Simulation training for LED lighting White

Introduction: Since the invention of the beginning of large-scale high-resolution projection technology has become the main image display technology. Over the years, Projector The development of computer graphics and video sources to keep pace with the progress and follow the higher resolution and larger screen size trends.

However, in some applications often require a larger projection area on the higher pixel density, which no single fixed focus projector is not available, especially simulation training (S & T), The training process often required to achieve a wide field of view, "the naked eye limiting resolution" of the target. The best way to achieve the above application is multi-projector array arranged as a projection, and then projected by each projector's image stitching together to form a higher number of pixels in the composite image. Gained independence through the edge of the image can be spliced, and it can be integrated by the images overlap and the edge map obtained by the seamless whole.

Challenge Projector array to the image projection application brought many unique engineering challenges, which in the (different projector to project) contiguous surface on the edge of the image fusion is particularly evident. As a design and manufacture of equipment for array projection display old company, Christie? The projection equipment in turn based on cathode ray tube (CRT), liquid crystal on silicon, and DLP technology? Years, has been proposed to address these challenges specific solutions. [1]

ChristieTWIST will ChristieDLP projector deformation and integration module internal and external computer software running in the combination of image fusion process to resolve the multiple overlapping surfaces will focus on the matrix image of the geometry projection and precise stitching problems. ChristieAutoCal is able to meet the precise stitching and integration projector array calibration maintenance. ChristieAdvancedColor is to solve the display multi-screen array in the exact color matching. ChristieMotoBlend optical fusion of electric colors in dark scenes to maintain good contrast, while a different black level for integration, and high-speed simulation process caused by the human eye to track image smear and double as problem can be resolved through AccuFrame .

The next solution Projection arrays now the main challenge is the reliability of the projector orientation and flexibility, ease of installation of projectors and the use of performance after a certain time to maintain. All these will be the projector light source a great impact on performance.

Digital projectors typically use high-pressure gas discharge (HID) light exposure to one or more microdisplays. Today, under the lights usually based on high pressure xenon or mercury vapor discharge steam. As for the S & T array projector projector from analog (CRT and the light threshold type) evolved into digital, with the main form of solid-state integrated circuit components within the framework of the projector is also accounted for a growing ratio? including the microdisplay DLP technology. However, the light projector is still stubbornly maintain non-solid, until now too.

Solid-state light-emitting diode (LED) to replace the HID lamp appearance. As ChristieMatrixStIM projection system, as shown, it brings the operation and performance of the many obvious advantages, and can solve some of the existing projection array problem.

Speaking from the operation, LED's main advantage is high reliability and long life. For example, according to LED maker LuminusDevices company millions of hours of equipment based on actual use Test Obtained reliable data, we can predict, in projection applications, the standard operating conditions, which values life more than 80,000 hours.
