Description

  The present invention relates to an advertisement lighting device that illuminates a panel provided on a surface by providing a fluorescent lamp inside and emitting light from the fluorescent lamp.

  In the upper part of the pillar and the upper part of the building, there is provided an advertising illumination device that illuminates a panel provided on the surface by providing a fluorescent lamp inside and emitting light from the fluorescent lamp. As a fluorescent lamp used in this advertising lighting device, a fluorescent lamp called an external electrode fluorescent lamp having a small diameter is used from a general fluorescent lamp as shown below.

Figure 26 is a conventional general hot-cathode tube is a fluorescent lamp is a graph showing an emission principle (hereinafter referred HCFL lamp. Ho t Ca thode Fl ourescent La mp). As is well known, the HCFL lamp 1 includes a glass tube 2, a phosphor 3 applied over the entire inner peripheral surface of the glass tube 2, and a pair of filaments provided inside both ends of the glass tube 2. 4. The glass tube 2 contains an inert gas atom and a small amount of mercury atom.

  In the HCFL lamp 1, inert gas atoms and thermoelectrons enclosed in the glass tube 2 are similarly encapsulated by thermionic radiation generated by energizing and heating the filament 4 in the glass tube 2. It collides with a small amount of mercury atoms and is excited to generate ultraviolet rays. This ultraviolet light causes the phosphor 3 on the tube wall to emit light.

In contrast the cold cathode tube (hereinafter, CCFL lamp that. Co ld C athode F lourescent L amp), the filaments without a method to discharge by applying a high voltage to the electrode.
FIG. 27 is a diagram showing the light emission principle of the CCFL lamp 6, and a pair of electrodes 7 are provided inside both ends of the glass tube 2. By applying a voltage to the electrodes 7 at both ends, a discharge is performed at the tip of the electrode 7, and a current flows in the glass tube 2. Further, the cathode fall voltage is large in a portion in the glass tube 2 near the electrode 7 (portion drawn in gray).

  The CCFL lamp 6 can have a smaller electrode structure than the HCFL lamp 1, is thin, has a long lamp life, and has a wide range of uses. However, the CCFL lamp 6 is inferior to the HCFL lamp 1 in terms of luminous efficiency because the cathode fall voltage in the vicinity of the electrode 7 is large as described above.

Figure 28 is an external electrode fluorescent lamp has been attracting attention recently is a graph showing an emission principle (hereinafter referred EEFL lamps. Ex ternal E lectrode F lourescent L amp). In the EEFL lamp 10, electrodes are not provided in the glass tube 2, but electrodes 11 are provided outside both sides of the glass tube 2.
The EEFL lamp 10 is the same cold cathode tube as the CCFL lamp 6 described above, and the principle of light emission is the same. The difference between the two is that the electrode 7 of the CCFL lamp 6 is in the glass tube 2 and electrons also run in the glass tube 2, whereas in the EEFL lamp 10, the electrode 11 is installed outside the glass tube 2, and the glass tube The electrons run outside of 2. As a result, the EEFL lamp 10 is characterized in that the cathode fall voltage is reduced, light is emitted with low power consumption, and the heat generation of the lamp is also extremely reduced.

  As shown in FIG. 29, the CCFL lamp 6 has a negative resistance characteristic that its resistance value decreases as the current increases, as shown in FIG. 29. Therefore, a plurality of CCFL lamps 6 are connected in parallel. However, there is a problem that only one of them is lit.

On the other hand, since the EEFL lamp 10 has positive resistance characteristics as shown in FIG. 30, it can be lit even if a plurality of EEFL lamps 10 are connected in parallel. In addition, the EEFL lamp 10 requires a high-frequency power source of about 60 KHz and a high voltage of about 1.6 KV for driving due to its characteristics.
The EEFL lamp 10 has a small diameter, and a plurality of EEFL lamps 10 can be activated / lighted by a single inverter device. Therefore, in a market where a thinner advertising lighting device is required, It has been gradually used recently.

However, when the advertising lighting device using the EEFL lamp 10 is installed on a pillar or the like, there are various problems as described below.
That is, FIG. 31 shows a diagram in which an advertising lighting device 81 is installed on a pillar 80. This advertising lighting device 81 is mounted on a metal case main body 82 having an open front surface and a front opening surface of the case main body 82. The outer shell is constituted by the panel-shaped diffusion plate 84 to be formed.

  For example, Non-Patent Document 1 shown below is an example of the advertising lighting device 81 having this configuration and a conventional construction method for the advertising lighting device 81.

PLASMA-EEFL LAMP catalog of Ten Industries Co., Ltd.

As shown in FIG. 32, the conventional advertising lighting device 81 is provided with a reflecting plate 85 for reflecting light from the EEFL lamp 10 to the front side on the back surface of the case body 82. For example, three support bases 86 are arranged in the up-down direction on the front surface.
The support base 86 is formed in a flat and thin plate shape, and a number of elastic fasteners 87 having a cross section of approximately Ω in the lateral direction are provided on the front surface of the support base 86 according to the number of EEFL lamps 10. Only provided. The EEFL lamp 10 is detachably attached to the fastener 87.

Next, a conventional construction method for the advertising lighting device 81 will be described. It should be noted that the installation position of the advertising lighting device 81 on the pillar 80 is generally 3 to 4 meters above the floor surface, and the operator works on a ladder or stepladder outside the figure. To do.
First, the worker climbs a ladder or the like and bolts the case main body 82 of the advertising lighting device 81 at a predetermined position, and then attaches a predetermined number of EEFL lamps 10 to the fasteners 87 of the case main body 82 as shown in FIG. Fit one at a time. In the advertising lighting device 81 using the EEFL lamp 10, about 10 lamps are used because of the wattage (brightness) of the EEFL lamp 10. Therefore, when all the EEFL lamps 10 are attached to the case main body 82, it is necessary to go up and down the ladder several times.

Next, the socket 11 is fitted to the electrodes at both ends (upper and lower ends in the figure) of the mounted EEFL lamp 10. After the socket 11 is mounted, a voltage application cord (not shown) is connected between the sockets 11, and the socket 11 connected with the cord is inserted and connected to the electrode of the EEFL lamp 10.
Next, the illuminating plate 81 is installed on the column 80 by bolting the diffusion plate 84 to the opening surface of the case body 82.

  However, the back surface of the case main body 82 is formed with a reflection plate 85 integrally formed as a back plate of the case main body 82, so that the weight of the case main body 82 is heavy and rests on a ladder or a stepladder. Installation work at high altitudes is not smooth and dangerous. Also, the installation work of the EEFL lamp 10 after the installation of the case main body 82 has to go up and down the ladder several times, which is not easy to work and the EEFL lamps 10 one by one in the high place. It is necessary to attach to the fasteners 87, so that it is always next to danger.

Further, the mounting work of the EEFL lamp 10 to the fastener 87 is a work at a high place, and since the tube diameter of the EEFL lamp 10 itself is small, the EEFL lamp 10 may be broken. Therefore, construction workability is very poor and the construction time becomes long.
Also, when installing a plurality of advertising lighting devices 81, the overall construction time becomes very long, especially when a large number of advertising lighting devices 81 are installed in the same place (building). As a result, the EEFL lamp 10 is damaged, and the installation work of one advertising lighting device 81 becomes longer and the risk is further increased.

Further, even after the installation of the advertising lighting device 81, the diffusion plate 84 is only bolted on the front surface. Therefore, dust easily enters the inside. Can be visually recognized and give a bad impression.
Further, when the EEFL lamp 10 is defective and stops lighting, even when the EEFL lamp 10 is replaced, the diffusion plate 84 is removed, the socket 11 is removed from the defective EEFL lamp 10, and the EEFL lamp 10 is fastened. 87 and then replaced with a new EEFL lamp 10. Also in this case, the socket 11 is fitted after the EEFL lamp 10 is mounted.

In such a case, since the EEFL lamps 10 are disposed relatively close to each other and the work is performed at a high place, there is a problem that the replacement work of the EEFL lamps 10 is not smoothly performed. In addition, when the advertising lighting device 81 is forgotten to be turned off, a high voltage of about 1.6 KV is applied to the EEFL lamp 10 as described above, which may cause an electric shock and is particularly dangerous. .
As described above, in the installation work of the conventional advertising lighting device 81, the danger is great, the installation work is not easy, and the construction time is particularly long. In addition, there are difficulties in terms of safety, and there are many problems that dust easily enters inside.

The present invention is provided in view of the above-described problems, and provides an advertising lighting device having at least the following objects.

Further, the inverter device 15 and the power supply device 16 are accommodated in the light unit 22, and specifically, disposed on the inner side surface of the side piece 53 of the support body 52 as shown in FIG. 6. The power cord 17 from the power supply device 16 is led out from the hole 56 of the support body 52. Here, the inverter device 15 and the power supply device 16 are directly fixed to the inner surface of the side piece 53 of the support body 52 of the light unit 22, and therefore the support body 52 serves as a heat sink and generates heat. The device 15 and the power supply device 16 are cooled.

As described above, the light unit 22 according to the present invention includes the EEFL lamp 10 as well as the inverter device 15 and the power supply device 16 inside, and the light unit 22 includes only the power cord 17 provided with the connector 18. Is derived, and the energized portion is not exposed to the outside.
Therefore, no matter where the outer surface of the light unit 22 is touched, there is no electric shock and the safety is greatly improved.

16 and 17 show a case where the front plate 51 is fixed to the support body 52 with the adhesive tape 73. FIG. The reflection plate 50 and the front plate 51 are fixed to the support body 52 without using screws or eyelets. For example, the reflection plate 50 is formed of the rear piece 55 of the support body 52 with an adhesive or double-sided tape. Adhere to the inside and fix.
Then, after the front plate 51 is aligned with the front pieces 54 of the support bodies 52 on both sides, the adhesive tape 73 is applied to the end portions of the front plate 51 and the side pieces 53 of the support body 52 in the vertical direction. The front plate 51 is fixed to the support body 52 by pasting.

  Thereby, compared with the case where the reflecting plate 50 and the front plate 51 are fixed to the support body 52 with screws or eyelets, the manufacturing process time of the light unit 22 can be significantly shortened. Further, since the front plate 51 and the like are simply fixed with the adhesive tape 73, no special skills are required for manufacturing, and anyone can easily and quickly manufacture. That is, since the front plate 51 is fixed by the adhesive tape 73, the assembling workability can be improved, and as a result, the cost of the light unit 22 can be reduced.

  FIG. 18 is an enlarged cross-sectional view of the reflector 50 of the light unit 22, and a back plate 66 made of black styrene is used as an adhesive 67 on the back surface of a reflector 65 made of white PET (polyethylene terephthalate) on the EEFL lamp 10 side. And are integrally configured by heat and pressure. That is, the reflecting plate 50 has a three-layer structure of a reflector 65 layer, an adhesive 67 layer, and a back plate 66 layer, and the thickness of the reflecting plate 50 itself is 1 mm or less. Of course, the thickness of the reflecting plate 50 may be about 1 to 2 mm, and the material is also made of synthetic resin, so that the weight can be reduced.

  By the way, FIG. 19 shows a case where the reflecting plate 50 is configured by only the reflector 65 made of white PET, and a general reflecting plate is configured by only the reflector 65. In the reflector 50 constituted only by the reflector 65, although the light from the EEFL lamp 10 can be normally reflected, the light is transmitted as shown by the arrow A in the figure, and light leakage is inevitably caused. The light from the EEFL lamp 10 cannot be effectively reflected to the front side. Therefore, the reflected light cannot be used effectively over the entire surface, and the front surface of the advertising lighting device 20 cannot be illuminated with a predetermined brightness or higher.

  Moreover, like the advertising lighting device 20 of the present invention, when light leaks from the reflector 50 to the rear, the light leak becomes conspicuous at night, giving a bad impression. In order to prevent this light leakage, it is necessary to block the entire back surface of the case main body 21, the openings 31 and 32 cannot be formed, and the weight of the case main body 21 becomes heavy. The risk of installation work increases.

  However, in the present invention, as indicated by an arrow B in FIG. 18, even if light from the EEFL lamp 10 passes through the reflector 65, it is totally reflected by the back plate 66, and light from the EEFL lamp 10 is reflected. Can be used effectively.

In addition, it is possible that the reflector is made of metal and the surface is colored white to totally reflect the light. However, when the reflector is made of metal, the weight is very heavy and the cost is low. Also up.
In the present invention, from the viewpoint of weight reduction and cost reduction, the reflector 50 itself is made of synthetic resin, and a black back plate 66 is attached to the back surface of the reflector 65 to prevent light leakage through the back surface. Can be completely eliminated. Further, also in relation to the wavelength, a reflectance of almost 100% is obtained over a wavelength of 800 nm from 400 nm before.

  In particular, since light leakage from the EEFL lamp 10 to the rear at the reflector 50 is completely eliminated, there is no light leakage from the rear of the advertising lighting device 20, so that the case main body 21 has a structure as described above. The openings 31 and 32 can be formed, the weight of the case body 21 can be reduced, and the safety of installation work at a high place can be improved.

Next, the construction of the advertising lighting device 20 will be described. First, the case main body 21 and the light unit 22 are manufactured separately, and the case main body 21 is first installed on the construction surface, and then the light unit 22 is detachably attached to the case main body 21 in a cassette type. is there.
The case main body 21 is installed at a predetermined position such as a pillar or a wall surface. In such a case, a ladder or a stepladder is used because the height is 3 to 4 meters from the floor as in the conventional case.

  Although the case body 21 itself is made of metal, since the large openings 31 and 32 are formed in the back plate 30 of the case body 21 as described above, the weight is light and the work at a high place is facilitated. . That is, since the case main body 21 is lightweight, the feet do not wobble even when climbing on a ladder and installed on a pillar or the like, and even when the case main body 21 is bolted, the bolting can be performed smoothly.

  The case main body 21 is composed of a main body frame 23 and a frame 24, and both are connected by a hinge portion 25. Therefore, the hinge portion 25 is disassembled in advance, and the main body frame 23 and the frame 24 are separated. And are separated. Then, only the main body frame 23 may be installed on the pillar first, and then the frame 24 may be attached to the case main body 21. In such a case, since the weight can be reduced by the amount of the frame 24, the installation work of the main body frame 23 can be performed more efficiently and smoothly.

After the case body 21 is installed on the pillar, the light unit 22 is brought and the connector 37 (see FIG. 5) on the case body 21 side and the connector 18 (see FIG. 1) on the light unit 22 side are connected. Next, as shown in FIG. 2, the light unit 22 is slightly lifted and the upper portion of the light unit 22 is tilted slightly forward so that the protrusion 41 on the lower portion of the case body 21 is inserted into the insertion hole 61 of the light unit 22. The light unit 22 is lowered.
Next, the light unit 22 is pushed backward so that the fixing rod 42 at the top of the case body 21 is inserted into the insertion holes 49, 57, 58 of the light unit 22. Next, as shown in FIGS. 20 and 21, the light unit 22 is mounted in the case main body 21 by screwing the screw 44 into the screw portion 43 of the fixing rod 42. Then, the advertising lighting device 20 is installed on the pillar by closing the frame 24 to the case body 21 side.

  A power cord 36 connected to an external power source is introduced into the case body 21 to connect the connector 18 of the power cord 17 led out from the light unit 22 and the connector 37 of the power cord 36. Therefore, the connection of the power cord to the light unit 22 is also simple.

FIG. 22 shows the advertising lighting device 20 with the light unit 22 mounted in the case body 21. As described above, since the light unit 22 has a substantially sealed structure except for the insertion hole 56 for the power cord 17, it is possible to almost prevent the entry of dust into the light unit 22, and the brightness of the illumination by the dust. It is possible to prevent the reduction of the thickness and the adverse effect on the appearance.
In addition, since the light unit 22 itself is sealed by the frame 24 provided with the panel 27 and the case main body 21, it is possible to further prevent dust from entering the light unit 22.

  In addition, when replacing one EEFL lamp 10 in the light unit 22 without being lit, the frame 44 is opened and the screws 44 fixing the light unit 22 are removed to remove the light from the case body 21. Remove the entire unit 22. Then, the replacement light unit 22 is attached to the case body 21 in the same manner as described above. To replace the defective EEFL lamp 10, the light unit 22 is brought back to the company, the light unit 22 is disassembled, and only the defective EEFL lamp 10 is replaced with a new EEFL lamp 10.

Thus, in this embodiment, since the light unit 22 is detachably mounted in the case main body 21 previously installed in a cassette type, the place where the advertising lighting device 20 is installed is a high place. Even in this case, unlike the conventional case where lamps are mounted one by one, the construction can be made very easy, and the light unit 22 is simply mounted on the case body 21 side in a cassette type. The construction time can be greatly reduced.
Also, when replacing the lamp, the light unit 22 and the light unit 22 are simply removed from the case body 21 and a new light unit 22 is mounted on the case body 21. Unlike the conventional case where the lamp itself is replaced, there is a risk of electric shock. There is absolutely no safety can be greatly improved.

  In addition, a protrusion 41 is erected on the lower portion of the case main body 21, and a fixing rod 42 is protruded toward the front on the upper portion of the case main body 21. An insertion hole 61 into which the protrusion 41 is inserted is drilled, and insertion holes 49, 57, 58 into which the fixing rod 42 of the case body 21 is inserted are formed in the upper part of the light unit 22. Since the light unit 22 is detachably attached to the case body 21 by screwing to the fixing rod 42 through the insertion holes 49, 57, 58, the light unit 22 is attached to the case body 21. The light unit 22 can be mounted in a short time. Further, the structure for attaching the light unit 22 to the case main body 21 can be simplified, and the cost can be prevented from being increased.

  In addition, since the EEFL lamp 10 is used as the lamp used in the advertising lighting device 20, the EEFL lamp 10 has a small diameter. Therefore, the advertising lighting device 20 itself can be reduced in thickness and weight. Thus, the construction safety of the advertising lighting device 20 can be further enhanced.

  In the above embodiment, the lamp provided in the light unit 22 is described as the EEFL lamp 10, but the present invention can also be applied to an HCFL lamp or a CCFL lamp.

  23 and 24 show another example in which the light unit 22 is detachably attached to the case body 21 in a cassette type. That is, in the previous embodiment, in order to fix the light unit 22 to the case main body 21 side, the protrusion 41 and the fixing rod 42 are protruded by welding or the like on the case main body 21 side. An insertion hole 61 for inserting 41 is formed in the support 52, and insertion holes 57 and 58 for inserting the fixing rod 42 are drilled in the support 52, and an insertion hole 49 is also drilled in the reflector 50. Was.

  When the protrusion 41 and the fixing rod 42 are provided on the case main body 21 side by welding, there has been a problem that the working time is increased and the cost is considerably increased. Further, when the insertion hole 61 into which the protrusion 41 is inserted is drilled in the support body 52 of the light unit 22, the tongue piece 48 bent at the lower part is drilled or the insertion hole 49 is also drilled in the reflector 50. As a result, the working time and cost were significantly increased. In addition, the structure of the support 52 is complicated, and the cost associated with the bending work of the tongue piece 48 and the drilling work is higher than the material cost.

  Therefore, in this embodiment, such work is completely eliminated, the working time is greatly reduced, and the advertising lighting device 20 is created at a very low cost. The attachment and detachment operations to and from the light unit 22 are greatly simplified.

  That is, as shown in FIG. 23, hook-and-loop fasteners 74 are attached to the four corners of the back plate 30 of the case body 21, and the hook-and-loop fasteners 74 are opposed to the positions of the back surface of the light unit 22 corresponding to the hook-and-loop fastener 74. A hook-and-loop fastener 75 is attached. In this example, four hook-and-loop fasteners 74 and 75 are used, but it goes without saying that an arbitrary number of hook-and-loop fasteners 74 and 75 is used depending on the size of the advertising lighting device 20.

In this embodiment, a predetermined number of hook-and-loop fasteners 74 need only be attached to the case body 21 side with an adhesive, and the hook-and-loop fastener 75 is also attached to the light unit 22 side with an adhesive. Just leave it. Therefore, it is not necessary to provide the protrusion 41 and the fixing rod 42 on the case body 21 as in the previous embodiment, and it is not necessary to provide an insertion hole or an insertion hole into which the protrusion 41 or the fixing rod 42 is inserted.
In particular, in the previous embodiment, when the insertion hole 61 is provided in the support body 52, the tongue piece 48 is bent or the two insertion holes 57 and 58 are perforated. The structure of the support body 52 may be simply folded into a U shape, and the structure of the support body 52 can be greatly simplified. Therefore, the manufacturing time of the case main body 21 and the light unit 22 can be shortened, and an extra process can be omitted, so that the manufacturing cost can be made extremely low.

Further, when the light unit 22 is mounted on the case main body 21, it is only necessary to align the surface fastener 75 of the light unit 22 with the surface fastener 74 of the case main body 21, and the installation work at a high place can be performed more smoothly. it can. This can greatly improve the safety of installation work at high places.
Further, when removing the light unit 22, the light unit 22 can be easily detached from the case body 21 by pulling the light unit 22 with a little force.

  25 shows another embodiment of the light unit 22, and compared with the light unit 22 shown in FIG. 7, a right piece 68 and a left piece 69 each having a substantially rectangular cross section from both sides of the reflector 50. Are integrally formed like the upper piece 59 and the lower piece 60. In this embodiment, both supports 52 and 52 are arranged inside the both sides of the reflecting plate 50, respectively.

  That is, the right piece 68 of the reflecting plate 50 covers the side piece 53 of the support 52 from the outside, and the adhesive piece 68 a at the tip of the right piece 68 is attached to the front surface of the front piece 54 of the support 52. Further, the left piece 69 covers the side piece 53 of the other support member 52, and an adhesive piece 69 a at the tip of the left piece 69 is attached to the front surface of the front piece 54 of the support member 52.

The upper piece 59, the lower piece 60, the right piece 68 and the left piece 69 are integrally formed from the reflector 50, and the structure thereof is the same as that of the reflector 50 shown in FIG. As well as the back of 50, light leakage in the vertical and horizontal directions is reliably prevented.
Therefore, when the advertising lighting device 20 is formed by mounting the light unit 22 configured using the reflector 50 shown in FIG. 25 in the case body 21, the rear and vertical directions from the advertising lighting device 20 are formed. , Light leakage in the left-right direction can be completely prevented.

  In the embodiment shown in FIG. 25, since the support bodies 52 on both sides are covered from the outside, it is particularly effective when the support bodies 52 are made of a synthetic resin that easily transmits light.
