is the LED's forward voltage drop in volts when lit. and the LED's light frequency (which we perceive as color) increase with the band gap of the LED's materials. Consequently, ranges from around 1.7 to 2.0 volts for red LEDs to around 2.8 to 4.0 volts for violet LEDs.
1 watt 9 volt three chips SMD phosphor based white LED. Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stokes shift loss.
Voltage: Rope lights in the United States are generally sold in three different voltages: 12 volts, 24 volts and 120 volts. Generally, the 12 volts and 24 volts variants are better suited for situations where a battery is used to power the lights. Hence, this is the best option for cars, boats, etc.
The voltage of the power outlet is usually near 12 V DC, and may be elevated between 13.5 V to 15 V while the engine is running. On trucks, the voltage of the power outlet may be near 24 V DC. The 12 V power circuit is protected by a car fuse, often rated at 10 to 20 amperes, which provides 120 to 240 watts of power. Large appliances such as ...
