- Q: What's the function of LED violet flashlight? Does anybody know that?
- The main use of the violet flashlight is to test whether it contains fluorescent agents. Daily can be in the identification of banknotes, check clothes, paper, diapers and other fluorescent agents are included.The brightening and brightening effects of fluorescent agents have been widely used in many fields such as textile, paper making and washing. The relevant national standards also allow manufacturers to add fluorescent agents within the specified range. Parameters of the purple torch is indeed able to detect clothing, paper and other items contain fluorescent agents, but can not determine its content.
- Q: In the light rechargeable flashlight is how much?
- The terminal voltage of PN junction constitutes a certain barrier. When the forward bias voltage is applied, the potential barrier decreases, and the majority carrier in the P region and the N region diffuse to each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons will diffuse into the P region, which will result in the injection of minority carriers into the P region. These electrons are combined with holes in the valence band, and the energy is released in the form of light energy when combined. This is the principle of PN junction luminescence.
- Q: Why should a bright flashlight use a 3.7V battery, and why not?
- At present, in addition to LED light source, bright flashlight, as well as special lighting HID xenon torch, such as the current domestic brands have CSH-X01/02 (uscamel) design and manufacture of a series of super light flashlight. Strong light flashlight is a new type of lighting tool which uses LED as light source. It has the advantages of saving electricity, durability and brightness. Common light flashlight is a kind of outdoor lighting tool which uses high-power light-emitting diode as light source. It has the advantages of electricity saving, durability and high brightness. Cap LED flashlight with two light, a condensing cup condenser, a convex lens, condensing cup condensing effect is good, the light loss is small, light weight, can put the lamp holder part of the seal is very strict, improve the waterproof effect, the spot is in want of perfection is not adjustable, so that the use of it is near the illuminated area is very small, but the biggest advantage of stepless convex lens is the spot size can be adjusted, but it is difficult to achieve good waterproof, so the general outdoor sports enthusiasts will choose the former according to the environment. Power flashlight for rechargeable lithium ion batteries or nickel cadmium battery capacity, rated voltage 3.7V, ranging from hundreds to thousands of Ma, according to the common power source LED, endurance range in tens of minutes to several hours.
- Q: How many watts of LED light flashlight is there in Section 5, battery 3?
- The pocket flashlight below 10CM is generally used with 1-3W's LED, while the larger ones are typically in 3-5W, or even 10W LED, and a little bigger, using a multi section 18650 battery flashlight, you can use 20-50W's LED. I am a flashlight made of titanium lighting, the current effect of relatively strong flashlight, mainly with matching...
- Q: LED flashlight off the ground, it is not enough electricity, what happened?
- Maybe it's a short circuit. I'd like to buy a good quality tank007 flashlight
- Q: Flashlight LED one super bright, how many volts?
- See the lamp and brand. The most commonly used CREE L2 series are the most 3V, the CREE R5 series, up to 1.5V. These brands can find accurate parameters on the official website of LED.
- Q: What are the models of ultra high brightness LED on flashlights?
- Other LED, such as quad core P7, LED, SSC produced, 900 lumens, in the flashlight on the application of quite a lot, there are some other LED, not one by one to repeat it.
- Q: What's the resistance on the LED flashlight?
- If 5 heads, the working current is 5*20mA=100mA=0.1A, the voltage at both ends of the resistor is 3-0.7=2.1V, so the resistance power is 2.1V*0.1A=0.21W., so the power of the resistor is 1/4W.From this, you can calculate the resistance power of 7 heads and 10 heads
- Q: Charging time of LED rechargeable small flashlight
- This torch must be used with a nickel chromium battery and a slow charge circuit. It is recommended that LED begin charging when it becomes dark, usually 5~12 hours. For nickel chromium batteries, charging time is not too demanding, even if the overshoot energy will become heat loss, the battery will not cause any fatal harm.
- Q: How to design a flashlight spotlight with multiple LED lights
- Generally speaking, a LED lamp flashlight has two kinds, one is the micro light straw hat LED, lens angle of the LED itself is small, light cup again two is generally not focused, high power LED long, this is each LED within a single small reflector, surrounded by a large reflective cup, cup light but the effect is not very good, so the total effect, while in close range shooting ability is relatively poor brightness good, but not with large caliber single lamp deep LED flashlight than long-range.
