LED Globe Lamps-12W LED Bulb,CHINA MANUFACTURE.

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

Q: Led full-color light string and how to control wiring: Three line full color exposure lamp data signal two, the controller needs two wire negative electrode control, GND signal connected to the DAT surface

Q: 220vled water lamp string how to connect, that is, 220 of the electricity: The triode acts as a switch in the circuit, and when the circuit is through, the left LED is first lit. The base is connected with a capacitor to connect the collector of the next triode.

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: 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: 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: In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.

Q: LED lights string broken, how to repair?: LED lights string broken: you can check one by one, which is bad, which change.

Q: What's the price of the LED light string?: Light guide plate and diffuser plateLED panel lamp manufacturer's production line price is probably between 60-80 yuan (12 pieces). The quality of the light guide plate is one of the most important factors determining the quality of the LED panel lamp. The use of high-quality light guide plate can make the finished LED panel light more uniform. No dark spots, ripples and so forth

Q: How much is the voltage across the 20 LED lamps in series?: LED lighting general LED lamp belt voltage, conventional specifications are 12 volts and 24 volts, if it is 12 volts, that voltage is 420 volts, if it is 24 volts, that is 840 Volts

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
