The invention discloses a color selector illuminating system. The color selector illuminating
system comprises light sources, glass, a
light source control touch screen and background plates, wherein the glass is used for separating the light sources and the background plates from materials; the light sources are coaxial light sources; an
edge filter is arranged on the periphery of each coaxial
light source; an electronic
thermostat is arranged under the coaxial light sources; a layer of antireflection film is coated to the surface of the glass; and a layer of high-reflective film is coated to the surface of each background plate. The color selector illuminating
system disclosed by the invention has the advantages that the semi-annular coaxial light sources are designed, so that the color rendering property and the
light reflection strength are improved, and the uniform illuminating can be realized; unwanted
radiation is removed, so that the radiated interference is avoided; the light
transmittance of the glass and the
light reflection rate of the background plates are improved, so that the
signal-
noise ratio is increased, and high-accuracy sorting is facilitated; the electronic
thermostat is favorable for keeping the temperature in the sorting chamber constant, so that the condition that the change of
light reflection properties of the materials and the light reflection properties of the background plates due to temperature change is avoided, and the sorting accuracy rate is further increased; and compensators are separately arranged on the background plate mounting seats, so that the vibration and local displacement of the equipment can be absorbed, and the background plates can be kept stable.
