Lighting fitting

A lighting fitting for an incandescent lighting arrangement with a pair of incandescent bulbs, includes a lampshade body and a mounting bracket. The lampshade body is formed from molding plastics, and has an upper wall that defines a central through hole, and a skirt portion that extends downwardly and divergently from the periphery defining the upper wall. The mounting bracket includes an elongated middle portion which is formed with a mounting hole aligned with the through hole, and which has a distal wide surface and a proximate wide surface relative to the upper wall, and first and second end portions which are in line with and disposed at opposite ends of the middle portion. The first and second end portions are bent to an acute angle relative to and toward the distal wide surface of the middle portion along two parallel lines which incline at a predetermined angle relative to a vertical line that crosses a longitudinal direction of the middle portion so as to form first and second anchoring surfaces. The first and second anchoring surfaces respectively face two opposite inner surfaces of the skirt portion. The incandescent bulbs respectively have a bulb base fixed on the respective anchoring surface.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The invention relates to a lighting fitting, more particularly to a 
lighting fitting for an incandescent lighting arrangement which has a pair 
of incandescent bulbs. 
2. Description of the Related Art 
A conventional lighting fitting includes a lampshade body of molding 
plastics, amounting bracket, a socket member, a pair of insulated 
conductive cord members, a containment member, a power cord member, and an 
incandescent bulb. The incandescent bulb has a bulb body and a bulb base. 
The lampshade body has an upper wall with a through hole formed 
therethrough, and a skirt portion which extends downwardly and divergently 
from the periphery confining the upper wall. The mounting bracket is fixed 
to the upper wall, and has a mounting hole aligned with the through hole 
of the upper wall, and a mounting face distal relative to the upper wall. 
The socket member has a shell portion to receive the bulb base, and a seat 
portion which extends from the shell portion in an axial direction and 
which is disposed perpendicularly to abut against the mounting face of the 
bracket member. The insulated conductive cord members have first ends 
connected conductively to the seat portion of the bulb body, and second 
ends that extend through the mounting hole of the bracket member and the 
through hole of the upper wall to form a first contact terminal. The 
second ends of the insulated cord members are disposed outwardly and 
upwardly relative to the lampshade body. The containment member is capable 
of housing electrical components associated with the supply of electricity 
to the incandescent lighting arrangement, and includes a circumferential 
wall superimposed upon the upper wall of the lampshade body when the 
containment member is coupled with the lampshade body. The power cord 
member is adapted to be connected to a power supply and is led downwardly 
and outwardly of the circumferential wall of the containment member to 
form a second contact terminal for coupling conductively with the first 
contact terminal. 
Note that the incandescent bulb extends downwardly and vertically relative 
to the bracket member in the conventional lighting fitting. The lighting 
effect provided thereby is inferior to a halogen lamp which has the same 
wattage as the incandescent bulb, thereby resulting in discomfort to a 
user who is accustomed to the lighting arrangement of the halogen lamp. 
SUMMARY OF THE INVENTION 
Therefore, the object of this invention is to provide a lighting fitting 
for an incandescent lighting arrangement that includes a pair of 
incandescent bulbs and that can provide lighting arrangement comparable to 
that of a halogen lamp which has the same wattage as the incandescent 
bulbs. 
Accordingly, the lighting fitting of this invention is adapted for an 
incandescent lighting arrangement with a pair of incandescent bulbs, and 
includes a lampshade body, a mounting bracket, a pair of socket members, a 
pair of insulated conductive cord members, a containment member, and a 
power cord member. The lampshade body is formed from molding plastics, and 
has an upper wall that defines a through hole in a center thereof, and a 
skirt portion that extends downwardly and divergently from the periphery 
defining the upper wall. The mounting bracket includes an elongated middle 
portion which is formed with a mounting hole that is aligned with the 
through hole of the upper wall and which has a distal wide surface and a 
proximate wide surface relative to the upper wall, and first and second 
end portions which are in line with and disposed at opposite ends of the 
middle portion. The first and second end portions are bent to an acute 
angle relative to and toward the distal wide surface of the middle portion 
along two parallel lines which incline at a predetermined angle relative 
to a vertical line that crosses a longitudinal direction of the middle 
portion so as to form first and second anchoring surfaces. The first and 
second anchoring surfaces respectively face two opposite inner surfaces of 
the skirt portion. Each of the socket members has a shell portion adapted 
to receive the bulb base of one of the incandescent bulbs, and a seat 
portion which extend from the shell portion in an axial direction and 
which is disposed to abut against one of the first and second anchoring 
surfaces with the axial direction normal relative to the respective inner 
surface of the skirt portion. Each of the insulated conductive cord 
members has one end portion connected conductively to the seat portion of 
the socket member, and the other end portion led through the mounting hole 
of the middle portion and the through hole of the upper wall to form a 
first contact terminal. The first contact terminal is disposed upwardly 
and outwardly relative to the lampshade body. The containment member is 
capable of housing electrical components that are associated with the 
supply of electricity to the incandescent lighting arrangement, and 
includes an upper body which has a circumferential wall and an annular 
portion extending downwardly from the circumferential wall and of a 
dimension to shield the upper wall when the containment member is coupled 
with the upper wall of the lampshade body. The power cord member is 
adapted to be connected to a power supply and is led downwardly and 
outwardly of the upper body and into the annular portion to form a second 
contact terminal which is coupled electrically with the first contact 
terminal.
