The Brighter the Better
LED, Lamp and Laser are the common used light sources for projectors. We provide every kind, to offer you the right projector for your needs.
LED (Light Emitting Diods) are very small and can be assigned to emit just one color (red, green or blue). With their small size, projectors can be made quite compact, but the downside is the weak light output.
A Lamp has a much higher light output than a LED. However, lamps still waste a lot of energy, even though only the primary colors are actually needed. By that they produce a lot of heat, necessitating the use of a fan to keep it cool.
So is a Laser (Light Amplification by Simulated Emission of Radiation) the best alternative? They provide a wider color gamut, have an increased light output and a longer source life. But as you can already imagine, the laser is the most expensive source of light.
