Description

Technical Field

[0001] This utility model relates to the field of projection lamps, and specifically to a new type of projection lamp. 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, the integration of dynamic dimming is insufficient, making it difficult to meet users' needs for multi-scene, multi-functional use. Second, the dimming structure design is unreasonable; traditional dimming methods often rely on frosted light-blocking panels to adjust brightness, failing to achieve rapid switching between frosted and transparent states. Third, the projection method is limited, making it difficult to switch the electric field of the projection on a near-field versus a far-field projection screen. In short, current starry sky projectors lack intelligent control functions, and to date, no fixtures utilize an electronically controlled dimming film 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 limited functions and lacking intelligent control, and realizes the integrated presentation of projection and ambient light, thereby enhancing the product's market competitiveness.

[0004] To achieve the above objectives, this utility model provides a novel projection lamp, comprising a lamp holder with a light source and an inner lampshade, a middle lampshade, and an outer lampshade mounted on the lamp holder and arranged sequentially along the optical axis. The inner lampshade is a film with a projection pattern, the middle lampshade is an electronically controlled dimming film that can switch between light scattering and transparent states, and the outer lampshade is 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 also provided with a motor and an annular component driven to rotate by the motor. The light source is located at the center of the annular component, and the inner lampshade is connected to the annular component. The annular component is used to drive the inner lampshade to rotate relative to the light source with the light source as the center.

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

[0008] As a further preferred embodiment of this utility model, the middle layer lampshade is cylindrical and has a larger volume than the inner layer lampshade, so that the inner layer lampshade is completely covered by the middle layer lampshade.

[0009] As a further preferred embodiment of this utility model, the outer lampshade is made of transparent plastic or transparent glass, and is cylindrical, square, spherical or other shapes. The outer 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 light source is an LED lamp bead, and even more specifically, the light source is an LED lamp bead with adjustable brightness and color.

[0011] As a further preferred embodiment of this utility model, the lamp holder is provided with a controller, and the light source and the electronically controlled dimming diaphragm are controlled by the controller.

[0012] As a further preferred embodiment of this utility model, the lamp holder is provided with a control switch connected to the controller on its side.

[0013] The novel projection lamp of this utility model, by adopting the above technical solution, has the following beneficial effects:

[0014] This invention provides an electrically controlled dimming film on the outside of a film with a projected pattern. By switching the state of the electrically controlled dimming film, the projection of the pattern on the film onto the electrically controlled dimming film and onto the wall and roof of the building where the lamp is located can be switched, thus meeting the needs of different scenarios and enhancing the emotional value for users.

[0022] 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.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a novel projection lamp, which includes a lamp holder 10 with a light source 4, and an inner lampshade 3, a middle lampshade 2, and an outer lampshade 1 mounted on the lamp holder 10 and arranged sequentially along the optical axis. The inner lampshade 3, middle lampshade 2, and outer lampshade 1 are cylindrical structures with progressively increasing dimensions. The inner lampshade 3 is a film with a projection pattern (such as a starry sky pattern), the middle lampshade 2 is an electrically controlled dimming film that can switch between light scattering and transparent states, the outer lampshade 1 is made of transparent material, and the light source 4 is an LED bead with adjustable brightness and color.

[0024] Specifically, the lamp holder 10 is also provided with a motor and a ring component driven by the motor to rotate. The light source 4 is located at the center of the ring component, and the inner lamp cover 3 is connected to the ring component to cover the light source 4. The ring component is used to drive the inner lamp cover 3 to rotate relative to the light source 4 with the light source 4 as the center.

[0025] The lamp holder 10 is also equipped with a controller, which serves as the control center to achieve the following functions: control the opening of the light source 4 and adjust its brightness and color; control the on / off of the electric field of the electronic dimming film to switch the middle lamp cover 2 between light scattering and transparent states; control the motor to rotate the inner lamp cover 3 through the ring component, so that the projected pattern presents a dynamic effect.

[0026] The lamp holder 10 is also equipped with a power interface 5 and a control switch. The power interface 5 is used to connect an external power adapter, and the control switch is used to control the switching on and off and the operating status of the projection lamp. Specifically, the control switch includes a power switch 6, an LED switch 7, a rotary switch 8, and an electro-optical control membrane switch 9. The power switch 6 is used to control the switching on and off of the main power supply of the projection lamp, the LED switch 7 is used to adjust the brightness or color of the LED beads, the rotary switch 8 is used to turn on the motor, and the electro-optical control membrane switch 9 is used to control the on / off of the electric field output to the electro-optical dimming membrane.

[0027] After the LED beads are turned on, the light emitted by the LEDs passes through the inner lampshade 3 with the projected pattern and first shines onto the middle lampshade 2. When the power to the electronically controlled dimming film of the middle lampshade 2 is off, the electronically controlled dimming film is in a light-scattering state, and the pattern on the film is projected onto the electronically controlled dimming film, which the user can see. When the power to the electronically controlled dimming film is on, the electronically controlled dimming film is transparent, and the user can see the pattern projected on the film on the wall or roof of the building where the light fixture is located. When the power to the electronically controlled dimming film is off, the projected pattern disappears from the wall and roof, and the pattern reappears on the electronically controlled dimming film. 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.

[0028] 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.
