Abstract
An LED array warning light system comprises a plurality of struts in a generally conical configuration. Each strut has an upper and lower edge and an inner and an outer edge. A plurality of light emitting diodes are affixed one above the other to an edge of each strut. A top disk with radial slots receives and is affixed to an upper edge of an associated strut. A bottom disk has radial slots which receive and are affixed to a lower edge of an associated strut. The disks are sized whereby the LED's are at an angle of between 3 and 25 from the axis.
Claims9
An LED array warning light system for rendering towers, cables and tall buildings visible to approaching aircraft, comprising, in combination:
- fifteen elongated plate-like struts vertically aligned in a generally conical configuration, each strut having a short horizontal upper edge and a parallel short horizontal lower edge and with a long inner edge and a parallel long outer edge;
- six light emitting diodes arrays, each LED with an external light emitting portion and an internal non-light emitting portion, each affixed one above the other to the outer edge of each strut;
- a horizontal small too disk having a centrally disposed vertical axis, the top disk having fifteen radial slots, each slot receiving and affixed to an upper edge of an associated strut;
- a horizontal large bottom disk having a centrally disposed vertical axis, the bottom disk having fifteen radial slots, each slot receiving and affixed to a lower edge of an associated strut, the axes of said top and bottom disk being a common vertical axis, the disk's being sized whereby the LED's are at an angle of between 3 and 25 degrees, preferably 10 degrees, from the common vertical axis;
- an array base having a lower face and an upper circular face receiving and supporting the bottom disk and struts, top disk and LED's;
- the struts, disks and LED's constituting a light source array;
- a threaded attachment depending on a downwardly from the lower face of the array base;
- the disks and struts being fabricated from electrically insulating material with a thermally insulating layer and with electrically conductive lines for conducting power to the LED's;
- a base with a threaded internal socket having electrically conductive portions for receiving the threaded attachment and the passage of electrical energy from a remote power source to the LED's;
- and
- a translucent dome supported by the base with an open too for the dissipation of heat and with a lenticular array to provide azimuthal spread.
An LED array warning light system comprising:
- a plurality of struts in a generally conical configuration, each strut having an upper and lower edge and with a inner and an outer edge;
- a plurality of light emitting diodes affixed one above the other to an edge of each strut whereby the light emitting diodes may be viewed for 360 degrees;
- a top disk with radial slots for receiving and affixed to an upper edge of an associated strut;
- and
- a bottom disk with radial slots for receiving and affixed to a lower edge of an associated strut, the disks being sized whereby the LED's are at an angle of between 3 and 25 degrees from the axis.
