Description

Safety Clothing with Flexible LED Board {SAFETY CLOTHES HAVING FLEXIBLE LED BOARD}

The present invention relates to a safety garment equipped with a flexible LED substrate, and more particularly, by mounting a flexible substrate with an LED formed on the garment to significantly improve the visibility from others, to prevent various accidents, and by human activities or washing The present invention relates to a safety garment equipped with a flexible LED substrate having improved durability and a feeling of wearing, which can prevent damage or failure of an LED device.

In general, people who enjoy sports, such as cycling, inline skating, and running, wear specialized clothing for the sports. Such clothing for sports wear provides various conveniences to the wearer to enjoy the sports, but at night, rainy weather, heavy fog. In forested mountains, there is a problem that can not be recognized by others. In particular, the lack of visibility in the case of a bicycle, inline skating, running, etc., which are not easily seen by pedestrians or drivers at night, and are moving at a high speed, may lead to an accident with a pedestrian or a vehicle.

Therefore, it is desirable that the clothing for sports wear can be recognized by pedestrians and drivers even under conditions such as nighttime when the clock is poor, so as to prevent damage to human life or equipment due to a collision.

In addition, as the recent activity of mountain climbing or walking is active, the number of people enjoying it is increasing. However, in the forest-dense mountains, sunlight is sometimes shaded by the shade of trees, and there are also environmental features that rapidly darken at sunset. Unlike the urban environment, these environmental features and mountains, unlike ordinary cities, can be distressed because they can't follow the predecessor or can't identify the road. As such, there is an increasing demand for functional safety clothing that can be easily identified by others at a distance even when hiking.

In addition, at night police officers often check cars on the road to detect drunk driving, escape or search vehicles. However, in the case of clothing or equipment in which the existing fluorescent material is formed, it is not enough to attract the attention of the driver, it is not easy to recognize the police officers, and the police are often injured accidents.

Therefore, in order to protect valuable lives from various safety accidents, there is a demand for improvement measures to prevent the police officers from being easily identified from the surroundings and suffering from automobiles.

Accordingly, in recent years, technologies for installing light sources on clothes so that a user who wears the clothes can be easily recognized by others are being developed.

However, these technologies do not guarantee activity by mounting LEDs on printed circuit boards that are not bent or bent. Furthermore, by using general wires, wires may be shorted due to human activity, or may penetrate water when raining or washing. Due to frequent equipment failures, reliable safety clothing cannot be provided.

In addition, as an example of such a conventional technology, Korean Utility Model Registration No. 20-0240675 (October 12, 2001) stores a light emitting body that emits light, so that clothing can be easily identified even at night. It can be mentioned, but this also has a problem that is not enough visibility.

That is, such a garment can be easily broken when washing or strong impact from the outside, and since the LED used as the light source applies light to the end of the polymer, which is a light transmission medium, rather than directly emitting to the front, There is a problem that the recognition of the wearer of the clothing is improved, but the recognition of the wearer is far from the distance.

Therefore, an object of the present invention is to improve the identification and ambient ventilation power for the wearer even in a bad watch situation, it is possible to prevent accidents such as traffic accidents in advance, easy to wash, improved durability and wearing comfort flexible LED substrate To provide safety clothing fitted.

In order to achieve the above object of the present invention, in one embodiment of the present invention, in the clothing attached to one or more LED chips for emitting light, the flexible LED substrate is mounted on the clothing, the one or more LED chips are mounted, It provides a safety clothing equipped with a flexible LED substrate including a power supply means for supplying power to the flexible LED substrate and a cable connecting the power supply means and the flexible LED substrate.

When the present invention is used as sports clothing such as cycling clothing and inline skating clothing, even when enjoying sports in a dark natural environment, it is possible to recognize the movement of the wearer to the driver or pedestrian by emitting light through the LED chip applied to the clothing. Accordingly, the person wearing the safety clothing according to the present invention can prevent accidents colliding with drivers or pedestrians even if they enjoy sports in the late evening or dawn.

And when the clothing according to the present invention is worn at night mountaineering, it is possible to easily recognize the position of the wearer to the person climbing together, it is possible to smoothly transmit the position of the wearer to the rescuer in case of emergency.

In addition, the present invention can minimize the damage caused by impact or washing provided from the outside using a flexible LED substrate. In addition, the present invention by using a conductive yarn provided in the state sewn on the clothing instead of a general-purpose cable such as a wire as a cable connecting the power supply means and the LED substrate, the weight of the clothing is reduced, and the wearing feeling of the clothing is improved.

In addition, the flexible PCB 14 includes a base electrode, and copper, gold, silver, or the like may be used as the base electrode. The flexible PCB 14 is configured to control the LED chip 12 uniformly by applying the same power to the LED chip 12 connected to the base electrode, or independently of the LED chip 12 connected to the base electrode. By applying power, a configuration capable of individually controlling each LED chip 12 may be used. In addition, the base electrode is provided on the flexible PCB 14 in various forms so that the plurality of LED chips 12 can be installed in various forms according to the purpose of use of the garment 2.

For example, the base electrode may be configured such that the plurality of LED chips 12 may represent symbols, letters, or aesthetics such as arrows, and the like, and may adjust the color or the flashing speed thereof. have. Specifically, for sports clothing that moves at a relatively slow speed, such as hiking or walking, the LED may be kept on or the blinking speed may be slow, and the blinking speed of the LED may be high if the movement speed is high, such as cycling or inline skating. By increasing the visibility and alerting effect to speed up, it is possible to prevent the risk of accidents caused by fast movement of the wearer.

The plurality of LED chips 12 may be provided in a predetermined arrangement on the flexible PCB 14, and may be fixed by a thermal fusion method by solder, and electrically connected to the base electrode. At this time, the LED chip 12 is an LED unit having one or more R, G, B LEDs that emit red (R: R), green (G), and blue (B) light, respectively, for color display. It can be formed as a unit. The LED unit units are adjacent to each other and mounted on the substrate at predetermined intervals. Color-specific LEDs of each LED unit unit may be provided to be driven independently of each other or at the same time according to the control of the flexible PCB 14 for controlling the power supplied. In other words, the LED chip 12 adjusts the output intensity of each R / G / B light under the control of the flexible PCB 14 to synthesize the light necessary for the wearer's situation.

The LED chip 12 is preferably mounted on the garment 2 so as to be exposed to the outer side of the garment 2.

In this case, the one or more LED chips 12 may be mounted to be detachably attached to only the required portion of the front surface of the outer clothing and the rear surface of the outer clothing as shown in FIG. 4 as shown in FIG. 3.

In addition, the garment 2 according to an embodiment of the present invention includes a power supply means 20.

The power supply means 20 is attached to the garment 2 to supply power to the flexible LED substrate 10, and includes a storage battery in which electrical energy is stored.

Here, although any one of a disposable battery, a rechargeable battery, or a charging capacitor may be used as the storage battery, it is preferable to use a charging capacitor.

In this case, when the disposable battery is used as the storage battery, a battery replacement cost is generated when the battery is replaced, but the design of the garment 2 may be simplified.

On the contrary, when the rechargeable battery is used as the storage battery, there is an advantage in that the replacement cost of the battery is not generated. However, the size of the battery is larger than that of the disposable battery, which reduces the fit of the clothing 2.

Finally, the use of the charging capacitor as the storage battery, there is an advantage that not only does not incur a battery replacement cost, but also its size is smaller than the rechargeable battery can minimize the problem of a drop in fit due to the volume and weight of the battery. .

As an embodiment, the power supply means 20 according to the present invention is formed of a power supply means PCB 22 and a storage battery 24 electrically connected to the power supply means PCB 22 as shown in FIG. Can be. At this time, the power supply means PCB 22 is provided with an output terminal 28 for supplying power stored in the battery 24 to the outside.

In order to prevent this, it is preferable to use a conductive yarn that is an electrically conductive yarn as the conductive means 32 of the cable 30 connecting the power supply means 20 and the flexible LED substrate 10. Such conductive yarns may be provided inside the outer shell of the garment 2 in a state of being sewn to the garment 2, and thus do not require a separate attachment space.

Here, the conductive yarn is a composite fiber having conductivity close to a metal, and can be obtained by forming a conductive layer such as copper or carbon black in the center of the fiber using polyester, nylon, acrylic fiber, or the like as a matrix.

In addition, the conductive yarn may be coupled to the garment 2 through a sewing process, but has a conductivity to provide the flexible LED substrate 10 with power supplied from the power supply means 20, Since the body is not exposed to the outside and does not come into contact with the wearer's body, the feeling of wearing does not decrease. In addition, since the conductive yarn is lighter than a normal cable, the use of the conductive yarn can substantially reduce the weight of the garment 2.
