- 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.
- 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: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:How do you connect the LED lights?
- LED lamp can string together end to end, with more than 24 fluorescent lamp series, bulb lamp with 5X1W5 lamp series, and 6 series and 14.
- 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: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:Section LED lantern, no controller, can shine principleTwo now reduced brightness string string
- When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
- Q:Why are there three lines for the controller of the LED light string? What are they?
- Common positive (red line +) is the positive pole for each street lampThree road cycling (blue line) this four lines are respectively connected with the four colors of LED tube anode side run. When the positive pole is connected to the common cathode, remember that the resistor must be connected first to connect to the positive electrode of the LED tube. The bright output (white) is the word to make it bright
- Q:How does the LED light string flash?
- Because of the special volt ampere characteristics, LED can not use constant voltage driving mode, but is driven by cross flow. The direct drawback of cross flow drive, however, is heat. So people invented the drive mode of pulse drive. For example, 0.5 seconds per second, so that the amount of heat in the LED is reduced by half. Then turn the frequency up to 100 times per second, lighting for 0.005 seconds each time. At this point, the power of the LED is not the same, and people do not feel blinking. What's more, in this driving mode, an approximate cross flow drive (that is, the current is not necessarily precise) can be simplified, which simplifies the drive circuit (the precise cross flow source is very complex)
