Q:How much is the voltage across the 20 LED lamps in series?

Don't know what kind of LED, if it is ordinary bright LED words, according to different colors, the rated voltage between 3.6-3.8V (current allowable level <20mA), you can be calculated according to the amount of estimates, as long as the control current should not exceed 20MA no problem

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

If it is parallel, how much is the number of parallel to you, such as your distribution of LED lamp lights inside the 12 series and 8 (0.2W), then use the current is 60X8=480mA

Q:LED lights string broken, how to repair?

LED lights string broken: you can check one by one, which is bad, which change.

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: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:The color temperature of LED light string

Light source temperature is different, light color is also different:The color temperature is below 3300K, the color is red, and gives a warm feeling. There is a sedate atmosphere and a warm feeling.The color temperature is in the middle of 3000--6000K, and there is no obvious visual psychological effect in this hue, and there is a refreshing feeling. It is called neutral color temperatureColor temperature exceeds 6000K, light color slants blue, give a person with cool feeling, commonly referred to as cool color temperature.

Q:How do you connect the LED lights?

Connect the bottom edge of the triangle symbol to the high voltage and the sharp angle to the low voltage. The bottom edge of the next LED is connected with a sharp angle

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

This advantage can be centralized control, inconvenience is unable to achieve a single LED light string lighting effect and switch control, which specific way can be measured by their own. I use the LED lamp string is Zhongshan Greenman with total power and parallel connected to

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

If you direct the transformer to the LED lamp power supply, the life of the LED lamp will be affected, far less than the nominal value.
