Background technology
In EP 0 370 318 A2, such as disclose a kind of described Halogen lamp LED.The document describes a kind of Halogen lamp LED for working under high temperature, it has the fluorescent tube of printing opacity and is arranged on the tungsten filament in this fluorescent tube and is arranged on the filler of this fluorescent tube inside, wherein, filler comprises the mixture be made up of carbon, hydrogen, inert gas, phosphorus, chlorine and bromine.The combination total amount of chlorine and bromine and the mol ratio of carbon are greater than 1, and the mol ratio of the combination total amount of phosphorus and chlorine and bromine is in the scope of o. 5 to 2.The GN 2, xenon, krypton, argon or helium D is used to describe a kind of miniature halogen lamps in EP 1 255 279 A2 as inert gas suggestion, keep low as far as possible to make the evaporation rate of tungsten in tungsten filament, the filler of this miniature halogen lamps has from 0.5 megapascal (MPa) to the cold stuffing pressure within the scope of 3 megapascal (MPa)s, and its noble gas component comprises xenon.In fluorescent tube substantially and, amount uses inert gas disorderly very high as filler composition cost.
Summary of the invention
Task of the present invention is to provide a kind of Halogen lamp LED of described type, and this Halogen lamp LED can with different power work, and can not significantly blackening at its length of life fluorescent tube.
According to the present invention, this task is solved by the feature of claim 1, describes particularly preferred embodiment of the present invention in dependent claims.
According to Halogen lamp LED of the present invention, there is at least one and be arranged on the tungsten filament of light-transmitting lamp vessel inside and the filler in fluorescent tube, wherein, this filler comprises halogenic ingredient for halogen cycle process and noble gas component, according to the present invention, cold stuffing pressure in fluorescent tube is more than or equal to 0.7 megapascal (MPa), and noble gas component comprises the other inert gas of krypton or xenon and at least one, its atom has the atomic radius less than krypton atom Wu.
Ensure that Halogen lamp LED can with different power work and fluorescent tube can not obviously blackening thus.The high cold stuffing pressure of combination inert gas krypton or xenon is conducive to tungsten evaporation rate small in tungsten filament.Except krypton or xenon, noble gas component comprises another kind of inert gas, and its atom has the atomic radius less than krypton atom.Already showed, improved the heat delivery from least one tungsten filament to fluorescent tube by this other inert gas.Thus in order to keep halogen cycle and avoid fluorescent tube blackening in aforementioned operation states or working stage, when working under the power reduced in other words when lamp dimness work and ensure that within the operating time of lamp short time fluorescent tube fully heats.
So, use according to the light source that Halogen lamp LED of the present invention is especially suitable as in static direction indicator lamp, direction indicator lamp is the just short time connection when flowing slowly over bend in order to illuminate side street when turning round in automobile heat detecting illuminator, or assists the short time to connect as parking.In addition, according to Halogen lamp LED of the present invention be also applicable to as day portable lighter and positioning lamp combinationally use.By day Halogen lamp LED as day portable lighter with the vehicle complete vehicle supply voltage of such as 12 volts work, and at night as positioning lamp with the vehicle complete vehicle supply voltage work being roughly half of about 6 volts.
Preferably do not use xenon, and only use krypton, and use neon or argon as other inert gas.Neon and argon are all conducive to improving delivered heat in above-mentioned meaning.According to preferred first execution mode of the present invention, except krypton, use argon as other inert gas, wherein the dividing potential drop of inert gas argon is preferably less than or equal to 80% of cold stuffing pressure in fluorescent tube.According to preferred second execution mode of the present invention, except krypton, use neon as other inert gas, wherein the dividing potential drop of inert gas neon is preferably less than or equal to 40% of cold stuffing pressure in fluorescent tube.According to preferred second execution mode of the present invention, except krypton, neon had both been used also to use argon as other inert gas.
In order to make the tungsten evaporation rate of described at least one tungsten filament keep lower, the dividing potential drop of inert gas krypton xenon is in other words preferably greater than or equal to 20% of cold stuffing pressure.
In order to realize halogen cycle process, the share of halogen atom in filler is preferably in 100ppm (PPM) in the scope of 600ppm.The excessive concentrations of halogenic ingredient or metering may cause fluorescent tube being formed sedimentary deposit and on colder metal position, cause material denudation in other words.
In order to remove the dirt in fluorescent tube, such as, in the manufacture process of lamp, enter the dirt of fluorescent tube, phosphorus or phosphorus compound are preferably set in fluorescent tube as getter.
In order to continue to heat fluorescent tube at work, fluorescent tube can be provided with coating, this coating absorbs a part for the electromagnetic radiation produced by least one tungsten filament or is reflected back in fluorescent tube, this coating is such as the interference filter of the printing opacity on lamp tube outer surface, and the infrared radiation reflection that tungsten filament is launched to be returned in fluorescent tube and ensured the additional heating of lamp by it.This coating that replaces also can be the recuperation layer of printing opacity, and recuperation layer absorbs infrared radiation and is conducive to the heating of fluorescent tube by this way.For this reason, fluorescent tube such as can have a kind of suitable color.
