Japanese Patent JP5058616
Kind Code:
B2
Abstract:
The headlamp has a functional block for detecting the focus of solar rays and triggering a protection unit. A folding blade (18) and LED (3) are respectively placed at focal spots (F`, F). The blade is mounted on an adjustable core (19) of an electromagnet (20). The electromagnet is excited when heating of the LED is detected so as to displace incidence point (I) of solar rays on the blade to a point different from the focal spot (F`) such that solar rays follow an optical path (R2`) different from that of an optical path (R2).
