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]
The present invention relates to civil airport navaid field of illuminating lamps, specifically a kind of airfield runway center line lamp device.
[background technology]
At present, domestic existing similar light fixture, subject matter are the fragile problem of seepy question, insufficient strength that poor sealing causes, domestic general light fixture all adopts outer sealing ring to prevent leaking, the intrusion that prevents sewage such as rainwater that can't be effective, lasting like this, in case leak,, shorten lamp life with grievous injury bulb and lead, increase maintenance cost, the impact that brings to light fixture during aircraft landing is very strong, if can't accomplish antidetonation, shock-absorbing, bulb will be very easy to damage.
[summary of the invention]
The objective of the invention is to overcome the deficiencies in the prior art, a kind of have good water proofing property, well-set airfield runway center line lamp device are provided.
For achieving the above object, design a kind of airfield runway center line lamp device, comprise light cover, bromine tungsten-arc lamp bulb, inner cover, base, it is characterized in that light cover is provided with two shrinkage pools, respectively be provided with a prism in each shrinkage pool, prism is equipped with the prism cover outward, the prism pressing plate, the prism backplate, prism adopts screw to be connected on the light cover inner cavity wall, respectively be provided with a bromine tungsten-arc lamp bulb below each prism, filter is housed before the bromine tungsten-arc lamp bulb, the bulb sheath, bromine tungsten-arc lamp bulb is contained on the bulb rack, bulb rack is connected with inner cover with clamp by screw, the inner cover top is provided with the plain seal circle, the inner cover below is provided with the O RunddichtringO, light cover cavity and base top housing adopt internal and external threads to connect and compose light fixture integral body, described light fixture is provided with the double-layer seal coil structures, be provided with rubber washer and little stuffing-box binding post parts between described light fixture input lead and the inner cover to bulb, the other end between input lead and the inner cover is provided with the waterproof plug syndeton, described light fixture is according to the interference of light principle, under refraction by prism, different distances produce white light or ruddiness, and light beam scope horizontal direction is ± 5 degree, vertical direction is the 0-7 degree, average intensity 5000cd; The double-layer seal coil structures is made of plain seal circle and O RunddichtringO, and the O RunddichtringO is provided with inner cover, is provided with the plain seal circle on the inner cover again, forms double-deck waterproof grommet; The waterproof plug syndeton is by male adapter one end of lead one end connection cast molding, and jack one end that male adapter connects cast molding constitutes.
The present invention compared with prior art, simple in structure, novel, easy to use, safe and reliable, the double-layer seal coil structures, adopt waterproof plug to connect between input lead and the inner cover and have excellent waterproofness, antidetonation, anti-pressure ability are strong, and light fixture structural failure can not occur after the 13.345KN horizontal shear, parts displacement or loosening, with steel ball with 40J energy, impact the light fixture top center, the optical system of light fixture and parts can not produce and damage and displacement.
