When the illuminant 81 generates a projected light, the projected light passes through the light-injecting portion 81 to be projected into the environmental space. The light portion 811 is in the shape of a notch for deflecting incident light to increase the intensity of the emitted light. Please refer to the second figure, a white light LE:D illumination system disclosed in U.S. Patent No. 6,234,645, which has a lampshade 9 〇 and at least three illuminating diodes 9 illuminating diodes 91. The visible light having a predetermined wavelength is emitted. The inner wall of the lampshade 90 is coated with a layer of phosphor powder to cause a diffusing effect on the light of the light-emitting diode 91 to achieve the purpose of uniformity. However, a disadvantage of the prior art is that the lamp cover only passively diffuses the light projected thereon, and does not actively direct the light to an appropriate direction, so the light usage rate is still low, so the illumination system adjusts the brightness. There is no significant effect on the use of the part and the light source. [New content] The main purpose of this creation is to provide an improvement of the lighting structure, in which the application of light to the ball (four) shape and the reflection of the ball, so that the out of the county is controlled within a certain angle of light and effectively reduce the light loss, thus making the overall light extraction efficiency effective.
