Description

Technical Field

[0001] This utility model relates to the field of projection lamps, specifically to a multifunctional lamp suitable for multiple applications. Background Technology

[0002] Starry sky projectors, as lighting fixtures that combine illumination and ambiance creation, are widely used in home decoration, children's rooms, and party settings. Current starry sky projectors only offer a single starry sky projection function. While some products have added ambient light switching capabilities, they suffer from the following shortcomings: First, their dynamic dimming intelligence is low, making it difficult to quickly switch between ordinary lighting, ambient lighting, and starry sky projection, thus hindering multi-functionality. Second, the integration of dynamic dimming is insufficient, failing to meet users' needs for multi-scene, multi-functional use. Third, the dimming structure design is unreasonable; traditional dimming methods often rely on frosted light-blocking plates to adjust brightness, making rapid switching between frosted and transparent states impossible. Fourth, the projection method is limited, making it difficult to switch the electric field of the projection on a near-field and far-field projection screen. In short, current projector technology suffers from low intelligent control; to date, no fixtures utilize electronically controlled dimming films that can switch between light scattering and transparent states, leaving room for improvement in user convenience. Utility Model Content

[0003] The purpose of this invention is to provide a new type of lamp that combines an electronically controlled dimming film, which solves the problems of existing projection lamps having single functions and lacking intelligent control, and realizes the integrated presentation of ordinary lighting, ambiance and projection (such as starry sky), thereby enhancing the product's market competitiveness.

[0004] To achieve the above objectives, this utility model provides a multi-functional lighting fixture suitable for multiple usage scenarios, comprising: Lamp holder; The first light source is disposed on the lamp holder; A lampshade assembly covers the first light source and is disposed on the lamp holder. The lampshade assembly consists of a first lampshade, a second lampshade, a third lampshade and a fourth lampshade arranged sequentially from the inside to the outside, with gaps between each lampshade. The second light source is disposed on the lamp holder and located between the first lamp cover and the second lamp cover or between the second lamp cover and the third lamp cover; The first lampshade is a film with a projected pattern, the second and third lampshades are electronically controlled dimming films that can switch between light scattering and transparent states, and the fourth lampshade is an outer lampshade made of transparent material.

[0005] The electrically controlled dimming film used in this invention is a conventional electrically controlled dimming product. When no electric field is applied to the electrically controlled dimming film, it exhibits light scattering; when an electric field is applied to the electrically controlled dimming film, it becomes transparent. The electrically controlled dimming film of this invention is preferably a polymer-dispersed liquid crystal (PDLC) film. For its product and preparation method, please refer to Chinese Patent "CN201911346420.4" which discloses a method for preparing a polymer-dispersed liquid crystal material based on monomers with rigid end structures, and Chinese Patent "CN201910705446.7" which discloses a method for preparing a polymer-dispersed liquid crystal thin film, etc.

[0006] As a further preferred embodiment of this utility model, the lamp holder is further provided with a motor and an annular component driven to rotate by the motor. The first light source is located at the center of the annular component, and the first lampshade is connected to the annular component. The annular component is used to drive the first lampshade to rotate relative to the first light source with the first light source as the center. When the lamp is used for projection and the first lampshade rotates relative to the first light source, a dynamic pattern is projected; otherwise, a static pattern is projected.

[0007] As a further preferred embodiment of this utility model, the first layer of lampshade is cylindrical, and the projected pattern is disposed on the cylindrical wall and / or top of the first layer of lampshade.

[0008] As a further preferred embodiment of this utility model, the second lampshade and the third lampshade are cylindrical or square, with the second lampshade having a larger volume than the first lampshade and the third lampshade having a larger volume than the second lampshade, so that the first and second lampshades are completely covered by the second and third lampshades respectively.

[0009] As a further preferred embodiment of this utility model, the fourth lampshade is made of transparent plastic or transparent glass, and is cylindrical, square, spherical or other shapes. The fourth lampshade serves as a light-transmitting protective cover to protect the light source, inner lampshade and middle lampshade inside, such as dustproof, waterproof and impact-resistant.

[0010] As a further preferred embodiment of this utility model, the first light source and the second light source are LED beads, and even more specifically, the light source is an LED bead with adjustable brightness and color.

[0011] As a further preferred embodiment of this utility model, the lamp holder is equipped with a controller, and the first light source, the second light source, and the electronically controlled dimming diaphragm are all controlled by the controller. Furthermore, the controller can communicate with external devices via its built-in wireless communication module, which can be one or more of a Wi-Fi module, Bluetooth module, ZigBee module, LoRa module, or cellular communication module.

[0012] As a further preferred embodiment of this utility model, the lamp holder is provided with a control switch, power interface, etc., which are connected to the controller.

[0014] The multifunctional and multi-scenario lighting fixture of this utility model, by adopting the above technical solution, has the following beneficial effects: (1) This utility model achieves seamless switching between three modes—ordinary lighting (full scattering), ambient lighting (internal projection), and starry sky projection (multi-layer transmission, external projection)—through the coordinated control of the electronically controlled dimming film and the light source, meeting the needs of multiple scenarios such as home, business, and entertainment; for example, when reading at night, the projection function is turned off as a lighting lamp, the ambient light is turned on to enhance the mood during a party, and the children's room scene is switched to the starry sky projection mode.

[0015] (2) This utility model can not only realize the projection of static patterns, but also generate dynamic rotating projection effects (such as falling snowflakes and rotating star trails) by combining the film pattern with the axial rotation of the first layer of lampshade, thereby enhancing visual appeal.

[0016] (3) This utility model adopts a layered multi-lampshade design (electronically controlled dimming film + film) to achieve precise light control: softening the lighting in the scattering state and ensuring the clarity of the projection in the transparent state; the first light source is located in the center of the inner side of the lampshade, and the second light source is located on the outer side of the film to avoid light path interference between the projection and lighting functions.

[0017] (4) This utility model can replace traditional lighting lamps, projectors, decorative lamps and other products with a single device, reducing the user's purchase and maintenance costs.

[0018] (5) The lighting technology solution of this utility model can be extended to smart home systems (such as linked voice control, APP preset scenes), enhancing product competitiveness, such as wireless communication connection between the lighting fixture of this utility model and smart electronic devices such as TVs, micro projectors, audio equipment, computers, electronic watches, and mobile phones.

[0023] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Terms such as "upper," "lower," "left," "right," "middle," and "one" used in the preferred embodiments are merely for clarity of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of the present invention.

[0025] Example 1: like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a multi-functional, multi-scenario lighting fixture, which includes a lamp holder 1, a first light source 3, a second light source 4, and a first lampshade 21, a second lampshade 22, a third lampshade 23, and a fourth lampshade 24 arranged sequentially from the inside out to form a lampshade assembly 2. The first lampshade 21, the second lampshade 22, the third lampshade 23, and the fourth lampshade 24 of the lampshade assembly 2 are all cylindrical with progressively increasing dimensions, and are separated by gaps to form a multi-layered nested structure. The materials of each layer of the lampshade assembly 2 vary according to their function. The first lampshade 21 is a film with a starry sky projection pattern, located on the cylindrical wall and top of the first lampshade 21. The second and third lampshades 22 and 23 are electrically controlled dimming films that can switch between light scattering and transparent states. The fourth lampshade 24 is made of transparent plastic.

[0026] It should be noted that the use of film for lamp projection is a conventional technology, and the specific settings of the projection pattern and the corresponding projection principle will not be elaborated here; in addition, depending on the projection requirements, the projection pattern can be set at any position on the cylindrical wall or top of the first lampshade 21.

[0027] The first light source 3 is located at the center of the lamp holder 1 and covers the inside of the first lamp cover 21. The second light source 4 is located on the lamp holder 1 and between the first lamp cover 21 and the second lamp cover 22. Both the first light source 3 and the second light source 4 are LED beads with adjustable brightness and color, and the second light source 4 is composed of multiple such LED beads evenly distributed in a ring.

[0028] In order to achieve dynamic projection, the lamp holder 1 is also equipped with a motor and a ring component driven by the motor to rotate. The first light source 3 is located at the center of the ring component, and the first lamp cover 21 is connected to the ring component. The ring component is used to drive the first lamp cover 21 to rotate relative to the first light source 3 with the first light source 3 as the center.

[0029] Specifically, the lamp holder 1 is also equipped with a controller, which serves as the control center to achieve the following functions: control the opening of the first light source 3 and the second light source 4 and adjust their brightness and color; control the on / off of the electric field of the electronic dimming film to switch the second and third layer lamp covers between light scattering and transparent states; control the motor to drive the ring component to rotate the first layer lamp cover 21, so that the projected pattern presents a dynamic effect.

[0030] Specifically, the lamp holder 1 is also equipped with a power interface 5 and a control switch. The power interface 5 is used to connect an external power supply, and the control switch is used to control the switching on and off and the operating status of the lamp. In a specific embodiment, the control switch includes a power interface 6, an LED switch 7, a rotary switch 8, and an electro-optical membrane switch 9. The power interface 6 is used to control the switching on and off of the total power supply of the lamp, the LED switch 7 is used to adjust the first light source 3 and the second light source 4, the rotary switch 8 is used to turn on the motor, and the electro-optical membrane switch 9 is used to control the on / off of the electric field output to the electro-optical dimming diaphragm.

[0031] Example of work status: When the first light source 3 is turned on, the power supply of either the electronically controlled dimming film of the second lampshade 22 or the third lampshade 23 is turned on, that is, either the second lampshade 22 or the third lampshade 23 is in a transparent state. At this time, the light emitted by the first light source 3 passes through the first lampshade 21 and projects the pattern on the film onto the unlit second lampshade 22 or the third lampshade 23 in a light scattering state. That is, the pattern is projected onto the lamp itself, and the lamp is an ambient light at this time. By rotating the first lampshade 21, the axial dynamic rotation of the projected pattern can be achieved.

[0032] When the first light source 3 is turned on, the power supply of the electronically controlled dimming films of the second lampshade 22 and the third lampshade 23 is also turned on, that is, the second lampshade 22 and the third lampshade 23 are both transparent. At this time, the light emitted by the first light source 3 passes through the first lampshade 21, so that the pattern on the film is projected onto the outside of the lamp, such as the wall and roof of the building where the lamp is located. At this time, the lamp is a starry sky projection lamp. By rotating the first lampshade 21, the axial dynamic rotation of the projected pattern can be achieved.

[0033] When the second light source 4 is turned on, either the power supply of the electronically controlled dimming film of the second lampshade 22 and the third lampshade 23 is turned on, or the power supply of the electronically controlled dimming film of the second lampshade 22 and the third lampshade 23 is not turned on, that is, there is at least one lampshade outside the second light source 4 in a light scattering state. At this time, since the light source is located outside the first lampshade 21, the pattern on the film cannot be projected normally, and the lamp is a normal lighting lamp.

[0034] As described above, this lamp can switch between ordinary lighting, ambient lighting, and starry sky projection lighting, meeting the needs of different scenarios and enhancing the emotional value for users.

[0035] Furthermore, by controlling the brightness and color of the LED beads, the brightness and color of the starry sky projection can be adjusted to achieve more colorful and varied effects.

[0036] Example 2 The difference from Embodiment 1 is that the second light source is disposed on the lamp holder and located between the second and third lampshades. The rest of this embodiment is the same as Embodiment 1 and will not be repeated here.

[0037] In this embodiment, by combining and controlling the electronically controlled dimming films of the first light source, the second light source, and the second and third lampshades, the switching between ordinary lighting, ambient lighting, and starry sky projection lighting can also be achieved. Furthermore, in the case of ordinary lighting, the electronically controlled dimming film of the third lampshade outside the second light source can be switched to a transparent or heat dissipation state to adjust the brightness of the lighting.

[0038] Although specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and various changes or modifications can be made to these embodiments without departing from the principles and essence of the present invention. The scope of protection of the present invention is defined only by the appended claims.
