Flashlights Use The Environment And Scope Sep 29, 2017

According to the environment and scope of the Flashlights, it has the function of lighting, intimidation, alarm and high pressure self-defense.

This multi-function Flashlights with high-pressure self-defense function, is synchronized with the alarm sound effect. If the criminals want to use the multi-function Flashlights in the high-voltage function of the crime, it will issue a loud alarm sound, no doubt the criminals are burned, so that restrictions on the criminals to buy multi-purpose Flashlights crime attempt.

For good people, with a multi-purpose Flashlights, regardless of day or night, walking in the rugged mountains or other places, encounter ferocious beasts or criminals, can be issued before the alarm to scare away, if the beast or criminals regardless of alarm sound on the good Attack or robbery, the good people can use high-pressure attack beasts or criminals, to achieve personal self-defense, at the same time, the loud alarm sound will also call around the rescue workers, it is multiple purposes.

In order to prevent the bad guys to buy multi-function Flashlights, the alarm part of the removal, leaving only the high-pressure part of the crime, in the design of the demolition of the alarm part of the high pressure will be invalid.

A typical Flashlights has a battery-powered bulb and focus mirror, and a hand-held handle for hand.

Although it was quite simple to design, it was late until the late 19th century was invented because it had to be combined with the invention of the battery with the light bulb. In the early years because the battery power is insufficient, so in English it is called "Flashlights", meaning a short lamp.

Environmental protection is better, the spectrum is not ultraviolet and infrared, neither heat nor radiation, glare small, and waste can be recycled, no pollution does not contain mercury elements, cold light source, you can safely touch, is a typical green lighting.

1. the number of moderate. Household generally do not have more than 12, the use of the battery in 2 to 3 as well, and then a little waste, for other special needs can be determined according to their own needs.

2. Welding is tight. Each diode is connected by welding on the circuit board, if there is poor contact with the Weld, it may cause the electric beads do not shine or affect the overall use.

3. Earthen condenser surface as much as possible to concentrate. This Flashlights is not like ordinary Flashlights can adjust the focal length, purchase should be careful not to astigmatism.

4. Power switch contact to be obvious. This type of Flashlights using rotary switch, tighten on the open, and then loose on the off, if the contact is not obvious, it is easy to cause when the phenomenon of light off.

5. Attention to waterproof. Because it belongs to the electronic products, Flashlights front has a circuit board, once the water prone to short circuit, causing damage.

Tungsten wire bulb + alkaline batteries, the surface of the metal plating for the first generation of Flashlights [3], commonly known as "old Flashlights", the bulb is generally used tungsten incandescent bulbs, luminous efficiency is low, shorter life, easy to burn The Batteries with large alkaline batteries, large capacity but endurance is not high. Flashlights shell for the surface of the metal plating, light but the process is simple.
