Description

A kind of composite aircraft landing and taxing light

Technical field

The utility model relates to field of light fittings, is specifically related to appearance composite aircraft landing and taxing light.

Background technology

The aircraft landing taxiing light that uses at present is traditional incandescent lamp, is installed in respectively by glass screen and glass as the incandescent filament of landing light function and taxiing light function and bores in the confined space of forming.Incandescent lamp bulb is processed according to thermal-radiating principle, and radiant body (wick) is a tungsten filament; Electric current is emitted ohm heat during through tungsten filament, after tungsten filament is heated to uniform temperature, will produce very strong heat radiation, and wherein a part of radiation is positioned at visible region, changes electric energy into light.The landing and taxing light of being processed by incandescent lamp has following defective: the one; The landing light power consumption that this tungsten filament wick is processed is bigger; Generally all about several hectowatts, and most of energy distributes with the form of heat energy, and conversion efficiency is low; And owing to the energy on the aircraft is very valuable, this kind tengsten lamp consumes resources is big; The 2nd, because the tungsten filament evaporation rate is fast, its life-span, generally about tens hours, this kind landing headlight was low service life; The 3rd, because the tungsten filament anti-seismic performance is relatively poor, descend anti-seismic performance poorer especially in working order, the unstable properties of this kind landing headlight.

HID xenon gaseous discharge lamp is a kind of novel illumination light source of efficient, high reliability; HID is the abbreviation of High Intensity Discharge, HID xenon gaseous discharge lamp be with xenon ionization fluorescent tube as illuminator, luminous through gas discharge, have light efficiency height, low in energy consumption, advantage such as the life-span is long, resistance to shock is strong.If HID xenon gaseous discharge lamp is realized landing and sliding two kinds of functions, must an independent HID landing headlight and an independent HID aircraft taxi lamp be carried out the system integration; Two HID will need greatly to change the structure and shape of landing and taxing light, can not change the profile of existing aircraft landing taxiing light during owing to actual the use, so can't realize in this way.

The utility model content

The purpose of the utility model is to overcome the deficiency of prior art, and provide a kind of and can satisfy aircraft landing and slide instructions for use not changing the light fixture profile, and long service life, low in energy consumption, composite aircraft landing and taxing light that resistance to shock is good.

To achieve these goals, the technical scheme of the utility model employing is:

Said composite aircraft landing and taxing light comprises lamp bracket, is provided with the HID bulb at center, lamp bracket top, is positioned at HID bulb periphery on the lamp bracket top and is evenly distributed with led module; Be provided with the HID power supply that is used to drive the HID bulb in said lamp bottom; Be positioned at the LED constant-current supply that HID power supply periphery is distributed with the driving LED module in said lamp bracket bottom; Along the protruding joint end of said lamp bracket tip edge, on this joint end, clamp the lampshade that promising HID bulb and led module provide protection.

Said led module be distributed in pairs the HID bulb around, the every pair of led module is that symmetrical centre is symmetrically distributed with HID bulb center all.Said led module be a pair of more than.

Said led module is made up of great power LED and lens, and said lens are located on the said lamp bracket position near said lampshade.

Lens and HID bulb and lampshade over against a side top be positioned on the same plane.

Said lampshade is made up of snap ring and quartzy slide, and said quartzy slide is adhered on snap ring one side; Said lampshade is installed on the joint end of said lamp bracket through said snap ring opposite side.

The technical scheme that said composite aircraft landing and taxing light adopts has the following advantages:

At first, composite aircraft landing and taxing light, HID bulb have that hot spot is concentrated, the high characteristics of brightness, satisfy the requirement of landing light to high brightness; Secondly, work the simultaneously luminance index that can satisfy taxiing light of a plurality of high-power LED modules can satisfy the requirement of angle of scattering again simultaneously; Secondly, quartzy slide is bonded on the snap ring, the effect that can play printing opacity can make again and form airtight space in the lamp bracket, and HID bulb and led module are played a protective role, and avoids outside adverse circumstances it is exerted an influence again; At last, the LED volume is little, and efficient is high, and is easy to use, its long service life; The HID bulb life is long, resistance to shock is strong; With HID bulb and led module combination, the composite aircraft landing and taxing light has the advantage of HID bulb and led module concurrently, and not only long service life, low in energy consumption, and resistance to shock is good; And it need not change under the contour structures situation, can satisfy the work requirements of landing and taxiing light.
