[Industrial use]

The present invention relates to a matrix device of a gas discharge lamp, and more particularly to a tube lamp matrix device having a longer service life than a conventional gas discharge lamp.

[Private Technology]

The conventional neon lamp 10 is a thin U-shaped glass tube 12 and a positive electrode 14 provided at both closed ends of the glass tube 12, as shown in the example of FIG. The glass tube 12 is filled with a suitable working gas, for example, neon or the like, inside the vacuum, and a predetermined voltage is applied between the two electrodes 14 so that the neon lamp 10 emits color rays. Therefore, the positive electrode 14 is connected to an external power source (not shown) by sandwiching the conductive wire 14a.

This type of conventional neon lamp 10 has the following drawbacks.

The final process of extracting air from the glass tube 12 into a vacuum is very difficult. Usually, a small amount of foreign matter or other gas remains in the glass tube 12, and the lamp 10 is operated at high speed. When used for a long time in the temperature, foreign matter remaining in these glass tubes generates a chemical reaction between the positive electrode 14, thereby promoting corrosion of the positive electrode 14, thereby shortening the service life of the neon lamp 10.

Since the conducting wire 14a of the both electrodes 14 penetrates the both ends of the glass tube 12, a working gas often leaks from both ends of the neon lamp 10, and the internal volume of the glass tube 12 is reduced. Since the leakage rate of the working gas is high with respect to the relatively small one, the working gas is insufficient to emit sufficient light, or the color of the emitted light is modulated and the effect of action is lost.

A fluorescent layer coated with a fluorescent material is provided on the inner circumferential wall of the lamp tube 12. When the fluorescent layer fades due to long-term use, the glass tube 12 is also discarded, which is wasted.

When the neon lamp 10 is installed and used in an advertisement lamp matrix device, many accessory parts are required, so that the assembly of the lamp matrix device is complicated and the cost is high.

[Problems to Solve Invention]

In view of the problems of the conventional lamp matrix device described above, an object of the present invention is to provide a tube lamp matrix device which has a relatively long service life, can be easily assembled, and can reduce manufacturing costs.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a plurality of sealed and long first gas containers arranged in parallel and a plurality of sealed and lengths intersected at an appropriate angle with the first gas container and arranged in parallel on another coplanar surface. A first gas container set including a second long gas container and filling a gas into each gas container;

Both ends of the plurality of elongated glass tubes having a smaller cross-sectional area than the first and second gas containers are formed as open ends, and both opening ends of each glass tube are inserted into and sealed in the first gas container and the second gas container, respectively. Thus, the first glass tube matrix formed by filling the working gas also in the glass tube is combined, and a pair of electrodes are connected to the external power source by inserting conductors in the first gas container and the second gas container. By applying a sufficient voltage between both electrodes in each gas container, the working gas in each glass tube is discharged, and it is comprised so that a light ray may be emitted.

A protective cap is coated on each of the glass tubes, and the protective cap is stretched in an almost orthogonal direction from the upper opening portion and the edge around the upper opening portion to form an enclosing portion coated with a reflective layer on the inner circumferential wall. Coating or inserting a band color filter layer, a glass layer, and a fluorescent layer of a fluorescent material in order from the inside out; The cross-sectional area of each of the first and second gas containers is larger than the total cross-sectional area of the plurality of glass tubes connected thereto; A plurality of second gas container sets and second glass tube matrices disposed in the first gas container set and the first glass tube matrix, and the second gas container set arranged in parallel between both first gas containers adjacent to each other. And a plurality of fourth gas vessels arranged in parallel between the third gas vessel and the adjacent two second gas vessels, wherein the second glass tube matrix is interposed between the first glass tube matrix, A plurality of elongated glass tubes having a smaller cross-sectional area than those of the third and fourth gas containers are provided, and one end of each glass tube formed at both ends with an open end is inserted into the third gas container, and the other end is hermetically connected. Inserted into the fourth gas container and connected in an airtight manner, a pair of electrodes are built into each of the third and fourth gas containers and different from those used in the first glass tube matrix. Filled with a working gas so that, upon discharge, each glass tube of the second glass tube matrix emits a different color ray than each glass tube of the first glass tube matrix and a spare electrode inside each gas container. It is more preferable to install more.

[Action]

The present invention configured as described above, in the first gas container set, the cross-sectional area of the first gas container and the second gas container is formed at both ends by the open end and inserted into the first and second gas containers as airtight frames, respectively. Since it is considerably larger than each of the glass tubes connected to each other, supplying sufficient electric power to both electrodes in each gas container from an external power source generates a very high voltage inside each glass tube, and the operating gas in these glass tubes is discharged, resulting in high luminance. Rays of light are emitted.

The glass cap is coated on each of the glass tubes, and the color filter layer, the glass layer, and the fluorescent layer of the fluorescent substance are sequentially coated or provided on the inner wall surface of the upper portion of the protective cap. The layer can filter harmful ultraviolet rays and emit other color rays by chemical action at the filtration action of the color filter layer and at the high operating temperature of the color filter layer or the fluorescent layer.

Alternatively, if a plurality of second gas container sets and second glass tube matrices are disposed in the first gas container set and the first glass tube matrix, for example, a tube lamp matrix device that emits various different color rays may also be formed. Can be.

Furthermore, since the spare electrode is provided inside each gas container, and the gas internal volume is considerably larger than the internal volume of the conventional neon lamp, and the leakage rate of the working gas is extremely small, the service life of each gas container becomes longer, Furthermore, the service life of the entire tube lamp matrix device is extended.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description with reference to the drawings.

EXAMPLE

First, before the description, similar parts disclosed in the description are given the same reference numerals.

1 and 2 are diagrams of a first embodiment of the present invention, as shown, comprising a plurality of glass tubes 40 arranged on a working gas container set and a matrix,

The working gas container set includes a plurality of parallel sealed rectangular first gas containers 20 and a plurality of second sealed rectangular gases arranged in parallel in the same plane crossing the first gas container 20 at an appropriate angle. It consists of a container 30.

In the present embodiment, the first gas container 20 and the second gas container 30 are arranged to be perpendicular to each other, and the operating gas, for example, neon, argon, in each of the gas containers 20 and 30 is arranged. When the mercury vapor or the like is injected (or the gas bottle 70 may be laid and supplied), the radiant energy is discharged from the working gas when the voltage is applied, and the first gas container 20 and the second gas container ( The cross-sectional shape of 30 may be round, oval or rectangular as shown.

The glass tube 40 exhibits an elongated tube state, and may be provided in a substantially U-shaped or spiral shape shown in the present embodiment, and each glass tube 40 is formed as shown in FIG. Both opening ends are hermetically inserted into the first gas container 20 and the second gas container 30, respectively, and each glass tube 40 is inside the first gas container 20 and the second gas container 30. And the working gas is also communicated with each glass tube 40.

The outer shape of the glass tube 40 may be arbitrarily designed in response to the surrounding environment. However, when the outer shape is lengthened, there is a merit in which the emission area of the light beam is widened to obtain a relatively good luminous intensity.

These glass tubes 40 have a smaller cross-sectional area than the first gas vessel 20 and the second gas vessel 30, and the cross-sectional areas of the first gas vessel 20 and the second gas vessel 30 are Although it can enlarge suitably according to the volume of the operation gas required, it is important to make the cross-sectional area of each gas container 20,30 larger than the total cross-sectional area of the glass tube 40 connected to it.

The first and second gas containers 20 and 30 are further provided with a pair of electrodes 50 and 60 therein, and the two electrodes 50 and 60 are externally fitted with a wire. It is connected to the power supply.

Since the first and second gas containers 20 and 30 have a larger cross-sectional area than those of the glass tubes 40, the first and second gas containers 20 and 30 have a larger cross-sectional area than the respective glass tubes 40. The light rays emitted and discharged by the working gas are relatively dark, and conversely, sufficient discharge voltages are in contact with the first and second gas containers 20 and 30 applied between the positive electrodes 50 and 60, respectively. Since the tube 40 side generates a considerably high voltage in each unit volume, and the working gas therein discharges and emits a considerably bright ray, the first and second gas containers 20 are separated from both contrasts. ), 30 do not emit light, and each glass tube 40 is seen as a line that emits light.

Each of the first and second gas containers 20 and 30 may further have spare electrodes 50a and 60a therein, so that the main electrodes 50 and 60 are aged for long term use. The tube lamp matrix device can still function even if it becomes unusable, and the contents of each gas container 20, 30 are sufficiently larger than a conventional neon lamp, even if the same amount of working gas leaks out. Since there is a very big difference in the rate, the service life of the gas container of the present invention becomes relatively long.

Although the voltages passing through the positive electrodes 50 and 60 of each of the first and second gas containers 20 and 30 can be used regardless of DC (direct current) or AC (AC), If a DC voltage is used, bidirectional scanning is possible.

It is most preferable that the glass tube 40 is made of molten quartz glass, and, as is known, the molten quartz glass has ultraviolet radiation characteristics.

In the present invention, the tube lamp matrix device further comprises a plurality of protective caps 42 each surrounded by a glass tube 40, and as shown in Figs. 2 and 3, the protective caps 42 have an upper portion. 424 and an enclosure 422, the enclosure 422 extends from the periphery of the upper opening 424 so that a reflective layer 4202 is coated on the inner circumferential wall, so that the enclosure 22 is Reflecting most of the light rays emitted from the working gas in the glass tube 40 to the top portion 424, the top portion 424 is made of lead glass, and also the band color filter from inside to outside on the inner wall surface The layer 4244, the glass layer 4245, and the fluorescent layer 4246 made of a fluorescent material are coated or provided in this order.

Among them, the fluorescent layer 4246 receives ultraviolet rays to generate colcr rays, and the color filter layer 4244 filters and changes color rays from the fluorescent layer 4246 to a desired color. Only light passes through, and the glass layer 4245 filters out harmful ultraviolet light to prevent the color filter layer from fading.

In this first embodiment, the first and second gas vessels 20 and 30 are filled with the same kind of operating gas, and therefore, each glass tube 40 emits the same light rays. The tube lamp matrix device is capable of emitting different color rays by the chemical action of the color filter layer 4244 or the fluorescent layer 42262 coated on the inner circumferential wall of the upper portion 424 of the protective cap 42. The other color rays emitted from the tube lamp matrix device are seen as if they are radiating an infinite number of colors.

The upper part 424 may be detachably attached to the upper edge of the enclosing part 422, and thus can be replaced when the fluorescent layer 4246 of the upper part 424 becomes thin or discolored.

The gas container 20b is installed between each of the first gas containers 20a in parallel with the first gas container 20a, and each of the fourth gas containers 30b is parallel to the second gas container 30b. Thus, they are respectively installed between both second gas containers 30a.

It inserts in the container 20b, and it connects in an airtight phase, inserts another end in the 4th gas container 30b, connects in an airtight manner, and makes three characters communicate with each other, and a color light beam different from the said 1st operating gas at the time of discharge is carried out. The emitting second working gas is filled in each glass tube 40b.

The third gas container set is formed of a plurality of fifth gas containers 20c arranged in parallel and a sixth gas container 30c arranged in parallel to and intersected with the plurality of fifth gas containers 20c. The gas vessel 20c is connected to the first and third gas vessels 20a and 20b in parallel with the first and third gas vessels 20a and 20b, and then installed.

The sixth gas container 30c is installed after connecting to the second and fourth gas containers 30a and 30b in parallel with the second and fourth gas containers 30a and 30b, respectively. .

One end is inserted into the fifth gas container 20c and connected in an airtight phase, and the other end is inserted into the sixth gas container 30c and connected in an airtight phase, and the three characters communicate with each other so that the first and second parts are discharged. It is to fill each glass tube 40c with the 3rd operation gas which radiates a color ray different from 2 operation gas.

In this second embodiment, the first, second and third working gases can selectively emit different colored light rays, for example red, blue, green, etc., and each glass tube When the cap unit (not shown) corresponding to 40a, 40b, and 40c is suitably coated, by this, the kind of the color light ray which can be emitted from the tube lamp matrix apparatus of this invention becomes more diverse. .

Moreover, the number of gas container sets and the number of glass tube matrices of the working gas may be added or subtracted as necessary, and a further preferable effect can be expected.
