Description

本発明は、耐候光試験用ランプに関する。   The present invention relates to a weatherproof lamp.

従来、耐候光試験用ランプとしては、カーボン電極では、セリウムをコアとしたセリウムコアカーボン電極(サンシャインカーボン電極)や、紫外線カーボン電極が耐候試験用に用いられていた(例えば、特許文献1参照)。
実開昭58−152768号公報(第1頁第1欄)
Conventionally, as a lamp for weathering test, a cerium core carbon electrode (sunshine carbon electrode) having cerium as a core or an ultraviolet carbon electrode has been used for a weathering test as a carbon electrode (see, for example, Patent Document 1). .
Japanese Utility Model Publication No. 58-152768 (page 1, column 1)

カーボン電極では、カーボンの特徴である380〜390nm付近のシアンバンドと350nm付近の著しいピークがある。サンシャインカーボン電極では、セリウムの存在に可視域でも分光エネルギーがやや高い波長域帯を有する。カーボン電極は、太陽エネルギーに近似した光源として使用されている。太陽エネルギーに近似した光源として使用されているランプとしては、他にキセノンランプ等もあるが、使用時間によって各波長における分光エネルギーが低下する。一方、カーボン電極では、使用時間によって各波長における分光エネルギーが低下することがない。   The carbon electrode has a cyan band around 380 to 390 nm and a remarkable peak around 350 nm, which are characteristic of carbon. In the sunshine carbon electrode, the presence of cerium has a wavelength band with slightly higher spectral energy even in the visible range. The carbon electrode is used as a light source that approximates solar energy. Other lamps used as a light source that approximates solar energy include a xenon lamp, but the spectral energy at each wavelength decreases with the use time. On the other hand, in the carbon electrode, the spectral energy at each wavelength does not decrease depending on the use time.

しかし、従来のカーボン電極の耐候光試験用ランプにおいては、400nm以上の波長域の分光エネルギー量が紫外線部に比べ低かった。したがって、500nmを中心とした可視域の光エネルギー量により劣化度合いが著しく変わる材料については、必ずしも適切な結果を得ることができないという問題があった。   However, in a conventional carbon electrode weatherproof test lamp, the spectral energy amount in the wavelength region of 400 nm or more was lower than that in the ultraviolet part. Therefore, there has been a problem that an appropriate result cannot always be obtained for a material whose degree of deterioration changes significantly depending on the amount of light energy in the visible region centered on 500 nm.

本発明が解決しようとする問題点は、材料の性質によっては500nmを中心とした可視域のエネルギーを含む太陽光による劣化と結果が乖離するおそれがある点である。   The problem to be solved by the present invention is that depending on the properties of the material, there is a risk that the result may be different from the deterioration due to sunlight including energy in the visible region centered on 500 nm.

本発明は、かかる問題を鑑みてなされたものであり、したがって、本発明の目的は、500nmを中心とした可視域のエネルギーを含む太陽光による劣化と耐候光性試験の結果との乖離を低減できる耐候光試験用ランプを提供することにある。本発明者らは、上記の目的を達成するために鋭意研究を重ねた結果、試行錯誤の上、本発明を完成するに至った。   The present invention has been made in view of such a problem. Therefore, the object of the present invention is to reduce the difference between the deterioration due to sunlight including energy in the visible range centered on 500 nm and the result of the weather resistance test. An object of the present invention is to provide a lamp for weathering test. As a result of intensive studies to achieve the above object, the present inventors have completed the present invention through trial and error.

上記目的を達成するために、本発明の耐候光試験用ランプは、カーボン電極に、発光体としてツリウム化合物を添加することを特徴とするものである。   In order to achieve the above object, the weather-resistant test lamp of the present invention is characterized in that a thulium compound is added as a light emitter to a carbon electrode.

また、本発明の耐候光試験用ランプは、石英管に、発光体としてツリウム化合物、及び始動ガスとして水銀を封入したことを特徴とするものである。   In addition, the weathering light test lamp of the present invention is characterized in that a quartz tube is filled with a thulium compound as a light emitter and mercury as a starting gas.

また、本発明の耐候光試験用ランプは、前記ツリウム化合物が、ツリウムのハロゲン化物又は酸化物であることを特徴とするものである。   In the weathering light test lamp of the present invention, the thulium compound is a thulium halide or oxide.

また、本発明の耐候光試験用ランプは、ランプから試料に照射される光が、500nmを中心としたスペクトルピークを有し、太陽光に近似した分光分布を有することを特徴とするものである。   In addition, the weathering light test lamp of the present invention is characterized in that the light emitted from the lamp to the sample has a spectral peak centered at 500 nm and has a spectral distribution approximate to sunlight. .

また、本発明の耐候光試験用ランプは、さらに、赤外部遮断フィルタを組み合わせることを特徴とするものである。   In addition, the weathering light test lamp of the present invention is further characterized by combining an infrared part cut-off filter.

また、本発明の耐候光試験用ランプは、さらに、紫外部遮断フィルタを組み合わせることにより、太陽光には存在しない紫外部のエネルギーを遮断したことを特徴とするものである。   Further, the weatherproof light test lamp of the present invention is characterized in that the ultraviolet energy which does not exist in sunlight is blocked by combining an ultraviolet blocking filter.

本発明の耐候光試験用ランプは、上述したとおりであるので、500nmを中心とした分光分布を有する太陽光に、より近い分光エネルギーを有し、したがって、500nmを中心とした可視域のエネルギーを含む太陽光による劣化と耐候光性試験の結果との乖離を低減できる。   Since the lamp for weathering test according to the present invention is as described above, it has a spectral energy closer to that of sunlight having a spectral distribution centered on 500 nm, and therefore has a visible energy centered on 500 nm. It is possible to reduce the difference between the deterioration caused by sunlight and the results of the weather resistance test.

本発明の最良の実施例について、以下に図を用いて詳細に述べる。   The best embodiment of the present invention will be described in detail below with reference to the drawings.

本発明の実施例1の耐候光試験用ランプは、ツリウムのハロゲン化物を添加したカーボン電極である。本発明の実施例1の耐候光試験用ランプでは、ツリウムのハロゲン化物をカーボン電極の芯材として添加した。ツリウムのハロゲン化物は、発光体としての役割を果たす。本発明の実施例1の耐候光試験用ランプのカーボン電極の芯材は、安定剤及び結合材に、ツリウムのハロゲン化物を添加したものである。本発明の実施例1の耐候光試験用ランプでは、ヨウ化ツリウムを用いる。カーボン電極は、カーボンを1150℃で焼成し、芯材は、温度850℃で焼成して作製した。例えば、135V16Aの条件で点灯させる。本発明の実施例1の耐候光試験用ランプは、400nm〜800nmの範囲でブロードなスペクトルピークを有し、太陽光に近似した分光分布を有する。カーボン電極では、キセノンランプ等と異なり、使用時間によって各波長における分光エネルギーが低下することがない。   The lamp for weathering test of Example 1 of the present invention is a carbon electrode to which a thulium halide is added. In the weathering light test lamp of Example 1 of the present invention, thulium halide was added as a core material of the carbon electrode. The thulium halide serves as a light emitter. The core material of the carbon electrode of the lamp for weathering test of Example 1 of the present invention is obtained by adding a thulium halide to a stabilizer and a binder. In the lamp for weather resistance test of Example 1 of the present invention, thulium iodide is used. The carbon electrode was produced by firing carbon at 1150 ° C., and the core material was fired at a temperature of 850 ° C. For example, the lighting is performed under the condition of 135V16A. The lamp for weathering light test of Example 1 of the present invention has a broad spectrum peak in the range of 400 nm to 800 nm, and has a spectral distribution approximate to sunlight. In the carbon electrode, unlike a xenon lamp or the like, the spectral energy at each wavelength does not decrease with the use time.

Deviation between the deterioration due to sunlight and the results of the weather resistance test can be reduced. Because of the synergistic effect of the spectral distribution of carbon and thulium, the weather light test lamp of Example 1 of the present invention is superior to the conventional weather light test lamp because it has a spectral energy similar to sunlight.

In the weathering light test lamp of Example 3 of the present invention, thulium iodide is used. FIG. 2 is a spectral distribution diagram of Example 3 of the weathering test lamp of the present invention. Other metal compounds are not encapsulated. The weathering light test lamp of Example 3 of the present invention is lit under the condition of 250V14A, for example.
