|---|---|
| 1,000 | 0 |
| 3,000 | <1% |
| 10,000 | <3% |
| 50,000 | <30% |
Most LED chips lose less than 3% brightness each year. After 50,000 hours, the light may still be 70-80% as bright as when it was new.
Heat Dissipation Importance
Heat can damage LED chips and shorten their life. Good heat dissipation helps the LED chip stay cool and last longer. If the chip gets too hot, it will not work as well. For every 10°C rise in temperature, the lifespan drops by about half. You can see why heat management matters in the table below:
| Key Point | Description |
|---|---|
| Thermal Degradation | Excessive heat can lead to thermal degradation, reducing light output and lifespan of LEDs. |
| Importance of Heat Dissipation | Effective heat dissipation mechanisms are essential to maintain optimal operating temperatures. |
