What are the characteristics of light-emitting diodes?
1. Voltage: Light-emitting diodes use a low-voltage power supply, the power supply voltage is between 2-4V, depending on the product, so it is driven by a higher voltage power supply; a safer power supply, especially suitable for Public places. Current: The working current is 0-15mA, and the brightness becomes brighter as the current increases.
2. Efficiency: The energy consumption is reduced by 80% compared with incandescent lamps with the same light effect. Applicability: 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.
3. Response time: The response time of the incandescent lamp is milliseconds, and the response time of the light-emitting diode lamp is nanoseconds. Environmental pollution: no harmful metal mercury.
4. 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 light-emitting diode at low current can turn into orange, yellow, and finally green as the current increases. What is the price of a light-emitting diode? After reading the above content, everyone knows how to buy it. Generally, the price is calculated based on its power, which usually ranges from a few yuan to a few hundred yuan, so it depends on yourself Needs to buy. What are the characteristics of light-emitting diodes, such as its applicability, color, efficiency, etc., have different utilization values. After everyone understands these, they will have some help when choosing light-emitting diodes.
