In life, we often see led street lights flashing for a long time, but I don't know why this happens. So today, Led Street Light Factory uses a simple way to share the measurement LED strobe needs. The conditions that are met.
First of all, we must understand the following conditions when measuring LED strobe:
1. The photoelectric conversion detector used must have a fast response speed and can be quickly sampled.
2. The detector must be able to simulate the human eye's curve of light, the curve of the visual function, which can simultaneously measure illuminance or brightness.
3. With software computing capabilities.
The current instrument for measuring stroboscopic light is a photometer. The ambient temperature during the test should be controlled between 20 and 30 °C. The photometer price is cheaper than the spectrometer, but it can only measure one wavelength at a time, but it is enough in the strobe. Because in the visible light band, the intensity changes are synchronous and proportional for the same luminaire. In a switching cycle, we only need to measure the luminous flux curve of a specific wavelength, calculate the fluctuation depth according to the peak and valley values, and calculate the average luminous flux (using the integral method to obtain the area S of one cycle in Figure 1) The average luminous flux is obtained by dividing the period length T, and then integrating the Q1 region, Q2 = S - Q1, and the stroboscopic index can be calculated from Q1 and Q2.
