摘要
超高压汞灯(UHP)是液晶投影仪和液晶背投电视的光源,具有光效高、寿命长、光谱好和接近理想的点光源等特点,在DLP,LCD,LCOS等各种液晶投影显示系统中应用广泛。从安全使用的角度介绍了UHP灯芯和灯碗结构特点和设计要求,对UHP灯光谱特征以及延长UHP灯使用寿命的关键措施进行了讨论,并强调了合理的电气工作条件的重要性。
Ultra High Power（UHP） is the light source of Liquid Crystal Display（LCD） projectors and LCD back- projection television. The UHP light source has the advantages of high luminescent efficiency, long lifetime, good spectrum and low caloric value and so on,and has been widely used in DLP,LCD and LCOS. For the sake of safety,the introduction is made of the structural features and demanded design of UHP＇s lamp mount and lamp bowls. The discussion is made on the key measurement for the characteristics of light spectrum and long life in use. The further emphasis is laid on the importance of reasonable electric condition.
