The present invention relates to an information display device.

[Conventional technology]

Conventionally, as such an information display device, an incandescent light bulb or the like arranged behind a display portion formed of a plurality of arrow symbols directed in a predetermined direction such as a rightward direction or a leftward direction to indicate a detour direction or the like is formed. There is used a structure in which the light source of (1) is sequentially turned on or blinked for display.

In addition, as shown in FIG. 9, a conventional road information panel 50 for displaying road construction or various road information is provided with a main display section 51 for displaying predetermined information at night or at dusk. A structure in which a light source (not shown) is housed in a device casing 52 that constitutes the display unit 51 and is turned on as appropriate is often used. Further, if desired, a sub-display section 53 such as a zebra mark related to the display content is attached around the main display section 51, and one or more red or yellow colors are provided on the top of the road information board 50. A device equipped with a rotary indicator 54 for emitting light is also used.

[Problems to be solved by the device]

However, even the road information board consisting of the arrow signals indicating the detour direction only enables the display in either the left or right direction, and not only lacks the commonality as an information display device. However, it has a problem that it is difficult to connect to a vehicle power source because it consumes a large amount of power.

Further, the sub display portion 53 formed around the main display portion 51,
The structure is such that it is simply drawn or attached to the surface of the equipment casing 52. When only the rotation indicator light 54 is turned on, there is a problem that the driver of a vehicle running at a high speed lacks visibility and causes a rear-end collision accident.

The present invention has been made in view of the above problems, and by using a light emitting element such as a light emitting diode as a light source, it can be connected to a vehicle power source for power saving and convenient use, and can be used on an appropriate road. An object of the present invention is to provide a small-sized information display device that can be detachably attached to the surface of a body forming an information board or a vehicle body to improve the visibility of the road information board.

(Means for Solving the Problems) In order to achieve the above object, an information display device according to the present invention forms a lamp chamber by sealing a front lens opening of a machine casing with a surface lens, and a predetermined lamp chamber is formed in the lamp chamber. A substrate for arranging a plurality of light emitting elements is arranged on one or more display portions having a shape, and a light shielding plate is provided by punching a portion corresponding to each of the light emitting elements, and the light shielding plate is the surface lens. Configured close to
And the light emitting element is arranged in each of the perforated portions, and the gist is that all or part of the light emitting element for each display unit can be turned on or blinked all at once or sequentially. The information display device can be configured by forming the display portion with an arrow symbol that indicates both left and right directions and arranging a plurality of light emitting elements on each display portion.

In addition, a front lens is attached to a front opening of a container casing having a front shape formed in a predetermined shape corresponding to all or part of a sub display portion formed around the main display portion to form a lamp chamber. , A suction structure is formed on the back side of the housing, and a light emitting section equipped with a plurality of light emitting elements arranged in a predetermined array is provided inside the lamp chamber so that the light emitting section can be turned on or blinked appropriately. Further, the upper edge of the above-mentioned housing is formed so as to project forward, and is formed so as to form an inverted triangle in a side cross-sectional shape, and the array of a plurality of light emitting element groups is sequentially projected from the top to the bottom with respect to the substrate surface. It is also possible to install so as to reduce

[Action]

Thus, according to the structure of the information display device according to the present invention, if desired, the information display device is attached to the surface of the cabinet of the road information panel or the surface of the vehicle body to display the lights simultaneously or sequentially, or to turn on / off the lights of other vehicles. It is possible to improve the visibility of information display for persons and the like. In particular, the light-shielding plate formed by arranging each light-emitting element is provided with a light-shielding plate to improve the contrast when the light-emitting element is turned on and to improve the visibility of the display unit. Further, the light-shielding plate has a tip extension portion projecting toward the front of the head of the light emitting element group, which serves as an eave for each light emitting element, and has a function of preventing pseudo lighting against external light emitted from a predetermined height.

Further, in the structure in which the upper edge of the casing is projected to the front surface of the surface lens, the effect of preventing snow accretion and surface reflection on the surface lens is exerted, and the cause of deterioration of visibility is reduced.
