[0024] With the advancement of technology and the popularization of lighting products, the application of forming patterns through light is gradually increasing, and the categories are endless.

[0025] In the related art, the pattern generation module of the pattern generation device is fixed to the rotating module. During the rotation of the rotating module, the light emitted by the light source module is emitted to the pattern generation unit to display the pattern corresponding to the pattern generation unit. The type of pattern that can be generated depends on the type of the pattern generation unit, that is, there are two types of pattern generation units, which can only generate two types of patterns, which is relatively simple. In addition, the cost of the light source module is relatively high, and the limitation of pattern setting limits the richness of the product itself and cannot meet the growing market demand.

[0026] In order to improve the above-mentioned problems, the inventors have proposed a pattern generating device and equipment provided by the present application, which includes: a control module; a plurality of rotation modules, each of which is connected to the control module respectively; a plurality of light source modules, each of which corresponds to a plurality of rotation modules one by one; each light source module is connected to a corresponding rotation module, and each light source module is also connected to the control module respectively; a pattern generating module, including a plurality of pattern generating units, and the patterns on each pattern generating unit are different; the control module is used to send a plurality of dimming signals to the corresponding light source modules respectively; the control module is also used to send a plurality of angle signals to the corresponding rotation modules respectively; wherein the plurality of dimming signals correspond to the plurality of light source modules one by one; the plurality of angle signals correspond to the plurality of rotation modules one by one; each light source module is used to emit light according to the corresponding dimming signal; each rotation module is used to drive the corresponding light source module to rotate to an emission angle corresponding to the angle signal, so that the light emitted by the light source module is directed toward one of the pattern generating units; thereby, by adjusting the emission angle and emitted light of the light source module, the pattern types can be greatly enriched at a limited cost to meet market demand.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] See also Figure 1 , Figure 1 is a schematic diagram of the structure of a pattern generating device disclosed in an embodiment of the present application, such as Figure 1 As shown, the pattern generating device 100 includes: a control module 110 , a plurality of rotation modules 120 , a plurality of light source modules 130 , and a pattern generating module 140 .

[0029] Each rotation module 120 is respectively connected to the control module 110. The rotation module 120 can rotate according to the signal sent by the control module 110. The rotation module 120 can include a stepper motor, a DC motor, etc., which can be selected according to actual needs, and this application does not limit this.

[0030] The plurality of light source modules 130 correspond to the plurality of rotating modules 120 one by one, each light source module 130 is connected to the corresponding rotating module 120, and the light source module 130 can be driven by the corresponding rotating module 120, so that the angle of the light emitted by the light source module 130 can be adjusted. The light source module 130 can be a laser module, and in other embodiments, an LED (Light Emitting Diode) module can also be used, which can be selected according to actual use needs, and this application does not limit this.

[0031] Each light source module 130 is also connected to the control module 110 , and the light source module 130 can adjust the parameters of the emitted light, such as the brightness, color, dimming frequency, etc. of the emitted light, according to the signal emitted by the control module 110 .

[0032] In some embodiments, the pattern generating device 100 includes three light source modules 130 , among which one light source module 130 is used to emit red light; another light source module 130 is used to emit green light; and another light source module 130 is used to emit blue light.

[0033] The pattern generation module 140 includes a plurality of pattern generation units 141, each of which corresponds to a pattern. In the embodiment of the present application, the light source module 130 can rotate so as to selectively project light onto different pattern generation units 141, and a combination of multiple patterns can be obtained by adjusting the angle at which the light source module 130 emits light.

[0034] For example, the pattern generating module 140 may include a first pattern generating unit and a second pattern generating unit, the first pattern generating unit corresponds to a first pattern, and the second pattern generating unit corresponds to a second pattern; the multiple light source modules 130 include a first light source module and a second light source module, and three patterns of different shapes may be generated, namely, pattern 1, pattern 2, and a combination of pattern 1 + pattern 2. Furthermore, by adjusting the parameters of the emitted light of the light source module 130, the types of patterns that can be generated may be further enriched.

[0035] In the embodiment of the present application, each pattern generating unit 141 corresponds to at least one light source module 130 .

[0036] In some embodiments, each pattern generating unit 141 corresponds to one light source module 130 .

[0037] Optionally, the plurality of pattern generating units 141 correspond one to one with the plurality of light source modules 130. Figure 2As shown, the pattern generation module 140 may include a first pattern generation unit (corresponding to pattern 1), a second pattern generation unit (corresponding to pattern 2) and a third pattern generation unit (corresponding to pattern 3), and the plurality of light source modules 130 include a first light source module (corresponding to emitting red light), a second light source module (corresponding to emitting green light) and a third light source module (corresponding to emitting blue light); the first pattern generation unit is arranged correspondingly to the first light source module, and the second pattern generation unit is arranged correspondingly to the second light source module. Thus, three patterns of different shapes may be generated, including a first pattern (red pattern 1), a second pattern (green pattern 2) and a third pattern (blue pattern 3).

[0038] Optionally, each pattern generation unit 141 can correspond to any light source module 130 in the multiple light source modules 130, that is, different pattern generation units 141 can correspond to the same light source module 130. For example, the pattern generation module 140 may include a first pattern generation unit and a second pattern generation unit, and the multiple light source modules 130 include a first light source module and a second light source module. The first pattern generation unit is arranged corresponding to the first light source module, and the second pattern generation unit is also arranged corresponding to the first light source module.

[0039] In some embodiments, among the multiple pattern generating units 141, there is at least one pattern generating unit 141 corresponding to the multiple light source modules 130. For example, the pattern generating module 140 may include a first pattern generating unit and a second pattern generating unit, and the multiple light source modules 130 include a first light source module, a second light source module, and a third light source module. The first pattern generating unit may be set corresponding to the first light source module, and the second pattern generating unit may be set corresponding to the second light source module and the third light source module. It is understandable that the light source modules 130 corresponding to different pattern generating units 141 may be the same or different. For example, the first pattern generating unit may also be set corresponding to the second light source module and the third light source module. The specific setting may be based on the use requirements of the pattern, and the present application does not limit this.

[0040] For example, Figure 3 As shown, the pattern generation module 140 may include a first pattern generation unit (corresponding to pattern 1), a second pattern generation unit (corresponding to pattern 2) and a third pattern generation unit (corresponding to pattern 3), and the plurality of light source modules 130 include a first light source module (corresponding to emitting red light), a second light source module (corresponding to emitting green light) and a third light source module (corresponding to emitting blue light); wherein the second pattern generation unit is arranged corresponding to the first light source module, and the third pattern generation unit is arranged corresponding to the second light source module and the third light source module. Thus, two patterns of different shapes may be generated, including a fourth pattern (red pattern 2) and a fifth pattern (yellow pattern 3).

[0041] For example, Figure 4 As shown, the pattern generation module 140 may include a first pattern generation unit (corresponding to pattern 1), a second pattern generation unit (corresponding to pattern 2) and a third pattern generation unit (corresponding to pattern 3), and the plurality of light source modules 130 include a first light source module (corresponding to emitting red light), a second light source module (corresponding to emitting green light) and a third light source module (corresponding to emitting blue light); wherein the third pattern generation unit is arranged correspondingly to the first light source module, the second light source module and the third light source module. Thus, a sixth pattern (white pattern 3) may be generated.

[0042] In some embodiments, the pattern generating unit 141 includes: a light mixing sheet and a diffractive optical unit. The light mixing sheet is used to adjust the received light to form an adjusted light; the diffractive optical unit is used to form a light pattern according to the adjusted light and a preset pattern structure. The diffractive optical unit can use a DOE (diffractive optical element). The DOE utilizes the diffraction phenomenon of light, that is, the phenomenon that light waves bend and scatter when encountering obstacles or small holes during propagation. The incident light is modulated through the microstructure on its surface (such as gratings, relief patterns, etc.), so that the light waves bend and disperse during propagation, thereby achieving precise control of the light field.

[0043] Optionally, the light mixing sheet can adjust the direction of the received light so that the light can be directed toward the diffractive optical unit for pattern generation. It is understandable that in other embodiments, combined with actual use needs, the light mixing sheet can also adjust the brightness, contrast and other parameters of the received light, which can be adjusted according to the needs of the use scenario, and this application does not limit this.

[0044] In some embodiments, the light mixing sheet receives a light ray, and the light mixing sheet can adjust the direction of the received light ray so that the light ray can be directed toward the diffractive optical unit. In other embodiments, the light mixing sheet can receive multiple light rays at the same time. When receiving multiple light rays, the light mixing sheet can mix the multiple light rays and adjust the direction of the mixed light rays to form adjusted light rays so that the light ray can be directed toward the diffractive optical unit. By mixing the light rays, adjusted light rays with richer colors can be obtained, further enriching the types of patterns.

[0045] The control module 110 is used to determine multiple dimming signals and multiple angle signals according to the pattern setting information; the multiple dimming signals correspond to the multiple light source modules 130 one by one; the multiple angle signals correspond to the multiple rotation modules 120 one by one. The user can set the desired pattern according to the needs, for example, through the terminal device, and the terminal device forms the pattern setting information according to the user's settings. The pattern setting information may include the shape of the pattern, the color of the pattern, the brightness of the pattern, the dimming linearity, etc.

[0046] Among them, the shape of the pattern can be used to determine the pattern generation unit that needs to participate in pattern generation, for example, pattern 1 corresponds to the first pattern generation unit, pattern 2 corresponds to the second pattern generation unit, and pattern 3 corresponds to the first pattern generation unit and the second pattern generation unit; the control module 110 can determine the pattern generation unit that needs to participate in pattern generation based on the corresponding relationship between the preset pattern generation unit and the pattern.

[0047] The user may also directly select the pattern generation unit that needs to participate in pattern generation on the terminal device, for example, directly select the first pattern generation unit, the second pattern generation unit, or select the first pattern generation unit and the second pattern generation unit at the same time. The control module 110 may directly determine the pattern generation unit that needs to participate in pattern generation according to the pattern generation unit information corresponding to the pattern setting information.

[0048] The control module 110 can determine the parameters of the emitted light corresponding to each light source module 130 according to the pattern color, the brightness of the pattern, the dimming linearity, etc., such as the color, brightness and dimming frequency of the emitted light. The control module 110 can determine the parameters of the emitted light corresponding to each light source module 130 according to the correspondence between the preset light generation pattern generation unit and the pattern.

[0049] Each light source module 130 is used to receive a corresponding dimming signal and to emit light according to the dimming signal. Each rotation module 120 is also used to receive a corresponding angle signal and to drive the corresponding light source module 130 to rotate to an emission angle corresponding to the angle signal, so that the light emitted by the light source module 130 is directed toward one of the pattern generation units 141, so that the patterns on the pattern generation module 140 can be combined according to user needs, and the pattern effect can also be set by adjusting the parameters of the emitted light. In the case of a limited number of light source modules 130 and pattern generation modules 140, more pattern types can be obtained, which meets user needs while reducing costs.

[0051] The first end of the signal strengthening unit 121 is used to receive the corresponding angle signal, and the signal strengthening unit 121 is used to strengthen the angle signal to form a driving signal. The signal generated by the control module 110 cannot directly drive the signal driving unit 122, so the received angle signal needs to be strengthened.

[0052] In some implementations, the signal strengthening unit 121 may use a Darlington tube, an operational amplifier, or other device that can be used to strengthen the signal. The specific device may be selected based on actual needs, and the present application does not impose any limitation on this.

[0053] The signal driving unit 122 is connected to the second end of the signal reinforcing unit 121 , and is used to drive the corresponding light source module 130 according to the driving signal, so that the corresponding light source module 130 rotates to an emission angle corresponding to the driving signal.
