| Abstract |
In this paper, luminaire optical efficiency and luminous intensity according to array of HB(high brightness) white LED(light emitting diode) and globe types of luminaire were simulated by computer and made a comparative analysis. LEDs were arranged by square of 7ea X 7ea. LED space has been divided into 8.2㎜, 10㎜ and 15㎜ that mean distances between luminous centers of LEDs, and luminaire globes were classified into 30mm and 50mm away from luminous center of LEDs. Also the simulations were made with / without globe, globe types were specified by convex and embossing types of which sizes are 8.2mm and 5.0mm. So total 27 classes of simulation were performed. This paper is to help luminaire development using LED light source called digital lighting of 21th century, by studying luminaire efficiency and luminous intensity of different types of globes. |
