Investigation of temperature regime and luminous flux of light-emitting element of light emitting diode lamp

Статья в журнале

The article presents the results of computer simulation of heating regime, experimental investigation of temperature pattern and luminous flux of the stripe-patterned light-emitting element of LED lamp with convection gas cooling. Computer simulation of heating regime was carried out with the help of CFD software using the finite element method (FEM); luminous intensity distribution curve was simulated by means of optics simulation program. The experiments were performed using a thermal imaging camera and goniophotometer. The light emitting element is a thin sapphire substrate having a chip-on-board (COB) LED array disposed thereon. Studies have shown that temperature increases linearly with the forward current increase, reaching 155°C at the rated operating conditions. Luminous flux ceases to increase significantly at a current of 22.5 mA. The article has discussed the results and proposed possible options for optimizing the heating regime of the light emitting element.
