Abstract
The present invention provides a metal halide discharge lamp emitting light from purplish red to pink. When the discharge lamp of the present invention is used, the inner side of a discharge lamp working in 25 to 50 W is filled with inert gas and mercury vapor, and is also filled with metal halides which can generate light from purplish red to pink. Chromaticity spots (x, y) of light colors are in a quadrangle which takes (0.3728, 0.2682) as the center and is surrounded by four spots of (0.2986, 0.2137), (0.3112, 0.2231), (0.3917, 0.2818), (0.4334, 0.2981); the quadrangle is in the region from purplish red to pink in a CIF 1961 xyz chromaticity diagram. The present invention is a decorative lighting lamp with long life or a decorative signal lamp for a car, and the output efficiency of red 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 long-life interior decoration and automobile-used decoration signal usefulness of being applicable to, glow color is from purplish red and discharge light with metal halide pink.
Background technology
Interior decoration directional lighting majority is directional lighting PAR lamp and the MR type tungsten halogen lamp that adopts the band reflective mirror at present, and this two classes lamp all is an incandescent lamp, so luminous efficiency has only 15～20lm/w.The local part of the decorative lighting that has needs ruddiness give prominence to decorative effect, so can only be on the mouthpiece cover of this class lamp the red glass sheet of ruddiness thoroughly only.Actual projected is very weak to the ruddiness on the photographed object, MR16 type low-voltage halogen tungsten such as a 50W, luminous efficiency is 16lm/w, and total light flux is 800lm, and wherein red light portion 25%, the ruddiness luminous flux has only 200lm, the red glass sheet is generally about 80% the transmitance of ruddiness, adds the reflecting condensation efficient optimum state 90% of reflective mirror, and the ruddiness light that goes out of actual projected is logical so has only 144lm, DeGrain can not satisfy the needs of use.
General lighting also can be adopted 35～70W small-power Metal halogen lamp, but the ruddiness ratio is less, the 3100K colour temperature Metal halogen lamp of high light efficiency, this light flux is 3200lm, removes reflective mirror spotlight effect 0.9, ruddiness sheet glass transmitance 0.8, red ratio only is about 14%; the last ruddiness sheet glass of Cover, power are that the luminous flux of the ruddiness launched of the 3100K colour temperature Metal halogen lamp of 35W has only about 320lm, so still do not reach desirable effect.
Summary of the invention
The purpose of this invention is to provide a kind of glow color from purplish red extremely pink interior decoration illumination and automobile-used decorative lighting discharge light with metal halide.
In order to reach above purpose, the present invention charges and discharge into the argon gas of 5000～50000Pa in working in the discharge tube of 25w～50W or charges into the high-pressure xenon of 400～900kPa, and charge into 3～13 milligrams/every cubic centimetre mercury vapour, charge into the metal halide of generation in addition from purplish red coloured light to pink, photochromic chroma point is on the CIE1931 chromaticity diagram, chroma point (X, Y) be positioned at X=0.3728, Y=0.2682 is the center, and with (0.3112,0.223), (0.2986,0.2137), (0.3917,0.2818), (0.4334,0.2981) in these 4 somes quadrangle scope of surrounding.
The metal halide that fills in the described discharge tube can comprise following type: the halide of (1) sodium and indium, total concentration are 2～10 milligrams/every cubic centimetre, and these the two kinds of halide always ratio of charging into are 0.16＜W
NaWeight %/W
InWeight %/＜0.85.(2) metal halide of lithium and indium, these the two kinds of halide always ratio of charging into are 0.16＜W

GaWeight %＜1, total concentration are 2～10 milligrams/cubic centimetre.(5) halide of lithium, sodium and indium, these three kinds of halid ratios of charging into are: W
LiWeight %=10%～50%, W
NaWeight %=80%～33%, W
InWeight %=10%～17%, total concentration are 2～10 milligrams/cubic centimetre.(6) halide of lithium, sodium and gallium, these three kinds of halid ratios of charging into are: W
LiWeight %=10%～50%, W
NaWeight %=80%～33%, W
GaWeight %=10%17%, total concentration is 2～10 milligrams/cubic centimetre.
Halogen in the metal halide of the present invention comprises bromine and iodine.
Discharge lamp of the present invention is under the 35W low power condition, the output radiation flux in 610nm～670nm ruddiness zone reaches 30～50% of total radiant flux, the output radiation flux of purple light reaches 20～35% of total radiant flux, the radiant flux of other color of light has only 20～35%, and therefore naked eyes look that ruddiness is denseer in the light beam of output.Wherein large red is that the light of 670nm has accounted for 3/4 in the ruddiness composition.
Discharge lamp of the present invention is exported 5 times of low-voltage halogen tungsten that ruddiness is a 50W under 35W small-power condition, 3 times of life-span are 35W than a power, and colour temperature is that the illumination of 3100K exceeds 1～2 times with the output of Metal halogen lamp ruddiness.
