ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a lamp and, more particularly, to a decorative lamp, which simulates the effect of an aquarium.
An aquarium-simulating lamp is shown, as shown in
FIGS. 1 and 2
, comprised of a base
10
, a rotary table
16
, an inner lamp shade
19
, an intermediate lamp shade
20
, and an outer transparent lamp shade
22
. The base
10
comprises a top coupling groove
101
. A motor (not shown) is mounted inside the base
10
. A lamp bulb
11
is provided at the top side of the base
10
. A pinion
12
is fixedly mounted on the output shaft M of the motor and disposed above the top sidewall of the base
10
. Transmission gears
13
,
14
,
15
are provided in the base
10
and meshed with one another and driven to rotate by the pinion
12
. The inner lamp shade
19
admits light, having a design of water animals, water waves, and spindrift on the outside wall thereof and a bottom coupling groove
190
. The rotary table
16
is fixedly mounted in the bottom coupling groove
190
of the inner lamp shade
19
and revolvably secured to the base
10
with a locating ring
18
by screws, comprising a plurality of hooks
160
, and a driven gear
17
meshed with the transmission gear
14
. When starting the motor, the inner lamp shade
19
is rotated with the rotary table
16
in clockwise direction on the base
10
. The intermediate lamp shade
20
admits light and is mounted on the base
10
around the inner lamp shade
19
, having a design of underwater scene on the outside wall thereof and a bottom inner gear
21
meshed with the transmission gear
13
for counter-clockwise rotation on the base
10
relative to the inner lamp shade
19
. The transparent outer lamp shade
22
is fastened to the base
10
and covered over the intermediate lamp shade
20
and the inner lamp shade
19
, having a plurality of bottom hooks
220
respectively hooked on the top coupling groove
101
of the base
10
. When starting the motor, the inner lamp shade
19
and the outer lamp shade
20
are rotated relative to each other in reversed directions, to show a motion, simulating the effect of an aquarium. This structure of aquarium-simulating lamp has numerous drawbacks as outlined hereinafter:
1. The transparent outer lampshade
22
is a simple covering that does not enlarge the image of the inner lampshade
19
and the outer lampshade
20
to produce a three-dimensional visual effect.
2. Because two rotary lampshades (the inner lampshade and the intermediate lampshade) are provided, the structure of the aquarium-simulating lamp is complicated, and much electric energy is consumed when rotating the two rotary lampshades in the reversed directions.
3. Because the aquarium-simulating lamp does not have image enlarging function, it is less attractive.
SUMMARY OF THE INVENTION
It is one object of the present invention to provide a decorative lamp, which simulates the visual effect of an aquarium. It is another object of the present invention to provide an aquarium-simulating decorative lamp, which has a simple structure. It is still another object of the present invention to provide an aquarium-simulating decorative lamp, which provides a magnified motion visual effect. According to one aspect of the present invention, the decorative lamp comprises a base holding a lamp bulb and a motor drive unit, a rotary table supported on the base around the lamp bulb and rotated by the motor drive unit, an inner lampshade fixedly mounted on the rotary table for synchronous rotation with the rotary table, the inner lamp shade having a design of underwater scene on its outside wall, and a transparent outer lampshade fixedly mounted on the base and covering over the inner lampshade, the transparent outer lampshade having a design of underwater scene on its inside wall. According to another aspect of the present invention, the transparent outer lampshade is a magnifying lampshade having ribs on its outside wall to function as convex lens means for magnifying the dimensions of the inner lampshade.
