DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting diode protector which is suitably used for a road stop line, a vehicle guidance line, and the like in night road construction and inside a tunnel.

[0002]

2. Description of the Related Art For example, road security members such as car stop lines and vehicle guide lines are used in nighttime road construction. Some of the traffic stop lines are band-shaped rubber mats painted with white reflective paint, which are temporarily installed on the road surface in a transverse state.
As road security equipment such as vehicle guidance and warning lights, there is one in which a plurality of light emitting diodes (LEDs) are arranged inside a flexible tube, and this is used by being laid on a fence or a barricade.

[0003]

However, a traffic stop line in which a white reflective paint is applied to a rubber mat emits light when hit by headlights, but is hardly seen by a driver and has a poor visual effect. The one in which a plurality of light emitting diodes are arranged inside a flexible tube, when crawling on the road surface,
Light emitting diodes are easily damaged when stepped on by a vehicle.

An object of the present invention is to provide a light-emitting diode protector which can be suitably used as a traffic stop line, a vehicle guidance line, a road marking, etc., which has excellent visibility.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a light emitting diode protector that can prevent the destruction and damage of a light emitting diode due to vehicle tread pressure. An object of the present invention is to provide a light-emitting diode protector having a drip-proof and rain-proof structure. An object of the present invention is to provide a light emitting diode protector having excellent adhesion to a road surface.

[0005]

The light-emitting diode protector of the present invention comprises a protector body 1 made of a translucent material, and a light-emitting diode 2 built in the protector body 1. The protector body 1 has a mountain-shaped cross section having a mountain-shaped upper surface 3 and a flat grounding bottom surface 4 and is formed in a belt-like shape, and a through hole 5 of the light-emitting diode 2 is formed in the longitudinal direction near the center of the cross-section. You. A plurality of light emitting diodes 2 are arranged in the through hole 5 in the longitudinal direction. The protector body 1 can have a non-slip ridge 6 formed integrally on the chevron upper surface 3 in the longitudinal direction thereof, and a concave groove 7 formed on the ground bottom surface 4 in the longitudinal direction thereof. The through hole 5 is preferably formed to have a circular cross section.

[0006]

According to the light emitting diode protector having the above structure, the light emitted from the light emitting diode 2 passes through the inside of the protector body 1, is refracted by the chevron upper surface 3, and then reflected. When the light emitting diode 2 is turned on and off, the visibility can be further improved. Since the light emitting diode 2 is covered and protected by the protector body 1, even if a vehicle passes over the protector, the light emitting diode 2 is not broken or damaged, and drip-proof and rain-proof properties can be secured.

[0007] The anti-slip ridge 6 prevents the vehicle from slipping when traveling on the chevron top surface 3. Since the grounding bottom surface 4 of the belt-shaped protector body 1 is formed flat, the protector body 1 can be stably grounded on the road surface by its own weight. When the concave groove 7 is provided on the grounding bottom surface 4 of the protector body 1, the concave groove 7 locally deforms as the vehicle passes, reduces the internal pressure, and exerts a suction cup function of attaching to the road surface, This protector does not lift or jump off the road surface, and the degree of adhesion to the road surface is increased. The concave groove 7 has a function of refracting light emitted from the light emitting diode 2 and also has a function of preventing slipping on a road surface.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a light emitting diode protector according to the present invention will be described with reference to FIGS. This light-emitting diode protector is provided inside a transparent protector body 1 formed in a belt-like shape with a mountain-shaped cross section.
A plurality of light emitting diodes 2 are arranged in the longitudinal direction. The protector body 1 is made of a transparent or translucent (including colored transparent, translucent colored) synthetic resin such as soft vinyl chloride or a soft material such as synthetic rubber, and is formed in a mountain shape having a low cross-sectional shape. And a flat grounded bottom surface 4, and a through hole 5 through which the light emitting diode 2 passes is formed in the center of the cross section in a longitudinal direction thereof. The through hole 5 is formed to have a circular or semicircular cross section or a shape close thereto in order to make the through hole 5 difficult to be crushed even when a treading load of the vehicle is applied.

Both slopes 3a on the upper surface 3 of the protector body 1
A plurality of anti-slip projections 6 are integrally formed on the slightly flat top 3c and the slightly flat top 3c in parallel with the longitudinal direction to prevent slip of the vehicle. Two recessed grooves 7.7 are formed on the widthwise middle portion of the grounding bottom surface 4 of the protector body 1 so as to be located on both lower sides of the through hole 5, and two portions are also formed on the widthwise end portion of the grounding bottom surface 4. Groove 7.7
Are formed in a rectangular cross section and parallel to the longitudinal direction.
The depth d ₁ of the concave groove 7 at the widthwise intermediate portion of the grounding bottom surface 4 is approximately half of the height H of the peak of the protector body 1, and the depth d ₂ of the concave groove 7 at the widthwise end portion is the concave groove 7. Is set to approximately half of the depth d ₁ of

Specifically, for example, the length L of one protector body 1 is 2 to 10 m, and the width W of the grounding bottom surface 4 is 10
The peak height H is set to 20 mm. The spherical diameter of the light emitting diode 2 is 6 mm, while the diameter of the through hole 5 is 8 mm
And Depth d of concave groove 7 at widthwise intermediate portion of grounding bottom surface 4
₁ is 10 mm, and the depth d ₂ of the groove 7 near the widthwise end is 5
mm, and the inner bottom width a of each groove 7 is set to 8 mm.

A plurality of light-emitting diodes 2 of a high-brightness flashing type are connected in parallel with a power source 9 such as a battery, and are arranged in the through hole 5 of the protector body 1 at a predetermined interval in the longitudinal direction. An electric wire 10 connecting the light emitting diodes 2 is led out from one end of the through hole 5 and connected to a power source 9 such as a battery. At this time, in order to prevent water from entering the through hole 5, one end of the through hole 5 from which the electric wire 10 is led out and both ends of the other end are sealed with a waterproof sealing material or the like.

The light-emitting diode protector having the above-mentioned configuration is installed on a road stop line on the road surface S so as to cross the road at night or during road construction in a tunnel, or on the road surface S obliquely crossing the road. It is used for vehicle guidance lines. In addition, it can be permanently installed on a road shoulder or the like as a road marking body. When the power supply 9 is turned on in this installation state, the plurality of light emitting diodes 2 in the transparent protector body 1 blink, and the light emitted from each light emitting diode 2 is reflected after being refracted on the chevron upper surface 3, and furthermore, has a concave groove. After being refracted by the inner surface of 7, the light is reflected. The reflected light exerts visibility and brightness over the entire length of the protector body 1, and effectively exerts a traffic stop function, a vehicle guidance function, or a road marking function on the road surface.

Even if the vehicle accidentally steps on the light emitting diode protector, the light emitting diode 2
Is protected by a thick portion having the strength due to the hardness of the material of the protector body 1, so that it is not broken or damaged by the treading load of the vehicle, and the electric wire 10 does not break. In particular, when the through hole 5 is formed in a circular or semi-circular cross section or a shape close thereto,
Even when a vehicle load is applied, the through hole 5 is hardly crushed by the strength of the material hardness of the protector body 1 and the use of the arch action, so that a space for accommodating the light emitting diode 2 can be secured, and the light emitting diode 2 is advantageous in preventing breakage and damage. Becomes Also, the concave groove 7 of the protector body 1 accompanying the passage of the vehicle.
Is locally deformed to reduce the internal pressure and adhere to the road surface S, so that the protector body 1 does not rise or jump off the road surface S. For safer and more secure fixing to the road, it is preferable to fix the end of the protector body 1 on the road surface S with a fastener 11 such as a concrete nail.

The cross-sectional mountain shape of the protector body 1 can be changed to a triangular shape, a semicircular shape, or other shapes close to these shapes, instead of the low mountain shape shown in the illustrated example. The light emitting diode 2 is preferably a blinking type in order to enhance visibility, but is not limited to this. When the protector body 1 is formed of a soft material such as soft vinyl chloride, the elongated light-emitting diode protector can be wound into a roll and is easy to carry, but is formed of a hard resin such as hard vinyl chloride. It may be.
