Q:LED light resistance, I use flashlight LED lights plus resistors used in the 12V circuit can be used for a long time?
If only a single LED lamp and resistor, so voltage resistor consumes basically is 12-3=9V, working current of 60mA lamp, then the power loss of resistance to 0.06x9=0.54W, so the use of least resistance power must be above 1W, but this power is part of the battery discharge current limiting resistance loss, fever will be great
Q:What are the LED flashlight bulb?
Flashlight with beads. What do you look at the level slightly, generally cheapest are those with high imitation LED lamp, high power flashlight better are mainly domestic large power LED lamp is cheap, the quality is good, the use of imported LED, such as the U.S. CREE, South Korea's SSC, as well as Nichia LED and so on.
Q:LED electric drive circuit principle diagram, analytic find more straightforward
Process control diagram transistor mainly occurred in VT1, the work process is as follows, the capacitor connected to the VT1 on the left base potential basically fixed, when the VT2 is switched on, the capacitor potential decreased, because the capacitor voltage can not have a mutation, so as the drop-down role for VT1 base, this action prompted VT2 more saturated conduction. During the process, the capacitor is charged full, so that the base current of the VT1 is weakened. Then the collector potential of VT2 increased, the trend of the rise of the feedback base potential effect of VT1 capacitor is increased, which led to the rise of VT1 transistor appeared off, it causes the VT2 cut-off cut-off, inductance coil form boost, resulting in two transistor boost completely off, thus completing a shock cycle.
Q:Led strong flashlight batteries, how are they true and false?
There is no true or false, haolai, lead electric lithium, lithium electric lead two voltage is high, full of lithium 4.2V, lead 4.6V, also connected to the load voltage, voltage drop of battery differential
Q:Led flashlight, section seven, No. 3 battery for 3,7V lithium battery. What type do you need?
There is no limit, mainly voltage problems, the 3 Section 7 battery voltage is 4.5V in series, and the lithium battery voltage is low, but the current is generally applicable to led flashlight.
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 are the categories of LED flashlights?
The number of lamp caps (i.e., LED) ranges from 10 to twenty or thirty, with more than more than 40 lamps. Most of the shell of the torch is made of aluminium alloy. The switch of the torch is set at the tail part, and some are arranged on the side of the front part. The front side switch is more convenient to use. The ignition voltage of high brightness LED about 3V, so the LED flashlight uses three AAA batteries without booster can be directly lit, so the power supply efficiency is high, only a small energy consumption in the current limiting resistor. It should be noted that not the more LED, the better. Qi Jie automotive supplies experts advise, but also pay attention to see if there is a better quality reflector film behind the lamp cover, it can reflect the light scattered by LED, and can improve the brightness of the flashlight 20%~30%. The main disadvantage of the multi burner flashlight is that the focusing effect is not good, and the spotlight effect is not better than that of the ordinary flashlight, so that the light is not bright enough when irradiated on a far distance object.
Q:The flashlight is not T6 lamp is the best?
Is the no brand LED lamp judgment. First of all we can LED beads package process, and the brightness of the light and look at the level of purity. Is not very bright, or color is just not very good LED beads.
Q:Is it necessary to bring a LED flashlight for outdoor activities?
Do not use the old "tiger" tin or the kind of cheap plastic flashlight, flashlight, the flashlight is not waterproof, tin not falling, and large volume, inconvenient to carry, can not meet the requirements of outdoor activities
Q:Simple LED flashlight schematics, principles and components?
This is the simplest LED flashlight circuit diagram
