Description

Gear Lens Dimmable Flashlight

technical field

The utility model relates to a flashlight for lighting, in particular to a flashlight with adjustable light.

Background technique

In daily life, the flashlight has become an indispensable tool for people. The existing dimming flashlights have disadvantages such as non-concentrated light, short service life, high manufacturing cost, and large power consumption. Therefore, how to invent a dimmable flashlight with low cost, simple appearance, energy saving and environmental protection has become a common task faced by flashlight R&D and production organizations.

Utility model content

The utility model aims at the deficiencies in the prior art, and provides a gear lens dimming flashlight with low manufacturing cost, simple appearance, energy saving and environmental protection.

In order to solve the above technical problems, the utility model is solved through the following technical solutions:

The gear lens dimming flashlight includes a head ring, a head frame, a lamp body and a lamp tail connected in sequence. The inside of the lamp body is provided with a rack, and the inner surface of the rack is provided with a gear. The gear is arranged on the gear shaft, and the gear It is toothed and connected with the rack, and the outer surface of the rack is equipped with a rack kit; the inside of the head frame is equipped with a lens, LED light-emitting diode, reflector and heat sink, and the heat sink is fixed on the rack by screws; the inside of the lamp body An electronic circuit board and a battery rack are provided, and the electronic circuit board is electrically connected to the LED light-emitting diode; the inside of the lamp tail is provided with a pressure ring, a spring and a leather cap, the spring is arranged between the pressure ring and the leather cap, and the outside of the leather cap is provided with The tail button, the bottom of the battery holder is connected with the tail button.

An O-ring is provided at the joint between the lamp tail and the lamp body.

The working principle of the utility model is: by pressing the tail button to control the mechanical switch on the battery rack, the battery rack is equipped with 3AAA batteries, the battery rack has a positive pole and a negative pole, which are directly connected to the positive and negative poles of the electronic circuit board, and the electronic circuit board leads out The positive and negative poles are connected to the positive and negative poles of the LED light-emitting diode to form a loop; the stretching and dimming is through the rotation of the gear, which drives the rack in the rack kit to move linearly, and the heat sink is fixed on the rack with screws , forming one body, solid and convenient to form a conjoined movement, when reaching a certain distance, the lens will act as a limit; when the rack is retreating, the rack kit will act as a limit for the heat sink when reaching a certain distance The role of this is a stroke of stretching.

The beneficial effect of the technical solution is that the relative position of the light source and the lens is adjusted by gears and racks to realize the effect of concentrating light, and it has the characteristics of convenient operation, good hand feeling, stable performance and long service life.
