Further, said eyeglass specifically is to be formed by the convex lens distortion; Wherein, first of said eyeglass is the plane, and second face comprises center sphere and a plurality of concentric ring cambered surface; Said center sphere and a plurality of concentric ring cambered surface can constitute the convex surface of said convex lens after translation is also end to end.
Preferably, said light source is positioned at a side of second of said eyeglass.
Preferably, said eyeglass is processed by optical plastic.
Preferably, said eyeglass is processed through Shooting Technique.
Preferably, said light source is positioned at the along of said convex lens.
Preferably, said light source be light emitting diode (Light Emitting Diode, LED).
A kind of portable terminal comprises camera and above-mentioned flash lamp.
A kind of manufacturing approach of flash lamp comprises:
Design the profile of the convex lens in the said flash lamp;
Said convex lens are out of shape, form the model of the eyeglass of said flash lamp;
According to the model of said eyeglass, exploitation is also made the precise injection molding mould;
Utilize the eyeglass of the said flash lamp of said precise injection molding die production;
With said eyeglass and light source assembling, form said flash lamp.
Wherein, said said convex lens are out of shape, form the model of the eyeglass of said flash lamp, specifically comprise:
Successively find out the part that does not influence light path in the said convex lens;
Remove the said part that does not influence light path, and remainder is moved to the bottom of said convex lens, form the model of the eyeglass of said flash lamp.
Compared with prior art; Technique scheme provided by the present invention has following advantage: with convex lens as the flash lamp eyeglass; Can assemble the light that the light source of flash lamp sends; Light is converged in the small range, thereby the brightness of increase illumination is improved the image quality of camera.
Description of drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the invention; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the flash lamp that embodiments of the invention provided;
Fig. 2 is the manufacturing approach flow chart of the flash lamp that embodiments of the invention provided;
Fig. 3 is the sketch map of the design process of the eyeglass of the flash lamp that embodiments of the invention provided.
The specific embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not paying creative work belongs to the scope that the present invention protects.
Flash lamp as shown in Figure 1, that the embodiment of the invention provided comprises light source 1 and is positioned at the eyeglass 2 on the light path of light source 1 that this eyeglass 2 is convex lens.
As flash lamp eyeglass 2, can assemble the light that the light source 1 of flash lamp sends with convex lens, light is converged in the small range, thereby increase the brightness of illumination, the image quality of camera is improved.
As a preferred version, this eyeglass 2 specifically is to be formed by the convex lens distortion; As shown in Figure 1, first of eyeglass 2 is the plane, and second face comprises center sphere and a plurality of concentric ring cambered surface; Said center sphere and a plurality of concentric ring cambered surface can constitute the convex surface of convex lens after translation is also end to end.In fact, this structure of eyeglass 2 successively " is subsided " distortion by convex lens and is formed.
Because the volume of portable terminal such as mobile phone, MP4 is all very little; The space that is used to place flash lamp is limited; And convex lens are carried out " subsiding " distortion; Can under the prerequisite that does not influence spotlight effect, significantly reduce the volume and weight of eyeglass, the demand of flash lamp and portable terminal miniaturization is adapted.
As shown in Figure 2, the concrete implementation method of the flash lamp that the embodiment of the invention provides may further comprise the steps:
S1: the size situation actual according to portable terminal, the radius and the focal length of design convex lens, and utilize simulation software such as CAD to produce the profile of convex lens.
S2: as shown in Figure 3, utilize software such as CAD that convex lens are carried out " subsiding " distortion, form the model of the eyeglass of flash lamp.
Concrete, the convex lens that Fig. 3 a designs for above-mentioned steps S1.
Shown in Fig. 3 b, successively find out the part (dash area among the figure) that does not influence light path in the convex lens, these parts were actually by a plurality of overlapping more flat cylindrical compositions.
Shown in Fig. 3 c, remove the above-mentioned part that does not influence light path, and remainder is moved to the bottom of lens, form the lens shown in Fig. 3 d.
S3: according to the model of above-mentioned eyeglass, exploitation is also made the precise injection molding mould.
S4: as raw material, utilize above-mentioned precise injection molding Mold Making eyeglass with optical plastic, utilize conventional injection moulding process can produce the eyeglass of this flash lamp in batches.
S5:, form flash lamp with component-assembled such as eyeglass of producing and light sources.
When assembling, can light source be placed on second one side of eyeglass.Just be exposed the plane of eyeglass (first face); The center sphere of while the inside (second face) and the texture that the concentric ring cambered surface is had also can make the user can't see the inner circuit board of mobile phone; And eyeglass itself can not influence light transmittance; Make flash lamp not only attractive in appearance, also have good light transmittance and spotlight effect.
In the embodiment of the invention, can use the light source of light emitting diode (LED), preferably, can LED be placed on the along of eyeglass, so just can the light that LED sends be pooled directional light as flash lamp.Certainly, in practical application, can suitably regulate the position relation of light source and eyeglass focus, to regulate the intensity of illumination range and light.
The embodiment of the invention also provides a kind of portable terminal, can be products such as mobile phone or MP4 specifically, and this portable terminal comprises the flash lamp in camera and the foregoing description.
Because the portable terminal that the embodiment of the invention provides has identical technical characterictic with the flash lamp that the foregoing description is provided, so also can produce identical technique effect, solves identical technical problem.
The above; Be merely the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
