Publication number: 20140347841Abstract: A lighting apparatus including a base, a light cover, an optical element, and at least a light emitting element is provided. The light cover having a first opening is disposed on the base and together with the base forms a space. The optical element is fixed on the light cover and substantially covers the first opening of the light cover. The light emitting element is disposed in the space. A light emitted by the light emitting element passes through the optical element and emits from the light cover to form an illumination property of the lighting apparatus, wherein the light cover together with the optical element is movable with respect to the light emitting element. When the light cover and the optical element have different relative positions with respect to the light emitting element, the illumination properties are different.Type: ApplicationFiled: March 3, 2014Publication date: November 27, 2014Applicant: LITE-ON IT CORPORATIONInventors: Sheng-Hsiung HU, Wei-Wen SHIH, Wen-Kwei LIANG, Chung-Dao CHEN
