Abstract
The utility model relates to the field of civil airport navigation lighting fixtures, in particular to a grounding zone light. The grounding zone light is characterized in that a concave hole is formed in the middle of a light cover, an optical prism and a bulb are arranged in the concave hole, a color filter is arranged between the bulb and the optical prism, the bulb is arranged on an inner shade through a bulb support, one end of the inner shade is connected with the bottom part of the light cover and arranged in a cavity of a base, the light cover and the base are provided with bolts for connection, thereby constituting the light. According to the light interference principle, light at the different distances can generate white light or yellow light under the refraction by the optical prisms, the scope of a main light beam is plus or minus 5 degrees horizontally and 2-9 degrees vertically, and the average light intensity of the white light is not less than 5000cd. Compared with the prior art, the grounding zone light has simple and novel structure, and convenient, safe and reliable use, the light cover, a light body and the inner shade all adopt special aluminium alloy for die casting, thereby having corrosion resistance, light weight, good seismic and anti-pressure properties; the grounding zone light further comprises a dual-layer sealing ring structure, an input guide wire and the inner shade are connected by adopting a water-tight plug, thereby having good waterproof property.
Description
[technical field]
The utility model relates to civil airport navaid field of illuminating lamps, specifically a kind of touchdown zone light.
[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 purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of good waterproof performance is provided, the touchdown zone light that shock resistance is strong.
For achieving the above object, design a kind of touchdown zone light, comprise light cover, inner cover, bulb, optical prism, base, it is characterized in that being provided with a shrinkage pool in the middle of the light cover, be provided with an optical prism and a bulb in the shrinkage pool, be provided with colour filter between bulb and the optical prism, bulb is installed on the inner cover by bulb rack, and inner cover one end connects the light cover bottom and places in the base cavity pocket, and light cover is provided with bolt with base and is connected, form light fixture, according to the interference of light principle, different distance light produces white light or ruddiness under the optical prism refraction, main beam scope level ± 5 degree, vertical 2-9 degree, average intensity white light 〉=5000cd; Described light fixture is provided with the double-layer seal coil structures, is connected with waterproof construction between input lead and the inner cover; Described double-layer seal coil structures is that light cover and base junction are provided with sealing ring, and inner cover and light cover junction are provided with sealing ring; Waterproof construction is provided with the weather proof receptacle of waterproof in the cavity of base, described weather proof receptacle adopts the rubber and plastic plug of casting to combine with socket, in order to being connected of lead and bulb; Light fixture can bear
Vertical static load.
The utility model compared with prior art, simple in structure, novel, easy to use, safe and reliable, light cover, lamp body, inner cover all adopt particular aluminum alloy to be cast into, corrosion-resistant, in light weight, antidetonation, crushing resistance are good, the double-layer seal coil structures adopts weather proof receptacle to connect between input lead and the inner cover, have excellent waterproofness.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
