LED strong light flashlight inspection method and precautions for use
I. LED strong light flashlight inspection and maintenance methods:
1. Do not directly irradiate the eyes with light to avoid damage to the eyes.
2. Do not use overvoltage, the voltage should not exceed 4.5V, the positive pole of the battery is facing forward, do not reverse, otherwise it will burn the circuit board, pay attention to control the temperature change of the torch, non-professionals do not open circuit board.
3. When charging, please check the positive and negative poles of the electrical appliance, do not overcharge or overdischarge, so as not to damage the life of the battery, note: the rechargeable battery can not be exhausted, otherwise it cannot be charged!
4. When using the flashlight, check that each thread is tightened without loosening. If the threads are not tightened, it may cause no light or slight light.
5. Avoid placing the flashlight in the sun or high temperature environment. After the flashlight stops using, please take out the battery and store it in a cool and dry place.
6. This flashlight has the ability of waterproofing for daily life. Generally, there will be no problem in the rain, but it does not have the diving function. Do not carry this flashlight for diving or place it in the basin or bathtub for a long time.
7. In order to keep the “O” ring (sealing rubber ring) and the thread rotating smoothly, please wipe the Vaseline oil on its surface 2-3 times a year.
Note: If there is a flashlight with its own charging function, when charging, the indicator light of the charger turns from “red” to “green” to be fully charged. At this time, unplug the charger and stop charging. When charging, do not reverse the positive and negative poles (if you find that the light is insufficient, generally about 1/3 of the maximum brightness, please charge it immediately!), otherwise it may cause the flashlight to be scrapped (the positive pole with a “+” sign towards the head of the flashlight ). At the same time, please do not completely exhaust the lithium battery. If the brightness is obviously dimmed during use, it should be charged in time, otherwise it will easily lead to the battery being over-discharged and scrapped.
2. Matters needing attention when using LED strong light flashlight:
LED strong light flashlight products should be checked before delivery to ensure that there is no It will be shipped only after the problem occurs. Generally, there will be no problems. However, other factors may occur during transportation or improper use during use. There may also be individual problems. If the LED light does not light up, please follow the following methods. Preliminary maintenance:
1. Determine the fault: unscrew the tail to expose the negative electrode of the battery, use scissors or tweezers to connect the negative electrode of the battery and the exposed unoxidized part of the strong light flashlight next to the battery, and see if the point Bright. If yes, it is the problem of the strong light bulb switch, please check according to step 3; if it still does not light up, please check whether the soldering at the connection between the circuit compartment and the circuit board is open or weak. If so, please re-solder Solve the problem.
2. Check the battery: Make sure that the battery is charged and installed in the correct direction. Do not use different types of batteries, and do not mix old and new batteries.
3. Check the tail cover switch: unscrew the tail of the LED flashlight, you can see that there is a switch pressure ring with two concave points on the outer ring of the switch spring, use tweezers or scissors to connect the concave Turn clockwise on the point to check whether the switch pressure ring is loose, and ensure that the switch pressure ring is tightly pressed on the switch and cannot be loose.
4. Before maintenance, please make sure that all threads of the explosion-proof flashlight are tightened without loosening.
5. If the above method still cannot solve the problem, please return the strong light LED flashlight to the company, we will solve any problem or replace it, or you can contact the website customer service to return it, please write in the package when returning it A note indicating your recipient address, so as not to waste your precious time.
