Description
Technical field
The present invention relates to long arc type metal halide lamp, in luminous tube, be particularly sealed with the long arc type metal halide lamp of the metal such as mercury, iron and halogen.
Background technology
In the past, the long arc type metal halide lamp being sealed with mercury, other metals and halogen in luminous tube is widely used in the purposes of the sclerosis of such as resin, binding agent, ink, photoresist, drying, melting or the various process such as softening as the ultraviolet lamp of radiation.Specifically, to shone thing (workpiece) irradiation ultraviolet radiation being coated with binding agent etc., there is chemical reaction to process by making it.JP 2008-311119 publication (patent documentation 1) etc. discloses this structure.
Fig. 4 discloses the conventional example of this long arc type metal halide lamp.Fig. 4 (A) is the cutaway view of lamp entirety, and Fig. 4 (B) is the amplification view of its sealing part.
As shown in Figure 4, long arc type metal halide lamp has the luminous tube 1 be made up of with the sealing part 3 of its front end illuminating part 2, between above-mentioned illuminating part 2 and sealing part 3, is provided with the reducing diameter part 4 from this illuminating part 2 towards sealing part 3 reduced diameter.
In above-mentioned illuminating part 2, be sealed with mercury, other metal, halogen etc., and electrode stacks 5,5 is oppositely disposed.
Further, in above-mentioned sealing part 3, in the mode covering this sealing part 3 and above-mentioned reducing diameter part 4, cylindric pedestal 6 is installed by binding agent 7 grade.
But, in recent years, reduce the requirement grow of these long arc type metal halide lamp to carrying capacity of environment, wish the use power reducing lamp.
From this background, in order to reduce use power, studying the ignition method switching continually and drop into power and use.
Such as, exist when irradiating workpiece with power lighting during normal lighting, being reduced to the power lower than it when carrying workpiece and waiting for machine, again carrying the ignition method (hereinafter referred to as full load/standby (full-standby) lighting) of high-power switching lighting power when needing irradiation.
On the other hand, from environmental problem, also requiring the use amount of restriction mercury, in order to tackle this requirement, following problem can be produced for the Metal halogen lamp reducing amount of mercury when power switched carries out lighting continually as mentioned above.
When carrying out full load/standby lighting, being 60 DEG C when normal lighting (full load lighting) near the sealing part of luminous tube, is 400 DEG C when standby lighting (standby lighting).
In the inside of luminous tube, from two ends sealing part more close to, distance electric arc is far away, and can blow to cooling air, and therefore temperature is minimum.
When normal lighting with during standby lighting with identical condition cool down lamp time, during standby lighting, sealing part is cooled excessively, enclose inner metal condensing from steam, be frozen into liquid or solid, when therefore again returning normal lighting, need to expend time in evaporation of metal.
In the above prior art, as shown in Fig. 4 (B), the radiant light X radiated from the reducing diameter part 4 of luminous tube 2 end is reflected by the inwall of pedestal 6, rearward radiate, the heating of tube ends can't be contributed to, in any case the solidifying of the inclosure metal at this position, condensingly all cannot to avoid.

Summary of the invention
The present invention makes in view of above problem, a kind of long arc type metal halide lamp is provided, it has the luminous tube having the illuminating part of pair of electrodes to form with the sealing part at the two ends being arranged on this illuminating part by relative configuration, reducing diameter part is provided with between above-mentioned illuminating part and sealing part, there is the cylindric pedestal at least covering this reducing diameter part, can not produce in reducing diameter part due to cooling air during standby lighting in full load/standby lighting and enclose the problem that metal is condensing or solidify.
In order to solve the problem, the feature of long arc type metal halide lamp of the present invention is, it is concentric cylindrical portion that above-mentioned reducing diameter part has with above-mentioned cylindric pedestal.
In addition, it is characterized in that, the total of the length of the cylindrical portion of this reducing diameter part of above-mentioned reducing diameter part on the tube axial direction of lamp is greater than the total of the length of the part beyond the cylindrical portion of this reducing diameter part.
According to the present invention, it is concentric cylindrical portion that reducing diameter part is formed with cylindric pedestal, the heat of being radiated by this reducing diameter part is thus reflected by pedestal and again returns reducing diameter part, and this reducing diameter part is heated thus, therefore, it is possible to it is condensing or solidify therein to prevent enclosing metal.

Fig. 2 is the amplification view of the neighbouring part of sealing part of Fig. 1.
Fig. 3 is the table representing effect of the present invention.
Fig. 4 is the cutaway view of prior art, and (A) is overall cutaway view, and (B) is phantom.
Embodiment
Fig. 1 represents the overall diagram of long arc type metal halide lamp of the present invention, and Fig. 2 represents the enlarged drawing of its reducing diameter part part.
Long arc type metal halide lamp has the luminous tube 1 be made up of with the sealing part 3,3 at its two ends illuminating part 2, to sealing part 3, be formed with reducing diameter part 10 from illuminating part 2, this reducing diameter part 10 be formed and surround its cylindric pedestal 6 in concentric multiple cylindrical portion 11a, 11b.
The total of the length of the tube axial direction of above-mentioned cylindrical portion 11a, 11b is formed as longer than the total of the i.e. length of non-cylindrical portion 12a, 12b, 12c in addition.
By forming said structure, as shown in Figure 2, the radiant light Y radiated from the cylindrical portion 11 of reducing diameter part 10 is vertical relative to tubular axis, therefore at right angles to irradiates relative to the inwall of pedestal 6, and its reverberation Z is also reflected by perpendicular to tubular axis, returns reducing diameter part 11.
Thus, is heated by this reverberation near the reducing diameter part of illuminating part 2 10, eliminated the problem that inclosure metal in illuminating part 2 is condensing.
Carried out the experiment of checking effect of the present invention, its result is as shown in the table of Fig. 3.
First, the luminous tube external diameter of testing the long arc type metal halide lamp used is φ 26mm, length of illumination is 1100mm, rated power is 18kW, and lamp input power is 160W/cm, enclosure is: mercury is sealed with 1.0 μm of ol/cc, iron is sealed with 0.2 μm of ol/cc, iodine is sealed with 0.4 μm of ol/cc, xenon and is sealed with 50torr.
The reducing diameter part being produced on this lamp is formed with the lamp of the present invention of Fig. 1, Fig. 2 of cylindrical portion and does not arrange cylindrical portion and be formed as the existing lamp shown in Fig. 4 of R shape, and the measuring point at three places shown in Fig. 1 carries out the mensuration of temperature.That is, junction surface (C) (shoulder temperature) this 3 point of the central portion (A) (illuminating part temperature) of illuminating part, positive upper end (B) (end region temperature) of electrode front end, sealing part and illuminating part is measured.
Its result as shown in Figure 3, confirms, in lamp of the present invention, end region temperature is higher than the temperature of the same area of existing lamp 70 DEG C, improves heat-insulating property.
Further, this end region temperature (923 DEG C), higher than illuminating part temperature (860 DEG C), confirms and can prevent metal halide from invading to this part.
As described above, in long arc type metal halide lamp of the present invention, it is concentric cylindrical portion that reducing diameter part between the illuminating part and sealing part of luminous tube is formed with cylindric pedestal, therefore the radiant light from this reducing diameter part is reflected by pedestal and again returns reducing diameter part, this part is incubated, therefore, it is possible to prevent the metallic vapour enclosed in luminous tube from invading this part, it can be prevented the solidifying of this position, condensing.
Therefore, enclose metal all evaporate and for luminescence, the luminescence of hope can be obtained.
