Inline light emitting diodes, also known as plug-in light emitting diodes, are energy-saving and environmentally friendly visible lighting materials. They are solid-state semiconductor devices that can convert electrical energy into visible light. The light-emitting principle of LEDs is to make electric current flow through compound semiconductors, and through the combination of electrons and holes, release excess energy in the form of light, thereby achieving a light-emitting effect. The wavelength of the light emitting diode used for visible light is 400-700 nm.
Generally, users who purchase LED lamps and lanterns will consider the service life of the lamps and lanterns. What are the factors that maintain the long life of LED lamps and lanterns? The manufacturers of in-line LED lamp beads have summarized the following tips for extending the life of in-line LED lamp beads:
1. Power supply: LED lamp power supply is a very important part of LED lamps. Generally, there are two schemes for power supply: isolated and non isolated. The isolation volume is large and the efficiency is low, and it is mostly used for low-cost products. Non isolated drives are used in products with small size, high efficiency, low heat dissipation, high stability, and high added value.
2. Light source: LED lamps with the same brightness use different light sources (LED beads or LED patches). Even with the same light source, the quality and price of different in-line LED lamp bead manufacturers are different. Large brand LED lamp products are basically made with good light sources.
3. Heat dissipation: The LED light source is attached to an aluminum substrate with good thermal conductivity. The heat dissipation of the in-line LED lamp beads and the heat dissipation of the power supply are separate and do not interfere with each other, ensuring the rationality of heat dissipation. Generally, aluminum materials with high thermal conductivity and good heat dissipation are used. If the quality is poor, a heat dissipation method with poor thermal conductivity is used, and even LED lamp beads and power supplies share heat dissipation, resulting in poor heat dissipation and easy damage.
