ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a stand lamp assembly, more particularly to a stand lamp assembly that includes main and auxiliary lamp units.
2. Description of the Related Art
Referring to
FIGS. 1 and 2
, a conventional stand lamp assembly
900
is shown to comprise a power control circuit
91
, a stand base
92
, a hollow upright stand body
93
, an auxiliary lamp unit
94
, a main lamp unit
95
, an annular skirt member
96
, and a lampshade
97
. The power control circuit
91
includes a power cord
911
and a wire unit
912
that extends outwardly from a center hole
921
in the stand base
92
to connect with the main lamp unit
95
. The stand body
93
has a lower portion
931
engaged threadedly to the center hole
921
in the stand base
92
. A power switch
933
is connected to the control circuit
91
so as to control activation of the main lamp unit
95
. The auxiliary lamp unit
94
includes an upright frame member
943
, a tubular sleeve
944
, a night lamp
942
, and a light sensor
941
. The upright frame member
943
has a lower section engaged to an upper portion of the stand body
93
by means of a connector
934
, a left side formed with a hollow post
9431
for extension of the wire unit
912
therethrough, and a right side formed with a night lamp socket
9432
. The tubular sleeve
944
is sleeved on the upright frame member
943
. The night lamp
942
is mounted on the night lamp socket
9432
of the frame member
943
. The light sensor
941
is connected to the night lamp
942
and the power control circuit
91
so as to control activation of the night lamp
942
in accordance with ambient light conditions. The main lamp unit
95
includes a pair of main lamp sockets
954
, a pair of main lamps
957
, a positioning seat
952
, and a lamp socket holder
953
. Each main lamp
957
is mounted on a respective one of the main lamp sockets
954
. The positioning seat
952
is formed with an upper plate portion
9521
seated on the upper end of the tubular sleeve
944
, and a retaining post portion
9522
extending downwardly from the upper plate portion
9521
and insertingly retained in the tubular sleeve
944
. The lamp socket holder
953
is mounted on the upper plate portion
9521
. The wire unit
912
extends through the positioning seat
952
and the lamp socket holder
953
so as to connect with the main lamp sockets
954
. The main lamp sockets
954
are retained in anchoring end portions
9531
of the lamp socket holder
953
. The annular skirt member
96
is disposed to surround the upper plate portion
9521
of the positioning seat
952
. The lampshade
97
is seated on the upper plate portion
9521
of the positioning seat
952
, and is disposed to surround the lamp socket holder
953
, thereby surrounding the main lamps
957
.
A drawback of the conventional stand lamp assembly resides in that when the night lamp
942
is damaged or malfunctions, it is very difficult to replace the night lamp
942
since the tubular sleeve
944
has no opening in its peripheral wall. Since the tubular sleeve
944
has no opening, the main lamp unit
95
has to be disassembled first before the night lamp
942
can be removed.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a stand lamp assembly that can facilitate replacement of a night lamp of an auxiliary lamp unit without disassembling the main lamp unit.
According to the present invention, a stand lamp assembly includes a stand frame unit, and auxiliary and main lamp units. The auxiliary lamp unit includes a night lamp disposed removably on a night lamp socket, a light sensor to control activation of the night lamp in accordance with ambient light conditions, and a sleeve disposed around the night lamp and having a rotatable cover body that can be opened to permit removal of the night lamp via an opening in the sleeve.
