Detailed description of the invention
As depicted in figs. 1 and 2, it is respectively the exploded perspective view of the structural representation of LED flashlight 10 of the present invention and the LED flashlight 10 shown in Fig. 1.
This LED flashlight 10, comprises the substrate 110 being packaged with LED lamp bead 111, the shell 130 be connected with substrate 110, is located in shell 130 and the controller 120 be electrically connected with LED lamp bead 111, is located in shell 130 and is the power supply that LED lamp bead 111 and controller 120 are powered and the lampshade 140 be connected with shell 130.Shell 130 is connected one end and is provided with multiple louvre 131 with substrate 110, shell 130 is also provided with switch 132, and shell 130 outer wall is close to and is provided with mobilizable first catch 160, first catch 160 corresponding with louvre 131 and is connected with switch 132.First catch 160 and switch 132 are all mobilizable relative to shell 130, like this switch 132 have mobile in the first catch 160 also and then mobile.
Shell 130 is connected one end for circular with substrate 110, shell 130 other end is square.Wherein, the face area of circular one end is larger than the face area of square one end.Between circular one end and square one end of shell 130, be provided with a handle 133, the switch 132 on shell 130 can also be located on handle 133.
Shell 130 inwall is close to and is provided with mobilizable second catch 161 corresponding with louvre 131.Shell 130 has the humidity sensor 134 be electrically connected with controller 120 at louvre 131 marginal adhesion, be provided with the motor 170 be electrically connected with controller 120 in shell 130.Motor 170 is connected with the second catch 161 and for driving the second catch 161 to move.Motor 170 is connected with the second catch 161 by screw rod.Humidity sensor 134 can be used for measuring the relative humidity of air, and when the humidity of air reaches preset value, controller 120 will send control signal and control motor 170 and rotate, thus driving the second catch 161 moves and closed by louvre 131.At the second catch 161 by louvre 131 closed period, when humidity sensor 134 detects the humidity of air lower than preset value, controller 120 again can send control signal control motor 170 and rotate, and drives the second catch 161 to move and is opened by louvre 131.
