Abstract

A high intensity LED based lighting array for use in an obstruction light with efficient uniform light output is disclosed. The high intensity LED based lighting array has a first concentric ring having a plurality of reflectors and light emitting diodes. The concentric ring has a planar surface mounting each of the plurality of reflectors in perpendicular relation to a respective one of the plurality of light emitting diodes. At least some of the first plurality of reflectors are adjustable relative to the position of the respective light emitting diode to produce a precise beam pattern from the light emitting diode.

Claims (27)

1. A light engine for a high intensity light comprising:

a first ring having a first plurality of reflectors and light emitting diodes, the first ring having a planar surface mounting each of the plurality of reflectors in positional relation to a respective one of the plurality of light emitting diodes, some of the plurality of reflectors being individually adjustable relative to the position of the respective light emitting diode to produce a precise beam pattern from the light emitting diode.

2. The light engine of claim 1 , wherein at least one of the reflectors has a reflective side having an exterior reflective surface, an interior reflective surface and an inset reflective surface disposed on the interior reflective surface.

3. The light engine of claim 1 , wherein the first ring has a circular beam blocker to prevent stray light from being emitted below a predetermined angle of elevation.

4. The light engine of claim 1 , further comprising a second, third, and fourth ring, each ring having a plurality of reflectors and light emitting diodes, the second, third, and fourth rings mounted on the first ring.

5. The light engine of claim 4 , further comprising a fifth ring having a plurality of reflectors and light emitting diodes, wherein the light emitting diodes of the first through fourth rings are white light emitting diodes and the light emitting diodes of the fifth ring are red light emitting diodes.

6. The light engine of claim 1 , wherein the high intensity light is compliance with FAA and ICAO standards.

7. The light engine of claim 1 , wherein the first ring includes a plurality of circuit boards mounting the light emitting diodes and a heat sink coupled to the plurality of circuit boards.

8. The light engine of claim 1 , wherein the reflectors each include a mounting post that may be mated with a mounting surface to allow the transverse and rotational adjustment of the reflector relative to the LED.

9. The light engine of claim 1 , wherein the reflectors each form a horizontal beam approximately 5 to 10 degrees wide.

10. The light engine of claim 4 , where the rings are offset from each other to reduce azimuth ripple.

11. The light engine of claim 4 , wherein the second ring is adjustable relative to the first concentric ring to create a different offset angle.

12. A high intensity light beacon compliant with FAA and ICAO standards, the light beacon comprising:

a first ring having a first plurality of reflectors and light emitting diodes, the first ring having a planar surface mounting each of the plurality of reflectors in positional relation to a respective one of the plurality of light emitting diodes, each of the plurality of reflectors being individually adjustable relative to the position of the respective light emitting diode to produce a precise beam pattern from the light emitting diode;

a second ring mounted on the first ring, the second ring having a second plurality of reflectors and light emitting diodes, the second ring having a planar surface mounting each of the plurality of reflectors in perpendicular relation to a respective one of the plurality of light emitting diodes, the second ring being rotationally offset from the first ring such that the second plurality of reflectors and light emitting diodes are staggered by a radial angle from the reflectors and light emitting diodes of the first ring;

a third ring mounted on the second ring, the third ring having a third plurality of reflectors and light emitting diodes, the third ring having a planar surface mounting each of the plurality of reflectors in perpendicular relation to a respective one of the plurality of light emitting diodes, the third plurality of reflectors and light emitting diodes being staggered by a radial angle from the reflectors and light emitting diodes of the second ring; and

a fourth ring mounted on the third ring, the fourth ring having a fourth plurality of reflectors and light emitting diodes, the fourth ring having a planar surface mounting each of the plurality of reflectors in perpendicular relation to a respective one of the plurality of light emitting diodes, the fourth plurality of reflectors and light emitting diodes being staggered by a radial angle from the reflectors and light emitting diodes of the third ring.

13. The light beacon of claim 12 , wherein at least one of the reflectors has a reflective side having an exterior reflective surface, an interior reflective surface and an inset reflective surface disposed on the interior reflective surface.

14. The light beacon of claim 12 , wherein the first, second, third and fourth rings have a circular beam blocker to prevent stray light from being emitted below a predetermined angle of elevation.

15. The light beacon of claim 12 , wherein the reflectors each include a mounting post that may be mated with a mounting surface to allow the transverse and rotational adjustment of the reflectors relative to the LEDs.

16. The light beacon of claim 12 , wherein the first plurality of LEDs is thirty-six LEDs and second plurality of LEDs is thirty-six LEDs.

17. The light beacon of claim 12 , wherein the reflectors each form a horizontal beam approximately 5 to 10 degrees wide.

18. The light beacon of claim 12 , where the offset between rings is used to reduce azimuth ripple.

19. The light beacon of claim 12 , wherein the second ring is adjustable relative to the first ring to create a different offset angle.

20. An optical element for use in a light, the optical element comprising:

a light emitting diode fixed on a mounting surface; and

a reflector having a reflective surface, the reflective surface shaped to emit a specific beam pattern from light reflected from the light emitting diode, the reflector including a positioning member resting on the mounting surface, the positioning member allowing the reflector to be adjusted between angular positions relative to the light emitting diode on the mounting surface.
