Q:How much is the voltage across the 20 LED lamps in series?
Each LED is about 3V, and the 20 series is 60V
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)
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.
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:What is the principle of the LED series?
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: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: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
Refers to a standard blackbody heating, the temperature rises to a certain degree when starting from the color red - Orange - red - white - blue, gradually changed, a light source and the blackbody with the same color, we will at the time of the absolute temperature blackbody called the color temperature of the light source.
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:Led full-color light string and how to control wiring
Four line color data signal exposed lamp connected: lamp electrode with GND surface control signal is connected with the DAT clock with CLK
