Description

Cold light traffic sign structure

This creation is about a traffic sign, especially a cold light traffic sign structure that regulates road traffic and has a luminous function.

According to the general road signs, traffic signs will be used to indicate, warn, prohibit, etc. The traditional traffic signs are provided with text or graphics on a substrate. At night, the lights of the vehicles illuminate the substrate. When reflecting, the driver can see the text or pattern on the substrate. However, because the height of each car is different, the angle of incidence and the angle of reflection of the light on the substrate are also different. If the weather is not good, it is easy to cause the driver. The text or pattern on the substrate cannot be reliably identified, so the traditional traffic sign cannot perform a good indication at night or when the weather is not good.

In order to improve the lack of the above-mentioned traditional traffic signs, some people design a illuminable traffic sign, as shown in the first figure, which is a conventional illuminable traffic sign, which is provided with a text or a pattern on a substrate 10. 20, and a plurality of LED illuminators (light emitting diodes) 30 are embedded on the substrate 10 to achieve the effect of illuminating. However, the conventional illuminable traffic sign requires a preset shape on the substrate 10. The plurality of perforations are arranged for the LED illuminator 30 to be embedded and combined, so that not only the construction is inconvenient, the man-hours are labored, the manufacturing is high, and the failure rate is high. When the single LED illuminator 30 is damaged, the text or the pattern is easily generated. The situation of identification.

There is also a conventional illuminating traffic sign, such as the Chinese Patent Publication No. CN101777292A "LED surface illuminated road traffic sign", which uses a LED illuminator (light emitting diode) disposed on the circumference side to project a light source toward the center. The light guide plate is used to evenly reflect the light, but the method is only suitable for the traditional light box mode (no reflection effect at night, the surface layer only uses the acrylic plate) thickness is too thick, and the LED illuminator is provided by the peripheral edge, so the size If it is larger than the illumination range of the light, and the overall illumination warning function is greatly reduced, the applicability is not high, and the volume is large, and the manufacturing cost is too high.

In view of the shortcomings of the above-mentioned conventional illuminating traffic signs, the creator has launched the creation with the idea of designing and testing, and after many revisions and improvements.

The present invention provides a cold light traffic sign structure comprising: a substrate, a luminescent plate, a reflective film, and a graphic layer, wherein the substrate has a front surface and a back surface opposite to the front surface, and the luminescent panel is The light source for driving the light is set to be the same as the shape and size of the substrate, and is fixed on the front surface of the substrate. The reflective film has a reflective and light transmissive effect, and is disposed in the same shape and size as the cold light plate. On the cold light plate, the reflective film has a single color traffic frame or a bottom color layer, and the graphic layer can be a traffic text or a pattern, and is disposed on the reflective film; thereby, the traffic sign can be made The card produces the indications, warnings, and prohibitions of daytime nighttime reflections and active illumination.

The main purpose of the present invention is that the cold light plate is fixed on the substrate, the reflective film is attached to the cold light plate, the construction is convenient, and the overall traffic sign size is ultra-thin, and the failure rate is low. low.

The second purpose of this creation is that it uses a cold light plate as a light source, so that regardless of the size of the traffic sign, a uniform illumination effect can be produced, the size of the product is not limited, and the brightness of the light source is uniform.

Another purpose of this creation is that it can pre-fabricate the modular semi-finished products of the substrate combined with the cold light plate and the reflective film, and then paste the specified graphic layer according to the customer's requirements, to achieve a single specification stock convenient, and the product productivity efficiency is improved. The convenience of manufacturing is improved.

A further object of the present invention is that the cold light traffic sign is ultra-thin in size, so that when the cold light plate, the reflective film or the graphic layer is damaged, a new cold light plate, a reflective film and a graphic layer can be additionally attached to the original surface layer. Continue to use, so the product is more suitable and durable.

Please refer to the second, third, fourth and fifth figures. The present invention provides a cold light traffic sign structure comprising: a substrate 1, a cold light plate 2, a reflective film 3 and a graphic layer. 4, wherein the substrate 1 has a front surface 11 and a back surface 12 opposite to the front surface 11, the cold light plate 2 is mainly formed by arranging luminescent powder between two transparent electrode sheets (which may be glass sheets or plastic sheets, etc.) a light source that can be driven by electric power, and the cold light plate 2 is disposed to be the same shape and size as the substrate 1, and has a bonding surface 21 and a light emitting surface 22 opposite to the bonding surface, and the bonding surface 21 is attached to the front surface 11 of the substrate 1 and is fixed. The reflective film 3 is a PVC film having a reflective and light transmissive effect by optically reflecting light, and is disposed in the same shape and size as the cold light plate 2 The adhesive or coating adhesive is attached to the light-emitting surface 22 of the cold-light panel 2, and the reflective film 3 has a single color traffic frame 31 or a ground color layer. Printing or pasting is disposed on the reflective film 3, and the traffic map of this embodiment 3 is a triangle, and may be a circle or other shape, and is not limited to a triangle.
