Powerful Flashlight Flashlight aperture
Flashlight manufacturers detail light flashlight small knowledge
In the purchase of light flashlight, we must pay attention: flashlight prices
Plastic flashlight to see the battery, LED life of about 10 years;
See the aperture, good LED flashlight aperture for a uniform circle, poor LED flashlight spot is divided into yellow and blue uneven distribution;
See the brightness, good LED flashlight high brightness, slow decay; see waterproof, good LED flashlight with waterproof function, good seismic performance, that is resistant to drop; look at the appearance of this more than I will see, I do not say, of course The vast majority of people will choose aluminum alloy shell, nice.
The biggest advantage of flashlight is the small size, easy to carry, power, large luminous flux, current is small, long life.
Depending on the characteristics and use of the situation, the flashlight has a different function
1, outdoor: If there are difficulties, can be used torch shot distress signal, flashlight price.
2, home: night can be lighting the room, easy to operate simple, easy to maintain
3, wild: in case of bad guys, wild animals, direct each other's eyes, self-defense can also be used in patrol, duty, work lighting, car, hunting and so on.
To say that LED applications in the flashlight, I am sorry to have to introduce the characteristics of the first LED:
1, LED long service life, generally up to 50,000 hours more than the traditional tungsten filament life higher than 5 to 10 times.
2, cold light, low heat, will not damage the lampholder high security.
3, the reaction speed, resistance to collision, small size, easy to small and lightweight.
4, energy saving, energy saving, new environmental protection light bulbs.
5, the reaction speed as long as 1us (microseconds), no warm light can improve safety.
6, low-voltage drive safety.
As a result of the above advantages, LED has been gradually applied to: backlight, traffic lights, urban lighting, car lights, general lighting. Here to introduce the application of high-power plastic flashlight. In recent years, with the high-brightness LED technology matures, the cost is also declining, a variety of different specifications of the high-brightness LED is also more commonly used in new lighting equipment. At present, this high-brightness LED applications in the flashlight, it can be said that the most suitable, because this high-brightness LED high efficiency, long life, light color pure. At present, can not create high-power LED, but the low-power LED is suitable for use in small flashlights such as flashlights.
LED flashlight is LED light-emitting diode as a light source of a mature application of lighting tools, it has a power, durable, strong brightness and so on.
