Structural design

When choosing a headlamp, you should not only pay attention to the light source, circuit design, material and workmanship, but also see whether the structure is reasonable and reliable, whether the lighting angle can be adjusted up and down when wearing it on the head, whether the power switch is easy to operate, and whether it can be turned on unintentionally when it is put into the backpack, When you need to use the headlamp in the evening, when you take it out of the backpack, you will find that the headlamp is turned on. Originally, his switch is designed to be as cutting-edge as an egg. When you put it in the backpack, it is easy to turn it on unintentionally because of the shaking of the backpack during the movement. When you need to use it at night, you will find that the battery has consumed most of the battery.
