The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Among the utility model embodiment, light source comprises two light emitting diode (Light Emitting Diode that produce different glow colors at least, LED), by luminance or the brightness ratio of adjusting each LED, build various life luminous environments, simulate the true effect of clothing color under the actual light environment.

Fig. 1 shows the schematic diagram of the lighting system that the utility model first embodiment provides, and for convenience of explanation, only shows the part relevant with the utility model embodiment.

Please refer to Fig. 1, the light source of the lighting system that the utility model first embodiment provides is made of a plurality of LED such as A, B, C, D, wherein each LED has different glow colors, drive circuit 11 provides driving DC voltage by output end vo ut for each LED, the conducting voltage of considering LED is lower, for the influence that prevents that electromagnetic interference is luminous to LED, control the brightness of each LED better, between each LED and drive circuit 11, also be connected with along attitude and suppress diode T.

As shown in Figure 1, path between each LED and the drive circuit 11 is by switching device K control conducting, on off state by each switching device K of control break in the present embodiment, make each LED be in luminous or luminance not, thereby made up by the different glow colors that light source sends, simulate various luminous environments, Fig. 1 is the operation principle that example shows present embodiment with four colour systems system, on-off controller 12 is controlled the state of A lamp and B lamp simultaneously, on-off controller 13 is controlled the on off state of C lamp and D lamp simultaneously, suppose the luminous environment that when on-off controller 12 control A lamps and B lamp are luminous, can simulate the open air at noon, then can consider when the user need try some formal dress on, to select for use by on-off controller 12 to make A lamp and B lamp luminous; Suppose the luminous environment that when on-off controller 13 control C lamps and D lamp are luminous, can simulate the dinner party occasion, then can consider when the user need try some evening dress on to make C lamp and D lamp luminous by on-off controller 13; Suppose when on-off controller 12 and on-off controller 13 and control A, B simultaneously, can simulate the luminous environment of public place of entertainment when four lamps of C, D are luminous, then can consider when the user need try some leisure civilian dresses on by on-off controller 12 and on-off controller 13 control A, B, C simultaneously, D four lamps are luminous.

Clearly, the control principle of present embodiment below only has been described for example with regard to four colour systems system, can according to circumstances select the LED of any amount during concrete enforcement, and can select to control simultaneously that any one LED or any one group of LED are luminous comes the simulated light environment, specifically repeat no more.

The luminosity of considering LED is relatively more responsive to the size of driving voltage, the utility model second embodiment reaches the effect of accurate simulated light environment by the brightness of controlling each LED, Fig. 2 shows the schematic diagram of the lighting system that the utility model second embodiment provides, for convenience of explanation, equally only show the part relevant with the utility model embodiment.

Please refer to Fig. 2, the light source of the lighting system that the utility model second embodiment provides is made of a plurality of LED such as A, B, C, D, and wherein each LED has different glow colors, and all can adjust luminosity to its driving voltage that applies by changing; Drive circuit 21 provides driving DC voltage by output end vo ut for each LED, is connected with equally along attitude to suppress diode T between each LED and drive circuit 21.

Store the parameter of various luminous environments in the drive circuit controller 22, the size of driving DC voltage that is used to control led drive circuit 11 outputs is to change the luminosity of LED, the light of shades of colour, various brightness is combined, simulate various luminous environments more accurately, the light that makes fitting room is farthest near a day spectrum line.

For example, suppose that current light source is four colour systems systems, and according to the luminous environment parameter of drive circuit controller 22 storage, when the luminance parameter of A, B, C, D lamp is respectively A1, B1, C1, D1, can simulate the luminous environment of open air at noon, then can consider when the user need try some formal dress on, to select for use this kind luminous environment; The luminous environment that can simulate the dinner party occasion when the luminance parameter of A, B, C, D lamp is respectively A2, B2, C2, D2 then can consider to select for use this kind luminous environment when the user need try some evening dress on; When the luminance parameter of A, B, C, D lamp is respectively A3, B3, C3, D3, can simulate the luminous environment of public place of entertainment, then can consider when the user need try some leisure civilian dresses on, to select for use this kind luminous environment.
