Powerful Flashlight Condensation effect is better
Powerful flashlight features
Powerful flashlight refers to the use of a power of 3W ~ 10W single LED light flashlight. The biggest advantage of this powerful flashlight is better condenser effect, but still depends on the torch of the production of the mask is fine. Manufacturing more formal single-lamp powerful flashlight, the condenser effect than ordinary flashlight brightness even higher. Focused beam, strong penetration: can be very low in the visibility of the strong ..
Powerful flashlight refers to the use of a power of 3W ~ 10W single LED light flashlight. The biggest advantage of this powerful flashlight is better condenser effect, but still depends on the torch of the production of the mask is fine. Manufacturing more formal single-lamp powerful flashlight, the condenser effect than ordinary flashlight brightness even higher. Focused beam, penetrating power: in the visibility of very low fog, smoke, car glass case, illuminate the target. Can be widely used in outdoor sports, emergency, fire. Hunting, search, search evidence, conference briefing beam instructions. Powerful flashlight tube body using high-quality aviation aluminum metal, the surface plus hard anodizing, high hardness, will not rust, to ensure good performance of various parts of the product, durability 100%. Direct drive circuit current is not controlled, when the battery power is high enough time, the battery will do everything you need to supply LED, the flashlight will be very bright, the temperature rises in vain, heat and heat can not get a balance. To the battery gradually depleted after the brightness and temperature will slowly decline, this circuit due to pre-power is too high, the LED and battery damage is very large, lED life is often unable to achieve the design life, the battery will be overloaded working life shorten. This "quick success" of the flow of the drive program, only low-end flashlight will see. And for the long-range significance, in the early work of long-term effect of flashlight will be better, with the advance of time, long-range ability will rapidly weaken.
Constant current drive current, is the current mainstream drive program. The circuit will control the current supplied to the LED, so that the current is always maintained at the same size, for example: XM-L T6 with 2.0A constant current drive, the brightness is always maintained at 700 lumens. After the current constant current, flashlight and heat are also balanced, the battery output current can also be maintained. This is the optimal driver solution. General small size of the flashlight can be balanced about 15 minutes. Long-range effect can be maintained consistently.
Color temperature, the current LED is generally divided into cool white, white (white), warm white three color temperature. Cool white color temperature is highest, color is not good, in the flashlight industry is rare. In the white (white) color is good, highlight the brightness, is widely used. Warm white color temperature is the lowest, color is better than the white (white). In the long-range shoots the better the color of the LED, in the rain and fog, dust environment, the more able to reflect the penetration, low color temperature LED in the ultra-long distance is still able to see the object. Principle with the car lights, car headlamps on the fog environment is basically useless, and light yellow fog light can better penetrate fog.
