Description

Sign board for showing the traffic information}

The present invention relates to a road traffic sign, and more specifically, by constructing a swan lighting using a custom-type fluorescent lamp to improve the identification of the road traffic sign to improve road driving conditions during snow, rain, fog, and night driving and to generate accidents. The present invention relates to a road traffic sign that can prevent power loss and reduce power consumption.

The road traffic sign is installed on the road to inform the driver of the direction of travel and the speed limit. Especially for drivers on the road, it is important to inform the geographic situation.

1 is a front view of a road traffic sign 10 conventionally used. Road traffic signs are commonly used in the form of letters and / or figures printed on the surface of metal plates. This type of road traffic sign can be identified to some extent during the day, but when night, snow, rain, or fog, the identification power is remarkably degraded, and thus it does not serve as a guide.

In order to improve this disadvantage, Utility Model Registration Application No. 2000-0017346 filed on June 19, 2000 "lighting signs for lighting" is disclosed. The road traffic sign 10 ′ disclosed in the utility model application is referring to FIG. 2: a main frame 18 having an empty rectangular frame shape and fixed to the support bar 16; Auxiliary frames 20 and 22 of the same shape and size which are installed to be opened and closed by hinge means such as hinges on both open sides of the main frame 18; A light emitting body (not shown) seated on horizontal beams fixed to both inner sides of the main frame 18 and connected to an external power supply so as to be turned on and off; A main and auxiliary flanges protruding in a 'U' shape along a surface edge where the main and auxiliary frames are in contact with each other; Removably installed so as to seal the open side of the opposing side auxiliary frame formed with the auxiliary flange, the road sign is displayed on one side and the other side, such as publicity, advertising, policy guidance of national and local governments, commercial advertising, It is configured to include a marker 24 made of a cloth material that can display the pattern. Reference numeral 12 is a base and 14 is a prop.

The lighting road sign configured as described above can easily recognize the sign 24 made of fabric material from the front by using the light emitting body installed therein, thereby improving the discriminating power compared to the road traffic sign 10 shown in FIG. 1. to provide. However, since the illuminance of the light emitting body installed on the road traffic sign decreases as time passes, the discriminating power of the sign is reduced. In addition, since the light emitter does not have a uniform luminance uniformity even in a normal illuminance state, a dark portion is generated in the marker part 24, which causes a problem that cannot be identified. In order to solve this problem, it is possible to increase the number of installation of the luminous material, but the disadvantage is that the cost is increased. Moreover, in order to replace the luminous material, there was an inconvenience such as having to solder again.

The present invention is to solve the above problems, the object of the present invention is to construct the luminescent light using a tubular fluorescent lamp to improve the identification of the road traffic signs to improve the road driving conditions during snow, rain, fog, night driving It is to provide road traffic signs that can prevent accidents and reduce power consumption.

Another object of the present invention is to provide a road traffic sign that can improve the durability of the lighting device used under the adverse conditions of the outdoor and easy to replace the workability.

As shown in FIG. 2, the road traffic sign 30 according to the present invention has a display portion 35 positioned on the surface thereof, and a frame 34 for supporting and fixing the display portion 35 is formed. Inside, a plurality of capillary fluorescent lamps (not shown) are used, which are used as the backlight of the display unit 35.

In particular, the frame according to the present invention has a very thin thickness than the conventional frame because it uses a tubular fluorescent lamp. Although not shown in detail, the frame 34 may rotate or detachably fix the portion of the front plate 32 to which the display unit 35 is attached by using a hinge (not shown) on the side. The display unit 35 is preferably made of a waterproof cloth material or plexiglass.

In addition, although not shown, a reflector may be installed to efficiently use the light emitted from the fluorescent lamp 36, and a diffuser may be installed to uniformly emit light.

A state in which the front plate 32 including the display portion 35 is separated from the frame 34 by using the hinge is shown in FIG. 4. Inside the frame 34, a plurality of tubular fluorescent lamps 36 are arranged in parallel. In addition, a fixing case 38 for fixing the tubular fluorescent lamps 36 arranged in parallel is provided. In addition, the fixed case 38 is provided with a power supply member 40 for electrically connecting the electrode 36a of the fluorescent lamp 36.
