FAQ

1-May I have your samples for existing items?

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 lights of the mobile phone as a flashlight, open for a long time will be bad
Not too long, long time will be hot, it is only emergency use only
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: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?
The batteries commonly used in the market for LED flashlights are lead-acid batteries, and their charging circuits are generally the simplest circuits with capacitive current limiting.
Q:LED flashlight batteries instead of cell phone batteries
Can you LED this flashlight, if the original is the use of a small battery, the voltage is generally about 4V, while the voltage is 3.7V mobile phone battery is fully charged when, 4.2V can be directly substituted.
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:Make a small flashlight with LED lights
If simple, buy a 1W or 3W lamp, a series resistor and slightly on the battery is good, the cement resistance of 12 ohms around 0.25W, 3 batteries of about 4.5V, the general lamp voltage of about 3.3V, can not be added directly on the battery. Standard can be two batteries plus step-up circuit approach, but you do simple, there is no need to be so troublesome.
Q:Would you please use the LED of a flashlight with size 5 batteries to make it glow with a No. 3 or 7 ordinary battery?
Use a LED with 5 batteries, and use a 3 or 7 regular battery to make it glow.
Q:LED lamp with what method from the welding of aluminum substrate nondestructive down (T6, flashlight)
Welding principle: the molten solder paste is formed by the heat transfer of the parent, and the solder paste is a paste body of M51 welding wire and M51-F flux according to a certain proportion.
Q:Does the general LED flashlight stop charging when it is full of electricity?
Will not stop, because it is designed for cost considerations, there is no full stop circuit, the general charge 8 hours, the charge has an impact on the battery, life is shortened, but it will not explode.
