Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to a structure for a dual-beam (high and low beam) flashlight and a mobile phone. Background Technology

[0002] Flashlights are a common tool for supplementing light and can improve the brightness and clarity of photos in safe environments. However, the illumination distance of many flashlights is limited. For example, the utility model patent application with application number CN 202021079164.5 proposes that a mobile phone's high- and low-light flash includes a first flash and a second flash that can emit high beam and low beam respectively. By controlling the on / off state of the first flash and the second flash, close-range and long-range supplementary lighting can be achieved. However, this requires two flashlights to be installed inside the mobile phone, which is not suitable for the miniaturization requirements of mobile phones. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flash structure and mobile phone that can achieve both near-distance and long-distance supplementary lighting and can be miniaturized into a two-in-one flash for both near and long-distance beams.

[0006] The integrated high and low beam lens includes a low beam lens and a high beam lens connected together. The incident surface and the exit surface of the low beam lens are arranged side by side, corresponding one-to-one with the incident surface and the exit surface of the low beam lens. Light emitted from one of the light sources enters the low beam lens and exits through the low beam lens, while light emitted from the other light source enters the high beam lens and exits through the high beam lens.

[0007] In one embodiment, the low-beam lens and the high-beam lens are integrally formed.

[0008] In one embodiment, the thickness of the low-light lens is 2mm to 5mm.

[0011] In one embodiment, the apex angle of the Fresnel grooves of the near-light lens is 46° to 49°.

[0012] In one embodiment, the high beam lens is a Fresnel high beam lens.

[0013] In one embodiment, the apex angle of the Fresnel grooves of the high beam lens is 38° to 42°.

[0014] In one embodiment, the high beam lens and the low beam lens are mirror images of each other and spliced ​​together to form a semi-circular rectangular structure. The center of one half of the semi-circular rectangular structure is located on the optical axis of the high beam lens, and the center of the other half of the semi-circular rectangular structure is located on the optical axis of the low beam lens.

[0015] In one embodiment, the outer side length of the rectangle of the semicircular rectangular structure is 1 / 3 to 4 / 5 of the radius of the semicircle of the semicircular rectangular structure.

[0016] In one embodiment, the geometric center of the region where one of the light sources emits light is located on the optical axis of the telephoto lens.

The projection of the area of ​​light emitted by each light source on the glass cover plate is located at the light emission area, and the light shielding area is arranged around the light emission area.

[0019] A mobile phone includes a mounting frame and a high / low beam dual-flash structure as described in any of the above embodiments, wherein each of the light sources is connected within the mounting frame.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] This utility model's high / low beam dual-beam flash structure connects the low beam lens and the high beam lens, with the incident and exit surfaces of the low beam lens arranged side-by-side in a one-to-one correspondence with those of the high beam lens. This ensures that the incident and exit surfaces of the low beam and high beam lenses face the same direction, and vice versa.

[0032] This application provides a combined high / low beam flash structure. The aforementioned combined high / low beam flash structure includes two parallel light sources and an integrated high / low beam lens. The integrated high / low beam lens includes a connected low beam lens and a high beam lens. The incident and exit surfaces of the low beam lens correspond one-to-one with the incident and exit surfaces of the high beam lens, arranged side-by-side. Light emitted from one light source enters and exits through the low beam lens, while light emitted from the other light source enters and exits through the high beam lens.

[0033] The aforementioned high / low beam combined flash structure connects the low beam lens and the high beam lens, with the incident and exit surfaces of the low beam lens arranged side-by-side in a one-to-one correspondence with those of the high beam lens. This ensures that the incident and exit surfaces of the low beam and high beam lenses face the same direction, and vice versa. This allows light from one light source to enter and exit through the low beam lens, while light from the other light source enters and exits through the high beam lens. This effectively enables the high / low beam combined flash structure to provide both close-range and long-range fill light, and also achieves a good degree of miniaturization.

[0034] To better understand the structure of the high / low beam combined flash unit of this application, the following further explanation is provided:

[0035] Please refer to the following: Figure 1 , Figure 2 and Figure 4 One embodiment of the high / low beam combined flash structure 10 includes an integrated high / low beam lens 200 and two side-by-side light sources 100. The integrated high / low beam lens 200 includes a low beam lens 210 and a high beam lens 220 connected to each other. The incident surface a1 and the exit surface a2 of the low beam lens 210 correspond one-to-one with the incident surface b1 and the exit surface b2 of the low beam lens 210 and are arranged side-by-side. Light emitted from one of the light sources 100 enters the low beam lens 210 and exits through the low beam lens 210, while light emitted from the other light source 100 enters the high beam lens 220 and exits through the high beam lens 220.

[0036] The aforementioned high / low beam combined flash structure 10 connects the low beam lens 210 and the high beam lens 220, with the incident and exit surfaces of the low beam lens 210 corresponding one-to-one and arranged side-by-side. This ensures that the incident surfaces of the low beam lens 210 and the high beam lens 220 face the same direction, and the exit surfaces of the low beam lens 210 and the high beam lens 220 also face the same direction. This allows light emitted from one light source 100 to enter and exit the low beam lens 210, while light emitted from the other light source 100 enters and exits the high beam lens 220. This effectively enables the high / low beam combined flash structure 10 to provide both close-range and long-range fill light, and also achieves a good miniaturization of the high / low beam combined flash structure 10.

[0037] Please refer to the following: Figures 2 to 4 In one embodiment, the low beam lens 210 and the high beam lens 220 are integrally formed. This integral formation improves the structural compactness of the integrated low and high beam lens 200 and facilitates the coordinated installation of the two lenses, thereby further miniaturizing the high and low beam combined flash structure 10. Furthermore, the compact, integrally formed design of the low beam lens 210 and the high beam lens 220 allows light emitted from one light source 100 to enter the low beam lens 210 and partially enter the high beam lens 220, while light emitted from the other light source 100 enters the high beam lens 220 and partially enters the low beam lens 210, effectively improving the utilization rate of the light source 100.

[0038] Please refer to the following: Figures 2 to 4 In one embodiment, the low-beam lens 210 is a Fresnel low-beam lens. Further, the apex angle c1 of the Fresnel grooves in the low-beam lens 210 is 46°–49°. Further, the high-beam lens 220 is a Fresnel high-beam lens. Further, the apex angle c2 of the Fresnel grooves in the high-beam lens 220 is 38°–42°. Further, the thickness of the low-beam lens 210 is 2mm–5mm. Further, the thickness of the high-beam lens 220 is 0.5mm–2mm, which effectively ensures both the near-field illumination effect of the low-beam lens 210 and the long-field illumination effect of the high-beam lens 220.

[0039] Please refer to the following: Figure 2 , Figure 4 , Figure 6In one embodiment, the high-beam lens 220 and the low-beam lens 210 are mirror-distributed and spliced ​​together to form a semi-circular rectangular structure 200A. The center of one half-circle d1 of the semi-circular rectangular structure 200A is located on the optical axis of the high-beam lens 220, and the center of the other half-circle d1 of the semi-circular rectangular structure 200A is located on the optical axis of the low-beam lens 210. Further, the outer side length of the rectangle d2 of the semi-circular rectangular structure 200A is 1 / 3 to 4 / 5 of the radius of the half-circle d1 of the semi-circular rectangular structure 200A. Further, the geometric center of the area emitting light from one light source 100 is located on the optical axis of the high-beam lens 220. Further, the geometric center of the area emitting light from the other light source 100 is located on the optical axis of the low-beam lens 210, which optimizes the light distribution and makes the combined high-beam and low-beam flash structure 10 better adaptable to the needs of long-distance and short-distance supplementary lighting in various scenarios.

[0040] Please refer to the following: Figure 1 , Figure 2 and Figure 5 In one embodiment, the high / low beam combined flash structure 10 further includes a glass cover plate 300. The glass cover plate 300 is disposed opposite to the emission surfaces of the high beam lens 220 and the low beam lens 210, respectively. The glass cover plate 300 is provided with a light-emitting area 301 and a light-shielding area 302. The projection of the area emitting light from each light source 100 onto the glass cover plate 300 is located at the light-emitting area 301. The light-shielding area 302 is arranged around the light-emitting area 301, ensuring high light transmittance of the high / low beam combined flash structure 10 and reducing stray light. Furthermore, part of the light emitted from the emission surfaces of the high beam lens 220 and the low beam lens 210 is emitted through the light-emitting area 301, and another part of the light emitted from the emission surfaces of the high beam lens 220 and the low beam lens 210 is blocked by the light-shielding area 301.

[0041] This application also provides a mobile phone. The mobile phone includes a mounting frame and a high / low beam dual-flash structure according to any of the above embodiments, with each light source connected within the mounting frame. Further, in this embodiment, the high / low beam dual-flash structure 10 includes two parallel light sources 100 and a high / low beam integrated lens 200. The high / low beam integrated lens 200 includes a connected low beam lens 210 and a high beam lens 220. The incident and exit surfaces of the low beam lens 210 correspond one-to-one with the incident and exit surfaces of the low beam lens 210, arranged in parallel. Light emitted from one light source 100 enters and exits through the low beam lens 210, while light emitted from the other light source 100 enters and exits through the high beam lens 220.

[0042] The aforementioned mobile phone adopts a dual-beam flash structure that combines high and low beams, enabling it to provide both close-range and long-range fill light functions, and also contributing to the miniaturization of the phone.

[0043] Compared with the prior art, the present invention has at least the following advantages:

[0044] The present invention relates to a combined high and low beam flash structure 10, in which a low beam lens 210 and a high beam lens 220 are connected, and the incident and exit surfaces of the low beam lens 210 are arranged side by side in a one-to-one correspondence with the incident and exit surfaces of the high beam lens 220, so that the incident surfaces of the low beam lens 210 and the high beam lens 220 face the same direction, and the exit surfaces of the low beam lens 210 and the high beam lens 220 also face the same direction. This allows light emitted from one light source 100 to enter and exit the low beam lens 210, and light emitted from the other light source 100 to enter and exit the high beam lens 220. Thus, the combined high and low beam flash structure 10 effectively achieves both close-range and long-range supplementary lighting, and also achieves a good miniaturization of the combined high and low beam flash structure 10.
