FAQ

What about the high brightness of a flashlight? Bull LED? Or single head high power LED? That kind?

At present, there are still a lot of brightness need to be observed on the market. The main thing is to rely on your own eyes or measure together. However, in the case of the same total power (such as 1W), multiple small power heat generation will be greater than a single high-power heating capacity. The reason is very simple, now all the conductors are not super conductor, there are resistance, since the resistance, the efficiency of electricity will not fully utilize the 100%, will certainly have the energy loss in the heating wires above, so the more long more heat is inevitable.

LED flashlight, how many V and how much W is it related to?

Usually the letter "U" stands for voltage, and the unit of voltage is "volt", referred to as "volts". The symbol is "V."When voltage is very high, kV is usually used as a unit. When voltage is low, mV is used as a unitW (Watts) is the unit of powerPower * time is power consumption

How to judge whether the constant current chip Led flashlight?

The simplest method is whether the brightness changes during the first half of the observation battery discharge, constant current chip of the first half is the same brightness, such as 7135, dark in the relatively low battery voltage later. If it is the whole constant current design, only when the battery is about to be finished, the brightness will decrease rapidly.

How to measure the circuit board of LED flashlight with Multimeter?

Measurement of resistance, in the selection of the appropriate rate of stalls, two pens together so that the pointer refers to zero, such as pointer deviation from zero, regulation should be "zero" knob, the pointer to zero, to ensure accurate measurement results. If you can not adjust the zero or digital display issued a low voltage alarm, should be promptly checked.
