ထုတ်ကုန်အပေါ် ဦး ဆောင်သောအားဖြင့်ထုတ်လုပ်သောအပူ၏သက်ရောက်မှု

ထုတ်ကုန်အပေါ် ဦး ဆောင်သောအားဖြင့်ထုတ်လုပ်သောအပူ၏သက်ရောက်မှု

1: Luminous efficiency – As temperature rises, luminous efficiency decreases.

2: Wavelength – As temperature rises, wavelength drifts to longer wavelengths (red shift).

3: Correlated color temperature (cct) – As temperature rises, the correlated color temperature of white light increases, and the correlated color temperature of other colors decreases.

4: Forward voltage – As temperature rises, forward voltage decreases.

5: Reverse current – As temperature rises, reverse current increases.

6: Thermal stress – As temperature rises, thermal stress increases.

7: Device life – As temperature rises, device life shortens.

8: If the LED package contains phosphors, epoxy resins, etc., the temperature rise will also cause the degradation of these materials.
