The present invention relates to a lamp structure, particularly to one that has a glass tube film-coated with images to display 3D visual effects by projection.
Lamps are designed for indoor illumination. Usually they are placed on desks, hallways, and corners to maximize its lighting function. Nowadays they have already become an essential part in our daily life. Consequently, their appearances have also come into our sights. The manufacturers have put great efforts to pursue different appearances and styles based on the basic structures of lamps, trying to become more competitive in the fields. However, these days lamps with different designs on the appearances in the markets tend to be considered normal without any creativity.
Glass tubes with 3D images are recently developed artworks. Various 3D images are coated on an inner wall of the glass tubes, allowing which to display vivid visual effects by simple projection; but there is a shortcoming—glass tubes are fragile, making it easily broken when engaged with other structures. Therefore, the inventor is trying to overcome the problem in order to combine the unique visual effects from the glass tubes with lamps structures.
A primary object of the present invention is to provide a lamp structure that is able to stably fix a film-coated glass tube on a supporting element and meanwhile display 3D images by projections for lighting and displaying special visual effects at the same time.
To achieve the objects mentioned above, the present invention comprises a base including a supporting element thereon and an axial through hole arranged from the supporting element through the base; a film-coated glass tube disposed on the supporting element with an opening on a top thereof, a bottom surface and a through hole at a bottom thereof, and an inner space therein, said film-coated glass tube further having 3D images on an inner wall thereof; an engaging device including a body and a fixing element, said body having a bowl-shaped bottom and a penetrating hole to be engaged in the supporting element, aligning the penetrating hole with the axial through hole; the bottom surface of the film-coated glass tube is fixedly disposed between the body and the fixing element, thereby further fixing the film-coated glass tube on the supporting element; a cover disposed on the film-coated glass tube; a hollow tube connecting from a top of the cover down through the film-coated glass tube to a bottom of the base and being fixed by a wing nut for a first wire to be connected to the cover therethrough; a projection bulb engaged a first bulb holder which is linked to the hollow tube in a middle section thereof and connected to the first wire, so as to project lights on the film-coated glass tube; and a lighting bulb engaged a second bulb holder on the cover which is connected to the first wire for illumination.
Furthermore, the projection bulb is a LED bulb for the purpose of energy saving and longer durability of the bulb. A lampshade is further disposed on the lighting bulb and the second bulb holder; with different design of the lampshade, the lamp is able to present different styles for decoration.
In an embodiment, the hollow tube is formed by a first tube linked to a second tube with a connecting section, said second tube having a second external threaded section at a bottom thereof for the wing nut to fixedly screw under a bottom of the base and said connecting section being electrically connected to the first bulb holder via a second wire.
In another embodiment, the hollow tube is formed by a first tube linked to a second tube with a connecting section and a third tube engaged with the second tube, said third tube having a fourth external threaded section at a bottom thereof for the wing nut to fixedly screw under a bottom of the base and said connecting section being electrically connected to the first bulb holder via a second wire, the body further including an inner flange for fixed engaging the third tube thereon by a positioning ring and a nut.
With structures disclosed above, the present invention has the engaging device to stably fix the film-coated glass tube on the supporting element to prevent from breakage of the glass tube. Also, the glass tube has 3D images coated on the inner wall to produce beautiful visual effects by projection while lighting up the surrounding area.
Referring to
The base 10 includes a supporting element 11 thereon and an axial through hole 12 arranged from the supporting element 11 through the base 10.
The film-coated glass tube 20 is disposed on the supporting element 11 with an opening 23 on a top thereof, a bottom surface 241 and a through hole 242 at a bottom thereof, and an inner space 21 therein. The film-coated glass tube 20 further has 3D images on an inner wall 22 thereof.
The engaging device 30 includes a body 31 and a fixing element 32. The body 31 has a bowl-shaped bottom 311 and a penetrating hole 312 to be engaged in the supporting element 11, aligning the penetrating hole 312 with the axial through hole 12. The bottom surface 241 of the film-coated glass tube 20 is fixedly disposed between the body 31 and the fixing element 32, thereby further fixing the film-coated glass tube 20 on the supporting element 11.
The cover 50 is disposed on the opening 23 of the film-coated glass tube 20. The hollow tube 40 is formed by a first tube 41a linked to a second tube 41b with a connecting section 45. The first tube 41a is linked to a top end of the cover 50, and the second tube 41b has a second external threaded section 411 at a bottom thereof and passes through the film-coated glass tube 20 to a bottom of the base 10 to be screwed and fixed by a spring washer 141, a plain washer 142 and a wing nut 143. The cover 50 is further connected to a first wire 42 which passes through the hollow tube 40 to a bottom of the base 10. A projection bulb 43 and a first bulb holder 44 are arranged in the inner space 21 of the film-coated glass tube 20 and linked to the hollow tube 40 in a middle section thereof, connected to the first wire 42 via a second wire 421 for projection; in this embodiment, the projection bulb 43 is a LED bulb. A lighting bulb 52 and a second bulb holder 51 are disposed on the cover 50 and connected to the first wire 42 for illumination.
In
In short, the present invention has the engaging device 30 to stably fix the film-coated glass tube 20 on the supporting element 11 to prevent from breakage of the glass tube. Also, the glass tube has 3D images coated on the inner wall to produce beautiful visual effects by projection while lighting up the surrounding area, and it is applicable with different lampshades for different styles and appearances.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
Accordingly, the invention is not to be limited except by the appended claims.
