[0026] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a thorough understanding of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

[0029] Please refer to Figure 1 , Figure 1 a full-angle ambient light sensing device 100 provided for an embodiment of the present invention. The full-angle ambient light sensing device 100 can be used in an electronic device, and the electronic device may include a camera module, a flash module and a screen. The flash module controls the flash intensity according to the intensity of the ambient light detected by the full-angle ambient light sensing device 100. The electronic device can also control the brightness of the screen according to the intensity of the ambient light detected by the full-angle ambient light sensing device 100. In short, the ambient light illumination signal generated by the full-angle ambient light sensing device 100 can be used to adjust electronic products, or automatically turn on and off lighting devices, thereby achieving energy savings, extending the life of electronic products, and can also replace commercial illuminometers and be used to measure the actual illumination value of the external environment.

[0030] The full-angle ambient light sensing device 100 includes: a printed circuit board 10, a plurality of light sensing elements 20 electrically connected to the printed circuit board 10, and a housing 30 fixed to the printed circuit board 10. The housing 30 is used to encapsulate the plurality of light sensing elements 20 in the space formed by the printed circuit board 10 and the housing 30.

[0031] The light sensing element 20 can be a photoresistor, a photodiode, a phototransistor, or a photoelectric chip, etc. Each light sensing element 20 has a detection angle, and each light sensing element 20 detects the ambient illuminance in different directions. A plurality of the light sensing elements 20 can be fixedly arranged on one printed circuit board 10, or can be arranged on different printed circuit boards 10, but the different printed circuit boards 10 are fixed to the same substrate. When a plurality of the light sensing elements 20 are arranged on different printed circuit boards 10, the direction of the printed circuit board 10 can be arranged according to the direction that each light sensing element 20 needs to detect.

[0032] The housing 30 can be in various regular or irregular shapes such as square, arc-shaped, hexagonal, octagonal, or frustum-shaped. Please refer to Figure 1 , the housing 30 is square, and it includes a top plate 31 and four side plates 32 vertically connected to the top plate 31. Since it is a sectional view, only two side plates 32 are shown, but it does not affect the understanding.

[0033] Please refer to Figure 2 , the housing 30 included in the full-angle ambient light sensing device 100 is arc-shaped or semi-circular.

[0034] The housing 30 is used to prevent moisture, dust, etc. from affecting the quality and detection result of the light sensing element 20. To achieve the waterproof, dustproof, and anti-static effects of the full-angle ambient light sensing device 100.

[0035] The housing 30 is an opaque housing. The housing 30 is provided with openings 33 having the same number as the light sensing elements 20. Each light sensing element 20 is correspondingly provided with an opening 33 for light to pass through the opening 33, and the light sensing element 20 has a light sensing surface 22, and the light sensing surface 22 is arranged opposite to the opening 33. Each light sensing element 20 can detect the ambient illuminance through the corresponding opening 33.

[0036] The window 33 can be a regular shape such as circular, rectangular, arc-shaped, or trapezoidal. The aperture diameter of the window 33 is designed according to the detection angle range of the light sensing element 20, and the aperture diameter is equal to or less than the detection angle range of the light sensing element 20. That is, the range of the detection angle θ1 of each light sensing element 20 can be adjusted by adjusting the size of the window 33, and an appropriate number of the light sensing elements 20 can be reasonably arranged according to the range of the detection angle θ1, so that the full-angle ambient light sensing device senses the ambient light intensity within the range of the first vector angle θ of 0-180° and senses the ambient light intensity within the range of the second vector angle ψ of 0-360°. Among them, taking the full-angle ambient light sensing device 100 as the coordinate origin O, a three-dimensional polar coordinate system is established. Let the polar coordinates of any point A in the three-dimensional space be (r, θ, ψ), where r is the polar radius, that is, the distance from point A to the full-angle ambient light sensing device 100. The connection line between point A and the origin O is AO, and the connection line between the projection point A' of point A on the X-Y plane and the origin O is A'O. The first vector angle θ is the included angle between the straight line AO and the coordinate axis Z; the second vector angle ψ is the included angle between the straight line A'O and the X-axis or the Y-axis.

[0037] As Figure 1 shown, the top plate 31 is provided with a window 33 corresponding to the light sensing element 20, and each side plate 32 is also provided with a window 33 at the position corresponding to the light sensing element 20.

[0038] The housing 30 further includes a light-transmitting cover 34 having the same number as the windows 33 to close the windows 33, and the windows 33 are evenly distributed on the housing 30. In this way, the light sensing element 20 is located in the closed space composed of the housing 30, the light-transmitting cover 34, and the printed circuit board 10, but the ambient light can pass through the light-transmitting cover 34 and be detected by the light sensing element 20.

[0039] Please refer to Figure 3 FIG. 5 and FIG. 6. In this embodiment, the number of the light sensing elements 20 is 5, and all are arranged on the same printed circuit board 10.

[0040] In other embodiments, the number of the light sensing elements 20 can be more or less than 5, as long as the sum of the detection angles of the surrounding light sensing elements 20 in the X-Y plane is 360. For example, when the number of the light sensing elements 20 is 4, one is arranged in the center and three are arranged on the circumference, and the corresponding windows and sizes are set according to the positions of the light sensing elements 20 on the circumference; when the number of the light sensing elements 20 is 6, one is arranged in the center and five are arranged on the circumference.

[0041] Regardless of the number of the light sensing elements 20, they are all located on the circumference of the same circle and evenly distributed on the circumference, so that the ambient light illuminance within the range of the first vector angle θ of 0 - 180° and the ambient light illuminance within the range of the second vector angle ψ of 0 - 360° can be detected by the light sensing elements 20 evenly distributed on the circumference.

[0042] The included angles between the multiple light sensing elements 20 on the circumference can be equal or unequal, which is determined by the detection range of each light sensing element 20. Preferably, the included angles between the light sensing elements 20 are equal.

[0043] In this embodiment, one light sensing element 20 is respectively arranged at the four directions of east, south, west, and north of the printed circuit board 10 and at the central position of the printed circuit board. The light sensing elements at the four directions of east, south, west, and north are located on the circumference of the same circle, and another light sensing element is located at the center of the circle determined by the light sensing elements at the four directions of east, south, west, and north. The five light sensing elements 20 can respectively detect the ambient light illuminance from the east, south, west, north, and directly above.

[0044] Please refer to Figure 1 and FIGS. 5 and 6. In this embodiment, the detection angles of the light sensing elements at the four directions of east, south, west, and north in the X-Z plane or the Y-Z plane are (90 - θ1); the detection angle of the central light sensing element in the X-Z plane or the Y-Z plane is 2θ1. The detection angles of the light sensing elements 20 at the four directions of east, south, west, and north in the X-Y plane are ψ1, ψ2, ψ3, ψ4 respectively; ψ1, ψ2, ψ3, ψ4 satisfy ψ1 + ψ2 + ψ3 + ψ4 = 360°. In this way, the 360° full angle of the ψ angle is jointly divided by the light sensing elements 20 at the four directions of east, west, south, and north, so that the ambient light at any point in space can be sensed by one of the multiple light sensing elements 20 included in the full angle ambient light sensing device 100. Where 0° < θ1 < 90°; 0° < ψ1, ψ2, ψ3, ψ4 < 180°.

[0045] Preferably, 40° ≤ θ1 ≤ 45°; more preferably, θ1 = 45°.

[0046] Preferably, ψ1 = ψ2 = ψ3 = ψ4 = 90°.

[0047] Please specifically refer to Figure 5A and Figure 6A , the detection angle of the central light sensing element 20 in the X-Y plane is 360°.

[0048] Thus, the detection angle of the photosensing element 20 centered on the first full-angle range β1 that the full-angle ambient light sensing device 100 can sense is the sum of the detection angles of the photosensing elements 20 at both ends, that is, β1 = 2θ1 + 2(90 - θ1) = 180°. Therefore, the full-angle ambient light sensing device senses the ambient light intensity when the first vector angle θ is in the range of 0 - 180°.

[0049] The second full-angle range β2 that the full-angle ambient light sensing device 100 can sense is the sum of the detection angles of the photosensing elements 20 in the four directions of east, south, west, and north. When ψ1 = ψ2 = ψ3 = ψ4 = 90°, that is, β2 = ψ1 + ψ2 + ψ3 + ψ4 = 360°. Therefore, the full-angle ambient light sensing device 100 senses the ambient light intensity when the second vector angle ψ is in the range of 0 - 360°.

[0050] Due to the light-tight property of the housing 30, the ambient light in the area E between two adjacent photosensing elements 20 cannot be detected by the photosensing element 20 due to the shielding of the housing 30, forming a distortion area where the "local angle" cannot be detected. However, in the far-field case, that is, when the distance between the light source and the full-angle ambient light sensing device 100 is infinitely far, the distortion area where the "local angle" cannot be detected in the near field can be almost ignored, thus enabling full-angle detection.

[0051] Please refer to Figures 5A - 5C This is the simulated light intensity detected by each photosensing element 20 within its respective detection angle range when the window 33 of the housing 30 included in the full-angle ambient light sensing device 100 is a rectangular aperture.

[0052] Among them, Figure 5A This is a top view of the simulated light intensity detected by each photosensing element 20 included in the full-angle ambient light sensing device 100 within its respective detection angle range. Figure 5A The 4 fan-shaped areas around represent the first ambient light intensity ranges 21 that the photosensing elements 20 in the four directions of east, south, west, and north can detect respectively, and the central quadrilateral area represents the second ambient light intensity range 23 that the central photosensing element 20 can detect.

[0053] Figure 5B This is a side view of the simulated light intensity detected by each photosensing element 20 within its respective detection angle range.

[0054] Figure 5C This is a 3D view of the simulated ambient light intensity detected by each photosensing element 20 within its respective detection angle range.

[0055] Such as Figure 5AAs shown in the figure, starting from the east and rotating clockwise, that is, the ambient light within the range of 0 - 45° can be detected by the east-facing ambient light sensing element 20, the ambient light within the range of 45° - 135° can be detected by the north-facing ambient light sensing element 20; the ambient light within the range of 135° - 225° can be detected by the west-facing ambient light sensing element 20; the ambient light within the range of 225° - 315° can be detected by the south-facing ambient light sensing element 20; the ambient light within the range of 315° - 360° can be detected by the east-facing ambient light sensing element 20.

[0056] Thus, the ambient light intensity within the range of 0 - 180° of the first vector angle θ and the ambient light intensity within the range of 0 - 360° of the sensed second vector angle ψ can both be detected by the full-angle ambient light sensing device 100.

[0057] Please refer to Figures 6A - 6C For the case where the opening 33 of the housing 30 included in the full-angle ambient light sensing device 100 is a circular aperture, it shows the light intensity detected by each light sensing element 20 within its respective detection angle range.

[0058] Among them, Figure 6A It is a top view of the light intensity detected by each light sensing element 20 within its respective detection angle range.

[0059] Figure 6B It is a side view of the light intensity detected by each light sensing element 20 within its respective detection angle range.

[0060] Figure 6C It is a 3D view of the light intensity detected by each light sensing element 20 within its respective detection angle range. Figure 6C The detection range of the central light sensing element 20 shown in is conical. The detection angle of this light sensing element 20 is a cone angle. The three-dimensional concept of the cone angle is formed by rotating the ±θ1 angle in the X-Y plane (or Y-Z plane) 180 degrees around the Z axis. Therefore, by rotating 180 degrees around the Z axis, the detection range of the central light sensing element 20 can be obtained, that is, ψ that can be detected in the X-Y plane is 360 degrees. So when the cone is projected onto the X-Y plane (top view), its ψ is 360 degrees (that is, the ±θ1 angle combined is 360 degrees after rotating 180 degrees around the Z axis).

[0061] In summary, the ambient light intensity within the range of 0 - 180° of the first vector angle θ and the ambient light intensity within the range of 0 - 360° of the sensed second vector angle ψ can both be detected by the full-angle ambient light sensing device 100.

[0062] In this embodiment, the full-angle ambient light sensing device 100 also includes a data processing unit 40, which is electrically connected to the multiple light sensing elements 20 to obtain the ambient light illumination detected by each light sensing element 20, and processes the obtained multiple ambient light illuminations to output the detection results of the full-angle ambient light sensing device 100.

[0063] The detection result of the full-angle ambient light sensing device 100 may be the sum of the light intensities detected by the plurality of light sensing elements 20 .

[0064] The detection result of the full-angle ambient light sensing device 100 may be the maximum value or the minimum value of the light illumination respectively detected by the plurality of light sensing elements 20 .

[0065] The detection result of the full-angle ambient light sensing device 100 may also be an average value of the light intensities detected by the plurality of light sensing elements 20 .

[0066] Each light sensing element 20 can detect light intensity within a certain range, so that the sum of the detection angles β1 of multiple light sensing elements 20 in the XZ and YZ spatial ranges reaches 180 degrees and the detection angle β2 in the XY spatial range reaches a detection range of 360 degrees. Therefore, the electronic device can also adjust the brightness of the area where it is located according to the ambient light illumination value detected by each light sensing element 20, thereby realizing full-angle ambient light detection and high-precision detection.

[0067] In summary, the full-angle ambient light sensing device 100 provided by the present invention includes a printed circuit board 10 and a plurality of light sensing elements 20. Since the plurality of light sensing elements 20 are electrically connected to the printed circuit board 10, each of the light sensing elements 20 can be configured to detect ambient light illumination in different directions. Therefore, we can select a suitable number of light sensing elements 20 through the detection angle range of the light sensing element 20 to achieve multi-directional, full-angle range light illumination detection. By expanding the detection range of ambient light illumination, the ambient light monitoring accuracy is improved to achieve a full-angle angle detection function similar to that of a commercial illuminance meter.
