ABSTRACT:
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates to a decorative lamp assembly and, more particularly, to such a decorative lamp assembly, which causes colored tiny plastic balls to move up and down with air bubbles in an enclosed ornamental tube when turned on to emit light.
FIGS. from
1
through
3
show a decorative lamp assembly
9
according to the prior art. This structure of decorative lamp assembly
9
is comprised of an adapter
91
, a bulb
911
, lampshade
92
, and an ornamental tube
93
. The adapter
91
has a socket side adapted to receive the bulb
911
, and a plug side adapted to receive power supply from an electric outlet. The lampshade
92
is comprised of an upper shell
921
and a bottom shell
922
. The ornamental tube
93
is an enclosed tube of glass material, having a porous bottom stuffing layer
931
formed of sodium silicate (NaSiO
3
) and silica (SiO
2
), and an upper stuffing material of dichloromethane (CH
2
Cl
2
)
90
. During the fabrication of the ornamental tube
93
, sodium silicate (NaSiO
3
) and silica (SiO
2
) are put in the tube and heated to about 30°~35° C. When cooled down, sodium silicate is condensed and bonded to the inside wall of the tube. After formation of the porous bottom stuffing layer
931
, dichloromethane
90
is put in the tube with a space left above dichloromethane
90
, and then the tube is sealed after exhaust of air. The lampshade
92
is fastened to the adapter
91
around the bulb
911
. The ornamental tube
93
is fastened to the top side of the upper shell
921
of the lampshade
92
, keeping the bottom end suspended above the bulb
911
. When turning on the bulb
911
, heat energy is transmitted from the bulb
911
through the porous bottom stuffing layer
931
to the upper stuffing material of dichloromethane
90
to boil dichloromethane
90
into air bubbles
900
. At the same time, light rays pass from the bulb
911
through the porous bottom stuffing layer
931
and the bubbles
900
, producing a lighting effect. The visual effect produced during working of the decorative lamp assembly
9
is less attractive.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a decorative lamp assembly, which produces a fantastic visual effect when operated. According to the present invention, tiny plastic balls of different colors are put in the space inside the ornamental tube above the upper stuffing material of dichloromethane. When boiling the upper stuffing material of dichloromethane into air bubbles, the colored tiny plastic balls are forced to move up and down with the air bubbles.
