Compact Goniophotometer (Model: HP880D)
1.Introduction
Compact goniophotometer is applied to test small LED lamps (such as halogen lamp, cup lamp, spotlight, bulb and etc.) and high power LED chips. The equipment do not need dark room due to it includes a dark chamber with light diaphragm. The test process is controlled by computer with software, the test method meets the requirement of CIE127 and IEC61341, PDF test report, IES, LDT and CIE files can be output directly.
