The present invention relates to table lamps, and more particularly to a table lamp structure that exhibits an effect of light and shadow.
In the large indoor environment of a household, lighting is largely relying on lighting fixture mounted to the ceiling. Other corners of the house are often arranged with decorating lights and desk lamps, generally for decoration purposes. Such decoration lighting provides, in addition to illumination, an effect of enhancing the atmosphere of the environment.
An example is disclosed in U.S. Pat. No. 9,222,663 B1 owned by the present applicant, in which a light-transmitting three-dimensionally shaped decoration is additionally attached to a top of a water lamp, and a light-emitting element is provided in the interior thereof, so that upon energization, in addition to flowing of a low boiling point liquid contained in a main body of the water lamp and lighting emitting from a base, the light source inside the top-side shaped decoration is also projected outward to create a glaring visual effect. However, such a decoration luminary structure is functionally limited to variation of lighting on the outside of the main body of the water globe.
Commonly known table lamps or floor lamps are generally designed to provide the sole function of light projection, and are not intended for providing a visual effect to create or enhance the surrounding environment. Other art lamps that are advantageous in light of unique shapes may have an effect of beautifying an indoor environment, yet it is generally not available for such lamps to feature a unique art shape, while at the same time enable variation of lighting shadows. Thus, a table lamp would be more eye-catching for the general public if, in addition to having features in both decoration and lighting, such a lamp is provided with advantages of playfulness exhibited in other parts or a breakthrough to outside visual perception.
In view of the above, the primary objective of the present invention is to provide a light-and-shadow table lamp structure, which comprises:
a lamp base, which has an interior space in which an electrical control unit is arranged, the electrical control unit comprising at least one light-emitting element arranged at a top of the lamp base;
a shadow projecting plate, which is arranged above the at least one light-emitting element to correspond thereto, the shadow projecting plate comprising a light-transmitting pattern; and
a lampshade, which is arranged on the top of the lamp base and surrounds and circumferentially encloses the shadow projecting plate and the at least one light-emitting element.
Light from the at least one light-emitting element projects outward to cast a shadow of the light-transmitting pattern of the shadow projecting plate onto an external object so as to achieve an effect of varying light projection to form a light shadow at the outside.
Referring to
The lamp base (2) is of an inverted T-shaped structure includes a bottom part and a supporting post fixed to the bottom part and extending upward therefrom. The lamp base (2) has an interior space in which an electrical control unit (5) is arranged. The electrical control unit (5) comprises a circuit board (51), a power supply portion (52), a plurality of light-emitting elements (53), and a switch (54). The power supply portion (52), each of the light-emitting elements (53), and the switch (54) are in electrical connection with the circuit board (51). The present invention imposes no constraint to the quantity of the light-emitting elements (53) except that the number has to be at least one; an example provided in the drawings shows multiple light-emitting elements for illustration, but not limitative, purposes. Each of the light-emitting elements (53) can be an LED light or a tungsten filament light bulb. The present invention does not limit the type of the power supply portion (52), which can be electric main or a battery. In the instant embodiment, the power supply portion (52) is disposed in the bottom of the lamp base (2), while the circuit board (51) is arranged at a top of the lamp base (2). The lamp base (2) is provided with a channel (21) extending in an axial direction in order to accommodate electrical wires (L). Each of the light-emitting elements (53) is arranged to irradiate toward a top side. The lamp base (2) is further provided, on the top thereof, with a fixing frame (22). The fixing frame (22) functions to support the lampshade (4), and thus, a top of the fixing frame (22) is set spacing from the top of the lamp base (2) by a predetermined distance.
The shadow projecting plate (3) is arranged to correspond to the light-emitting elements (53) at a location above the light-emitting element. The shadow projecting plate (3) comprises a light-transmitting pattern (31), and a moon-and-star pattern is taken as an example for illustration in the instant embodiment, but the present invention is not limited thereto. If desired, a user may change the light-transmitting pattern (31) to different patterns including flowers, landscape, and texts.
The lampshade (4) is positioned on and mounted to the top of the fixing frame (22) of the lamp base (2) and circumferentially encloses a periphery of the shadow projecting plate (3) and the light-emitting elements (53). The lampshade (4) is formed with a projection hole (41) corresponding to the shadow projecting plate (3). The lampshade (41) may be further formed with a light-penetrating pattern (42), and in the instant embodiment, the light-penetrating pattern (42) is also a moon-and-star pattern to match up with the light-transmitting pattern (31), but not limited thereto. The shadow projecting plate (3) can be integrally formed with the top end of the lampshade (4), or may alternatively be implemented in the way shown in the drawings of the instant embodiment, where the top of the lampshade (4) is formed with the projection hole (41), and the top of the lampshade (4) is provided with a receiving or receptacle portion (43) for receiving and retaining the shadow projecting plate (3) therein. The receiving or receptacle portion (43) is in communication with the projection hole (41) to allow the shadow projecting plate (3) to be positioned and mounted in the receiving or receptacle portion (43) in a removable manner.
Following the above, the present invention does not put constraint on light-transmitting pattern (31) and the light-penetrating pattern (42) in respect of shape, structure, and outside appearance thereof, and in an example, as shown in the enlarged view of a portion of the lampshade (4) provided in
As such, light from each of the light-emitting elements (53) may transmit through the light-transmitting pattern (31) of the shadow projecting plate (3) to project through the projection hole (41) to an outside object, such as a wall, a ceiling, and a piece of furniture. Further, light from each of the light-emitting elements (53) also penetrates through the light-penetrating pattern (42) of the lampshade (4), so that in addition to lighting, the table lamp (1) also provides a function of shadow casting through light projection. Further, the circuit board (51) is operable to control variation of light color for each of the light-emitting elements (53), so that the shadow casting through light projection may become dazzling or glaring. It is noted that if desired, the user may change or replace the shadow projecting plate (3) with a different pattern in order to change the environmental atmosphere with different visual perceptions.
Referring to
In the instant embodiment, the shadow projecting plate (3) is structured such that the light-transmitting pattern (31) includes four groups of festival or holiday symbols spaced from each other and is fixed by bolts or screws to the top side of the lamp cup (57). The rotatable plate (56) is structured such that a top surface and a bottom surface are provided with a plurality of first lenses (561) that are arranged at intervals and correspond to the light-transmitting pattern (31).
The lamp cup (57) is light transmittable and comprises a platform (571) and a plurality of cup bodies (572). Each of the cup bodies (572) is arranged on a bottom side of the platform (571) and is extended toward a respective one of the light-emitting elements (53), and is formed with an accommodation hole (573), such that each of the accommodation holes (573) receives the respective one the light-emitting elements (53) therein to have the light-emitting element housed therein. Mounted on a top side of the platform (571) to correspond each of the cup bodies (572) is a second lens (574), and each of the second lenses (574) faces the light-transmitting pattern (31) of the shadow projecting plate (3).
