Bidirectionally luminous runway edge lamp

Abstract

The invention relates to a bidirectionally luminous runway edge lamp, which comprises a lamp shade and a lamp holder. A radiating lamp bracket for fixing a light source is arranged inside the lamp shade, and is connected with the lamp holder; the lamp also comprises at least one yellow light-emitting diode (LED) light source which is fixed on the radiating lamp bracket, and a corresponding white LED light source; an inclined angle of 2 to 5 degrees is formed between emergent rays of the white LED light source and the yellow LED light source and the same plane; an inclined angle between the two emergent rays is more than 90 degrees and less than 180 degrees; a first Fresnel lens is arranged on a light path of the white LED light source; and a second Fresnel lens is arranged on a light pathof the yellow LED light source. The runway edge lamp is simple in structure and can save energy; meanwhile, the service life of the LED light sources is 50,000 hours, and the problem that light sources in an airport are frequently replaced is solved.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a runway edge light with two-way light. Background technique [0002] The runway edge light is a kind of guiding light for the pilot to identify the runway boundary when flying in the day and night (including take-off and landing). The light is a two-way light emitting light, and the light has strict requirements on light intensity, angle and color . [0003] Traditional runway edge lights generally use halogen tungsten lamps as the light source. The light source of halogen tungsten lamps is white light, while runway edge lights need yellow and white light, so it is necessary to add a yellow filter to absorb other light through the filter. The wavelength of light is used to obtain yellow light, which makes the structure of the lamp complex and wastes more absorbed light energy. At the same time, the halogen tungsten lamp emits light for the entire space at a 4π solid angle, while the runwa...

AI Technical Summary

Problems solved by technology

Existing runway edge lights that use LEDs as light sources generally use convex light distribution mirrors and reflectors for light distribution. The structure is complex, and structures such as reflectors must also be used. The divergence angle is large, which increases the reflection loss of light. , reducing light utilization

Moreover, the outgoing light angle of the pipeline is relatively large, which cannot well meet the requirements for the beam angle of the runway edge lights in the international / national standards of navigation lights
