The method further includes the step of: a') issuing a start signal to the central controller of the illumination system by operating the control button 50. The command to adjust the backlight color is input to the illumination system according to the activation signal, so that the illumination system 10 detects The color of the external environment changes, and the color of the backlight source is changed according to the change. In the embodiment, the illumination system 10 detects the color of the external environment and the backlight source only when the control button 50 is manipulated. In addition, due to the relatively high price of white light LK), the light source in the illuminator 1〇2 can also be replaced by a lower-priced green LED, and with the LED adjustment of different color lights. The generated backlight color adjustment signal. In other words, when the right first light source F1 is a predetermined color light other than white light, the second light 11 201028598 is based on her The intrinsic color of the g surface is biased toward the predetermined color light. For the first time, the light source π is red light, and the '', ', and 'colors of the surface of the object 4g, the color of the second light source F2 after the reflection will be reddish. The green is so 'the central controller 1〇1 receives the signal from the color sensor 1〇3' and then parses the object 4 based on the color light of the first-light source F1 (such as the work light in this example). The RGB signal of the inherent color of the surface (such as green in this example) generates a backlight color adjustment signal based on the analyzed bile signal. 〇 If the detection result is made to warm the color or cool color, the light source in the illuminator 102 The warm color light source or the cool color silk can also be used, and the central controller 101 analyzes the inherent color of the surface of the object 40, and directly adopts the adjustment result of the warm color light source or the cool color light source. The predetermined color light of the first light source F1 affects the color of the second light source F2 after reflection. The effect of different light source colors on the color change of the object 4 varies (substantially the strongest red light, the second white light, and the green again) , blue, cyan, purple, etc.) 'also depends on the strength of the first light source F1, the distance between the adjacent object and the illuminated object 40, the surface roughness of the illuminated object 4, and the color. Generally, the closer the adjacent object is to the illuminated object 4〇, the smoother the surface of the illuminated object 40, or the stronger the reflected light, the effect of the predetermined color light of the first light source 对 on the color of the illuminated object 40. It is also bigger. Conversely, the farther away from the adjacent object, the rougher the surface, or the lighter the color, the smaller the object 40 is affected by the predetermined color light of the first light source F1. The electronic input device can be a mouse or a keyboard. Next, taking the mouse as an example, the illumination system and method for changing the backlight color of the present invention are described in detail as follows: A mouse includes a central controller built in the housing and an illuminator connected to 12 201028598 respectively. The color sensor 'where the illuminator is disposed on the body portion for emitting light to the outside of the electronic input device, the first source is white light, and the bottom of the mouse case is provided with a transparent partition plate to emit light The whiteboard emits white light to the outside of the mouse. In general, the desktop or the mouse pad, that is, the outward light_white light can be illuminated on the desktop or slide 2: color sensing n, the receiving the first light source through the object The surface is reflected back = two light sources, and the RGB money is generated. The color of the second light source is the same as the inherent color of the object table = the same age as the desktop or the mouse pad; the central controller 2 is used for receiving the color sensing. The RGB signal emitted by the device is recorded according to the RGB 彳5 射 射 丝 , , , η η η η η η η η η η η η η η η η η η η η η η η η η η η η η η η η Even the color of the backlight Both pads same desktop or 'month color change of the latter varies as a backlight color, changing to achieve colorful visual effect. However, the above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the practice of the present invention, that is, simple equivalent changes made in accordance with the contents of the present invention and the description of the invention. And modifications are still within the scope of the claims of the present invention.
