[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] refer to Figure 1 , Figure 1 A schematic diagram of the structure of a projection welcome lamp provided by the embodiment of the utility model, referring to Figure 2 , Figure 2 A schematic diagram of another projection welcome lamp provided by the embodiment of the utility model, referring to Figure 3 , Figure 3 A partial structural diagram of a projection welcome lamp provided by an embodiment of the utility model, referring to Figure 4 , Figure 4 A schematic diagram of the structure of a control component provided by an embodiment of the utility model. A projection welcome lamp provided by an embodiment of the utility model comprises: a light source 11, a film 12, at least one projection lens 13 and a control component 14.

[0041] The light source 11 includes a plurality of light-emitting elements, a plurality of images corresponding to the plurality of light-emitting elements are arranged on the film sheet 12 , and the film sheet 12 is located between the projection lens 13 and the light source 11 .

[0042] The light source 11 is used to emit light and illuminate the image on the film 12 .

[0043] The control component 14 is used to control the plurality of light emitting elements to be in a lighting state or an off state, and the projection lens 13 is used to project a target image onto a target object, wherein the target image is an image corresponding to the light emitting elements in the lighting state.

[0044] Specifically, in the embodiment of the utility model, the projection welcome lamp controls the light-emitting state of multiple light-emitting elements through the control component 14 to realize the switching of the projection image. By reasonably partitioning the film 12 to set the image, a more delicate and smooth dynamic projection effect can be achieved. In other words, the technical solution can remove the unstable influence of the motor and use the control logic of multiple light-emitting elements to achieve a stable and smooth dynamic effect. For example, the light-emitting elements are controlled by the control component 14 to switch the pattern. Compared with other existing projection technologies, the cost is lower, and the projection area and projection image effect are significantly improved.

[0045] It should be noted that in order to achieve the best projection display effect, the control component 14 needs to drive the light source to coordinate in real time to realize light source actions such as breathing, strobing, and bright and dark, thereby achieving a dynamic effect with no ghosting, no abnormal flickering, and high brightness.

[0046] It should be noted that the number of projection lenses 13 can be one or more. When the number of projection lenses 13 is more than one, the number of projection lenses 13 is the same as the number of light-emitting elements. The projection lenses 13 and the light-emitting elements are arranged in a one-to-one correspondence to realize multiple independent optical paths. In the embodiment of the utility model, eight projection lenses 13 are taken as an example for description, that is, eight projection optical paths are taken as an example for description in the embodiment of the utility model.

[0047] Optionally, in another embodiment of the present invention, refer to Figure 5 , Figure 5 A schematic diagram of a packaging shell provided by an embodiment of the utility model, wherein the projection welcome lamp further comprises:

[0048] A packaging shell, in which all components of the projection welcome lamp are integrated and packaged.

[0049] Specifically, in the embodiment of the present utility model, Figure 5 As shown, the encapsulation shell can be composed of a mask 19 and a shell 20. After the mask 19 and the shell 20 are connected, a encapsulation shell can be formed, which can improve the integration and structural stability of the projection welcome lamp.

[0050] It should be noted that the mask area facing the projection lens 13 is a transparent area, which ensures that the projection lens 13 can normally project the image onto the target object, for example, ensures that the projection lens 13 can normally project the image onto the ground.

[0051] Optionally, in another embodiment of the present invention, refer to Figure 6 , Figure 6 This is a partial structural schematic diagram of another projection welcome light provided by an embodiment of the utility model. The projection welcome light further includes: a plurality of lens assemblies 15.

[0052] The plurality of lens assemblies 15 are located between the film 12 and the light source 11 , and the plurality of lens assemblies 15 correspond one-to-one to the plurality of light-emitting elements.

[0053] Specifically, the lens assembly 15 exemplified in the embodiment of the utility model is a collimating lens, and the light emitting surface of the collimating lens is arranged in a one-to-one correspondence with the light incident surface of the projection lens 13, wherein the lens assembly 15 mainly plays the role of focusing light. Taking the collimating lens as an example for explanation, the collimating lens is arranged corresponding to the light emitting element, and the collimating lens includes a light incident surface and a light exiting surface. The light incident surface is used to receive the light emitted by the light emitting element, focusing the light into parallel light or light at a certain angle, so that the light converges, and then the light emitted through the light exiting surface of the collimating lens can be more evenly irradiated onto the image on the film 12, so as to improve the optical utilization rate, thereby improving the display effect of the final projection image of the projection welcome light.

[0054] Optionally, in another embodiment of the present invention, as Figure 6 As shown, the projection welcome lamp further includes: a circuit board 21.

[0055] The plurality of light emitting elements are disposed on the circuit board 21 , and the circuit board 21 is connected to the control component 14 .

[0056] Specifically, in the embodiment of the utility model, the light emitted by the light source 11 needs to be irradiated on the image on the film 12, so the display effect of the final projected image is inseparable from the performance of the light source 11. Based on this, in the embodiment of the utility model, multiple light-emitting elements are fixed on the circuit board 21, and then the circuit board 21 can be fixedly connected to the packaging shell. Under the condition that the control component 14 controls the light-emitting element through the circuit board 21, it can also be ensured that the position of the light-emitting element will not be offset, and then the light path emitted by the light-emitting element will not be offset, ensuring that there is enough light to irradiate the image on the film 12, so as to improve the display effect of the final projected image of the projection welcome lamp. In other words, the circuit board can also play a role in supporting the light-emitting element.

[0057] Exemplarily, the light-emitting element includes but is not limited to an LED light-emitting element, and preferably a high-brightness LED light-emitting element is used. In the embodiment of the utility model, the number of light-emitting elements and the color of the light emitted are not limited. For example, multiple light-emitting elements can be selectively selected in combination with the image on the film 12. Obviously, light-emitting elements that emit white light or light-emitting elements that emit colored light can also be selected.

[0058] Optionally, in another embodiment of the present invention, refer to Figure 7 , Figure 7 This is a partial structural diagram of another projection welcome lamp provided in an embodiment of the utility model. The projection welcome lamp further includes: a bracket 16.

[0059] The film 12 is fixed on the bracket 16 .

[0060] Specifically, in the embodiment of the utility model, by fixing the film 12 on the bracket 16, the bracket 16 can be fixedly connected to the packaging shell, which can ensure that the position of the film 12 will not shift, thereby improving the display effect of the final projection image of the projection welcome lamp.

[0061] Optionally, in another embodiment of the present invention, refer to Figure 8 , Figure 8 This is a partial structural diagram of another projection welcome lamp provided in an embodiment of the utility model. The projection welcome lamp further includes: a pressure plate 17.

[0062] The at least one projection lens 13 is fixed on the pressure plate 17 .

[0063] Specifically, in the embodiment of the utility model, the projection lens 13 is fixed on the pressure plate 17, and then the pressure plate 17 can be fixedly connected to the packaging shell, so as to ensure the stability of the projection lens 13, thereby improving the display effect of the final projection image of the projection welcome lamp.

[0064] Optionally, in another embodiment of the present invention, refer to Fig. 9 , Fig. 9 This is a partial structural diagram of another projection welcome lamp provided in an embodiment of the utility model. The projection welcome lamp further includes: a radiator 18.

[0065] The heat sink 18 is fixed to a side of the light source 11 facing away from the film 12 .

[0066] Specifically, in the embodiment of the utility model, the light-emitting element is fixed on the circuit board 21, the film 12 is fixed on the bracket 16, and the projection lens 13 is fixed on the pressure plate 17. Then, these components are combined together and fixed on the radiator 18, so as to achieve heat dissipation treatment of the device and improve the service life of the projection welcome lamp.

[0067] It should be noted that the control component 14 can also be fixed on the radiator 18 to achieve heat dissipation for the control component 14 .

[0068] It should be noted that the multiple light paths provided by the present technical solution may also include at least one background light path, that is, in addition to the light-emitting elements used for the projection function, some additional background light-emitting elements may also be set. When the projection welcome light is operating, the background light path mainly provides auxiliary lighting function, the light source is constantly on, does not require additional control, and only responds to switches and sleep wake-up protocols; the dynamic light path provides dynamic projection content, including but not limited to breathing, strobing, bright and dark and other light source actions. The complete response time must be controlled within 5ms to ensure the dynamic effect.

[0069] Or, the multiple light paths provided by the technical solution include at least two dynamic light paths. When the projection welcome light is operating, one of the dynamic light paths serves as a background light path and mainly provides auxiliary lighting and dynamic background functions. The light source is constantly on and does not require additional control. It only responds to switches and sleep wake-up protocols. Other dynamic light paths provide dynamic projection content, including but not limited to breathing, strobing, bright and dark light source actions. The complete response time must be controlled within 1ms to ensure a high-dynamic, flicker-free dynamic effect.

[0070] That is to say, the number and functions of the plurality of light emitting elements can be designed more reasonably based on actual application requirements, and are not limited in the embodiments of the present utility model.
