Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a lamp. Background Technology

[0002] Abyss lights, primarily based on the principle of optical reflection, achieve a deep-sea visual effect through a combination of a semi-transparent layer, a plane mirror (or a total reflection mirror), and a light source. Figure 1 As shown, the specific technical solution is as follows:

[0003] Its structure is as follows: the outermost layer is a lampshade; inside, from near to far, are a semi-transparent mirror, a light source (usually an LED strip attached to the inner wall of the lampshade), and a one-way mirror. Light emitted from the light source reaches the one-way mirror and the semi-transparent mirror. The one-way mirror reflects most of the light back to the semi-transparent mirror, while the semi-transparent mirror transmits and reflects some light back to the one-way mirror. In this way, the light continuously reflects between the semi-transparent mirror and the one-way mirror, creating an infinitely superimposed mirror image when viewed from the front, thus presenting an abyss-like visual effect. Theoretically, the stronger the light source, the lower the transmittance of the semi-transparent mirror, the more reflections occur, and the stronger the abyss effect.

[0004] However, traditional abyss lights only display static visual effects, making it difficult to switch between abyss lights and ordinary lighting, and also unable to present specific pattern changes that vary with temperature.

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0046] Example 1:

[0047] like Figure 2 As shown, this embodiment is a lamp with a state adjustment film 5 (electronically controlled dimming film): the outermost layer is a lampshade; the inner layers, from near to far, are the electronically controlled dimming film, the light source 2 (an LED light strip attached to the inner wall of the lampshade), and the light reflective layer 3 (a one-way mirror). The side of the state adjustment film 5 facing the light reflective layer 3 has a light-reflecting function.

[0048] After the light source is turned on, an electric field is applied to or not applied to the electronically controlled dimming film to make it transparent. After the light is emitted from the light source, it reaches the one-way mirror. The one-way mirror reflects most of the light back to the dimming film. The dimming film transmits some of the light and reflects some of the light back to the one-way mirror. In this way, the light is continuously reflected between the dimming film and the one-way mirror. When the lamp is viewed from the front, an infinitely superimposed mirror image is formed, thus presenting a visual effect like an abyss.

[0049] After the light source is turned on, by applying or not applying an electric field to the electronically controlled dimming film to make it in a light scattering state, the light cannot be continuously reflected between the semi-transparent and semi-reflective mirror and the one-way mirror. When the lamp is viewed from the front, it cannot form an infinitely superimposed mirror image, thus presenting the visual effect of ordinary lighting.

[0050] The aforementioned electronically controlled dimming film can be customized with patterns using laser engraving technology.

[0051] Example 2:

[0052] like Figure 3 As shown, this embodiment is a lamp with a pattern display film 6 (temperature-controlled dimming film). The outermost layer is a lampshade; the inner layers, from near to far, consist of the pattern display film 6 (temperature-controlled dimming film), the light source 2 (an LED light strip attached to the inner wall of the lampshade), and the light reflective layer 3 (one-way mirror). The pattern display film 6 has a light-reflecting function on the side facing the light reflective layer 3.

[0053] After the light source is turned on, the light shines out from the light source and reaches the one-way mirror and the status pattern display film. The one-way mirror reflects most of the light back to the status pattern display film. The status pattern display film transmits some of the light and reflects some of the light back to the one-way mirror. In this way, the light is constantly reflected between the status pattern display film and the one-way mirror. When the lamp is viewed from the front, an infinitely superimposed mirror image is formed, thus presenting a visual effect like an abyss.

[0054] When the light source is turned on, the heat emitted by the LED light accumulates over time, causing the temperature inside the lampshade to rise to a certain level and reach the temperature threshold of the temperature-controlled dimming film. The film then displays a pre-designed pattern. When viewed from the front, the pattern on the temperature-controlled film has a layered effect, and it also intelligently adjusts the pattern according to temperature. When the power is turned off, the temperature inside the lampshade decreases, and the pattern on the temperature-controlled dimming film disappears, along with the layered effect.

[0055] The edges of the aforementioned temperature-controlled dimming film must not obstruct the light emitted by the light source. The surface of the aforementioned temperature-controlled dimming film can be customized with color patterns using printing technology.

[0056] Example 3:

[0057] like Figure 4 and Figure 5 As shown, this embodiment is a lamp that simultaneously has a status adjustment film 5 (electronic dimming film) and a pattern display film 6 (temperature-controlled dimming film). In this embodiment, the order of the status adjustment film 5 and the pattern display film 6 can be interchanged.

[0058] The outermost layer is the lampshade, and from the outside in, they are: pattern display film 6, status adjustment film 5, light source 2, and light reflection layer 3 (e.g., Figure 4 As shown), the state adjustment film 5 faces the outer surface of the light reflective layer 3 and has a light-reflecting function. Alternatively, the lampshade can be arranged from the outside in as follows: state adjustment film 5, pattern display film 6, light source 2, light reflective layer 3 (as shown). Figure 5 As shown in the diagram, the pattern shows that the film 6 has a light-reflecting function on the outer surface of the reflective layer 3.

[0059] After the light source is turned on, the electronically controlled dimming film is made transparent by applying or not applying an electric field. After the light is emitted from the light source, it reaches the one-way mirror and the status adjustment film or pattern display film. The one-way mirror reflects most of the light back to the status adjustment film or pattern display film (depending on which one is closer to the one-way mirror). The status adjustment film or pattern display film partially transmits and partially reflects the light back to the one-way mirror. In this way, the light is continuously reflected between the status adjustment film or pattern display film and the one-way mirror, which has the effect of an abyss light.

[0060] After the light source is turned on, by applying or not applying an electric field to the electronically controlled dimming film to make it in a light scattering state, the light cannot be continuously reflected between the state adjustment film or pattern display film and the one-way mirror. When the lamp is viewed from the front, it cannot form an infinitely superimposed mirror image, thus presenting the visual effect of ordinary lighting.

[0061] Meanwhile, as time increases after the light source is turned on, the heat emitted by the light source accumulates, and the temperature inside the lampshade rises until it reaches the temperature threshold of the pattern display film. The pattern display film then displays a pre-designed specific pattern. When the lamp is viewed from the front, the pattern on the pattern display film has a deep overlay effect, and it also has the effect of intelligently regulating the pattern based on temperature. After the power is turned off, the temperature inside the lampshade decreases, the pattern on the pattern display film disappears, and the pattern overlay effect disappears.

[0062] The edges of the aforementioned patterned display film must not obstruct the light emitted by the light source. The surface of the aforementioned patterned display film can be customized with color patterns using printing technology.

[0063] The lamp also includes a control module, which is at least one of a power switch, a touch sensor, a voice recognition module, and a wireless receiving module. The control module is electrically connected to the driving power supply of the light source 2 and / or the state adjustment film 5 to control the state of the lamp.

[0064] Example 4:

[0065] like Figure 6 As shown, this embodiment is a lamp with a state adjustment film 5 (electronically controlled dimming film): the outermost layer is a lampshade; the inner layers, from near to far, are a semi-transparent layer 4 (semi-transparent and semi-reflective mirror), an electronically controlled dimming film, a light source 2 (an LED light strip attached to the inner wall of the lampshade), and a light reflection layer 3 (one-way mirror). After the light source is turned on, the electronically controlled dimming film is made transparent by applying or not applying an electric field. After the light is emitted from the light source, it reaches the one-way mirror and the semi-transparent and semi-reflective mirror. The one-way mirror reflects most of the light back to the semi-transparent and semi-reflective mirror, while the semi-transparent and semi-reflective mirror transmits some light and reflects some light back to the one-way mirror. In this way, the light is continuously reflected between the semi-transparent and semi-reflective mirror and the one-way mirror. When the lamp is viewed from the front, an infinitely superimposed mirror image is formed, thus presenting a visual effect like an abyss.

[0066] After the light source is turned on, by applying or not applying an electric field to the electronically controlled dimming film to make it in a light scattering state, the light cannot be continuously reflected between the semi-transparent and semi-reflective mirror and the one-way mirror. When the lamp is viewed from the front, it cannot form an infinitely superimposed mirror image, thus presenting the visual effect of ordinary lighting.

[0067] The aforementioned electronically controlled dimming film can be customized with patterns using laser engraving technology.

[0068] Example 5:

[0069] like Figure 7 As shown, this embodiment is a lamp with a pattern display film 6 (temperature control dimming film). The outermost layer is a lampshade. The inner layers, from near to far, are a semi-transparent layer 4 (semi-transparent and semi-reflective mirror), a pattern display film 6 (temperature control dimming film), a light source 2 (an LED light strip attached to the inner wall of the lampshade), and a light reflection layer 3 (one-way mirror). Alternatively, the inner layers, from near to far, are a pattern display film 6 (temperature control dimming film), a semi-transparent layer 4 (semi-transparent and semi-reflective mirror), a light source 2 (an LED light strip attached to the inner wall of the lampshade), and a light reflection layer 3 (one-way mirror).

[0070] When the light source is turned on, the light rays are emitted from the light source and reach the one-way mirror and the semi-transparent mirror. The one-way mirror reflects most of the light rays back to the semi-transparent mirror, while the semi-transparent mirror transmits some light rays and reflects some light rays back to the one-way mirror. In this way, the light rays are continuously reflected between the semi-transparent mirror and the one-way mirror. When the light fixture is viewed from the front, an infinitely superimposed mirror image is formed, thus presenting a visual effect like an abyss.

[0071] When the light source is turned on, the heat emitted by the LED light accumulates over time, causing the temperature inside the lampshade to rise to a certain level and reach the temperature threshold of the temperature-controlled dimming film. The film then displays a pre-designed pattern. When viewed from the front, the pattern on the temperature-controlled film has a layered effect, and it also intelligently adjusts the pattern according to temperature. When the power is turned off, the temperature inside the lampshade decreases, and the pattern on the temperature-controlled dimming film disappears, along with the layered effect.

[0072] The edges of the aforementioned temperature-controlled dimming film must not obstruct the light emitted by the light source. The surface of the aforementioned temperature-controlled dimming film can be customized with color patterns using printing technology.

[0073] Example 6:

[0074] like Figure 8 and Figure 9 As shown, this embodiment is a lamp that simultaneously has a state adjustment film 5 (electronically controlled dimming film) and a pattern display film 6 (temperature-controlled dimming film). In this embodiment, the positions of the state adjustment film 5, the light reflective layer 3, and the pattern display film 6 are adjustable.

[0075] The outermost layer is the lampshade, and from the outside in, they are: 4. Semi-transparent layer; 6. Pattern display film; 5. Status adjustment film; 2. Light source; 3. Light reflection layer (e.g.) Figure 8(as shown); or the lampshade, from the outside to the inside, consists of a pattern display film 6, a semi-transparent layer 4, a status adjustment film 5, a light source 2, and a light reflection layer 3 (as shown). Figure 5 (as shown); or the lampshade, from the outside to the inside, is in the following order: status adjustment film 5, pattern display film 6, semi-transparent layer 4, light source 2, light reflection layer 3; or the lampshade, from the outside to the inside, is in the following order: pattern display film 6, status adjustment film 5, semi-transparent layer 4, light source 2, light reflection layer 3.

[0076] After the light source is turned on, the electronically controlled dimming film is made transparent by applying or not applying an electric field. After the light is emitted from the light source, it reaches the one-way mirror and the semi-transparent mirror. The one-way mirror reflects most of the light back to the semi-transparent mirror, and the semi-transparent mirror transmits some of the light and reflects some of the light back to the one-way mirror. In this way, the light is constantly reflected between the semi-transparent mirror and the one-way mirror, which has the effect of an abyss light.

[0077] After the light source is turned on, by applying or not applying an electric field to the state adjustment film to make it in a light scattering state, the light cannot be continuously reflected between the semi-transparent and semi-reflective mirror and the one-way mirror. When the lamp is viewed from the front, it cannot form an infinitely superimposed mirror image, thus presenting the visual effect of an ordinary lighting lamp.

[0078] Meanwhile, as time increases after the light source is turned on, the heat emitted by the light source accumulates, and the temperature inside the lampshade rises until it reaches the temperature threshold of the pattern display film. The pattern display film then displays a pre-designed specific pattern. When the lamp is viewed from the front, the pattern on the pattern display film has a deep overlay effect, and it also has the effect of intelligently regulating the pattern based on temperature. After the power is turned off, the temperature inside the lampshade decreases, the pattern on the pattern display film disappears, and the pattern overlay effect disappears.

[0079] The edges of the aforementioned patterned display film must not obstruct the light emitted by the light source. The surface of the aforementioned patterned display film can be customized with color patterns using printing technology.

[0080] The lamp also includes a control module, which is at least one of a power switch, a touch sensor, a voice recognition module, and a wireless receiving module. The control module is electrically connected to the driving power supply of the light source 2 and / or the state adjustment film 5 to control the state of the lamp.

[0081] The electro-controlled dimming film described in this application is prior art, prepared using the techniques described in Chinese Patent ZL201910403176.4 (a low-driving-voltage electro-controlled liquid crystal dimming film) or ZL 201810297473.0 (a method for preparing a PDLC film based on a liquid crystal / polymer composite material system). The temperature-controlled film is prepared using the techniques described in Chinese Patent ZL 201510791620.6 (a temperature-controlled dimming film and its stepwise polymerization preparation method).

[0082] Alternatives to dynamic graphic displays:

[0083] The switching between transparent and foggy states is achieved by using a temperature-controlled dimming film that is triggered by temperature. Alternatively, other methods can be used to achieve a similar effect of dynamic pattern display / hiding.

[0084] (1) Replacement of light-controlled film

[0085] Photochromic films or photosensitive atomizing films are used, and their state changes with the intensity of light.

[0086] The temperature-controlled dimming film is replaced with a photochromic film or a photosensitive atomizing film. When the abyss light is emitted, the film is triggered by the light to become a fog state, displaying a preset pattern; when the light is turned off or the light intensity is reduced, the film returns to transparency and the pattern is hidden.

[0087] (2) Electrochromic film (SPD dimming film and EC dimming film) as a replacement

[0088] Electrochromic films are used to change the color or transparency of the film by applying voltage.

[0089] Replace the temperature-controlled dimming film with an electrochromic film that is linked to the lamp's power supply system: when the lamp is turned on, the film is powered on and changes color / fogs to reveal the pattern; when the lamp is turned off, the power is cut off and the film returns to its original state.

[0090] (3) Temperature-sensitive ink replacement

[0091] Temperature-sensitive ink is printed onto a transparent substrate using a printing device, and its state changes with temperature.

[0092] The temperature-controlled dimming film is replaced with temperature-sensitive ink. When the abyss light is lit, the temperature-sensitive ink is triggered by temperature to change the pattern; when the light is turned off or the light intensity is reduced, the pattern is hidden.
