LED에서 발생하는 열이 제품에 미치는 영향

LED에서 발생하는 열이 제품에 미치는 영향

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: 순방향 전압 – 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, 등., the temperature rise will also cause the degradation of these materials.
