Example Embodiment

[0034] Such as figure 1 As shown, the present invention provides a navigation light 7 comprising: a light source 1, a transparent lampshade 2, a reflective mask 3, and a bottom plate 4. The reflective mask 3 and the transparent lampshade 2 are connected as a whole and fixed to the bottom plate together. 4, the light source 1 is arranged on the bottom plate 4 and is close to the reflection mask 3, and the light emitted by the light source 1 is reflected by the reflection mask 3 and then exits the transparent lamp cover 2.

[0035] In order to make the navigation light 7 of the present invention have a compact navigation light structure and reduce the aerodynamic influence under the premise of ensuring the light distribution, the mask of the present invention must be specially designed.

[0036] The light intensity distribution of the white light navigation light system must meet the following minimum requirements. Considering the light attenuation during use, the actual light intensi...

Abstract

The invention discloses a navigation lamp. The navigation lamp comprises a light source, a transparent lamp shade, a reflecting face cover and a bottom plate, wherein the reflecting face cover and the transparent lamp shade are connected into a whole and are fixed on the bottom plate together; the light source is arranged on the bottom plate and is close to the reflecting face cover; light rays emitted by the light source are reflected by the reflecting face cover and then emitted from the transparent lamp shade. The navigation lamp has a compact structure, and reduces pneumatic influence on the premise of ensuring light distribution.

Description

Technical field [0001] The invention relates to the field of aviation lighting, and more particularly, to the structural design of a navigation light. Background technique [0002] In the aircraft field, navigation lights are used to mark the flight direction of the aircraft and provide navigation information to surrounding aircraft. Generally speaking, a navigation light system must include a front navigation light and a rear navigation light. The front navigation light is composed of a left red light and a right green light, with the distance between them as large as possible, and the rear navigation light is a white light. [0003] The current navigation light products include two categories with halogen lamps or LEDs as light sources. Among them, LED light sources have the characteristics of high efficiency, long life, and high reliability. Therefore, LED navigation lights are becoming the development trend of navigation lights. [0004] In order to meet airworthiness requiremen...
