Fig. 5 is the schematic diagram driving the configuration device of parameter according to the preferred light fixture of the embodiment of the present invention.
As shown in Figure 5, this embodiment can as preferred implementation embodiment illustrated in fig. 1, and the light fixture of this embodiment drives the configuration device of parameter except the control assembly 10 comprising above-described embodiment, also comprises light-blocking member 20 and measurement component 30.
The shading space of light-blocking member 20 inside may be used for arranging light fixture to be configured.Light fixture to be configured may be used for receiving the multiple driving parameter sampling values corresponding with each individual color channel, and each driving parameter sampling value in multiple driving parameter sampling value may be used for driving each individual color channel.
Measurement component 30 can be arranged in shading space, be connected with control assembly 10, may be used for when each driving parameter sampling value drives each individual color channel, measure the current illumination value of each individual color channel, and using current illumination value as the illumination sampled value corresponding with each driving parameter sampling value.As shown in Figure 6, measurement component 30 can comprise tristimulus colour examining module 302 and signal processing module 304.Wherein, tristimulus colour examining module 302 can comprise three groups of filters and corresponding photodiode L circuit, such as, three groups of filters can be ruddiness filter R, green glow filter G and blue filter B, are respectively used to the energy of the red spectral band of measurement visible ray, green light band and blue wave band.The signal that signal processing module 304 may be used for tristimulus colour examining module 302 records is converted to chromaticity coordinates and illumination.Particularly, measurement component 30 can be colorimeter.

In embodiments of the present invention, for each individual color channel in light fixture, all can first drive parameter sampling value and illumination sampled value to carry out matching to many groups that record in advance, then judge the corresponding relation between the driving parameter of this individual color channel and object illumination according to the result of matching.Simply, for the light fixture that the linearity driven between parameter and illumination is higher, as Light-Emitting Diode LED (LightEmittingDiode) light fixture utilizing the voltage signal of below certain voltage threshold value or the pwm signal below certain frequency threshold value to control, above-mentioned process of fitting treatment can adopt the mode of linear fit.But this execution mode that also non-invention is unique, such as, for the light fixture that the linearity is poor, then also can adopt the corresponding relation between other fit approach more complicated driving parameter of acquisition and object illumination, the present invention is not construed as limiting this.
Based on this, in embodiments of the present invention, aforementioned fitting result can be the result adopting linear fitting obtain or the result adopting interpolation method to obtain.
Particularly, linear fit can be carried out in the following manner, and obtain linear fit result:
Linear fit is carried out to multiple driving parameter sampling value and multiple illumination sampled value; Wherein, the result according to linear fit obtains corresponding relation: E=p*c+E0, and wherein, E represents the object illumination of each passage, and c represents the driving parameter of each passage, p and E0 is constant coefficient; Wherein, particularly, the driving parameter of each passage can be obtained according to following calculating formula: c=(E-E0)/p.
For the fitting result shown in Fig. 8.In fig. 8, solid black round dot can represent sampled point, the abscissa value of this sampled point can represent driving parameter sampling value, the value of the multiple PWM duty ratios also namely preset, the ordinate value of this sampled point can represent illumination sampled value, the brightness value of each the lower measured individual color channel also namely in the plurality of PWM duty ratio.As can be seen from Figure 8, concerning should individual color channel, it drives the linearity between parameter and illumination better, and the process of fitting treatment mode of linear fit therefore can be adopted to carry out matching to it, and fitting result can be the straight line shown in Fig. 8.Namely under above-mentioned scene, constant coefficient p can be the slope of straight line, and constant coefficient E0 can be approximated to be zero, is also proportionate relationship substantially as the duty ratio of driving parameter and object illumination.
Particularly, interpolation fitting can be carried out in the following manner, and obtain linear fit result:
Interpolation method is adopted to carry out process of fitting treatment to multiple driving parameter sampling value and multiple illumination sampled value; Wherein, result according to process of fitting treatment obtains corresponding relation: E=(E2-E1) * (c-c1)/(c2-c1)+E1, wherein, E represents the object illumination of each passage, c represents the driving parameter of each passage, c1 represents in multiple driving parameter sampling value one and c1<c, c2 represents in multiple driving parameter sampling value one and c2>c, E1 represents one corresponding with c1 in multiple illumination sampled value, and E2 represents one corresponding with c2 in multiple illumination sampled value; Wherein, the driving parameter of each passage is obtained according to following calculating formula: c=(c2-c1) * (E-E1)/(E2-E1)+c1.
