[0026] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to make the technical scheme of the utility model more clear and specific to those skilled in the art, the implementation methods described below are not limited to this. The utility model is further described in detail below in combination with the embodiments and the accompanying drawings.

The terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; "connected" can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0028] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as "up", "down", "left", "right", "front" and "back" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation, and therefore, cannot be understood as a limitation on the present invention.

[0029] The first aspect of the utility model is as follows Figure 1-Figure 4As shown, a light sensing device is provided, including a filter 3 and a light receiving element 2, the filter 3 including a first light-transmitting portion 31, a second light-transmitting portion 32 and a light-blocking portion 33, the light-blocking portion 33 being arranged between the first light-transmitting portion 31 and the second light-transmitting portion 32, for dividing the light-receiving area into a first channel located on one side of the first light-transmitting portion 31 and a second channel located on one side of the second light-transmitting portion 32; the light receiving element 2 includes a first photosensitive element 21 and a second photosensitive element 22 arranged opposite to each other, the first photosensitive element 21 being located in the first channel for acquiring light data in the first channel, and the second photosensitive element 22 being located in the second channel for acquiring light data in the second channel.

[0030] The light sensing device partitions the light receiving area through the light blocking part 33, and divides the light receiving area into two channels in different directions, which can reduce the influence between different channels and facilitate the two relatively arranged photosensitive elements to obtain light data in different channels, so as to facilitate the subsequent further judgment of the intensity and direction of the light.

[0031] Among them, the filtering part is located on the side of the light receiving element 2 facing the light, the light passes through the first light-transmitting part 31 to enter the first channel where the first photosensitive element 21 is located, and the light passes through the second light-transmitting part 32 to enter the second channel where the second photosensitive element 22 is located. The light-blocking part 33 is located between multiple photosensitive elements to reduce the interference of light from other channels on the photosensitive elements, so that the photosensitive elements can obtain the light data of their own channels independently.

[0032] Among them, the number of photosensitive elements is at least two, and the number of photosensitive elements can be two, three, four or other integers. The multiple photosensitive elements are relatively arranged, the number and positions of the light-transmitting parts correspond to the photosensitive elements, and a light-blocking part 33 is provided between two adjacent photosensitive elements. The light-blocking part 33 enables the multiple photosensitive elements to obtain light data in different areas. According to the arrangement of the multiple areas and the difference in the obtained light data, it is convenient to further judge the intensity and direction of the light.

[0033] In one possible implementation, the first light-transmitting portion 31 and the second light-transmitting portion 32 are made of infrared light-transmitting material for allowing infrared light to pass through; the light-blocking portion 33 is made of infrared light-impermeable material, and the light-blocking portion 33 is located between the first photosensitive element 21 and the second photosensitive element 22, and the first channel and the second channel are separated by the light-blocking portion 33.

[0034] Among them, the photosensitive element is used to sense light, mainly the infrared light part of the solar spectrum, that is, the thermal radiation part, and convert the received light signal into an electrical signal.

[0035] The first photosensitive element 21 is used to obtain the light signal passing through the first light-transmitting portion 31 , and the second photosensitive element 22 is used to obtain the light signal passing through the second light-transmitting portion 32 .

[0036] In one possible implementation, Figure 1 As shown, on a surface parallel to the light receiving element 2 , a portion of the light blocking portion 33 is located within the edge projection area of ​​the light receiving element 2 .

[0037] Among them, a part of the light blocking portion 33 is located inside the light receiving element 2 on the plane where the light receiving element 2 is located, that is, on a plane parallel to the light receiving element 2, a part of the light blocking portion 33 is located in the edge projection area of ​​the first photosensitive element 21, and a part of the light blocking portion 33 is located in the edge projection area of ​​the second photosensitive element 22, and some light blocking portions 33 in the edge projection areas of different photosensitive elements are arranged relatively, that is, the width of the light blocking portion 33 is greater than the distance between the first photosensitive element 21 and the second photosensitive element 22, which can greatly reduce the influence between different channels, further increase the distinguishability of obtaining the direction of illumination, and improve the difference in light signals received by the first photosensitive element 21 and the second photosensitive element 22. According to the radiation intensity between the illumination data and the difference in radiation intensity, the approximate polar angle and the approximate azimuth angle of the illumination can be determined, and then the position of the sun relative to the illumination sensor can be determined, thereby improving the accuracy and sensitivity of the illumination sensing device.

[0038] Among them, Figure 2 As shown, in this embodiment, taking the incident parallel light directly on the light receiving element 2 as an example, the illumination area obtained by the first photosensitive element 21 is substantially the same as the illumination area obtained by the second photosensitive element 22. At this time, the illumination data obtained by the first photosensitive element 21 and the illumination data obtained by the second photosensitive element 22 are slightly different.

[0039] Among them, Figure 3 As shown, in this embodiment, taking parallel light incident from the right side of the light receiving element 2 as an example, the illumination area obtained by the first photosensitive element 21 is much smaller than the illumination area obtained by the second photosensitive element 22. At this time, the illumination data obtained by the first photosensitive element 21 and the illumination data obtained by the second photosensitive element 22 are quite different.

[0040] Among them, Figure 4 As shown, in this embodiment, taking parallel light incident from the left side of the light receiving element 2 as an example, the illumination area obtained by the first photosensitive element 21 is much larger than the illumination area obtained by the second photosensitive element 22. At this time, the illumination data obtained by the first photosensitive element 21 and the illumination data obtained by the second photosensitive element 22 are quite different.

[0041] It can be understood that when the radiation intensity received by the first photosensitive element 21 is greater than the radiation intensity received by the second photosensitive element 22, it can be preliminarily determined that the sun is located in the direction of the first photosensitive element 21; when the radiation intensity received by the first photosensitive element 21 is less than the radiation intensity received by the second photosensitive element 22, it can be preliminarily determined that the sun is located in the direction of the second photosensitive element 22; when the radiation intensity received by the first photosensitive element 21 is approximately equal to the radiation intensity received by the second photosensitive element 22, it can be preliminarily determined that the sun is located directly above the first photosensitive element 21 and the second photosensitive element 22, that is, the azimuth range of the sun can be preliminarily determined.

[0042] The range of the azimuth angle can be further narrowed according to the difference between the radiation intensity received by the first photosensitive element 21 and the radiation intensity received by the second photosensitive element 22. The larger the difference between the two, the closer the sun is to the horizontal direction of the light sensor device; the smaller the difference, the closer the sun is to the normal direction of the light sensor device itself.

[0043] It can be understood that when the radiation intensity received by the first photosensitive element 21 and the radiation intensity received by the second photosensitive element 22 are small, it can be preliminarily determined that the sun is approaching the horizon and / or the sunlight is blocked; when the radiation intensity received by the first photosensitive element 21 and the radiation intensity received by the second photosensitive element 22 are large, it can be preliminarily determined that the sun is approaching directly above the light sensing device and / or the sunlight is not blocked, that is, the polar angle and azimuth angle range of the sun can be preliminarily determined.

[0044] The range of the polar angle and the azimuth angle can be further narrowed according to the radiation intensity received by the first photosensitive element 21 and the radiation intensity received by the second photosensitive element 22. The smaller the values ​​of the two are, the closer the sun is to the horizontal direction of the light sensor device; the larger the difference is, the closer the sun is to the normal direction of the light sensor device itself.

[0045] It is understandable that the light sensor mainly senses the infrared part of the solar spectrum and is generally installed in front of the center console of the car near the windshield. When sunlight passes through the front windshield of the car and irradiates the photosensitive element under the filter 3, the light blocking part 33 cooperates with the filter 3 to change the shielding of sunlight, causing the output signal of the left and right channel photosensitive elements to change. Finally, the position of the sunlight is determined according to the strength of the output signal of the left and right channel photosensitive elements, thereby further realizing the functions of automatically adjusting the air volume of the air conditioning outlets on the left and right sides of the vehicle.

[0046] In one possible implementation, Figure 1As shown, the light sensor device further includes a circuit board 1, which includes a first circuit module and a second circuit module arranged opposite to each other, the first photosensitive element 21 is electrically connected to the first circuit module, and the second photosensitive element 22 is electrically connected to the second circuit module.

[0047] Among them, the first photosensitive element 21 is used to receive light in the first channel and output an electrical signal through the first circuit module, and the second photosensitive element 22 is used to receive light in the second channel and output an electrical signal through the second circuit module. The signal output by the circuit board 1 is used to obtain radiation intensity data that is easy to observe, and to judge the sunlight radiation intensity at different azimuths and polar angles.

[0048] like Figure 2 As shown in , when the sunlight is projected downward from the center, the light receiving areas of the two photosensitive elements in the left and right channels are similar, and the output photocurrents are similar; Figure 3 As shown in FIG. 1 , when the sunlight deviates to the right, due to the existence of the light blocking portion 33, the light on the left is blocked, the light receiving area of ​​the right channel photosensitive element increases, the output photocurrent increases, and the light receiving area of ​​the left channel photosensitive element decreases, the output photocurrent decreases, so the right channel output signal is greater than the left side, so it can be judged that the position of the sunlight is on the right side; Figure 4 As shown, when the sunlight deviates to the left side, due to the existence of the light blocking part 33, the light on the right side is blocked, the light receiving area of ​​the left channel photosensitive element increases, the output photocurrent becomes larger, and the light receiving area of ​​the right channel photosensitive element decreases, the output photocurrent becomes smaller, so the right channel output signal is smaller than the left side, so it can be judged that the position of the sunlight is on the left side.

[0049] Among them, the photosensitive element is fixed on the PCB circuit board 1 by SMT patch technology, and there is no need to set a supporting base between the circuit board 1 and the photosensitive element, which simplifies the product structure, makes the light sensing device more compact as a whole, reduces the space required for installation, and at the same time improves production automation, improves production efficiency and reduces costs.

[0050] The first photosensitive element 21 and the second photosensitive element 22 are both SMD elements, and the two have the same model and similar performance. The internal chips of the photosensitive elements are chips with high sensitivity to the infrared light region.

[0051] The first photosensitive element 21 and the second photosensitive element 22 are placed symmetrically along the left and right ends of the circuit board 1, that is, the first circuit module and the second circuit module are symmetrically arranged, thereby ensuring the consistency of the left and right channel output signals. The filter 3 is a double material, consisting of a middle infrared-impermeable area and two infrared-permeable areas on both sides. The boundaries of the filter 3 at both ends are aligned with the centers of the left and right chips, respectively, to ensure the consistency of the left and right channel output signals.

[0052] Among them, the upper surface of the circuit board 1 is provided with a metal pad electrically connected to the photosensitive element, and the photosensitive element is a photodiode. The photosensitive diode is fixed to the metal pad on the upper surface of the circuit board 1 by solder paste using SMT patch technology to achieve electrical connection.

[0053] like Figure 1 As shown, the circuit board 1 is provided with a plug connector, and the lower surface of the circuit board 1 is provided with a metal pad electrically connected to the plug connector. The plug connector 5 is fixed on the metal pad of the circuit board 1 by reflow soldering to achieve electrical connection.

[0054] In one possible implementation, Figure 1 As shown, the light sensor device further includes a housing 4, which is made of an opaque material. The housing 4 is connected to the filter element 3 and is used to set the light receiving element 2 within the light receiving area.

[0055] The shell 4 may be made of a light-proof material or a material that is not transparent to infrared light, and is mainly used to cooperate with the filter element 3 to form a light-receiving area, namely, the first channel and the second channel.

[0056] Among them, the shell 4 can be made of opaque plastic products, opaque glass products or opaque rubber products, so that multiple photosensitive element covers can be set in the light receiving area, the filter 3 is set at the opening of the shell 4 and is located on the side of the light receiving element 2 for receiving light, and the photosensitive element receives the light passing through the transparent part.

[0057] The housing 4 and the filter element 3 may be fixedly connected or detachably connected, and may be connected by a threaded structure, a clamping structure, or a mortise and tenon structure.

[0058] In one possible implementation manner, the filter element 3 includes a light-incoming surface and a light-outgoing surface, and the light-incoming surface and the light-outgoing surface are arranged in parallel.

[0059] The light-incoming surface and the light-emitting surface of the light-transmitting portion may be parallel, and the incident light on one side of the light-transmitting portion and the emitting light on the other side of the light-transmitting portion have the same direction.

[0060] In one possible implementation, Figure 1 As shown, the filter element 3 includes a light-incoming surface and a light-outgoing surface, and the light-incoming surface and the light-outgoing surface are arranged at an angle to refract and converge the light into the channel of the light-receiving element 2 .

[0061] The light-incoming surface and the light-emitting surface of the light-transmitting portion may be arranged at an angle, and the incident light on one side of the light-transmitting portion is refracted by the light-transmitting portion to form an outgoing light that converges in the direction of the light-receiving element 2 .

[0062] Among them, the light-transmitting part can meet the needs of the photosensitive element to receive light, increase the range of light obtained, further reduce the size of the device, and reduce the occupied space.

[0063] In one possible implementation manner, the filter element 3 includes at least one convex surface, the light incident surface is a convex surface, and the filter element 3 is in the shape of a plano-convex lens or a bi-convex lens.

[0064] Among them, the light-incoming surface is convex toward the direction of sunlight, the first light-transmitting portion 31 refracts the light of the first channel and converges it onto the first photosensitive element 21, and the second light-transmitting portion 32 refracts the light of the second channel and converges it onto the second photosensitive element 22, thereby achieving the effect of converging parallel light and improving the accuracy and sensitivity of the light sensing device.

[0065] It is understandable that the size of the light-transmitting portion is specifically designed according to requirements to meet different needs.

[0066] A second aspect of the present invention provides an air conditioning system, comprising any one of the light sensor devices in the first aspect.

[0067] The air conditioning system has the effect of the above-mentioned light sensor and can be used in conjunction with the temperature sensor. The air conditioning detects the temperature and light conditions in the vehicle through the two together, can quickly detect the impact of light on the driver and passengers, improve the response speed of the air conditioning, and improve the intelligence of temperature control.

[0068] Among them, the light sensor device is connected to the control module of the air-conditioning system, and uses the changes in the blocking of sunlight by the double-material dust cover to cause changes in the output signals of the left and right channel photosensitive elements. Finally, the position of the sunlight is determined according to the strength of the output signals of the left and right channel photosensitive elements, thereby realizing functions such as automatic adjustment of the air volume of the air-conditioning outlets on the left and right sides of the vehicle.

[0069] When sunlight is projected downward from the center, the photocurrents output by the two photosensitive elements in the left and right channels are similar, and the air volume of the air-conditioning vents on the left and right sides of the vehicle can be automatically adjusted to be the same; when sunlight is biased to one side, due to the presence of the light-blocking portion 33, the light on one side is blocked, the photocurrent output by the photosensitive element on one side becomes smaller, and the photocurrent output by the photosensitive element on the other side becomes larger, so it can be determined that the position of the sunlight is on one side, and the air volume of the air-conditioning vent on one side can be automatically adjusted to be stronger than that on the other side.

[0070] A third aspect of the present invention provides a vehicle, comprising any one of the light sensor devices in the first aspect, or the air conditioning system in the second aspect.

[0071] The air-conditioning system can adjust the temperature at different positions in the vehicle through the light intensity and direction detected by the light sensor device. It can set different automatic air-conditioning temperatures for the driver and front passenger seats, and can also set different automatic air-conditioning temperatures for the front and rear passenger seats to correct the impact of light on different positions in the vehicle and improve the comfort of drivers and passengers in different positions. This light sensor device has strong directionality and can autonomously distinguish the radiation intensity in the left and right directions, thereby affecting the body temperature of the driver and front passenger in different situations.

[0072] The light sensor device is arranged inside the vehicle. Since sunlight passing through the windshield has a greater impact on the drivers and passengers in the main and front passenger seats, the light sensor device is arranged within the illumination range of light passing through the windshield 7, preferably on the inside of the vehicle's windshield or on the top of the dashboard. Setting the light sensor device on the windshield can better detect the lighting conditions and the impact of the light on the drivers and passengers.
