Description

Ceramic metal helide lamp, its using method and ligthing paraphernalia
Technical field
The present invention relates in luminous tube, use metal halide lamp, its using method of light transparent ceramic and used its ligthing paraphernalia.
Background technology
As the conventional art relevant, one or more technology (opening clear 52-31581 communique with reference to the Japanese documentation spy) of the iodide of having enclosed inert gas, mercury, thallium iodide and iodate dysprosium, Holmium triiodide and other rare earth metal in the luminous tube of quartz system is arranged with the present invention.In addition, also known following technology promptly, in the light transparent ceramic luminous tube, is employed rare gas and mercury with rising, and has enclosed the iodide (opening the 2001-266791 communique with reference to the Japanese documentation spy) of holmium, dysprosium, thulium, sodium, thallium, cerium etc.
Open in the metal halide lamp of being put down in writing in the clear 52-31581 communique the spy as the patent documentation of Japan, the tube wall load of luminous tube is 10～12.5W/cm 2, luminous efficiency is 78～82.5lm/W, it is 70～80 that average color reproduces index Ra.Therefore this lamp for fear of the reaction of enclosing thing and quartz material, can't bring up to 20W/cm with tube wall load owing to used quartz in luminous tube 2More than.Thus, just there are luminous efficiency and average color to reproduce the shortcoming of index Ra difference.Therefore, this lamp is the lamp that is unsuitable for the room lighting purposes.
Open in the metal halide lamp of being put down in writing in the 2001-266791 communique spy as the patent documentation of Japan, in the luminous tube of ceramic, with rare gas and mercury, contain iodate dysprosium, iodate thulium, Holmium triiodide, thallium iodide, sodium iodide and cerous iodide.In addition, its tube wall load is set to 29.9W/cm 2
Up to now, in metal halide lamp, all want the design stability device for every kind of lamp.That is,, do not have the stabilizer of versatility as the metal halide lamp purposes.Consequently, owing to do not produce effect in batches, therefore the high problem of stabilizer price is arranged.On the other hand, in the stabilizer that high-pressure mercury-vapor lamp is used,, therefore produce in batches according to the stabilizer with versatility of standard owing to be to wait required standard by Japanese Industrial Standards (JIS).Consequently, because of producing effect, the stabilizer low price that high-pressure mercury-vapor lamp is used in batches.And, on market, there are a large amount of standard items to sell.
If the stabilizer that can use high-pressure mercury-vapor lamp to use in metal halide lamp then can obtain to use at an easy rate the advantage of metal halide lamp.And, can also obtain following advantage, that is, in the lighting device that the high-pressure mercury-vapor lamp that has used is used, can directly use metal halide lamp in market.
But, when the stabilizer of using with high-pressure mercury-vapor lamp uses in the past metal halide lamp, then have the problem that can't obtain sufficiently high lamp power factor.Here, so-called lamp power factor is a value of utilizing following formula to try to achieve.
Lamp power factor=lamp power W/ (be applied to voltage on the lamp * flow through the electric current of lamp)
In addition, as the material of the luminous tube of metal halide lamp, in general use quartz or light transparent ceramic.Used the metal halide lamp of light transparent ceramic to be known as ceramic metal helide lamp.Quartzy comparing in thermal endurance with light transparent ceramic is wanting in.So when using quartz, the upper limit of tube wall load reaches 20W/cm 2About.But,, need further to improve tube wall load in order to improve lamp efficient.In such cases, will use and compare the more good light transparent ceramic of thermal endurance with quartz.But the cost of light transparent ceramic will be higher than quartz.So in general light transparent ceramic is used to be higher than significantly the tube wall load (50W/cm that has used quartzy situation 2～60W/cm 2About) lamp in.And so-called lamp efficient is meant the luminous flux of unit power, by with lm/W unit representations such as (lumens/watt).
As mentioned above, when having used light transparent ceramic, utilize high tube wall load can obtain high lamp efficient.But, the problem that high tube wall load can bring the lamp power factor to reduce.Under using,, therefore just can not produce this kind problem owing to stabilizer can be designed to make the lamp power factor reach 1 basically to the situation of this lamp with the stabilizer that designs.But, be used at the stabilizer that high-pressure mercury-vapor lamp is used under the situation of metal halide lamp, owing to can't realize the optimal design of stabilizer, so the reduction of this lamp power factor just becomes serious problem.In order to address this problem, in general improve the lamp power factor by making luminous tube contain cerium halide.The amount of the cerium halide of this moment is adjusted to, and with respect to the molal quantity of the metallic element in halogenation dysprosium contained in the luminous tube, halogenation thulium, halogenation holmium, erbium halide and the halogenation terbium, the molal quantity of the Ce elements of cerium halide reaches more than 20%.
But hope can further improve lamp power factor and lamp efficient.But when improving tube wall load, the lamp power factor will reduce, and when reducing tube wall load, lamp efficient will reduce.So, even adjust tube wall load, also have can't obtain lamp power factor and lamp efficient both sides all high problem.
Summary of the invention
The objective of the invention is to, solve described problem, provide the stabilizer that promptly uses high-pressure mercury-vapor lamp to use to use ceramic metal helide lamp, the lamp that lamp power factor and lamp efficient both sides are very high.

At tube wall load is 25W/cm 2In the following zone, distinguish and to obtain from 50W/cm 2Near result is unexpected result fully.That is, although at 50W/cm 2Near, under the many situation of the cerium halide amount of reduction in luminous tube of the lamp power factor that causes by the rising of tube wall load and all be same degree under few situation, yet be 25W/cm at tube wall load 2In the following zone, the difference of the lamp power factor that causes by the difference of cerium halide amount obviously diminish (with reference to Fig. 5).On the other hand, under the situation that the cerium halide amount of degree in luminous tube of the minimizing of the lamp efficient that is caused by the reduction of tube wall load is many and all be same degree (with reference to Fig. 4) under few situation.Consequently, by following combination, that is, tube wall load is made as 22～25W/cm 2And with respect to the molal quantity of the metallic element in halogenation dysprosium contained in the luminous tube, halogenation thulium, halogenation holmium, erbium halide and the halogenation terbium, the molal quantity of the Ce elements of cerium halide contained in the luminous tube is made as below 10%, even then when the stabilizer of using with high-pressure mercury-vapor lamp is lighted ceramic metal helide lamp, also can obtain all high lamp of lamp power factor and lamp efficient two aspects.This result is waited first by the present application people and finds.
In addition, when tube wall load greater than 25W/cm 2The time, then can make the rising of the modulating voltage in the life-span become big etc., the life characteristic variation of lamp.In addition, when tube wall load less than 22W/cm 2The time, then the efficient of lamp reduces sharp.This be considered to because, the luminous tube temperature descends, the vapour pressure of luminescent substance reduces sharp.
As can be known from Fig. 6, the modulating voltage rising value of lighting after 12000 hours increases when tube wall load becomes big.At tube wall load is 22～25W/cm 2Scope in, the modulating voltage rising value is limited in the 10V basically, and when tube wall load greater than 27W/cm 2The time, then the modulating voltage rising value just increases to more than the 20V.
As can be known from Fig. 7, the crest voltage of lighting after 12000 hours increases greatly with the tube wall load change.At tube wall load is 22～25W/cm 2Scope in, crest voltage is 0～2V, and when tube wall load at 27W/cm 2When above, then crest voltage is just greater than 5V.
When the improving effect and represent of the reduction of reduction that the described modulating voltage that is caused by the minimizing of tube wall load is risen and crest voltage, then as shown in Figure 8 with the quencher incidence of lamp.As can be known from Fig. 8, the quencher incidence of lighting the lamp after 12000 hours is 27W/cm at tube wall load 2Shi Yuewei 20%, and if be made as 22～25W/cm 2Scope, then be reduced to below 10%.
As shown in Figure 9, the luminous flux sustainment rate reduces when tube wall load becomes big.If tube wall load is at 22～25W/cm 2Scope in, the luminous flux sustainment rate of then lighting after 12000 hours is 75～85%, when tube wall load reaches 30W/cm 2The time, then the luminous flux sustainment rate just is reduced to 60～80%, and fluctuation increases.That is, if tube wall load at 22～25W/cm 2Scope in, luminous flux sustainment rate height then, and fluctuation is few.
Among the described embodiment, the test of using high-pressure mercury-vapor lamp to use is tested with stabilizer.But the stabilizer that commercially available high-pressure mercury-vapor lamp is used has and this test identical characteristic of stabilizer.So,, obviously also can obtain the effect identical with described embodiment even possessed the metal halide lamp of described embodiment and the ligthing paraphernalia of the stabilizer that high-pressure mercury-vapor lamp is used.
