Description
Technical Field
[0001] The utility model relates to a projection decoration, in particular to a projection decoration which produces a decorative effect by arranging a light-emitting component and a light-shielding cover in a shell of the decoration, wherein the light-emitting component projects light through the light-shielding cover and projects it onto the shell, so that the shell emits light and presents a projection pattern. Background Art
[0002] As people's living standards improve, they pay more and more attention to the festive atmosphere, and will place decorations to enhance the environment and add beauty.
[0003] Among them, there is a kind of luminous decoration which makes the decoration emit light by installing a luminous component inside the decoration. In combination with the shape of the decoration itself, the luminous decoration has a higher decorative value than general decorations.
[0004] However, whether the light-emitting component is turned on or off, the visual effect produced by the light-emitting decoration is determined by the shape of the decoration itself. That is to say, the visual effect produced by the light-emitting decoration is not much different when it is lit or not, so there is a lack of surprise, which makes the decorativeness of the light-emitting decoration still relatively insufficient.
[0005] Another type of luminous decoration is to install a film with a pattern inside the decoration, and project light onto the film through a luminous component to form a projection pattern on the surface of the decoration. However, the edge of the projection pattern is often blurred, so the decorative effect is still relatively insufficient and there is room for improvement. Utility Model Content

[0007] The technical solution proposed by the utility model is to provide a projection decoration, which includes:
[0008] A housing, the interior of which is hollow and light-permeable;
[0009] A light-emitting component is disposed inside the housing and comprises a substrate and a plurality of light-emitting units. The plurality of light-emitting units are disposed on the substrate and are controlled to emit light;
[0010] a light shield, which is disposed on the substrate and includes a light shielding body and at least one partition wall, the light shielding body is hollow, a plurality of hollow pattern portions are formed on the light shielding body, the at least one partition wall is disposed in the light shielding body and is located between every two adjacent hollow pattern portions, the substrate of the light emitting component is combined with the light shielding body, and the plurality of light emitting units correspond to the plurality of hollow pattern portions respectively; and
[0011] A controller is electrically connected to the light-emitting component and can control each of the light-emitting units to turn on or off, so that each of the light-emitting units projects light toward the corresponding hollow pattern portion, and the light is projected onto the housing through the hollow pattern portion, so that the projection pattern of the corresponding hollow pattern portion appears on the housing, and the controller can control a part of the light-emitting units among the plurality of light-emitting units to turn on and another part of the light-emitting units to turn off.
[0012] Preferably, as in the aforementioned projection decoration, the light-shielding body has a combining opening, the substrate of the light-emitting component is disposed in the combining opening of the light-shielding body, the plurality of light-emitting units extend into the light-shielding body, and two adjacent light-emitting units are separated by the at least one partition wall.
[0013] Preferably, as in the aforementioned projection decoration, the controller has a sound module, the sound module can emit sound, and the sound module can emit sound in conjunction with the plurality of light-emitting units being turned on or off.
[0014] Preferably, as in the aforementioned projection decoration, a part of the plurality of light-emitting units projects light toward the corresponding hollow pattern portion, so that when the light passes through the hollow pattern portion and is projected onto the housing, the projection patterns on the housing partially overlap with each other.
[0015] Preferably, as the aforementioned projection decoration, the shell includes a front shell and a rear shell, the front shell is combined with the rear shell, the light-emitting component and the shade are located in the shell, the substrate of the light-emitting component is arranged on the rear shell, and the plurality of light-emitting units project light toward the front shell.
[0016] Preferably, as in the aforementioned projection decoration, the shell is made of a flexible material, and the projection decoration comprises a blower, which is connected to the shell and inflates air into the shell to make the shell three-dimensional.
[0017] Preferably, as in the aforementioned projection decoration, at least one pattern portion is disposed on the outer side of the shell.
[0018] Preferably, as in the aforementioned projection decoration, a portion of the plurality of light-emitting units projects light toward the corresponding hollow pattern portion, so that when the light passes through the hollow pattern portion and is projected onto the housing, a portion of the projection pattern on the housing overlaps with the at least one pattern portion.
[0019] The beneficial effects that can be achieved by the utility model are as follows: the projection decoration of the utility model is to install the light-emitting component and the light-shielding cover inside the shell, and the controller controls the several light-emitting units of the light-emitting component to project light, so that the light passes through the hollow pattern part of the light-shielding cover and is projected onto the shell, so that the shell emits light and presents a projection pattern, so that the projection decoration can produce a decorative effect. Among them, since the several hollow pattern parts are separated by the at least one partition wall, the light emitted by the several light-emitting units will not interfere with each other when projected onto the several hollow pattern parts, and since the overall projection pattern is divided into several projection patterns respectively projected by the several hollow pattern parts and the several light-emitting units, the area of each projection pattern is small and the light is more concentrated, so that the edge blur of the projection pattern can be avoided, so that a clear projection pattern can be presented on the shell.
[0020] Moreover, when the controller controls the several light-emitting units to be turned off, the visual effect presented by the projection decoration is only the appearance of the shell, and when the controller controls the several light-emitting units to be turned on, the projection patterns of the hollow pattern parts corresponding to the several light-emitting units will appear on the shell. Therefore, the visual effects presented by the projection decoration when it is illuminated or not are very different, which can create a sense of surprise and provide higher decorativeness and interest.
[0021] In addition, the controller can control a part of the light-emitting units to turn on and another part of the light-emitting units to turn off, so that the projection patterns of the hollow pattern parts corresponding to different light-emitting units are presented on the shell, and the several hollow pattern parts can have different patterns, so different projection patterns will be presented on the shell, so that the shell presents an animation-like pattern effect, which can further enhance the sense of surprise, decorativeness and interest.

[0061] The following is a detailed description of the technical means used by the present invention to achieve the intended purpose of the present invention with reference to the drawings and preferred embodiments of the present invention.
[0062] See also Figure 1 , Figure 2 , Fig.13 and Fig. 20 , which are several preferred embodiments of the projection decoration of the present invention, include a housing 10a, 10b, 10c, a light emitting component 20, a light shield 30 and a controller 40.
[0063] like Figure 2 , Fig.13 and Fig. 20 As shown, the shells 10a, 10b, 10c are hollow inside and can transmit light.
[0064] like Figure 2 , Figure 3 , Fig.13 and Fig. 20 As shown, the light emitting assembly 20 is disposed inside the housing 10a, 10b, 10c and includes a substrate 21 and a plurality of light emitting units 22. The plurality of light emitting units 22 are disposed on the substrate 21 and are controlled to emit light.
[0065] like Figures 2 to 5 , Figures 13 to 15 , Fig.21 and Fig. 22 As shown, the light shield 30 is disposed on the substrate 21 and includes a light shielding body 31a, 31b, 31c and at least one partition wall 32. The light shielding body 31a, 31b, 31c is hollow, and a plurality of hollow pattern portions 311a~311j are formed on the light shielding body 31a, 31b, 31c. The at least one partition wall 32 is disposed in the light shielding body 31a, 31b, 31c and is located between every two adjacent hollow pattern portions 311a~311j. The substrate 21 of the light emitting component 20 is combined with the light shielding body 31a, 31b, 31c, and the plurality of light emitting units 22 respectively correspond to the plurality of hollow pattern portions 311a~311j. The plurality of hollow pattern portions 311a~311j are hollow holes with a preset shape formed on the light shielding body 31a, 31b, 31c.
[0066] like Fig.11 and Fig.12As shown, the controller 40 is electrically connected to the light-emitting component 20, and can control each of the light-emitting units 22 to turn on or off, so that each of the light-emitting units 22 projects light toward the corresponding hollow pattern portion 311a~311j, and the light is projected to the housing 10a, 10b, 10c through the hollow pattern portion 311a~311j, so that the projection patterns 60a~60i of the corresponding hollow pattern portion 311a~311j are presented on the housing 10a, 10b, 10c, and the controller 40 can respectively control a part of the light-emitting units 22 to turn on and another part of the light-emitting units 22 to turn off.
[0067] like Figures 7 to 9 , Fig.11 , Fig.12 and Figures 16 to 19 As shown, the projection ornament of the utility model is arranged by installing the light emitting assembly 20 and the light shield 30 inside the housing 10a, 10b, 10c, and the controller 40 controls the plurality of light emitting units 22 of the light emitting assembly 20 to project light, so that the light passes through the hollow pattern portions 311a~311j of the light shield 30 and is projected onto the housing 10a, 10b, 10c, so that the housing 10a, 10b, 10c emits light and presents projection patterns 60a~60i, so that the projection ornament can produce a decorative effect.
[0068] In addition, if Fig.11 As shown, the housing 10a, 10b of the projection decoration of the utility model can be installed on a ground plug 70 and placed on the ground for use; Fig.12 As shown, multiple projection decorations of the present invention can also be connected by cables and hung for use, such as hanging on eaves or fences, and multiple projection decorations can be connected and controlled to light up at the same time by the same controller 40 to better create an atmosphere and save the cost of the controller 40 at the same time.
[0069] Furthermore, if Figure 6 As shown, since the plurality of hollow pattern portions 311a-311j are separated by the at least one partition wall 32, the light emitted by the plurality of light emitting units 22 will not interfere with each other when projected onto the plurality of hollow pattern portions 311a-311j, so that clear projection patterns 60a-60i can be presented on the housing 10a, 10b, 10c. Preferably, as Figure 3 and Fig. 22As shown, the shading body 31a, 31b, 31c has a combining opening 312, the substrate 21 of the light emitting component 20 is arranged in the combining opening 312 of the shading body 31a, 31b, 31c, the several light emitting units 22 extend into the shading body 31a, 31b, 31c, and two adjacent light emitting units 22 are separated by the at least one partition wall 32, thereby ensuring that the light emitted by the several light emitting units 22 is separated, so that the projection patterns 60a~60i are clearer, and since the overall projection pattern is divided into several projection patterns 60a~60i respectively projected by the several hollow pattern portions 311a~311j and the several light emitting units 22, each projection pattern 60a~60i has a smaller area and the light is more concentrated, thereby avoiding blurring of the edges of the overall projection pattern, making the overall projection pattern clearer.
[0070] Moreover, if Figure 7 , Fig.16 and Fig. 20 As shown in FIG. 1 , when the controller 40 controls the plurality of light emitting units 22 to be turned off, the visual effect presented by the projection decoration is only the appearance of the housing 10a, 10b, 10c. Figure 8 , Fig. 9 and Figures 17 to 19 As shown, when the controller 40 controls the several light-emitting units 22 to turn on, projection patterns 60a~60i of the hollow pattern parts 311a~311j corresponding to the several light-emitting units 22 will appear on the shell 10a, 10b, 10c. Therefore, the visual effect presented by the projection decoration when it is illuminated or not is very different, which can create a sense of surprise and provide higher decorativeness and interest.
[0071] Preferably, the controller 40 has a sound module that can emit sound, and the sound module can emit sound in conjunction with the opening or closing of the plurality of light-emitting units 22. By the controller 40 simultaneously controlling the opening or closing of the plurality of light-emitting units 22 of the light-emitting assembly 20 and controlling the sound module to emit sound, the projection decoration of the utility model can better create a sense of atmosphere and further enhance the fun.
[0072] In addition, if Figure 8 , Fig. 9 and Figures 17 to 19As shown, the controller 40 can control a part of the light emitting units 22 to be turned on and another part of the light emitting units 22 to be turned off, so that the projection patterns 60a~60i of the hollow pattern parts 311a~311j corresponding to different light emitting units 22 are presented on the shell 10a, 10b, 10c, and the several hollow pattern parts 311a~311j can have different patterns. Therefore, different projection patterns 60a~60i will be presented on the shell 10a, 10b, 10c, so that the shell 10a, 10b, 10c presents an animation-like pattern effect, which can further enhance the sense of surprise, decorativeness and fun.
[0073] The controller 40 can be pre-set to turn on or off which light emitting units 22 are to be turned on or off. For example, in the first preferred embodiment of the present invention, Figure 8 As shown, the controller 40 first controls the light emitting unit 22 corresponding to the hollow pattern portion 311a to turn on and the light emitting unit 22 corresponding to the hollow pattern portion 311b to turn off, so the projection pattern 60a presented on the housing 10a corresponds to the hollow pattern portion 311a, and Fig. 9 As shown, the controller 40 can also control the two light-emitting units 22 corresponding to the hollow pattern portion 311a and the hollow pattern portion 311b to be turned on at the same time, that is, a part of the light-emitting units 22 cast light toward the corresponding hollow pattern portions 311a, 311b, so that when the light passes through the hollow pattern portions 311a, 311b and is projected onto the housing 10a, the projection patterns 60a, 60b on the housing 10a partially overlap with each other, and the projection patterns 60a, 60b corresponding to the hollow pattern portions 311a, 311b will be simultaneously presented on the housing 10a.
[0074] Similarly, in the second preferred embodiment of the present invention, Figures 15 to 17 As shown, the controller 40 first controls the light emitting units 22 corresponding to the hollow pattern parts 311c, 311d, 311e to turn on and the light emitting units 22 corresponding to the hollow pattern parts 311f, 311g to turn off, and the projection patterns 60c, 60d, 60e presented on the housing 10b correspond to the hollow pattern parts 311c, 311d, 311e. Fig.18As shown, the controller 40 can control the light-emitting units 22 corresponding to the hollow pattern parts 311f, 311g to turn on, and the projection patterns 60c~60g of the corresponding hollow pattern parts 311c~311g will be simultaneously presented on the shell 10b; or the controller 40 can control the light-emitting units 22 corresponding to the hollow pattern parts 311c, 311f, 311g to turn on and the light-emitting units 22 corresponding to the hollow pattern parts 311d, 311e to turn off, and the projection patterns 60c, 60f, 60g of the corresponding hollow pattern parts 311c, 311f, 311g will be presented on the shell 10b, and the projection patterns 60c, 60f, 60g will not overlap with each other.
[0075] In addition, in the third preferred embodiment of the present utility model, Fig.19 As shown, the controller 40 controls the light emitting units 22 corresponding to the hollow pattern parts 311h, 311i to turn on, and controls the light emitting units 22 corresponding to the hollow pattern parts 311j to turn off, so that the projection patterns 60h, 60i corresponding to the hollow pattern parts 311h, 311i are presented on the housing 10c.
[0076] Furthermore, if Figure 2 and Fig.13 As shown in the first and second preferred embodiments of the present invention, the housing 10a, 10b is made of a hard material and includes a front housing 11 and a rear housing 12, the front housing 11 and the rear housing 12 are combined, the light emitting assembly 20 and the light shield 30 are located in the housing 10a, 10b, the substrate 21 of the light emitting assembly 20 is disposed on the rear housing 12, and the plurality of light emitting units 22 project light toward the front housing 11; and as shown in FIG. Fig.19 and Fig. 20 As shown, in the third preferred embodiment of the present invention, the housing 10c is made of a flexible material, and the projection decoration comprises a blower 50, which is connected to the housing 10c and inflates the housing 10c to make the housing 10c three-dimensional. Regardless of whether the housings 10a, 10b, and 10c are made of a flexible material or a hard material, the projection decoration of the present invention can provide a high degree of decorativeness and interest, so consumers can choose different embodiments of the present invention according to their own decorative needs.
[0077] In addition, if Fig.10As shown, at least one pattern portion 13 is provided on the outer side of the housing 10a, 10b, 10c. The at least one pattern portion 13 is provided on the outer side of the housing 10a, 10b, 10c by printing or pasting, or is formed integrally with the housing 10a, 10b, 10c. By providing the at least one pattern portion 13 on the outer side of the housing 10a, 10b, 10c, the decorativeness of the projection decoration can be increased by the at least one pattern portion 13. Furthermore, when a portion of the light-emitting units 22 casts light toward the corresponding hollow pattern portions 311a~311j, so that when the light passes through the hollow pattern portions 311a~311j and is projected onto the housing 10a, 10b, 10c, a portion of the projection patterns 60a~60i on the housing 10a, 10b, 10c overlaps with the at least one pattern portion 13. Therefore, the at least one pattern portion 13 can also be coordinated with the projection patterns 60a~60i of the corresponding hollow pattern portions 311a~311j on the housing 10a, 10b, 10c after the light-emitting units 22 are turned on, thereby increasing the interest of the decoration.
[0078] In summary, the projection ornament of the present invention installs the light-emitting component 20 and the light-shielding cover 30 inside the shell 10a, 10b, 10c, and the controller 40 controls the several light-emitting units 22 of the light-emitting component 20 to project light, so that the light passes through the hollow pattern parts 311a~311j of the light-shielding cover 30 and is projected onto the shell 10a, 10b, 10c, so that the shell 10a, 10b, 10c emits light and presents projection patterns 60a~60i, and the controller 40 can control a part of the light-emitting units 22 to be turned on and another part of the light-emitting units 22 to be turned off, so that the shell 10a, 10b, 10c presents the projection patterns 60a~60i of the hollow pattern parts 311a~311j corresponding to different light-emitting units 22, which can further enhance the sense of surprise, decorativeness and fun of the projection ornament of the present invention.
