1. Voltage: LED light beads use low-voltage power supply, which varies according to different products, so it is driven by a safer power supply than high-voltage 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: The size is small, each unit LED chip is 3-5mm square, so it can be prepared into various shapes of devices, and is suitable for variable environments.
5. Response time: The response time of incandescent lamps is milliseconds, while the response time of LED lamps is nanoseconds.
6. Environmental protection: No harmful metal mercury, no pollution to the environment.
7. Color: Changing the current can change the color. The light-emitting diode can easily adjust the energy band structure and band gap of the material through chemical modification methods to achieve red, yellow, green, blue, and orange multicolor light. For example, a red LED at low current can change to orange, yellow, and finally green as the current increases.
