Before working description of the present embodiment, for convenience of understanding of the present embodiment by an inspector, the principles of direct light, pinhole imaging and diffuse reflection will be specifically described: the light direct incidence principle is the most important imaging principle of the embodiment, under the condition that no external object is interfered, light is rebroadcast along a straight line, which is an important physical characteristic of light, and the straight light column and the sun light are all used for illustrating the point, so that when the hollowed pattern 7 is bigger, the light direct incidence of the light-emitting lamp 4 passes through the hollowed pattern 7 and directly projects the hollowed pattern 7 on the display cover 5, and other light is blocked by the shielding plate 6 without the hollowed pattern 7; aperture imaging refers to the process of shielding a plate with apertures between a wall and an object, and an inverted real image of the object is formed on the wall. Experimental examples: a candle is placed on the spot and is placed near the plate with the small holes. Taking a piece of white paper and placing the white paper on the other side of the small hole. Thus you see an inverted candle flame on white paper. We call it an image of a candle; diffuse reflection is a phenomenon in which light projected on a rough surface is reflected in various directions. When a parallel incident beam of light strikes a rough surface, the surface reflects the light in all directions, so that the incident beams are parallel to each other, and the reflected light is irregularly reflected in different directions due to the non-uniform normal directions of each point, and the reflection is called diffuse reflection or diffusion.
In actual operation of this embodiment, when there are four light-emitting lamps 4 and only one hollow pattern 7 is larger, the light of the four light-emitting lamps 4 respectively passes through the hollow pattern 7 and directly projects the hollow pattern 7 on the display cover 5, so that four brighter outline patterns 11 are displayed on the display cover 5, at the same time, the four brighter outline patterns 11 on the display cover 5 are reflected on the shielding plate 6 on the inner surface of the display cover 5, the outline patterns 11 reflected on the shielding plate 6 are reflected again on the display cover 5, because the brightness of the light reflected on the display cover 5 for the second time is weakened, and the light passes through the hollow pattern 7 again through the space between the light-emitting lamps 4 and the shielding plate 6 after being diffusely reflected for the second time in the interior thereof and is projected on the display cover 5, at this time, the light showing the outline patterns 11 is also weaker, the projection on the display housing 5 thus presents a darker image and the contour pattern 11 may be diffusely reflected between the inner surface of the display housing 5 and the shielding plate 6 a plurality of darker contour patterns 11 are presented on the display housing 5, so that when the user's eyes move at different angles to view the display housing 5, the contour pattern 11 is brightest when the light-emitting lamp 4, the hollowed-out pattern 7 and the human eyes are in a straight line, the other three contour patterns 11 are not in a straight line range with the human eyes because the contour pattern 11 is relatively darker, so that when the user's eyes are moving, the display housing 5 is observed to present a bright and dark varying contour pattern 11, wherein the bright contour pattern 11 is formed by the light, the dark contour pattern 11 is formed by the light oblique or diffuse reflection, and no straight line is formed with the human eyes after the light direct imaging, the outline pattern 11 will also be darker (as shown in fig. 4); and when the holes of the hollowed-out patterns 7 are smaller, the circuit board 2 is provided with a plurality of luminous lamps 4 with different positions, the luminous lamps 4 are equivalent to candles lighted in the small hole imaging, then the light of the luminous lamps 4 passes through the single hollowed-out patterns 7 on the shielding plate 6 and projects the outline of the hollowed-out patterns 7 on the display cover 5, the hollowed-out patterns 7 on the shielding plate 6 are equivalent to a plate with small holes in the small hole imaging, the display cover 5 is equivalent to white paper in the small hole imaging, so that a plurality of brighter outline patterns 11 are firstly presented on the outer surface of the display cover 5, simultaneously the display cover 5 presents a plurality of brighter outline patterns 11 which can be diffusely reflected on the shielding plate 6, the plurality of brighter outline patterns 11 reflected on the shielding plate 6 are diffusely reflected on the display cover 5 again, since the brightness of the light rays secondarily diffused and reflected onto the display cover 5 is weakened, a plurality of darker outline patterns 11 are displayed on the display cover 5, so that when the eyes of a person move at different angles to watch the display cover 5, the light-emitting lamp 4, the hollowed-out pattern 7 and the eyes of the person are in a straight line, the light rays are directly irradiated, the outline pattern 11 closest to the eyes of the person is brightest, the outline pattern 11 which is not in the direct light irradiation range of the light-emitting lamp 4 is darker, and meanwhile, a plurality of lighter and darker inter-outline patterns 11 are displayed on the display cover 5, the lighter outline patterns 11 are formed by imaging small holes, and the darker outline patterns 11 are formed by diffused reflection (as shown in fig. 4); when the light sources of the light-emitting lamps 4 are arranged on the circuit board 2 and the hollowed-out patterns 7 are arranged on the shielding plate 6, more outline patterns 11 with bright and dark phases and distinct layers are simultaneously displayed on the display cover 5 along with the movement of eyes of a person. Therefore, the embodiment not only can illuminate and decorate, but also can have ornamental value, effectively increases the functionality of the display cover, and ensures that the whole hierarchy of the patterns presented on the display cover 5 is clear, the visual effect is also plump and three-dimensional, the richness and the hierarchy of the imaging of the external image of the display cover 5 are effectively increased, the grade of the product is greatly improved, and the interest and the technological sense of the use of a user are also increased.
