The specific embodiment

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

In the embodiment of the invention, the characteristic according to blue light or the easier alleviation of green glow people kopiopia makes the glow color of LED light fixture realize adjustable, when the people needs relieving fatigue, control LED light fixture sends blue light or green glow, and in general illumination situation, still controls the LED light fixture and send white light.

Fig. 2 A, Fig. 2 B, Fig. 2 C, Fig. 2 D show the structure of the LED light fixture that first embodiment of the invention provides, and for convenience of description, only show part related to the present invention.

With reference to Fig. 2 A and Fig. 2 B, be distributed with the led light source that comprises white light LEDs 22 and blue light or green light LED 23 on the circuit board 21, the light that white light LEDs 22 and blue light or green light LED 23 send transmission after LGP 24, light diffusing sheet 35 effects is gone out, circuit board 21, light place shell 26 through LGP 24, light diffusing sheet 25, circuit board 21 is positioned at a side of LGP 24 and light diffusing sheet 25 among Fig. 2 A, be side-light type LED light fixture, and circuit board 21 is positioned at the below of light diffusing sheet 25 among Fig. 2 B, does not need LGP 24.Blue light or green glow intednsity circuit 27 link to each other with blue light or green light LED 23 by circuit board 21, in order to the brightness of control blue light or green light LED 23.

Because blue light or green wavelength are shorter, be imaged on before the retina, impelling eyes to reconcile loosens, make a ciliary muscle obtain having a rest, thereby can alleviate people's kopiopia, the easier maintenance notice of people is concentrated, the embodiment of the invention is according to the characteristic of blue light or the easier alleviation of green glow people kopiopia, in White LED light source, add blueness or green light LED chip, the user can control the LED light fixture and send blue light or green glow when the needs relieving fatigue, shown in Fig. 2 C, blue light on the shell 26 or green glow gauge tap 281 are connected with blue light or green light LED 23 by circuit board 21, the user can be by blue light or green glow gauge tap 281 control blue lights or green light LED 23 work when the needs relieving fatigue, and can be by the brightness of blue light or green glow intednsity circuit 27 control blue lights or green light LED 23, and in general illumination situation, still send white light by the white light gauge tap on the shell 26 282 control LED light fixtures, wherein on the circuit board 21 distribution of led light source shown in Fig. 2 D.
