ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fishing lamp, and more particularly, to a newly constructed fishing lamp whose light source, a LED-flash, is fabricated integrally with its lighting fixture by highly precise technique so as to achieve water tightness in structure thereby assuring its quality and prolonging its lifetime.
2. Description of the Prior Art
At the night time professional fishing operation, a conventional layout of tackles shown in
FIG. 1
is a fishing rope
200
on which a plurality of floats
800
each incorporated with a marking head
900
is extended from the ship stern to encircle a water region. Then, a string of fishing lamps
100
are suspended on the rope
200
perforating the lugs
130
provided for each fishing lamp
100
. The fishing lamps
100
together with the rope
200
drift about in the water stream so as to tempt groups of fish with lamp emitting light pretending as if that were diffused light from planktons.
FIG. 2
is a schematic view showing how a pastime night fishing is carried out using only one fishing rod and one fishing lamp.
FIG. 3A
is an exploded view of a conventional fishing lamp. As shown in
FIG. 3A
, a hollow cylindrical lamp housing is split into an upper housing
110
and a lower housing
120
. The upper housing
110
is essentially for accommodating a dry battery unit
140
with an annular shell
150
. A light source
160
and a coiled spring
170
for holding the battery unit
140
and conducting its power to the light source
160
is equipped on a pallet. The upper housing
110
is mated with the lower housing
120
by fitting it into a socket
190
formed at one end of the lower housing
120
. The assembly view of the above-mentioned components for the conventional fishing lamp is shown in FIG.
3
B.
Besides, in order to prevent entry of water and moisture, the opening at the end of the upper housing
110
is filled with a hermetic seal (for example, epoxy resin.)
With this structure, the conventional fishing lamp has been serving for professional and pastime fishing years and years effectively to a certain extent, there are several noteworthy inherent shortcomings which should be palliated, namely:
1. The fishing lamp constructed as such is too complicated so that the yield of fabrication will not be satisfactory.
2. The powerhungry lamp causes the generally applicable button type Li batteries or carbon zinc batteries to be replaced frequently from time to time, that is not only tiresome but also prone to damage the other component parts.
3. The maintenance cost is exacerbately increased by frequent battery replacement.
4. Hermetic seal at the lamp housing opening causes difficult to replace inside components.
5. Water trends to seep into the lamp housing from the socket juncture that leads to shortening the lamp life.
6. The fishing rope is easy to become kinked and the fishing line curled by the lamps overturning in the water stream and finally break to loose the fishing tackles.
Aiming at the aforesaid shortcomings, the present inventor has been endeavoring for a long time intensified research and experimentation to find out the solution and finally has come to realization of the present invention.
SUMMARY OF THE INVENTION
It is a first object of the present invention to provide a new fishing lamp capable of reducing its production cost and simplifying its fabrication process.
To achieve this object, this new fishing lamp and housing are integrately constructed so as to save use of extra separated components.
It is a second object of the present invention to provide a new fishing lamp capable of hermetically sealed.
To achieve this object, a plurality of O-rings is employed to assure the perfect watertight performance.
It is a third object of the present invention to provide a new fishing lamp which is extremely power saving yet is able to attract fish group.
To achieve this object, a durable, colorful, and power saving LED-flash is adopted as the light source, which emits diffused light as that of planktons.
It is a fourth object of the present invention to provide a new fishing lamp capable of preventing the fishing rope from kinking and the fishing line from curling by the lamps overturning in the water stream.
To achieve this object, a 360° turnable bearing including a suspension ring is provided at each end of the upper and the lower lamp housing so as to avoid above said phenomena.
