1. Voltage: LED beads use a low-voltage power supply, with a supply voltage between 2-4V, which varies depending on the product, so it is driven by a higher voltage power supply; A safer power supply, especially suitable for public places;
2. Current: The working current is 0-15mA, and the brightness becomes brighter as the current increases
3. Efficiency: Energy consumption is reduced by 80% compared to incandescent lamps with the same luminous efficiency.
4. Applicability: Very small, each unit LED chip is 3-5mm square, so it can be prepared into various LED bead shaped devices and is suitable for variable environments.
5. Response time: The response time of incandescent lamps is in milliseconds, while the response time of LED lamps is in nanoseconds.
6. Environmental pollution: No harmful metal mercury.
7. Color: Changing the current can change color, and light-emitting diodes can be conveniently modified through chemical methods to adjust the energy band structure and bandgap of the material, achieving multi color luminescence of red, yellow, green, blue, and orange. If the LED turns red at low current, it can turn orange, yellow, and finally green as the current increases.
