Description
Technical field
The utility model relates to optical measurement techniques, is specifically related to a kind of light-emitting diode detection device.
Background technology
Utilize the three primary colors principle, test out the shared ratio of three kinds of primitive color lights (redness, blueness, green) in the light that light emitting diode sends, thereby obtain which kind of color of light.The configurable light emitting diode induction chip of microprocessor is selected different color channels, then by electric current-frequency converter, export the frequency of 50% pulsewidth, thereby test out the value of RGB, the size of frequency represents light intensity, and the scope of frequency is adjustable, and is greatly to 600KHZ, little of 12KHZ.Because the inner integrated 8X8 of this induction chip is 64 photodiode altogether, it is four types that these photodiodes are divided into, and 16 photodiodes have red filter, and 16 have blue electric-wave filter, and 16 have green filter, all the other 16 band filters not.
Use the induction chip of different colours, the size of the voltage that induces or the pulsewidth of frequency is as weighing the light intensity size, the corresponding light wavelength of frequency, the color that the scope of different wave length is corresponding different.The induction chip of single passage is formed a little board test.No microprocessor control.Shortcoming: speed is unhappy, and the available velocity scope is narrower.Precision is not very high, the antijamming capability relative deficiency.Need additional microprocessor control.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of light-emitting diode detection device.
The technical solution of the utility model is: a kind of light-emitting diode detection device comprises the LED tablet of gathering light emitting diode to be measured, control panel and image data is analyzed the host computer of demonstration that described host computer connects the LED tablet by control panel.
Further improvement of the utility model comprises:
Described host computer is connected with described control panel with the RS232 interface by USB interface.
Described LED tablet is connected by the I2C bus data-signal of gathering with described control panel.
The LED tablet is gathered the light signal of light emitting diode to be measured by connected optical fiber tube.
Use the TCS3200D color sensor in the LED tablet.
Described control panel comprises single-chip microcomputer PIC16F877A and monolithic processor controlled USB or RS232, and the data of LED tablet collection are sent to the meter host computer.
Technique effect of the present utility model is: can test the many light emitting diodes of quantity simultaneously; Have battery saving mode, utilize optical fiber light pipe and the lid that is in the light stops external interference of light, use simple, adjustable-speed, can height can be low, the precision height, antijamming capability is strong.
