Further specifically, the preset rule mentioned in this embodiment is: when the automatic flashing light is used for the first time, the automatic flashing light mode is directly entered after the automatic flashing light mode is started, the automatic flashing light mode is represented by five light display modes which are automatically and sequentially displayed in a circulating mode until the system detects that the Hall switch is continuously switched on for 3 times within 2 seconds, and the light display modes are switched according to the mode switching sequence from the mode (1) to the mode (5) and then to the mode (1); when the LED lamp is not used for the first time, the LED lamp directly enters a light display mode in which the LED lamp is located when the LED lamp is turned off for the last time after the LED lamp is turned on until the Hall switch is continuously turned on for 3 times within 2 seconds, and the light display mode is switched according to a mode switching sequence from the mode (1) to the mode (5) and then to the mode (1).
More specifically, when the portable lighting device is used for the first time, if the user wants to set the lighting display mode to the mode (3), the user can first switch the mode to the mode (1), then to the mode (2), and then to the mode (3) by using a mode switching manner (i.e., quickly disconnecting and attracting the first magnet 201 and the second magnet 202 within 2 seconds); when the lamp is not used for the first time, the lamp directly enters the lamp display mode (for example, the mode (3)) in which the lamp is turned off last time after the lamp is turned on, and if a user wants to set the lamp display mode to the mode (1), the user can firstly switch the mode to the mode (4), then switch the mode to the mode (5) and then switch the mode to the mode (1) by adopting a mode switching mode. And so on.
Further preferably, the method further includes step S5, querying power supply capacity, and entering a low-power reminding mode when the power supply capacity is lower than a preset capacity threshold. The safety warning lamp of this embodiment, when the electric quantity is not enough, get into low electric quantity and remind the mode, and the mode is reminded to low electric quantity: first LED lamp (i.e. the lamp that is closest to first end 101 department of body 1) constantly glimmers, and other lamps extinguish, so, the user can in time charge the safety warning lamp according to the demonstration condition of lamp.
Further preferably, the method further includes step S6, receiving a shutdown signal of the hall switch, and automatically shutting down after a second set time according to the shutdown signal. Preferably, the second setting time of the present embodiment is 30 seconds. In this embodiment, after the system receives the shutdown signal of the hall switch (i.e., detects that the first magnet 201 is separated from the second magnet 202), the light is not immediately turned off, but there is a delay of up to 30 seconds. Setting a delay of 30 seconds is intended to enhance the user experience.
Further preferably, the light display mode includes a pattern light mode, a breathing light mode, a slow flashing mode, a flash mode and a flashing mode. In this embodiment, can carry out the setting of light display mode according to user's individual hobby, can promote user experience, the practicality is better.
Although the present invention has been described to a certain extent, it is apparent that appropriate changes in the respective conditions may be made without departing from the spirit and scope of the present invention. It is to be understood that the invention is not limited to the described embodiments, but is to be accorded the scope consistent with the claims, including equivalents of each element described.
