Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0022] see Figure 1~Figure 4 , a narrow-beam airport taxiway center line light provided by an embodiment of the present invention includes an upper shell 1 and a lower shell 2 matched with the upper shell 1. The lower shell 2 is provided with two prisms 3 with the same shape and arranged symmetrically and a The light source 4 at the middle position below the two prisms 3, the optical axis direction of the light source 4 is perpendicular to the ground, and a filter 5 is arranged between the light source 4 and the two prisms 3, and the filter 5 can be a yellow filter or a green filter .
[0023] The distance between the two prisms 3 is M=1~5mm, the prisms 3 are of irregular quadrangular prism structure, and the four side walls of the prisms 3 are successively connected to a li...

The invention discloses a narrow-light-beam airport taxi track central line lamp. A prism is designed to be in a specific shape, the position of a light source relative to the prism is limited, light rays of the light source can only go in from a light inlet of 36 + / - 0.5 mm * 30 + / - 0.5 mm in a light inlet face of the prism and go out from a light outlet face of 14 + / - 0.5 mm * 9.3 + / - 0.5 mm of the prism, so that the light rays which go out from a light outlet are changed to yellow light or green light of narrow light beams, the yellow light or the green light of the narrow light beams cannot intersect with light rays emitted by other indicating lamps nearby, lighting and indicating effect of the other indicating lamps is guaranteed, and accordingly the problem that an existing airport taxi track central line lamp emits wide-light-beam yellow light or wide-light-beam green light so that lighting and indicating of other indicating lamps are affected is solved. In addition, the narrow-light-beam yellow light or the narrow-light-beam green light emitted by the narrow-light-beam airport taxi track central line lamp also meets light distribution requirements on an airport taxi track of the convention on international civil aviation.
Description
technical field [0001] The invention relates to an airport taxiway center line light, in particular to a narrow beam airport taxiway center line light. Background technique [0002] According to international standards, the light emitted by the airport taxiway center line lights is green or yellow, which is used to guide the driver. At present, due to the wide green or yellow light beams emitted by the existing taxiway center line lights, the light emitted by the taxiway center line lights will intersect with the light emitted by other nearby indicators, thereby affecting the lighting and lighting of other indicators. indication effect. Contents of the invention [0003] The object of the present invention is to provide a narrow-beam airport taxiway center line light, which solves the problem in the prior art that the wide-beam airport taxiway center line light affects the illumination and indication of other indicator lights due to its wide beam. [0004] In order to so...
