Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sign device that uses LED lamps to display various indications.

[Conventional technology and problems]

BACKGROUND ART Conventionally, for example, a red board with arrows displayed using white reflective paint or the like has been generally used as a guide sign during road construction work, traffic accident handling, etc.

However, such traffic signs are usually composed of relatively large and hard boards, so
It is inconvenient to carry, and the display, in this case the white arrow, is made of reflective material such as reflective paint, so when it is hit by light from a car headlamp, for example, it reflects the light and is easily visible. However, in the case of pedestrians and bicycles,
Furthermore, in the case of a car with a malfunctioning headlamp, it may not illuminate the traffic sign, and in such cases, the traffic sign does not reflect light and is difficult to see, resulting in safety concerns. There was a problem with sexuality.

[Purpose of invention]

In view of the above points, the present invention aims to provide a highly safe sign device that is easy to carry, has good visibility, and is easy to carry.

[Means and actions for solving problems]

According to the present invention, the above purpose is to provide a flexible sheet, a plurality of LED lamps fixedly arranged as appropriate on the surface of the sheet, a backing sheet arranged on the back side of the sheet, and a flexible sheet. A protective cover consisting of a transparent sheet disposed on the front side and a waterproof sheet disposed on the back side of the sheet and formed to surround the sheet, and a protective cover formed to surround the sheet and the sheet and the back side for lighting the LED lamp. The drive circuit is connected to each LED lamp through the sheets, and the portion of each LED lamp exposed on the back side of the sheet is covered with a flexible member. This is achieved by an LED display type sign device configured such that the back side of the member is glued to the front surface of the back sheet, and the top surface of the LED lamp substrate that abuts the back surface of the sheet is also glued.

According to this invention, since the entire device basically consists of a flexible sheet and a protective cover, it is possible to attach this sheet to a curved surface when in use, and also to not use it. If necessary, it can be rolled up, making it easier to carry and requiring less space for storage. Moreover, since the predetermined pattern is displayed using LED lamps, the visibility of the display is greatly improved.
Improves safety.

Furthermore, since the connection lead wires to each LED lamp are protected by the back sheet and fixedly held by a flexible member on the back side of the LED lamp, the protective cover etc. can be placed on the back side of the LED lamp during use. Even if the LED lamp is hit or rubbed, the connection lead wires on the back side of the LED lamp will not be cut, they are protected by the flexible member, and the connection lead wires are protected by the backing sheet. Since the back sheet is covered and protected and is fixed to the back side of each LED lamp via a flexible member, the sheet will not wrinkle. In addition, since LED lamps are used as light emitters, power consumption is significantly reduced compared to using incandescent light bulbs, and there is also less heat generation, which prevents the protective cover from burning or melting due to heat. There's nothing to do.

Each of these is constructed by attaching one to a plurality of (four in the illustrated case) LEDs 22 to the upper surface of the substrate 21, and is inserted from the back side into a through hole provided along the outline of the display 12 on the sheet 11. each
An LED 22 is attached to protrude from the front side of the sheet 11.

Note that each LED lamp 13 is preferably covered by one cap 23 that can accommodate all the LEDs 22 as shown by the chain line, so that it can be observed like one light bulb.

Furthermore, the LED lamp 13 is connected to the sheet 11.
The lead part of the LED 22 protrudes from the part exposed on the back side of the board 21, that is, the bottom surface of the board 21, and the connection lead wire from the drive circuit (not shown) is connected to the bottom surface of the board 21. A flexible member 24 made of a flexible material such as plastic is attached using an adhesive or the like. This prevents the lead wires connected to the LED 22 from breaking or coming off the lead portion of the LED 22 during use. In addition, LED22
The peripheral portion where the substrate 21 contacts the back surface of the sheet 11 is also attached with an adhesive or the like.

Here, the back surface of the flexible member 24 is adhered to the surface of the back sheet 11' or the surface of the waterproof sheet 15 when the back sheet 11' is not used, using an adhesive or the like. each
Since the connection leads to the LEDs 22 are protected between the sheet 11 and the back sheet 11', and the back sheet 11' is fixed to the sheet 11 only at the position of each LED 22, There is no wobbling or loss of flexibility of the sheet 11.

The transparent sheet 14 is surrounded by a waterproof sheet 15
The protective cover 16 is covered by a folded portion around the periphery of the protective cover 16 and is formed into a bag-like shape by sewing, gluing, fusing, etc. in a liquid-tight manner. This results in
