LED BIKE SAFETY VEST (HIKARI VEST)

Abstract

This study intended to develop a motorcycle safe vest that can be prepared against accidents by mounting a smart module (with Gyroscope accelerometer) on the safe vest in order to emphasize safety among functional aspects of the bike clothing. The research method investigated professional books, prior research, and Internet data to examine the characteristics of bicycle wear and the theoretical examination of smart wear, and analyzed the functional characteristics of the design by reviewing smart jacket and vest design cases for bikes currently on the market. Overall, LED Vest is a light strip controlled by a microcontroller safely applied to a wearable fabric, such as a vest. From this point, we can build on this idea, making it weatherproof, lightweight, portable, and even communicate with other devices.The LED vest works by using an Arduino to control a set of LED strips (WS2812B) based on the User’s action. The Arduino can also control individually addressable RGB LED from the LED strip of the rider to either left or right side to obtain data on left or right direction, sudden stop, and so forth and displayed left or right turn signal and sudden stop sign on the backplate (back) through the LED module. As for charging the device to operate LEDs When it comes to the LED Vest, keeping safety in mind is important. As a result, a battery would be required which is small enough to fit in the Bike Vest and durable enough to withstand hard drops and external hits.The Li-Po was an initial choice. It’s small and compact. But where it falls is that it doesn’t have much protection and can be an issue if it gets damaged or punctured.As an alternative, a Lion RC battery pack was used as the next best alternative. It’s sturdy, durable, and can withstand harsher conditions. The only factor we have to compromise is the size. As a result, the LED remote and Suit electronics footprint would be slightly larger.With a limited scope to LED-applied safety vest, this study contemplates on the problems of safety vest on the market and directions for design development with a view to develop its prototype. This is a significant study because it has been conducted concerning a prototype, a cut above the study method of constructing a basic theory. For study method, theoretic considerations on LED and safety vest are followed by case study for LED-applied safety vest currently on the market to draw out problems. Then, solutions for problems with LED safety vest will be found, while planning for a design direction in consideration of safety, functionality and beauty. Scope of study was limited to cases of LED safety vests currently on sale online and offline, excluding cases of common-form luminosity such as HB luminous vest without LED. Accordingly, results of study will help develop the prototype for LED safety vest with an increase of the wearer's safety, and be used as a basic data for developing high-value-added fashion prodcts to meet his aesthetic sense and functionality. This study has limitations. Restricted scope for LED-applied safety vest should be extended to an outdoor wear in follow-up research for the foundation of higher value added.
