Embodiment Construction

[0049] figure 1 Shown is a lighting device 10 according to an exemplary embodiment of the present invention, which includes a main body 11 and lamp units 12 , 13 . attached figure 1 The medium lighting device 10 is shown as an elevated runway edge light.

[0050] The main body 11 is removably attached to the support 14 by a quick release coupling 16 . Thus, the main body 11 can be quickly and easily attached to and removed from the support 14 without requiring any tools. The supporting member 14 may be a bracket protruding from the ground plane and fixed to the ground 15 . Therefore, the support 14 enables the lighting device 10 to be installed at a higher position above the ground level. Depending on the fragility requirements of the overhead light, the support 14 preferably includes weak points (not shown).

[0051] The body 11 encloses electronic circuitry 19 for powering and driving the one or more LEDs. The body is also capable of encapsulating additional circuitry ...

Abstract

Elevated airfield lighting device (10), comprising a main body (11) securable to a support (14) enabling the main body (11) to be fixed at an elevated position from ground (15), and at least one light unit (12, 13) comprising at least one LED (17), wherein the main body (11) encloses an electronic circuit for powering and driving the LED and comprises a first heat sink (110) thermally coupled to the electronic circuit and wherein the light unit comprises a second heat sink (120, 130) for dissipating heat generated by the LED. The lighting device (10) is characterised in that the light unit (12, 13) is formed as a separate body from the main body (11) and comprises a front (12, 132) for transmitting light emitted from the LED and a back comprising a rear surface at which the second heat sink is provided. The light unit is removably attachable to the main body, wherein when attached, the rear surface (120, 130) is interposed between the front and the main body and a fluid passage is formed between the main body (11) and the light unit (12, 13) where ambient air can pass so that the second heat sink can dissipate heat to the ambient air by natural convection.

Description

technical field [0001] The present invention relates to LED light source based overhead lights for airports. In particular, the present invention relates to high intensity airport lights, such as airport runway edge lights, end lights, runway threshold lights, and approach lights. Background technique [0002] LED light sources are gradually used in airport lights. The advantages of LEDs over incandescent or halogen light sources are well known. Those skilled in the art also know that despite the high energy efficiency of LEDs, a large amount of heat is generated in the LEDs and their power supply and control systems. Ensuring the long lifetime of LED light sources requires keeping the light emitting junction of the LED below a critical value, which is much lower than that of an incandescent lamp (400°K vs. 3000°K). Therefore, the heat generated must be efficiently removed. [0003] In US 2008 / 002410 an omnidirectional marker light utilizing LEDs is disclosed comprising ...
