Referring to fig. 2, fig. 3 and fig. 4, fig. 2 is a schematic structural diagram of an embodiment of a camera head assembly 80 of the present application, fig. 3 is a schematic structural diagram of another angle of the embodiment of the camera head assembly 80 of the present application, and fig. 4 is a schematic structural diagram of an explosion of the embodiment of the camera head assembly 80 shown in fig. 2. The flash assembly 830 includes a lamp housing 10, a light guide film 20 and at least one flash lamp 30, wherein the lamp housing 10 is provided with a first through hole 110, it should be noted that the flash assembly 830 is disposed adjacent to the camera 820, the camera 820 needs a lighting opening, that is, corresponds to the first through hole 110, and light is collected by the camera 820 through the first through hole 110 to obtain external image information. The lamp cover 10 includes a light-transmitting layer 120 sequentially surrounding along the periphery of the first through hole 110. The light guide film 20 includes a second through hole 210 corresponding to the first through hole 110, and the shape of the light guide film 20 is adapted to the transparent layer 120. The flash lamp 30 is disposed on a side of the light guiding film 20 away from the lampshade 10, and light emitted by the flash lamp 30 can be emitted uniformly and outwardly in the lampshade 10 after passing through the light guiding film 20. The plurality of flash lamps 30 are used for emitting light to the outside, the light path is sequentially through the light guide film 20 and the lamp housing 10, and the light guide film 20 is used for uniformly diffusing the light of the flash lamps 30 and emitting the light from the lamp housing 10 to the outside.

Fig. 4 shows only some embodiments of the present application, and not all embodiments of the present application.

Fig. 5, 6 and 7, in which fig. 5 is a schematic structural view of an embodiment of the light guide film 20 shown in fig. 4, fig. 6 is a schematic structural view of another embodiment of the light guide film 20 shown in fig. 4, and fig. 7 is a schematic structural view of a third embodiment of the light guide film 20 shown in fig. 4. The light guide film 20 is provided with the light guide structures 220, and the density of the light guide structures 220 gradually increases from a region close to the flash lamp 30 to a region far from the flash lamp 30. It should be noted that the portion of the light guide structure 220 close to the flash lamp 30 obtains the most light, and the portion far from the flash lamp 30 compensates the brightness loss of the light at the far position because the density of the light guide structure 220 is greater. For example, when the number of the flash lamps 30 is 2 and the second through holes 210 are symmetrically arranged in a diameter direction, the density of the light guide structures 220 is relatively small at a position close to the flash lamps 30, and the light guide structures 220 are denser towards two end positions of the diameter concentric with and perpendicular to the diameter, and the distance between the position and the two flash lamps 30 is further, but the increase of the density can compensate the loss of brightness. With this arrangement, even when two flashlamps 30 are provided, the light passing through the light guide film 20 can be made uniform. Referring specifically to fig. 4, at a position close to the flash lamp 30 at the light guide structures 220, the distance between adjacent light guide structures 220 gradually decreases with a direction away from the flash lamp 30, such as a distance Q and a distance W, where the distance Q is greater than the distance W, and the distance Q is closer to the flash lamp 30, and the position of W is farther from the flash lamp 30. So set up, alright in order to make light guide structure 220 utilize the density degree of unit density to compensate the loss of light, and then make the light after passing through light guiding film 20 can outwards spill evenly.

At least two sets of light guide structures 220 with different densities are arranged on the light guide film 20, and the at least two sets of light guide structures 220 are circumferentially arranged along the second through hole 210. In an embodiment of the present application, the flash lamp 30 is disposed at a position of the light guide structure 220 with a lower density, and the light guide structure 220 with a higher density is correspondingly disposed at a position far away from the flash lamp 30, so as to compensate for the loss of brightness.

Referring to fig. 6 and 7, the light guide structure 220 is a light guide stripe or a light guide dot, and the light guide stripe or the light guide dot is uniformly arranged along the circumferential direction of the second through hole 210 at intervals, and is used for uniformly diffusing the light emitted by the flash lamp 30 after passing through the light guide structure 220. It is understood that the light guide stripes and the light guide dots are only one of the embodiments of the present application, and that simple variations of the shapes of the light guide stripes and the light guide dots are also within the scope of the present application. The light guide stripes and the light guide dots may gradually increase in density from a region close to the flash lamp 30 to a region far from the flash lamp 30. The light guide stripes and the light guide dots may also be disposed in a plurality of regions, for example, a portion close to the flash lamp 30 is a first region, and a portion far from the flash lamp 30 is a second region.

Referring to fig. 8 and 9, fig. 8 is a schematic structural view of a fourth embodiment of the light guide film 20 shown in fig. 4, and fig. 9 is a schematic structural view of a fifth embodiment of the light guide film 20 shown in fig. 4. In an embodiment of the present application, the number of the flash lamps 30 is 2. In other embodiments, the number of flashlights 30 is not limited and is provided as an example only.

Further, the first light guide structure 2210 includes a first light guide region 2211 and a second light guide region 2213, and the second light guide structure 2230 includes a third light guide region 2231 and a fourth light guide region 2233; the density of the first light guide region 2211 is consistent with that of the second light guide region 2213, the density of the third light guide region 2231 is consistent with that of the fourth light guide region 2233, and the first light guide region 2211, the third light guide region 2231, the second light guide region 2213 and the fourth light guide region 2233 are uniformly arranged at intervals along the circumferential direction of the second through hole 210. The flash lamp 30 is located in the first light guide region 2211 and the second light guide region 2213, and the first light guide region 2211 and the second light guide region 2213 are disposed at an interval and are respectively adjacent to the third light guide region 2231 and the fourth light guide region 2233. That is, the light emitted from the flash lamp 30 obtained by the first light guide region 2211 and the second light guide region 2213 is larger than the light emitted from the flash lamp 30 obtained by the third light guide region 2231 and the fourth light guide region 2233. However, the density of the third light guide region 2231 and the fourth light guide region 2233 is greater than the density of the first light guide region 2211 and the second light guide region 2213, so that the loss of brightness of the flash 30 at the third light guide region 2231 and the fourth light guide region 2233 can be compensated. With this arrangement, the light emitted from the flash 30 passes through the first light guide region 2211, the second light guide region 2213, the third light guide region 2231 and the fourth light guide region 2233 and then becomes uniform, so that the light emitted from the lamp housing 10 is also uniform. The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

The light guide structure 220 includes a first light guide structure 2210, a second light guide structure 2230, and a third light guide structure 2250, and the densities of the first light guide structure 2210, the second light guide structure 2230, and the third light guide structure 2250 are sequentially increased. Further, the position of the flash 30 corresponds to the position of the first light guide structure 2210, and the distances of the second light guide structure 2230 and the third light guide structure 2250 from the flash 30 gradually increase. Taking 2 flash lamps 30 as an example, the flash lamps 30 are disposed at the first light guide structure 2210, and the distances from the second light guide structure 2230 and the third light guide structure 2250 to the first light guide structure 2210 are gradually increased and the densities of the second light guide structure 2230 and the third light guide structure 2250 to the first light guide structure 2210 are also gradually increased, so that the increase in the densities of the second light guide structure 2230 and the third light guide structure 2250, which are far away, compensates for the loss of brightness, and the light rays passing through the first light guide structure 2210, the second light guide structure 2230, and the third light guide structure 2250 are uniformly diffused.

The first light guide structure 2210 includes a first light guide region 2211 and a second light guide region 2213 symmetrically arranged along a diameter of the second through hole 210, and the flash 30 is respectively arranged on the first light guide region 2211 and the second light guide region 2213; the second light guide structure 2230 includes a third light guide region 2231 and a fourth light guide region 2233 adjacent to the first light guide region 2211, and a fifth light guide region 2235 and a sixth light guide region 2237 adjacent to the second light guide region 2213, the third light guide region 2231 and the sixth light guide region 2237 are disposed on the same side, and the fourth light guide region 2233 and the fifth light guide region 2235 are disposed on the same side; the third light guide structure 2250 includes a seventh light guide region 2251 disposed adjacent to the fourth light guide region 2233 and the fifth light guide region 2235, and an eighth light guide region 2253 disposed adjacent to the third light guide region 2231 and the sixth light guide region 2237.

Taking 2 flash lamps 30 as an example, the flash lamps 30 may be disposed in the first light guide region 2211 and the second light guide region 2213, and it is understood that a plurality of flash lamps 30 may be disposed in the first light guide region 2211, or a plurality of flash lamps 30 may be disposed in the second light guide region 2213, as long as the number of flash lamps 30 at the second light guide region 2213 is less than that of the first light guide region 2211. Thus, the fourth light guide region 2233 and the fifth light guide region 2235 are closer to the flash 30 than the seventh light guide region 2251, and the density of the seventh light guide region 2251 is greater than the fourth light guide region 2233 and the fifth light guide region 2235. Similarly, the third light guide region 2231 and the sixth light guide region 2237 are closer to the flash 30 than the eighth light guide region 2253, and the density of the eighth light guide region 2253 is greater than the third light guide region 2231 and the sixth light guide region 2237, thereby compensating for the loss of brightness at the eighth light guide region 2253. It is understood that the number of the flash lamps 30 may be multiple, for example, two flash lamps 30 are respectively disposed on the first light guide region 2211 and the second light guide region 2213, one flash lamp 30 is respectively disposed on the third light guide region 2231, the fourth light guide region 2233, the fifth light guide region 2235 and the sixth light guide region 2237, and the like, as long as the brightness of the light obtained by the first light guide structure 2210, the second light guide structure 2230 to the third light guide structure 2250 is different, and the density of the second light guide structure 2230 and the third light guide structure 2250 is increased compared to the density of the first light guide structure 2210 to compensate for the lost brightness while the light obtained by the second light guide structure 2210 is weakened by the second light guide structure 2230 and the third light guide structure 2250.
