    Abstract: A light measurement system measures light characteristics of a plurality of light sources and includes a processing unit, a plurality of capturing modules, a plurality of signal conversion units, and a demultiplexing unit. The processing unit generates a control signal for controlling the capturing modules to capture the light characteristics of the light sources. After capturing the light characteristics, the capturing modules output captured frequency-related data corresponding to the light characteristics respectively. Then, the capture frequency-related data are converted into capture bit codes by the signal conversion units respectively. Under the control of the processing unit, the demultiplexing unit selectively sends the capture bit code of each of the signal conversion units to the processing unit. Accordingly, the light measurement system measures the light sources synchronously and allows the demultiplexing unit to send the capture bit code of any one of the light sources to the processing unit.

  • Patent number: 8305576
    Abstract: 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.
