Here, it will be very favourable introducing the ask for something of the forward position indicator lamp being executed by Federal Aviation Regulation (FAR).Should be known in that following explanation just is used for illustration purpose, rather than exhaustive as standard that the forward position indicator lamp is executed or requirement.
Each forward position indicator lamp must be shown as continuous light in the angular range separately in horizontal surface (this horizontal surface comprises the longitudinal axis of aircraft, and perpendicular to the diad of aircraft).
For example, must be shown as when the time at the forward position indicator lamp (redness) on the wing of left side and in the scope of the left side of this longitudinal axis from 0 to 110 degree, be continuous light along the longitudinal axis eyes front of aircraft.This angular range corresponding to this redness forward position indicator lamp is called dihedral angle L.
On the contrary, must be shown as when the time at the forward position indicator lamp (green) on the wing of right side and in the scope of the right side of this longitudinal axis from 0 to 110 degree, be continuous light along the longitudinal axis eyes front of aircraft.This angular range corresponding to this green forward position indicator lamp is called dihedral angle R.
(dihedral angle A is the angular range corresponding to the rear positions indicator lamp, and span is that 70 degree to 70 of this longitudinal axis left side from this longitudinal axis right side is spent when axis eyes front longitudinally.)
As previously mentioned, FAR represented for aircraft each forward position indicator lamp (red and green), as the specific minimum and the maximum light intensity of the function of emission angle.In horizontal surface, FAR stipulated for red forward position indicator lamp in dihedral angle L minimum light intensity and for the minimum light intensity of green forward position indicator lamp in dihedral angle R.Table 1 has been represented the particular example for these minimum light intensity of horizontal surface, and is as the Part 23 of FAR, listed among the Sec.23.1391.

| The 10-20 |
30 |
| The 20-110 degree | 5 |
FAR has also stipulated the minimum light intensity of forward position indicator lamp in any vertical plane surface, the function of its minimum light intensity as horizontal surface (1) and the angle above or below this horizontal surface.Table 2 has been represented these minimum light intensity (according to 1) (according to Part 23, Sec.23.1393 is as the application's archive data) in these regulations
Table 2
| On horizontal surface or below angle | Intensity |
| 0 degree | 1.00×1 |
| The 0-5 degree | 0.90×1 |
| The 5-10 degree | 0.80×1 |
| The 10-15 degree | 0.70×1 |
| The 15-20 degree | 0.50×1 |
| The 20-30 degree | 0.30×1 |
| The 30-40 degree | 0.10×1 |
| The 40-90 degree | 0.05×1 |
In order to prevent the excessive overlapping between the position indicator forwardly, FAR has also stipulated in horizontal surface the maximum light intensity as the function of emission angle.Particularly, FAR has determined the maximum light intensity that red forward position indicator lamp can have in the specific region of adjacent dihedral angle R.Also stipulated the maximum light intensity of green forward position indicator lamp in the specific region of the adjacent dihedral angle L of horizontal surface.And FAR has stipulated the maximum light intensity of red and green forward position indicator lamp in the specific region of adjacent dihedral angle A (so that prevent with the rear positions indicator lamp excessive overlapping).Table 3 has been represented the particular instance of these maximum light intensity, as the Sec.1395 of FAR, described in the Part23.
Maximum light intensity (bougie decimale)

| Overlap | Zone A | Area B |
| Green in |
10 | 1 |
| Red in |
10 | 1 |
| Green in dihedral angle A | 5 | 1 |
| Red in dihedral angle A | 5 | 1 |
As defined among the FAR, regional A be included in through light source and with the adjacent dihedral angle of public boundary level crossing (surpass 10 degree but less than 20 degree) in all directions.Area B be included in through light source and with the adjacent dihedral angle of public boundary level crossing (surpass 20 degree) in all directions.
Therefore, the regulation shown in the table 3 has been determined to block for the angle of each forward position indicator lamp.Surpass these angles and block, must be restricted to or be lower than the maximum light intensity of regulation in the table 3 by the light intensity of each forward position indicator lamp emission.
Like this, FAR has stipulated to enter among adjacent dihedral angle R and the A 10 angles when spending and block surpassing dihedral angle L for red forward position indicator lamp, and at this moment limitation in light intensity is 10 bougie decimales or lower.Also stipulated to enter among adjacent dihedral angle R and the A 20 another angles when spending and block surpassing dihedral angle L for red forward position indicator lamp, at this moment limitation in light intensity is 1 bougie decimale or lower.
Should be known in that parameter in the table 3 represented the requirement among the Part 23 of FAR, it belongs to normally, practical, stunt and airplane in commuter category.The other parts that but should be known in FAR have also been stipulated the minimum and maximum light intensity requirement for other type airplane.For example, Part 25 provides the FAR requirement for airplane in transportation category, and Part 27 provides the requirement for normal class autogiro, and Part 29 provides the requirement for transportation class autogiro.
Should be known in that FAR also comprises other requirement in these parts, comprise the specific wavelength (being color) of each lamp.

Fig. 3 A has represented the cutaway view of the installed module 20 of this embodiment.Particularly, Fig. 3 A has represented the example constructions of parasite 220, wherein, for each sidepiece emission LED 210 single parasite 220 is arranged all.As shown in Figure 3A, the reflecting surface of each parasite 220 can be crooked.The shape of each parasite 220 is defined as making parasite 220 to come reflected light according to above-mentioned required pattern.
In optional example embodiment, single parasite 220 can be used to produce the reflected light of required pattern.For example, single parasite 220 can be designed to " bimodal " shape, and wherein, the shape at each peak is configured to reflect the light of corresponding one of them sidepiece emission LED 210.
According to example embodiment, the structure of this customization parasite 220 is to come design-calculated according to the orientation of sidepiece emission LED210, thereby makes this reflected light form specific pattern.This pattern can be launched the emission light combination of LED 210 with sidepiece, distribute so that form first of light, i.e. the emission of first led module distributes.
According to orientation and the luminescence feature of LED 230, the light of being launched by lambertian LED 230 forms second distribution.This of light second distributes corresponding to the light that is produced by second led module.The technology of determining the appropriate orientation of lambertian LED 230 according to the luminescence feature of LED 230 is that those of ordinary skills are known, and does not need to carry out undo experimentation.
Like this, first and second light that distribute are combined to form from the light pattern of forward position indicating lamp device 1 emission.According to example embodiment, first and second led modules (comprising sidepiece emission LED210, parasite 220 and lambertian LED 230) are arranged so that formed light pattern satisfies the requirement of FAR to minimum light intensity.As mentioned above, those of ordinary skills readily appreciate that how sidepiece emission LED 210 and parasite 220 and lambertian LED230 are set, make the light pattern of this forward position indicating lamp device satisfy the minimum strength requirement of FAR.
According to example embodiment, sidepiece emission LED 210 and lambertian LED 230 are arranged to FAR the color that the requirement of the forward position indicating lamp device 1 of specific position conforms to is launched light.In this embodiment, when this forward position indicating lamp device 1 will be installed on the right side wing of aircraft, each LED 210 and 230 can be arranged to launch the green light (" aviation is green ") that satisfies FAR.On the other hand, when this forward position indicating lamp device 1 will be installed on the left side wing of aircraft, LED 210 and 230 can be arranged to launch the red light (" aviation is red ") that satisfies FAR.Being arranged to launch aviation sidepiece emission LED and lambertian the LED red and light that aviation is green can be easy to buy from the market.
Therefore, in above-mentioned example embodiment, the light that this forward position indicating lamp device 1 does not need to use stained glass that special color is provided is to satisfy the regulation of FAR.
Should be known in that aviation is red and aviation is green sidepiece emission LED210 has different luminescence features, therefore make they separately be distributed with some difference.Therefore, in order to obtain the optimal light pattern, be configured to launch aviation ruddiness or aviation green glow according to this forward position indicator lamp 1, the structure of parasite 220 can be slightly different.
