Abstract
The utility model discloses a detecting device for measuring color. The existing color measuring instrument is large, thus being not easy to carry; the light path and the structure are complex, and the requirement on the light source stability is higher, therefore the existing color measuring instrument is not suitable for on-line measurement. The utility model comprises a casing, the light source arranged in the casing, a detector, a data processor and an output unit arranged on the casing. The utility model is characterized in that the light source comprises a plurality of light emitting diodes uniformly distributed in a circle. The light emitting diodes have special colors and peak wavelengths. All the light emitting diodes are arranged in equal distances and surround a circle to form a uniform lighting source with a uniform illuminance and without facula. The utility model has small volume, and light weight, is easy to carry, and not influenced by the environmental factor essentially, therefore, the on-line measurement is realized.
Description
Technical field
The utility model relates to a kind of pick-up unit of measuring color, and specifically a kind of is the portable colour photometer of light source with light emitting diode (LED).
Background technology
Existing color measurement instrument structure is made up of light source, detector, data processor and output unit four parts, and light source is by C, D substantially
65, standard illuminantss such as A, halogen tungsten lamp, xenon lamp/light source forms.Such colour photometer volume is bigger, is not easy to carry; Light path and structure more complicated are had relatively high expectations to stability of light source, are subjected to factor affecting such as environment serious, the online detection of incompatibility.
The utility model content
The purpose of this utility model is to overcome the defective that above-mentioned prior art exists, and providing a kind of is the colour photometer of light source with the light emitting diode, and stable performance is easy to carry, can realize online detection.
For this reason, the utility model adopts following technical scheme: portable colour photometer, comprise housing, be positioned at light source, detector, the data processor of housing and be located at output unit on the housing, it is characterized in that described light source is a plurality of light emitting diodes, is circumference uniform distribution.These light emitting diodes have special color and peak wavelength.All light emitting diodes are equidistantly put, and surround a circle, and forming does not have the even uniformly optical illumination light source of hot spot, illumination.LED source just can calculate the object color parameter in conjunction with the spectral characteristic of detector and the spectral reflection characteristic of object.
Described portable colour photometer, light that light emitting diode sends and horizontal line angle at 45, be light and the testee normal to a surface angle also at 45 that light emitting diode sends, the light of light emitting diode shines on the object with 45 ° of directions, and its reflected light is detected device and obtains; Detector is positioned at the centre on plane, light emitting diode place.
The wave band that described portable colour photometer, light emitting diode emit beam is at 380nm-780nm.By the brightness and the fluorescent lifetime of control light emitting diode, and, design light source characteristic in conjunction with the spectral tristimulus value curve.
Described portable colour photometer, the number of light emitting diode are preferably 6-32.
The utility model has following beneficial effect with the light source of light emitting diode as colour photometer: simple in structure, and the stable performance of light source; The colour photometer volume is little, in light weight, is easy to carry; Substantially be not subjected to Effect of Environmental, realized online detection.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings
Fig. 1 is the distribution plan of light source and detector in the utility model.
Fig. 2 is a schematic diagram of the present utility model.
Embodiment
Portable colour photometer as shown in the figure, comprise housing, be positioned at light source 1, detector 2, the data processor of housing and be located at output unit on the housing, described light source is 16 light emitting diodes (LED), and all LED equidistantly put, surround a circle, and with 45 ° of irradiating objects.The wave band that each light emitting diode emits beam between 380nm-780nm, with horizontal line angle at 45, i.e. the light and the testee normal to a surface angle also at 45 that send of light emitting diode, detector is positioned at the centre on plane, light emitting diode place.All LED light simultaneously, but light successively according to different peak wavelengths, and the detector in the middle of being positioned at is made with a silicon photocell.
Principle of work of the present utility model is as follows: the illumination that light emitting diode (being light source) sends is mapped on the object, and its reflected light is detected device and obtains, and obtains faint current signal; This signal becomes voltage signal through behind the signal amplifier, through the A/D analog to digital conversion simulating signal is become digital signal again and sends into single-chip microcomputer processing (MCU); The color parameter that obtains at last can be gone up at liquid crystal display (LCD) (being output unit) and show, also can print by computer (being output unit).
Claims (4)
1, portable colour photometer comprises housing, is positioned at light source, detector, the data processor of housing and is located at output unit on the housing, it is characterized in that described light source is a plurality of light emitting diodes, is circumference uniform distribution.
