A light or image projector is a top class module that includes an optical device for a targeted projection straight from a light source. It is used to project an image (or if you like moving images) onto a certain surface, commonly a projection screen or whiteboard. In this application, however, I assembled a small light projector and embedded a 3D printed color surface into it. After that, I’ve been doing some trial & error work in various settings. Come and see how wonderful this works out when the light ‘paints’ various objects and surfaces in my backyard.
Light Projection: The Principles
The idea behind most projector lights is creating an image or concentrated hot spot by shining the light through a small transparent lens, for example to accentuate an object. The narrower the beam, the more precise and focussed the projection will be. LED lighting projectors are becoming more and more popular for use in a variety of applications. Emerging LED technology is now being applied onto a wide range of products, both for functional and decorative lighting purposes. Its durability and stability (incl. shockproofness) makes it an attractive lighting design option.
Projector Types and Use
The most common type of projector we are all aware of is the ‘video projector’: A digital replacement for the earlier types of projectors such as overhead- or slide projectors. These earlier types of projectors were mostly replaced with digital video projectors throughout the 1990s and early 2000s (decade), but old analog projectors are still used at some places, for example at my grandparents’ home.
LED Lighting Projectors are on the Rise
The latest generations of projectors are handheld projectors that use lasers or LEDs to project images, such as the device I used. A disadvantage is that its projections are hard to see if there is too much ambient light, so I limited this trial & error session to a fully dark garden environment only.
This blog is just another proof of evidence how light can enrich your ambiance in a functional or decorative way and turn unintresting or indistinct materials into living surfaces!
