Abstract
The utility model relates to a full-color light emitting diode (LED) background light regulating system for a color selector. A basic illumination unit consists of high-power red, green and blue LEDs, a high-power red, green and blue LED circuit board is connected with a control circuit consisting of a singlechip circuit and is arranged in front of a charge coupled device (CCD) lens, and the high-power red, green and blue LED circuit board and a background board form a full-color LED background light regulating system of the basic illumination unit. An angle regulating mechanism of the background board is omitted, the structural design is simplified, the full-color LED background light regulating system adapts to the optimum response requirement of a red, green and blue (RGB) pixels of a colored CCD on the background brightness to the greatest degree, the inherent defect that the background is bright in the middle and is dark at two sides caused by the lens is overcome, the color selection precision is improved, and the full-color LED background light regulating system has the characteristics that the structure design is reasonable, the process performance is good, the length can be in any cascade connection, the brightness can be freely and continuously regulated, the illumination degree is stable, and the service life is long.
Description
Technical field
The utility model relates to the ambient light illumination equipment of online detection instrument, particularly a kind of full-color LED bias light Adjustment System that is used for color selector.
Background technology
The color selector of present domestic employing colored CCD device adopts fluorescent light that background board is thrown light on mostly, comes for detection means variable background luminance to be provided through the angle of adjustment background board.It is inhomogeneous inconsistent to the response of color background light with RGB picture dot colored CCD to cause background luminance caused by the influence of fluorescent lamp and background board reflecting coating, thereby influences accuracy of detection.
Summary of the invention
The purpose of the utility model is exactly for overcoming the deficiency of prior art; A kind of full-color LED lighting engineering is provided; The brightness and the color of illuminator are adjusted easily, to the background luminance optimal response, reached best accuracy of detection with the RGB picture dot that adapts to the colored CCD device.
For realizing above-mentioned purpose; The technical scheme that the utility model adopted is: a kind of full-color LED bias light Adjustment System that is used for color selector; Comprise the base lighting unit; It is characterized in that the base lighting unit adopts high-power red, green, blue LED to form, high-power red, green, blue led circuit plate connects the control circuit that is made up of single chip circuit; High-power red, green, blue led circuit plate is installed in CCD camera lens front, with the full-color LED bias light Adjustment System of background board composition base lighting unit.
The utility model beneficial effect: respectively the operating current of red, green, blue LED (light emitting diode) is controlled through dedicated control circuit, obtained required background luminance and background color, the utility model has saved the background board angle-adjusting mechanism; The design that simplifies the structure, present technique can adapt to the RGB picture dot of colored CCD device to greatest extent to background luminance optimal response requirement, has revised because the dark inherent shortcoming in bright both sides in the middle of the background that camera lens causes; Improved precision of color separation, had reasonable in design, good manufacturability; Length cascade arbitrarily; Brightness adjustment continuously arbitrarily, illumination is stable, the characteristics that the life-span is long.
Description of drawings
Fig. 1, be used for the full-color LED bias light Adjustment System structural representation of color selector.
Among the figure: 1. base lighting unit, 2. CCD camera lens, 3. background board, 4. snifting valve, 5. feeder.
The specific embodiment
Understand the utility model for clearer, describe the utility model in detail in conjunction with accompanying drawing and embodiment:
As shown in Figure 1; A kind of full-color LED bias light Adjustment System that is used for color selector; Base lighting unit 1 adopts high-power red, green, blue LED (light emitting diode) to form, and high-power red, green, blue LED (light emitting diode) circuit board connects the control circuit that is made up of single chip circuit;
High-power red, green, blue LED (light emitting diode) circuit board is installed in CCD camera lens 2 fronts, with the full-color LED bias light Adjustment System of background board 3 composition base lighting unit.
Material gets into the color selector sort channel from feeder 5; Through form the single full-color LED bias light Adjustment System of base lighting by high-power red, green, blue LED (light emitting diode) and background board 3; Luminance signal reaches control circuit, respectively the operating current of red, green, blue light emitting diode is controlled through dedicated control circuit, obtains required background luminance and background color; Material is after CCD camera lens 2 detects, and color selector detection system control snifting valve 4 is worked.
According to above-mentioned explanation, can realize the scheme of the utility model in conjunction with art technology.
