Problems solved by technology

Therefore, during the test, if the traditional approach side lights completely cover the oblate elliptical light intensity curve required by the standard, a considerable part of the light beam will be irradiated outside the elliptical area, resulting in a waste of energy

Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention discloses an approach side lamp. The approach side lamp comprises a light source, a reflection cup and a lens; the reflection cup is hollow loudspeaker-shaped, the generating line of the reflection cup is a parabola, the reflection cup is provided with a big mouth end and a small mouth end, the light source is held in the reflection cup and is close to the small mouth end, and the big mouth end is a light outlet; the lens is mounted at the big mouth end of the reflection cup, the lens covers the light outlet and comprises a light incidence surface near the light source and a light emitting surface far away from the light source, the light emitting surface is provided with a plurality of bumps which extend vertically, and the cross section of each bump is triangular; light beams generated by the light source are reflected to the lens by the reflection cup and are emitted after being refracted by the bumps. A light intensity curve of the approach side lamp is flat elliptic, so that the approach side lamp does not need to waste energy to form the flat elliptic light intensity curve required by the industrial standard, and the energy is saved.

Description

technical field [0001] The invention relates to a special lamp for civil aviation, in particular to an approach side lamp. Background technique [0002] Approach refers to the process of flying the aircraft to the runway when it descends. In the approach phase, to adjust the altitude of the aircraft and align it with the runway to avoid ground obstacles, the pilot must concentrate on the operation accurately. Therefore, the approach has strict standards and operating procedures. [0003] Approach lights refer to the lights set on the airstrip to guide the sub-units to land, including the approach side lights set on both sides of the runway and the approach center line lights set on the center line of the airstrip. For the approach side lights, they need a certain irradiation area, so the industry standard requires their isoluminous intensity curves to be oblate ellipse. At the same time, in order for the pilot to clearly see the approach side lights on both sides of the ru...
