High power chip on board light emitting diode (HPCOBLED) are a promising solid state light technology for a variety of lighting applications. In this study, we studied temperature effect on luminous flux of HPCOBLED using VMI-PR-001 system of Vietnam Metrology Institute. The results according to the temperature Tc is increasing, luminous flux reduced. Especially HPCOBLED is larger power, decreasing luminous flux is larger. Reason of this is chance power.   HPCOBLED model describes the temperature affection on luminous flux of HPCOBLED. The results of HPCOBLED model matched with that measured by the luminous flux measurement system (VMI-PR-001, Vietnam).

This paper presents a new method for micro-aperture measurement based on luminous flux. The principle and the structure of micro-aperture measurement system are introduced in detail. Compared with previous measurement methods, the proposed method has several advantages: The measuring head with array line structure can measure several apertures’ area directly at the same time. The shape of the aperture is not limited to a circle or any other shape. It is a measuring technique with high precision and low cost. The test results show that the uncertainty is mm of a circular 0.5 mm diameter aperture, and the average linearity value is 3.47% to the aperture which diameter in the range from 150 to 500um.
