At present, a front camera of a mobile terminal is generally not provided with a flash lamp, but the pixel size of a camera sensor is reduced along with the improvement of the resolution of the front camera, and under the relatively dark photographing environment of light, even if a screen of the mobile terminal performs light supplement, a self-timer can hardly obtain a good self-timer effect. In the prior art, some mobile terminals are individually provided with the front-mounted flash lamp, but the use area of the existing screen is lost, certain screen occupation ratio cannot be guaranteed, the size design of the front-mounted flash lamp is very limited, and the illumination effect and the heat dissipation problem cannot be well solved. Therefore, on the premise of not losing the screen occupation ratio, increasing the light supplement when the front camera takes a picture is a problem to be solved urgently at present
The first embodiment is as follows:
as shown in fig. 1, the present invention provides a front-mounted flash device of a mobile terminal, which is arranged at a receiver hole 100 of the mobile terminal, and takes a direction of the receiver hole 100 of the mobile terminal as a front side, a direction of the receiver hole 100 deviating from the mobile terminal as a back side, and four sides of the mobile terminal, i.e., an upper side, a lower side, a left side, and a right side.

Through the setting, the light that light emitting component 400 sent passes through printing opacity subassembly 300 conducts extremely listening cylinder hole 100 can listen cylinder hole 100 regional design diffuse reflector, with light diffuse reflection, effectively promote screen light filling effect for light is softer, does not influence the screen and accounts for, also does not have the problem that generates heat simultaneously.
In the above scheme, the light guide frame 200 is disposed inside the earpiece hole 100, and the light-transmitting component 300 is disposed in the glue groove 210 by disposing the light guide frame 200 on the back side of the earpiece hole 100, and the light-emitting component 400 is disposed in the glue groove 210 and located on the side of the light-transmitting component 300, and the light-emitting component 400 is connected to the light-transmitting component 300, so that light is transmitted to the earpiece hole 100 through the light-transmitting component 300. Simultaneously can listen the regional diffuse reflector of design of bobbin hole 100, with light diffuse reflection, effectively promote the screen light filling effect for light is softer, does not influence the screen and accounts for the ratio, also does not have the problem that generates heat simultaneously, makes under the prerequisite that does not lose the screen and accounts for the ratio, increases the light filling problem when leading camera shoots, increases mobile terminal's market competition.
Specifically, the light guide frame 200 is square, the light guide frame 200 is used for bearing and assembling the light transmitting assembly 300 and the light emitting assembly 400, one side of the glue groove 210 away from the light emitting assembly 400 can be slightly wider than one side of the glue groove close to the light emitting assembly 400, and the shape of the glue groove 210 can also be set according to the requirements of the light emitting assembly 400 and the light transmitting assembly 300. Specifically, a first groove 220 is further disposed on one side of the light guide frame 200 facing the earpiece, the first groove 220 is disposed on one side of the glue groove 210 facing the earpiece hole 100, the shape of the first groove 220 is the same as that of the glue groove 210, a notch of the first groove 220 is larger than that of the glue groove 210, the first groove 220 is communicated with the glue groove 210, the first groove 220 is used for placing the light shielding ring 340 in the light emitting element 400, and further, in order to ensure a light shielding effect of the light shielding ring 340 at the light source of the light emitting element 400, a side wall of the first groove 220 facing one side of the light emitting element 400 and a side wall of the glue groove 210 facing one side of the light emitting element 400 are on the same plane. Further, a first opening groove 230 is disposed inside the glue groove 210 and on a side close to the light emitting assembly 400, and the first opening groove 230 facilitates connection of a connector 430 of the light emitting assembly 400 with a power supply.
As shown in fig. 1, in the structure of the specific embodiment of the present invention, the light-transmitting assembly 300 includes: the reflective film 310 is disposed at the bottom of the glue groove 210, the reflective film 310 is square, and a corner of the reflective film 310 may be provided with a chamfer, so as to facilitate installation of the reflective film 310. The reflective film 310 is used to reflect the light emitted from the light guide plate 320 of the light transmission assembly 300 back, so as to improve the utilization rate of the light and increase the brightness of the light.
Specifically, when light is projected onto the surface of the reflective film 310, most of the light is reflected from the surface because the opacity of the reflective film 310 is more than 99%. The incident light and the reflected light of the reflective film 310 correspond to each other one-to-one, and the specular reflection occurs, and the higher the glossiness of the surface of the reflective film 310 is, the higher the reflectivity is. Further, the reflective film 310 may use a single-layer structure reflective film 310, a double-layer structure reflective film 310, and a triple-layer structure reflective film 310. The cross section of the single-layer structure reflective film 310, i.e., the whole film, is uniform, the single-layer structure reflective film 310 has a high density, and a large amount of inorganic additives are added to the single-layer structure reflective film to form a light-tight effect, thereby playing a role in surface reflection. The cross section of the three-layer reflective film 310 can be divided into a core layer and an upper surface layer and a lower surface layer, the three-layer reflective film 310 generally has a low density, the density is reduced by adding an olefin material with a low density or adding a foaming material into the core layer, the surface layer generally adopts pure polyester or properly adds a part of inorganic particles to improve the surface glossiness and the reflectivity, and the three-layer reflective film 310 generally has a high reflectivity. The structure of the two-layer reflective film 310 is similar to that of the three-layer reflective film 310, and compared with the three-layer reflective film 310, the two-layer reflective film 310 has one less surface layer and has a lower reflectivity than the three-layer reflective film 310.
As shown in fig. 1, in the structure of the specific embodiment of the present invention, the light-transmitting assembly 300 further includes: the light guide plate 320 is disposed in the glue groove 210 and on a side of the reflective film 310 away from the bottom of the glue groove 210, and the light guide plate 320 is connected to the reflective film 310. The light guide plate 320 is used for changing the direction of the light source and uniformly guiding the light source out. Specifically, the light guide plate 320 is square, and a corner of the light guide plate 320 may be provided with a chamfer, so as to facilitate installation of the light guide plate 320.
Specifically, the light guide plate 320 is formed by printing light guide points on the bottom surface of an optical acrylic plate by using optical acrylic or PC plate and using a high-tech material with a very high refractive index and no light absorption, and by using laser engraving, V-shaped cross grid engraving, UV screen printing and other techniques; the optical acrylic sheet absorbs the light emitted from the lamp to stay on the surface of the optical acrylic sheet, and when the light reaches each light guide point, the reflected light is diffused at each angle, and then the reflected light is emitted from the front surface of the light guide plate 320 by destroying the reflection condition. The light guide plate 320 can uniformly emit light through various light guide points with different densities and sizes.
