20090109428 | Integrating Photometer for Measuring Total Flux of Light Generated from Light Source to be Measured, and Method for Measuring Total Flux of Light through Use of the Same - A mirror is provided with a light source window and an illumination window each establishing communicative connection between an inner face side and an outer side of a hemispherical unit. The light source window is an opening to which a light source OBJ to be measured is attached mainly. The illumination window is an opening for guiding a flux of light from a correcting light source used for measurement of self-absorption toward the inner face of the hemispherical unit. A self-absorption correcting coefficient of the light source OBJ is calculated based on an illuminance by a correcting flux of light in a case where the light source to be measured OBJ in a non-light emitting state is attached to the light source window and an illuminance by a correcting flux of light in a case where a calibration mirror is attached to the light source window. | 04-30-2009 |

20100296082 | APPARATUS AND METHOD FOR MEASURING TOTAL LUMINOUS FLUX - In a total luminous flux measurement apparatus according to an embodiment, a total luminous flux emitted by an object is calculated based on a result of measuring illuminances using a measuring unit when providing relative movement between the object and an integrating unit to expose a substantially entire light emitting surface of the object to an inner space of the integrating unit. Specifically, under conditions that the object is disposed to penetrate the integrating unit from one sample hole to the other sample hole, a luminous flux of a portion of the object within the inner space of the integrating unit is measured, then the integrating unit is moved relative to the object, and a luminous flux of a portion accordingly contained in the inner space of the integrating unit is measured. | 11-25-2010 |
