Abstract
The utility model relates to an LED (light emitting diode) electric torch, in particular to a magnetic induction stepless speed change dimming LED electric torch, which consists of an electric torch body, a circuit board, a circuit warehouse, a dimming ring and an LED lamp cap, wherein the electric torch body is screwed with the circuit warehouse, the circuit board is arranged in the circuit warehouse by a locating screw, a magnetic induction follower (MLX90316) is arranged on the circuit board, the dimming ring is arranged at the periphery of the circuit warehouse and can rotate around the circuit warehouse and can not drop off, two splicing grooves are axially and symmetrically arranged on the circumferential edge of the dimming ring, magnets are arranged in the splicing grooves, and the LED lamp cap is concentrically fixed above the dimming ring. In the utility model, the brightness can be adjusted as required by slowly adjusting the dimming ring, the operation is convenient, simple and easy, adjustment is convenient and the usage is quite convenient; moreover, the dimming mode is linear adjustment, so that eyes can not have an unconformable feeling by light intensity changed suddenly when the LED electric torch is used.
Description
Technical field
The utility model is a kind of LED flashlight, particularly a kind of magnetic induction infinitely variable speeds dimming LED (Light Emitting Diode) flashlight.
Background technology
The LED flashlight all has a kind of function that the power of light is adjusted to how appropriate according to the needs that use, but existing LED flashlight can only be jumped the position and regulate, in other words the adjusting of light power, light, exists tangible luminosity and changes the sense of jumping to highlighted from low high light.The jump sense of this light intensity is felt very ill the people, and it is tired that eyes are produced.
Summary of the invention
The purpose of this utility model is can only jump the defective that the position is regulated to the light power in order to overcome existing LED flashlight, invents the magnetic induction infinitely variable speeds dimming LED (Light Emitting Diode) flashlight that a kind of light intensity can realize linear soft variation.
The purpose of this utility model realizes as follows: described magnetic induction infinitely variable speeds dimming LED (Light Emitting Diode) flashlight, by stack shell, circuit board, the circuit storehouse, light modulation ring and LED lamp holder are formed, stack shell and circuit storehouse are bolted in one, circuit board is arranged in the circuit storehouse by dog screw, circuit board is provided with magnetic induction follower (MLX90316), the periphery in circuit storehouse is provided with the light modulation ring, the light modulation ring can rotate around the circuit storehouse, but can not come off, on the circumferential edge of light modulation ring vertically symmetry have two inserting grooves, be provided with magnet in the inserting groove, the LED lamp holder is fixed on light modulation ring top with one heart; Magnet will rotate synchronously when rotating the light modulation ring, cause the magnetic field around the magnetic induction follower to change, and the magnetic induction follower is sensed the purpose that the signal that will export different brightness after the variation in magnetic field reaches light modulation.
Good effect of the present utility model is as follows: the utility model is to regulate the brightness of oneself wanting by rotary light adjustment ring slowly, and it is easy to operate, and is simple, makes in adjustment, very convenient to use; Because dimming mode is linear the adjustment, its intensity of illumination can so in use eyes can not be subjected to the light intensity of flip-flop and produce incompatible sense, can well be protected eyes from 1 lumen to there not being the change of jumping 150 lumens continuously.
