Lamp apparatus mounted at center line at airport runway

Abstract

The invention relates to the field of civil aerodrome navigational lights, in particular to an airport runway center line light. The light is characterized in that: a light cover is provided with two concave holes. Each concave hole has a prism which is connected on a wall of an cavity in the light cover by a bolt. A bromine-tungsten light bulb is arranged under each prism and provided with a color filter and a light bulb protective casing. The bromine-tungsten light bulbs are arranged on a light bulb support. Upper part of inner cover is provided with a flat sealing ring and lower part of the inner cover is provided with an O-shaped sealing ring; the cavity of the light cover is connected with a top cover of a base through internal-external threads to form an integral light. Based on a theory of optical interference, the light can produce white or red light at different distances under the reflection of the prisms, the light beam ranges from negative 5 degrees to positive five degrees in a horizontal direction and from zero to 7 degrees in a vertical direction, and an average light intensity is 5000cd. Compared with the prior art, the light has the advantages of double-layer sealing structure, good waterproof property achieved by connecting an input wire with the inner cover with a waterproof plug, high shock and pressure resistance, capacity of bearing 13.34 KN horizontal shear without damaging structure or part displacement and looseness, and capacity of protecting a optical system from being damaged and parting from displacing when impacted in the top center by a 40 Joule steel ball.

Description

[technical field] [0001] The invention relates to the field of civil airport navigation aid lighting fixtures, in particular to an airport runway centerline light device. [Background technique] [0002] At present, the main problems of existing similar lamps in China are water leakage caused by poor sealing, and insufficient strength and easy damage. Generally, domestic lamps use outer sealing rings to prevent water leakage, which cannot effectively and permanently prevent the intrusion of rainwater and other sewage. , Once water leaks, it will seriously damage the bulb and wire, shorten the life of the lamp, and increase the maintenance cost. The impact on the lamp when the plane lands is very strong. [Content of the invention] [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a runway centerline light device with good water resistance and firm structure. [0004] In order to achieve the above purpose, an airport r...

Problems solved by technology

[0002] At present, the main problems of existing similar lamps in China are water leakage caused by poor sealing, and insufficient strength and easy damage. Generally, domestic lamps use outer sealing rings to prevent water leakage, which cannot effectively and permanently prevent the intrusion of rainwater and other sewage. Once the water leaks, it will seriously damage the bulb and wire, shorten the life of the lamp, and increase the maintenance cost. The impact on the lamp when the plane lands is very strong. If it cannot be shock-resistant and shock-absorbing, the bulb will be easily damaged.
