Q: The top LED lights always burn the bulb in series: If the regulator is powered, it is necessary to lower the voltage

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: The number of lights in the LED string: Different LED number of LED light band price is different, and this is also to distinguish LED lamp belt price is an important factor.

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: Performance and characteristics of LED lamp string: The 1.LED light string is led by a light emitting diode packaged in an imported chip;The design of light angle 2.LED lamp string of the larger angle angle of >120 degrees, uniform mixed color, no color;3.LED lamp string selected LED dedicated constant voltage power supply mode, circuit design for constant current circuit, the work performance is very stable, so as to ensure normal life >5 hours;

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: 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: Diode products cannot be calculated by resistors.

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 is the connection distance of the LED light string?Be specific: The connection distance is 15 meters. If the connection distance is exceeded, the LED light string is easy to heat, and the service life of the LED light string will be affected during use

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
