| 摘要 |
The present invention relates to a protection cap of an indirect LED lighting apparatus using reflected light irradiation. The purpose of the present invention is to provide a protection cap maximizing the light efficiency of an indirect LED lighting apparatus using reflected light irradiation by constituting the protection cap so as to effectively transmit, scatter and diffuse the emitted light emitted from the indirect LED lighting apparatus. The present invention is characterized in that the protection cap is constituted so that the incidence angle of the emitted light emitted from the indirect LED lighting apparatus using reflected light irradiation is perpendicular to the cross section of the protection cap. |
