Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1, in the prior art, after a light 20 is emitted from a light source 10 disposed on one side of a screw, since a reflection surface (i.e., a top surface) of the screw is a plane, the light 20 obliquely irradiates the reflection surface of the screw and is then totally reflected at a large angle, that is, an included angle between an incident light 20 and an emergent light 20 is formed to be large, so that the amount of the light 20 reflected above the reflection surface of the screw is small, and a shadow 200 phenomenon appears on a display screen, that is, the problems of uneven display and poor display quality of an intelligent display device are caused. To solve the technical problem, the present application proposes an improved light reflection structure 100.

As shown in fig. 2, a light reflection structure 100 shown in an embodiment of the present application is specifically a constituent structure of a display module of an intelligent display device (such as any one of a mobile phone, a television, a tablet, a notebook computer, etc.), and is used for implementing information display.

Illustratively, the light reflecting structure 100 includes: a light source 10 and a fastener 40. The light source 10 is used for emitting light 20 to illuminate the screen and adjust the display brightness of the screen. Alternatively, the light source 10 may be an LED lamp, which has the advantages of energy saving and consumption reduction.

The fastening member 40 is used to fix other constituent elements of the display module. For example, the fastener 40 is used to fix the light bar.

Optionally, in some embodiments, the fastener 40 is provided as a threaded connection. The threaded connecting piece is installed in a threaded connection mode, and is simple in structure, convenient and labor-saving to assemble and disassemble. When carrying out the lamp strip installation, with the screw hole counterpoint of predetermineeing through-hole and support on the lighting fixture of lamp strip, then pass through the through-hole with threaded connection spare after screw up in the screw hole can.

Further, in order to facilitate the handling of the assembly personnel, in some embodiments the threaded connection is provided as a screw. For example, the screws are thumbscrews. The dish loading operation can be carried out without special auxiliary tools, and the dependence on tools is reduced.

It should be noted that, in other embodiments, the fastening member 40 may be any one of a magnetic member, an adhesive member, a snap member, and the like, instead of the above-mentioned threaded connecting member, to implement mounting and fixing of the light bar. Specifically, the fastening member 40 is a magnetic member (e.g., a magnet) embedded in the slot of the bracket, and the light bar is fixed by being attracted to the lamp holder of the light bar. When dismantling the lamp strip, overcome magnetic attraction and directly extract the lamp strip can.

A light exit surface 30 is defined above the light source 10. It can be understood that the light exit surface 30 is a plane on which the screen is located. The fastening member 40 is disposed at one side of the light source 10 and within the range of the light emitting surface 30, a reflective structure 41 is formed on a reflective surface of the fastening member 40, and the reflective structure 41 is used for increasing the amount of the light 20 reflected to the light emitting surface 30 above the fastening member 40.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: in the light reflection structure 100 of the above-mentioned solution, the fastening element 40 is disposed at one side of the light source 10, and both the light source 10 and the fastening element 40 are located in the range below the light emitting surface 30. Because the reflecting surface of the fastening member 40 is formed with the reflecting structure 41, when the light 20 emitted from the light source 10 irradiates the reflecting surface of the fastening member 40, the reflecting structure 41 can reduce the total reflection angle of the light 20, so as to increase the amount of the light 20 reflected from the upper side of the fastening member 40, thereby well solving the problem that the phenomenon of the black shadow 200 appears on the light emitting surface 30, ensuring a better display effect, and avoiding influencing the use experience of a client and the product quality.

With reference to fig. 3, on the basis of the above embodiment, the light reflecting structure 41 is optionally configured as a convex lens 411. The arc convex surface of the convex lens 411 has a more uniform reflection effect on the incident light 20 emitted from the light source 10, so that the effect of reducing the total reflection angle of the light 20 can be achieved, the amount of the reflected light 20 above the screw can be increased, and the problem of the real shadow 200 can be solved.

Specifically, the convex lens 411 in this embodiment is a non-planar structure formed on the reflective surface of the fastening element 40 by machining, chemical etching, or other processes. Of course, the light reflecting structure 41 in other embodiments may be other regular or irregular structures capable of reducing the total reflection angle of the light beam 20, and may be selected according to actual needs.

In some embodiments, the light reflecting structure 41 is distributed on a partial area or a whole area of the reflecting surface of the fastening member 40.

When the reflective structure 41 is distributed on the whole area of the reflective surface of the fastening member 40, the total reflection angle can be reduced, and the light 20 can be emitted more uniformly; when the reflective structure 41 is distributed in a local area of the reflective surface of the fastening member 40, on the basis of reducing the total reflection angle of part of the light 20, the reflective structure 41 can perform large-angle total reflection on the rest of the light 20 at the reflective surface part not covered by the reflective structure 41, and the reflective structure and the rest of the light 20 can increase the emitting area of the light 20 by matching, so that the reflected light 20 can completely cover the light-emitting surface 30, and the display effect is ensured.

Specifically, when the light reflecting structure 41 is only distributed in a local area of the reflecting surface of the fastening member 40, the light reflecting structure may be located at a central position of the reflecting surface, or may be located at an eccentric position of the reflecting surface, which is specifically selected according to actual needs. Preferably, the light reflecting structure 41 is disposed at a central position of the reflecting surface of the fastener 40.

In addition, on the basis of any of the above embodiments, the light reflecting structure 41 is provided with a plurality of convex lenses 411, and the plurality of convex lenses 411 are arranged on the reflecting surface of the fastening member 40 in an array or non-array structure. Set up a plurality of convex lens 411 simultaneously, can strengthen the effect that reduces to light 20 total reflection angle to make more light 20 can be gone out from the top reflection of screw.

According to practical requirements, the convex diameters of the convex lenses 411 are the same in the embodiment; or the convex diameters of the convex lenses 411 are not completely the same; or the convex diameters of the convex lenses 411 are all different. Therefore, the requirement on product diversity can be met, the machining size error in a certain range is allowed, and the machining difficulty of the product is reduced.

Illustratively, the convex diameters of the convex lenses 411 are designed to be the same size, and the convex lenses 411 are distributed on the circular reflecting surface of the screw and arranged in a uniform array. Alternatively, the diameters of the convex surfaces of the convex lenses 411 are all the same, but are increased progressively according to a predetermined rule, for example, the difference between the diameters of the convex surfaces of two adjacent convex lenses 411 is 1mm. The respective convex lenses 411 are arranged in a spiral type, a meander type, etc.

Further, on the basis of the above embodiment, a plurality of convex lenses 411 are distributed in a partial area or a total area of the reflection surface of the fastening member 40. When the plurality of convex lenses 411 are distributed in the whole area of the reflecting surface of the fastener 40, the total reflection angle can be reduced, and the light 20 can be emitted more uniformly; when the plurality of convex lenses 411 are distributed in the local area of the reflection surface of the fastening member 40, the reflection structure 41 can perform large-angle total reflection on the rest of the light 20 on the basis of reducing the total reflection angle of the part of the light 20, and the reflection surface part not covered by the reflection structure 41 can perform large-angle total reflection on the rest of the light 20, so that the emission area of the light 20 can be increased by matching the reflection structure and the rest of the light, the reflection light 20 can completely cover the light-emitting surface 30, and the display effect is ensured.

Specifically, when the plurality of light reflecting structures 41 are distributed only in a local area of the reflecting surface of the fastening member 40, the light reflecting structures may be located at the center of the reflecting surface, or may be located at an eccentric position of the reflecting surface, which is specifically selected according to actual needs. Preferably, a plurality of light reflecting structures 41 are disposed at a central position of the reflecting surface of the fastening member 40.

In some embodiments, the reflective surface of the fastener 40 is provided as a flat surface; or the reflecting surface of the fastener 40 is arranged to be an outer convex cambered surface; or the reflecting surface of the fastening member 40 is provided as a concave arc surface. The screws with different structures can meet the use requirements of the light reflection structure 100, so that the total reflection angle of the light 20 is reduced, and the problem of displaying the shadow 200 is solved.

It should be noted that the light reflecting structure 100 in other embodiments may be other structures besides the convex lens, which can achieve the effect of reducing the total reflection angle. For example, the light reflecting structure 100 may be a concave mirror, a triangular prism, or other irregular optical structure.

It should be noted that, in other embodiments, the fastening member 40 may be other components besides screws, which can be used to fix the light bar. Such as fasteners 40 being pins, rivets, clamps, etc.

Furthermore, in other embodiments, the light reflecting structure 41 is provided as a light reflecting member, and the light reflecting member is attached to the reflecting surface. By installing an independent reflector on the reflecting surface, the reflector can also reduce the total reflection angle of the light 20, thereby eliminating the phenomenon of displaying the black shadow 200. Specifically, the light reflecting member may be any one of, but not limited to, a reflective film, a reflective label, a mirror, and the like. When the light reflecting piece is installed, the light reflecting piece can be fixed in any one of the connection modes of bonding, screw connection, clamping, magnetic attraction and the like, and can be selected according to actual needs.
