The present invention mainly relates to an underwater fluorescent lamp installed in the water in the aquarium, and more particularly to a waterproof device of the underwater fluorescent lamp designed so that the fluorescent lamp is not short-circuited by the water.

In general, when the fluorescent lamp is installed in the water and turned off, it is effectively shielded from the outside (foreign material, moisture, etc.), so the life can be extended.

Therefore, in recent years, in the case of using as a lighting lamp of the aquarium, a means to prepare a case submerged in water and to install a fluorescent lamp is used, but in this case, it becomes bulky, and it is inconvenient and troublesome to replace and repair the fluorescent lamp It became.

The present invention is to provide a waterproof device, such as underwater fluorescent lamps that can narrow the volume in consideration of the conventional problems as described above, excellent waterproof effect and easy disassembly and assembly.

In order to achieve this purpose, a transparent glass tube into which fluorescent lamps are inserted is provided, and both sides of the transparent glass tube are provided with a packing, a glass tube support, and a binding hole, so as to be completely waterproof with the outside. In more detail based on the following.

In the drawing, reference numeral 1 denotes a transparent glass tube, and the transparent glass tube 1 is one having a size larger than the diameter or length of the fluorescent lamp 2, and the fluorescent lamp 2 is inserted into the glass tube 1. The reflection plate 1a is inserted into one side of the inner surface of the transparent glass tube 1 together with the fluorescent lamp 2. The reflecting plate 1a is used without being fixed inside the transparent glass tube 1 and is sandwiched between the inner surface of the transparent glass tube 1 and the fluorescent lamp 2, and is slightly reflected when transporting or installing an underwater fluorescent lamp. (1a) Although the movement occurs, once the underwater fluorescent light is installed in the aquarium where it is mainly used, the underwater fluorescent light does not move unless it is moved arbitrarily thereafter, so that one surface of the reflector 1a is transparent or the fluorescent lamp 1 (2) Since it stays in contact with the outer circumferential surface, there is no problem in performing the function of reflecting fluorescent light in one direction.

On the other hand, both ends of the transparent glass tube (1) is inserted into the insertion hole (3b) of the glass tube support (3) (3 ') having a female thread portion (3a) on the inner surface of the glass tube support (3) (3') The packing (4) (4 ') is to be inserted into the inner end of each so that the surface of the transparent glass tube (1) and the packing (4) (4') is installed to be in close contact.

And the male screw portion (3a) of the glass tube support (3) (3 ') to the male screw portion (5b) of the fastener (5) (5') having a tube insertion hole (5a) to be fastened but the binder (5) The fastening portion 6 having the wire through hole 6a is formed to protrude from the binding hole 5 on the side through which the electric wire 9 side for supplying electricity to the fluorescent lamp 2 is passed. The fastening part 6 is configured to fasten the wire cap 8 into which the wire packing 7 is inserted, so that the wire through hole 6a is sealed by the wire packing 7.

In the figure, reference numeral 10 denotes a support having a suction plate 10a, which is used to support an underwater fluorescent lamp on the adherend.

Since the present invention configured as described above has the transparent glass tube 1 covered on the outside of the fluorescent lamp 2, the fluorescent lamp light is faithfully transmitted to the outside as well as the overall waterproofing so that the lighting effect is not degraded at all. At this time, the reflector 1a serves to illuminate the light in one direction. When the fluorescent lamp is installed to be illuminated upward, the reflector 1a is placed in contact with the inner surface of the transparent glass tube 1 and has a reflective function. On the other hand, when the fluorescent lamp is installed to illuminate downward, the reflective plate 1a is placed on the outer circumferential surface of the fluorescent lamp 2 so as to perform a reflective function, even though the reflective plate 1a depends on the installation state of the underwater fluorescent lamp. ) Is a slight movement, but since it is used in a fixed state if it is normally installed, it can be used without causing any problems in performing the reflex function.

And the present invention is there is a glass tube support (3) (3 ') for supporting both ends of the tube on both sides of the transparent glass plate (1) at the same time both ends of the glass tube support (3) (3') insertion The transparent glass tube 1 not only has a firm holding force but also is supported at both ends of the transparent glass tube 1 because it is inserted into and supported inside the tube insertion hole 5a of the fastener 5 and 5 'through the ball 3b. The glass tube support (3) (by the packing (4) and 4 ') is blocked by the outside while being coupled to the support (3) (3') and the fitting (5) (5 '). Since the gap of the insertion hole 3b of 3 ') is completely enclosed, the waterproof hole which prevents water from penetrating into the part which opened in both sides of the transparent glass tube 1 is aimed at.

In addition, when the wire 9 connected to the fluorescent lamp 2 passes through the one-side binding port 5, the fastening portion (with the wire packing 7 inserted into the wire 9) is inserted into the wire cap 8. 6) Since the wire packing (7), which receives the fastening force of the wire cap (8), completely closes the wire through hole (6a), this part is also water resistant to prevent water from entering. Done.

As described in the above description, the present invention has a structure in which water does not penetrate into the transparent glass tube (1) in which the fluorescent lamp (2), which is weak to moisture, is completely waterproof, as well as the size of the fluorescent lamp and a slightly larger dimension. The fluorescent glass 2 is inserted into the transparent glass tube 1 having a structure such that the size and volume of the entire underwater fluorescent lamp can be reduced more than before, thereby simplifying handling and reducing costs. In addition to dissipating and disassembling the binder (5) (5 ') and disassembling the glass tube support (3) (3'), the fluorescent lamp (2) can be removed. And the inspection can be carried out more quickly and easily.

Claims (2)

Both ends of the transparent glass tube 1 into which a known fluorescent lamp 2 is inserted are inserted into the insertion hole 3b of the glass tube support 3 and 3 ', and the packing 4 is inserted into the insertion hole 3b. (4 ') is fitted so as to be in close contact with the outer peripheral surface of the transparent glass tube (1) while the male thread portion (5b) of the fastener (5) (5') to the female thread portion (3a) of the glass tube support (3) ) So that both ends of the transparent glass tube (1) are inserted into the tube insertion hole (5a) of the binding port (5) (5 ') to be sealed to seal the waterproof device for underwater fluorescent lamps. The fastening part 6 according to claim 1, wherein the fastening part 6 having a wire through hole 6a through which the electric wire 9 connected to the fluorescent lamp 2 passes is formed to protrude in the center of the one end fastening hole 5. A waterproofing device for underwater fluorescent lamps such that the wire packing (7) fitted to the wire (9) by the fastening force of the wire cap (8) fastened to the wire) to seal the wire through hole (6a).
