ABSTRACT:
FIELD OF THE INVENTION
The invention relates to a lighting apparatus, more particularly to a lighting apparatus which has conductive cord members concealed within a closed accommodating space so as to provide safety when in use and which includes a lamp shade detachable therefrom such that a plurality of the lamp shades can be stacked one over another to facilitate storage and transport of the same.
DESCRIPTION OF THE RELATED ART
Referring to
FIG. 1
, a conventional lighting apparatus
1
includes a support member
11
, a lighting unit
14
mounted on the support member
11
, and a lamp shade
15
mounted on the lighting unit
14
.
As illustrated, the support member
11
includes a lamp base
10
and an upright post
110
having a lower end mounted on the lamp base
10
and an upper end supporting the lighting unit
14
thereon. The upright post
110
defines an axially extending cord passage therethrough. The lighting unit
14
includes a socket member
12
fixed on the upper end of the upright post
110
to receive a light bulb therein, and an insulated cord member
13
disposed in the cord passage. The insulated cord member
13
has one end connected electrically to the light bulb via the socket member
12
, and a second end adapted to be connected electrically to a power supply. The lamp shade
15
includes a top portion
151
, a skirt portion
152
extending downwardly and divergently from the periphery of the top portion
151
, and a retention member
150
extending downwardly from the top portion
151
and mounted on the upper end of the post
110
around the socket member
12
so as to shield the light bulb.
Some of the disadvantages that result from the use of the conventional lighting apparatus are as follows:
(1) There is only one socket member
12
in the conventional lighting apparatus for receiving a light bulb, such as an incandescent lamp. The light bulb accordingly provides a poor lighting effect. In case a halogen lamp is used, a better lighting effect can be achieved. However, the halogen lamp will raise the ambient temperature of the conventional lighting apparatus.
(2) The conventional lighting apparatus is bulky and therefore occupies a relatively large amount of space during storage and transport. Even though the lamp shade
15
can be detached relative to the upright post
110
, the lamp shades
15
of several conventional lighting apparatus cannot be stacked one over another due to the presence of the retention members
150
.
In a co-pending U.S. application, entitled “LIGHT FITTING FOR AN INCANDESCENT LIGHTING ARRANGEMENT”, filed on Jan. 23, 1998 by the applicant, there is disclosed a light fitting including a lampshade body, a mounting bracket, a pair of socket members, a pair of insulated conductive cord members, a containment member, a pair of incandescent bulbs, and a power cord member.
In another co-pending U.S. patent application Ser. No. 09/042,212, entitled “LIGHT FITTING FOR AN INCANDESCENT LIGHTING ARRANGEMENT”, filed on Mar. 13, 1998 by the applicant, there is disclosed a light fitting including a containment member, a mounting bracket, a pair of socket members, and a lampshade body.
SUMMARY OF THE INVENTION
The object of this invention is to provide a lighting apparatus which includes a pair of light bulbs that can provide a lighting effect comparable to that of a halogen lamp with the same wattage as the light bulbs, and a lamp shade that can be easily detached from a containment member such that a plurality of the lamp shades can be stacked one over another to facilitate storage and transport of the same.
Another object of the present invention is to provide a lighting apparatus which has cord members concealed within a closed accommodating space of the lighting apparatus such that accidental touching thereof can be avoided.
Accordingly, the lighting apparatus of the present invention includes a support member, a lighting unit mounted on one end of the support member, and a lamp shade mounted on the lighting unit. The lighting unit includes a containment member having a mounting portion mounted on the support member, a flared wall portion extending from a periphery of the mounting portion in a first direction away from the support member, and a partition plate disposed inside the flared wall portion in a second direction transverse to the first direction so as to define a closed accommodating space on one side of the partition plate proximate to the mounting portion, and an open accommodating space on the other side of the partition plate. The partition plate has a center portion and a pair of cord holes offset from the center portion. A mounting bracket is disposed in the open accommodating space of the containment member, and includes an elongated middle portion mounted on the center portion of the partition plate, and first and second end portions disposed at opposite sides of the middle portion and bent respectively relative to the middle portion so as to form first and second anchoring surfaces, respectively. A pair of socket members are retained respectively on the first and second anchoring surfaces of the mounting bracket and are adapted for mounting a respective light bulb thereon. Each of a pair of insulated conductive cord members has a first end portion connected electrically to a respective one of the socket members, and a second end portion that extends into the closed accommodating space via a respective one of the cord holes in the partition plate. A power cord member has a first connecting end adapted to be connected electrically with a power supply, and a second connecting end that extends into the closed accommodating space and that is connected electrically to the second end portions of the insulated conductive cord members.
Preferably, the lamp shade has one end extending into the open accommodating space of the containment member and mounted detachably on the partition plate. A skirt portion of the lamp shade extends outwardly from the open accommodating space. After being detached from the containment members, a plurality of the lamp shades can be stacked one over another to facilitate storage and transport of the same.
