LED flashlight utilizing physical means to transform range

Abstract

The invention discloses an LED flashlight utilizing physical means to transform the range. The LED flashlight comprises a shell. The LED flashlight has the innovation point that a physical structure is utilized to light up LED lamp beads with different focuses, and thus the purpose of changing upper and lower beam irradiation of the flashlight is achieved; the flashlight is provided with an adjusting disc, the three LED lamp beads with the different focuses are arranged on the adjusting disc, the center of the adjusting disc is connected with one of wiring pins of each LED lamp bead through arotating shaft, the other ends of the wiring pins communicate with a lithium battery through wires, the other wiring pins of the LED lamp beads communicate with contact blocks arranged inside groovesin the edge of the adjusting disc, and the different grooves are controlled to make contact with contact strips by rotating the adjusting disc; due to the fact that the contact strips are connected with the other pole of the lithium battery, when the contact blocks and the contact strips make contact, the LED lamp beads corresponding to the contact blocks are lighted up, and the adjusting disc communicates with one of electric poles of the lithium battery through cooperation of the rotating shaft and a bearing; and the LED flashlight is more reasonable and compact and is used by an operator more advantageously.

Description

technical field [0001] The invention relates to the technical field of variable-focus LED flashlight equipment, in particular to an LED flashlight that uses physical means to change the shooting range. Background technique [0002] At present, the flashlights commonly used by people have more than one bulb and one style. In many cases, the effect is poor and it is easy to cause unnecessary waste of electricity. In order to meet the needs of different environments and the needs of energy saving, there is an urgent need for an existing high beam , and low-beam flashlights, but traditional dimming flashlights are realized by adjusting the luminous intensity of the bulb. Frequent adjustments will damage the bulb and cause trouble to use. Therefore, we propose a LED flashlight that uses physical means to change the range. to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide an LED flashlight that uses physical means...
