LED Flashlight Through The Circuit Adjustment

LED Flashlight Through the circuit adjustment

LED flashlight basic principles: flashlight by the luminous body, battery, circuit, shell, reflective cup, circuit box, switch and other components, the basic principle is the current from the battery out, and then arrived at the circuit, through the circuit to adjust the voltage and current, and then output to the luminous body , To light the lighting.

 LED flashlight with the luminous body are: LED, halogen lamps, usually bulbs and xenon bulbs (sub-tungsten wire filled with xenon and only filled with xenon HID), etc., other flashlight is not commonly used in this light is not said. As for me here that the brightness of each LED unit unified lumen (Lumens) marked, that is usually said that the luminous flux.

        Recently, the most popular is the LED, the Chinese full name is "light-emitting diodes", low-power LED is usually used in the 1AA or 3AA, I will not say that the power is too small, the family can, But the field is much worse, the first talk about the use of more than 3W field power, the main representative is currently the most popular is the United States CREE LED, long life, according to the manufacturer data up to 100,000 hours.

    (1) P3, 350mA Brightness 73.9-80.6 Lumens, 700mA Brightness 119.7-130.6 Lumens (2) P4, 350mA Brightness 80.6-87.4 Lumens, 700mA Brightness 130.6-141.6 Lumens (3) Q2, 350mA Brightness 87.5-93.9 Lumens, 700mA Brightness 141.6-152.1 Lumens (4) Q3, 350mA Brightness 93.9-100.4 Lumens, 700mA Brightness 152.1-162.6 Lumens (5) Q4, 350mA Brightness 100.4-107 Lumens, Maximum Current 1000mA (6) Q5, 350mA Brightness 107-114 Lumens, the maximum current of 1000mA (up to 220-250lm)

    LED flashlight is a light-emitting diode as a light source of a new lighting tool, it has a power, with the use of strong, and other advantages. Since the white LED available, it has now been introduced, but at the beginning of the white LED because of low brightness, high cost, expensive offer ordinary people nobody cares, only some of the military on a small number of implementation. With the progress of the brightness of white LED, the cost of decline, and gradually walk the ranks of the public.

    At present, Europe and the United States market has been large quantities of high-power LED flashlight, LED offer with the further decline, now LED flashlight has been widespread in the market, 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 anodized, anti-corrosion 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.
