Description

Dual Light Traffic Signs {DUAL RADIATION TRAFFIC SIGN}

The present invention relates to a dual-luminescent traffic sign, and more particularly, by forming the retroreflective sheeting to make a specific traffic sign, when the light emitted from the vehicle is irradiated to the retroreflective sheeting, it is reflected by the retroreflective sheeting and the specific traffic When the display is indirectly emitted and at the same time, a plurality of holes are drilled in the retroreflective sheeting paper and the like so that the light is irradiated through the plurality of holes by the lighting means installed therein so that the light from the vehicle is not directly irradiated on the retroreflective sheeting paper. By configuring the light irradiated by the lighting means to emit light directly through a plurality of through holes perforated in the retroreflective sheeting, for example, whether the vehicle headlight light is directly irradiated on the traffic sign, the traffic sign is doubled by the driver. Dual light traffic signs that can be identified on the back It relates.

In general, road signs and road guide signs are installed near road sections and intersections. These road guide signs are installed on the side of the elbow support to hang the metal plate on which the road guide letters or symbols are installed, the road guide letters on the road guide signs are constructed by bonding high-brightness reflective sheet paper.

Therefore, when the vehicle's lighting is irradiated on the road sign at night, the high-brightness reflective sheet reflects and scatters the light irradiated from the vehicle so that the driver can easily recognize the road guidance.

However, in the conventional reflective road signs, when the vehicle headlights are not directly irradiated with the road signs or condensation occurs such as dew or moisture on the half-seat sheet, foreign matter such as dust forms on the reflective sheets. In the case that the reflector is contaminated by contaminating the reflective sheet significantly, or the direction of irradiation of the car headlight and the road sign do not coincide depending on the shape or ups and downs of the road on which the road sign is installed, the driver may properly adjust the road sign. There was a problem that can not read the exact road guidance information can not read. This is because the guide letters on the road signs do not emit light on their own, but receive and reflect light beams from the vehicle until the driver can read the road guide letters.

Due to such a problem, a recent trend is to develop a road sign that emits light instead of a road sign that can be reflected by the illumination of a vehicle. However, in the case of the self-luminous road sign, the road sign is installed outdoors, so that a separate waterproofing process is required, such as molding, so that the manufacturing cost increases and the thickness of the sign by the lighting means installed therein. There was a problem that the thickened to damage the beauty of the street.

Accordingly, the present inventors form a specific traffic sign using the retroreflective sheeting paper, and at the same time, a plurality of holes are drilled in the retroreflective sheeting paper and the frame to which the sheeting sheet is attached, and the lighting means mounted therein is provided. By allowing light to be emitted, the visibility and identification of traffic signs are always increased at long distances and near distances, regardless of whether the vehicle lights are directly irradiated on traffic signs. It has led to the development of a double light traffic sign having a waterproof frame structure that cannot penetrate by means.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 is an exploded perspective view of a dual light traffic sign according to an embodiment of the present invention.

Referring to FIG. 1, a dual light emitting traffic label according to an exemplary embodiment of the present invention includes a front frame frame 10a having a cutout 12 formed to form a specific traffic sign (eg, an arrow, etc.), and the front frame frame 10a. Rear frame frame 10b coupled to each other to form a receiving space therein, disposed on a rear surface of the front frame frame 10a and attached to correspond to the cutout 12, and a plurality of through holes 22 The retro-reflective sheet paper 20 which is continuously perforated, the transparent panel 30 which is attached to correspond to the rear surface of the retro-reflective sheet 20, and prevents rainwater or contaminants from penetrating from the perforated through-hole 22 and the It is provided on the inner side of the rear frame frame (10b) consists of a lighting means 40 for emitting light by emitting light toward the cutout portion 12 side of the front frame frame (10a).

The front frame frame 10a cuts the center thereof to form a cutout 12 that forms a traffic sign of various shapes, for example, an arrow, a u-turn sign, and a direction sign. Preferably, a retroreflective sheet paper having a different color from the retroreflective sheet paper 20 disposed to correspond to the cutout 12 may be further provided in an area not cut in the front frame frame 10a. Of course, it is obvious that a paint or the like having retroreflective properties can be applied. Further, although the drawings of the present specification are described with reference to the circular type traffic signs, those skilled in the art will understand that the same can be applied to traffic signs of various shapes such as triangle and square types.

The rear mold frame 10b is coupled to the front mold frame 10a to form an accommodation space therein. For example, it can be firmly fastened with each other using a bolt or the like.

The retroreflective sheeting 20 is disposed on the rear surface of the front mold frame 10a and is attached to correspond to the cutout 12. In this case, the plurality of through holes 22 are continuously drilled in the retroreflective sheeting 20. Therefore, the retroreflective sheeting 20 disposed behind the front frame frame 10a is exposed forward in the same shape as the cutout 12 cut into a specific traffic sign. Therefore, when the light irradiated from the vehicle is irradiated on the retroreflective sheeting paper 20 of the dual-light traffic sign, it is reflected by the retroreflective sheeting 20 to cause a specific traffic sign to indirectly emit light. On the other hand, the lighting means 40 is installed on the inner surface of the rear frame frame 10b, the light irradiated by the lighting means 40 is directed toward the cutout portion 12 side of the front frame frame (10a). As a result, even when the vehicle lighting is not directly irradiated to the retroreflective sheeting 20, the light irradiated by the lighting means 40 is passed through the plurality of through holes 22 perforated in the retroreflective sheeting 20. By direct light emission, certain traffic signs made of cutouts can be identified twice.

As such, by providing a plurality of through holes in the retroreflective sheeting 20 forming a specific traffic sign, the visibility and identification of the traffic sign can always be increased at a distance and at a short distance regardless of whether the vehicle lighting is directly irradiated on the traffic sign. .

The transparent panel 30 is attached to the rear surface of the retroreflective sheeting 20 and prevents water or contaminants from penetrating through the perforated holes. In addition, the transparent panel 30 also has a function to allow the light emitted from the rear side to partially emit light while passing through the transparent panel 30 to emit light uniformly.

As shown in FIG. 1, the luminaire 40 has a structure in which a plurality of LEDs 44 are continuously arranged on a PCB substrate 42. Preferably, the light emitting module consisting of a PCB substrate and LED can be manufactured in a modular manner, and a plurality of modular lighting means can be arranged on the inner side of the rear frame frame. For example, a plurality of modular lighting means consisting of squares or rectangles are provided so as to face the specific traffic sign. This eliminates the necessity of separately manufacturing PCB boards corresponding to the various traffic marking shapes to be displayed, and it is possible to arrange a plurality of modular luminaires in the rear frame frame to correspond to various types of traffic signs, thereby simplifying the manufacturing process and manufacturing. Cost can be reduced.

Such lighting means 40 is to be installed on the inner surface of the rear frame frame, preferably, the lighting means 40 is installed to protrude to the inner surface of the rear frame frame is a storage frame (the receiving recess is formed therein) ( 14) It is inserted and mounted inside. As a result, even if rainwater or the like flows into the mold frame, the lighting means 40 enclosed by the storage frame 14 is secured and waterproof from rainwater.

More preferably, while supporting the lighting means 40 in the storage frame, a support member for maintaining a predetermined distance between the transparent panel 30 and the lighting means 40 ( 50) may be further provided. Since the support member 50 maintains the lighting means 40 and the transparent panel 30 at a predetermined interval, the light irradiated by the lighting means 40 is irradiated to a wider area of the transparent panel 30. As a result, surface luminescence is more effectively transmitted through the transparent panel 30.

2 and 3, the front frame frame 10a is provided with a stepped portion 14 bent to form a c-shape along its edge. Therefore, the groove 14 is formed in the stepped portion 14, and the rainwater penetrated from the outside is discharged along the grooved portion 16 of the stepped portion 14. As a result, even if a portion of rainwater is introduced through the interlocked front and rear frame frames, the introduced rainwater is blocked by the step 14 and is discharged downward along the recess 16.

4 is an exploded perspective view of a dual light traffic sign according to another embodiment of the present invention.

Referring to FIG. 4, the dual light emitting traffic sign according to another embodiment of the present invention is formed such that the retroreflective part 122 forms a specific traffic mark, and a plurality of through holes 122 are continuously formed in the retroreflective part 122. The front frame frame (110a) which is perforated in the form, the rear frame frame (110b) is coupled to the front frame frame (110a) to form a receiving space therein, the retroreflective portion 122 of the front frame frame (110a) It is attached to the rear side and is installed on the inner side of the transparent panel 130 and the rear frame frame (110b) to prevent rain water or contaminants from penetrating from the perforated through hole to emit light by emitting light toward the front frame frame side Including the lighting means 140, when the light irradiated from the vehicle is irradiated to the retroreflective sheet portion 122, it is reflected by the retroreflective portion 122 to indirectly emit a specific traffic sign, the vehicle When the light from the direct reflection unit 122 is not directly irradiated, the light emitted by the luminaire 140 emits light directly through the plurality of through holes 122 perforated in the retroreflective unit 120 In this case, the specific traffic sign composed of the retroreflective part 122 is characterized in that it is identified twice.

In the present embodiment, unlike the above-described embodiment, a specific traffic sign is formed by using a retroreflective sheeting paper or the like on the front of the front frame frame 110a without cutting the front frame frame to form a traffic sign. There is a technical feature in that a plurality of holes 122 are punched only in the retroreflective portion 122 having the marking. In such a structure, a cutting process for forming an incision is omitted, and a retroreflective sheet paper is attached to the retroreflective sheeting sheet without any perforation, and then the front frame frame itself is drilled to simplify the manufacturing process. And, as a result, there is an advantage that can lower the manufacturing cost.

Although the present invention has been described in detail with reference to the accompanying drawings, the present invention is not limited to such a specific structure. Those skilled in the art will be able to variously modify or change the embodiments of the present invention without departing from the spirit and scope of the present invention as set forth in the claims below.
