The present invention relates to a color measurement device. In detail, more accurate color detection and real-time storage / transmission of the detected data can be achieved, and the illumination of the measurement space can be more precisely adjusted, and the configuration of the light source for realizing the illumination can be extended and the service life can be extended. The present invention relates to a booth type color measurement device.

A color measuring device (hereinafter, referred to as a measuring device) is commonly referred to as a “color sensor”, and is a device that detects and processes colors of various objects having a specific color, so that the processed data can be visually confirmed.

Such measuring devices are applied in the textile industry, in the field of painting, books, publications, etc. It is widely applied in food, agriculture, forestry, fisheries, rubber, plastics, cosmetics and other industries that manage products. In particular, in the textile industry, the weight of color measurement is mainly evaluated in the fashion industry, such as clothing, shoes, and jewelry. This is due to the fact that color is a very important emotional factor in the fashion industry because it is a key strategic factor for the creation of various business models due to accurate color measurement and fashion products produced using it.

The conventional measuring device as described above is a light source for irradiating light to a target of a certain color, a light receiving sensor for receiving and detecting when the light emitted from the light source is reflected on the object, and transmits the signal sensed by the light receiving sensor It is composed of a dedicated color extraction control device for receiving and processing. Such a measuring device emits light from a light source and irradiates the object, and when the reflected light reflected and returned to the object is detected by the light receiving sensor, the signal detected by the light receiving sensor is transmitted to a dedicated processing device in the form of a frequency for each color. Is entered. The input frequency signal is extracted with color data corresponding to each frequency band in contrast with the color profile already input to the dedicated color extraction control device, and the extracted color data is output to a printer, a monitor, and the like.

In particular, when an object for measuring color among the measuring devices as described above is exhibited / stored as a product, it is proposed to be manufactured in a booth form to measure an illumination state irradiated with the product. In such a booth-type measuring device, a measurement space into which an object is put is formed. At this time, the measurement space is a built-in lighting device to form an illumination state of the same conditions as the illumination state that the object is to be displayed as a product.
