LED Bulb Light 3W/5W/7W/9W/12W led bulb e27

Q:LED lights string broken, how to repair?: Connect the electricity. Can be shorted one by one. It's shining. This is just short of bad beads.

Q:Rated voltage of LED lamp string: You are the light string and see how much you a lamp, the lamp voltage for LED in 3.0-3.4V, for intermediate values of 3.2V, N=220/3.2=68.75 so many beads. In fact, we are in terms of LED is a DC device, there is no voltage rating, mainly to see his current value, the work must be steady flow. The power 0.06W LED current is 20MA, the power 0.2W LED current is 60MA, the power is 0.3W, the LED current is 100MA, the power is 1W, the high power LED current is 300-350MA, and so on in turn, ah, I=P/U

Q:The number of lights in the LED string: 15 lights, 30 lights, and 60 lights refer to the LED band. How many LED components are welded per meter length?

Q:220vled water lamp string how to connect, that is, 220 of the electricity: The triode acts as a switch in the circuit, and when the circuit is through, the left LED is first lit. The base is connected with a capacitor to connect the collector of the next triode.

Q:I want to do a string of LED lights that can use batteries. About 55 or so. The lights are 5MM blue. How can I work? Urgent urgent!!: If it is a general common blue LED working current is 20 mA, voltage of about 2.5V can be lit, the battery power can be used in parallel, the benefits of this connection is one of the damage does not influence the normal operation of other LED. And each LED string to a current limiting resistor, LED protection lamp, prolong life, calculation formula of the resistance for V / 0.02A=: voltage current resistance: 3V, battery powered =3 / 0.02=150. You want to supply 55 LED batteries to work together, the total current is up to 0.02x55=1.1A, i.e. 1AH (ah) capacity of the battery can work 1 hours or so.

Q:Led full-color light string and how to control wiring: 5 line DMX512 full color string, 2Po, 2 access, and access control site

Q:How do you connect the LED lights?: A series of even parallel. Are not clear, boss, you want to use LED do what?There is a gap, which is the positive pole of the LED (usually the long foot is short and the foot is negative)

Q:Section LED lantern, no controller, can shine principleTwo now reduced brightness string string: LED string:Light emitting diodes, referred to as LED, are made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.

Q:How does the LED light string flash?: What kind of light? What about the flash?If you are talking about the pulse drive mode of LED, then it is for heat dissipation and energy saving.

Q:The top LED lights always burn the bulb in series: A simple circuit based on resistance current limiting can only be adjusted with current resistance.
