| Abstract: | In this paper, the optical-thermal characteristics for single-power light-emitting diodes (LEDs) are firstly studied based on experiment and theory, with both results in good agreement. Based on the results of single-power LED, an optical system is proposed with thermal-optical LED array modules, which are assembled upon a spherical base plate with heat sink. By simulation, the optical system is proved to provide uniform illumination. The luminance uniformity of the illuminated target is up to 0.9. The thermal effects under different heat convection coefficient and power consumption on the LED array modules are discussed in detail. Based on the heat transfer characteristics for the LED system, the approximate allowable power consumption for modules can be found. [ABSTRACT FROM PUBLISHER] |
