LED lamp performance characteristics

1. Voltage: LED lamp beads using low-voltage power supply, the supply voltage between 2-4V, depending on the product varies, so it is a higher than the use of high-voltage power supply; safer power supply, especially for public places;

2. Current: Operating current 0-15mA, brightness with the current increases and brighten

3. Efficacy: consume 80% less energy than incandescent.

4. Applicability: very small, small pieces of each unit LED is 3-5mm square, it can be prepared into a variety of LED lamp bead shape of the device, and is suitable for volatile environments.

5. Stability: 100,000 hours, light failure is the initial 50%.

6. Response time: The incandescent lamp response time of milliseconds, LED lamp response time of nanoseconds.

7. Environmental Pollution: No harmful metal mercury.

8. Color: change the current can change color, light-emitting diodes easily through chemical modification methods, adjust the energy band structure and bandgap, blue and yellow orange yellow to achieve multi-color light. Such as small current red LED, with the current increases, you can turn into orange, yellow, and finally green.
