Digital Projection

The development of systems for projecting static or dynamic image content is one of our core technology areas. Digitally variable light distributions lead to new lighting functions or enhanced customer benefits in many applications, such as high-resolution headlights in automotive lighting or projectors for displaying logos or communication content.
Fields of application
  • High-resolution automotive headlight modules
  • Door or side mirror projectors
  • Projection of advertising content
  • Digital lighting functions for stage/effect lighting
Services
  • Optical design of projection optics
  • System development of projection units
  • Consulting/conception of digital imager technologies
  • Use of the latest pixel LED technologies

Near-Field Projection with DLP

For ambient or near-field projections in automotive lighting, not only static projections are desired, but also dynamically changing image content, such as light carpet-like patterns, messages, or short video sequences. Depending on the desired installation location in the vehicle, we are developing projection systems with digital imagers such as DLP® technology from Texas Instruments or LCOS imagers.

DLP Headlight Modules

Automotive headlight systems have undergone a number of profound changes, thanks to recent technological advances. For example, in the development of adaptive headlight systems (ADB), the high beam is automatically switched on and off depending on lighting conditions and traffic, or masked in specific areas of the light distribution. DLP® technology is used for very high-resolution headlight systems. The image on the left shows a DLP® module that we have developed for headlights. This module can generate complex light distributions with a resolution of over 1.3 million pixels and a total luminous flux of more than 1000 lm.

Projection using Phase Modulation

Texas Instruments' PLM (Phase Light Modulator) is a technology based on the well-known DLP (Digital Light Processing) technology, but instead of tilting the micromirrors, vertical movement of the mirror elements is possible. This allows for digital phase modulation of the light. Potential applications include projection, adaptive optics, and beam steering. As a design house partner of Texas Instruments, TQ Engineering supports customers in the concept development and implementation of PLM-based systems by developing the necessary components for the PLM system, such as the laser systems, the optics system, and the control system.

Projector Lights for Industrial Applications

Industrial applications often require robust and bright projection systems that can project patterns or signals from small installation spaces. Possible applications include projections on surfaces that warn of hazardous areas, provide user instructions, or display the human-machine interface (HMI). This is particularly useful when conventional displays cannot be used in the application environment.
TQ Engineering GmbH supports customers in system development as well as in the provision and production of projector systems, for example for robot systems or in logistics applications.
