AIRFIELD EMBEDDED AID-TO-NAVIGATION LIGHT
Document Type and Number:
WIPO Patent Application WO/2020/238145
Kind Code:
A1
Abstract:
Disclosed is an airfield embedded aid-to-navigation light which is aimed at solving the problems of existing lights having a complicated structure, low light emission efficiency, etc., and which falls within the field of aid-to-navigation light devices. The aid-to-navigation light comprises a light device main body, which comprises a light upper cover (1), a pressing plate (5), a light-emitting device (4), a light inner cover (3), an upper-cover upper surface (14) and an upper-cover lower surface (16), wherein the light upper cover (1) is provided with at least one window, a prism (2) is arranged at the window, the middle of the light upper cover (1) is provided with a crossbar, the light-emitting device (4) is mounted on an inclined plane of the crossbar, and the pressing plate (5) and a driving circuit board are mounted on the upper-cover lower surface (16). The prism (2) of the airfield embedded light device is a pentagonal prism (2), such that the structure is simple, and the size is small; the prism (2) and the light upper cover (1) are connected in a sealed manner by means of sealing silica gel so as to achieve better sealing performance and higher stability as compared with traditional sealing with a glass sealant cover; and after being refracted twice by the pentagonal prism (2), light can be emitted from the window, which has a limited area, and the loss is low.
