, and color according to the new environmental conditions. This reduces the need for manual adjustments when using the lamp 100, improving the user experience.
[0090] Please see Figure 4 and Figure 5In some embodiments, the lighting control device 30 may further include a fourth detection element 35 and an alert unit 36. The fourth detection element 35 is connected to the processor 31. The alert unit 36 is connected to the processor 31. The fourth detection element 35 is used to detect the distance between the person and the fourth detection element 35 when the processor 31 determines, based on the person detection information, that a person is present in the illumination area 101, and outputs distance detection information to the processor 31. The processor 31 is used to determine, based on the distance detection information, whether the detection distance between the person and the fourth detection element 35 is greater than a preset distance threshold, and triggers the alert unit 36 to output alert information when it determines that the detection distance is greater than the distance threshold.
[0091] For example, the lamp 100 can be a table lamp. The fourth detection element 35 can be installed on the top of the table lamp, and the direction in which the detection end of the fourth detection element 35 faces is the same as the direction in which the light-emitting part 23 faces. The fourth detection element 35 can detect the sitting posture of the person using the lamp 100 by detecting the distance between the person and the fourth detection element 35. For example, if the processor 31 determines that the detection distance is greater than the distance threshold based on the distance detection information, it can determine that the person may be hunched over or lying on the plane where the lamp 100 is located. At this time, the processor 31 can trigger the reminder unit 36 to output reminder information to remind the person to correct their sitting posture.
[0092] In the embodiments of this application, the type of the reminder unit 36 is not specifically limited. For example, the reminder unit 36 can be a loudspeaker, and when the reminder unit 36 outputs reminder information, the loudspeaker outputs a preset reminder audio.
[0093] Please see Figure 6 , Figure 6 An embodiment of the present application illustrates a lighting control method. The lighting control method is applied in the processor 31 of the lighting fixture 100.
[0094] Lighting control methods may include the following steps:
[0095] Step S61: Determine whether the personnel have appeared based on the personnel detection information.
[0096] It is understandable that, in response to the luminaire 100 being in an automatic adjustment of illuminance, color temperature and on / off state, the processor 31 begins to execute the lighting control method and enters step S61.
[0097] The processor 31 can determine whether a person is present in the covered area based on the personnel detection information output by the third detection element 34. The principle by which the processor 31 determines whether a person is present based on the personnel detection information can be found in [reference needed]. Figures 1 to 3 The details and related descriptions will not be repeated here.
[0098] Step S62: Control the light emitting device 20 to emit light.
[0099] The principle by which the processor 31 controls the light output of the light-emitting device 20 can be found in [reference needed]. Figures 1 to 3 The details and related descriptions will not be repeated here.
[0100] Step S63: Determine whether the color parameters exceed the color range based on the color detection information.
[0101] The principle by which processor 31 determines whether color parameters exceed the color range can be found in [reference needed]. Figures 1 to 3 The details and related descriptions will not be repeated here.
[0102] It is understandable that after step S63 is executed, if it is determined that the color parameter is within the color range, then step S65 is executed; if it is determined that the color parameter is outside the color range, then step S64 is executed.
[0103] Step S64: Adjust the emitted light color of the light-emitting device 20.
[0104] The principle by which the processor 31 adjusts the emitted light color of the light-emitting device 20 can be found in [reference needed]. Figures 1 to 3 The details and related descriptions will not be repeated here.
[0105] It is understandable that after step S64 is completed, step S65 will proceed.
[0106] Step S65: Determine whether the illuminance parameters exceed the illuminance range based on the illuminance detection information.
[0107] The principle by which processor 31 determines whether the illuminance parameter exceeds the illuminance range can be found in [reference needed]. Figures 1 to 3 The details and related descriptions will not be repeated here.
[0108] It is understandable that after step S65 is executed, if it is determined that the illuminance parameter is within the illuminance range, then step S67 is executed; if it is determined that the illuminance parameter exceeds the illuminance range, then step S66 is executed.
[0109] Step S66: Adjust the light output illuminance of the light output device 20.
[0110] The principle by which the processor 31 adjusts the light output illuminance of the light-emitting device 20 can be found in [reference needed]. Figures 1 to 3 The details and related descriptions will not be repeated here.
[0111] It is understandable that after step S66 is executed, step S67 will proceed.
[0112] Step S67: Determine whether the personnel have left based on the personnel detection information.
[0113] The principle by which the processor 31 determines whether a person has left the irradiation area 101 can be found in [reference needed]. Figures 1 to 3 The details and related descriptions will not be repeated here.
[0114] It is understandable that after step S67 is executed, if it is determined that the person has not left the irradiation area 101, the process returns to step S63; if it is determined that the person has not left the irradiation area 101, the process proceeds to step S68.
[0115] Step S68: Control the light-emitting device 20 to shut down.
[0116] It is understood that when a person leaves the irradiation area 101, the processor 31 can turn off the light-emitting device 20 and return to step S61 to continue determining whether the person is present in the irradiation area 101.
[0117] In the embodiments of this application, steps S63 and S64 can be executed before or after steps S65 and S66. When steps S63 and S64 are executed after steps S65 and S66, step S62 is executed and then step S65 is entered; after step S65 is executed, if it is determined that the illuminance parameter is within the illuminance range, step S63 is entered; if it is determined that the illuminance parameter exceeds the illuminance range, step S66 is entered and then step S63 is entered. After step S63 is executed, if it is determined that the color parameter is within the color range, step S67 is entered; if it is determined that the color parameter is within the color range, step S64 is entered, and then step S64 is entered and then step S67 is entered.
[0118] Please refer to the following: Figure 7 In some embodiments, the lighting control method may further include steps S71 and S72. Steps S71 and S72 can be performed as follows: Figure 4 and Figure 5 The processor 31 shown.
[0119] Steps S71 and S72 can be executed between steps S62 and S67. When steps S63 to S66 are running, steps S71 and S72 run synchronously, and the execution of steps S63 to S66 does not interfere with the execution of steps S71 and S72.
[0120] Step S71: Determine whether the distance parameter is greater than the distance threshold based on the distance detection information.
[0121] The processor 31 receives distance detection information and determines the distance parameters and whether the distance parameters are greater than the distance threshold based on the distance detection information. (See also...) Figure 4 , 5 The details and related descriptions will not be repeated here.
[0122] It is understandable that after determining that the distance parameter is greater than the distance threshold, the process proceeds to step S72; after determining that the distance parameter is less than or equal to the distance threshold, the process proceeds to step S67.
[0123] Step S72: Control reminder unit 36 to output reminder information.
[0124] It is understandable that when the processor 31 determines that the distance parameter is greater than the distance threshold, it can trigger the reminder unit 36 to output a reminder message to remind the person to correct their sitting posture.
[0125] It is understandable that after step S72 is completed, step S67 will proceed.
[0126] In other embodiments, steps S71 and S72 can be performed as follows: Figure 6 Between steps S62 and S63 shown, or during the process of running as follows Figure 6 Between steps S64 and S65 shown, or during the process of running as follows Figure 6 Between steps S66 and S67 shown.
