Knowledge of Performance Characteristics of LED Light Emitting Diodes and LED Beads
withLamp bead productsapplicationMore and more widespread, LED light emitting diodes, LED bead electronic componentsThe product of the itemSelection,According to different industry applications, there are also differences in product functions and usesThey are becoming increasingly segmented, covering LED beads in series, surface mount, high-power, COB, and infrared light-emitting diodes.For optoelectronic devicesVoltage for product applicationDo you know the basic characteristics of LED chips and LED light-emitting diodes, such as current and power requirements? Below, we will take you to understand these issues together.
The basic performance characteristics and application knowledge of LED light emitting diodes and LED beads include the following aspects:
1. LED beads have a small volume. LED chips are basically small chips encapsulated in epoxy resin, so they are very small and lightweight.
2. The LED bead voltage is low. LED beads use a low-voltage power supply with a supply voltage between 2-4V, which varies depending on the product, so it is driven by a higher voltage power supply than the high-voltage power supply; Safer power supply, especially suitable for public places.
3. Long service life. Under appropriate current and voltage, the lifespan of LED can reach 100000 hours.
4. LED bead efficiency. Energy consumption is reduced by 80% compared to incandescent lamps with the same luminous efficiency.
5. Response time. The response time of its incandescent lamp is in the millisecond range, while the response time of its LED lamp is in the nanosecond range.
6. LED beads have high brightness and low heat. LED uses cold light technology, which generates much lower heat than ordinary lighting fixtures of the same power.
7. LED optoelectronic devices are environmentally friendly. LEDs are made of non-toxic materials, unlike fluorescent lamps that contain mercury and can cause pollution. At the same time, LEDs can also be recycled and reused.
