What's the price of the LED light string?
- Frame and bottom plateLED panel light frame and bottom plate according to different material, its heat dissipation performance is not the same priceThere are differences. The price of the 6063 aluminum profile is about 50-80 yuan (the specifications are different and the prices are different).s
The top LED lights always burn the bulb in series
- If it is a constant current drive, there is a special adjustment element to adjust the current.s
Low voltage LED lamp string resistance is how to count, there is no formula?
- In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.s
What is the connection distance of the LED light string?Be specific
- When the installation must be installed according to the manufacturer's requirements, do not let the LED lamp string overload operation. I use the Zhongshan Greenman, which has detailed instructions, easy connections
What is the principle of the LED series?
- 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.s
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?s
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 problems
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)s
