What are the characteristics of LED lamp beads?

time:Apr 08, 2022 Views:


1. Voltage: LED lamp beads use low-voltage power supply, and the power supply voltage is between 6-24V, which varies according to different products, so it is a safer power supply than using high-voltage power supply, especially suitable for public places.


2. Efficiency: consumes 80[%] less energy than incandescent lamps with the same luminous efficiency.

3. Applicability: very 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.


4. Stability: 100,000 hours, the light decay is the initial 50[%].


5. Response time: The response time of incandescent lamps is in milliseconds, and the response time of LED lamps is in nanoseconds.


6. Environmental pollution: no harmful metal mercury.


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 multi-color emission of red, yellow, green, blue and orange. For example, an LED that is red when the current is small, can turn orange, yellow, and finally green as the current increases.


8. Price: The price of LED lamp beads is relatively expensive. Compared with incandescent lamps, the price of several LEDs can be equivalent to the price of one incandescent lamp. Usually, each signal lamp needs to be composed of 300 to 500 diodes.
