- Q: LED flashlight instead of direct plug in power lighting
- Change block power well, flashlight power is DC low voltage power supply, home power is 220V AC power supply is fundamentally different
- Q: Skyfire LED flashlight and probe the dew
- 1. PT40 is a portable high-power XML U2 flashlight, brightness of up to 1000 lumens, the volume of moderate, suitable for military police, search, outdoor, camping and other occasions2. strong endurance to meet your long time lighting demand3. tactical tail switch, easy to operate, beautiful and durable4. specially designed mirror aluminum alloy high efficiency reflector cup, the spot is even and perfect5., the scientific design of the structure, exquisite workmanship, impeccable6. constant current circuit design, brightness constant
- Q: How many lumens is the 35W LED flashlight?
- LED can now do about 90 lumens, 35 watts per watt, or 3150 lumens
- 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: What's the difference between a LED flashlight and an ordinary light bulb flashlight?
- In brief, the LED has high luminous efficiency and convenient dimming.At the same power, the LED is much lighter than the incandescent bulb.At the same brightness, LED saves much more power than incandescent bulbs.
- Q: Flashlight, bright lights, led charging, which is good?
- The flashlight Market is deep water, if asked for it best according to their own requirements to buy parts together, if it is bought just buy a regular domestic factory in line with the use of words, the mountain "Shenhuo" it is best not to use.
- Q: LED flashlight MH7303 how to achieve explosive flash function, there are circuits as follows, but that is, can not achieve detonation flash!
- There are a lot of LED flashlights on the market now, the bare boards and finished boards are very cheap, so you don't have to develop them yourself,
- Q: 800LM flashlight, what power LED lights do you need?
- The flashlight to send the total luminous flux of 800 lumens, according to the current highest technology bulb, a luminous flux of 5 Watt LED lamp can get 800 lumens, the high power CREE light source package, Cree XML-T6 1C 800-1000LM high power white LED has achieved mass production
- Q: Why is the bulb of the LED flashlight only two bright?
- LED is a light emitting diode as the working voltage of general flashlight LED is about 2~3V, the working current of about 20mA, the maximum voltage flashlight can provide only about 12V, so LED is two a series with a current limiting resistor. Only two of them are still bright. It is possible that the rest of the LED is broken down or the resistance is aging. The resistance increases and the rest of the LED is not bright.
- Q: How long can a LED rechargeable flashlight last?
- It depends on how many flashlights you bought! The full charge of the three bulbs can be used continuously for more than 8 hours! The continuous use of four bulbs in about 6 hours! Of course, if it's a big flashlight, it's different. What I'm talking about is an ordinary flashlight (about 20 centimeters long).
