Abstract:
An aircraft forward position light source comprising:a base structure; multiple LED components mounted on the base structure, and adapted so that, when powered, the LED components emit light that meets the candela output design criteria defined in Table 1 and Table 2 and the Federal Aviation chromaticity requirements for the light source; wherein Table 1 is: TABLE 1Candela Output Design Criteria in the Horizontal PlaneDihedral AngleMinimum Candela (cd)â€‚0 to 10 degrees40 cd10 to 20 degrees30 cd10 to 110 degreesâ€‚5 cdwherein Table 2 is: TABLE 2Candela Output Design Criteria in the Vertical PlaneAngle Above and Below theHorizontal PlaneMinimum Candela (cd)0degrees40 cd1 to 5degrees36 cd6 to 10degrees32 cd11 to 15degrees28 cd16 to 20degrees20 cd21 to 30degrees12 cd31 to 40degreesâ€‚4 cd41 to 90degreesâ€‚2 cdand, wherein the multiple LED components are comprised of multiple sets of LED components including a first set of LED components at a first defined angle distally relative to normal, a second set of LED components at a oriented substantially normal, a third set of LED components at a third defined angle downwardly relative to normal, and a fourth set of LED components at a fourth defined angle upwardly relative to normal.
