An aspect of of the present present invention is to provide a kind of flash module with light guide that is used for mobile terminals, and this flash module comprises: the Lights section is used to produce light; Light guide, the one end is attached to the Lights section, makes light diffusion and the deflection equably from the Lights section radiation, to be transmitted into the other end; Lens component is arranged in the described other end position adjacent with light guide, the light that is launched with outside propagation.
The Lights section has a kind of as light source in fluorescent lamp, cathodoluminescence phosphorescent lamp, light-emitting diode (LED), Organic Light Emitting Diode (OLED) or the luminescence of plasma system (PLS).
Light guide is by a kind of the making in polymethyl methacrylate, Merlon and the glass.The surface-coated of light guide has a kind of in silver, aluminium, nickel and the titanium.The cross section of light guide is rounded, ellipse or polygon.Light guide has the reflecting surface that is used to make from the light deflection of the Lights section radiation.
Light source and light guide can form as one, and light guide and lens component can form as one, and perhaps light source, light guide and lens component can form as one.
Beneficial effect
As mentioned above, according to the present invention, owing to used light guide at the flash module that is used for mobile terminals, thus be radiated light quilt diffusion and the deflection equably in the light guide, thus light can be transmitted into flash-o-lens effectively, causes better optical efficiency.Therefore, the illumination angle of camera can be set to the visual angle corresponding to camera.

Embodiment
Below, will describe exemplary embodiment of the present invention in detail.But, the invention is not restricted to the exemplary embodiment of following discloses, but can realize with various forms.So, provide these exemplary embodiments to be intactly openly the present invention, and scope of the present invention informed those of ordinary skill in the art comprehensively.
Now, server according to the formation broadcast content management system of exemplary embodiment of the present invention is described with reference to the accompanying drawings.
Fig. 2 and Fig. 3 have shown the flash module with light guide that is used for mobile terminals according to an exemplary embodiment of the present invention.Fig. 4 is the perspective view that the mobile terminals that has the flash module that has light guide according to an exemplary embodiment of the present invention is shown.Fig. 5 has shown the result of experiment of the optical efficiency that is used for measuring the mobile terminals with traditional flash module, and Fig. 6 has shown the result of experiment of the optical efficiency that is used for measuring the mobile terminals with flash module of the present invention.
With reference to Fig. 2 and Fig. 3, the flash module with light guide that is used for mobile terminals comprises: the Lights section 21 is used to launch light; Light guide 23 makes end diffusion and the deflection equably of passing through this light guide 23 from the light of the Lights section 21 radiation, to launch towards its other end; Lens component 25 is positioned at the other end of optical waveguide, so that light is propagated into the outside from light guide 23.
The Lights section 21 comprises light source 213 and source reflection part, and light source 213 is positioned at the core of the Lights section 210.
Can use fluorescent lamp, cathodoluminescence phosphorescent lamp, light-emitting diode (LED), Organic Light Emitting Diode (OLED) or luminescence of plasma system (PLS) as light source 213.PLS is the light source of new ideas, wherein, uses the plasma light principle of luminosity by using microwave.The principle of PLS is: have predetermined gas injection chamber wherein, the microwave and the gas atom that produce in magnetron bump, and become highly ionized plasmoid, thereby luminous.
The light that the source reflection part is sent from light source 213 towards the internal reflection of light guide 23, thus optical efficiency improved.For this reason, the source reflection part is made by the material of high reflectance, and can coated silver (Ag).
Light guide 23 can be by a kind of the making in polymethyl methacrylate (poly methyl meta acrylate), Merlon (poly carbonate) and the glass.
Light guide 23 is made by transparent acrylic resin (for example, polymethyl methacrylate (PMMA)), and have the tube shape of hollow usually.The intensity height of PMMA, distortion hardly, and to the visible light transmittance height.
Light guide 23 is designed to make and shines its inner light by total reflection continuously.
Preferably, a kind of in the coated silver in whole surface, aluminium, nickel and the titanium of light guide 23.In addition, light guide 23 made of aluminum can coated silver (Ag), then in order to prevent that it is owing to heat is out of shape coated titanium once more.
If the whole surface of light guide 23 is metal coated, the light that then is radiated light guide 23 can outwards not launched, but is transmitted into the lens component 25 that is positioned on its other end, thereby makes the minimization of loss of light.
Light guide 23 has tubular, and this tubular cross section is rounded, ellipse and polygon, and the shape in this cross section can change according to the type of mobile terminals and the position of flash module.Light guide 23 can also comprise and is used to make the reflecting surface that deflects from the light of the Lights section 21 radiation.As shown in Figures 2 and 3, be used to make the L shaped inner edge surface of the light guide 23 that light deflects as light reflective surface 233.
Preferably the angle of reflecting surface 233 is defined as making light to be launched with illumination angle corresponding to the visual angle of camera.
Recently, the mobile terminals very thin and small size that is tending towards becoming.In Fig. 4, components apart ground is arranged, but in order to make the mobile terminals very thin and undersized purpose that becomes, the Lights section 21 and light guide 23 can form as one, light guide 23 and lens component 25 can form as one, perhaps the Lights section 21, light guide 23 and lens component 25 threes can form as one, and this depends on the type of mobile terminals.
Fig. 5 and Fig. 6 can confirm effect of the present invention.As shown in Figure 5, in the mobile terminals with traditional flash module, light concentrates on core, is launched out then.On the contrary, as shown in Figure 6, in having the mobile terminals of flash module of the present invention, light is not concentrated, but distributes equably, is launched out then.Optical efficiency (light efficiency) with mobile terminals of traditional flash module is 45.6%, and the optical efficiency with mobile terminals of flash module of the present invention is 53.7%.
Though shown and described certain exemplary embodiments of the present invention, it should be appreciated by those skilled in the art, under the situation that does not break away from the principle and scope of the present invention that are defined by the claims, can carry out the various changes of form and details to it.
