现有技术中的手电筒的亮度不会发生变化，然而，由于用户需要使用手电筒照亮不同远近距离的区域，因而，当用户照射较近距离的区域时，如果亮度过大，则会发生花眼的现象；而当用户照射较远距离的区域时，如果依然使用相同亮度，那么则会由于距离较远、光线较弱而不能清楚地观察。The brightness of the flashlight in the prior art does not change, however, because the user needs to use the flashlight to illuminate areas of different distances, therefore, when the user illuminates a relatively short-distance area, if the brightness is too large, blindness will occur. Phenomenon; and when the user illuminates a longer distance area, if the same brightness is still used, then it will not be able to be clearly observed due to the longer distance and weaker light.
