Introduce the Characteristics of Punched Character Beads

Issuing time:2019-01-05 00:00

First, color: Changing current can change color. Punched luminescent beads can be chemically modified to adjust the band structure and band gap of materials to achieve red, yellow, green, blue and orange multi-color luminescence. If LED is red at low current, it can turn to orange, yellow and green at one time with the increase of current.

Voltage: Using low-voltage power supply, the supply voltage is between 2 and 4 V, depending on the product, so it is a safer power supply than using high-voltage power supply, especially for public places.

3. Response time: The response time of incandescent lamp is millisecond, and that of LED lamp is nanosecond.

4. Environmental pollution: no harmful metal tribute.

5. Current: The working current is between 0 and 15 mA, and the brightness increases with the increase of current.

6. Efficiency: Energy consumption is 80% less than that of incandescent lamps with the same light efficiency.

7. High applicability: very small, each unit of LED chip is 3-5mm square, so it can be prepared into various types of bead-shaped devices, and suitable for the changeable environment.

8. Stability: 100,000 hours, optical decay of 50% of the initial.
