Conventionally used billboards using commercial voltage, the form of a box is provided with a front plate composed of a translucent acrylic plate on the front, and is configured by installing a plurality of fluorescent lamps connected to the ballast in the inner rear of the box. When commercial power is supplied to the ballast, the fluorescent lamp is turned on, and the letters or pictures displayed on the front are distinguished from the surroundings by the light emitted from the fluorescent lamp.

However, the fluorescent lamps used in the conventional billboards, such as the rated voltage is 220V, the operating frequency is 60Hz, so that the power consumption is 20W, or 40W or more, power consumption and cost problems caused by long time use. In addition, when the size of the characters or pictures displayed on the billboard is increased, the difficulty due to the production of the billboard is increased and there is a difficult problem in the installation of the billboard.

Another problem of the conventional billboard is due to the luminance decrease or failure of the fluorescent lamp with long time use. In other words, the general fluorescent lamp is degraded as the use time increases, the brightness is required to disassemble the billboard to replace the fluorescent lamp takes a lot of time and must be performed by a skilled worker. Therefore, even when the luminance of the fluorescent lamp is lowered or broken, it is often left untouched, which makes it difficult to achieve the purpose of the billboard.

In order to solve the above problems, the applicant has filed a patent application No. 2002-61170 "advertising board using a custom fluorescent lamp". The tubular fluorescent lamp billboard can be manufactured in a smaller, thinner form than a billboard using a conventional fluorescent lamp, it is also possible to provide a billboard with easy removal of the fluorescent lamp and significantly reduced power consumption.

First, referring to FIGS. 1 to 5, a fixing structure of a tubular fluorescent lamp used in an advertisement board previously filed by the applicant will be described. FIG. 1 shows a fluorescent lamp used in a billboard, and a cold cathode fluorescent lamp 10 and an external electrode fluorescent lamp 14 are shown, respectively. The cold cathode fluorescent lamp 10 has a pair of electrodes 12 extending into the fluorescent lamp. In contrast, the external electrode fluorescent lamp 14 has an external electrode 16 surrounding the outer circumferential surface of the lamp end. A high voltage is applied from each inverter 12, 16 from an inverter (not shown).

FIG. 2 shows the external electrode fluorescent lamps 14 arranged in a state of being used in a billboard, and a high voltage is applied from the driving circuit 20 to the electrodes 16 of the plurality of fluorescent lamps 14 spaced at regular intervals. do. At this time, each of the electrodes 16 are connected in parallel using a wire 18 or a fixed PCB 34 and fixed by soldering.

3 shows a fixing part for accommodating the fluorescent lamp 14 and the electric wire 18. As shown in the figure, the upper plate 22 and the lower plate 28 are composed of semi-circular accommodating grooves 24 and 30, respectively. Support the end. In addition, the wire storage grooves 26 and 32 are formed between the receiving grooves, respectively, to constitute the wire storage grooves 26 and 32 through which the wires 18 pass.

In addition, in the case of the cold cathode fluorescent lamp 10, a fixing PCB 34 having a stripline 38 for power supply is extended in the longitudinal direction, and the electrode of the fluorescent lamp 10 is attached to the soldering pad 38a. 12) is soldered and fixed. On the other hand, a current limiting capacitor 36 is further attached to one side.

FIG. 4 is an enlarged view of the connection state of the electrode 12, and a current limiting capacitor 36 is further installed between the strip line extension 38b extending from the strip line 38 and the soldering pad 38a. It can be seen. Such a structure can be installed on one or both sides. In the structure provided with the fixing PCB 34 as described above, there is an advantage that it is not necessary to use the fixing part as shown in FIG.

Since the capillary fluorescent lamps use a high voltage of several kilovolts (KV) for operation, insulation of the electrode portion is a very important problem. However, the conventional fixing structure has a problem in that the failure rate due to long time use is high because there is a limit in blocking dust and moisture completely even though it is blocked from the outside by the case.

Moreover, when the fluorescent lamps are replaced, a plurality of fluorescent lamps must be fixed and soldered to the fixing parts, respectively, but it is very troublesome to replace them outdoors. Therefore, there is a need for a structure in which fluorescent lamps can be easily replaced.

The present invention is to solve the above problems, an object of the present invention is to prevent the damage of the high-voltage fluorescent lamp and / or inverter built into the billboard used in the external environment, the tubular fluorescent lamp of the billboard can improve the durability To provide a fixed case.

Thus, the molding material is used to completely block the ends and the connecting means of the fluorescent lamp from the outside to block the ingress of dust, moisture and / or dirt when used outside for a long time to improve durability, and to connect the fluorescent lamp and the power supply connecting means. By integrating and modularizing, it can be easily mounted on a billboard.

Figure 6 is one embodiment of a fixed case 40 of the present invention.

As shown, it is composed of a base 42 positioned below and a main body 41 positioned above the base 42. The base 42 has a screw insertion groove 44 formed at a predetermined position, and is fixed to a billboard (not shown) by using the screw 46. The base 42 may be formed not only on both ends shown in the drawing but also on the front and rear surfaces if necessary. In addition, it is possible to form and fix a receiving groove for accommodating the base 42 without using a screw at a corresponding position of the billboard.

The main body 41 is for accommodating the fluorescent lamp and accommodating connection means for supplying power to the fluorescent lamp. The main body 41 has a plurality of lamp storage grooves 48 and side grooves 49 formed at right angles to the lamp storage grooves 48 for this purpose. The lamp receiving grooves 48 are used to fix the end of the fluorescent lamp, the side grooves 49 are for fixing the connecting means for supplying power to the fluorescent lamp.

1, the connecting means may be an electric wire 18 or a fixing PCB 34. In particular, since the fixing PCB 34 is wider than the electric wire 18, the lamp storing groove 48 is provided. It can be positioned precisely by adjusting the length of.

The lamp receiving groove 48 may have a semi-elliptic shape or a straight shape to accommodate all of the ends of the fluorescent lamp, and may raise the electrode electrode PCB thereon. One end of the lamp housing groove 48 may be provided with a rubber ring (68). In addition, the main body 41 is preferably formed integrally with the base 42.

The rubber ring 68 may be used as a function of fixing the fluorescent lamp by having a size equal to or slightly smaller than the diameter of the fluorescent lamp. In addition, when molding the fixing case 40 of the present invention can be prevented from leaking the molding liquid to the outside. Detailed effects will be described later.

Referring to FIG. 7A, which is a plan view of FIG. 6, it can be seen that the lamp storage grooves 48 and the side grooves 49 formed on the upper surface of the main body 41 are formed in a mutually perpendicular state. By such a connection, a connecting means for supplying power to the side groove 49 is located, and the fluorescent lamp is positioned in the lamp storage groove 48. Before fixing the fluorescent lamp, the electrode and the connecting means of the fluorescent lamp may be electrically coupled using soldering. At both ends, screws 46 are fixed to the base 42 and used to fix the billboards.

The lamp receiving groove 48 should have a depth sufficient to essentially accommodate all of the ends of the fluorescent lamp, and may be configured as a rectangle, semicircle, straight or semi-elliptic as shown in the drawing. Lamp receiving groove 48 is preferably to be fixed naturally when the fluorescent lamp is accommodated. In addition, it is apparent that the height of the body 41 may be changed depending on the billboard to which the fixed case 40 is applied.

In addition, each lamp storage groove 48 is provided with a rubber ring 68 as shown to secure the fluorescent lamp securely. The rubber ring 68 may also be usefully used for injection of a molding liquid for blocking the outside after mounting the fluorescent lamp and the connecting means in place. That is, when the molding liquid is injected into the space formed in the main body 41, the molding liquid may be used to prevent leakage of the molding liquid to the outside.

In addition, the side grooves 49 indicated by dotted lines can adjust the depth according to the size of the fluorescent lamp. In other words, in the case of the cold cathode fluorescent lamp 10, since the electrode 12 is located at the center of the side surface of the fluorescent lamp, the depth of the side groove 49 is adjusted in accordance with the height of the electrode 12. Accordingly, the electrode 12 of the fluorescent lamp 10 is positioned on the soldering pad (38b of FIG. 5) of the connecting means positioned in the side groove 49. On the other hand, in the case of the external electrode fluorescent lamp 14, the height of the side grooves 49 is not a big problem.
