As shown in fig. 19, the arrows in the figure indicate the direction of the light of the LED light source 41, when the light is emitted from the LED light source 41, a part of the light passes through the slits of the comb teeth structures 4712 of the disk-shaped body 471 of the light reflecting component and then passes through the lampshade 43 to be emitted to the outside of the lamp body, and the other part of the light is reflected and refracted by the light reflecting surface of the disk-shaped body 471 of the light reflecting component (including the bottom surface of the comb teeth structures 4712) and the light reflecting surface of the outer wall of the cylindrical body and then passes through the lampshade to be emitted to the. Thereby realizing the light distribution requirement defined by the energy star.
In the ninth embodiment, the method of the present invention,
referring to fig. 20, the LED bulb according to the present invention, which meets the requirement of energy star light distribution, is different from the eighth embodiment in that the disk-shaped body 471 of the light reflecting member 47 is not provided with a comb structure. The LED light source 41 on the LED light source panel corresponds to the periphery of the pillar support, and the projection part of the contour of the disc-shaped body 471 on the LED light source panel shields the LED light source on the LED light source panel.
In the embodiment example ten, the method comprises the following steps of,
referring to fig. 21, the difference between the LED bulb according to the present invention and the energy star light distribution requirement of the eighth embodiment is that the comb tooth structure 4712 of the disk-shaped body 471 of the light reflecting member 47 is in a twisted blade shape.
The above embodiments are only used to further illustrate the LED light bulb according to the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention fall within the protection scope of the technical solution of the present invention.
