ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a tubular light, and more particularly to a tubular light made of transparent and resilient material. The tubular light has a tubular body with two diametrically opposed notches peripherally defined to receive therein multiple light bulbs that are located in blind holes in a bottom defining each of the notches and two slits defined along opposed side face of one of the notch to receive wire. Furthermore, a resilient element is received in the tubular body so as to enable the user to form the tubular light into any form.
BACKGROUND OF THE INVENTION
Tubular light is a light that a user uses as an exterior decoration. Due to the material used to made the light being transparent and resilient, the user can use it in almost every parts of the surroundings. One example is that users often use the tubular light to decorate the roof, which increases the atmosphere especially at nighttime. A conventional tubular light is shown in
FIGS. 7 and 8
, which has a cylindrical solid core
10
with two diametrically opposed notches
11
and multiple light bulbs
20
each received in a corresponding one of blind holes
111
defined in the bottom defining each of the notches
11
and having two connecting wires
21
to electrically connect with other light bulb
20
. Each of the light bulbs
20
is received in the corresponding blind hole
111
with one blind hole
111
spaced between every two adjacent light bulbs
20
. When the light bulbs
20
are received in the blind holes
111
, two adjacent connecting wires
21
are tangled together to form a joint (not numbered) to be received in the blind hole
111
between two adjacent light bulbs
20
as shown in FIG.
8
. Afterwhich, electrical wires
22
are peripherally located on the core
10
and in parallel to the notch
11
. Then, a casino
30
made of transparent material is integrally molded outside the core
10
to surround the core
10
in an air tight manner such that the light from the light bulbs
20
are visible from outside of this tubular light.
This kind of tubular light does meet the requirements of the user. However, the electrical wires
22
are protruding out from the periphery of the core
10
, which makes the periphery of the casing
30
not smooth. Furthermore, the periphery of the casing
30
is substantially cylindrical, which makes the refraction of the light from the light bulbs
20
dull and plain.
The present invention provides an improved tubular light to overcome the above mentioned shortcomings.
SUMMARY OF THE INVENTION
The primary objective of the invention is to provide an improved tubular light having two slits defined along the notches of the hollow core to receive the electrical wires, such that when the casing is molded outside the hollow core, the outer periphery of the casing is smooth.
Another objective of the invention is to provide a polygonal casing integrally formed outside the hollow core to increase the refraction of the light from the light bulbs.
Still, another objective of the invention is to provide a tubular light with a resilient element embedded in the tubular body so as to enable the user to form the tubular light into any form required.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
