Illumination control device

Abstract

The embodiment of the utility model relates to the technical field of light-emitting equipment, in particular to illumination control equipment. The surface, close to the light source, of the dustproof part is defined as a first surface. The higher the pollution level of the first surface is, the higher the light intensity of the infrared reflection light is, and the larger the corresponding illumination compensation value is. Therefore, the illumination intensity of the infrared reflection light and the illumination compensation value have a mapping relation. The controller can determine the target illumination compensation value through the current light intensity of the infrared reflection light rays obtained by the infrared receiver and the mapping relation, and adjusts the current illumination of the light source based on the current illumination of the light source, the target illumination compensation value and the preset target illumination to obtain the adjusted and increased illumination of the light source. Therefore, the controller can compensate the current illuminance, detected by the light intensity sensor, of the light source through the target illuminance compensation value, so that the difference between the adjusted illuminance of the light source and the preset target illuminance is reduced, and the influence of pollutants on the illuminance control precision of the light source is reduced.

Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of light-emitting devices, and in particular, to an illumination control device. Background Art

[0002] Lamps, such as table lamps and stage lamps, are an indispensable part of our daily life. With the development and progress of science and technology, lamps can be equipped with controllers and light intensity sensors; the controller can detect the current illumination of the lamp through the light intensity sensor, and adjust the illumination of the light source based on the deviation between the current illumination and the preset illumination, so as to adjust the illumination of the light source to the preset illumination, thereby realizing intelligent adjustment of the illumination of the light source.

[0003] At present, the light intensity sensor is usually set on the outer surface of the lamp and encapsulated by a transparent dustproof piece at a certain position of the lamp housing. The light emitted by the light source of the lamp can be received by the light intensity sensor through the dustproof piece to monitor the illumination of the light source. However, when the surface of the dustproof piece is covered with pollutants, the illumination of the light source monitored by the light intensity sensor will be low, reducing the control accuracy of the controller on the illumination of the light source. Utility Model Content

[0004] The embodiment of the present application provides an illumination control device, which can reduce the influence of pollutants on the surface of the dustproof part on the illumination control accuracy of the light source.

[0005] An embodiment of the present application provides an illumination control device, which includes: a light source; a transparent dustproof piece; a light intensity sensor, wherein the light intensity sensor is arranged within the light emitting range of the light source, and the light intensity sensor is used to receive the light from the light source passing through the dustproof piece to detect the illumination of the light source; an infrared transmitter, wherein the infrared transmitter is used to transmit infrared emission light toward the dustproof piece; an infrared receiver, wherein the infrared receiver is used to receive infrared reflected light to detect the light intensity of the infrared reflected light; a controller, wherein the controller is communicatively connected with the light source, the light intensity sensor, the infrared transmitter and the infrared receiver; wherein the infrared reflected light is used to represent the light formed after the infrared emission light is reflected by the dustproof piece, and the dustproof piece is used to encapsulate the light intensity sensor, the infrared transmitter and the infrared receiver.

[0006] In an embodiment of the present application, the surface of the dustproof piece close to the light source is defined as the first surface. Since the first surface is exposed to the external environment, the first surface is prone to accumulate dust and other pollutants in the environment. The light intensity sensor monitors the light intensity of the light source based on the light of the light source penetrating from the first surface of the dustproof piece. When the first surface is contaminated by pollutants, the pollutants will prevent the light of the light source from passing through the dustproof piece, resulting in the current light intensity of the light source monitored by the light intensity sensor being lower than the actual light intensity of the light source. The pollutants will also prevent the infrared emission light from passing through the dustproof piece, resulting in an increase in the light intensity of the infrared reflected light received by the infrared receiver. In addition, the higher the pollution level of the first surface, the higher the light intensity of the infrared reflected light, and the larger the corresponding illumination compensation value. Therefore, there is a mapping relationship between the illumination intensity of the infrared reflected light and the illumination compensation value. The controller can determine the target illumination compensation value based on the current light intensity of the infrared reflected light obtained by the infrared receiver, and the mapping relationship between the light intensity of the infrared emission light and the light intensity compensation value, and adjust the current illumination of the light source based on the current illumination of the light source, the target illumination compensation value and the preset target illumination to obtain the illumination of the light source after the adjustment. Therefore, the controller can compensate the current illumination of the light source detected by the light intensity sensor through the target illumination compensation value, thereby reducing the gap between the illumination of the adjusted light source and the preset target illumination, and reducing the impact of pollutants on the illumination control accuracy of the light source.

Figure 1 and Figure 2 As shown, the illumination control device 100 includes a main body 110 and a light source 120 installed on the main body 110. The light emitting range of the light source 120 is range B. When the light source 120 is in working state, the light source 120 emits light L1 within range B. The light source 120 can be any suitable lamp, for example, an LED lamp, an incandescent lamp or a metal halide lamp.

Figure 1 The illumination control device 100 is taken as a desk lamp as an example for description.

[0026] In some embodiments, the illumination control device 100 further includes a light intensity sensor 130. The light intensity sensor 130 is mounted on the main body 110, and the light intensity sensor 130 is disposed within the range B.

[0027] In some embodiments, in order to prevent pollutants (such as dust, oil, etc.) in the external environment from contaminating the light intensity sensor 130, and to prevent pollution from entering and covering the light intensity sensor 130, thereby affecting the detection accuracy of the light intensity sensor 130, the illumination control device 100 also includes a transparent dustproof member 140, and the dustproof member 140 is used to encapsulate the light intensity sensor 130. The dustproof member 140 is disposed between the light source 120 and the light intensity sensor 130. The light intensity sensor 130 is used to receive the light L2 emitted by the light source 120 that penetrates the dustproof member 140, so as to monitor the light intensity of the light source 120 through the light L2. The material of the dustproof member 140 can be glass, plastic, etc. The distance between the dustproof member 140 and the light intensity sensor 130 is a preset distance, and the preset distance is greater than 0.

[0028] Specifically, in some embodiments, the main body 110 is further provided with a first receiving cavity 150, and the light intensity sensor 130 is received in the first receiving cavity 150. The first receiving cavity 150 is connected to the external environment through an opening 151. The dustproof member 140 can be installed at the opening 151, and the dustproof member 140 is used to cover the opening 151, so as to encapsulate the light intensity sensor 130 in the first receiving cavity 150. In this embodiment, the dustproof member 140 can be a dustproof plate.

[0029] In some embodiments, the main body 110 includes a base 111 and a bracket 112, wherein one end of the bracket 112 is connected to the base 111, and the other end of the bracket 112 is connected to the light source 120.

The infrared emitter 160 is disposed around the light intensity sensor 130. The infrared emitter can be specifically accommodated in the first accommodation cavity 150. The infrared emitter 160 is used to emit infrared emission light 11 toward the dustproof member 140.

[0031] In some embodiments, the illumination control device 100 further includes an infrared receiver 170 installed on the main body 110, and the infrared receiver 170 can be specifically accommodated in the first accommodation cavity 150. In some embodiments of the present application, the infrared receiver 170 and the infrared transmitter 160 can be specifically arranged on both sides of the light intensity sensor 130; the installation position of the infrared receiver 170 and the installation position of the infrared transmitter 160 can be symmetrical with respect to the installation position of the light intensity sensor 130. The infrared receiver 170 is used to receive the infrared reflected light 12, wherein the infrared reflected light 12 is used to represent the reflected light formed after the infrared emission light 11 is reflected by the dustproof member 140.

[0032] Please continue reading Figure 2In some embodiments, the light intensity sensor 130, the infrared transmitter 160 and the infrared receiver 170 are contained in the first containing cavity 150. The dustproof member 140 is used to isolate the first containing cavity 150 from the external environment to prevent dust, oil and other pollutants in the external environment from entering the first containing cavity 150, polluting the light intensity sensor 130, the infrared transmitter 160 and the infrared receiver 170, and affecting the operation of the light intensity sensor 130, the infrared transmitter 160 and the infrared receiver 170; for example, reducing the detection accuracy of the light intensity sensor 130 and the infrared receiver 170.

[0033] Figure 3 A partial structural schematic diagram of an illumination control device 100 provided in some other embodiments of the present application is shown, such as Figure 3 As shown, the dustproof member 140 may also be a dustproof cover, which is mounted on the outer surface of the main body 110, and is used to cover the light intensity sensor 130, the infrared transmitter 160, and the infrared receiver 170 described in 160. Specifically, in some embodiments, the dustproof cover includes a top 1401 and a side wall 1402, and the top 1401 and the side wall 1402 enclose a second receiving cavity 1501, and the light intensity sensor 130, the infrared transmitter 160, and the infrared receiver 170 are received in the second receiving cavity 1501.

The light intensity sensor 130 is used to receive the light L2 of the light source 120 passing through the top 1401.

[0034] For example, Figure 4 The hardware structure diagram of the illumination control device 100 provided in some embodiments of the present application is shown. Figure 4 As shown, the illumination control device 100 includes a controller 180 and a light source 120 , a light intensity sensor 130 , an infrared transmitter 160 , and an infrared receiver 170 that are communicatively connected to the controller 180 .

[0035] In this embodiment, the surface of the dustproof member 140 close to the light source 120 is defined as the first surface. Since the first surface is exposed to the external environment, dust and other pollutants in the environment are easily accumulated on the first surface. The light intensity sensor 130 monitors the light intensity of the light source 120 based on the light of the light source 120 penetrating from the first surface of the dustproof member 140. When the first surface is contaminated by pollutants, the pollutants will prevent the light of the light source 120 from passing through the dustproof member 140, resulting in the light intensity of the light source 120 monitored by the light intensity sensor 130 being lower than the actual light intensity of the light source 120. And under the condition that the illumination of the light source 120 remains unchanged, the higher the degree of contamination of the first surface, the lower the light intensity of the light source 120 detected by the light intensity sensor 130. If the controller 180 uses the light intensity of the light source 120 detected by the light intensity sensor 130 as the actual light intensity of the light source 120 and adjusts the illumination of the light source 120, the illumination of the light source 120 will be higher than the preset target illumination, reducing the control accuracy of the illumination of the light source 120 by the controller 180. Furthermore, the higher the contamination degree of the first surface is, the lower the control accuracy of the illumination of the light source 120 by the controller 180 is.

[0036] Therefore, in order to reduce the influence of the pollutants on the dustproof member 140 on the illumination control accuracy of the light source 120, the illumination control device 100 is further provided with an infrared emitter 160, and the controller 180 can control the infrared emitter 160 to emit infrared emission light toward the dustproof member 140. When the first surface of the dustproof member 140 is contaminated by pollutants, the pollutants on the first surface will prevent the infrared emission light from penetrating the dustproof member 140, resulting in an increase in the light intensity of the infrared reflected light. The higher the pollution level of the first surface, the higher the light intensity of the infrared reflected light, and the larger the corresponding illumination compensation value. Therefore, there is a mapping relationship between the light intensity of the infrared reflected light and the illumination compensation value. The controller 180 can obtain the mapping relationship between the light intensity of the infrared reflected light and the illumination compensation value of the light source 120 in advance, determine the target illumination compensation value based on the current light intensity of the infrared reflected light and the mapping relationship between the light intensity of the infrared reflected light and the illumination compensation value, and adjust the illumination of the light source 120 based on the target illumination compensation value, so as to reduce the influence of the pollutants on the illumination control accuracy of the light source 120 through the target illumination compensation value.

[0037] For example, in some embodiments, in order to make the light emitted by the light source 120 more friendly to the human eye, the preset target illuminance of the light source 120 is 300 Lux; that is, when the pollution level of the dustproof part 140 is 0, the controller 180 needs to control the illuminance of the light source 120 based on the preset target illuminance, so as to narrow the gap between the current light intensity of the light source 120 detected by the light intensity sensor 130 and the preset target illuminance. Specifically, in some embodiments, the light intensity of the ambient light obtained by the controller 180 is 0.8 cd, and the total light intensity of the ambient light and the infrared reflected light is 1.0 cd. Then the light intensity of the infrared reflected light calculated by the controller 180 is equal to 1.0 cd-0.8 cd=0.2 cd. The dustproof parts 140 with levels 0 to 10 are marked as M0, M1, M2, ..., M 10 The dustproof parts 140 are M0, M1, M2, ..., M 10 When the light intensity of the light source 120 detected by the light intensity sensor 130 is I'0=0 cd, I'1=0.5 cd, I'2=0.8 cd, ..., I' 10 =2.2 cd. The controller 180 is based on I'0, I'1, I'2, ..., I' 10 The calculated dustproof parts 140 are M1, M2, ..., M 10 The illumination of the light source 120 detected by the light intensity sensor 130 is E0=300Lux, E1=280Lux, E2=260Lux, ..., E 10 =180Lux. Then the dustproof parts 140 calculated by the controller 180 are M0, M1, M2, ..., M 10 The illumination compensation values ​​are △E0=300Lux-300Lux=0Lux, △E1=300Lux-280Lux=20Lux, △E2=300Lux-260Lux=40Lux, ..., △E 10 =300Lux-180Lux=120Lux. The mapping relationship between the light intensity of the infrared reflected light and the illumination compensation value of the light source 120 established by the controller 180 is specifically shown in Table 1. The controller 180 can store the mapping relationship between the light intensity of the infrared reflected light and the illumination compensation value of the light source 120 in the memory.

[0038] Table 1:

[0039] Pollution degree I △E 1 0.5cd 20Lux 2 0.8cd 40Lux … … … 10 2.2cd 120Lux

[0040] Specifically, in some embodiments, if the light intensity of the infrared emission light obtained by the controller 180 is 0.5 cd, the controller 180 can determine that the illumination compensation value of the light source 120 is 20 Lux based on the light intensity of the infrared emission light being 0.5 cd and Table 2. At this time, the controller 180 can determine that the illumination of the light source 120 detected by the light intensity sensor 130 is 20 Lux lower than the actual illumination of the light source 120. In order to adjust the illumination of the light source 120 to 300 Lux, the controller 180 needs to adjust the illumination of the light source 120 so that the illumination of the light source 120 detected by the light intensity sensor 130 is 280 Lux; if the controller 180 adjusts the illumination of the light source 120 so that the illumination of the light source 120 detected by the light intensity sensor 130 is 300 Lux, the actual illumination of the light source 120 has reached 320 Lux, which exceeds the preset target illumination and is not conducive to the protection of human eyes.

[0041] In an embodiment of the present application, there is a mapping relationship between the light intensity of the infrared emission light and the light intensity compensation value of the light source 120. The higher the pollution level of the first surface of the dustproof member 140, the higher the light intensity of the infrared reflected light, and the greater the corresponding illumination compensation value. The controller 180 can determine the target illumination compensation value based on the current light intensity of the infrared reflected light, and the mapping relationship between the light intensity of the infrared emission light and the light intensity compensation value, and adjust the current illumination of the light source 120 based on the current illumination of the light source 120, the target illumination compensation value and the preset target illumination, to obtain the increased illumination of the light source 120. Therefore, the controller 180 can compensate the current illumination of the light source 120 detected by the light intensity sensor 130 through the target illumination compensation value, thereby reducing the gap between the adjusted illumination of the light source 120 and the preset target illumination, and reducing the influence of pollutants on the illumination control accuracy of the light source 120.
