Abstract

An airfield light, components thereof, and associated methods. The airfield light can include a baffle including a baffle body and one or more baffle members secured to the baffle body. The baffle members are configured to cover portions of a baffle window. At least one light source is mounted in association with the baffle and emits light out of the baffle window. The baffle members cover portions of the baffle window for blocking light transmission therethrough. A method of assembling an airfield light includes arranging a baffle to shroud a light assembly and removing a baffle member to permit light from the light assembly to emit through a portion of a baffle window opened by removing the baffle member. A baffle for an airfield light is also disclosed.

First claim

What is claimed is:

1. An airfield light comprising:
a support;
a first light source connected to the support;
a baffle proximate the first light source, the baffle including
a generally opaque baffle body defining a window having a first open portion through which light emitted from the first light source may pass, and
a generally opaque baffle member secured to the baffle body and blocking a closed portion of window to inhibit light emitted from the first light source from passing therethrough, wherein the generally opaque baffle member is removable from the baffle body to create a second open portion of the window; and

a generally light-transmissible cover surrounding the first light source and the baffle such that the light emitted by the first light source through the first open portion of the window passes through the cover,
wherein the baffle is sized and shaped to be in a close fitting relationship with a portion of the cover,
wherein the baffle is sized and shaped to fill a front portion of the cover to inhibit light emitted by the first light source from entering a back portion of the cover.

2. An airfield light as set forth in claim 1 , wherein the baffle further includes a second generally opaque baffle member secured to the baffle body and blocking a second closed portion of window to inhibit light emitted from the first light source from passing therethrough, wherein the second generally opaque baffle member is removable from the baffle body to create a third open portion of the window.

3. An airfield light as set forth in claim 1 , wherein the baffle further includes a generally opaque partition positioned above the first light source to block light emitted from the first light source.

4. An airfield light as set forth in claim 3 , wherein the partition is secured to the baffle member adjacent the first open portion of the window and is removable from the baffle member.

5. An airfield light as set forth in claim 1 , wherein the support is a first support and the baffle is a first baffle, the airfield light further comprising:
a second support;
a second light source connected to the second support; and
a second baffle proximate the second light source, the second baffle including
a generally opaque baffle body defining a window having a first open portion through which light emitted from the second light source may pass, and
a generally opaque baffle member secured to the baffle body and blocking a closed portion of window to inhibit light emitted from the second light source from passing therethrough, wherein the generally opaque baffle member is removable from the baffle body to create a second open portion of the window.

6. An airfield light as set forth in claim 5 , wherein the light emitted from the first light source is directed in a first direction, the light emitted from the second light source is directed in a second direction, the first and second directions being generally opposite of one another.

7. An airfield light as set forth in claim 6 , wherein the first baffle inhibits light emitted by the first light source from traveling in the second direction, wherein the second baffle inhibits light emitted by the second light source from traveling in the first direction.

8. An airfield light as set forth in claim 5 , wherein a first baffle color of the first baffle and a first light color of the light emitted by the first light source are generally the same, wherein a second baffle color of the second baffle and a second light color of the light emitted by the second light source are generally the same, wherein the first baffle color and first light color are different than the second baffle color and second light color.

9. A method of assembling an airfield light, the method comprising:
mounting first and second light assemblies on a support;
removing at least a first generally opaque baffle member from a baffle body of a baffle;
arranging the baffle to shroud the first and second light assemblies, the first and second light assemblies configured to emit light through a window defined by the baffle, the second light assembly configured to emit light through a portion of the window opened by removing the first generally opaque baffle member from the baffle body; and
mounting a third light assembly on the support and removing a second generally opaque baffle member from the baffle body, the third light assembly being configured to emit light through a portion of the window opened by removing the second generally opaque baffle member.

10. A method as set forth in claim 9 , further comprising:
mounting third and fourth light assemblies on a second support;
removing at least a first generally opaque baffle member from a baffle body of a second baffle;
arranging the second baffle to shroud the third and fourth light assemblies, the third and fourth light assemblies configured to emit light through a window defined by the second baffle, the fourth light assembly configured to emit light through a portion of the window opened by removing the first generally opaque baffle member from the baffle body of the second baffle;
arranging the second support and second baffle with respect to the support and the baffle such that the light emitted from the first light source is emitted in a first direction, the light emitted from the second light source is emitted in a second direction, the first and second directions being generally opposite of one another.

11. An airfield light comprising:
a first support;
a first light source connected to the support; and
a first baffle proximate the first light source, the first baffle including
a generally opaque baffle body defining a window having a first open portion through which light emitted from the first light source may pass, and
a generally opaque baffle member secured to the baffle body and blocking a closed portion of window to inhibit light emitted from the first light source from passing therethrough, wherein the generally opaque baffle member is removable from the baffle body to create a second open portion of the window;

a second support;
a second light source connected to the second support; and
a second baffle proximate the second light source, the second baffle including
a generally opaque baffle body defining a window having a first open portion through which light emitted from the second light source may pass, and
a generally opaque baffle member secured to the baffle body and blocking a closed portion of window to inhibit light emitted from the second light source from passing therethrough, wherein the generally opaque baffle member is removable from the baffle body to create a second open portion of the window,

wherein the light emitted from the first light source is directed in a first direction, the light emitted from the second light source is directed in a second direction, the first and second directions being generally opposite of one another.

12. An airfield light as set forth in claim 11 , wherein the baffle further includes a second generally opaque baffle member secured to the baffle body and blocking a second closed portion of window to inhibit light emitted from the first light source from passing therethrough, wherein the second generally opaque baffle member is removable from the baffle body to create a third open portion of the window.

13. An airfield light as set forth in claim 11 , wherein the baffle further includes a generally opaque partition positioned above the first light source to block light emitted from the first light source.

14. An airfield light as set forth in claim 13 , wherein the partition is secured
