【Abstract】 In order to evaluate the quality of the electrodeless lamp body, in this paper, a method for measuring the luminous uniformity of its surface is presented. It is based on the application of optical fiber to get the normal light output of each surface element. Through the use of photovoltaic cells, amplifier circuits and the STM32(a 32-bit microcontroller of STMicroelectronics) control system, the voltage data corresponding to the relative luminance of the electrodeless lamp body’s surface is obtained, meanwhile, the luminous uniformity is achieved. In addition, according to the experimental verification, analysis of the electrodeless lamp body luminance uniformity by this method can be used as a way to evaluate the quality of the lamp body.更多还原
