盲人晚上外出很不方便,过马路时,如果路上灯光不好,很容易出交通事故。为此,我设计了一种会发光的路杖,它的杆身上安装了若干个发光二极管,杆底安装了2个小轮和1个小发电机。行走时,推动路杖的小轮,小轮即带动发电机工作,点亮发光二极管。晚上使用时,这种路杖特别醒目,可以提醒驾驶员及时减速。 Blind people go out very inconvenient at night, crossing the road, if the road lighting is not good, it is easy to a traffic accident. To this end, I designed a shining rod that had several LEDs mounted on the shaft and two small wheels and a small generator mounted on the bottom of the pole. When walking, promote the small ferry rod, ferry that led the generator work, light the light-emitting diode. When used at night, this stick is particularly eye-catching, can alert the driver to slow down in time.
