Abstract
This invention provides a mobile metal halid discharge lamp, which injects high pressure xenon gas of 400 to 900Kpa into the discharging tube of 35W to 50W and injects mercury vapor 3.3 to 15 mg per cu.cm and injects yellow metal xenon, wherein the light color chroma point (x,y) with x is 0.465 and y is 0.38 in the enclosure trapezia of four points of (0.41,0.44), (0.405,0.46), (0.45,0.35), (0.48,0.35).
Description
Technical field
The present invention relates to automobile-used discharge light with metal halide, especially a kind of preceding discharge light with metal halide of automobile that is applicable to according to fog lamp.
Background technology
At present, the mist transmitting performance of car headlamp is not very strong.In the past, generally all use the H type tungsten halogen lamp of colour temperature 3000K as the fog lamp light source according to fog lamp before the automobile, the front panel glass of fog lamp light fixture is the yellow glass plate of saturating gold-tinted only, and this class fog lamp only appears and accounts for total light logical about 1/3 Huang, green glow, and actual Penetrating Fog penetration capacity is very weak.Popularizing in recent years and using 35W high pressure xenon metal halide discharge lamp (to be commonly called as the xenon head lamp, or HID headlight), all improve a lot as dipped beam, lamp high beam irradiating width and range, but the 35W Xenon gas metallic halogen lamp since colour temperature more than 4000K, the gold-tinted part is less, as fog lamp with compare as dipped headlights, high beam, seem too dark, haze-penetrating capability is limited.The multi-coated interference film of last layer yellow has been proposed to be coated with in the case surface of HID auto lamp in for example Japanese in recent years patent (spy opens flat 5-325895 communique), the colour temperature of the lamp of 4000K colour temperature is reduced to 2000～3500K, though after coating this tunic, the photochromic gold-tinted that become of Metal halogen lamp, but lost many light too, the gold-tinted that irradiates still only account for former total light logical about 1/3.
Summary of the invention
The purpose of this invention is to provide a kind of Gao Guangtong, have stronger penetration capacity and more long range automobile-used discharge light with metal halide.For reaching above purpose, the present invention charges into the high-pressure xenon of 400～900Kpa in the discharge tube inside that works in 35W～50W, and charges into 3.3～15 milligrams/every cubic centimetre mercury vapour, and charge into the metal halide that produces gold-tinted, photochromic chroma point is on the CIE1931 chromaticity diagram, and (x y) is positioned at X=0.465 chroma point, Y=0.38 is the center, and with (0.41,0.44), (0.405,0.46), (0.45,0.35), in the trapezoidal scope of (0.48,0.35) these 4 encirclements.
The metal halide that charges in the described discharge tube can be the halide of 100% sodium, and total concentration is 2～10 milligrams/every cubic centimetre.The metal halide that charges in the discharge tube also can be the halide of sodium and thallium, and these the two kinds of halide always ratio of charging into are 0.3＜W
NaWeight %/W
T1Weight %＜1,2～10 milligrams/every cubic centimetre of total concentration.
Halogen among the present invention in the metal halide comprises bromine and iodine.
Discharge lamp of the present invention is at the 35W low power condition, and gold-tinted output exceeds 5～6 times than H type tungsten halogen lamp, partly improves 1～2 times than the gold-tinted in the 4000K～6000K colour temperature automobile Metal halogen lamp commonly used, makes the penetration capacity of fog lamp and range grow 1～2 times.
