LED照明行业发展了不到10年，就已经有了巨大的成就，LED球泡灯、面板灯、管装灯条都已经投入了使用中。LED灯主要是利用pn结之间的能量的转换来达到发光的目的，因此LED更加节能，环保。通过蓝光激发黄色荧光粉使LED发出白光，光效可达120流明，其光的单色性好。LED的平均使用寿命可达到100,000小时，大大降低灯具文护换新成本。Led灯还可以集成化一体化来实现大功率的LED灯具。LED的这些优点使得LED在重大照明场合成为主要照明灯具。
本课题主要针对LED侧入式平板灯的照度均匀性以及亮度色温的测试进行研究，并利用软件模拟出LED平板灯以及平板灯的照度的分布及均匀性。本文将介绍平板灯的原理以及其主要部件的工作原理设计要点，利用proe三文造型软件设计出LED平板灯的模型，再使用tracepro光学设计软件模拟仿真LED平板灯的照度、亮度。还要对三种不同功率、芯片数量、灯条排布的LED平板灯进行亮度、照度、色温的测试，并且计算亮度照度的均匀性。照度的实验结果还将与仿真的结果进行比较。

Test analysis of LED flat panel light system
Abstract
Since Edison invented the light bulb, human economic development has become more rapid, more effective. People continue to introduce new, more and more lighting equipment filled with people's lives. In the future, people need to more convenient lighting equipment, more intelligent human lighting thinking is the future mainstream development direction. In order to achieve this goal, a new type of intelligent lighting equipment, which is LED.
LED lighting industry has developed less than 10 years, has been a tremendous achievement, LED bulb lights, panel lights, tube lights are already put into use. LED lamp is mainly used to convert the energy between PN junction to achieve the purpose of the light-emitting, and therefore LED more energy saving, environmental protection. The blue light yellow fluorescent powder to emit white light LED, luminous efficiency of up to 120 lumens, the light color is good. The average service life of LED can reach 100000 hours, and the new cost of lamps and lanterns maintenance is greatly reduced.. Led lamp can also be integrated to achieve high-power LED lamps. These advantages of LED make the LED major lighting occasions become the main lighting lamps.
This topic mainly for side LED flat lamp illumination uniformity and brightness temperature of test research, and use the software to simulate the distribution of the illumination of the LED flat lamp and lamp flat and uniformity. Will be introduced in this paper flat lamp principle and working principle of the main components of the design points, using proe three-dimensional modeling software design LED flat lamp model, and then use the optical design software TracePro simulation simulation LED flat lamp illuminance, luminance. Also on three different power, chip number, light bar arrangement of LED panel light for brightness and illuminance and color temperature test, and the calculation of the uniformity of the brightness of illumination. The experimental results of the illumination are also compared with the results of the simulation.
Keywords: LED panel light, brightness test, test illuminance, color temperature test, the light guide plate, diffusion plate, proe three-dimensional design software, tracepro optical design software
