Fig. 1 gives the present invention the theoretical foundation realizing color sensation control method with coordinate form.Fig. 1 is only an example of the relation illustrating brightness and colour temperature.In the figure, transverse axis X is expressed as any brightness degree, and longitudinal axis Y is expressed as any color temperature levels.According to the instance basis of Fig. 1, then brightness degree may correspond in brightness degree vector L=(L arbitrarily 0, L 1, L 2..., L m), and color temperature levels may correspond in color temperature levels vector CT=(CT arbitrarily 0, CT 1, CT 2..., CT n), wherein L 0=CT 0=0, and the maximum L of wherein brightness value mbe such as 960, the maximum CT of colour temperature value nbe such as 30 (being changed to example with integer incremented/decremented).In a preferred example, each brightness degree corresponds to an element L in brightness degree vector m, and each color temperature levels corresponds to an Elements C T in color temperature levels vector n, m ∈ [0, M], n ∈ [0, N].
Fig. 5 is the flow chart of the control method for LED light source illustrated according to the embodiment of the present invention.In the control method embodiment shown in Fig. 5, perform following process.
In step 100, the present intensity L of described LED light source is obtained awith current colour temperature CT a.
In step 200, the object brightness L for regulating LED light source of input is obtained bwith target colour temperature CT b.Here, based on the example of Fig. 1, L aor L b∈ [0,960], CT aor CT b∈ [0,30].L aor L brepresent any two end points, the similarly CT in brightness degree vector aor CT brepresent any two ends point in color temperature levels vector.That is, described brightness L is set aand L bfor from preset minimum brightness to one of brightness degree in the adjustable range of maximum brightness.Meanwhile, described colour temperature CT is set aand CT bfor one of color temperature levels in from the lowest color temperature preset to the adjustable range of most high color temperature.
In step 300, present intensity L is utilized awith current colour temperature CT aand object brightness L bwith target colour temperature CT bset up a linear relationship, as shown in fig. 1.In the present embodiment, this linear relationship represents by a predefined function relation.
Such as, when present intensity and current colour temperature correspond to the A point in Fig. 1 and object brightness and target colour temperature correspond to the B point in Fig. 1, the linear relationship that the line segment 1 that formed by connection A and B 2 is such can be set up.Such as, when present intensity and current colour temperature correspond to the A1 point in Fig. 1 and object brightness and target colour temperature correspond to the B1 point in Fig. 1, the linear relationship that the line segment 3 that formed by connection A1 and B1 2 is such can be set up.Such as, when present intensity and current colour temperature correspond to the A2 point in Fig. 1 and object brightness and target colour temperature correspond to the B2 point in Fig. 1, the linear relationship that the line segment 2 that formed by connection A2 and B2 2 is such can be set up.
In step 400, calculate the color sensation regulated variable corresponding with above-mentioned linear relationship, in the present embodiment, brightness and the separate adjustment of colour temperature can be adopted or synchronously realize the embodiment that brightness and colour temperature regulate.

Cool colour component C=CT nl m(1)
Warm colour component W=(30 – CT n) L m(2)
Like this, color sensation regulated variable (C, W) m,nbe (CT nl m, (30 – CT n) L m).That is, (C, the W) at coordinate (m, the n) place in Fig. 1 m,nvalue can calculate according to above-mentioned formula (1) and formula (2).As shown in Figure 1, the upper right corner in each crosspoint of the grid in Fig. 1 all illustrates the value of corresponding (C, the W) calculated.
