Q:Charging time of LED rechargeable small flashlight
But don't wait until it's completely dark. This is deadly!
Q:How much is the price of the SF007 LED explosion-proof flashlight on the high beam?
The market price is 447 yuan, the cost is about 40 yuan, and the battery is about 8 yuan. The service life is not ideal. If the switch is rotary, it is easy to oxidize inside.
Q:Led what's in the battery in the mini rechargeable flashlight?
High power LED flashlights generally use lithium batteries or alkaline batteries or nickel hydrogen batteries.
Q:High power flashlight LED lamp is 1W, want to use mobile phone battery when 4.2V is connected to electric drums!
Yes. No need to connect in series. Your voltage is not enough after series connection. If you have two batteries in series, your voltage is about 6.6V. Add a resistor directly to OK. (4.2-3.3) /0.35 = 2.57 on the line. You can use 2-3 euro, at this time the current is almost between 300MA and 400MA, there is no problem.
Q:How long has the LED flashlight been in use?
The larger the battery you use, the longer it will last. The smaller the capacity, the shorter the use time.
Q:How to fix a flashlight?
When the flashlight is not shining, remove the lamp holder and check the lamp holder and cylinder. If there is no problem with the bulb, it may be that the copper in the switch is rusted. Take a pair of scissors and insert into the two small eyes of the front cover. Remove the front cover and scrape away the rust on the copper sheet with a knife.
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:What's the use of a bright flashlight driver?
Because if the battery drives LED directly, the voltage and current of the battery will decrease gradually, which will cause the instability of the light.
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.
Q:LED rechargeable flashlight, small table lamp
First of all, you should find out what kind of battery you use, and then decide what method to charge the most reasonable. After you know what the battery is, you can check the correct charging method on the Internet
