[0039] 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 present invention more clear and specific to those skilled in the art, the implementation methods described below are not limited to this. The present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0040] In the present invention, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance; the term "plurality" refers to two or more, unless otherwise clearly defined. The terms "installed", "connected", "connected", "fixed", etc. 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 specific circumstances.

[0041] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by terms such as “upper”, “lower”, “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.

[0042] like Figure 1-Figure 3 As shown, an embodiment of the first aspect of the present disclosure provides a light sensor, including: a light blocking plate 5, a first light receiving element 3 and a second light receiving element 4, the light blocking plate 5 is used to divide the light receiving area into a first area and a second area, the first light receiving element 3 is arranged in the first area, and is used to obtain light data in the first area; the second light receiving element 4 is arranged in the second area, and is used to obtain light data in the second area.

[0043] The present invention includes a light blocking plate 5 and a plurality of light receiving elements. The light blocking plate 5 is used to divide a plurality of light receiving areas to prevent the light receiving elements from being disturbed by light from other light receiving areas, so that the light receiving elements can obtain the illumination data of the light receiving areas separately. The present invention arranges a plurality of light receiving elements, and enables the plurality of light receiving elements to obtain illumination data in different areas through the light blocking plate 5. According to the arrangement of the plurality of areas and the difference in the illumination data obtained, it is convenient to further judge the intensity and direction of the illumination.

[0044] like Figure 1-Figure 3As shown, the first light receiving element 3 and the second light receiving element 4 in this embodiment are symmetrically arranged, and the light blocking plate 5 divides the light receiving area into a first area and a second area, thereby increasing the directional distinction. Through the separation of the opaque light blocking plate 5, the first light receiving element 3 can only obtain the illumination data in the first area, and the second light receiving element 4 can only obtain the illumination data in the second area. 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.

[0045] like Figure 3 As shown in the figure, the arrow direction is the direction of the vehicle head, the x and z planes are the horizontal planes, and the light sensor is set on the front glass of the vehicle and forms a certain angle with the normal direction of the horizontal plane. The normal direction is defined as the positive direction of the y axis, the upward component is the positive direction of the z axis, and the directions of the azimuth angle and the polar angle are as follows: Figure 3 as shown in .

[0046] When the radiation intensity received by the first light receiving element 3 is greater than the radiation intensity received by the second light receiving element 4, the sun is located in the direction of the first area of ​​the light sensor, that is, the azimuth is closer to 0°, and the polar angle is closer to -90°; when the radiation intensity received by the first light receiving element 3 is less than the radiation intensity received by the second light receiving element 4, the sun is located in the direction of the second area of ​​the light sensor, that is, the azimuth is closer to 0°, and the polar angle is closer to 90°; when the radiation intensity received by the first light receiving element 3 is close to the radiation intensity received by the second light receiving element 4, the sun is located near the intersection of the first area and the second area of ​​the light sensor, that is, the azimuth is closer to 90° / -90°, and the polar angle is closer to 0°; therefore, the approximate azimuth of the sun can be determined by the difference in the light radiation intensity obtained by the first light receiving element 3 and the fourth light receiving element 4.

[0047] When the difference between the radiation intensity received by the first light receiving element 3 and the radiation intensity received by the second light receiving element 4 is large, the angle between the sun and the plane perpendicular to the line connecting the first light receiving element 3 and the second light receiving element 4 and passing through the midpoint of the line is large, that is, the polar angle is closer to -90° / 90°; similarly, when the difference between the radiation intensity received by the first light receiving element 3 and the radiation intensity received by the second light receiving element 4 is small, the angle between the sun and the plane perpendicular to the line connecting the first light receiving element 3 and the second light receiving element 4 and passing through the midpoint of the line is small, that is, the polar angle is closer to 0°; the difference in the illumination radiation intensity obtained by the first light receiving element 3 and the fourth light receiving element 4 can be used to determine the approximate polar angle of the sun.

[0048] like Figure 5-Figure 9As shown, the horizontal axis represents the polar angle gradually changing from -90° to +90°, and the vertical axis represents the normalized radiation intensity received by the first light receiving element 3 from the light source, in W; the light distribution summary curve of the radiation intensity of the second light receiving element 4 changing with the polar angle is symmetrical with the light distribution summary curve of the radiation intensity of the first light receiving element 3 changing with the polar angle about the polar angle of 0°. Figure 5 It can be seen from the radiation intensity change curve at azimuth angles of 0°, 45°, 90°, and 135° that the radiation intensity has a small degree of left-right flipping overlap relative to the polar angle of 0°. It has strong directionality in the azimuth planes of 0°, 45°, 90°, and 135°. The peak radiation intensity corresponds to the solar noon azimuth, the half-peak angle is approximately large, and has a good angular reception range.

[0049] In one possible implementation, Figure 4 As shown, the light sensor also includes a third light receiving element 9 and a fourth light receiving element 10. The third light receiving element 9 is arranged in the third area to obtain the light data in the third area, and the fourth light receiving element 10 is arranged in the fourth area to obtain the light data in the fourth area; wherein the first area, the second area, the third area and the fourth area are separated by a light blocking plate 5.

[0050] like Figure 4 As shown, it can be understood that the light-receiving area is divided into the first area, the second area, the third area and the fourth area by the light-blocking plate 5. The cross section of the light-blocking plate 5 can be in the shape of a cross. A light-receiving element is separately provided in each area. Preferably, the angle between two adjacent light-receiving elements is 90°. The first light-receiving element 3 can only obtain the light data in the first area, the second light-receiving element 4 can only obtain the light data in the second area, the third light-receiving element 9 can only obtain the light data in the third area, and the fourth light-receiving element 10 can only obtain the light data in the fourth area. According to the comparison of the radiation intensity and the difference of the radiation intensity between the four groups of light data, the polar angle and azimuth of the light can be judged more clearly, and then the position of the sun relative to the light sensor can be judged.

[0051] It can be understood that, in the first aspect, when the radiation intensity received by the first light receiving element 3 is greater than the radiation intensity received by the second light receiving element 4, the third light receiving element 9 and the fourth light receiving element 10, the sun is located in the direction of the first area of ​​the light sensor, that is, the azimuth angle range is (0°, 90°), and the polar angle range is (-90°, 0°); in the second aspect, when the radiation intensity received by the second light receiving element 4 is greater than the radiation intensity received by the third light receiving element 9, the sun is located in the first area of ​​the light sensor and closer to the second area, that is, the azimuth angle range is (45°, 90°), and the polar angle range is (-90°, 0°); in the third aspect, In the first and fourth aspects, the range of polar angles can be further narrowed according to the difference between the radiation intensity received by the first light receiving element 3 and the radiation intensity received by the second light receiving element 4. The larger the difference, the closer the azimuth is to 45°, and the smaller the difference, the closer the azimuth is to 90°. In the first and fourth aspects, the range of polar angles can be further narrowed according to the difference between the radiation intensity received by the first light receiving element 3 and the radiation intensity received by the second light receiving element 4, the third light receiving element 9 and the fourth light receiving element 10. The larger the difference, the closer the sun is to the horizontal direction of the light sensor itself, and the smaller the difference, the closer the sun is to the normal direction of the light sensor itself. Similarly, the azimuth and polar angle range of the sun can be further determined according to the comparison of the size and difference of the radiation intensity received by the first light receiving element 3, the second light receiving element 4, the third light receiving element 9 and the fourth light receiving element 10.

[0052] In one possible implementation, the light sensor also includes a circuit board 6 and a housing 2, the first light receiving element 3 and the second light receiving element 4 are arranged on the circuit board 6, and the housing 2 is arranged on the circuit board 6 and is made of an opaque material to cover the first light receiving element 3 and the second light receiving element 4 within the light receiving area.

[0053] like Figure 1 and Figure 2 As shown, by arranging the light receiving element on the circuit board 6, the light receiving element receives sunlight, and obtains radiation intensity data that is easy to observe through the signal output by the circuit board to judge the sunlight radiation intensity at different azimuth angles and different polar angles.

[0054] The housing 2 can be made of opaque plastic, opaque glass or opaque rubber, etc., so that multiple light receiving elements can be covered inside, and the housing 2 and the light blocking plate 5 divide the light receiving area where the light receiving elements can receive light.

[0055] In one possible implementation, when the light sensor further includes a third light receiving element and a fourth light receiving element, the third light receiving element and the fourth light receiving element are both disposed on the circuit board 6, and the housing 2 sets the third light receiving element and the fourth light receiving element within the light receiving area.

[0056] It is understandable that if Figure 1-Figure 4 As shown, the shape of the housing 2 can be a prism, a cylinder, etc., and an open end is provided on the housing 2, and the light receiving element receives the light that passes through the open end and irradiates the light receiving element.

[0057] In one possible implementation, the light sensor further includes a lens 1, which is connected to the housing 2 and covers the light receiving area; wherein the lens 1 is in the shape of a truncated cone or a prism, and the area of ​​the top surface of the lens 1 is larger than the area of ​​the bottom surface.

[0058] like Figure 1 and Figure 2 As shown, the lens 1 is arranged at the open end of the housing 2 and is located on the light receiving surface side of the light receiving element. The light receiving element receives the light passing through the lens 1, and converges on the upper surface of the light receiving chip 4 after refraction by the lens 1. The lens is arranged in a truncated cone or prism shape with a wide top and a narrow bottom to increase the receiving angle of the light during total reflection, and can increase the range of light received by the light receiving element.

[0059] It can be understood that the shape of the lens 1 in the area corresponding to each light-receiving element is symmetrical, which ensures the symmetry of each sub-light-receiving area and increases the distinguishability of the light direction.

[0060] In one possible implementation, the lens 1 is an integrally formed structure, the lens 1 is located on the side of the first light receiving element 3 and the second light receiving element 4 for receiving light, and covers the first area and the second area; wherein the lens 1 includes a light incident surface, a light emitting surface and a first side surface, the light incident surface and the light emitting surface are parallel to the light receiving surface of the light receiving element, and the angle of the first side surface relative to the light receiving surface is 20° to 40°.

[0061] It can be understood that the lens 1 can be an integrally formed structure, and a groove for accommodating the light blocking plate 5 is opened inside the lens 1. One end of the light blocking plate 5 can extend to the circuit board. While being able to block the interaction of light between the sub-light receiving areas, the light blocking plate 5 can also leave a certain gap with the circuit board.

[0062] In one possible implementation, the lens 1 is a split structure, and the lens 1 includes a first mirror body and a second mirror body, the first mirror body is located on the side of the first light receiving element 3 for receiving light and covers the first area, and the second mirror body is located on the side of the second light receiving element 4 for receiving light and covers the second area; wherein, the lens 1 includes a light incident surface, a light emitting surface, a first side surface and a second side surface, the light incident surface and the light emitting surface are parallel to the light receiving surface of the light receiving element, and the angle of the first side surface relative to the light receiving surface is 20° to 40°.

[0063] It can be understood that the lens 1 can be a split structure, and each sub-light receiving area where the light receiving element is located is provided with a mirror body, and the multiple mirror bodies are blocked by light blocking plates 5 to block light from entering other sub-light receiving areas.

[0064] In one possible implementation, at least a portion of the light blocking plate 5 is located inside the lens 1; or, when the lens 1 includes a first lens body and a second lens body, the light blocking plate 5 is located between the first lens body and the second lens body.

[0065] The angle between the side of the lens 1 close to the housing 2 and the light receiving surface of the light receiving element is preferably 20° to 40°, and the thickness of the lens 1 is preferably 2 to 6 mm. The light passing through the lens 1 converges on the light receiving surface of the light receiving element, which can meet the needs of the light receiving element to receive light, increase the range of light obtained, and further reduce the size of the device.

[0066] When the temperature inside the car is the same, the lighting conditions will also have a great impact on the perceived comfort of the driver and passengers. When the vehicle is exposed to the sun or the sun is blocked, the driver and passengers can quickly feel the change, but the effect of the lighting conditions on the temperature inside the car takes a certain amount of time, resulting in the air conditioner being unable to adjust the temperature according to the actual feelings of the driver and passengers, and the comfort of the driver and passengers is poor. When the car is exposed to the sun with strong light radiation, the strong light shines on the body of the driver and passengers, and the perceived temperature of the driver and passengers rises rapidly; when the sun is blocked, the perceived temperature of the driver and passengers drops rapidly, and then the change in light intensity has little effect on the actual temperature in the car in a short time. The air conditioner cannot adjust the air outlet temperature and air volume in time according to the perceived temperature of the driver and passengers, and the direction of light will also affect the perceived temperature of the driver and passengers in different positions of the vehicle, that is, due to the direction of light, the perceived temperature of the people in the main and co-driver positions will also be different. The existing vehicle air conditioner only uses the temperature sensor to obtain the actual temperature in the vehicle for temperature adjustment, and cannot perform intelligent temperature adjustment according to the change in light intensity and the influence of light direction on the perceived temperature of the driver and passengers.

[0067] An embodiment of the second aspect of the present disclosure provides an air conditioning system, comprising any one of the above-mentioned light sensors.

[0068] 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.

[0069] The air conditioner can adjust the temperature at different positions in the vehicle through the light intensity and direction detected by the light sensor. Different automatic air-conditioning temperatures can be set for the driver and front passenger seats, and different automatic air-conditioning temperatures can be set for the front and rear passenger seats to correct the impact of light on different positions in the car and improve the comfort of drivers and passengers in different positions. This light sensor has strong directionality and can autonomously distinguish the radiation intensity from the left and right directions, thereby affecting the perceived temperature of the driver and front passenger in different situations.

[0070] An embodiment of the third aspect of the present disclosure provides a vehicle, comprising any one of the above-mentioned light sensors or the above-mentioned air-conditioning system.

[0071] like Figure 2 and Figure 3 As shown, the light sensor is arranged inside the vehicle. Since sunlight passing through the windshield 7 has a greater impact on the drivers and passengers in the main and front passenger seats, the light sensor is arranged within the illumination range of light passing through the windshield 7, preferably on the inside of the windshield 7 of the vehicle or on the top of the dashboard. Setting the light sensor on the windshield 7 can better detect the lighting conditions and the impact of light on the drivers and passengers.

[0072] In specific implementation, the light sensor can be connected to the windshield or instrument panel through a connector such as a suction cup, a bolt, or an adhesive. Figure 2 As shown, if the connecting piece is located in the light receiving area of ​​the light receiving element, the connecting piece needs to be made of a light-transmitting material, such as a silicone layer 8. The silicone layer 8 is pasted and fixed to the vehicle glass after the product is packaged.
