0603 RGB Full-Color LED Price, Sales, Manufacturer, Phone Number [Nanjing Weishibo Electronics Co., Ltd.] 1. Voltage: LED beads use low-voltage power supply, with a supply voltage of 2-4V, varying with the product, so it is driven by a safer power source than high-voltage power, especially suitable for public places; 2. Current: Operating current ranges from 0-15mA, brightness increases with the current; 3. Efficiency: Consumes 80% less energy than incandescent bulbs with the same light efficiency; 4. Suitability: Small, each LED unit is a square of 3-5mm, allowing for various shaped devices and suitable for changing environments; 5. Response Time: The response time of the incandescent bulb is in milliseconds, while the LED's response time is in nanoseconds; 6. Environmental Pollution: Contains no harmful mercury; 7. Color: Changing the current can change colors; the light-emitting diode can easily be modified through chemical methods to adjust the band structure and band gap of the material, achieving multi-color emission such as red, yellow, green, blue, orange. For instance, at low current, the LED is red, and as the current increases, it can sequentially change to orange, yellow, and then green.
