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.

Also be provided with radiator 150 in shell 130, radiator 150 is connected with substrate 110 for helping substrate 110 to dispel the heat.Radiator 150 comprises one for the connecting plate 151 be connected with substrate 110 and the multi-disc fin 152 be connected with connecting plate 151, and connecting plate 151 scribbles heat conductive silica gel with the joint face of substrate 110.

Above-mentioned LED flashlight 10, shell 130 is provided with louvre 131 and is conducive to heat discharge in LED flashlight 10.When LED flashlight 10 free time places, louvre 131 can be closed by the first catch 160.When opening switch 132, because switch 132 can move, the first catch 160 is mobilizable and is connected with switch 132, and at this moment switch 132 can drive the first catch 160 to produce displacement to be opened by louvre 131, make louvre 131 play the effect of heat radiation, thus improve radiating efficiency.And when switch 132 cuts out, the first catch 160 can be driven to return movement and louvre 131 is closed, prevents dust from entering in shell 130.

The humidity sensor 134 that louvre 131 edge is provided with can detect the relative humidity of air, when opening LED flashlight 10 when raining or air ratio is moister, the second catch 161 that controller can control to be provided with in motor 170 rotating drive shell 130 moves to be closed louvre 131, can take into account the security of LED flashlight 10.The radiator 150 be provided with in shell 130 can dispel the heat to LED flashlight 10 further.Substrate 110 scribbles heat conductive silica gel with the joint face of connecting plate 151 can reduce thermal resistance, improves radiating efficiency further.

The above embodiment only have expressed the preferred embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
