Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a fluorescent lamp illuminator that is placed in front of the upper surface of the upper frame of an ornamental fish tank to illuminate the inside of the tank.

[Conventional technology]

Usually, this kind of aquarium lighting fixture is, as shown in FIG.
The inside of the water tank 1 is illuminated by a fluorescent lamp 4 which is placed in front of the upper surface of the upper frame 2 in the water tank 1 and provided inside a plastic cover 3. This lighting equipment cover 3 has an upper frame 2
It is necessary to correctly dispose the cover 3 relative to the upper surface of the cover 3, but conventionally, as a means for this, the total length L1 of the cover 3 is set to
Is slightly larger than the length L2 of the cover 3 so that both side walls 5 of the cover 3 project outward from the side surface 2a of the upper frame 2 and the locking sides 6 project from the lower ends of the side walls 5 of the cover. The side 6 is engaged with the outer side surfaces 2a of the upper frame 2 so that the lighting equipment cover 3 does not move in the left-right direction on the upper surface of the upper frame 2.

[Issues to be solved by the device]

As described above, since the conventional lighting device has the engaging sides 6 for the both side surfaces of the aquarium upper frame 2 only at the lower ends of the left and right side walls 5 of the cover, the upper surface of the upper frame 2 of the lighting device slips down in the left-right direction. Can be prevented, but there is a problem in that it cannot prevent falling off in the front direction.

In addition, inside the cover 3 of the lighting fixture, pores 8 are formed in the front inclined wall 7.
Is opened to release the heat generation temperature of the fluorescent lamp 4 inside the cover 3 to the outside, but since the inside of the cover 3 is always heated by the heat generation of the fluorescent lamp 4,
During the use period, the central portion of the cover 3 is curved and deformed so as to bulge upward. As a result, the central lower edge 9a of the front wall 9 of the cover, which comes into contact with the upper surface of the front side of the water tank upper frame 2, warps upward to form a gap of about 1 to 3 mm with the upper surface of the front side of the upper frame 2, and from this gap The light of the fluorescent lamp 4 leaks to the outside of the front surface of the cover 3 and has a defect that the product has an unpleasant appearance because it has a character as an ornamental product.

[Means for Solving the Problems]

The present invention solves the above-mentioned problems of the conventional aquarium luminaire, and the luminaire does not slide down not only in the left-right direction but also in the front on the upper surface of the aquarium upper frame, and extends for a long period of time. It is an object of the present invention to provide a luminaire that can prevent deformation of the luminaire cover that may cause light to leak to the outside due to the heat generation temperature of the fluorescent lamp even in use.

As a concrete means for this purpose, the present invention is such that the lower end is recessed in the upper surface of the aquarium upper frame inside the front wall of the cover of the fluorescent lamp lighting fixture placed in front of the upper frame of the aquarium fish tank. It is characterized in that a front locking wall projecting downward so as to be fitted to the inner periphery of the front side of the glass lid shelf is provided in parallel along the front wall of the cover.

The problem-solving means aimed at by the present invention is basically achieved by providing the above-mentioned front locking wall inside the front wall of the cover. It is a strength to have a structure in which side-face locking walls projecting downward so as to be fitted to the inner circumferences of both left and right sides of the glass lid receiving rack are integrally projected from both ends of the front-side locking wall. It is preferable from the standpoint of physical aspect.

[Action]

In this invention, the front cover wall projecting downward is provided inside the cover front wall so that the lower end is fitted to the inner circumference of the front side of the glass lid receiving shelf of the water tank upper frame. When it is properly placed on the upper surface of the upper frame, the lower end of the front locking wall is dropped onto the front side of the glass lid receiving shelf which is recessed one step lower than the upper surface of the upper frame. The lower end front surface of the stop wall is engaged with the inner peripheral surface of the falling wall which is in contact with the front side of the receiving shelf. Therefore, the lower edge of the front wall of the cover that forms the outer periphery of the instrument cover is merely placed on the upper surface of the upper frame, but the lower edge of the front locking wall provided inside is the inner surface of the falling wall for receiving shelves. Therefore, even if the device cover is slid forward along the upper surface of the upper frame, the front locking wall prevents the forward movement.

Further, since the front locking wall is provided parallel to the front wall of the cover, the instrument cover is lifted when the lower end of the locking wall is dropped onto the front side of the receiving shelf as described above. If you try to slide it in the left-right direction along the upper surface of the frame, the lower parts of both ends of the locking wall will be locked to the inner peripheral surfaces of the falling walls on both sides of the receiving shelf, and the tool cover will move in the left-right direction. Will also be blocked.

The movement of the instrument cover in the left-right direction can be substantially prevented by the lower portions of both end edges of the front locking wall as described above. When the side locking walls are integrally extended at an angle of, the lower end edges of these side locking walls are locked to the inner peripheral surfaces of the falling walls on both sides of the receiving rack, and The movement to the left and right is more reliably prevented.
