Color design experimental instrument based on LED light source

Abstract

The invention discloses a color design experimental instrument based on an LED light source, and the experimental instrument comprises a colored light synthesizing box, a DC voltage-stabilizing power supply, and a guide rail. The experimental instrument also comprises a white screen, an illuminometer, and a miniature spectrometer. The interior of the colored light synthesizing box is provided with three collimating devices, each two of which form an inclined angle of 120 degrees. An upper panel of the colored light synthesizing box is a movable door with a handle. The front panel of the colored light synthesizing box is provided with a circular light hole with the diameter of 10cm, and the inner side of the front panel of the colored light synthesizing box is provides with a slot which is used for placing a plugboard. A side panel of the colored light synthesizing box is provided with three digital display volt-ammeters. The rear panel of the colored light synthesizing box is provided with four LED power supply jacks (three positive wiring terminals and one public negative wiring terminal). The guide rail is placed in front of the colored light synthesizing box. The white screen, the illuminometer or the probe of the miniature spectrometer can be placed on the guide rail according to the test demands, and the miniature spectrometer is connected with a computer. Through the structural design of the light source, the collimating devices enable the scattered light of an LED to be converted into parallel light for output. The light beams are uniform, are clear in imaging, are bright in color, and are easy to compare with the primary color.

Description

technical field [0001] The invention relates to the technical field of teaching instruments in the fields of optics and electricity, in particular to a color design experiment instrument based on an LED light source. Background technique [0002] Chromaticity is a science that studies color measurement, and its task is to study the qualitative and quantitative laws and applications of human color vision. Whether in textile, printing and dyeing, printing, dyes, coatings, plastics, food, paint, construction and other industries, or in metrology, medicine, television, film, photography, landscaping, traffic signals, product identification and remote sensing, information processing and space Various fields such as optics are inseparable from the measurement and research of color. Quantitative measurement of object color is complex, it involves the observer's visual physiology, visual psychology, lighting conditions, observation conditions and many other issues. In order to tra...

Problems solved by technology

These two methods have the same defects. It is difficult for the human eye to recognize the color of the synthesized light, and it is difficult to distinguish the difference between the synthesized light and the light to be matched, and the difference between the synthesized light and the primary color light. The experimental phenomenon is not clear and the demonstration effect is poor; The device only has the demonstration function of "color light synthesis", and the experimental content is relatively simple
