Abstract

The invention discloses an LED electric torch. The LED electric torch comprises a base plate, a shell, a controller, a power supply and a lampshade, wherein an LED bulb is packaged on the base plate; the shell is connected with the base plate; the controller is arranged inside the shell and is electrically connected with the LED bulb; the power supply is arranged inside the shell and used for supplying power to the LED bulb and the controller; the lampshade is connected with the shell; one end, connected with the base plate, of the shell, is provided with a plurality of cooling holes; a switch is also arranged on the shell; movable first baffles corresponding to the cooling holes are closely arranged on the outer wall of the shell; the first baffles are connected with the switch. According to the LED electric torch, when a hand turns on the switch by movement, the switch can be used for driving the first baffles to generate displacement so as to open the cooling holes, so that the cooling holes can have a cooling effect to improve the cooling efficiency; when the switch is turned off, the baffles can be driven to return to close the cooling holes, so that dust is prevented from entering the shell.

Description

technical field [0001] The invention relates to a flashlight, in particular to an LED flashlight. Background technique [0002] LED (Light Emitting Diode), that is, semiconductor electric light source, light-emitting diode, also known as semiconductor lamp, is a kind of electric light source without filament, which directly converts electrical energy into light energy. [0003] LED flashlight has the characteristics of energy saving and long life, and is favored by more and more users. However, the heat dissipation problem of the LED flashlight is also a key issue, and the heat dissipation problem seriously affects the light efficiency and life of the LED light source. Traditional LED flashlights have low heat dissipation efficiency, which leads to excessively high temperature of the LED light source, which affects the light efficiency and lifespan of the LED. Contents of the invention [0004] Based on this, it is necessary to provide an LED flashlight with higher heat ...
