Laser vs led projector8/19/2023 In 2021, Norxe announced the P2 projector, a compact projector with pure RGB laser light source, aimed at niche markets such as simulation, control rooms, scientific visualisation and planetariums. Until recently, the pure RGB projectors have been very large in size, very bright (typically 30,000 lumens and up) and very expensive. The first commercial pure RGB laser projectors were introduced in 2016, targeted at the digital cinema market. A pure RGB laser light source is also solid-state. What are laser and laser phosphor light sources?Īnother new light source compared to the lamps, are laser and laser phosphor light sources. Some LED-based projectors are designed to run up to 25,000 hours before service and the LED light source has a lifespan of 50,000 hours or even more.Ĭombining LED with DLP™ projection systems, LEDs enabled the projector manufacturers to remove the color wheels, eliminating a weakness in the DLP one-chip projectors. LED technology is perfectly suited for heavy duty use applications, where longevity and reduced need for maintenance are critical factors. With recent developments in LED technology, you find projectors with up to 5,000 lumens using the high-lumen-density ColorSpark™ HLD LED technology from Signify/Philips. The negative with LED compared to other light sources is that it initially had very low brightness output, and the first native LED projector in the market had no more than 400 lumens. Compared to other light sources, LED has a number of advantages, including long lifetime, small size, fast on-off switching and low energy consumption. The light-emitting diode (LED) is a semiconductor light source. What is a LED (light-emitting diode) light source? In normal use, the brightness output of the lamp is reduced to about 50% of the initial brightness after 1000-1200 hours use. A UHP lamp found in a professional projector has a lifespan of 2,000-2,500 hours and a warranty of 500 hours or 90 days. In this lamp space, you find lamps with up to 4,000-5,000 hours’ lifespan, but these lamps are typically not used in professional projectors. Today, the product is more or less the same, but with incremental improvements over time (better drivers, electronics). The concept of the UHP lamp is a high-pressure mercury arc lamp that was introduced in 1994. One of the most common lamp types is the The ultra-high-performance lamp (UHP, a trademark of Signity, a spin-off of Philips). We will look at some of the different lamps, RGB laser, laser phosphor and LED in this part. Since the introduction of mainstream laser projectors in 2016 and LED projectors some years earlier, the most common light source is still lamps. What are the most common light sources in projection? These are benefits that are appreciated in many applications, such as simulator systems, control rooms, planetariums, scientific visualization and with stringent up-time requirements. (of a device) making use of the electronic properties of solid semiconductors (as opposed to valves).Ī solid-state light source is generally more rugged and provides a longer lifespan and reduced need for maintenance, while also providing other benefits such as a wide and saturated color-gamut or in larger pure RGB laser projectors – incredible brightness levels. A UHP lamp that uses vaporized mercury in an arc design to create the brightness is not considered solid state. For a light source such as LED, it is based on a semiconductor system. Solid-state refers to electronic components, devices and systems without moving parts. What are the benefits of solid-state light source.Introduction to different types of light sources, such as lamps, laser, laser phosphor and LED.What is the definition of solid-state when it comes to projection?.In this article we will cover the following topics: Today, many projectors are using a solid-state light source such as LED and laser, which gives a lot of benefits, compared to the more traditionally used lamps. The choice of light source highly impacts cost and service requirements. One of the most important components in a projector is the light source.
