Back lighting apparatus for a lighting panel with high brightness}

The present invention relates to a lighting device for an advertising panel, more specifically, a plurality of external electrode fluorescent lamps (EEFL: Parallel Electrode Fluorescent Lamps (EEFL) in parallel to the mounting frame is installed, but the fixed frame of the fluorescent lamp By inserting and installing an electrode holder in which external electrodes are electrically coupled to each other so as to be energized, the external electrode fluorescent lamp having high brightness and stable operation characteristics can be used, and at the same time, it is easy to expand and maintain due to the enlargement of an advertising panel. A high brightness advertising panel lighting apparatus.

In general, an external electrode fluorescent lamp (EEFL) is an electrode installed externally, unlike a general fluorescent lamp, and has a high luminance because the luminance is more than 60% higher than that of a cold cathode fluorescent lamp (CCFL: Cold Cathode Flourscent Lamp). It is a fluorescent lamp that has an advantage that can be applied to applications such as a TV or TFT LCD that is required, and also can be manufactured with a relatively small outer diameter so that the lighting device can be slimmed.

Therefore, the external electrode fluorescent lamp is different from the ordinary fluorescent lamp because the electrode is installed outside to induce the discharge by flowing a current to the external electrode to emit light, at this time by minimizing the current deviation between the fluorescent lamps in a parallel connection method, Luminance can be realized.

However, the conventional advertising panel was generally an individual advertising panel using fluorescent lamps and cold cathode fluorescent lamps. In recent years, by using external electrode fluorescent lamps having excellent high brightness and operating characteristics as the lighting device of the advertising panel, Attempts have been made to produce advertising panels with clearer and more uniform brightness.

Conventionally, a plurality of external electrode fluorescent lamps having an outer diameter of about 8 mm are installed in a fixed frame of an advertising panel, and external electrodes of each fluorescent lamp are connected in parallel using a power line. By installing a plurality of lamp fixtures standing on the base plate installed on the back of the lamp fixture is coupled to the light emitting portion of the fluorescent lamp to be able to fix the fluorescent lamp.

However, such a conventional advertising panel lighting device had the following problems.

First, since the light emitting part of the fluorescent lamp is fixed to the lamp fixture installed on the base plate, a plurality of lamp fixtures are required to fix a single fluorescent lamp, thereby degrading the assembly due to the increase in the number of parts and of course, the lamp fixture emits light. There was a problem of disturbing the emission of negative light, and second, the individual sockets are coupled to the external electrodes of each fluorescent lamp, and the sockets are connected through a power line, so that the installation and disassembly of the fluorescent lamps are not easy, There was a problem that the scalability of the advertising panel was greatly reduced due to the enlargement of the advertising panel. Third, there was a problem that not only the work efficiency was deteriorated but also the manufacturing cost was increased with the increase of the assembly labor of each fluorescent lamp.

The present invention has been made to solve the above problems, an object of the present invention is to implement a brighter high-bright advertising panel by making the external electrode fluorescent lamp having a high brightness and stable operating characteristics safe and simple to use. .

On the other hand, the upper cover 50, the pressing projection 55 is formed to protrude to correspond to the guide projection 45 of the lower cover (40).

At this time, the pressing protrusion 55 is extrapolated to the guide protrusion 45, respectively, the upper cover 50 is firmly fixed to the lower cover 40 so that the insertion hole is inserted into the inner portion so that the guide protrusion 45 is pressed away Is formed.

On the other hand, the connecting portion of the electrode holder 30, which is separated into a plurality, can be molded in a male and female structure with each other.

That is, as shown in Figure 3, by forming a projection 46 in the lower portion of the front end of the lower cover 40, the insertion groove 47 corresponding to the projection 46 in the lower end, The electrode holder 30 is to be sequentially fitted.

The connection part of the electrode holder 30 is not limited to the coupling of the protrusion 46 and the insertion groove 47, and the protrusion 46 and the insertion groove 47 are formed at the front of the lower cover 40 and the upper cover 50. It may be formed in the entire rear end to be combined.

Meanwhile, the socket 60 is composed of a terminal support 62 and a terminal 65.

The terminal support 62 is formed to have a predetermined length corresponding to the number of the external electrode fluorescent lamps 21, and the terminal 65 is a portion to which the external electrodes 22 of the fluorescent lamp 21 are extrapolated and coupled. It protrudes upward at regular intervals along the longitudinal direction of 62.

In this case, the terminals 65 are formed in pairs on both sides of the terminal support 62 to be extrapolated to the external electrodes 922 of the fluorescent lamp 21.

Therefore, the socket 60 is to connect the external electrodes 22 of the plurality of fluorescent lamps 21 to the terminals 65, respectively, so that the fluorescent lamps 21 can be electrically coupled in parallel to each other.

The combination of the electrode holder 30 is as follows.

Is pressurized by the pressing protrusion 55 and is fixedly installed in the electrode holder 30.

At this time, the end of the socket 60 is connected to the ballast 70 through the power supply line (80).

Meanwhile, the light emitting part of the fluorescent lamp 12 is exposed to the outside through the through hole 56 of the electrode holder 30.

At this time, the bottom of the fixed frame 10 is coupled to the base plate (not shown) to allow the illumination of the lighting device only to the front and the billboard may be installed on the top.

5 shows another embodiment of the engagement surface of the electrode holder 30, except for the configuration of the engagement surface, which is the same as the above embodiment, and thus only the modified configuration will be described.

As shown, a protruding rib 112 of a predetermined height is formed on the side wall of the upper cover 110 along the longitudinal direction, and the protruding rib 112 is inserted into the upper end of the side wall of the lower cover 40. Insertion grooves 122 are formed along the longitudinal direction in the central portion.

Therefore, the coupling surface of the upper cover 50 and the lower cover 40 is bent, thereby preventing the electric field generated by the external electrode 22 of the fluorescent lamp 21 from being easily released to the outside.

Therefore, the present invention can arrange a plurality of external electrode fluorescent lamps 21 having high brightness and stable operation characteristics, thereby realizing a high brightness advertising panel 1 safely and simply, and a plurality of fluorescent lamps 21 By installing the integrated electrode holder 30 to securely connect with each other, the fluorescent lamps 21 are modularized so that they can be easily installed and dismantled, and the modules can be easily connected and installed to enlarge the advertising panel 1. Will be easier.
