In Taiwan, Li Yaqin, who has not studied mechanics, physics and electrical engineering, has spent the next two years studying and designing the world's first LED bulb. The wind is blowing at night.
According to the admixture, about three years ago, Li Yaqin began to study the production of a light nighttime wind. He relied on his own exploration and consulting with the experts of the Industrial Engineering Institute to design a nighttime wind composed of LED bulbs that were two-thirds smaller than the original bulb. Li Yaqin pointed out that he changed the wind Hagbu from the original nylon to the sail fabric for the light and not easy to rupture paraglider. The wind and the Hart line were also changed to the yarn material used in the bulletproof vest. The skeleton was also changed from bamboo raft to carbon fiber. U, the wind has become lighter and more durable, and the LED bulb can be reused. Therefore, if it is well preserved, it is not a problem to have a wind for two or three decades. "The cost of a light bulb is eighty yuan. A wind needs about one hundred light bulbs, plus the wire and wind Hagbu. The cost of a wind is about 26,000." Li Yaqin It is said that the cost of LED bulbs is now reduced, and about 20,000 Taiwan dollars can make a good night wind.
Li Yaqin said that he had to go to work during the day, and he couldn’t let the wind go at night, so that the office workers were really troubled. At home and abroad, the fluorescent rods were used to make the wind bright at night, but the fluorescent sticks and bulbs were too heavy. Not high.
