The key features and advantages of laser-phosphor technology
The number of projectors using laser-phosphor technology is growing at a fast pace. However, very little is known about the benefits of laser-phosphor technology within the general population. Here, we break it down, and show you where it's best to use laser-phosphor light.

So what is it exactly? The key difference between a standard laser and a laser-phosphor is the light it emits. With a laser, it emits red, green and blue light. This is then combined into one and passed through an optical diffuser. It's this light that's used to illuminate and produce the image.

With a laser-phosphor, the projector light is different in that it uses just one blue laser. This is then diffused and used to illuminate the DLP chip. It's also used to energise a phosphor wheel, which emits yellow light. This then divides into blue and green, which also illuminates the DLP chip.

There are many advantages to using a laser-phosphor light source. The primary reason is that brightness is of a higher consistency than most lamp-based projectors. This is due to normal lamp projectors decaying over time. This leads to the next advantage. Because laser-phosphor light does not need bulbs, maintenance is kept to a minimum and additional costs after purchase are kept low.

Other benefits include the fact that operating a laser-phosphor projector is quieter due to its high efficiency and therefore does not require cooling. It also benefits from a solid state light engine, which the projector can use in unusual positions.

Due to these advantages, the use of laser-phosphor projectors are ideal for university lecture rooms, school halls and museums, or areas where the projector's use will be much longer in duration than normal.

ProjectorPoint offers a number of laser-phosphor, including the ZU650.
