LED Flashlight Replace the traditional flashlight
LED flashlight is a light-emitting diode as a light source of a new lighting thing, it has a power, with the use of strong brightness and other strengths. Since the white LED available, it has now been introduced, but the beginning of time because of the low brightness of white LED, high cost, expensive offer ordinary people nobody cares, as long as some of the military on a small number of implementation.
With the progress of white LED brightness, the decline in capital, and gradually go such as the public team. At present, the European and American shopping malls have large quantities of high-power LED flashlight, LED offer with the further decline, now LED flashlight has been popular in the shopping malls, much to replace the traditional flashlight trend.
For example, a special high-power LED flashlight for outdoor use: Challenger - polar light Hight Power LED flashlight, Taiwan original authentic high brightness 1W LED (brightness up to 40 ~ 50 lumens) using constant current circuit planning, so that LED real Made of energy-saving, low power consumption, the service life of 100,000 hours, a group of batteries can be used 6 to 8 hours, the shell made of aluminum-magnesium alloy, the anode treatment, corrosion and wear, a strong anti-vibration ability, Structural planning, can be accustomed to outdoor harsh environment. Lamps use condenser planning, shine interval of up to 50 to 100 meters, but also manual dimming, to achieve the best condenser role.
How to choose LED flashlight accurately
1, the number of head, the number should be moderate. The home is usually not more than 12, the use of the battery in the 2 to 3 as well, and then a little bit of waste, for other special needs can be determined according to their needs. Of course, high-power Hight Power LED flashlight usually can not reach the number of 12.
2, see welding, welding to prison. Each diode is connected through the welding on the circuit board, if there is poor contact with the Weld, there may be the formation of electric beads does not shine or affect the use of all.
3, look at the battery, there are two types of batteries and lithium, although the lithium battery is rechargeable, but the low number of life, about 2 years, LED life of about 10 years, according to the actual situation to select
4, see the brightness, good LED flashlight high brightness, slow decay.
5, look at the bulb, bulb subsided case, the naked eye is difficult to distinguish it from good or bad, can be lit in the case of light bulb consistency.
6, to see waterproof, good LED flashlight with waterproof function, good seismic performance, that is resistant to fall. Because it belongs to the electronic products, flashlight in front of a circuit board, once the water prone to short circuit, the formation of damage.
7, look at the aperture, good LED flashlight aperture for a uniform circle, poor LED flashlight spot is divided into yellow and blue uneven distribution. Earthen polished surface as much as possible set a little. This flashlight is not like the general torch to adjust the focal length, purchase should be careful not to have astigmatism.
8, look at the appearance, to pick aluminum alloy shell, nice.
9, see the shape, according to the detailed use of occasions and useful, you can pick the appropriate size of the appropriate size of the flashlight.
