摘 要: 研究了荧光粉激光显示光学系统中关于混合白光色坐标的计算方法以及色坐标、色温、光通量随荧光粉比例变化的规律。蓝色激光激发红色、绿色、黄色各单色荧光粉轮,运用积分球采集光谱,得到各单色荧光的色坐标。根据单色光色坐标,采用混合白光色坐标计算方法模拟出蓝光通过不同角度比例组成的色轮所形成的白光的色坐标,模拟结果与实验测量数据误差为±0.4%. 结果表明:增加色轮上镂空灰色部分(蓝色)比例,白光色坐标会减小;增加黄色荧光粉比例能够提高白光光通量,同时也会引起色温减小。可根据不同荧光粉比例的色轮,获取不同色坐标、色温和光通量的白光光源。
关 键 词: 光学;激光显示;荧光粉色轮;色坐标;色温

Abstract: In this paper, we study the laser optics display of fluorescent powder calculation method of the color coordinate of mixed white light and the coordinates, color temperature and flux white with the change of proportion of fluorescence powder. Blue laser motivated monochromatic color wheel of red green and yellow, we use integrating sphere to collect spectra, get color coordinates of each monochromatic fluorescent. According to the single color coordinate, we use the method of color coordinate on color mixing to simulate the color coordinate about different proportion of fluorescence. The simulation results with the experimental measurement data error is �.4%. The results showed that increasing the ratio of gray spaces (blue), the color coordinate of white light will be reduced. Increasing the ratio of yellow fluorescent, the luminous flux will be raised, while the color temperature decreases. We can obtain various of white light source with different color coordinates, color temperatures and luminous flux according to the different color wheel of different proportion of fluorescence.
Key words: optics; laser display; color wheel of fluorescence; color coordinate; color temperature
