- •
Thermal modeling and temperature measuring are applied to predict the Tj of LED lamps.
- •
The lumen maintenance of LED lamps is further estimated with the predicted Tj.
- •
The thermal resistance model of LED lamps is simplified into a one-dimensional model.
- •
The estimation method is efficient to predict the luminous maintenance of LED lamps.
- •
The proposed method is expected to be useful for the fast qualification of LED lamps.
