Description

Reflecting shade assembly for fluorescent lamp

The present invention relates to a reflective lamp assembly of a fluorescent lamp.

As shown in FIG. 7, the fluorescent lamp reflector assembly 51 includes a casing 53 on which the fluorescent lamp 75 is mounted, and is embedded in a ceiling 91 of the room. A pair of fluorescent lamps 75 are mounted on the bottom of the casing 53, and a ballast 71 is also provided in the center region thereof. This configuration makes it possible to easily repair or replace the ballast 71 in a state where the reflecting lamp assembly 51 is embedded in the ceiling 91.

On the other hand, the visual exposure of the ballast 71 is shielded by a reflective cover 61, which is disposed in front of it and detachable to the casing 53. The reflective cover 61 has a hat-shaped cross section, and forms a receiving space 55 between the bottom surface of the casing 53. The ballast 71 is accommodated in this accommodating space 55, whereby the appearance quality can be improved. Reflective cover 61 serves to reflect the light emitted from the fluorescent lamp 75 to the room, in addition to this purpose.

By the way, in the conventional reflector assembly 51, such as a glimmer, the size of the accommodating space 55 formed by the casing 53 and the reflective cover 61 is constant, whereby the ballast 71 has to be replaced. In this case, there is a problem in that the ballasts 71 having different sizes cannot be interchangeably applied to various models. In particular, the reflective cover 61 can increase the amount of reflection of fluorescent light by increasing the area of both inclined portions 63 and 65 as much as possible, thereby improving the degree of illumination of the room. In the case where the inclined portions 63 and 65 are curved in a planar to inward direction, the area of the accommodation space provided between the bottom surface of the casing 53 is relatively narrowed, making it difficult to install the stabilizer 71. . Therefore, if the space capable of accommodating the stabilizer 71 can be widened, the stabilizer 71 of various sizes can be installed interchangeably, and since the reflective area of the reflective cover 61 can be widened as much as possible, It would be desirable to improve the degree of illumination of the room.

Accordingly, it is an object of the present invention to provide a reflector assembly of a fluorescent lamp that can easily mount a ballast of various sizes by providing a relatively wide ballast space in consideration of such a conventional problem.

Another object of the present invention is to provide a reflector assembly of a fluorescent lamp that can maximize the reflecting area of the reflecting cover, thereby improving the illumination of the room.

As can be seen from these figures, the fluorescent lamp assembly 1 includes a rectangular casing 3, two pairs of sockets 9, stabilizers 21 and 22, and a reflecting cover 11.

The casing 3 is provided in a substantially rectangular plate bottom plate 4 and a pair of long side walls 5 and bottom plate 4 provided on both sides of the bottom plate 4 in the longitudinal direction of the bottom plate 4 and facing each other. It has a pair of short side walls 6 which are mutually standing up on both side edges in the transverse direction. These bottom plates 4, the long side walls 5 and the short side walls 6 form the fluorescent lamp receiving portion 7 in the casing 3.

On the inner wall surface of each short side wall 6, a pair of socket 9 is provided in parallel at predetermined intervals. These sockets 9 are arranged to face each other with the sockets 9 provided on the other end side wall 6. To this end, a socket position groove (not shown) is formed in the inner wall surface of the short side wall 6. The socket fixing hook 10 protrudes from the rear surface of the socket 9 to be fixed to the socket position groove. The terminals of the fluorescent lamps 40 are accommodated in the sockets 9 opposed to each other in a fixed position, whereby a pair of fluorescent lamps 40 can be mounted in the fluorescent lamp receiving portion 7 in parallel.

Stabilizers 21 and 22 are attached to the bottom plate 4 in the center region between the pair of fluorescent lamps 40. The reflective cover 11 is detachably coupled to the front of the ballasts 21 and 22. In order to couple the reflective cover 11, the bottom plate 4 is provided with a pair of engaging projections 27 that face each other. The pair of locking projections 27 are provided in plural places between the fluorescent lamps 40 on the bottom plate 4 at predetermined intervals along the longitudinal direction thereof. Each locking projection 27 can be formed by cutting the bottom plate 4 and simply bending it upward, and each end portion is also bent toward the opposite locking projection 27.

On the other hand, the reflective cover 11 has a substantially rectangular plate shape, the center region of which is bent along the longitudinal direction to form a hatshade as a whole, and inclined portions 13 are formed on opposite sides of each other. In each of the inclined portions 13, the bent portions 62 provided in the inclined portions 63 and 65 of the reflective cover 61 described with reference to FIG. 7 are removed, and the reflection area thereof is formed to be wide. Therefore, the amount of reflection of the light emitted from the fluorescent lamp 40 is increased. The longitudinal edge of each inclined portion 13 is formed by a bite edge 15 engaged with the engaging projection 27 of the bottom plate 4. The inclined portion 13 forms a reflecting surface that reflects light rays emitted from the fluorescent lamp 40 into the room.

The reflection cover 11 is further provided with an operation portion 31 recessed with respect to the plate surface on both inclined portions 13. The operation part 31 maintains an angle between the bottom plate 4 and the angle between the bottom plate 4 and the inclined part 13 and is large enough to accommodate a finger. In this manner, the operator's thumb and middle finger are accommodated from both sides, respectively, and when the pressure is applied inwardly in this state, the reflective cover 11 is elastically deformed. As a result, both of the engaging edges 15 of the reflective cover 11 can be fitted into the engaging projections 27 so as to be easily engaged with each other, while releasing the engaging projections 27 and the engaging edges 15 engaged with each other. You can.

On the other hand, when the reflective cover 11 is coupled to the bottom plate 4 of the casing 3, a predetermined accommodation space is formed therebetween. The ballasts 21 and 22 are housed in this accommodation space. In order to accommodate the ballasts 21 and 22, the bottom plate 4 is provided with a ballast mounting groove 41 recessed upward with respect to the bottom surface thereof. The stabilizer mounting groove 41 has a bottom surface corresponding to a lengthwise section in the transverse direction with respect to the longitudinal direction of the reflective cover 11 is recessed upward with respect to the reference surface, and extends toward both short side walls 5. . Therefore, the ballasts 21 and 22 having different lengths can be interchangeably accommodated in the ballast mounting groove portion 41.

In addition, the receiving space formed by the reflection shade assembly 1 by the ballast mounting groove formed on the bottom plate is the bottom plate 54 and the reflection cover 61 of the reflection shade assembly 51 described with reference to FIG. 5. The space is much wider than the receiving space that is formed. Therefore, the ballasts 21 and 22 of various models having a height as well as a length can be interchangeably mounted therein.

In order to assemble the reflector assembly 1 of this fluorescent lamp having such a configuration, first, the ballasts 21 and 22 suitable for the purpose of use are attached to the bottom plate 4 of the casing 3. The ballasts 21 and 22 have a plurality of fixed ribs 24 protruding laterally from the bottom surface thereof. Therefore, in order to mount the ballasts 21 and 22, the ballasts 21 and 22 are arranged in the ballast mounting groove 41 formed in the bottom plate 4 of the casing 3, and then fastening members such as screws 23 and the like. By using the fastening rib 24 and the bottom plate 4 integrally integrally, it can be simply completed.

Meanwhile, at the same time or sequentially, the sockets 9 are respectively coupled to both side end walls 6 of the casing. Then, the reflection cover 11 is coupled to the front of the ballast (21, 22). As described above, the coupling of the reflective cover 11 is a block of the bottom plate 4 in a state where the operation unit 31 formed on the inclined portion 13 is gripped with a finger and pressed inward to elastically deform inwardly. It is completed by simply accommodating in the 27. Then, the reflection cover 11 is restored by its elastic force, and the outward departure is prevented by engaging the engagement edge portion 15 and the engaging projection 27 mutually.

After the reflection cover 11 is coupled, the terminals of the fluorescent lamp 40 are coupled to the sockets 9 facing each other, whereby the assembly of the reflection shade assembly 1 is completed. After that, the suspended reflector assembly 1, which has been assembled, is suspended on the suspension device 61 installed on the ceiling 91 and the wiring is connected, so that the office or exhibition hall can be illuminated.
