Description

Detailed Description of the Invention

The present invention relates to a cable with a light emitting unit for use in night construction, a display or the like.

When construction is carried out on the road at night, it is obliged to install a security light that clearly indicates the construction site for vehicles and pedestrians to pass. In general, night work is made up of self-illuminating color cones arranged at regular intervals in the corresponding places. Conventionally, an illumination method for a self-illuminating color cone is generally a method in which an incandescent bulb is placed in the color cone and a power supply of AC 100V is wired to each. In addition, there is an appliance in which a unit for causing a battery to emit an LED element that does not require wiring is mounted inside a color cone. As for the AC100V power supply wiring method, there is also a method of simplifying the cable wiring by providing a number of T-shaped branches from one line called a centipede cable.

Problems to be solved by the invention

The installation method of nighttime safety lights as described above is based on the fact that when installing a large number of safety lights, the cables and light bulbs are separated, so the light bulbs can be attached at the time of installation and removed at the time of withdrawal. Since the work requires considerable man-hours and the night work hours are limited, the time required for temporary work and removal work is invaded into the time for the main work, which affects the overall work schedule.

In addition, since an AC 100V bulb is used for the internal illumination lamp, it is necessary to supply power from a power pole or use a private generator. Since power supply from the utility pole takes time to negotiate with the power company and is impractical, almost all private power generators are used. However, due to the construction at night, noise becomes a problem and there are many problems with residents. In addition, the exhaust gas from the engine of the private generator is also a problem. In addition, since a large number of light bulbs are used as security lights, there are also problems in terms of energy saving.

From the standpoint of storage and transportation of security light equipment, self-illuminated color cones using light bulbs cannot be stacked and stored because the light bulb mounting part is inside the color cone, and the storage area increases. Battery-powered color cones cannot be stacked and stored or transported because the batteries are inside.

Means for solving the problem

In order to solve the above problems, the cable with a light emitting unit of the present invention has the following solutions. A cable with a light-emitting unit is used for interior lighting of a security light, and a single composite cable in which a coated feeder line is bonded or embedded in parallel to a belt-shaped rubber cable and a plurality of light-emitting units composed of light-emitting elements are mounted on the cable. It is a cable with a light emitting unit, and is structured to be wound up by a drum. The installation of the security light is completed simply by laying the cable wound around the drum on the road and placing the color cone on the light emitting unit. At the time of withdrawal, the color cone is removed and the cable is wound around a drum.

The light-emitting element of the light-emitting unit is an LED, and power consumption per light-emitting unit is very small. Practical illuminance can be obtained with power consumption about 1/100 that of a light bulb currently used for a security light. Therefore, since it can be driven by a battery for a long time, a private generator is not necessary, and the problems of noise, exhaust gas, and energy saving are solved.

From the standpoint of storage and transportation, it is possible to use commercially available ordinary color cones, which can be stacked and stored, and the storage area is reduced, which is advantageous in terms of transportation. In addition, inexpensive commercially available color cones can be used.

The present invention is a cable with a light-emitting unit in which a light-emitting unit composed of a single cable and one or a plurality of light-emitting elements is attached to a plurality of predetermined positions on the cable. A plurality of power supply blades are provided, and power can be supplied to the light emitting unit simply by inserting the power supply blade directly into the power supply line directly below the light emitting unit.

Further, according to the present invention, a plurality of safety devices can be illuminated at a time only by placing an internally-lighted security device such as a color cone on the light emitting unit on the cable with the light emitting unit.

Further, in the present invention, the LEDs in the light emitting unit are connected in series, and the total of the voltage drop of the LED and the voltage drop of the current limiting resistor is configured to be equal to the power supply voltage from the power supply line.

In addition, the present invention is configured such that the LEDs in the light emitting unit are arranged in a straight line and a power supply line is arranged directly below, and even if a force is applied to the LED from above, the power supply line receives the force from the LED and supplies power. Strengthened the pressure resistance from above the unit.

In addition, according to the present invention, the supply voltage in the light emitting unit can be 12 VDC or other DC voltage, and the power can be supplied by a battery or an AC adapter.

Further, in the present invention, the cable with the light emitting unit has a structure in which a groove is dug in a belt-like rubber and a power supply line is embedded.

The light-emitting cable for security light illumination according to the present invention is a strip-shaped cable having a ratio of the width and height of the lower section of 4: 1 or more so that the cable is not easily twisted even when laid on the ground.

In the present invention, even if a plurality of light emitting units are installed on a cable with a light emitting unit, the height of the light emitting unit is lower than the drum diameter, and the entire cable can be wound around the drum.

Further, according to the present invention, the cross section of the cable with the light emitting unit is trapezoidal, which improves the winding performance of the cable and reduces the weight of the entire cable.

Further, according to the present invention, the light-emitting unit attached to the cable with the light-emitting unit can be attached and detached, and by installing the light-emitting unit at a predetermined security light installation interval, the security light can be installed without measuring the installation interval at the site.

Also. As described above, the cable with a light emitting unit of the present invention can be used as it is with a commercially available color cone as it is without changing the color cone. be able to. Hundreds of color cones must be installed depending on the construction site, and the use of this cable with a light emitting unit can greatly save labor.

A case where a large number of color cones are installed as security lights in the civil engineering work of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention. It is composed of a color cone illumination cable 2 and a light emitting unit 1 composed of LED elements attached thereto, a battery 4 or a DC power supply 4 and a drum 5 around which the cable is wound. The color cone 3 is placed directly above the light emitting unit, and is a commercial product that has not been processed.

The color cone 3 illuminating cable 2 is constituted by a belt-like rubber or a similar material and a power supply line, and the length is an arbitrary single cable. The light emitting unit 1 is attached in a state of being integrated with the cable 2 at a specific distance of the cable, for example, at an interval of 2 m, and in the case of a 30 m cable, 15 light emitting units are attached.

2 is a detailed view of the light-emitting unit 1 attached to the cable, FIG. 2A is a side view, and FIG. 2B is a cross-sectional view. In FIG. 2A, five LED elements 6 are attached to the substrate 8 in series. Two plus and minus two power supply blades protrude from the substrate 8 downward and are inserted into the power supply line of the cable 2. The voltage of the power supply line is DC12V. The light emitting unit 1 is in contact with the power supply line by the power supply blade, is detachable, and can be installed at any place on the cable. The light emitting unit 1 is attached to the cable 2 by inserting the cable 2 between the main body of the light emitting unit 1 and the back plate 12 and penetrating the light emitting unit 1 with screws.

The light emitting unit 1 is, for example, 52 mm long, 20 mm wide, and 7.3 mm high in a rectangular shape, the short side is within the width of the cable 2, the long side is in the cable direction, and the cable 2 is connected to the drum 5. Easy to wind.

Regarding the brightness of the safety light, the LED element 6 is a high-intensity red LED, and has a luminance of 10000 millicandelas or more, the wavelength of the red LED coincides with the transmission wavelength of the red color cone, and the energy loss is In addition, the color cone 3 becomes more constrained toward the upper part, and the entire color cone 3 is formed by a combination of irregular reflection and direct light when the LED emits light directly upward in relation to the irradiation angle of the LED. Becomes brighter. Due to these synergistic effects, the brightness equivalent to a 40W incandescent lamp can be secured even with a 0.4W ED.

FIG. 3 is a cross-sectional view of the cable 2. The cable 2 is composed of a cable base 10 and a feeder line 9 and has a trapezoidal shape with a width of 30 mm. The material is rubber. A groove is dug in the center of the upper portion of the cable base 10 to house the feeder 9. The feed line 9 is half out. This is because it also serves as a guide for the light emitting unit 1. The reason why the cable base 10 is trapezoidal is that it aims to reduce weight and ease winding. Since the cable base 10 has a width of 30 mm and does not twist even when extended, the light emitting unit 1 can always face upward. Moreover, since it is belt-shaped, it can be wound on a drum.

The detailed structure of the light emitting unit 1 will be described with reference to FIGS. FIG. 2 is a structural diagram of the light emitting unit of the present invention. Five LED elements 6 are arranged on the substrate 8, and each LED is directly connected from the cathode to the anode of the adjacent LED. The anode and cathode of the terminal LED are each pressed into contact with the positive core wire of the two-core cable from the anode power supply blade 9. The cathode is pushed and connected to the negative core wire via the power supply blade 9. Both break the cable sheath and connect to the core. Therefore, there is no need for any processing on the two-core cable. In addition, the installation interval can be changed. When the LED voltage is 2.5V, the 5 LEDs are connected in series at 2.5x5 to 12.5V. If 12V is supplied to the power supply, the LED's current can be limited by the current limiting resistor for LED lighting within the specified voltage. Can be lit. The cable is taken inside the light-emitting unit 1, and the inside is hardened with resin, etc., to strengthen the external strength, waterproof and insulate.-

Since the present invention is configured as described above, the following effects can be obtained. Since the light emitting unit is semi-fixedly mounted on a single cable at predetermined intervals and placed on the cable ground or floor surface, the installation work only needs to extend the cable, and the color cone can be installed quickly and Can be done efficiently. In addition, since the light emitting unit is small and arranged in the cable direction, the cable can be easily wound and wound with a drum or the like.

In this way, the cable with light emitting unit of the present invention can be used as a normal daytime color cone as it is without changing the color cone, and the daytime color cone can be made into a self-illuminating safety light for night construction simply by laying the cable. Can do. Hundreds of color cones must be installed depending on the construction site, and the use of this cable with a light emitting unit can greatly save labor.

Since commercially available color cones are used, a large amount of color cones can be stacked and stored and transported from the transportation and storage side, thereby saving space.
