Laser Projectors

Laser Projector Guide.

More and more projectors are entering the market using lamp free light sources. These type of projectors are known as solid state light sources, SSL or just Laser Projectors. SSL or laser projectors are light producing systems made up of either LED devices or Laser

So what does this mean? Well, laser projectors are projectors with light producing systems made up of either LED devices or laser diodes. Changing the light source in this way brings about a lot of benefits. Light produced with SSL systems inherently has a longer and steadier brightness that decreases at a much slower pace over time than that of lamp based systems. As such, this technology offers high image quality while providing an operating life span that far exceeds traditional lamp projectors.

It’s an increasingly popular choice of technology for manufacturers and consumers alike and well worth understanding if you’re in the market for a new projector.

Benefits of Laser Projectors (Solid Light Source).

There are a huge number of benefits associated with laser projectors, including:
  • Lower maintenance costs
  • Consistent light output
  • Longer life span
  • Constant color rendition
  • Up to and including 24x7 operation
  • Lower brightness decline during life time
  • Better brightness uniformity
  • Higher reliability
  • Higher contrast
  • Wider color gamut
  • Lower energy consumption and lower thermal emission
  • Instant on/off capability, flexible brightness adjustment (20-100%)
  • Mercury free
  • The Main Laser (SSL) Technologies.

    LED Light Source

    LED was the first solid-state projector type to be commercialised around eight years ago but it is limited in light output and mainly used in specialty markets. Specifically, LED systems use only red, green and blue LEDs, which reduces the quality of the resulting images. Benefits associated with LED light sources include the small projector chassis and up to 20,000 hour life span. However, LED projectors have limited brightness capability, limited colour reproduction of yellows and a limited maximum screen size.

    Laser Phosphor Light Source (DLP Display).

    Laser phosphor illumination uses a blue laser diode as the light source instead of a high intensity discharge (HID) lamp. To generate the three primary colours, the laser diode shines laser light onto a phosphor wheel to create yellow light, while blue laser light passes through an opening in the phosphor wheel. The projector then sends the yellow light through a colour wheel to generate red and green, while the blue laser light passes through a diffusion window. These red, green and blue colours are then directed onto an imaging surface, such as a DLP chip, which directs the light through a lens and onto the projection screen.

    The main advantage of a laser phosphor projector is the long life of the illumination system – it will be in use for a long time before it the projector drops down to 50% brightness.

    As a lampless system, laser phosphor also eliminates the need for lamp and filter replacements, reducing the down time, maintenance and costs associated with lamp-based projectors. The long life and low maintenance of laser phosphor projectors also make this technology ideal for high-use settings like boardrooms, classrooms and location-based entertainment. 

    Certain manufacturers claim laser phosphor projectors provide “maintenance free” operation. Although it is true that laser phosphor illumination systems are solid state and so do not require any maintenance throughout their lifecycle, this only applies to the light engine. Laser- based projectors should still be subject to regular maintenance such as cleaning fans and lenses to maximise efficiency and performance. 

    In return for a little care and attention, your DLP display laser light source projector will deliver high brightness, true colours, large screen sizes and life span of up to 20,000 hours.

    Laser Phosphor Light Source (3LCD Display).

    In a laser phosphor light source projector, the projector's light engine uses blue laser as its light source, which excites a phosphorous material and, in turn, creates white light. The white light is then delivered to a 3LCD optical system, generating constant, vibrant RGB colour through a light splitting process. 

    Again, this results in high brightness levels, true colours, large screen sizes and an excellent life span of up to 20,000 hours.

    RGB Laser Light Source.

    Pure laser, also known as 3-Primary (3P) or RGB laser, generates light directly from three individual red, green and blue lasers. The primary benefit of a RGB laser system is light output while also achieving higher performance in other standard image quality parameters such as color gamut (This makes it possible to realise a color space that reaches the amazing level of colour reproduction in the BT2020 standard), contrast ratio and dynamic range when compared to standard lamp based systems. As such, RGB laser is ideal for large-scale applications and giant screen cinema

    Is a laser projector right for you?

    Excellent crisp, bright images, an impressively long life and reduced maintenance make laser projectors appealing. But if you’re not running a cinema, do you really need to invest in such advanced technology?

    It’s still not an essential step up to make, but there are a lot of benefits to be had from a laser projector, even in everyday usage scenarios.

    Laser projectors for business use

    Meeting rooms are dynamic environments requiring efficient technology that can go from standby to full working mode in seconds. Laser projectors allow businesses to stay productive and reduce interruptions, providing instant access to presentations and meeting notes. 

    In the long-term, laser projectors also benefit business environments by removing the need for costly lamp replacement, as well as reducing the need for down time during maintenance periods. In addition, laser projectors offer impressive brightness and improved quality of image, both of which help drive productivity in meeting room and office environments.

    Home Cinema Laser Projectors

    The introduction of laser projection technology to the cinema industry promised to offer a number of exciting benefits for both home cinema and theatre owners, and it certainly didn’t disappoint. 

    In contrast to traditional lamp-based cinema projectors, professional laser devices offer drastically increased on-screen light levels, a long lifespan of around 30,000 hours (or 8 years in standard cinema operation), and richer colours, for a more engaging and all-consuming cinema experience. 

    Already adopted by global names including IMAX, laser cinema technology is expected to go from strength to strength in this demanding industry. 

    The advancements in cinema laser projection have filtered down for home cinema projector users to enjoy too. Although manufacturers are still only delivering a small offering, laser home cinema projectors are likely to appeal to those seeking easy maintenance, low costs and an impressive life span.
