Q:What's the average luminous current of an ordinary LED lamp string?

General LED patch to 0.2W, 0.5W, 0.2W lamp current is 60mA, 0.5W beads 150mA,

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 time of the water lamp is controlled by adjusting the capacity value of the capacitor.

Q:What's the price of the LED light string?

The power supply is also the most important factor affecting the price of LED panel light. The power is not good, directly affect the LED panel lamp life. UL power supply performance is relatively stable. The price is about 53 yuan, TUV power supply price is about 33, and other CE power supply.

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!!

You can use the 4~6V battery, through the 4W, 2~3 Europe (6V with 3 Euro, 4V with 2 Euro) current limiting resistor, to the LED lamp power supply. The parameters of each lamp are: 3V, 20MA, in parallel (polarity). If you don't quite understand, you can also ask a science and engineering student (preferably a teacher) to help.

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:How does the LED light string flash?

LED because of its special structure, frequent startup does not reduce its service life, but high temperature can significantly shorten its life. So cooling is important for LED.

Q:What are the power connections for the LED light string?

LED lamp string power connection method: LED light string, general voltage is DC 12V, so need to use switching power supply, power supply according to the size of LED light string and connection length to decide

Q:Example: if I want to do a 40 head low voltage lamp string, do 10 lights, 1 loop, transformer is 150MA, then how can I calculate the resistance? The grid is 60 Hz of China's power grid! Give a formula, and then count the examples. What is it?! Thank you

In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.

Q:Performance and characteristics of LED lamp string

1.LED lamp string can handle perforation lamp string processing;2.LED lights string may through seven colors and full-color controller to achieve colorful jump, gradient, monochrome, full-color, fluttering and other effects.
