In this mode, the LED works with a pulsed high current; 2. Used as a flashlight for night lighting. In this mode, the LED works with a DC constant low current. As an auxiliary artifact for imaging, the flashlight must take into account both the central brightness and the uniformity of the four corners of the emitted light.

The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor 110, and can receive and execute commands sent by the processor 110.

[0077] Based on the above-mentioned smart terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0078] First embodiment

[0079] Figure 5 It is a schematic diagram of the cross-sectional structure of the fill light in the first embodiment of the present application in the high beam mode. Figure 6 Schematic diagram of the cross-sectional structure of the fill light in the soft light mode in the first embodiment of the present application. Figure 5 and Figure 6 As shown, the fill light 10 includes a lampshade 11 and a light source 12. The light-emitting surface of the lampshade 11 has a focusing area 11a and a uniform light area 11b. The focusing area 11a is used to focus light, and the uniform light area 11b is used to scatter light or not change the light path. The light source 12 is located on the light-incident surface of the lampshade 11, and at least part of the light beam emitted by the light source 12 is emitted through the focusing area 11a and / or the uniform light area 11b, that is, the light source 12 is used to selectively provide light to the focusing area 11a of the lampshade 11 alone, to the uniform light area 11b of the lampshade 11 alone, and to the focusing area 11a and the uniform light area 11b at the same time. Optionally, the uniform light area 11b can be frosted so that the uniform light area 11b has a scattering effect on the light; the uniform light area 11b can also use a plane lens without changing the light path, because the light source 12 is usually a point light source and the light emitted is divergent.

[0080] The present application sets a focusing area 11a and a uniform light area 11b on the light-emitting surface of the lampshade 11, and controls the area of ​​the light beam emitted by the light source to irradiate the focusing area 11a and the uniform light area 11b, thereby realizing switching between high beam and soft light. The brightness or uniformity can be freely selected to meet the fill light needs in different scenes, and the cost is relatively low.

[0081] Optionally, the fill light also includes a base plate 13, and the lampshade 11 is connected to the top of the base plate 13, thereby forming a receiving cavity 10a for receiving the light source 12. The light source 12 is located in the receiving cavity 10a between the lampshade 11 and the base plate 13 and connected to the base plate 13.

[0082] Optionally, the light incident surface of the light focusing area 11 a is provided with Fresnel patterns 115 , and the Fresnel patterns 115 are used to focus light.

[0083] Optionally, the light-emitting surface of the focusing area 11a is provided with a focusing convex portion 112, and the focusing convex portion 112 is used to converge light. Optionally, the light-emitting surface of the focusing convex portion 112 is an arc surface, that is, the light-emitting surface of the focusing area 11a is an arc surface, for example, the focusing convex portion 112 is hemispherical, and the focusing convex portion 112 gradually decreases from the light incident surface to the direction close to the light-emitting surface. Of course, the focusing convex portion 112 can also be made of two materials with different refractive indices, so as to have a converging effect on light. In other embodiments, the Fresnel pattern 115 or the focusing convex portion 112 can also be set only in the focusing area 11a, but the focusing effect is poor.

[0084] Optionally, the inner wall of the lampshade 11 is provided with a sawtooth pattern 113, which extends in a vertical direction. The sawtooth pattern 113 is used to scatter light, thereby improving the effect in the soft light mode.

[0085] Optionally, the focusing area 11a is located at the center of the light emitting surface, and the uniform light area 11b is around the periphery of the focusing area 11a, that is, the focusing area 11a is surrounded by the uniform light area 11b. Of course, the positions of the focusing area 11a and the uniform light area 11b on the light emitting surface can also be set according to actual needs, for example, the focusing area 11a and the uniform light area 11b are arranged at intervals.

[0086] In this embodiment, the light source 12 includes a first light source 121 corresponding to the light focusing area 11a and a second light source 122 corresponding to the light uniforming area 11b. The first light source 121 is used to provide light to the light focusing area 11a alone, and the second light source 122 is used to provide light to the light uniforming area 11b alone. Optionally, the number of the first light source 121 is one, and the number of the second light source 122 is two and is arranged at the periphery of the first light source 121. Of course, the number of the first light source 121 and the second light source 122 can also be set according to actual needs.

[0087] Optionally, the light emitting surface (i.e., the light emitting direction) of the first light source 121 faces the light focusing area 11a, and the light emitting surface (i.e., the light emitting direction) of the second light source 122 faces the light uniforming area 11b. Optionally, the light source 12 is also used to selectively provide light to the light uniforming area 11b alone or to the light focusing area 11a alone, that is, the second light source 122 provides light to the light uniforming area 11b alone, and the first light source 121 provides light to the light focusing area 11a alone.

[0088] like Figure 5 As shown, in high beam mode, the first light source 121 is turned on and the second light source 122 is turned off. The first light source 121 provides light to the focusing area 11a alone. The Fresnel patterns 115 and the focusing convex portions 112 of the focusing area 11a converge the light emitted by the first light source 121, thereby reducing the irradiation distance of the light. Figure 6 As shown, in the soft light mode, the second light source 122 is turned on and the first light source 121 is turned off. The second light source 122 provides light to the uniform light area 11b alone, and the uniform light area 11b has a scattering effect on the light or does not change the light path, thereby having a soft light effect. Of course, the first light source 121 and the second light source 122 can also be turned on at the same time to achieve a soft light effect.

[0089] It is found through experiments that when the first light source 121 (240Ma) emits light alone (i.e., the first light source 121 is turned on and the second light source 122 is turned off), the central brightness is twice that of a bare light (without a light cover) (compare the fifth and sixth rows of the table), but the uniformity is relatively low, within 15%, indicating that the focusing effect is good and it can be used as a fill light for a telephoto lens and a high-beam flashlight. When the first light source 121 (40Ma) and the second light source 122 (100ma×2) are turned on at the same time, the uniformity of the four corners can reach 40% (eighth row) through the regulation of the sawtooth pattern 113, and the light at this time is soft light, achieving 1m soft light shooting. Of course, when only the second light source 122 (120Ma) is turned on, its uniformity of the four corners can reach 52% (fourth row), which can also be achieved as soft light.

[0090] Second embodiment

[0091] Figure 7 This is a schematic cross-sectional view of the fill light in the high beam mode in the second embodiment of the present application. Figure 8 This is a schematic cross-sectional view of the fill light in the soft light mode in the second embodiment of the present application. Fig. 9 Schematic diagram of the upward structure of the fill light in the second embodiment of the present application. Figures 7 to 9 As shown, the fill light of this embodiment has substantially the same structure as that of the fill light of the first embodiment, except that the second light source 122 in the fill light 10 of this embodiment is a side-emitting light source, i.e., the light-emitting surface (i.e., the light-emitting direction) of the second light source 122 faces the inner wall of the lampshade 11, thereby reducing space occupancy.

[0092] Specifically, a reflective surface 114 is provided on the outer wall of the lampshade 11, the light-emitting surface of the first light source 121 faces the focusing area 11a, and the light-emitting surface of the second light source 122 faces the reflective surface 114. The reflective surface 114 is used to reflect the light beam emitted by the second light source 122 to the uniform light area 11b.

[0093] Third embodiment

[0094] Fig.10 This is a schematic cross-sectional view of the fill light in the high beam mode in the third embodiment of the present application. Fig.11 FIG. 2 is a schematic cross-sectional view of the fill light in the soft light mode in the third embodiment of the present application. Fig.10 and Fig.11 As shown, the fill light of this embodiment is substantially the same as the fill light of the first embodiment in structure, except that the light source 12 in the fill light 10 of this embodiment only corresponds to the focusing area 11a, that is, there is no need to set the light source 12 in the uniform light area 11b.

[0095] Optionally, the fill light 10 further includes a displacement mechanism connected to the light source 12 to drive the light source 12 to move in a direction perpendicular to the light emitting surface. When the displacement mechanism drives the light source 12 to move to a first position in a direction perpendicular to the light emitting surface, a light spot formed on the light emitting surface by the light beam emitted by the light source 12 overlaps with the light focusing area 11a to achieve a high beam mode; when the displacement mechanism drives the light source 12 to move to a second position in a direction perpendicular to the light emitting surface, a light spot formed on the light emitting surface by the light beam emitted by the light source 12 overlaps with the light focusing area 11a and the uniform light area 11b to achieve a soft light mode.

[0096] Specifically, the displacement mechanism is a lifting mechanism 14, and the light source 12 is connected to one end of the lifting mechanism 14 and can be lifted and lowered in the vertical direction, that is, the light source 12 is connected to the bottom plate 13 through the lifting mechanism 14 and can be lifted and lowered relative to the bottom plate 13. Optionally, the lifting mechanism 14 can adopt a nut screw structure. The lifting mechanism 14 drives the light source 12 to rise to the first position, so that the light of the light source 12 is only directed to the focusing area 11a to achieve the high beam mode; or the lifting mechanism 14 drives the light source 12 to descend to the second position, so that the light of the light source 12 is simultaneously directed to the focusing area 11a and the uniform light area 11b to achieve the soft light mode.

[0097] Fourth embodiment

[0098] Fig.12 This is a schematic cross-sectional view of the fill light in the high beam mode in the fourth embodiment of the present application. Fig.13 FIG. 4 is a schematic cross-sectional view of the fill light in the soft light mode in the fourth embodiment of the present application. Fig.12 and Fig.13 As shown, the fill light of this embodiment is substantially the same in structure as the fill light of the first embodiment, except that the fill light 10 of this embodiment further includes a displacement mechanism connected to the light source 12, which drives the light source 12 to move in a direction parallel to the light emitting surface. When the displacement mechanism drives the light source 12 to move in a direction parallel to the light emitting surface to the third position, the light spot formed by the light beam emitted by the light source 12 on the light emitting surface at least partially overlaps with the focusing area 11a; when the displacement mechanism drives the light source 12 to move in a direction parallel to the light emitting surface to the fourth position, the light spot formed by the light beam emitted by the light source 12 on the light emitting surface at least partially overlaps with the uniform light area 11b. By driving the light source 12 to move horizontally, the area of ​​overlap between the light spot formed by the light beam emitted by the light source 12 on the light emitting surface and the focusing area 11a and the uniform light area 11b is adjusted to achieve the adjustment of the high beam mode and the soft light mode.

[0099] Specifically, the displacement mechanism is a horizontal driving mechanism 15, and the light source 12 is connected to one end of the horizontal driving mechanism 15 and can move in the horizontal direction. The horizontal driving mechanism 15 is used to drive the light source 12 to move between the focusing area 11a and the uniform light area 11b. Optionally, the other end of the horizontal driving mechanism 15 is connected to the base plate 13. Of course, the other end of the horizontal driving mechanism 15 can also be connected to the inner wall of the lampshade 11. The horizontal driving mechanism 15 can adopt a nut screw structure. The light source 12 is driven to move between the focusing area 11a and the uniform light area 11b by the horizontal driving mechanism 15. When it moves to the third position, the light source 12 corresponds to the focusing area 11a to realize the high beam mode; or when it moves to the fourth position, the light source 12 corresponds to the uniform light area 11b to realize the soft light mode.
