Helmets, as a protective product for the head, have become necessary equipment in many outdoor activities. At the same time, as the pace of life accelerates, most people have to go to the office during the day and can only do outdoor sports after work. However, darkness comes on after work, and the road condition cannot be determined in default of illumination. Moreover, when people or cars pass by, it is impossible to remind the other party, which leads to a safety accident. Therefore, the helmet is required to be able to illuminate and remind at night.

[03] In the prior art, most helmets only have a glowing reminder function or only have an illumination function, which is relatively single. Moreover, most helmets use LED arrays for arrangement and combination to emit light, which is easy to cause glare, and the emitted light is dazzling, which is very harmful to human eyes; the LED arrays generate a large amount of heat, which is accumulated in the helmet shell and not easily to dissipate, and thus LEDs stay in a high temperature environment for a long time, which shortens the life of the LEDs and also makes the user uncomfortable; and the helmet with the illumination function mostly use independent illumination fixtures, which are fixed to the helmets with straps or other fixing devices, and thus the illumination direction cannot be adjusted.
