Definitions
- the invention relates to a high-pressure mercury vapour discharge lamp having a given power consumption during operation, provided with a discharge vessel having a wall of gas-tight, radiation transmitting ceramic material, said discharge vessel enveloping a discharge space and being provided with an ionizable filling comprising a rare gas, mercury, sodium halide and thallium halide, an electrode being disposed within said discharge vessel in the proximity of each of two end wall parts, the electrode tips facing each other being located at a mutual distance EA.
- a lamp of this type is known, for example, from United States Patent Specification 3,363,133 showing a discharge vessel of ceramic material, namely densely sintered polycrystalline aluminium oxide.
- the known lamp comprises one or more metals such as thallium and furthermore it may comprise an alkali metal, for example, sodium.
- metal halides in most cases metal iodides, to the ionisable filling of a high-pressure mercury vapour discharge lamp is a step that has been used for quite some time in lamps having a quartz glass discharge vessel. Its object is to obtain a higher density of metal atom- in the discharge space by utilizing the greater volatility of the metal halides as compared with that of the metals themselves, and hence a greater contribution of the metals to the radiation emitted by the lamp. This results in an improvement of the relative luminous flux and Malawiularly also the colour rendition of the lamp. Alkali metals such as sodium and lithium are used in a halide form because these metals themselves are too aggressive relative to the quartz glass wall of the discharge vessel.
- the halide pressure is determined by the temperature of the coldest spot T k p within the discharge vessel.
- the maximum admissible value of T k p is limited by the material of the discharge vessel. In the case of quartz glass discharge vessels T k p may not be more than approximately 800°C. It has already been recognized at an early stage that the use of materials for the wall of the discharge vessel which can be subjected to a higher thermal load may lead to higher halide pressures. United States Patent Specification 3,234,421 already states the possibility (fusing densely sintered aluminium oxide as a material for the discharge vessel.
- United States Patent Specification 3,334,261 mentions lamp fillings comprising halides of rare earth metals. It has been found that lamps having a satisfactory colour rendition are possible particularly with Dy, Ho, Er, Tm and/or La. A drawback of these lamps is that they have a high colour temperature (4000 K or higher). For practical uses a lower colour temperature is often very much desired. If the colour temperature in these lamps is to be decreased, the use of sodium halide is generally required which must be used in comparatively large quantities. This results in a great decrease of the contribution of the rare earth metals to the radiation emitted by the lamp so that the colour rendition of the lamp is adversely affected.
- a lamp of the type described in the opening paragraph is characterized in that the wall load, defined as the quotient of power consumption and outer surface area of the part of the wall of the discharge vessel located between the electrode tips, has a value of at least 25 W/cm 2 , in that the ratio between the effective internal diameter ID of the discharge vessel and EA has a value in the range of 0.4 ⁇ ID/EA ⁇ 0.9, ID being defined as the square root of the quotient of the volume of the discharge space between the electrode tips and EA, and in that the ratio between the largest internal diameter ⁇ i of the discharge vessel and EA is at most equal to 1.1.
- the invention is based on the recognition of the fact that a satisfactory colour rendition is possible when sodium halide is used in the filling of a lamp if during operation of the lamp there is a strong broadening and reversal of the emission of the sodium in the Na-D lines which are located at 589.0 and 589.6 nm at very low partial Na-pressures.
- broadening and reversal the Na-D lines assume the shape of emission bands, the short-wave band being shifted to shorter wavelengths and the long-wave band being shifted to longer wavelengths as the emission is more reversed.
- a measure of the reversal is therefore the distance in nm between the maximum values of the Na-emission bands.
- T k p are attained in a lamp according to the invention by dimensioning the discharge vessel for a given power consumption during operation in such a manner that the wall load has a value of at least 25 W/cm .
- the wall load is defined as the quotient of power consumption and surface area of the discharge vessel, considering only that part of the outer surface area of the discharge vessel that is located between the electrode tips.
- the second condition which is to be fulfilled to obtain a sufficiently high ⁇ is that the actual discharge arc in the discharge vessel is to be surrounded with a sufficiently thick layer of Na-atoms in the fundamental state.
- the discharge vessel must fulfil given geometrical requirements, notably a relatively wide discharge vessel is necessary.
- ID is herein understood to mean the square root of the quotient of the volume of the discharge space between the electrode tips and EA.
- the distance between the electrode tips and the adjacent end wall parts of the discharge vessel is not more than half the largest internal diameter (1 ⁇ 2 ⁇ i ). In that case the required high value of the temperature of the coldest spot in the lamp can more easily be attained, generally also without extra steps for heat insulation of the lamp extremities.
- the lamps according to the invention have the advantage that for a given filling they have only a little spread in the colour point of the emitted radiation and also a very small variation of the colour point during their lifetime.
- a great advantage of these lamps is that they do not substantially show any colour variation when varying the supplied power within fairly ample limits. It has been found that the effects of variations in the power counteract each other, in a sense, as a result of the relatively high sodium pressure and the lamp geometry used, so that a colour point stabilisation is obtained.
- the mercury quantity is mainly determined by the arc voltage desired in the lamp.
- the mercury quantity will frequently be relatively low for lamps having a high power (for example at least 1 mg per cm 3 of the discharge space at powers of the order of 2000 W) and will increase with a decreasing power (to, for example 100 mg per cm 3 at powers of the order of 10 W).
- the filling of the lamps according to the invention comprises halides, preferably iodides, of sodium and of thallium.
- the sodium halide is present in excess, that is to say, unevaporated sodium halide is still present during operation of the lamp.
- the sodium halide quantity is generally at least 10 / u mol per cm 3 of the discharge space (for lamps having a higher power) and assumes larger values as the power decreases (for example, to 500 / umol per cm 3 for the smallest lamps).
- the thallium halide contributes in the form of the predominantly green thallium radiation so that white or substantially white light can be obtained in combination with the sodium radiation.
- Lamps are preferred which are characterized in that the molar ratio between thallium halide and sodium halide is at least 0.05 and at most 0.25.
- the lamps according to this preferred embodiment emit light at a comparatively low colour temperature, which is very much desirable for certain uses (for example, lighting for the living room and decorative lighting).
- the colour temperature is dependent on the Tl:Na ratio chosen and has values of approximately 2500 K (colour point slightly below the line of the black radiators and having a slightly yellow colour aspect) to approximately 3000 K (colour point slightly above the line of the black radiators and having a slightly green colour aspect).
- Lamps having a colour point which is substantially on the line of the black radiators have a colour temperature of approximately 2700 K.
- a further advantageous embodiment of a lamp according to the invention is characterized in that the discharge vessel further comprises at least one halide of a metal radiating substantially in the blue or purple part of the spectrum, which halide, compared with sodium halide, has a high volatility and in which the molar ratio between this halide and the halides of Na and Tl combined has a value of up to 0.1 at a maximum.
- the use of blue or purple radiators provides the possibility of obtaining lamps having a higher colour temperature of the emitted radiation (higher than approximately 2700 K). To maintain satisfactory colour rendition properties, it is required for the halide of the blue or purple radiator to be used in relatively small quantities because otherwise the sodium halide is too much diluted so that A A would be adversely affected.
- volatile halides are chosen (saturated vapour pressure at 900°C at least a factor of 10 larger than that of sodium iodide) in which the molar ratio between these halides and the halide of Na and Tl combined is not more than 0.1 and preferably of the order of 0.01. In this manner lamps can be obtained having a high efficiency, a satisfactory colour rendition and a colour temperature of up to approximately 3200 K. Lamps of this type are preferred which comprise at least one halide of at least one of the elements In, Sn and Cd because the best results are achieved with these halides.
- a further preferred embodiment of a lamp according to the invention is characterized in that the discharge vessel also comprises at least one halide of at least one of the elements Sc, La and the lanthanides, in which the molar ratio between these halides and the halides of Na and Tl combined has a value of at least 0.02.
- the said elements Sc, La and the lanthanides have an emission consisting of many lines distributed over the entire spectrum with the centre generally being in the blue part of the spectrum so that these elements, if used only in a lamp, yield a colour point of the emitted radiation of b 5000 K. Consequently, with the lamps of this embodiment as compared with the lamps comprising only Na and Tl higher colour temperatures can be attained whilst maintaining high luminous fluxes and very satisfactory colour rendition properties.
- Values of the molar ratio between the halides of Sc, La and/or lanthanide and the halides of Na and Tl combined are then chosen to be at least 0.02 because then generally colour temperatures are attained of at least 3000 K. In fact, for colour temperatures of less than 3000 K the embodiments described hereinbefore with volatile, blue radiators are found to be more advantageous. In these lamps having a colour temperature of 3000 K or more the use of at least one halide of at least of one of the elements Dy, Tm, Ho Er and La is preferred. With Dy lamps can be obtained having very high values of Ra8 and R 9 and with colour temperatures of up to approximately 3600 K.
- the molar ratio between dysprosium halide and sodium and thallium halide is then preferably 0.03 or more.
- Tm, Ho, Er and La it is possible to make lamps having colour temperatures of up to approximately 4500 K, where the molar ratio between the halides of these lanthanides and the sodium and thallium halide is preferably chosen to be 0.04 or more.
