[0052] This application provides a soft flash lamp structure. The soft flash lamp structure includes a soft light, a soft lens, and a light shield. The soft lens includes a curved reflective lens section, a flat lens section, and a condenser lens section arranged sequentially. The curved reflective lens section has an incident curved surface and a reflecting curved surface on opposite sides, both curved away from the flat lens section. The flat lens section has a reflecting plane on opposite sides, and the condenser lens section has a condensing reflecting surface and a light-emitting surface on opposite sides. The incident curved surface, one reflecting plane, and the condensing reflecting surface are sequentially connected, as are the reflecting surface, the other reflecting plane, and the light-emitting surface. The soft light, the curved reflective lens section, the flat lens section, and the condenser lens section are housed together within the light shield, with the light-emitting surface exposed outside the light shield. The light emitted by the soft light is at least partially incident on the incident curved surface and sequentially reflected by the reflecting surface, the two reflecting planes, and the condensing reflecting surface, before exiting through the light-emitting surface.

[0053] The aforementioned soft-light flash lamp structure connects the incident light surface, one of its reflecting planes, and the focusing reflecting surface in sequence, and the reflecting surface, the other reflecting plane, and the light-emitting surface in sequence. This results in one side of the soft-light lens being composed of the incident light surface, one of its reflecting planes, and the focusing reflecting surface connected in sequence, and the other side being composed of the reflecting surface, the other reflecting plane, and the light-emitting surface connected in sequence. Both the incident light surface and the reflecting surface are curved away from the planar lens section, so that at least part of the light emitted by the soft light lamp enters the incident light surface and passes through the curved reflecting lens section. This causes more of the light emitted by the soft light lamp to enter the planar lens section at an inclined angle and at least part of it to be reflected between the two reflecting planes of the planar lens section and propagate away from the curved reflecting lens section to the focusing lens section. The focusing lens section focuses and reflects the incoming light through the focusing reflecting surface and emits it from the light-emitting surface, thus achieving the formation of a gradually softened light spot with better light uniformity.

[0054] To better understand the soft flash structure of this application, the following further explanation is provided:

[0055] Please refer to the following: Figures 1 to 4One embodiment of the soft flash lamp structure 10 includes a soft flash lamp 100, a soft flash lens 200, and a light shield 300. The soft flash lens 200 includes a curved reflective lens section 210, a flat lens section 220, and a condenser lens section 230 arranged in sequence. The curved reflective lens section 210 has an incident light curved surface 201 and a reflective curved surface 202 on opposite sides, respectively. Both the incident light curved surface 201 and the reflective curved surface 202 are curved away from the flat lens section 220. The flat lens section 220 has a reflective plane 203 on opposite sides, and the condenser lens section 230 has a condenser reflective surface 204 and a light-emitting surface 205 on opposite sides. The incident light curved surface 201, one of the reflective planes 203, and the condenser reflective surface 204 are connected in sequence, and the reflective curved surface 202, the other reflective plane 203, and the light-emitting surface 205 are connected in sequence. The soft light 100, the curved reflective lens 210, the flat lens 220, and the focusing lens 230 are housed together within the light shield 300, with the light-emitting surface 205 exposed outside the light shield 300. The light emitted by the soft light 100 is at least partially incident on the incident curved surface 201 and reflected sequentially by the reflective curved surface 202, the two reflective planes 203, and the focusing reflective surface 204, and then emitted through the light-emitting surface 205.

[0056] The aforementioned soft-light flash structure 10 comprises an incident surface 201, a reflecting plane 203, and a focusing reflecting surface 204 connected in sequence; and a reflecting surface 202, another reflecting plane 203, and a light-emitting surface 205 connected in sequence. This results in one side of the soft-light lens 200 being composed of the incident surface 201, a reflecting plane 203, and a focusing reflecting surface 204 connected in sequence, and the other side of the soft-light lens 200 being composed of the reflecting surface 202, another reflecting plane 203, and a light-emitting surface 205 connected in sequence. The incident surface 201 and the reflecting surface 204... Both 202 are curved in a direction away from the plane lens section 220, so that the light emitted by the soft light lamp 100 enters at least part of the incident light curved surface 201 and passes through the curved surface reflecting lens section 210. This causes more of the light emitted by the soft light lamp 100 to enter the plane lens section 220 at an inclined angle and be reflected at least partially between the two reflecting surfaces 203 of the plane lens section 220, propagating in a direction away from the curved surface reflecting lens section 210 to the incident light focusing lens section 230. The focusing lens section 230 focuses and reflects the incident light through the focusing reflective surface 204 and emits it from the light emitting surface 205. Please refer to the following: Figures 8 to 9 The soft flash structure 10 achieves the formation of a light spot with a gradual and softer gradient and better light uniformity.

[0057] Please refer to the following: Figures 1 to 4In one embodiment, the incident light surface 201 is a conical incident light surface. Further, the reflecting surface 202 is a conical reflecting surface. Further, each reflecting plane 203 is an annular reflecting plane. Further, the focusing reflecting surface 204 is an annular focusing reflecting surface. Further, the emitting light surface 205 is an annular emitting light surface. Further, the focusing reflecting surface 204 is arranged around the corresponding reflecting plane 203, and one of its reflecting planes 203 is arranged around the incident light surface 201. Further, the emitting light surface 205 is arranged around the corresponding reflecting plane 203, and the other reflecting plane 203 is arranged around the reflecting surface 202. Further, the geometric center point of the projection of the light-emitting area of ​​the soft light lamp 100 onto the incident light surface 201 is located at the conical apex of the incident light surface 201, achieving the formation of a gradually softened light spot with better light uniformity in the area surrounded by the emitting light surface 205.

[0058] Please refer to the following: Figures 2 to 5 In one embodiment, the number of soft lights 100 is multiple. Further, the number of curved reflective lens sections 210 is multiple, with each soft light 100 corresponding to one of the multiple curved reflective lens sections 210. The multiple curved reflective lens sections 210 are arranged circumferentially along the planar lens section 220. Further, the incident light surface 201 of each curved reflective lens section 210 is connected to the incident light surface 201 of two adjacent curved reflective lens sections 210, and the reflecting surface 202 of each curved reflective lens section 210 is connected to the reflecting surface 202 of two adjacent curved reflective lens sections 210. Further, the reflective portion of the planar lens section 220 surrounds the multiple curved reflective lens sections 210, and each incident light surface 201 is connected to a corresponding reflecting plane 203, and each reflecting surface 202 is connected to a corresponding reflecting plane 203. Further, the condensing lens section 230 is a polygonal annular condensing lens section. Furthermore, the number of softlights 100 is the same as the number of sides of the condenser lens section 230. Furthermore, the polygon formed by connecting the geometric center points of the projections of the light-emitting areas of every two adjacent softlights 100 onto the incident light surface 201 is proportionally transformed to the polygon formed by the outer edge of the condenser lens section 230. This improves not only the brightness of the softlights 100 but also the gradual softening of the formed light spot and the uniformity of the emitted light.

[0059] Please refer to the following: Figures 2 to 3In one embodiment, the soft flash structure 10 further includes a transition lens section 240. The transition lens section 240 has a transition light-incident surface 206 and a transition reflective surface 207 on opposite sides. A plurality of curved reflective lens sections 210 are arranged around the outer periphery of the transition lens section 240. The light-incident curved surface 201 of each curved reflective lens section 210 is connected to the transition light-incident surface 206, and the reflective curved surface 202 of each curved reflective lens section 210 is connected to the transition reflective surface 207. Further, the transition lens section 240, the curved reflective lens section 210, the planar lens section 220, and the focusing lens section 230 are integrally formed.

[0060] Please refer to the following: Figures 6 to 7 In one embodiment, the soft flash structure 10 further includes a flash unit 400 and a flash lens 500, the flash lens 500 being disposed on the side of the planar lens portion 220 near the light-gathering reflective surface 204. Further, please refer to... Figure 10 The light emitted by the flash 400 enters the flash lens 500 and exits through the reflective plane 203 of the planar lens portion 220, away from the focusing reflective surface 204. Furthermore, the planar lens portion 220 corresponding to the projection of the flash lens 500 onto the planar lens portion 220 is exposed to the light shield 300, thus achieving a better integration of flashing and soft lighting.

[0061] Please refer to the following: Figures 6 to 7 In one embodiment, the flash lens 500 has a flashing Fresnel pattern 209 on the side near the flash lamp 400. The apex angle of the groove of the flashing Fresnel pattern 209 is 47° to 52°, which better ensures the supplementary lighting effect at a distance of about 1m.

[0062] Please refer to the following: Figure 1 , Figure 6 and Figure 7 In one embodiment, the light shield 300 is provided with a flash avoidance hole 301. The planar lens portion 220 corresponding to the projection of the flash lens 500 onto the planar lens portion 220 is exposed in the flash avoidance hole 301. The reflective plane 203 on the side of the planar lens portion 220 away from the flash lens 500 is provided with a flash Fresnel pattern 209 and annular flash Fresnel pattern 209208. The flash Fresnel pattern 209 and annular flash Fresnel pattern 209208 are arranged around the hole wall of the flash avoidance hole 301, and the inner wall of the flash Fresnel pattern 209 and annular flash Fresnel pattern 209208 is flush with the side wall of the flash avoidance hole 301, thereby improving the flashing supplementary lighting effect.

[0063] Please refer to the following: Figures 2 to 3In one embodiment, a first reflective coating is attached to the peripheral wall of the condenser lens portion 230, and the first reflective coating is offset from the planar lens portion 220. It can be understood that if the condenser lens portion 230 is an annular condenser lens portion, that is, both the condenser reflective surface 204 and the light emitting surface 205 are annular, and the first reflective coating is connected to the outer peripheral wall of the light lens portion, it is beneficial to improve the light utilization rate of the flexible flash lamp 400.

[0064] Please refer to the following: Figures 2 to 3 In one embodiment, the focusing reflective surface 204 is provided with focusing Fresnel patterns. Further, the focusing reflective surface 204 is a focusing Fresnel wedge-shaped surface, and the focusing reflective surface 204 is disposed away from the curved reflective lens portion 210. Further, a second reflective coating is attached to the reflective curved surface 202. It can be understood that the reflective plane 203 is not provided with a coating for reflection; the reflective plane 203 relies on the reflective properties of the lens itself to achieve light reflection. Similarly, the focusing Fresnel patterns on the focusing reflective surface 204 are also not provided with a coating for reflection; relying on the reflective properties of the lens itself to achieve light reflection, the focusing Fresnel patterns change the angle of light reflection to achieve a focusing effect. Furthermore, the provision of the first and second reflective coatings effectively improves the reflectivity of light at the corresponding locations.

[0065] This application also provides a mobile phone. One embodiment of the mobile phone includes a back panel and a soft-light flash structure according to any of the above embodiments, with a light shield connected to the back panel and the light-emitting surface exposed on the back panel. Further details are also available in the following documents. Figures 1 to 4 In this embodiment, the soft flash structure 10 includes a soft flash 100, a soft lens 200, and a light shield 300. The soft lens 200 includes a curved reflective lens section 210, a flat lens section 220, and a focusing lens section 230 arranged in sequence. The curved reflective lens section 210 has an incident curved surface 201 and a reflective curved surface 202 on opposite sides, respectively. Both the incident curved surface 201 and the reflective curved surface 202 are curved away from the flat lens section 220. The flat lens section 220 has a reflective plane 203 on opposite sides, and the focusing lens section 230 has a focusing reflective surface 204 and a light-emitting surface 205 on opposite sides. The incident curved surface 201, one reflective plane 203, and the focusing reflective surface 204 are connected in sequence, and the reflective curved surface 202, the other reflective plane 203, and the light-emitting surface 205 are connected in sequence. The soft light 100, the curved reflective lens 210, the flat lens 220, and the focusing lens 230 are housed together within the light shield 300, with the light-emitting surface 205 exposed outside the light shield 300. The light emitted by the soft light 100 is at least partially incident on the incident curved surface 201 and reflected sequentially by the reflective curved surface 202, the two reflective planes 203, and the focusing reflective surface 204, and then emitted through the light-emitting surface 205.

[0066] The aforementioned mobile phone adopts a soft flash structure, which significantly improves the gradient softness and light uniformity of the light spot used for flexible fill light on the phone.

[0067] Compared with the prior art, the present invention has at least the following advantages:

[0068] The soft-light flash structure 10 of this utility model is such that the incident curved surface 201, one of its reflecting planes 203 and the focusing reflecting surface 204 are connected in sequence, and the reflecting curved surface 202, the other reflecting plane 203 and the light-emitting surface 205 are connected in sequence. This results in one side of the soft-light lens 200 being composed of the incident curved surface 201, one reflecting plane 203 and the focusing reflecting surface 204 connected in sequence, and the other side being composed of the reflecting curved surface 202, the other reflecting plane 203 and the light-emitting surface 205 connected in sequence. Both the incident curved surface 201 and the reflecting curved surface 202 face away from the light source. The plane lens section 220 is curved so that the light emitted by the soft light lamp 100 enters at least part of the incident light curved surface 201 and passes through the curved surface reflecting lens section 210. This causes more of the light emitted by the soft light lamp 100 to enter the plane lens section 220 at an inclined angle and to be reflected at least partly between the two reflecting surfaces 203 of the plane lens section 220 and propagate in a direction away from the curved surface reflecting lens section 210 to the incident light focusing lens section 230. The light focusing lens section 230 focuses and reflects the incident light through the light focusing reflecting surface 204 and emits it from the light emitting surface 205, thus realizing the formation of a gradually softened light spot with better light uniformity.

[0069] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
