Description

Fluorescent lamp reflector and fluorescent lighting device using the reflector {REFLECTING SHADE OF FLUORESCENT LAMP AND DEVICE OF FLUORESCENT LAMP USING BY THE REFLECTING SHADE}

The present invention relates to a fluorescent lamp reflector and a fluorescent lighting device using the reflector, in particular high reflectance efficiency, good assembly, easy to repair, simple wiring structure and fluorescent lighting device using the reflector It is about.

In general, the billboard is formed in the form of a display board made of translucent acrylic plate on the front or front and rear surfaces of the housing, a plurality of fluorescent lighting fixtures are installed in the housing.

The fluorescent lighting apparatus includes a support, two fluorescent lamp sockets provided on both sides of the support and connected to and supported by pin terminals of the fluorescent lamp, and a reflection shade provided on the bottom of the support.

However, in the conventional fluorescent lighting device as described above, as shown in Fig. 9, the reflector 9 is approximately obliquely downward from both ends of the flat plate 91 in the center and in the width direction of the flat plate 91. Since the two swash plate portions 92 and 92 extend respectively, the light irradiated onto the flat plate 91 and the swash plate portions 92 is almost at the A of the advertisement surface 96 located in front of the fluorescent lamp 95. Because it is reflected intensively to the displayed areas, the closer the advertising surface 96 is to the fluorescent lamp 95, the brighter the other part is, and the remaining part is rapidly darkened. Therefore, streaks occur according to the position of the advertisement surface, so low illuminance is weak and illumination intensity is deteriorated so that the illumination quality is degraded. In addition, since the reflector 9 is fixed to the support by the fastening means, the installation and detachment of the reflector 9 is difficult, which makes the repair of the fluorescent lighting device difficult.

In addition, in the general fluorescent lighting device, a ballast and a start socket for supplying power to the fluorescent lamp are installed on the upper surface of the support, and wires are exposed with dizzying exposure of the wires on the upper and lower sides of the support to make maintenance of the fluorescent lighting device more difficult. do. In addition, when the fluorescent lamp socket is coupled to both sides of the support, the fastening device is used to adversely affect the maintenance of the fluorescent lighting device. In addition, when a plurality of rows of fluorescent lighting devices are installed on both sides of the billboard, the outside of the fluorescent lamp socket protrudes, and there is no choice but to create a gap between the rows. Therefore, a shadow is formed on the area of the billboard corresponding to the gap. There is also a problem that the lighting quality is degraded.

On the other hand, in the case of the advertising signboard, in order to install the fluorescent lighting device inside, instead of using a fluorescent lamp support separately, the support rod installed inside the housing is often fixed as a fluorescent lamp support to fix the general reflector as described above. Not only does the quality deteriorate, but the wires are more cluttered than in the case described above, and the maintenance of the fluorescent lighting device becomes more difficult.

In addition, in the case of the reflection shade fixed to the support rod installed inside the signboard housing, in order to improve the lighting quality, a reflection shade provided with a transparent support film into which a fluorescent lamp is inserted at the bottom of the center portion of the reflection shade has been proposed, but the reflection shade is not suitable for installation and replacement of the fluorescent lamp. Not only is it difficult to reduce the roughness by the transparent support film, and also when the dust or foreign matter attached to the transparent support film, the roughness is further lowered. In addition, since the fluorescent lamp is supported by the support film, the rear side of the fluorescent lamp is in close contact with the central portion of the reflection shade, so that the reflection efficiency is rather lowered.

The present invention is devised to solve the above-mentioned problems, and provides a high reflectance efficiency, good assemblability, easy maintenance, and a simple fluorescent lamp reflector and a fluorescent lighting device using the reflector. For the purpose.
