Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a fluorescent lamp for illuminating a bank of liquid crystal panels in a liquid crystal television receiver. The present invention relates to a fluorescent lamp mounting device for mounting on a reflective umbrella.

Conventional technology Conventionally, since the liquid crystal panel in a liquid crystal television receiver does not emit light itself, it is necessary to illuminate it from the back.To do this, the light from a fluorescent lamp is reflected by a reflector and a diffuser plate is used. The back of the LCD panel was illuminated. In this case, the fluorescent lamp is lit at high frequency and high pressure, and both ends of the fluorescent lamp are fixed by insulating fixtures to the opposing side walls of a reflector whose inner surface has a reflective surface made of a metal film. It was composed.

Problems to be Solved by the Invention However, in conventional devices, fluorescent lamps are composed of glass tubes, and the diameter of the glass tubes varies widely. It is difficult to maintain a stable space between the reflective surface and the fluorescent lamp, and if the fluorescent lamp approaches the reflective surface of the reflective umbrella, the reflective surface is a metal conductor and the fluorescent lamp Since the light source is lit at high frequency and high pressure, there is a problem in that the drive efficiency decreases and the luminous flux decreases.

problem? Means for Solving the Problem The fluorescent lamp mounting device of the present invention includes a reflective umbrella having a reflective surface made of a metal film on the inner surface, and a glass tube that is made of rubber or elastomer and that constitutes a fluorescent lamp that is lit at high frequency and high pressure. U-shaped grooves V? fitted to both ends and provided on opposing side walls of the reflector. - The pusher is equipped with a pusher to be attached, and a plurality of protrusions are provided in the axial direction of the glass tube on the inner surface of the glass tube fitting hole provided in the pusher.

Function The present invention has the above configuration in which the pusher is made of rubber or elastomer, and has a plurality of protrusions in the axial direction of the glass tube on the inner surface of the hole into which the glass tube of the fluorescent lamp is fitted. By fitting each end of the glass tube of a light lamp into the U-shaped grooves provided on the opposing side walls of the reflector, all variations in the glass tube of the fluorescent lamp are absorbed, and the reflector This makes it possible to stably secure a space between the reflective surface provided on the inner surface of the fluorescent lamp and the fluorescent lamp. This eliminates the inconvenience of the metal conductor as a reflective surface coming close to the fluorescent lamp, and it is possible to completely solve the problem of lowering the driving efficiency of the fluorescent lamp and reducing the luminous flux.

Example Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show one embodiment of the present invention, and the first
In FIGS. 1 to 3, reference numeral 1 denotes a reflective umbrella, which has a reflective surface 21Li made of a metal film on the inner surface of an arc-shaped main body 2, and opposing side walls 3N, 3t) iCU-shaped grooves 4a, 4b.
It has f. Reference numeral 5 denotes a fluorescent lamp which is operated at high frequency and high pressure, and has terminals 6a, 6t) at both ends of a glass tube 5a. 7a, the pusher is a pusher made of rubber or elastomer, and is attached to the glass tube 5a of the fluorescent lamp 5.
The inner surface of the hole 8.9 has a plurality of protrusions 8a, 9a (9Δ
(not shown) is provided. And, on the outer periphery of the pushing arm aL, 7t), there is a U-shaped shape of the reflecting umbrella 1.
- The side wall 3a of the reflected sound 1 enters into the grooves 4a and 4b.
, 3b are fitted into the grooves 10.11'i. In this configuration, the pushing 71L.

Ab is connected to the glass tube 6a of the fluorescent lamp 5 in its holes 8 and 9.
When fully fitted, they are attached to both ends of the glass tube 5a, and in this state, the U-shaped pushers provided on the opposing side walls 3a, 31) of the reflector 1 are The fluorescent lamp 5 is attached to the reflector 1 by fitting into the grooves 4a and 4b and fitting into the grooves 10.11'i provided on the outer periphery of the side walls 3a and 3b. In this installed state, since the pushers 7a and ab are made of rubber or elastomer and have a protrusion 8A I 9aTh on the inner surface of the hole 8.9, the fluorescent lamp 5
The variation in the tube diameter of the glass tube 5 is completely absorbed and attached to the reflector 1, and the space of the fluorescent lamp 5 relative to the reflective surface 2a provided on the inner surface of the main body 2 of the reflector 1 is stabilized. Become.

Effects of the Invention As described above, according to the present invention, the pushers fitted to both ends of the glass tube of a fluorescent lamp are made entirely of rubber or elastomer, and the glass tube is attached to the inner surface of the hole of the pusher into which the glass tube is fitted. U-shaped projections are provided on opposite side walls of the reflector to absorb variations in the tube diameter of the glass tube. When installed in the groove, it is possible to stably secure a space for the fluorescent lamp against the reflective surface made of a metal film provided on the inner surface of the main body of the reflector, and as a result, the fluorescent lamp can be lit at high frequency and high pressure. Even if there is a metal conductor as a reflective surface, it is possible to effectively prevent a decrease in luminous flux due to a decrease in drive efficiency by ensuring a suitable space between the reflective surface and the metal conductor.
