The light-emitting device 500 is integrated in the camera module, so the light-emitting device 500 does not additionally occupy the display of the electronic device. Area, so that the screen-to-body ratio of electronic devices increases accordingly. In addition, when using this solution, the function of the camera module is not limited to shooting, it also has a light-emitting function, so the function of the camera module is more diversified, so as to better meet the needs of users.
考虑到上述发光器件500发出的光线可能会对摄像头模组的拍摄功能造成干扰，因此为了尽量降低发光器件500对摄像头模组的正常拍摄造成不良影响，一种可选的实施例中，可以使摄像头模组具有第一状态和第二状态。 其中：在第一状态下，图像传感器400处于感光状态，发光器件500处于非工作状态，此时，发光器件500不发光，图像传感器400可以正常感应自外部环境进入摄像头模组内的光线；在第二状态下，图像传感器400处于非感光状态，发光器件500处于工作状态，此时，发光器件500可以发光，而图像传感器400则不工作。需要说明的是，图像传感器400处于非感光状态时，图像传感器400不再实现光电信号的转换，此时，图像传感器400与电路板300之间的电连接回路可以被切断，从而使得图像传感器400无法感光；或者，可以额外增加遮光结构，该状态下可以使遮光结构运动至图像传感器400的上方，从而阻挡光线到达图像传感器400，使得图像传感器400无法感光。当然，还可以采用其他方式使得图像传感器400处于非感光状态，本文对此不做限制。Considering that the light emitted by the light-emitting device 500 may interfere with the shooting function of the camera module, in order to minimize the adverse effect of the light-emitting device 500 on the normal shooting of the camera module, in an optional embodiment, The camera module has a first state and a second state. Wherein: in the first state, the image sensor 400 is in a photosensitive state, and the light-emitting device 500 is in a non-working state. At this time, the light-emitting device 500 does not emit light, and the image sensor 400 can normally sense the light entering the camera module from the external environment; In the second state, the image sensor 400 is in a non-photosensitive state and the light-emitting device 500 is in an operating state. At this time, the light-emitting device 500 can emit light, but the image sensor 400 does not work. It should be noted that when the image sensor 400 is in a non-photosensitive state, the image sensor 400 no longer implements photoelectric signal conversion. At this time, the electrical connection loop between the image sensor 400 and the circuit board 300 can be cut off, so that the image sensor 400 It cannot be light-sensitive; or, an additional light-shielding structure can be added. In this state, the light-shielding structure can be moved above the image sensor 400, thereby blocking light from reaching the image sensor 400, making the image sensor 400 unable to light-sensitize. Of course, other methods can also be used to make the image sensor 400 in a non-photosensitive state, which is not limited herein.
采用上述技术方案后，图像传感器400和发光器件500可以独立工作，从而防止图像传感器400和发光器件500同时工作时导致两者之间容易出现干扰的问题。因此，该方案可以提升图像传感器400的工作质量，同时发光器件500发光时，图像传感器400可以不工作，从而可以降低该摄像头模组的功耗，同时可以延长图像传感器400的使用寿命。After adopting the above technical solution, the image sensor 400 and the light emitting device 500 can work independently, thereby preventing the problem of interference between the image sensor 400 and the light emitting device 500 when the image sensor 400 and the light emitting device 500 work at the same time. Therefore, this solution can improve the working quality of the image sensor 400, and at the same time, the image sensor 400 may not work when the light emitting device 500 emits light, thereby reducing the power consumption of the camera module and prolonging the service life of the image sensor 400.
一种可选的实施例中，电路板300具体可以包括第一子电路板310和第二子电路板320，第一子电路板310分别与支架100和第二子电路板320相连，第二子电路板320相对于支架100外伸，以便于该第二子电路板320与其他器件(例如电子设备的主板)相连。此时，图像传感器400和发光器件500可以通过表面贴装工艺(Surface Mounted Technology，SMT)等方式设置于第一子电路板310上，图像传感器400和发光器件500之间可以具有一定的间隔，从而防止两者直接接触而对两者的结构带来损伤。另外，图像传感器400和发光器件500所在的平面可以平行，或者重合。具体地，发光器件500可以设置于第一子电路板310的任意位置处，但是考虑到图像传感器400的位置和尺寸会直接影响摄像头模组的拍摄效果，因此可以将发光器件500设置于第一子电路板310的边缘处。即，发光器件500尽量远离第一子电路板310的中心区域，从而使得第一子电路板310具有更大的空间来设置图像传感器400，以便于提升摄像头模组的拍摄效果。In an alternative embodiment, the circuit board 300 may specifically include a first sub-circuit board 310 and a second sub-circuit board 320. The first sub-circuit board 310 is connected to the support 100 and the second sub-circuit board 320 respectively, and the second The sub-circuit board 320 extends relative to the bracket 100 to facilitate the connection of the second sub-circuit board 320 with other devices (such as the main board of an electronic device). At this time, the image sensor 400 and the light-emitting device 500 may be arranged on the first sub-circuit board 310 by a surface mount technology (SMT) or the like, and there may be a certain interval between the image sensor 400 and the light-emitting device 500, This prevents direct contact between the two and damage to the structure of the two. In addition, the planes on which the image sensor 400 and the light emitting device 500 are located may be parallel or overlapped. Specifically, the light emitting device 500 can be arranged at any position of the first sub-circuit board 310, but considering that the position and size of the image sensor 400 will directly affect the shooting effect of the camera module, the light emitting device 500 can be arranged on the first sub-circuit board 310. The edge of the sub-circuit board 310. That is, the light-emitting device 500 is as far away as possible from the central area of the first sub-circuit board 310, so that the first sub-circuit board 310 has a larger space for arranging the image sensor 400, so as to improve the shooting effect of the camera module.
如前文所述，支架100可以设有通光孔110，滤光片700的入光面与该通光孔110相对。一种可选的实施例中，如图1所示，摄像头模组还包括导光件600，该导光件600设置于支架100上，导光件600的入光面与发光器件500相对，导光件600位于前文所述的导光通道内，且导光件600的出光面至少部分朝向通光孔110。这里的导光件600可以实现光线的导向，因此发光器件500发出的光可以首先进入导光件600内，这些光线的传播方向在导光件600内发生变化，从而可以通过导光件600进入通光孔110，进一步通过通光孔110穿过滤光片700，最终通过镜片组200射出。可见，设置该导光件600时，发光器件500发出的光线可以通过导光件600可靠地射出，因此发光器件500的设置位置更加灵活。As mentioned above, the support 100 may be provided with a light-passing hole 110, and the light-incident surface of the filter 700 is opposite to the light-passing hole 110. In an optional embodiment, as shown in FIG. 1, the camera module further includes a light guide 600, the light guide 600 is disposed on the bracket 100, and the light incident surface of the light guide 600 is opposite to the light emitting device 500, The light guide 600 is located in the light guide channel described above, and the light exit surface of the light guide 600 faces at least part of the light through hole 110. The light guide 600 here can guide light, so the light emitted by the light emitting device 500 can first enter the light guide 600, and the propagation direction of these lights changes in the light guide 600, so that it can enter through the light guide 600 The light-passing hole 110 further passes through the filter 700 through the light-passing hole 110, and finally exits through the lens assembly 200. It can be seen that when the light guide member 600 is installed, the light emitted by the light emitting device 500 can be reliably emitted through the light guide member 600, so the installation position of the light emitting device 500 is more flexible.
可选地，导光件600的一部分设于支架100，导光件600的另一部分与通光孔110相对，或者，导光件600的另一部分伸入通光孔110。此时，导光件600的一部分位于支架100的下方，两者的连接面积更大，从而使得导光件600的结构强度更高，其相对于发光器件500的位置精度更高，从而更准确地实现光线导向，使得发光器件500所发出的光线可以更多地射出，达到提升发光器件500的发光效果的目的。而导光件600与通光孔110相对的部分或者导光件600伸入通光孔110的部分则可以实现光线的射出，从而可靠地保证发光器件500发出的光线可以通过导光件600射出。另外，如此设置后，导光件600可以更远离通光孔110的中心线，当外部环境中的光线进入摄像头模组时，导光件600更不容易阻挡这些光线的传播，以此提升摄像头模组的拍摄效果。Optionally, a part of the light guide 600 is disposed on the support 100, and another part of the light guide 600 is opposite to the light through hole 110, or another part of the light guide 600 extends into the light through hole 110. At this time, a part of the light guide 600 is located under the bracket 100, and the connection area between the two is larger, so that the structural strength of the light guide 600 is higher, and the position accuracy of the light guide 600 relative to the light emitting device 500 is higher, and thus more accurate The light guiding is realized so that the light emitted by the light-emitting device 500 can be emitted more, so as to achieve the purpose of improving the light-emitting effect of the light-emitting device 500. The part of the light guide 600 opposite to the light-passing hole 110 or the part of the light guide 600 that extends into the light-passing hole 110 can realize the emission of light, so as to reliably ensure that the light emitted by the light-emitting device 500 can be emitted through the light guide 600 . In addition, after being arranged in this way, the light guide 600 can be farther away from the center line of the light hole 110. When the light in the external environment enters the camera module, the light guide 600 is less likely to block the propagation of the light, thereby enhancing the camera. The shooting effect of the module.
上述导光件600的具体结构可以灵活选择，为了减小导光件600所占用的空间，可以将该导光件600设置为导光膜，以使摄像头模组有更多的空间设置图像传感器400、发光器件500等零部件。The specific structure of the light guide 600 can be flexibly selected. In order to reduce the space occupied by the light guide 600, the light guide 600 can be set as a light guide film, so that the camera module has more space for the image sensor. 400, light-emitting device 500 and other parts.
如前文所述，支架100可以设有通光孔110，滤光片700可以覆盖该通光孔110。基于此，另一种可选的实施例中，如图2所示，发光器件500的出光面至少部分与通光孔110相对。也就是说，发光器件500发出的至少一部分光线可以直接进入通光孔110，从而通过该通光孔110射入镜片组200。此时，即使不设置导光结构(例如上文实施例所述的导光件600)，发光器件 500发出的光线也可以顺利射出摄像头模组，该结构一方面可以减少摄像头模组所包含的零部件的数量，从而简化摄像头模组的结构，同时便于其他零部件的布局；另一方面，外部环境中的光线射入摄像头模组时，不会受到导光结构的阻挡，因此摄像头模组的拍摄效果更优。As mentioned above, the support 100 may be provided with a light-passing hole 110, and the filter 700 can cover the light-passing hole 110. Based on this, in another alternative embodiment, as shown in FIG. 2, the light emitting surface of the light emitting device 500 is at least partially opposite to the light through hole 110. In other words, at least part of the light emitted by the light-emitting device 500 can directly enter the light-passing hole 110, so as to enter the lens group 200 through the light-passing hole 110. At this time, even if the light guide structure (such as the light guide 600 described in the above embodiment) is not provided, the light emitted by the light emitting device 500 can be smoothly emitted out of the camera module. This structure can reduce the amount of light contained in the camera module on the one hand. The number of parts, thereby simplifying the structure of the camera module, and facilitating the layout of other parts; on the other hand, when the light in the external environment enters the camera module, it will not be blocked by the light guide structure, so the camera module The shooting effect is better.
如图3所示，可选地，发光器件500可以倾斜设置于电路板300上，发光器件500的出光面朝向镜片组200的入光面。通过倾斜设置发光器件500的方式可以适当调整发光器件500的出光方向，使得发光器件500发出的光线更不容易被支架100遮挡，从而更容易进入镜片组200，因此此种结构一方面不需要设置上文所述的导向结构，另一方面可以适当增大发光器件500与通光孔110的中心线之间的距离，使得图像传感器400的尺寸可以进一步增大，从而优化摄像头模组的拍摄效果。As shown in FIG. 3, optionally, the light-emitting device 500 can be arranged on the circuit board 300 obliquely, and the light-emitting surface of the light-emitting device 500 faces the light-incident surface of the lens assembly 200. By obliquely setting the light-emitting device 500, the light-emitting direction of the light-emitting device 500 can be adjusted appropriately, so that the light emitted by the light-emitting device 500 is less likely to be blocked by the holder 100, so that it is easier to enter the lens group 200. Therefore, this structure does not need to be installed on the one hand. The guide structure described above, on the other hand, can appropriately increase the distance between the light emitting device 500 and the center line of the through hole 110, so that the size of the image sensor 400 can be further increased, thereby optimizing the shooting effect of the camera module. .
上述发光器件500的倾斜角度可以灵活选择，为了使得发光器件500发出的光线更容易进入镜片组200，可以使发光器件500分别与电路板300和支架100抵触。也就是说，发光器件500可以占用电路板300和支架100之间的整个空间，此时发光器件500的倾斜角度基本处于最大状态，发光器件500发出的更多光线可以进入镜片组200，发光器件500的发光效果可以得到进一步的改善。可见，此结构可以充分利用电路板300和支架100之间的空间，既可以保证发光器件500发出的光线更可靠地进入镜片组200，还可以进一步增大发光器件500与通光孔110的中心线之间的距离，从而达到提升摄像头模组的拍摄效果这一目的。The tilt angle of the light emitting device 500 can be flexibly selected. In order to make the light emitted by the light emitting device 500 easier to enter the lens group 200, the light emitting device 500 can be made to interfere with the circuit board 300 and the bracket 100 respectively. In other words, the light-emitting device 500 can occupy the entire space between the circuit board 300 and the bracket 100. At this time, the tilt angle of the light-emitting device 500 is basically at the maximum state, and more light emitted by the light-emitting device 500 can enter the lens group 200. The luminous effect of 500 can be further improved. It can be seen that this structure can make full use of the space between the circuit board 300 and the bracket 100, which can ensure that the light emitted by the light-emitting device 500 enters the lens group 200 more reliably, and can further increase the center of the light-emitting device 500 and the light-passing hole 110. The distance between the lines, so as to achieve the purpose of improving the shooting effect of the camera module.
