Directional lighting wrist lamp and control method thereof

Abstract

The invention discloses a directional lighting wrist lamp and a control method of the directional lighting wrist lamp. The directional lighting wrist lamp comprises a first base, a second base and a double-shaft cradle head, wherein the second base is connected with the first base through a bendable support shaft, and the double-shaft cradle head mechanism is arranged on the second base and is provided with an LED (light emitting diode) lamp, wherein a control chip which is electrically connected with the double shaft cradle head mechanism and a power supply for supplying power to the double shaft cradle head mechanism are arranged inside the first base; an acceleration meter gyroscope module for acquiring the motion state of the wrist is further arranged on the second base; the acceleration meter gyroscope module is electrically connected with the control chip; and a wrist belt which is used for being connected with the wrist is further arranged on the first base. The directional lighting wrist lamp is simple in structure and convenient to manufacture and use, can ensure that the direction that the light emitted from the wrist lamp is constant during the motion of the wrist, and can also realize directional lighting by which the radiation direction of the light can be controlled by only through the motion of the wrist.

Description

technical field [0001] The invention relates to a wrist light capable of capturing and responding to wrist movements. In particular, it relates to a directional lighting wrist lamp and a control method thereof, which utilize a MEMS accelerometer and a MEMS gyroscope for motion capture, and control light through a microprocessor and a servo motor. Background technique [0002] The flashlight has been widely used by people for a long time, and it provides people with a lighting tool that can be carried and used flexibly. But flashlight use requires one hand to hold, which makes it difficult to use flashlight lighting for many activities that require two-handed operation. Many activities such as camping and repairing fuses are inconvenient to use other light sources, which brings great inconvenience to life. In view of this, people try to use wrist lights to free their hands. But a huge problem with wrist lights is that tiny movements of the wrist can also cause huge deflect...
