ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a lamp assembly that has a control member connected to a pull switch and a chain. The control member is activated either by pulling the chain or touch the chain.
BACKGROUND OF THE INVENTION
A conventional lamp assembly is shown in
FIGS. 1 and 2
and generally includes a base
1
with a post
11
extending therefrom and a socket
21
is connected to a top of the post
11
. An electrical cable
5
extends through the post
11
and is connected to a pull switch
3
and a bulb frame
22
respectively by two wires
51
and
52
. A connection wire
6
is connected between the bulb frame
22
and the pull switch
3
. A chain
31
is connected to the pull switch
3
and extends through an aperture
24
of the socket
21
. The bulb frame
22
has an insertion portion
221
which is inserted in the socket
21
and a flange
222
extends from the bulb frame
22
and is rested on a top edge of the socket
21
. A positioning member
23
has an inner threaded periphery
232
which is threadedly connected to an outer threaded periphery of the socket
21
so as to position the bulb frame
22
. A bulb
4
is then connected to the bulb frame
22
.
The conventional pull switch is activated by pulling the chain
31
and the interior parts of the switch are easily to be worn out due to frequent operations and the chain
31
could be broken.
SUMMARY OF THE INVENTION
The present invention relates to a lamp assembly which comprises a base with a post extending from the base and a socket is connected to a top of the post so as to be connected to a bulb frame thereto. An aperture is defined through the socket in which a control member and a pull switch are respectively received. An electrical cable is connected to the control member and a first connection wire is connected between the control member and the bulb frame. A second connection wire is connected between the pull switch and the bulb frame.
A chain is connected to the pull switch and extends through the aperture of the socket. The control member is activated by either pulling the chain or touching the chain.
The primary object of the present invention is to provide a lamp assembly wherein the bulb of the lamp assembly is controlled by a control member which can be activated by either pulling the chain or touching the chain.
