Abstract
A rotational obstruction and beacon signaling apparatus, in which chip-on-board (COB) packaged light emitting diodes (LEDs) are employed to provide a flashed emission pattern with high luminous intensity. The flash sequence of individual LEDs is controlled by an electronic timing circuit to simulate a rotational or other motional signaling effect.
Claims15
An obstruction and beacon signaling apparatus, comprising:
- a plurality of high intensity chip-on-board (COB) packaged light emitting diode (LED) units, being mounted on the circumference of a heat sink to produce a plurality of light beams, wherein heat produced by said plurality of LED units is dissipated through said heat sink;
- a plurality of optical beam transformers, each transformer being positioned in a path of a beam among said plurality of light beams, for individually controlling a set of properties of each beam and producing a transformed light beam with high luminous intensity;
- and
- an electronic timing circuit for modulating a drive current of said plurality of LED units, such that the luminous intensity of said transformed light beams are modulated to produce a time sequenced flash pattern for long-distance obstruction and beacon signaling;
- wherein each optical beam transformer among the plurality of optical beam transformers is associated with a respective LED unit among the plurality of high intensity LED units to individually control the set of properties of one associated light beam;
- wherein the optical beam transformer comprises a non-imaging optical lens and an optical diffuser;
- wherein the plurality of high intensity chip-on-board (COB) packaged light emitting diode (LED) units is mounted on a plurality of vertically adjacent stacks thereby producing an improved luminous intensity for the signaling apparatus.
