| A common type of LED, from the P-N junction area to the ambient temperature the total thermal resistance of 300 to 600 ℃ / w between the well-structured for a power-type LED components, the total thermal resistance of about 15 to 30 ℃ / w. A huge difference in thermal resistance, shows that common type of LED components, only a very small input power conditions, in order to work properly, while the power dissipation of power-type components can be as large as watts or even higher. |
