With the advancement of science and technology and the increasing awareness of environmental protection, 주도의 lighting technology has been widely used in many fields, such as home, commercial, industrial, and outdoor lighting, due to its advantages of high efficiency, energy saving, and environmental protection.
As the core component of LED lighting products, LED lamp beads’ performance and lifespan are directly related to the lighting effect and product economy. Therefore, how to effectively protect the life of LED lamp beads has become an important issue that we cannot ignore.
1. Working principle of LED lamp beads and factors affecting lifespan
1). Basic working principle of LED lamp beads
LED (Light Emitting Diode) lamp bead is a solid-state semiconductor device that can directly convert electrical energy into light energy. The core structure of LED lamp beads includes a P-type semiconductor (positive electrode) and an N-type semiconductor (negative electrode), as well as an active layer between them.
When current passes through the LED, electrons flow from the N-type semiconductor to the P-type semiconductor, combine with holes, and release energy. This energy is emitted in the form of photons, which is the visible light we see.
The working principle of LED lamp beads is based on the electroluminescence effect. The light-emitting process does not require thermal excitation, so it has the advantages of high efficiency, energy saving, and environmental protection.
2). Main factors affecting the life of LED lamp beads
The life of LED lamp beads is affected by many factors. The following are the main aspects:
- 온도
Temperature is one of the key factors affecting the life of LED lamp beads. LED lamp beads will generate a certain amount of heat when working. If the heat dissipation is poor and the temperature is too high, it will accelerate the aging of the internal materials of the LED lamp beads, thus reducing its luminous efficiency and lifespan.
Therefore, when designing and using LED lamps, heat dissipation issues must be fully considered, and effective heat dissipation measures must be taken, such as using heat sinks, fans, etc., to ensure that the LED lamp beads work within a suitable temperature range.
