[Abstract]:For electric light source, "green lighting" has been a new symbol of lighting industry. Pole-less lamp is a new light source developed in recent years. It is based on the principle of electromagnetic induction, no filament, no electrode, long life, high light efficiency. The advantages of high color rendering are widely used in roads, tunnels, bridges, stadiums, exhibition venues, etc. It also means that the working stability of the electrodeless lamp is greatly improved. Under this background, the paper analyzes and studies the influencing factors of the light efficiency of the electrode free lamp, and tries to find a way to improve the light efficiency of the lamp by studying the temperature of the bubble. The electrodeless lamp uses the coupler to couple the electromagnetic field of the high frequency generator into the bubble body in an inductive way, so that the gas avalanche in the bubble is ionized, and the plasma excites the phosphor to emit light. The distribution state of plasma directly affects the light efficiency. The main work in this paper is as follows: 1) by analyzing the influence of temperature on the stability of the magnetic coupler, it is found that the performance of the coupler is relatively balanced in the range of 10.C to 125.C. And in order to deeply study the modeling and simulation of coupler electromagnetic field by using MATLAB in this paper, a large number of orthogonal experiments. 2) the light efficiency measuring device, which is brought by different parameters, is eliminated. According to the requirements of the measurement, the collection of light efficiency values at different positions of the bubble body is realized, and a light efficiency measuring device is designed, which is easy to carry and has high measurement accuracy. The device is calibrated. The determination of the temperature measurement system is completed, and the temperature values of different positions of the polar light bulb are collected. Through the experimental design, the best measuring scheme of the detection temperature and the light efficiency is determined. Finally, by analyzing and comparing the experimental data to determine how the temperature affects the light efficiency, and combining the temperature range obtained from the previous analysis of the magnetic coupler, it is determined that the temperature range of the highest light efficiency is 100 鈩，
