阿惠搞到一部绝佳大片,特意借了一部投影机,呼朋唤友同到他家去欣赏。在下也是其中之一哦。兴冲冲地赶了去,坐下一看不禁大失所望!什么绝佳大片?雾蒙蒙的一片,连小姐的特写脸蛋都瞧不清楚啊!“本来是好的嘛……”阿惠自言自语着,关闭了投影机,抱歉地对大家笑了笑说,“我在高清电视上试播画面特清晰锐利,连衣服的布纹都看得清清楚楚的……”那么问题一定出在投影机上了。问过投影机主才晓得,这台投影机还是2000年买的,平时用得多,灯泡老化得厉害,旱该换了,就是还没来得及去买。灯泡是投影机的唯一耗材,直接关系着投影图像的清晰度。目前,无论是哪种投影灯泡,都有一定的使用寿命。随着投影机工作时间的延长,其亮度会不断降低,投影的图像也就会越来越不清晰,当投影灯泡老化到一定程度时就必须更换了。不过,目前很多投影机产品为提高光源利用率,都配有良好的散热设计,以及其它一些手段,使灯泡的寿命有了较好的延续。
A Hui got a great blockbuster, specially borrowed a projector, Hupenghuanyou to his home to enjoy. In the next is one of them. Hing rush to catch up, sit down and can not help looking disappointed!

The bulb is the only consumables for the projector, directly related to the sharpness of the projected image. At present, no matter what kind of projection lamp, have a certain life. As the working hours of the projector increase, its brightness will continue to decrease, the projected image will be less and less clear, when the projection lamp aging to a certain extent, it must be replaced. However, at present, many projector products to improve the utilization of light, are equipped with a good thermal design, and other means to make the life of the lamp has been a better continuation.
