Abstract
The present invention provides a metal halide discharge lamp emitting light from green yellow to yellow. Inert gases and mercury vapor are filled into the discharge lamp tube of the discharge lamp of the present invention working at 25 to 50w, and then metal halide emitting light from green yellow to yellow is filled into the discharge lamp tube. Chromatic spots of light color (x, y) is positioned in the range of a quadrangle that takes (0.412, 0.4336) as a center and is surrounded by the four points of (0.452, 0.421), (0.468, 0.448), (0.348, 0.432) and (0.360, 0.419). Under the condition of 35 W of small power, the output of green-yellow and yellow light of the discharge lamp of the present invention is 7 to 8 times higher than an H type tungsten halogen lamp, and is 3 to 4 times higher than the yellow light part of a common automobile metal halide lamp with a color temperature of 4000K to 6000K to make the penetrativeness and the range of a fog lamp 2 to 3 times longer. The present invention is also a decorative lighting lamp with long life, and the efficiency of outputting green yellow light to yellow light of the present invention is superior to other light sources.
Description
Technical field
The present invention relates to a kind of low power metal halide discharge lamp, especially a kind of low power metal halide discharge lamp that is applicable to automobile-used preceding photograph fog lamp and long-life interior decoration illuminating lamp.
Technical background
At present, the mist transmitting performance of car headlamp is not very strong, generally all used the H type tungsten halogen lamp of colour temperature 3000K as the fog lamp light source according to fog lamp before the automobile in the past, the front panel glass of fog lamp light fixture is the yellow glass plate of a saturating gold-tinted, this fog lamp only appears and accounts for total light logical about 1/2 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 (being commonly called as xenon head lamp or HID headlight), all improve a lot as dipped headlights, 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 also lower, compare as dipped headlights, high beam as fog lamp is many, seem too dark, haze-penetrating capability is limited.In recent years, for example proposed to be coated with the multi-coated interference film of last layer yellow in Ri Ben the patent (spy opens flat 5-325895 communique) in the case surface of HID auto lamp, 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 1/2.
Interior decoration directional lighting at present, majority are directional lighting PAR lamp and the MR type tungsten halogen lamps that adopts the band reflective mirror, and this two classes lamp all is an incandescent lamp, and luminous efficiency has only 15～20lm/w.The decorative lighting photographed object part that has needs gold-tinted to give prominence to decorative effect, so can only be on the mouthpiece cover of this class lamp the yellow glass sheet of an only saturating gold-tinted, therefore the gold-tinted of actual projected to the photographed object a little less than, such as, the MR16 type low-voltage halogen tungsten of a 50W, luminous efficiency is 16lm/w, total light flux is 800lm, wherein gold-tinted part 50% is that the gold-tinted luminous flux has only 400lm, and the transmitance of yellow slide is generally about 80%, adds the light projector efficient optimum state 90% of reflective mirror, the gold-tinted luminous flux that goes out of actual projected has only about 280lm so, in order to reach positive effect, can only increase flood light lamp number sometimes, power consumption is very big.
Summary of the invention:
The purpose of this invention is to provide a kind of glow color from green-yellow to sodium yellow, the low power metal halide discharge lamp of very strong haze-penetrating capability is arranged, be particularly useful for automobile-used before according to the illumination of fog lamp and interior decoration.
In order to reach above purpose, the present invention is the lithium that produces 6700K ruddiness on adding on the basis of original patented technology, has therefore widened the scope of allotting gold-tinted, makes yellow denseer darker.Technical scheme of the present invention is as follows: charge into the high-pressure xenon of 400～900Kpa or charge into the argon gas of 5000～50000Pa in working in the discharge tube of 25～50W, and charge into 3～13 milligrams/every cubic centimetre mercuryvapour, charge into the metal halide of generation in addition from greenish-yellow coloured light to sodium yellow.(x, the y) of photochromic chroma point on the CIE1931 chromaticity diagram is positioned at the quadrangle scope with (0.452,0.421), (0.468,0.448), (0.348,0.432), (0.360,0.419) these 4 encirclements.
The metal halide that fills in the described discharge tube can comprise following two types: the 1. halide of lithium and thallium, described metal halide total concentration is 2～12 milligrams/cubic centimetre, and these the two kinds of halide always ratio of charging into are the halide weight percentage W of 0.5＜lithium metal
LiThe halide weight percentage W of %/thallium
T1%%＜4.2. the halide of lithium, sodium and thallium, described metal halide total concentration is 2～15 milligrams/cubic centimetre, these the three kinds of halide always ratio of charging into are, in the total weight of whole metal halides: the halide weight percentage W of lithium metal
Li%=10～60%; The halide weight percentage W of sodium metal
Na%=20～80%; The halide weight percentage W of thallium
T1%=10～20%.
Halogen in the metal halide of the present invention comprises iodine.
Discharge lamp of the present invention is under the 35W low power condition, the 535nm green glow reaches 90% of global radiation luminous flux to the output radiation luminous flux in 670nm ruddiness zone, and the various sodium yellows that green glow, ruddiness just can be allotted from greenish-yellow to pale brown by different proportion satisfy the requirement that interior decoration throws light on.The output of gold-tinted exceeds 6～7 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 improve 1～2 times.
