The socket members 43 are retained respectively on the first and second anchoring surfaces 423, 424 of the mounting bracket 42, and are adapted for mounting a respective light bulb 44, such as an incandescent lamp, thereon.
Each of the insulated conductive cord members 47 has a first end portion connected electrically to a respective one of the socket members 43 via a respective one of the passage holes in the anchoring surfaces 423, 424, and a second end portion extending into the closed accommodating space 45 via a respective one of the cord holes 412 in the partition plate 41.
The power cord member 60 has a first connecting end 61 adapted to be connected electrically to a power source (not shown), and a second connecting end 60 extending into the closed accommodating space 45 of the containment member 40 and connected electrically to the second end portions of the insulated conductive cord members 47.
In the preferred embodiment, the mounting portion 400 of the containment member 40 is formed with a mounting post 401 that projects into the closed accommodating space 45 and that has the center portion 411 of the partition plate 41 and the middle portion 420 of the mounting bracket 42 mounted thereon. The lamp shade 5 has one end 51 extending into the open accommodating space 46 of the containment member 40, and is mounted detachably on the partition plate 41. The partition plate 41 further has a pair of screw posts 413 that extend into the open accommodating space 46 of the containment member 40. The lamp shade 5 has a skirt portion 53 with a mounting side 50 that extends into the open accommodating space 46, and that is formed with two fastening lugs 54 for mounting on the screw posts 413 of the partition plate 41 such that the skirt portion 53 diverges in a direction away from the partition plate 41.
Preferably, the support member 3 includes a lamp base 2 and an upright lamp post 30 that has a lower end 32 mounted on the lamp base 2 and an upper end 31 with the mounting portion 400 of the containment member 40 mounted thereon. The lamp post 30 is formed with an axially extending cord passage for extension of the first connecting end 60 of the power cord member 6.
The mounting post 401 is preferably formed with an external thread such that the mounting post 401 can extend through the center portion 411 of the partition plate 41, and a through hole 42H in the middle portion 420 of the mounting bracket 42. An internally and externally threaded first locking nut 48 is mounted on the mounting post 401, and has an outwardly and radially extending abutment flange 480 to abut against the mounting bracket 42 around the hole 420H thereof in order to retain the mounting bracket 42 as well as the partition plate 41 in the containment member 40. A second locking nut 49 is threaded on the first nut 48 to enhance positioning of the mounting bracket 42 on the partition plate 41 such that once the mounting bracket 42 is installed in the open accommodating space 46, the mounting bracket 42 is exposed outwardly of the opening 57 (see
Another aspect to note is that, the insulated conductive cord member 47 and the power cord member 60 are concealed in the closed accommodating space 46 of the containment member 40. As such, accidental touching of the cord members 47, 60 is consequently avoided to provide safety for the user of the lighting apparatus of the present invention.
With further reference to FIGS. 6 and 7, it can be appreciated that the mounting bracket 42 includes a middle portion 420 that mounts to the top of the lamp and is flanked by end portions 421,422 that anchor light sockets. In order to prevent the bulbs from clashing with one another, the end portions 421,422 are bent upwardly from the top of the lamp at an angle such that the light sockets (and any bulbs seated therein) project from the top of the lamp at an acute angle (α, β). In addition, the end portions 421,422 are bent along lines which locate the light sockets so that light bulbs seated in the respective sockets pass one another without contact. In the embodiment of FIGS. 3 and 4, the mounting bracket 42 has end portions 421,422 bent at an unspecified angle. In the embodiment of FIG. 7, the end portions 421,422 are bent along parallel lines at an angle θ relative to a line L that is perpendicular to the direction of elongation of the mounting bracket. In certain preferred embodiments, the acute angle (α, β) ranges between 38 to 52 degrees, while the predetermined angle ranges between 16 to 26 degrees.
As best shown in
With the present invention thus explained, it is apparent that numerous modifications and variations can be made without departing from the scope and spirit of this invention. It is therefore intended that this invention be limited only as indicated in the appended claims.
