Flashlight is one of the very practical daily necessities. Especially in outdoor activities, flashlights are also indispensable practical tools. In addition to being able to illuminate the surrounding environment at night, there are many types of flashlights.Its not the same. How can we distinguish the flashlight and choose a practical and durable flashlight?Lets take a look at the editor.
How to maintain a flashlight
1. The flashlight adopts advanced voltage voltage constant current technology, which can effectively solve the requirements of LED flashlights on the constant stream flow;
2. Special prompt:
Do not use it over voltage, do not exceed 4.2V;
Do not reverse the battery, otherwise it will burn the board;
Pay attention to the changes in the temperature of the flashlight and ensure the heat dissipation;
Non -professional, please do not open the line board;
3. Warranty description: The burning plate or burning light no longer warranty range; open or handle the range board no longer warranty range.
5. Lithium battery characteristics: The charging method of lithium batteries and mobile phone batteries is completely different; lithium batteries are not memory, and they can be charged at any time at any time without charging;
6. Fast slowly according to the charging of the charger, take it out as soon as possible after the indicator light changes.
7. When the natural discharge rate of lithium batteries is not used, it will release about 1% or less every day. Although slow, the anti -release time is too long;
8. Pay attention to the waterproof, moisture -proof, anti -drop, etc. of the battery;
9. Special reminder to use the "three -defense" charger with anti -charge, anti -roll -up, and short circuit;
10. If the battery is not used for a long time, the power should be fully saved, and it should be charged again at about three months.
How to choose a flashlight
Selected material
If you want to pick it up, you must first choose the material of the flashlight.
Tube body material: The plastic material of the flashlight body is not durable, and the stainless steel is sturdy and durable. However, after long -term use of stainless steel, it is also easy to be oxidized, causing the flashlight to be unavailable normally.Therefore, it is recommended that you buy a flashlight with titanium alloy or high -strength carbon as a tube body.
Material of the lens: It is best to use the material of high -strength optical glass or polycarbonate, which not only has good permeability, but also is not easy to wear.Do not choose ordinary glass or organic glass for lens materials. Ordinary glass is fragile and organic glass is not wear -resistant.
Reflective cup material: First of all, it must be metal material.Because the high temperature resistance of metal is better.In addition, in order to ensure that the reflective performance is more guaranteed, we must observe the smoothness of the reflector cup. Do not buy scratches and spots on the surface.
Checketer
First of all, the body must be regular, detailed, and well -worn, without welding joints and gaps, which is essential for ensuring the moisture -proof performance of flashlights.Secondly, there must be non -slip and stubborn body, and the craftsmanship must be sophisticated.The third is that there should be a sealing ring at the connection between the lamp head and the tube body.
Discern source
The most common light sources of flashlights are two types of light bulbs and LEDs.Households can choose LED light sources. The advantage of LED is the phenomenon of power saving, long service life, and no excessive heat can produce "hot -handed".
Brightness
If it is only used indoors, a LED flashlight with a power of 1W is sufficient. The unsatisfactory AA battery is small. The current of the LED end is generally below 300mA and the power is below 1W.If it is occasionally used for outdoor, it is not recommended to use a dry battery flashlight. It is best to use 18650 tube, the current reaches 750mA, and the LED consumption power reaches about 3W.
Types of flashlights
1. LED ultra -long service life can generally reach 5-10 times higher than the traditional tungsten lamp life.
2. Cold light, low heat, will not damage the safety of the lamp holder.
3. Fast response speed, punching, small volume, easy small lightweight, etc.
4, power saving, energy saving, new environmental protection light bulb.
5. The response speed is only 1US (microsecond), and no warm light can improve safety.
6. Low -pressure driver safety.
At present, various types of lighting are used in the market. There are mainly plastic flashlights, LED flashlights, iron flashlights, aluminum alloy flashlights, stainless steel flashlights, hand -shaking flashlights, environmentally friendly flashlights, electric mosquito flashlights and other types.Here we focus on the classification of LED flashlights.
The current common LED flashlights include small keychain type, multi -lamp head, single -light head high -power type, etc.From the perspective of the type of power, some use a AA battery or a AAA battery, some use three AAA batteries, some use three button batteries, and manual power generation.
