Abstract
Electric infrared lamp of the present invention has tubular glass bulb container (1), and this container seals with the vacuum seal method, and tungsten filament (4) wherein is set, this filament winding spirality, and its each circle (5) engages with the tube wall of bulb container (1).Duration of work, the temperature of filament (4) remain between about 1200 ℃ to about 1500 ℃.
Description
The present invention relates to a kind of infrared bulb, it comprises:
-one with vacuum seal method sealing and by containing 95%(at least by weight) SiO
2The tubular bulb container that constitutes of glass,
The tungsten filament of-one coiling in this bulb container, each circle of this filament engages with the tube wall of described bulb container,
-extend to each outside power supply stream electrode from this filament.
Germany patent 1,069,794B discloses a kind of like this infrared bulb.
The purpose of this known bulb is: with compare in the situation of each supporter that distributes on the filament (each supporter spirals the tube wall of bulb container so that on the filament centre-lock from filament), in whole filament length scope, obtain infrared more uniformly (IR) radiation output.In the zone with this supporter, each circle is short circuit, has therefore reduced the heat that wherein produces, and each supporter is dissipated to heat on the tube wall of bulb container from filament simultaneously.
In this known bulb, some circle of filament (they are distributed in the whole filament scope) has non-garden shape, for example leg-of-mutton or oval shape, these circles have such size, promptly, some part of these circles is engaged with the tube wall of bulb container, thereby each circle of all the other (garden shapes) of this filament is fixed on the center of this bulb container.
Such filament can only be made originally with very high one-tenth.
The very big shortcoming of common infrared bulb (wherein with supporter filament being fixed on the center of bulb container) is: they produce quite a large amount of luminous raies (4 to 5 lm/W).For 1000W and 1500W(for, for example be used for the infrared radiator of room heating, this is very usual power) infrared bulb, this means the luminous flux of 4500lm and 6750lm respectively.This luminous flux is equivalent to the luminous flux that 375W and 563W glass bulb (GLSlamp) may be launched respectively.This luminous flux is high really, because need the high power that dissipates in a smaller bulb, that is, the dissipation power density in tube wall surface zone approximately is 20W/cm
2
When infrared radiator is used for, for example heating in balcony, dais, church etc. and when in stock breeding, being used for the animal house heating, high like this luminous flux is stinking.Therefore, all use the quartz glass tube of redness to surround during common this class bulb work.But this quartz glass tube makes this bulb become very expensive, and makes the radiation efficiency of this infrared bulb reduce about 18%.
A shortcoming of common bulb is its red-emitting.Another shortcoming is: because described red quartz glass tubes, therefore the diameter of bulb that has shell, when this bulb is used for reflector, will use darker bigger reflector, so that the radiation convergence greater than the diameter of uncanned bulb.
The object of the present invention is to provide out the bulb of type described in the TOUYIJIE, this bulb has very simple structure and the output of low-down visible light, and the long-pending high power that still can dissipate of per unit tube wall surface.
According to the present invention, in the bulb of opening the described type of TOUYIJIE, reached this purpose, this is the spirality coiling because of: described filament, and each circle engages with the tube wall of bulb container, and because: duration of work, the temperature of described filament remain between about 1200 ℃ to about 1500 ℃.
These intrinsic characteristics make it possible to reach at purpose, and provide a kind of very long-life bulb that has.Because this filament presents the low temperature state when working under design voltage, thus this filament can be under without any the situation of defective with by, for example the tube wall of the bulb container made of quartz glass engages.Therefore, and must compare the situation that filament be fixed in the middle of the bulb container coaxially, described each circle has significantly bigger diameter.This of each circle can hold longer tungsten filament with comparable the allowing than major diameter of the internal diameter of bulb container in this filament, thereby realized lower working temperature.
When the temperature of filament during far below 1200 ℃, owing to increased the weight of filament, so the cost of bulb has improved significantly.In addition, bulb reaches the needed time of working temperature and has also extended significantly after the energising.
When temperature surpassed 1500 ℃ significantly, the glass of bulb container was with overheated.
In most preferred embodiment, bulb container has such stuffing pressure, that is, duration of work, blanketing gas have the pressure of the highest about 1 crust.Therefore, avoided the bulb container that causes by some reason break or other situations cause the bulb blast, if this bulb is operated in the unlimited light source, blast will cause the fragment of bulb container to be gone out.For this reason, this bulb preferably is filled into the pressure of about 0.25 to 0.45 crust.
According to one of bulb of the present invention very useful characteristic is the very simple of its structure, so this bulb is very easy to make.
This bulb has the low-down visible light output less than 1lm/W, for example can be 0.1 or 0.5lm/w, and this depends on the temperature of filament.When visible light output 0.5lm/w, it is the same that the glass bulb (GLS lamp) of the amount of visible light of this lamps emission of a 1000W and about 50W is launched.Another advantage is: lamps emission of the present invention is than relatively large long-wave infrared, and it can deeper penetrate for example people's skin, therefore can be used for heating more satisfactorily.
At above-mentioned Deutsche Bundespatent 1,069, to mention among the 794B, it is useful that filament does not contact bulb container.Therefore, have too many and contact point bulb container according to the filament (its every circle all has ellipse garden, leg-of-mutton or tetragonal cross section) of this patent specification.The contact-making surface of filament and bulb container is big more, then also must be big more to the heat that this bulb container conducted from this filament.But the bulb container temperature rises to make and is right after its ambient air heating.Thereby the radiation efficiency of this infrared bulb has reduced.
Experiment proves beyond expectationly: the radiation efficiency that is equivalent to the common infrared bulb that surrounds with red quartz glass tubes according to the radiation efficiency of bulb of the present invention.But, if use bulb of the present invention then obtained this efficient with remarkable low bulb cost; Simultaneously, because the temperature of filament is low, so this bulb has several thousand hours very long life-span.In addition, a kind of suitable, flaxen visible light of lamps emission of the present invention.
Compare with bulb of the present invention, the heat radiator of the helix of the bright dew that is made of chromium/nickel or chromium/nickel/iron/aluminium has very short comparatively speaking about 1000 hours life-span under the situation of the low energy loss of about 1000 ℃ low-down temperature and per unit surface area.
An embodiment of bulb of the present invention is shown in the drawings with the form of end view.
Among the figure, the tubular bulb container 1 of described bulb is by containing 95%(at least by weight) SiO
2Glass, for example quartz glass is made.Bulb container 1 seals by constriction 2 and the vacuum-packed method of 3 usefulness at its two ends.The tungsten filament 4 of coiling is set in bulb container 1.The state that each circle maintenance of filament 4 engages with bulb container 1.Power supply current conductor 6,7 extends to the outside of bulb container 1 from filament 4.
In bulb of the present invention, filament 4 turns to spirality (being double-helical form in the accompanying drawings), and each circle 5 of filament 4 engages with the tube wall of bulb container 1.Duration of work, the temperature of filament 4 remain between about 1200 ℃ to about 1500 ℃.
In one embodiment, when under 220 volts of voltages, working, 1000 watts of power of this bulb consumption.Duration of work, filament have 1300 ℃ temperature.The power loss of luminous tube wall surface is 20W/cm
2This bulb fills to contain 0.2%(by volume) CH
3The argon gas of I, and at room temperature have 0.36 pressure that clings to.The visible light output of this bulb is 0.38lm/W.
