E-TORL Projector Technology

Although projector technology has brought outstanding imaging to the home, classroom, boardroom and auditorium, Epson continues to push the boundaries of visual imaging, creating better products with less light wastage that are both energy and cost-efficient.

With this in mind, a new alternative – the E-TORL lamp - has been developed and produced by Epson, that brings projector technology to a whole new level.

So how does the E-TORL lamp actually work, and what makes it an improvement on previous projector technologies?

Here’s the science bit

The innovative design of our E-TORL lamp means that it is smaller, brighter, more efficient and runs cooler than previous lamp designs.

As illustrated in the comparison image, light emitted from the burner’s electrodes hits the reflector and is reflected into the optic lenses to pass on to the LCD panels (3x) for projection. While the parabola-shaped reflector on an ordinary lamp usually leaks out and wastes a significant portion of the lamp’s light rather than reflecting it into the optical train, this is no longer an issue with E-TORL.

With this new design, we have replaced the parabolic reflector with an elliptical reflector, combined with a twin sub-reflector unit which gathers light that would otherwise be lost, then redirects it back to the rear elliptical reflector and into the optics.

This innovative technology – together with an optimised system of mirrors – enables you to reap the advantages of brighter images from a lower wattage bulb while using far less power.

This major update in the design has achieved a 20% improvement in efficiency making the light output brighter and reducing the waste heat that resulted from lost light in the ordinary lamp design.

Apart from the obvious advantage of clearer, sharper projector images thanks to the increased brightness with 2500 lumens, what are the other key benefits that make an Epson projector with an E-TORL lamp the projector of choice?

• Shrinking optics equal shrinking costs, as a reduction in the overall size of the projector also means a reduction in purchase and running costs
• Less power consumption, less heat emitted
• Longer lamp life, quieter operation
• The smaller size is great for business use as it can easily be transported between meetings and presentations
• Home users will also benefit as the smaller unit can be moved from room to room with minimal inconvenience

So all in all, the Epson E-TORL lamp is the standard of innovation that not only ensures we remain ahead of the competition when it comes to developing projector technology, but continue to provide our customers with outstanding products that deliver on every level.
