LED (Gobo) Projector Systems

TQ Engineering develops and manufactures projectors that can project text, logos, or other image content onto any surface. These projectors use so-called gobos, i.e. glass optics into which the desired image content is engraved with high resolution using various processes. Alternatively, projectors with microlens array technology are available, which are particularly advantageous in highly-tilted projection conditions or in tight installation spaces. For special requirements in pattern projection, we utilize diffractive optics and laser light sources.

Static logo and image projectors

Very small projectors are used in automotive lighting as door entry or mirror lights, projecting logos or other images into the car's surroundings. We develop optical and mechanical designs for this application, including the selection of suitable, automotive-certified LEDs.

Optical design for projectors

The challenge in the design of the projection optics is to achieve very good imaging properties with imaging errors and high contrast despite a small size and few, cost-effective lens elements.

MLA projection

TQ Engineering develops projection systems based on microlens array technology. Examples include projectors in automotive applications, such as in light carpets, as projectors of turn signal signals, or in interior lighting, for example for pattern projection onto vehicle interior parts or into the headliner. One advantage of using microlens array technology for projection is miniaturization, as installation space requirements in the automotive sector are often very demanding. The bottom image on the left shows a semi-dynamic projector of TQ. With this technology, the microlens array is divided into four segments, which are illuminated by four separate LEDs. This enables sequential control of the four individual images or patterns, thus achieving a dynamic-looking projection.
