Publication number: 20120314420Abstract: A lighting apparatus includes a light source module, a heat sink holding the light source module and a light-permeable cover mounted to the heat sink and covering the light source module. The cover is adhered to the heat sink by an adhesive agent applied with a gap formed on at least one part between the cover and the heat sink. The inside and outside of the lighting apparatus can be communicated to each other due to the gap. Since the inside and outside of the lighting apparatus are communicated to each other, the problems of temperature difference and pressure difference between inside and outside of the lighting apparatus can be suppressed so that the occurrence of defects because of condensation and the like can be prevented.Type: ApplicationFiled: February 18, 2011Publication date: December 13, 2012Inventors: Shoji Yamamoto, Hideyuki Akao

Publication number: 20120236573Abstract: A lighting apparatus includes LEDs and a light-permeable cover passing the light emitted from the LEDs and an anti-scattering film is arranged on the cover for preventing the scattering of fragments when the cover fractures. The anti-scattering film contains a dispersing agent for dispersing light. Since the anti-scattering film containing a dispersing agent is arranged on the cover, when the lighting apparatus is damaged by falling, the scattering of fragments of the cover is preventable, and the glare can be reduced because the light emitted from the LEDs are dispersed through the dispersing agent contained in the anti-scattering film. Since the anti-scattering film containing the dispersing agent is arranged on the cover, the deterioration of luminance flux is preventable as compared to a case of arranging on the cover a member for anti-scattering and a member for reducing glare separately.Type: ApplicationFiled: October 18, 2010Publication date: September 20, 2012Inventors: Shoji Yamamoto, Hideyuki Akao
