Airfield lighting apparatus

摘要

Lighting apparatus for airports, in particular flush light, having housing with a housing base and a housing top that includes a recess for receiving a light disc. Light disc facilitates the emission of light from a light source, disposed in the interior of the housing, to the surroundings. A light source carrier on which the light source is mounted is attached to a heat transfer block locked in a recess of the housing top such that edges and/or at least partially flat sides of the heat transfer block are in direct contact with the corresponding sides of the recess.

主权项

1. A lighting apparatus for airports comprising:
a housing having a bottom housing part and a housing top,
wherein the housing top comprises a first recess sized to fit around a lens affixed therein with a seal,wherein said lens is structured to transmit light to the ambient environment from a light source arranged in an interior space of the housing, a light source carrier on which the light source is mounted,
wherein the light source carrier is fixed to an upper surface of a heat-conducting block, said upper surface being oblique with respect to a lower surface of the heat-conducting block,wherein said heat-conducting block is secured in a second recess formed in a bottom surface of the housing top such that said upper surface faces said bottom surface,wherein at least one of the peripheral sides and at least partly flat sides of the heat-conducting block rest directly on corresponding sides of the second recess, andwherein the heat-conducting block is detachably fixed to the housing top, and reflectors optically connecting the light source with said ambient environment through said lens,
each of said reflectors structured to change both a direction of propagation and a curvature of a wavefront of light upon propagating of said light from the light source to the lens,each of said reflectors disposed at at least partly flat side of the heat conducting block.
