Abstract

The utility model discloses an airplane landing taxing light used when the airplane is flying and landing, which comprises a glass screen, a glass cone, a reflective film layer, a light source, a light source bracket, a metal halide lamp core, a contact piece insulator and a quick-start electronic ballast. The landing taxiing light adopts the metal halide lamp core as a main lighting body; the metal halide lamp cores of different powers can give out facula with different luminous flux, color temperature and light intensity distribution to meet the landing taxing demand of airplane. The airplane landing taxiing light can effectively reduce the problems of low light efficiency, large heat, easy explosion and fusing, and the like, of the traditional tungsten filament light source, and improvethe service life as well as safety and reliability of bulbs.

Description

A kind of aircraft landing taxiing light

Technical field

The utility model patent relates to a kind of type aircraft landing and taxing light, is used for aircraft floor light when landing and sliding.

Background technology

It generally is high-power enclosed type incandescent lamp that light source is slided in the aircraft landing of using at present.Incandescent lamp is made according to heat radiation principle, by electric energy filament is heated to incandescent state and luminous, and filament also will produce a large amount of infra-red radiations and a spot of ultra-violet radiation when electric energy is transformed into visible light.In order to satisfy the actual instructions for use of aircraft, generally select the incandescent lamp of low-voltage, big electric current, high colour temperature for use, such incandescent lamp has characteristics such as light efficiency is low, heat is big, the life-span is short, easily gas leakage, easy burning silk.

Summary of the invention

Goal of the invention: at the deficiencies in the prior art, the utility model provides a kind of aircraft landing to slide, and can improve the light efficiency of landing light, reduces the power of lamp, reduces heat, increases the service life, and does not burn advantages such as silk, and integral body has improved the security reliability of bulb.

Technical scheme: the utility model is realized by following technical scheme:

Aircraft landing taxiing light of the present utility model, comprise glass screen, glass awl, reflective coating, light source and light source bracket, contact chip insulator and start electric ballast fast, its inner illuminating source is the metal halide wick, and the outside has quick startup ballast to link to each other with described contact chip insulator.

Metal halide wick of the present utility model can be selected different power (35W～150W) and different colour temperature (3000K～6500K).

Metal halide wick of the present utility model in addition can also adopt pottery or two kinds of materials of quartz glass as shell.

Metal halide lamp core housing of the present utility model can also be designed to spherical or cylindrical.

Reflective coating of the present utility model can also be designed to infrared external reflection rete or aluminium film.

Further be that cover top portion diameter of the present utility model is 90～204mm, highly is no more than 90mm.

Beneficial effect: compared with prior art, the utlity model has following advantage.

(1) adopt the metal halide wick, light efficiency can be brought up to 120lm/w by the 20lm/w of ordinary incandescent lamp.Just can reach the incandescent lamp of 450W power with its light efficiency of wick of 100W power.Lower the power consumption of landing and taxing light effectively, reduced the heat that discharges, improved reliability of products.This wick is the gas-discharge lamp wick in addition, and no filamentray structure has been avoided problems such as the burning silk of tungsten light source, the weak point that shakes, life-span weak point.

(2) adopt infrared reflection film, the reflectivity of visible light is reached more than 95%, can improve the central light strength about 20% of lamp.Unwanted wave band can be filtered or ends simultaneously.

Satisfy the needs of different occasions.

Wherein: 1, glass screen, 2, the glass awl, 3, reflective coating, 4, support, 5, the metal halide wick, 6, the contact chip insulator, 7, start electric ballast fast

The specific embodiment

As shown in Figure 1 and Figure 2, present embodiment is by glass screen 1, glass awl 2, and reflective coating 3, light source bracket 4, starts electric ballast 7 fast and constitutes metal halide wick 5, contact chip insulator 6.

During making, at first on glass awl 2 saturating infrared external reflection rete of evaporation or aluminium film as reflective coating 3.And the metal halide wick 5 that will select for use is welded on the light source bracket 4, and then with the metal halide wick 5 that assembles, the mode by the silver-bearing copper weldering is fixed on the focus of glass awl 2.Can adjust the distance of off-focal this moment according to different light distribution requirements.The glass awl 2 and the glass screen 1 that assemble metal halide wick 5 are carried out sealing-in, toast exhaust after the sealing-in, fill suitable inert gas, burn-on contact chip insulator 6 to prevent from when starting, to produce the arcing of instantaneous pressure at the shell of lamp.Connect quick startup electric ballast 7, connect rated operational voltage, light the present embodiment bulb and carry out the burn-in screen test, reject defective work.Design can the adopting quartz glass shell during landing light, can select the metal halide of ceramic package during the design taxiing light.

The present embodiment of making by above-mentioned technology has the light efficiency height, and power consumption is little, and heat discharges few, does not burn advantages such as silk, long service life, and the security reliability of bulb is enhanced.
