Abstract

The present invention relates to one kind of electric torch with simple structure, and adjustable brightness and stroboflash time. The electric torch includes one battery, one barrel, one electric light emitting body and one tail cover, and features two contacting tabs connected separately to two poles of the battery, one circuit board with microcomputer controller to control power source to the electric light emitting body, and two springs on the circuit board and connected to the microcomputer controller and two contacting tabs. The battery powers the microcomputer controller through two springs, and the microcomputer controller controls the brightness and stroboflash time according to the depression number or time on the switch in the tail cover.

Description

technical field [0001] The invention relates to a flashlight. Background technique [0002] The existing flashlight includes a battery, a barrel, an electroluminescent body, a tail cap and a switch, wherein the switch is fixed in the middle of the barrel, and the positive pole of the battery, the electroluminescent body—that is, the electric ball, the switch, and the spring inside the tail cap form an electrical circuit , After the switch is turned on, the electric beads can emit light. The disadvantage of this kind of flashlight is that it has a single function and cannot adjust the brightness of the light. Contents of the invention [0003] The object of the present invention is to provide a flashlight with simple structure, adjustable brightness and strobe time in order to solve the problem of single function and inability to adjust the brightness existing in the existing flashlight. [0004] Technical solutions: [0005] The object of the present invention is achieve...
