Abstract:
PROBLEM TO BE SOLVED: To provide a light distribution characteristics measurement device and a method for the same which can efficiently measure light distribution characteristics of a light source without enlarging a device structure.SOLUTION: A light distribution characteristics measurement device is for measuring light distribution characteristics of a source. The light distribution characteristics measurement device includes a plurality of detectors placed by prescribed relative relations. A detection range of one detector overlaps, at least partially, with detection ranges of other adjacent detectors. Moreover, the light distribution characteristics measurement device includes: drive means which, by driving the plurality of detectors integrally, updates position relations with respect to light sources of the plurality of detectors; and calculation means which performs processing according to at least either the relative relations among the plurality of detectors or the overlaps of the detection ranges on the basis of respective results of detection acquired by the plurality of detectors with identical timing, and calculates light distribution characteristics of the light sources.
Abstract:
적어도 하나의 파장 선택 광 검출기(10), 렌즈(20) 및 개구(30)를 포함하는 광 센서(1)가 제안된다. 파장 선택 광 검출기는 센서 위에 떨어지는 미리 정해진 파장 범위 내의 광을 검출하는 것을 허용한다. 렌즈는 광 검출기 위에 광을 투영하고 개구는 광 센서의 뷰의 필드를 한정한다. 광 검출기(10), 렌즈(20), 및 개구(30)는 텔레센트릭 구성으로 배치된다. 바람직하게는, 이것은 개구에 입사하는 광의 방향과 무관하게 미리 정해진 각도들의 범위 내의 광이 파장 선택 광 검출기 위에 부딪히게 하여, 파장 선택 광 검출기의 각도 의존 응답을 제거한다.
Abstract:
PURPOSE: A system for testing properties of a light source and a testing method using the same are provided to precisely test a light source by installing a shading member. CONSTITUTION: A method for testing properties of a light source is as follows. A calibration factor is calculated(S10). Multiple light source modules are installed in color sensors installed in a divided area to test the manufacturing state of light sources(S20). Light emitted from the light sources are measured using the color sensors(S30). A characteristic value of the light sources is calculated based on a data measured from the color sensors(S40).
