Embodiment Construction

[0026] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0027] see Figure 1 to Figure 4 , the light distribution system of the present invention includes a light source 1, and a prism 2, the prism 2 is an irregular quadrangular prism structure, and it has a light incident surface 21 and a light incident surface 21 that are oppositely arranged to allow the light from the light source 1 to enter. A light-emitting surface 22 for the light from the light source 1 to exit. The light-incident surface 21 is perpendicular to the central axis 11 of the light source 1. The light-incident surface 21 is provided with a plurality of sawtooth edges, and the plurality of sawtooth edges are along the The central line 211 has a left-right symmetrical distribution structure.

[0028] An embedded airport runway edge light of the present invention comprises the above-mentioned light distribution system, in which the central axis 11 of the l...

Abstract

The invention discloses a light distribution system and an embedded airport runway sidelight. The light distribution system comprises a light source and a prism. The prism has an irregularly quadrangular structure, and is provided with a light incident surface and a light emergent surface, wherein the light incident surface and the light emergent surface are opposite; the light of the corresponding light source can be incident into the light incident surface and emergent from the light emergent surface; the light incident surface is perpendicular to a central axis of the light source; and a plurality of saw-toothed edges are arranged on the light incident surface. The three prisms are arranged on the prism mounting plates in a flush way. The light distribution requirements of a runway sidelight on a 60m-wide runway and a runway sidelight compatible with a 45m-wide runway can be met with high luminous efficiency and high reliability.

Description

technical field [0001] The invention relates to airport navigation lighting equipment, in particular to a light distribution system for airport runway side lights. Background technique [0002] Existing airport runway edge lights mainly include vertical runway edge lights and embedded runway edge lights. Among them, the vertical runway edge lights are easily damaged and take up a large space. When the installation height is high, maintenance is inconvenient, and the aircraft will be damaged when it deviates slightly from the runway; the embedded runway edge lights occupy a small space, but the light intensity is difficult to reach international Color coding and intensity requirements specified by ICAO. In an embedded runway edge light disclosed in Chinese patent ZL200820154659.2, the light distribution system is composed of a light bulb, an optical prism and a color filter arranged between the light bulb and the optical prism. In the existing structure, a color filter need...
