[0002] An intelligent terminal is provided with a flash lamp and a lamp cover that cooperates with the flash lamp. The light emitted by the LED flash lamp at the bottom passes through the lamp cover at the top and is emitted outward. Since the material of the lamp cover is PMMA or PET plastic, the size and shape of the lamp cover are fixed after processing.

[0003] In the process of conceiving and implementing this application, the inventors found at least the following problems: The existing lamp cover cannot actively regulate the light effect and light output energy of the flash lamp, so the existing lamp cover cannot cooperate to adapt to the shooting of different cameras in different scenarios.

[0004] The foregoing description is for general background information and does not necessarily constitute prior art. Summary of the Utility Model

[0005] The purpose of this application is to provide a lamp cover device that can actively regulate the light effect and light output energy.

[0006] To solve the above technical problems, this application provides a lamp cover device, including a transparent support plate, a transparent elastic layer, and a driver arranged in the light output direction of a supplementary light source. The transparent elastic layer is arranged on the transparent support plate, and the driver is arranged on the periphery of the transparent elastic layer. The driver is used to squeeze the transparent elastic layer towards the center according to the received control signal, so that the light output surface of the transparent elastic layer bulges to form a light condensing part for light condensation.

[0007] Optionally, the lamp cover device further includes a cover body former, and the cover body former includes a baffle covering the transparent elastic layer. A conical groove for the light condensing part to protrude is provided on the baffle; the top of the outer surface of the conical groove is an arc surface for converging light, and the cross-sectional diameter of the conical groove gradually decreases in the light output direction of the supplementary light source.

[0008] Optionally, the ratio of the height (h) of the conical groove in the optical axis direction to the radius (r) of the light input surface is 1-3.

[0009] Optionally, the cover body former and the transparent elastic layer are made of the same material.

[0010] Optionally, the refractive index of the material of the cover body former is greater than the refractive index of the material of the transparent elastic layer.

[0011] Optionally, the refractive index of the material of the cover body former is greater than the refractive index of the material of the transparent elastic layer, and the depth of the conical groove is less than the height of the cover body former.

[0012] Optionally, a second light-shielding layer is provided on the lower surface of the transparent support plate facing away from the baffle. A second light-transmitting area is formed in the center surrounded by the second light-shielding layer. The orthographic projection area of the second light-transmitting area on the transparent support plate coincides at least partially with that of the first light-transmitting area.

[0013] Optionally, Fresnel stripes are provided on the second light-transmitting area.

[0014] Optionally, the lamp cover device further includes a cover body for accommodating a supplementary light source, and the transparent support plate, the transparent elastic layer and the driver are provided on the cover body.

It can control the bulge height of the light-condensing part according to different scene requirements. The greater the bulge height of the light-condensing part, the better the light-condensing effect, the greater the brightness of the light-emitting center, and the greater the light irradiation distance, which is suitable for matching with a telephoto camera for long-distance shooting; the smaller the bulge height of the light-condensing part, the smaller the brightness of the light-emitting center, but the greater the uniformity of the four corners and the greater the brightness of the four corners, which is suitable for matching with the main camera and wide-angle camera for close-range shooting. That is, the lamp cover device of this application can actively regulate the light effect and light-emitting energy, and can meet the supplementary light requirements of different scenes without increasing the power consumption of the light source.

[0064] The First Embodiment

[0065] Figure 3 is a schematic cross-sectional structure diagram of the lampshade device according to the first embodiment of this application, Figure 4 and Figure 5 is a schematic cross-sectional structure diagram of different heights of the convex part of the light condensing part according to this application, as Figure 3 , Figure 4 and Figure 5As shown in the figure, the lamp cover device includes a transparent support plate 11, a transparent elastic layer 12, and a driver 13 disposed in the light-emitting direction of the supplementary light source 15. The transparent elastic layer 12 is disposed on the transparent support plate 11, and the driver 13 is disposed on the periphery of the transparent elastic layer 12. The driver 13 is used to squeeze the transparent elastic layer 12 toward the center according to the received control signal, so that the light-emitting surface of the transparent elastic layer 12 bulges to form a condensing portion 121 for condensing light. In this embodiment, the condensing portion 121 is located in the middle area of the transparent elastic layer 12; the transparent elastic layer 12 has elasticity and plays a role in deforming adjustment and light effect regulation; it can deform under the driving and squeezing of the driver 13. For example, when the driver 13 squeezes the transparent elastic layer 12 from the periphery of the transparent elastic layer 12 toward its center, the middle part of the transparent elastic layer 12 can bulge upward to form a condensing portion 121 equivalent to a condensing lens; when the driver 13 retracts, before the transparent elastic layer 12 restores its deformation, that is, the convex height of the condensing portion 121 gradually returns to the horizontal state.

[0066] The lamp cover device of the present application can drive and squeeze the transparent elastic layer 12 through the driver 13 to make its light-emitting surface bulge to form a condensing portion 121 for condensing light. It can control the convex height of the condensing portion 121 according to the needs of different scenarios. The greater the convex height of the condensing portion 121, the better the condensing effect, the greater the brightness of the light-emitting center, and the greater the light irradiation distance. It is suitable for matching with a telephoto camera for long-distance shooting; the smaller the convex height of the condensing portion, the smaller the brightness of the light-emitting center, but the greater the uniformity of the four corners and the greater the brightness of the four corners. It is suitable for matching with the main camera and wide-angle camera for close-range shooting. That is, the lamp cover device of the present application can actively regulate the light effect and the light-emitting energy, and can meet the supplementary light requirements of different scenarios without increasing the power consumption of the light source 15.

[0067] Optionally, the lamp cover device further includes a cover body former, and the cover body former includes a baffle 14 covering the transparent elastic layer 12. The baffle 14 is provided with a light passing hole 301 for the condensing portion 121 to protrude. In this embodiment, the light passing hole 301 is directly opposite to the middle area of the transparent elastic layer 12; the baffle 14 is used to prevent the area of the transparent elastic layer 12 other than the condensing portion 121 from deforming, so that the acting force of the driver 13 is concentrated in the middle part of the transparent elastic layer 12, and then the required height for the condensing portion 121 to bulge can be achieved.

[0068] Optionally, the light passing hole 301 is a circular hole.

[0069] Optionally, the surface of the condensing portion 121 away from the transparent support plate 11 is a circular arc surface for converging light. The larger the curvature radius of the circular arc surface, the greater the brightness of the light effect; after the light passes through multiple reflections and refractions in the condensing portion 121, the energy is concentrated and converged, resulting in a significant increase in brightness.

[0070] Optionally, the lamp shade device further includes a fastener (not shown in the figure), and the baffle 14 is fixedly connected to the transparent support plate 11 through at least one fastener, that is, the transparent elastic layer 12 is limited between the transparent support plate 11 and the baffle 14.

[0071] In other embodiments, the baffle 14 can be fixed to other structures, such as the housing of a smart terminal.

A first light-transmitting area 112 is formed in the center of the first light-shielding layer 1131. The transparent elastic layer 12 covers the first light-shielding layer 1131, and the orthographic projection areas of the first light-transmitting area 112 and the light-transmitting hole 301 on the transparent support plate 11 at least partially overlap. In this embodiment, the first light-shielding layer 1131 is a black coating for preventing light leakage; the first light-shielding layer 1131 is, for example, annular, and the first light-transmitting area 112 is circular.

[0074] Optionally, a second light-shielding layer 1132 is provided on the lower surface of the transparent support plate 11 facing away from the baffle 14. A second light-transmitting area 114 is formed in the center surrounded by the second light-shielding layer 1132. The orthographic projection areas of the second light-transmitting area 114 and the first light-transmitting area 112 on the transparent support plate 11 at least partially overlap.
