SUMMARY OF THE INVENTION The present invention is directed to an illumination module and an electronic device having the illumination module for providing a pattern of illumination contours. The invention of the invention provides a lighting module comprising at least one first substrate, a second substrate and a plurality of light sources. The surface light sources of the second substrate stacked on the first substrate are respectively located at opposite sides of the first substrate, and the light sources face each other directly toward all (4) of the second substrate, thereby displaying the light by using the 3 201250642 light reflection mode. The light-emitting profile of the two substrates. In one embodiment of the invention, the face of the single first substrate is divided into a first region and a second region. The second substrate is stacked on the surface of the first substrate and completely covers the first region. In addition, the light emitting module further comprises an opaque layer. The opaque layer is disposed on the surface of the first substrate and completely covers the second region. The opaque layer can be, for example, an opaque gel, tape, dyed coating, bond layer or printed matter. In another embodiment of the present invention, the area occupied by the second substrate stacked on the first substrate is equal to the area of the first substrate. In one variation of each of the above embodiments, the first substrate is a plastic transparent plate, and the plastic transparent plate has a flat surface. In another variation of each of the above embodiments, the second substrate is a plastic transparent plate having a flat surface. In other variations, the first substrate may also be a metal plate, and one of the metal plates is light reflective. In other variations, the second substrate has a pattern, which is a text, a quotient, a pattern, or other non-meaningful pattern. In other variations, the second substrate has a pattern and the pattern is a geometric figure or line. In other variations, the opaque layer is an opaque gel, tape, dyed coating, coating or print. In other variations, the light sources are spaced around the sides of the first substrate, respectively. In other variations, the light sources are located at diagonal positions on opposite sides of the first substrate. In another embodiment of the present invention, the light emitting module includes a substrate and a plurality of light sources. A three-dimensional pattern is projected on one surface of the substrate. The light sources are respectively located on opposite sides of the first substrate, and the light sources directly project light toward each side wall of the three-dimensional pattern facing each other, thereby displaying the light-emitting contour of the three-dimensional pattern by light reflection. Thus, the present invention provides a means of displaying an illumination profile for displaying a pattern for clear viewing of a particular pattern, such as a logo (l〇g〇). BRIEF DESCRIPTION OF THE DRAWINGS The spirit of the present invention will be clearly described in the following description and the detailed description of the embodiments of the present invention, which can be modified and modified by the teachings of the present invention, The spirit and scope of the invention are not departed. The light emitting module of the present invention comprises a substrate and a plurality of light sources. The light sources are respectively located on opposite sides of the substrate, and a top surface of the substrate is provided with a convex three-dimensional pattern, so that the light source is directly used to project light to all the sidewalls of the three-dimensional pattern to present the light on the substrate by light reflection. The luminous profile of the three-dimensional pattern. In this way, the lighting module can provide a new type of lighting profile. Please refer to Figure 1 and Figure 2. FIG. 1 is a top plan view and a light distribution diagram of a light source L according to an embodiment of the present invention. Fig. 2 is a side view showing the side view of Fig. 1 and a distribution of light L. The light emitting module 100 includes a first substrate 200, one or more second substrates 300, and a plurality of light sources 500. Specifically, the first substrate 200 has a plate shape, and has a first top surface 210 and a first first bottom surface 220 opposite to each other, and a plurality of side edges 230 connecting the first top surface 210 and the 201250642 one bottom surface 220. The second substrate 300 is a plate body having a second top surface 310 and a second bottom surface 320 opposite to each other, and a plurality of side walls 330 connecting the second top surface 310 and the second bottom surface 320. The two substrates 300 are stacked on the first substrate 200 and covered by the second bottom surface 320 of the first substrate 200 . The second substrate 300 is collectively or separately arranged in a three-dimensional pattern on the first substrate 200. Such sidewalls 330 are used to describe the contour lines of the pattern(s). The pattern(s) are composed, for example, of a character, a logo, a pattern, or other meaningless figure, and the like, and the above pattern may be composed of, for example, a geometric figure or a line. In addition, in one of the alternatives of this embodiment, the light-emitting module 1 can further include an opaque layer 400. The opaque layer 400 is opaque and is disposed on all of the first top surface 210 of the first substrate 200 except for the second substrate 300. As such, the total area of the second bottom surface 320 of the second substrate 300 is smaller than the area of the first top surface 210 of the first substrate 200. The second substrate 300 completely covers all regions of the first top surface 210 of the first substrate 200, collectively referred to as "first region", and the opaque layer 400 completely covers all regions of the first top surface 210 of the first substrate 200. region". The opaque layer 400 can be, for example, an opaque gel, tape, dyed coating, plating or print, and the like. The light source 500, such as the LED light emitting elements 520' disposed on the flexible circuit board 51 (FPC), is located at least on opposite sides 230 of the first substrate 2, respectively. Therefore, the light sources 5 投射 can directly and intensively project the light 1 to all the sidewalls 330 of the second substrate 300, that is, the light L of the light sources 500 directly projects the light directly through the air to the outside of the second substrate 300. Second base 201250642 All side walls 330 of the board 300. Thus, when all the side walls 330 of the second substrate 300 are projected by the light of the light sources 5, the light L of the light sources 500 can be reflected by all the side walls 330 of the second substrate 300, and partially The two substrates 300 emit light in a direction away from the first substrate 200, thereby effectively presenting the illumination profile C of the second substrate .300 (as shown in FIG. 5) on the first substrate 200. Specifically, the light source 500 of each side 230 of the first substrate 200 can sufficiently project the light L to the side wall 330 ′ of the same side of the second substrate 300 such that all the sidewalls 330 of the second substrate 300 are The light source L of the second substrate 300 can also reflect the light L to the sidewall 330 of the other second substrate 300 to reinforce the second substrate 300. Illumination profile C. In other variations of the embodiment, the light source 500 may also be located on each side 230 of the first substrate 200 to circumferentially surround the sidewall profile of the second substrate 300. Alternatively, the light source 500 may also be used. They are respectively located on opposite sides 231 of the first substrate 200 and located just at the position of one of the imaginary diagonals A on the first substrate 200. In addition, the height of the LED light emitting element 520 may be greater than the height of the first substrate 200 after consideration. In other variations of this embodiment, the first substrate 200 is light transmissive, such as a transparent plastic plate. Preferably, however, the invention is not limited thereto, and all surfaces of the transparent plastic sheet are not subjected to optical microstructure treatment, so that the transparent plastic sheet maintains its flat surface only after molding, and does not have an optical microstructure. Therefore, the light L of the light source 500 enters the transparent plastic plate, and is not easily outputted from the first top surface 210 of the first substrate 200. 201250642 In addition, when the first substrate 200 is a transparent plastic plate, the light emitting module 100 further includes a reflective plate 600. The reflective plate 600 is located on a side of the first substrate 200 opposite to the second substrate 300 to reflect the remaining light L to the sidewall 330 of the second substrate 300 via the first substrate 200; or the first substrate 200 may also have no light guiding property, for example As a metal plate, the first top surface 210 can help reflect the light L to the sidewall 330 of the second substrate 300. The second substrate 300 has light guiding property, for example, a transparent plastic plate. Preferably, all surfaces of the transparent plastic plate are not subjected to optical microstructure processing, so that the transparent plastic plate is only formed after molding. Maintaining the status quo of its flat surface does not have an optical microstructure. Therefore, the light L of the light source 500 enters the transparent plastic plate, and is not easily outputted from the first top surface 210 of the first substrate 200. In addition, all the sidewalls 330 of the second substrate 300 may also be light reflective, for example, a smooth surface. Any surface that is suitable for reflection, such as a mirror, white or silver surface, to enhance the ability to reflect light L. Alternatively, the second substrate 300 is not light-conductive, such as a metal plate (for example, copper, aluminum plate, etc.), and all the sidewalls 330 of the second substrate 300 are light-reflective, for example, a smooth surface, a mirror surface, Any surface suitable for reflection, such as a white or silver surface, to enhance the ability to reflect light L. In addition, the first substrate 200 and the second substrate 300 may be combined by an adhesive layer or 'the first substrate 2 and the second substrate 300 may also be provided by an integral molding process' such that the second substrate 3 is convex. A three-dimensional pattern on one side of the first substrate 200.

Please refer to FIG. 3 and FIG. 4 . FIG. 3 is a plan view and a light distribution diagram of another embodiment of the light-emitting module 101 of the present invention, and FIG. 4 is a side view and light distribution of FIG. schematic diagram. The light emitting module 101 includes one or more first substrates 201, one or more second substrates 301, and a plurality of light sources 500. The second substrate 301 is stacked on the first substrate 201.

As a result, the first substrate 201 and the second substrate 301 have the same pattern outline, and together they form a three-dimensional pattern. Therefore, the second substrate 301 in the top view shields the first substrate 201. The three-dimensional pattern is composed of, for example, a character, a trademark, a pattern, or other meaningless figure or the like; in addition, the stereo pattern may be composed of, for example, a geometric figure or a line. The light source 500 (same as above) is located at least opposite to the outer side of the first substrate 201 and the second substrate 301, respectively. Therefore, the light sources 500 can directly and collectively project the light L to all the sidewalls 330 of the second substrate 301, that is, the light L of the light sources 500 directly projects the light L to the second substrate 301 only outside the second substrate 301. All of the side walls 330, such that when all of the side walls 330 of the second substrate 3〇1 are projected by the light sources of the light sources 500, the light L of the light 201250642 source 500 can be reflected by all the side walls 330 of the second substrate 301 Thereafter, the light may be partially emitted toward the second substrate 301 away from the first substrate 201, thereby effectively exhibiting the light-emitting profile C of the three-dimensional pattern (as shown in FIG. 5). In other variations of the embodiment of the light source 500, the light source 500 may also be located on opposite sides of the first substrate 201, and located just above the imaginary diagonal A on the first substrate 201 (as shown). Or, the light sources may be respectively located on each side of the first substrate to surround the three-dimensional pattern (not shown) at intervals. In addition, the height of the light source 500 may be greater than the height of the first substrate 201 (as shown) after consideration. In other variations of this embodiment, the first substrate and the second substrate are light-conducting, such as a transparent plastic plate (the material of which is the same as above). Preferably, however, the invention is not limited thereto, and all surfaces of the transparent plastic sheet are not subjected to optical microstructure treatment, so that the transparent plastic sheet maintains its flat surface only after molding, and does not have an optical microstructure. Therefore, the light of the light sources enters the transparent plastic plate, and is not easily outputted from the light emitting surface of the first substrate. Furthermore, as described in the first embodiment and the second embodiment, in another embodiment, when the first substrate is a transparent plastic plate, the light-emitting module also includes a reflector. The reflector is located on a side of the first substrate opposite to the second substrate to reflect the remaining light to the sidewall of the second substrate via the first substrate; or the first substrate may also have no light guiding property, such as a metal plate. In addition, all of the side walls of the second substrate may also be light reflective, such as a smooth surface, a mirror surface, a white or silver surface, or any other surface suitable for reflection to enhance the ability to reflect light. Alternatively, the second substrate(s) are not light-conducting, for example, a metal plate (for example, copper, aluminum plate, etc.), and all sidewalls of the second 10 201250642 substrate are light reflective, such as smooth surface, mirror surface, white or Any surface suitable for reflection, such as a silver surface, to enhance the ability to reflect light L. In this other embodiment, the first substrate and the second substrate may be bonded by an adhesive layer, or the first substrate and the second substrate may also be provided by an integral molding process. Referring to Figure 5, Figure 5 is a schematic illustration of the operation of apparatus 700 of the present invention. The present invention further provides an apparatus 700. The device 700 includes a housing 710 and a light emitting module 100 as described above. The outer casing 710 has an opening 711. The outer casing 710 covers the first substrate 200 and the light sources 500, so that the second substrate 300 can be completely exposed outside the opening 711, thereby exposing the light-emitting profile C of the second substrate 300. The device limited to the present invention is not intentionally limited to a certain field, and may be, for example, a portable electronic device, a household appliance device, a decorative wall (door), or the like. The portable electronic device is, for example, one of a notebook computer, a mobile phone, a video camera, a game machine, and a language translation machine. The household appliance device is, for example, a television, an audio, a video recorder, a dehumidifier, a lamp or a home phone, and the like. The present invention is not limited to the embodiments of the present invention, and various modifications and refinements may be made without departing from the spirit and scope of the present invention. This is subject to the definition of the scope of the patent application.
