Specific embodiment

As depicted in figs. 1 and 2, the LED hands shown in structural representation and Fig. 1 that it is respectively LED flashlight of the present invention 10 The exploded perspective view of torch 10.

The LED flashlight 10, including be packaged with the shell 130 of substrate 110 and substrate 110 connection of LED lamp bead 111, set The controller 120 that electrically connect in the shell 130 and with LED lamp bead 111, in shell 130 and it is LED lamp bead 111 and controls The power supply of the power supply of device 120 and the lampshade 140 being connected with shell 130.Shell 130 is connected one end with substrate 110 and is provided with multiple dissipating Hot hole 131, is additionally provided with switch 132 on shell 130, the outer wall of shell 130 is provided with corresponding with louvre 131 movable The first catch 160, the first catch 160 132 is connected with switch.First catch 160 and switch 132 are all relative to shell 130 Mobilizable, first catch 160 is also and then moved so when switch 132 has mobile.

It is circle that shell 130 is connected one end with substrate 110, and the other end of shell 130 is square.Wherein, the end of circular one end Face area is bigger than the face area of square one end.A handle is provided between circular one end and square one end of shell 130 133, the switch 132 on shell 130 can also be and be located on handle 133.

The inwall of shell 130 is provided with mobilizable second catch 161 corresponding with louvre 131.Shell 130 is dissipating The marginal adhesion of hot hole 131 has the humidity sensor 134 electrically connected with controller 120, and shell 130 is interior to be provided with and the electricity of controller 120 The motor 170 of connection.Motor 170 is connected and with the second catch 161 for driving the second catch 161 to move.Motor 170 can pass through Screw rod is connected with the second catch 161.Humidity sensor 134 can be used to measure the relative humidity of air, when the humidity of air reaches During to preset value, controller 120 will send control signal controlled motor 170 and rotate, so as to drive the second catch 161 to move will dissipate Hot hole 131 is closed.During the second catch 161 closes louvre 131, when humidity sensor 134 detects the humidity of air During less than preset value, controller 120 can again send control signal controlled motor 170 and rotate, and driving the second catch 161 to move will Louvre 131 is opened.

Radiator 150 is additionally provided with shell 130, radiator 150 is connected to help substrate 110 to radiate with substrate 110.Dissipate Hot device 150 includes that one is used for the connecting plate 151 being connected with substrate 110 and the multi-disc fin being connected with connecting plate 151 152, connecting plate 151 scribbles heat conductive silica gel with the joint face of substrate 110.
