Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、炬燵（こたつ）などの熱源として使用され
るヒータランプの点灯方法に関するものである。The present invention relates to a method for lighting a heater lamp used as a heat source for a kotatsu or the like.
最近では、赤外線放熱体が加熱や乾燥の分野に広く利
用されつつある。赤外線は、電磁波であって、放射によ

線は、水分によく吸収され、従って人体にもよく吸収さ
れるので、家庭用暖房器具の中でも、とりわけ、炬燵用
の熱源に適している。Recently, infrared radiators have been widely used in the fields of heating and drying. Infrared rays are electromagnetic waves, and heat is transmitted by radiation. Infrared rays having a wavelength of about 3 μm are well absorbed by moisture and therefore well absorbed by the human body. Suitable for heat source for kotatsu.
炬燵用の赤外線放射体としては従来よりシーズヒータ

しながら、シーズヒーターは通電直後の温度の立上りが
極めて遅い不具合がある。また、最高温度もせいぜい40
0℃程度であり、熱効率上も好ましくない。As an infrared radiator for a kotatsu, a sheathed heater that has been conventionally covered with a heat sink having a low emissivity in a short wavelength range and a high emissivity in a long wavelength range has been used. However, the sheathed heater has a problem that the temperature rise immediately after energization is extremely slow. Also, the maximum temperature is at most 40
It is about 0 ° C., which is not preferable in terms of thermal efficiency.

強く放射されるので、炬燵用などの赤外線放熱用ヒータ
ランプとしては極めて好ましい。For this reason, it is conceivable to use an incandescent lamp in which a tungsten filament is arranged along the tube axis of a straight tubular quartz bulb and an inert gas containing halogen is sealed inside. In other words, such an incandescent light bulb has the advantage that the temperature rises immediately after energization is fast and the maximum tube wall temperature is much higher than that of the sheathed heater, so that thermal efficiency is good. When a black ceramic coating film is formed as an infrared radiation film on the outer surface of the quartz bulb, infrared rays are strongly radiated, which is extremely preferable as a heater lamp for infrared radiation such as for a torso.

され、管壁温度を下げるために管壁負荷を小さくし過ぎ

がり速度が減殺されてしまう不具合がある。By the way, in halogen incandescent lamps for general lighting, the tube wall load (power input per valve unit area) is 30
It is often turned on at about W / cm 2 , and the tube wall temperature is 1000 ° C.
As mentioned above, in a heater lamp with a black ceramic coating film, light does not pass through the bulb. Therefore, if the lamp is lit with such a large wall load, the bulb's durability will decrease and the lamp life will be shortened. There is a problem that becomes. In addition, it is preferable that infrared rays emitted from a heater lamp used for a kotatsu or the like have many far-infrared regions having long wavelengths, but the emitted wavelength changes depending on the tube wall temperature. When the temperature is extremely high (1030 ℃) or higher, the peak wavelength tends to the near-infrared region with a short wavelength, and the far-infrared component decreases. On the other hand, on the other hand, the temperature rising speed immediately after the normal is also affected by the tube wall load, and if the tube wall load is made too small in order to lower the tube wall temperature, the fast temperature rising speed, which is a feature of incandescent bulbs, is reduced. There is a problem that will be done.
そこで本発明は、放射される波長は遠赤外領域成分が

ランプの点灯方法を提供することを目的とする。Therefore, the present invention provides a method for lighting a heater lamp, in which the radiated wavelength has many far-infrared components and is suitable for a heat source such as a torso, has high bulb durability, and has a fast temperature rising speed immediately after energization. The purpose is to do.

W/cm2とすることを特徴とする。According to the structure of the present invention, a black ceramic coating film is formed on the outer surface of a straight tubular quartz valve in which a filament is arranged along the tube axis and an inert gas containing halogen is filled inside. A method of lighting a heater lamp using infrared rays mainly radiated from a film, wherein the heater wall load is 6 to 15

り速度を調和させることができる。That is, the present inventor, as a result of intensive investigation of the tube wall load of the heater lamp in a region largely apart from the region of the tube wall load of the conventional incandescent light bulb, the invention has been completed, and the tube wall load is 15 W / cm. If it exceeds 2 , the tube wall temperature will be 1300K or more, the peak of the wavelength will be about 2.3 μm, and it will approach the near-infrared ray with a short wavelength, and the far-infrared ray component will decrease. Further, since the heater lamp does not allow light to pass through the bulb, the durability of the bulb is extremely lowered at this temperature. Conversely, the wall load
In 5W / cm 2, it takes about 90 seconds to warm to a temperature of 900K valve surface is slightly red, about 60 seconds for 6W / cm 2, the temperature within one minute at 6W / cm 2 or more Warm up and take advantage of the fast rising speed. That is, by setting the tube wall load of the heater lamp to 6 to 15 W / cm 2 , it is possible to harmonize the radiated wavelength range, the durability of the bulb, and the temperature rising speed immediately after energization.

乾燥して焼成すれば形成することができる。The heater lamp shown in FIG. 1 is a halogen bulb having a rated voltage of 100 V. The bulb 1 is made of a straight tubular quartz glass having a length of 170 mm, and has pressure-sealing portions 11 formed at both ends. Then, the molybdenum foil 2 is embedded in the compression-sealing portion 11. A filament 3 in which a tungsten element wire is wound in a coil shape is arranged along the axis of the valve 1. The ends of the inner conductive wire 31 extending from both ends of the filament 3 are welded to the molybdenum foil 2, and one end of the lead 4 is also welded. It is welded to the molybdenum foil 2 and protrudes airtightly from the crimp sealing portion 11 to the outside. The inside of the bulb 1 is filled with an inert gas containing halogen, and a black ceramic coating film 5 having a high infrared emissivity is formed on the outer surface. The ceramic coating film 5 is, for example, a black ceramic thin film having a composition of 53% silica, 5% alumina, 19% phosphoric acid, and 23% copper chromate and having a thickness of about 200 μm. Apply the aqueous solution to the outer surface of the valve 1 by dipping or the like,
It can be formed by drying and firing.

体を温めるので、暖房効果の優れた炬燵になる。Then, when the heater lamp of such a configuration is energized,
The temperature of the bulb 1 rises and the ceramic coating film 5 is heated to emit infrared rays. Here, since the radiated wavelength is influenced by the tube wall temperature, and the tube wall temperature has a close relationship with the tube wall load, these relationships were investigated. The result is
Shown in the figure. As can be seen from this, when the tube wall load increases, the tube wall temperature rises, but when the tube wall load reaches 16 W / cm 2 , the tube wall temperature becomes 1300 K or higher, and the ceramic coating film 5 is formed on the outer surface, so that light is emitted. Since it does not transmit, the durability of bulb 1 is extremely reduced, but the peak wavelength is 2.5μ.
m and the far infrared component decreases. On the other hand, if the wall load is 15 W / cm 2 or less, the wall temperature will be 1300 K.
And the durability of the valve 1 is sufficient,
It emits infrared light having a peak wavelength of about 2.5 to 3 μm. This infrared ray has many far infrared rays components and is well absorbed by the human body. Therefore, when used as a heat source for a kotatsu, it effectively warms the human body, resulting in a kotatsu having an excellent heating effect.
一方、管壁負荷を小さくし過ぎると、通電直後の温度

温し、立ち上がり速度が早いメリットが生かされること
が判明した。On the other hand, if the tube wall load is made too small, the rising speed of the temperature immediately after energization will be slowed down, and the features of the incandescent bulb will be diminished. The relationship of wall load was investigated. As a result, it takes about 90 seconds when the wall load is 5 W / cm 2 , but 6 W / c
At m 2 , it took about 60 seconds. At 6 W / cm 2 or more, it was found that the temperature was raised within one minute, and that the advantage of a fast rise speed was utilized.
結局のところ、ヒータランプの管壁負荷を６〜15W/cm

If it is set to 2 , the emitted wavelength has many far-infrared components, and the durability of the bulb and the rising speed of the temperature immediately after energization can be sufficiently satisfied.

Since it emits light in the cm 2 range, the emitted wavelength has a lot of far-infrared component and is suitable for a heat source such as a torso, the durability of the bulb is not deteriorated, and the advantage that the temperature rising speed immediately after energization is fast is utilized. be able to.
