Portable lighting alarm device

Abstract

The invention discloses a portable lighting alarm device comprising a shell, a lighting unit, a sensing unit, a switching unit, a warning unit, an electronic control unit, and a battery unit, whereinthe lighting unit is mounted on the shell, the sensing unit is used for sensing external vibration and outputting a sensing signal, the switching unit is used for switching different use modes to output a first lighting signal or an alert signal, the warning unit is used for generating sound, and the battery unit is used for supplying required electric energy. When the electric control unit receives the first illumination signal, the lighting unit can be controlled to produce bright light; when the electronic control unit receives the alert signal and the delay time is counted, the electroniccontrol unit enters an alert mode, and when the electronic control unit enters the alert mode and receives the sensing signal, the alert unit is controlled to generate sound and the lighting unit is controlled to generate light. Therefore, besides the lighting function, the earthquake sensing and warning functions are also achieved, a user can be prompted to place and position the portable lighting alarm device from a moving state to a positioning state through the design of the delay time, and mistaken touch actions are effectively avoided.

Description

technical field [0001] The invention relates to a lighting device, in particular to a portable lighting alarm device. Background technique [0002] refer to figure 1 , an existing earthquake vibration sensing device 1 as disclosed in the Taiwan Patent No. M414589 patent case, mainly includes a sensing unit 11 for sensing vibrations, an alarm unit 12 for generating sound or light , and a processing unit 13 electrically connected to the sensing unit 11 and the alarm unit 12 . The sensing unit 11 includes a linear accelerometer 111 and a rotating gyroscope 112 . In this way, when an earthquake occurs, the processing unit 13 will receive the signals from the linear accelerometer 111 and the rotating gyroscope 112, and after the built-in Extended Kalman Filter (EKF) calculation software is programmed and calculated, Judge the intensity of the earthquake, and generate sound or light to remind residents to be alert. [0003] However, the aforementioned earthquake vibration sens...

Problems solved by technology

[0003] However, the aforementioned earthquake vibration sensing device 1 can only be set in a fixed position, and the timing of judging whether to send a sound or a light depends on the data collected by the linear accelerometer 111 and the rotating gyroscope 112, and requires a complex process. In order to make a correct judgment, there is still room for improvement in terms of response speed and accuracy, and the cost is relatively high
