The display device is composed mainly of a lower base 1 embedded in a foundation G constituting a road, a floor, and the like, and a number of display units 2 attached to the lower base 1 from above. All or most of the upper surface except the upper surface is embedded in the foundation G. The display unit 2 has a length of, for example, about 30 cm and has an elongated shape, and an elongated light-transmitting portion 3 is formed on the upper surface. A light-emitting diode as an example of a point light source (to be exact, a light-emitting diode lamp) A large number of 4 are arranged in a flying state. Further, both ends of the display unit 2 are constituted by end caps 5 and 5 '. In this reference example , the total height of the display device is set to about 80 mm.

A cable 6 for power supply and control of the light emitting diode 4 is exposed from the lower surfaces of both ends of each display unit 2, and a connector 7 is connected to the cable 6. Therefore, the cables 6 of the adjacent display units 2 are connected by the connector 7. Although not described in detail, it is preferable that the main power supply line and the branch power supply line branched from each unit 2 are wired to each unit 2 and power is supplied to the light emitting diode 4 from the branch power supply line (one display unit 2). since in even trouble such as disconnection, it does not affect the other display unit 2.).

It is also possible to adopt a wiring mode in which the power line and the control line are provided separately from each display unit 2 and the power line and the control line are connected to the internal line of each display unit 2 with a connector. is there. The length of the lower base 1 can be arbitrarily set. For example, the length of the lower base 1 can be set to about 10 m to form one block, and a large display device can be configured by arranging a number of blocks in series. Is possible. In this case the display device is long as a whole, as preferably provided a repeater every many meters or (or per block). The display device also includes a control panel (not shown) separated from the lower base 1 and the display unit 2.

The structure of the foundation G differs depending on the type of construction site. For example, in the case of a station platform or premises, the whole is often concrete, and in the case of a road (roadway), asphalt is often laid on a base made of gravel, earth, or concrete. When the asphalt is laid on the base, the lower base is often placed on the base such as gravel, and the display unit 2 is often embedded in the asphalt. All of the devices high is preferably is set to the same degree of size as the thickness of the asphalt layer.).

  Most of the sidewalks are constructed by placing concrete or paving stones (or tiles) on a gravel or earth base. In this case, the display unit 2 is placed on the base. It can be said that it is often in a state. The road surface of a sidewalk or a plaza may be made of wooden tiles. In this case, the display unit 2 is sandwiched between wooden tiles.

(2). Components / External Structure The lower base 1 is an extruded product of aluminum or aluminum alloy, and includes a horizontal lower plate 9 and two left and right side plates 10 rising upward. Are integrally connected by a reinforcing plate 11 at a lower portion thereof. In addition, a lower engagement claw 12 that extends upward in a state of entering the inside is integrally formed at the upper end of the side plate 10, so that the upper end surface 10 a of the side plate 10 is uneven with respect to the lower engagement claw 12. It is in the shape. The lower engaging claw 12 is formed with an outwardly protruding flange 12a, and the upper and lower surfaces of the flange 12a are inclined.

  An inward lip 14 is formed on the inner surface of the left right side plate 10 with a slight gap from the lower engagement claw 12. For this reason, the inward lip 14 is formed between the lower engagement claw 12 and the inward lip 13. An inward groove 14 is formed. It is also possible to connect the opposing inward lips 13 together, and in this case, the reinforcing plate 11 may be omitted.

The display unit 2 includes a bowl-shaped outer cover 15 that opens upward, a first inner cover 16 that has a downward-opening bowl shape disposed so as to close the opening of the outer cover 15, and the first inner cover 16 and the outer cover 15. And a circuit board 18 disposed in a horizontal posture inside the second inner cover 17. The circuit board 18 includes a second inner cover 17 having a downward opening box shape disposed in a space surrounded by A group of light emitting diodes 4 is mounted (mounted). Then, in the present embodiment, the outer cover 15 the first and second inner cover 16, 17 and Deke over scan is configured.

  The outer cover 15 is an extruded product made of aluminum or aluminum alloy (and is therefore opaque). As basic elements, the left and right side plates 19 that are flush with the side plate 10 of the lower base 1 and both side plates are used. And a bottom plate 20 that connects the base plate 19 at the lower portion thereof, and the bottom plate 20 is placed (overlapped) on the upper end of the lower engagement claw 12 in the lower base 1. Further, an upper engaging claw 21 having an inward flange portion 21a is integrally formed at the lower ends of both side plates 19. The flange portion 21a of the upper engagement claw 21 has a lateral mountain shape whose upper and lower surfaces are inclined. For this reason, the outer cover 15 is attached to the lower base 1 in a one-touch manner by being pushed downward.

In this reference example, and the upper engaging claw 21 of the lower engaging claws 12 and the outer cover 14 of the lower base 1 constitutes the engagement means. In this reference example , when the outer cover 15 is pushed in, the side plates 10 of the lower base 1 are mainly bent and deformed so that the upper and lower engaging claws 15 and 21 are fitted (engaged).

A lower rib 22 is projected inwardly at a lower portion of the side plate 19 of the outer cover 15 with a slight gap from the bottom plate 20, and a substantially arc-shaped round groove 23 is provided between the bottom plate 20 and the lower rib 22. There while being formed, the upper end of the right and left side plates 19 have upper ribs 24 in the direction respectively are formed, further, it is middle rib 25 is formed on the upper and lower middle height position of the side plate 19.

(3). Internal structure The first inner cover 16 is manufactured by an injection molding method using a transparent resin (for example, polycarbonate resin) as a material, and is fitted between the upper rib 24 and the middle rib 25 of the outer cover 15. The left and right side plates 16a and a top plate that is flush with the top surface of the outer cover 15 are provided. The connecting portion between the side plate 16a and the top plate is a step 16b where the upper rib 24 of the outer cover 15 is fitted. It has become. A portion (opening groove portion) sandwiched between the upper ribs 24 of the outer cover 15 in the first inner cover 16 is a band-shaped light transmitting portion 3.

The second inner cover 17 is also manufactured by an injection molding method using a transparent resin (for example, acrylic resin or polycarbonate resin) as a raw material, and the left and right side plates 17a, the top plate connected to the upper end thereof, and the left and right side plates 17a and the top plate. It has a box shape having front and rear end plates 17b integrally connected to the plate and opening downward. The substantially upper half of the side plate 17a of the second inner cover 17 is in close contact with the inside of the first inner cover 16, and the lower half is fitted between the middle rib 25 and the lower rib 22 of the outer cover 15, Thus side plate 17a is has become stepped difference shape, the second inner cover 17 has a convex shape in front view as a whole.

Inside the second inner cover 17, two left and right foot pieces 17d extending downward from the top plate are integrally formed. The foot piece 17d is formed in a state of approaching to the outside and extends to the same height as the inner step surface 17c of the side plate 17a. The circuit board 18 is positioned by the inner step surface 17c and the foot piece 17b of the side plate 17a.

  The second inner cover 17 is filled with a transparent sealing agent 26 so as to enclose the circuit board 18 and the light emitting diode 4. To describe the filling method of the sealing agent, first, the fluid sealing agent is poured into the second inner cover 17 that is open upward to a depth slightly shallower than the inner stepped surface 17c, and then the light emitting diode 4 is directed downward. The circuit board 18 is fitted into the second inner cover 17 with the posture described above, and then the fluid sealant is poured for the second time so as to cover the circuit board 18.

  Since the 2nd inner cover 17 is formed in the box shape which has the end plate 17b, it can perform pouring of a fluid sealing agent without trouble. In addition, the second pouring of the sealing agent may be performed after the sealing agent poured in the first time is solidified, or the second pouring may be performed successively. In addition, since a load may be applied to the display device, the sealant 26 has some elasticity after being cured in order to prevent the circuit board 18 and the light emitting diode 4 from being damaged due to deformation. preferable. It is also possible to use an ultraviolet curable one as the sealing agent 26. In this case, there is an advantage that the curing time can be shortened.

  As shown in FIG. 4, the cable 6 is exposed from a portion near both ends of the circuit board 18. Cutouts 27 are formed at both front and rear ends of the bottom plate 20 of the outer cover 15 for drawing the cable 6 to the outside.

Since the display device is composed of a large number of display units 2, the end surfaces of the adjacent display units 2 overlap each other, and one side of the two display units 2 constituting both ends of the display device is located inside the foundation G or the like. Exposed. Then, end caps, and that overlap each other, the two shall be exposed to the inside or the like of the underlying G are prepared. For convenience, the former is referred to as an intermediate end cap and is denoted by reference numeral 5, and the latter is referred to as an endmost end cap and is denoted by reference numeral 5 ′.

  As shown in FIGS. 4 and 5, the intermediate end cap 5 has a rectangular portion in front view so as to overlap the portion of the end surface of the outer cover 15 excluding the upper engagement claw 21. A pair of left and right bosses 28 that enter the round groove 24 of the cover 15 and a foot 5 a that enters the inside of the lower base 1 are provided. An outward projecting portion 5b that fits into the inward groove 14 of the lower base 1 is integrally formed at the lower end of the foot portion 5a. The intermediate end cap 5 is made of a transparent resin.

  The intermediate end cap 5 is attached to the lower base 1 in the following procedure. That is, first, as shown in FIG. 5 (B), the intermediate end cap 5 is fitted into the lower base 1 in a posture extending in parallel with the lower base 1 in a plan view, and then the intermediate end cap 5 is rotated horizontally. The laterally projecting portion 5 b is fitted into the inward groove 14 of the lower base 1.

  The outermost end cap 5 ′ overlaps the entire end surface of the outer cover 15, and also includes a foot portion 5 a having a laterally extending portion 5 b. The outermost end cap 5 ′ is fixed to the outer cover 15 with a screw 29. The screw 29 is screwed into the circular groove 23 of the outer cover 15. The screw 29 is preferably a tapping screw.

Since both ends of the lower base 1 are exposed, the outermost end cap 5 ′ is fitted into the lower base 1 from the lateral direction. The outermost end cap 5 ′ is provided with a protrusion 5 c that partially enters the outer cover 15. Of course, it may be not projections 5c, conversely, an intermediate end cap 5 can be provided with a projection 5c (in this case, for example, by slightly reducing the length of the inner cover 16, 17 , It is necessary to allow the protrusion 5c to enter.).

(4) Assembling and construction As can be understood from FIG. 3, for example, when assembling the display unit 2, the circuit board 18 is mounted on the second inner cover 17 and the sealing material 26 is filled, and then sealed. The inner covers 16 and 17 are set on the outer cover 15 by inserting (inserting) the first inner cover 16 and the second inner cover 17 into the outer cover 15 from the ends. Either one of the inner covers 16 and 17 may be fitted to the outer cover 15 first, or both the inner covers 16 and 17 may be fitted in advance.

Depending on the processing error of the outer cover 15, the first inner cover 16 may be fitted into the outer cover 15 too tightly. Therefore, in this reference example , as shown in FIG. 3, the first inner cover 16 is formed in a tapered shape with a slight angle so that the interval (width) becomes narrower as it goes upward. When the inner covers 16 and 17 are fitted into the outer cover 15, a sealant can be applied to the gap.

  At the time of construction, first, the lower base 1 is laid on the foundation G, and then a group of display units 2 is mounted. As a method of attaching the group of the display units 2, for example, with the cables 6 of the adjacent display units 2 connected, the outer cover 15 of the first display unit 2 is attached to the lower base 1 by pushing it in from above, Next, the intermediate end cap 5 is fitted into the lower base 1 and then slid to fit into the circular groove 23 of the outer cover 15 in the first end cap 5, and then the outer cover 15 of the second display unit 2 is fitted. A method of attaching the display unit 2 in order from the end can be adopted by attaching the intermediate end cap 5.

Since the outer cover 15 of the display unit 2 can be slid while being attached to the lower base 1, a large number of display units 2 are attached to the lower base 1 in a state of being spaced from each other, and then the display attached to the lower base 1 It is also possible to bring adjacent display units 2 into close contact with each other by shifting the units 2. Between the end faces of adjacent display unit 2 the sealing agent may be applied to.

When the laterally projecting portion 5b is formed on the foot piece 5a of the intermediate end cap 5 as in the present reference example , the laterally projecting portion 5b functions as a retainer, and the laterally projecting portion 5b allows the left and right side plates 10 of the lower base 1 to be removed. the upper engaging claw 21 because it is prevented to leave from the lower engagement nails 12, the display unit 2 or lifted or whether et outside is lower base 1 by any external force but is prevented from being resiliently deformed inwardly There is an advantage that can solve the problem.

It is also possible to configure one display device with one display unit 2 without using the long lower base 1. In this case, the end cap 5 is fastened to the outer cover 15 with screws (in this case, the end cap 5 may be a vertically long rectangle covering the entire end surface of the outer cover 15). It is also possible to embed the display unit 2 in the braille block by setting the length of the display unit 2 to be the same as or substantially the same as the length of one side of the braille block (for example, 30 cm). Expose to the valley.) One of the display unit 2, this is the it is also possible to keep substantially attached to the lower base 1 of the same length.

(5). Specific Example of Control In this reference example , as schematically shown in FIG. 6, the light emitting diode 4 has three kinds of chips (three primary colors) of red light emission R, blue light emission B, and green light emission G. Chips R, B, and G are sealed with a glass layer. Then, light of any color (full color) can be generated by superimposing each color by controlling the intensity of red R, blue B, and green G and lighting. In addition, light intensity and blinking can be arbitrarily controlled. Therefore, for example, it is possible to change the emission color according to the environment, such as emitting colored light such as red or orange during the day and emitting white light at night. In addition to R, B, and G, a white diode chip can be arranged separately.

In addition, for example , the display device of this reference example is installed in parallel to the row of braille blocks on the platform of the station, the normal state is white, yellow when the train arrives, red when the train arrives, etc. Can be changed. Alternatively, it is possible to call attention by blinking the light emitting diode 4. Furthermore, for example, the light emitting diode 4 may have a different emission color for each unit, with one lower base 1 portion as one unit.

Further, when used as an emergency evacuation guidance display, the display device can be provided with a direction indicating function by turning on / off each light emitting diode 4 in order from the front to the front toward the evacuation route. Since the light-emitting diode 4 has low power consumption, it can be lit for a considerable time using a battery. Therefore, it can be said that this reference example is also excellent as an evacuation guidance device.

  Any one, two, or all of the first inner cover 16, the second inner cover 17, and the sealant 26 can be formed as a phosphorescent part. As a means for forming the phosphorescent part, for example, in the case of the inner covers 16, 17, there is a method in which a phosphorescent agent is kneaded with the raw material before molding and a phosphorescent agent-containing one is molded. In this case, it becomes a phosphorescent part of the inner covers 16 and 17. Another method is to apply a phosphorescent paint after molding. In this case, the surface (outer surface or inner surface or both surfaces) becomes the phosphorescent part. As a method for making the sealing agent 26 a phosphorescent part, it is preferable to incorporate a luminous agent into the raw material of the sealing agent 26. It is also possible to provide a member having a phosphorescent function in addition to the three.

(6). Implementation form
Next, the embodiment shown in FIG. 7 will be described. This embodiment is applied to a type for example you placed on the edge of the pavement and walkways. In this embodiment, the lamp includes a translucent cover 31 of the elongate formed in a cylindrical shape as a whole, which is configured as a substantially gutter-shaped base 3 2 and the main member Toritsui, these translucent cover 31 and the base 32 constitute the case described in the claims. Translucent cover 31 and the base 3 2 is long, for example, set to a length of 5 to 10 m (light-transmitting cover 31, it is also possible for example to a length of about 1m are connected by joints. ).

The translucent cover 31 is manufactured by an extrusion process using a transparent resin as a raw material, and is formed so that a pair of left and right feet 31a extends over the entire length. In addition, a substantially upward opening U-shaped auxiliary bracket 33 having left and right side plates 33a is disposed in close contact with the lower part of the inside of the translucent cover 31. The auxiliary bracket 33 is also an extruded product made of a transparent resin, and is provided with left and right lateral projections 34 and left and right downward projections 35, while the translucent cover 31 has a lateral projection of the auxiliary bracket 33. the inward projection 36 to hold the 34 upwardly immovable, and full upward groove 37 downward projection 35 is fitted so as not to left and right displacement of the support brackets 33 are formed, Accordingly, in the longitudinal direction of the translucent cover 31 It is held in a state that only deviates.

The upper end of the auxiliary bracket 33 is lower than the center of the translucent cover 31, and upper and lower holding grooves 36 ′ into which the circuit board 18 can be inserted are formed at the upper portions of the left and right inner surfaces. Holding groove 36 'is an example of the circuit board mounting portion. The outward projection 34 and the downward projection 35 of the auxiliary bracket 33, the inward projection 36 and the upward groove 37 of the translucent cover 31 are examples of fitting means for attaching the auxiliary bracket 33. The bottom of the auxiliary bracket 33 is flat.

Base 3 2 are extrusions of a light alloy such as aluminum, has a left and right side plates 32a and the bottom 32b, so full inside of the side plate 32a fitting the foot portion 31a of the translucent cover 31 ing. Then, while forming the engaging claw 38 to the foot portion 31a and below the translucent cover 31, the inner surface of the side plate 32a in base 3 2 form a engagement groove 39 engagement claw 38 is fitted The engaging claw 38 and the engaging groove 39 constitute engaging means described in the claims. In the present embodiment, it is also possible to express the engaging claws engaged with each other as a whole and the side plate 32a of the foot 31a and the base 3 2 of the translucent cover 31 (engaging means).

The side plate 32a of the base 3 2 to form a round groove 23 for attaching the end cap (not shown). Although not shown, the end cap is adapted to overlap the whole of the translucent cover 31 and the base 3 2, the lower surface is made flat to align with the lower surface of the base 3 2.

At the bottom of the base 3 2, a pair of left and right dovetail 40 which can be inserted the circuit board 18 is formed. Dovetail groove 40 is also an example of the circuit board mounting portion. Below the dovetail groove 40 is a groove opened upward, and cables can be put in this groove. The lower surface of the base 3 2, downward opening groove 41 for attaching the base 3 2 to a support member (not shown) is empty.

Base 3 2 in the present embodiment is basically a trough-like, Therefore, the left and right side plates 32a of the base 3 2 has easily deformed to fall outward. For this reason, even if the translucent cover 31 is long, it can be easily attached.

In the present embodiment , when the circuit board 18 is mounted in the lowermost dovetail groove 40, the light emitting diode 4 is hidden inside the base 32 and the light is diffused and irradiated toward the translucent cover 31, so the light emitting diode Even if the interval of 4 is increased, the integrity (continuity) of the light line can be secured. Therefore, it is suitable when not much illuminance is required.

If the circuit board 18 is provided on the translucent cover 31 (auxiliary bracket 33), the light emitting diodes 4 can be easily seen from the outside. The illuminance will inevitably increase. Therefore, it is suitable for installation in a place requiring high illuminance.

Although the portion corresponding to the auxiliary bracket 33 can be integrally formed with the translucent cover 31, if the auxiliary bracket 33 is configured separately from the translucent cover 31 as shown in the figure , the auxiliary bracket 33 is Since the dimensions are small and high processing accuracy can be ensured, there is an advantage that the holding groove 37 for mounting the circuit board 18 can be processed accurately.

The circuit board 18 has a length of several tens of centimeters. Therefore, when the holding groove 37 is integrally formed with the translucent cover 31, the circuit board 18 is pushed into the holding groove of the translucent cover 31 in order from the end. However, since the translucent cover 31 has a length of several m to 10 m in some cases, there is a possibility that the circuit board 18 cannot be inserted smoothly. However, the auxiliary bracket 33 is translucent as in the illustrated example. If it is configured separately from the cover 31, the group of circuit boards 18 may be mounted in advance on the auxiliary bracket 33 in an open state, and then the auxiliary bracket 33 may be inserted into the translucent cover 31. The circuit board 18 can be prevented from being damaged (the circuit board 18 may be damaged if the circuit board 18 is forcibly pressed, but the circuit board 18 is not damaged even if the auxiliary bracket 33 is pressed strongly).

The lamp can be attached to various places such as a building wall or fence, or a building ceiling. Accordingly, it is possible to change the arrangement posture as necessary, such as when the translucent cover 31 is turned sideways or turned downward . The circuitry board 18 is attached to a metal support plate, the support plate 'it is also possible, such as plugging in or dovetail groove 40, in this case, the holding groove 36' of the retaining groove 36 integrally to the translucent cover 31 Even if molded, the circuit board 18 can be mounted without being damaged.
