Precision engineering

At our factory, dedicated to the development and production of Cinema Xenon lamps, we employ only the most highly qualified operators to produce all our short arc digital lamps. Together with expertise from our glass manufacturing and engineering specialists in other divisions of Philips, this ensures our Digital Cinema xenon lamps are manufactured to the highest quality.

All our lamps are US-made with the utmost precision, employing the latest technologies and techniques. From the electrodes and connectors to clever sealing technologies, just ten to twelve specialists will be involved in the manufacture of a typical lamp. Each lamp is individually tested to check that it ignites properly and that its electrical characteristics meet the specifications. 100% Inspections are built into the manufacturing process at multiple stages to ensure its highest quality before it is released. Moreover, the latest vision systems are employed to provide active operator feedback to ensure complete uniformity. Extensive training and certification is required before our operators can produce digital cinema lamps.
Building lamp seal assembly. Multiple layers of glass with different expansion coefficients are built up under vision system guidance, to allow the seal to compensate for the difference in expansion rates between quartz and tungsten.


Lamp sealing process. The electrode assemblies are inserted into the lamp envelope and the quartz material is fused together to provide a strong, gas-tight seal.

The thickness of the electrode glass seal assemblies are 100% inspected using a high accuracy digital microscope, to ensure all assemblies are built within specification.

Lamp sealing process. The quartz glass is heated red hot during an annealing step to remove stress.

 

Installation of metal fittings on the end of the lamp. The metal fittings are unique to each model of digital and film projector and are held in place by compression rings. The dimension from the cathode end base and cathode tip is carefully controlled to ensure the cathode tip is in the focal point of the reflectors inside the projector.
