従来の色度測定装置は、リフレックスリフレクターａの色度測定の場合は、図 ２のように、投光器ｂから照射された光ｃをリフレックスリフレクターａに照射 し、その反射光ｄを直接色度計ｅにより色度値を測定している。 When measuring the chromaticity of a reflex reflector a, the conventional chromaticity measuring device As shown in 2, the light c emitted from the floodlight b is irradiated onto the reflex reflector a. The chromaticity value of the reflected light d is directly measured using a chromaticity meter e.

しかし、前記従来の技術では、次のような問題点がある。 However, the conventional technology has the following problems.
【０００５】 イ．リフレックスリフレクターを測定する場合は、投光器ｂから照射された光 ｃによる反射光ｄを直接測定するため、反射光の色のみでなく、リフレックスリ フレクター自体の表面の色も測定している場合があるため、測定値の誤差発生の もととなっている。[0005] stomach. When measuring a reflex reflector, use the light emitted from projector b. Since the reflected light d by c is directly measured, not only the color of the reflected light but also the reflex In some cases, the color of the surface of the reflector itself is also measured, so there may be errors in the measured values. It is the basis.
【０００６】 ロ．リフレックスリフレクターとランプのそれぞれの測定の場合は、各設備を 配置換えしないと測定できない。[0006] B. ReflexFor measurements of reflectors and lamps, each equipment must be Measurement is not possible without rearrangement.
【０００７】 ハ．色度測定装置に使用される設備は、配光試験設備を流用しているため、同 時に、色度測定と配光試験ができない。[0007] C. The equipment used for the color measurement device is the same as the light distribution test equipment. Sometimes chromaticity measurements and light distribution tests are not possible.
【０００８】 ニ．装置同士が大きいため、投光器と色度計の距離が５ｍ以上必要であり、装 置配置の角度θを小さくすることが難しい。[0008] D. Because the devices are large, the distance between the projector and colorimeter must be at least 5 m, making it difficult to install. It is difficult to reduce the angle θ of placement.
【０００９】 そこで、本考案は、上記従来の技術の問題点に鑑みて創案されたもので、リフ レックスリフレクターとランプの色度測定に同一装置で共用可能な色度測定装置 の提供を目的としている。[0009] Therefore, the present invention was devised in view of the problems of the above-mentioned conventional technology. A color measurement device that can be used in common for measuring the chromaticity of Rex reflectors and lamps. The purpose is to provide
