Patent number: 9074751Abstract: A lighting apparatus includes a light reflector, a light emitting diode (LED) and a light-changing film. The light reflector has a concave surface. The LED is disposed under the concave surface of the light reflector to provide the concave surface with light. The light-changing film converts a first light generated by the LED into a second light. For example, the light-changing film may be a fluorescent film receiving the first light and emitting the second light with increased wavelength. The LED and the light-changing film are spaced apart from each other to minimize discoloration of the light-changing film.Type: GrantFiled: June 18, 2009Date of Patent: July 7, 2015Assignee: Seoul Semiconductor Co., Ltd.Inventors: Won-Kuk Son, Yevgeni Aliyev, Osmonalieva Gulmira

Patent number: 7964997Abstract: A lighting apparatus comprises a power unit, a fan unit, a charging unit, a light source unit and a control unit. The power unit receives power from an external power source. The fan unit is rotated using the power supplied from the power unit. The charging unit stores power generated from rotation of the fan unit. The light source unit generates light. The light source unit employs an LED as a light source. The control unit connects the light source unit to the charging unit when power level of the charging unit is greater than a specified level, and the control unit connects the light source unit to the power unit when the power level of the charging unit is lower than the specified level. Therefore, power consumed by the lighting apparatus is reduced and vibration resistance of the lighting apparatus is improved.Type: GrantFiled: September 29, 2009Date of Patent: June 21, 2011Assignee: Seoul Semiconductor Co., Ltd.Inventor: Won-Kuk Son
