Q:Can solar LED flashlights become a trend in the future?
At night, the electric energy in the storage battery charges the semiconductor LED LED for illumination. The system adopts full automatic operation, without manual intervention, can use sound, light or delay control mode, so that "people in the lights, the lights are turned off" (referring to the corridor, corridor etc.) or "dark light, delay lights" (referring to the road, courtyard, and other attractions) or the daily 24 hours "not very bright" (refers to the underground parking lot, tunnel etc.).
Q:Please master to help me identify what LED said, the more detailed the better, Pailide GL-K139q flashlight inside, not CREE.
The biggest advantage of domestic LED is cheap, city led is used to consider the cost, with many things must choose the cheapest price, I mean the flashlight used in LED is not used or decorative landscape lighting is led Oh, that few CREE, nobody knows that do not understand, does not mean that he is not good, not every field by the public know excellent brand too much, not public necessities flashlight is at most a fancier play, can say is a toy, so the number must belong to a small thing, than the number or the property of the country led up, if the price is CREE and domestic flat, so that the rate of CREE use more domestic than to be sure, of course to exclude domestic manufacturers through bribery of government departments or unfair competition order
Q:The Led flashlight has been charged for a very short time. Is there something wrong with the battery?
Most of the causes are battery problems, thank you
Q:What about the flashlight bulb? Which kind of brightness will be higher?
Good to the number of beads flashlight flashlight lamp, flashlight and now basically use the CREE company of the United States beads. Commonly used according to brightness from low to high: Q3, Q5, R3, R4, R5, T6, U2.
Q:How to install the LED flashlight lamp in the reflecting cup.
The general flashlight has a special lamp bin (seat) the lights installed (with beads coated with substrate under), thermal grease inside the lamp, bin (seat) on the circuit board, then the following is.If I had to put it on the reflector, I didn't have it, but the truth was the sameThe lamp lamp based directly on + radiating silicone adhesive in the cup, cup has two holes to walk the line, the circuit is arranged outside the lamp cup
Q:Cree flashlight lamp which is the best.
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:LED rechargeable flashlight, small table lamp
The voltage between the 2V-2.6V is the lead-acid battery.Voltage at 3.6V-4. Between the 2V is the lithium battery.Generally speaking, charging more than time will cause serious damage to the battery, because the low charger does not automatically protect the battery. So, it's better to press the instructions.The light of the rechargeable flashlight sometimes shakes, probably due to poor contact between the switches and other parts. It can be checked by itself.The battery that has just been charged has the highest voltage, so the light is brighter, and as the energy consumption, the voltage will gradually decrease, so the lights will dim. In low level lamps without a stabilizer, dimming is normal.
Q:How can a rechargeable flashlight LED light bulb be judged by a multimeter?
Upstairs said yes, pointer multimeter, with 10K files, you can also use mobile phone batteries, the number of connected, on the bright, the wrong connection is not bright, how to connect also does not light, that is broken, this light is afraid to turn on the lights when the power.
Q:Is led flashlight used widely?
LED flashlight is using high brightness light emitting diode as the light source, it has the advantages of high brightness, low energy consumption, environmental protection and energy saving, the use of long, generally applicable to mountain climbing, hiking, camping, riding, hunting, fishing, rescue, patrol, cave exploration, mining, homemade daily usage.
Q:At present, the LED flashlight commonly used in the market, the built-in lead-acid battery is too bad, can use 4 nickel hydrogen rechargeable battery instead?
Its battery life is short, mainly due to charging circuit caused. At the same time, the lamp component is current limiting resistors, greatly influenced by voltage. The current limiting resistor is selected according to the 4V voltage. When the voltage becomes higher, lamp current will increase obviously. When used instead of 4 Ni MH battery when the battery voltage is 4.8V, current lamp is much greater than 4V, so the lamp of life is very short. At the same time, because the charging circuit design is very unreasonable, the battery life is also very short.
