In this study, we designed and fabricated the LED navigation lighting system which complements the disadvantages of conventional light and improves luminous performance. A 5.6 W LED module was fabricated to replace a 60 W incandescent lamp, and its diameter was minimized to dispose itself on the focal point of conventional lens. To improve heat radiation, holes were made on the heat sink, resulting in increasing the surface area, and the loss of luminous intensity was decreased applying a structure which consists of a clear lens and color LED. Optical characteristics of the prototype were measured, and the results satisfied the COLREG and the EN 14744 showing 70% of maximum vertical luminous intensity in range of ${pm}5^{circ}$, and horizontal luminous intensity was 184.7 cd, increased by 20% compared to incandescent lamp. In conclusion, the fabricated LED navigation lighting system showed improved electrical and optical performances with power consumption reduced by more than 90% and luminous intensity increased by 20%.
