Technical Field
[0001] This application belongs to the technical field of intelligent security products, and particularly relates to a supplementary lighting device and a monitoring device. Background Art
[0002] The supplementary lighting device is an important part of the monitoring device. Its main function is to provide necessary supplementary lighting in an environment with insufficient light, so that the monitoring device can capture clear images. With the progress of technology, the requirements for the quality of the images captured by the monitoring device are getting higher and higher, and accordingly, the requirements for the supplementary lighting effect of the supplementary lighting device are also getting higher and higher.
[0003] However, traditional supplementary lighting devices usually use a single supplementary light to completely cover the monitoring field of view, that is, use a single supplementary light to perform overall supplementary lighting on all target areas to be monitored. Although this design can meet the basic supplementary lighting requirements of the monitoring device, the supplementary lighting requirements corresponding to different target areas are often different, resulting in a poor supplementary lighting effect of the supplementary lighting device. Summary of the Utility Model

The light source component includes a light source module and a lens. The incident light surface of the lens faces the light source module, and the lens of at least one of the light source components is a polarizing lens, so that the light of each light source component is respectively directed to different target areas.
[0006] In a second aspect, the embodiments of this application further provide a monitoring device, which includes the above-mentioned supplementary lighting device.
[0007] In the embodiments of this application, the supplementary lighting device includes at least two light source components, and the light of each light source component is respectively directed to different target areas. In this way, each target area is supplemented with light by different light source components respectively, so that zonal supplementary lighting can be performed on each target area according to the supplementary lighting requirements of each target area. In this way, the supplementary lighting intensity of each target area can be adapted to its own supplementary lighting requirements, so that the supplementary lighting effect of the supplementary lighting device is better. In addition, with such a setting, the user can supplement light for one target area or multiple target areas separately according to actual needs, thereby reducing energy consumption and making the supplementary lighting device applicable to more scenarios, and this can also make the control of the supplementary lighting device more flexible.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0020] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.
[0021] The following will combine the accompanying drawings to detail the light supplement device and the monitoring device provided by the embodiments of this application through specific embodiments and their application scenarios.
[0022] Please refer to Figures 1 to 6 As shown, in the embodiment of this application, a light supplement device is provided, including: at least two light source components 200, and the specific number of the light source components 200 is determined according to actual needs. The light source component 200 includes a light source module and a lens 210. The light incident surface of the lens 210 faces the light source module, and the lens of at least one light source component 200 is a polarizing lens, so that the light of each light source component 200 is respectively emitted to different target areas 310. The polarizing lens can guide the light 400 to propagate along a preset direction, so that the light 400 can be more accurately emitted to the target area 310. During the specific use process, the optical axis of the polarizing lens is deflected relative to the optical axis of the corresponding light source module, and the light 400 passes through the polarizing lens and shoots towards the target area 310.
[0023] In the embodiment of this application, the light supplement device includes at least two light source components 200, and the light 400 of each light source component 200 is respectively emitted to different target areas 310. In this way, each target area 310 is supplemented with light by different light source components 200 respectively, so that each target area 310 can be supplemented with light in a partitioned manner according to the light supplement requirements of each target area 310. In this way, the light supplement intensity of each target area 310 can be adapted to its own light supplement requirements, so that the light supplement effect of the light supplement device is better. In addition, with such a setting, the user can supplement light to one target area 310 or multiple target areas 310 separately according to actual needs, so as to reduce energy consumption and make the light supplement device applicable to more scenarios, and this can make the control of the light supplement device more flexible.
[0024] In another embodiment, refer to Figure 2 and Figure 3As shown, at least two light source components 200 include a first light source component 200a and a second light source component 200b. The lens 210 of the first light source component 200a is a first lens 210a, and the lens 210 of the second light source component 200b is a second lens 210b. Both the first lens 210a and the second lens 210b are polarizing lenses, and the first lens 210a and the second lens 210b deflect the light rays 400 in opposite directions respectively. With such an arrangement, the light rays 400 emitted from the first lens 210a and the light rays 400 emitted from the second lens 210b can cover a relatively large area as a whole, so that the light supplement device can supplement light to a relatively large area.
[0025] In addition, with such an arrangement, it is possible to prevent a relatively large overlapping portion between the target area 310 corresponding to the first light source component 200a and the target area 310 corresponding to the second light source component 200b, so as to prevent the brightness of the overlapping portion between the target area 310 corresponding to the first light source component 200a and the target area 310 corresponding to the second light source component 200b from being too high, and further make the light supplement uniformity of the light supplement device better.
[0026] For the convenience of description, the light source module of the first light source component 200a can be defined as the first light source module. Correspondingly, the optical axis of the first light source module can be defined as the first optical axis. The light source module of the second light source component 200b can be defined as the second light source module. Correspondingly, the optical axis of the second light source module can be defined as the second optical axis. The first optical axis and the second optical axis are, for example, parallel, and the first lens 210a deflects the light rays 400, for example, toward the side of the first optical axis away from the second optical axis, and the second lens 210b deflects the light rays 400, for example, toward the side of the second optical axis away from the first optical axis. And along the direction of the first optical axis extending from the position close to the first light source module to the position away from the first light source module, the distance between at least some of the light rays 400 emitted from the first lens 210a and the first optical axis gradually increases, for example. Along the direction of the second optical axis extending from the position close to the second light source module to the position away from the second light source module, the distance between at least some of the light rays 400 emitted from the second lens 210b and the second optical axis gradually increases, for example.
[0027] In other alternative embodiments, the first lens 210a and the second lens 210b can also deflect the light rays 400 in the same direction respectively.
[0028] In a further embodiment, refer to Figure 3As shown, at least two light source components 200 further include a third light source component 200c. The target areas 310 towards which the light rays 400 emitted by the first light source component 200a, the second light source component 200b, and the third light source component 200c are directed are respectively a first target area 310a, a second target area 310b, and a third target area 310c. The third target area 310c is connected to both the part of the first target area 310a close to the second target area 310b and the part of the second target area 310b close to the first target area 310a. With such an arrangement, the third light source component 200c can supplement the illumination of the area between the first target area 310a and the second target area 310b. In this way, the area between the first target area 310a and the second target area 310b has a dedicated light source component 200 for supplementary lighting, thereby improving the supplementary lighting effect of the area between the first target area 310a and the second target area 310b. In addition, when the first target area 310a and the second target area 310b are spaced apart, the solution adopted in this embodiment can prevent the area between the first target area 310a and the second target area 310b from being too dark relative to the first target area 310a and the second target area 310b.
[0029] As a specific implementation manner, the first light source component 200a, the second light source component 200b, and the third light source component 200c are, for example, arranged side by side. The optical axis of the lens 210 of the third light source component 200c coincides with the optical axis of the lens 210 of the third light source component 200c, and the lens 210 of the third light source component 200c is, for example, rotationally symmetric about its own optical axis.
[0030] In other alternative embodiments, the third light source component 200c may not be included.
[0031] Further, referring to Figure 5As shown, the third target area 310c coincides with the part of the first target area 310a close to the second target area 310b and forms a first overlapping area 320. The third target area 310c coincides with the part of the second target area 310b close to the first target area 310a and forms a second overlapping area 330. At least one of the surface of the first lens 210a facing the third light source assembly 200c and the surface of the second lens 210b facing the third light source assembly 200c is provided with a recess; and / or, at least one of the surface of the first lens 210a facing the third light source assembly 200c and the surface of the second lens 210b facing the third light source assembly 200c is provided with a protrusion. For example, recesses can be provided on both the surface of the first lens 210a facing the third light source assembly 200c and the surface of the second lens 210b facing the third light source assembly 200c. Or, protrusions can be provided on both the surface of the first lens 210a facing the third light source assembly 200c and the surface of the second lens 210b facing the third light source assembly 200c. Or, a recess can be provided on one of the surface of the first lens 210a facing the third light source assembly 200c and the surface of the second lens 210b facing the third light source assembly 200c, and a protrusion can be provided on the other.
[0032] It can be understood that the first overlapping area 320 is formed by the overlap of the first target area 310a and the third target area 310c, and the second overlapping area 330 is formed by the overlap of the second target area 310b and the third target area 310c. Compared with the non-overlapping parts of the first target area 310a, the second target area 310b, and the third target area 310c respectively, the brightness of the first overlapping area 320 and the second overlapping area 330 may be greater or smaller.
[0033] In this embodiment, by providing a recess, the number of light rays 400 directed to the corresponding area can be reduced. On the contrary, by providing a protrusion, the number of light rays 400 directed to the corresponding area can be increased. And the more the number of light rays 400, the greater the brightness. On the contrary, the fewer the number of light rays 400, the smaller the brightness. Thus, the solution adopted in this embodiment can increase or decrease the brightness of the first overlapping area 320 and the second overlapping area 330. In this way, the user can flexibly adjust the brightness of the first overlapping area 320 and the second overlapping area 330, thereby preventing the situation where the brightness of the first overlapping area 320 and the second overlapping area 330 is too large or too small compared with the non-overlapping parts of the first target area 310a, the second target area 310b, and the third target area 310c.
[0034] In other alternative embodiments, the above-mentioned recesses and protrusions may not be provided.
[0035] In an alternative embodiment, the above-described recessed portions may be formed on the surface of the first lens 210a facing the third light source module 200c and the surface of the second lens 210b facing the third light source module 200c by using a texturing process.
[0036] In another embodiment, referring to Figure 1 As shown, the curvature of the surface of the first lens 210a facing the second lens 210b is greater than the curvature of the surface of the first lens 210a facing away from the second lens 210b, so that the light rays 400 are deflected in a direction away from the second lens 210b. The curvature of the surface of the second lens 210b facing the first lens 210a is greater than the curvature of the surface of the second lens 210b facing away from the first lens 210a, so that the light rays 400 are deflected in a direction away from the first lens 210a. With such a setting, the surface of the first lens 210a facing the second lens 210b, the surface of the first lens 210a facing away from the second lens 210b, the surface of the second lens 210b facing the first lens 210a, and the surface of the second lens 210b facing away from the first lens 210a are all arc surfaces. The light output from the arc surfaces is relatively uniform, so that the light supplementing effect of the light supplementing device is better. Moreover, when the surfaces described herein satisfy the above-described curvature relationship, the light rays 400 can be irradiated onto the target area 310 more accurately and uniformly.
[0037] Referring to Figure 1 As shown, the surface of the first lens 210a facing the second lens 210b and the surface of the first lens 210a facing away from the second lens 210b are, for example, the first surface 211 and the second surface 212 of the first lens 210a respectively, and the surface of the second lens 210b facing the first lens 210a and the surface of the second lens 210b facing away from the first lens 210a are, for example, the third surface 213 and the fourth surface 214 of the second lens 210b respectively.
[0038] In other alternative embodiments, the surface of the first lens 210a facing the second lens 210b, the surface of the first lens 210a facing away from the second lens 210b, the surface of the second lens 210b facing the first lens 210a, and the surface of the second lens 210b facing away from the first lens 210a may also all be flat surfaces.
[0039] The specific shape of the lens 210 is determined according to the light supplementing requirements. Specifically, the energy mapping relationship of the light source module is, for example, as Figure 6 shown. It should be noted that Figure 6 only the first quadrant is shown. Referring to Figure 6As shown in the figure, the radiant flux within a certain solid angle dΩ with the angle of the light ray 400 being (u, v) enters a certain rectangular area dA within the target surface after being projected by the free-form surface optical system. Here, u represents the angle between the light ray 400 and the x-axis, and v represents the angle between the projection of the light ray 400 in the yoz plane and the z-axis. The light intensity distribution I(u, v) = I0sin(u)cos(v), where I0 is the light intensity in the direction parallel to the optical axis of the light source module. The light rays 400 with the same u angle fall on a straight line with the same x value on the target surface, and the light rays 400 with the same v angle fall on a straight line with the same y value on the target surface. Combining with the law of conservation of energy, we have:
[0040] ∫∫I0sin 2 (u)cos(v)dudv = ∫∫Edxdy (1)
[0041] First, determine the corresponding relationship between u and x:
[0042] I0∫0 π / 2 cos(v)dv∫ u π / 2 sin 2 (u)du = ExL y (2)
[0043] x = I0(π - (2u - sin(2u))) / 4EL y (3)
[0044] Similarly, we have
[0045] I0∫0 π / 2 sin 2 (u)du∫0 V cos(v)dv = EyL x (4)
[0046] y = πI0sin(v) / 4EL x (5)
[0047] In this way, through equations (3) and (5), a one-to-one correspondence between the angle (u, v) of the light ray 400 of the light source module and the coordinates (x, y) of the target surface in this energy mapping relationship is established. On this basis, first calculate a generatrix at u0, and then take each point on the generatrix as the starting point to obtain v i , and finally import all the curves into Creo or SolidWorks and convert them into solids to obtain the lens 210 with the required shape.
[0048] In the specific use process, the area that needs to be filled with light can be divided into at least two target areas 310 first, and then according to the light filling requirements of each target area 310, the shape of the lens 210 of the light source component 200 corresponding to each target area 310 is designed respectively.
[0049] It should be noted that the detailed shape of the lens 210 in the embodiments of the present application is not limited. For example, the shape of each lens 210 of the supplementary light device is Figure 2 , Figure 3 or Figure 4 the shape shown.
[0050] In another embodiment, each light source assembly 200 is arranged in a periodic array. With such an arrangement, the arrangement of each light source assembly 200 is relatively regular, so that it is easy to control the brightness of each target area 310.
[0051] As a specific implementation manner, each light source assembly 200 is, for example, Figure 2 , Figure 3 or Figure 4 arranged in a rectangular array as shown.
[0052] In other alternative embodiments, the arrangement of each light source assembly 200 may not be periodic.
[0053] In another embodiment, the light source assembly 200 includes at least two light source modules, including a first light source module and a second light source module. The first light source module and the second light source module face the incident surface of the same lens 210, and the light 400 emitted by the first light source module is visible light, and the light 400 emitted by the second light source module is invisible light.
[0054] The visible light has a good supplementary light illumination effect. When the supplementary light device is applied to a scene that requires a good illumination effect, the first light source module can be independently turned on for supplementary light. The invisible light has good concealment and can be used for concealed supplementary light. When the supplementary light device is applied to concealed scenes such as wildlife observation, the second light source module can be independently turned on for supplementary light. In addition, the visible light may produce glare. By simultaneously turning on the first light source module and the second light source module and using the visible light and the invisible light for common supplementary light, a softer and more uniform supplementary light effect can be achieved without affecting visual perception. In addition, the glare phenomenon can be reduced by turning on the first light source module and / or the second light source module in a specific area and simultaneously turning off the first light source module and the second light source module in the area where the user is located. The specific area depends on the specific situation. It can be seen that the solutions adopted in this embodiment, turning on the first light source module alone, turning on the second light source module alone, and simultaneously turning on the first light source module and the second light source module can respectively meet different usage requirements. In this way, the supplementary light device provided in this embodiment has good applicability and can better meet the usage requirements of users.
[0055] As a specific implementation manner, the visible light is, for example, white light, and correspondingly, the first light source module is, for example, a white light module. The invisible light is, for example, infrared light, and correspondingly, the second light source module is, for example, an infrared module.
[0056] In other alternative embodiments, the number of light source modules included in the same light source assembly 200 may also be one.
[0057] In another embodiment, the supplementary light device further includes a circuit board 100. The light source module includes a lamp bead, and the lamp bead includes a bracket and a light-emitting chip. The light-emitting chip is encapsulated in the bracket through an encapsulation layer and is electrically connected to the circuit board 100 through the bracket, and the light incident surface of the lens 210 faces the light-emitting chip.
[0058] In other alternative embodiments, the light source module may also directly include a light-emitting chip. The light-emitting chip is encapsulated on the circuit board 100 through the lens 210 and is electrically connected to the circuit board 100. The circuit board 100 is, for example, used to control the on / off of the light source module, or the circuit board 100, for example, controls the current input into the light source module, thereby controlling the brightness of the light source module.
[0059] The light-emitting chip of the light source module provided in this embodiment is directly encapsulated on the circuit board 100 and is directly electrically connected to the circuit board 100. In this way, compared with the solution in which the light source module includes lamp beads described above, the supplementary light device provided in this embodiment omits at least the bracket and the encapsulation layer. Therefore, the supplementary light device provided in the embodiments of the present application has a simpler structure and a smaller volume.
[0060] In addition, after the lens 210 is encapsulated outside the light-emitting chip, a closed optical cavity is formed between the lens 210 and the circuit board, and the light-emitting chip is located in this optical cavity. With such a setting, the light-emitting chip is separated from the outside world, so that the light-emitting chip is protected from external damage.
[0061] As a specific implementation manner, the lens 210 is encapsulated outside the light-emitting chip by using, for example, the Chips on Board (COB) technology, and the lens 210 is, for example, a resin lens or a silica gel lens.
[0062] In the embodiments of the present application, a monitoring device is further provided, which includes the supplementary light device described above. As known from the above, the supplementary light device provided in the embodiments of the present application has a good supplementary light effect. The monitoring device includes the supplementary light device described above, so that the monitoring device has a good supplementary light effect, and further, the quality of the image captured by the monitoring device is relatively high. In addition, the supplementary light device described above can perform supplementary light on one target area 310 or multiple target areas 310 separately according to actual needs, so that the energy consumption of the monitoring device is relatively low, and the monitoring device is applicable to more scenarios. In addition, this can also make the control of the monitoring device more flexible.
[0063] It should be noted that the supplementary lighting device described above is not only applicable to monitoring devices, but also applicable to other devices with supplementary lighting requirements.
[0064] In another embodiment, the monitoring device further includes a camera device and a controller. The camera device is used to collect images of each target area 310 and detect the brightness information of each image. The supplementary lighting device includes the circuit board 100 described above. The circuit board is electrically connected to the light source module, and the controller is communicatively connected to both the camera device and the circuit board 100 to adjust the brightness of the corresponding light source module according to the brightness information detected by the camera device. With such a setting, the brightness of the light source module is flexibly adjustable, so that the applicability of the supplementary lighting device is better, and it can be applied to more scenarios. And with such a setting, the supplementary lighting device can better meet the user's usage requirements.
[0065] It can be understood that the greater the current transmitted to the light source module, the greater the brightness of the light source module, and the smaller the current transmitted to the light source module, the smaller the brightness of the light source module.
[0066] During the specific use process, the photosensitive element of the camera device itself can detect the brightness information of the image collected by the camera device. The camera device transmits the brightness information to the controller, and the controller controls the magnitude of the current transmitted to the corresponding light source module according to the brightness information. Specifically, when the brightness of the image corresponding to a certain target area 310 is relatively large, the controller reduces the current transmitted to the light source module corresponding to that target area 310. Conversely, when the brightness of the image corresponding to a certain target area 310 is relatively small, the controller increases the current transmitted to the light source module corresponding to that target area 310.
[0067] Specifically, in practical applications, the problem of unilateral overexposure of the monitoring device screen often occurs due to unilateral reflection. At this time, the light source module corresponding to the overexposed area can be turned off or the input current of the light source module corresponding to the overexposed area can be reduced, and the input current of the light source module in the non-reflective area can be increased to improve the screen effect of the monitoring device.
[0068] In addition, it should also be noted that the light source module is electrically connected to the circuit board 100, and the controller is communicatively connected to the circuit board 100. During the specific use process, the controller sends a control signal to the circuit board 100, and the circuit board 100 controls the magnitude of the current transmitted to the light source module through the received control signal.
[0069] In other alternative embodiments, the monitoring device may not include a controller. In this case, the brightness of the light source module is not adjustable.
[0070] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them fall within the protection scope of the present application.
