  • In the initial UHP lamp development stage, Philips and Osram took a lead, and focused on AC (alternate current) technology and has cross patent sharing with each other. As a result, Japanese companies focuses on DC (direct current) technology to bypass European patents.

Counterfeits

Manufacturers mostly in China have been reported to be making inferior counterfeit lamps. In the UK, one lamp distributor was prosecuted for supplying counterfeit Epson lamps that seriously damaged an Epson projector in Germany.

As an increasing number of counterfeit lamps are being sold, projector manufacturers, such as Optoma and Epson stress the importance of authentic and original lamps. Optoma and Epson hold the biggest projector market share in DLP and LCD respectively.

Devices using UHP lamps

  • Samsung DLP rear-projection TV sets.
  • Sony LCD rear-projection TV sets.
  • Most digital projectors manufactured post 2001 (except LED projectors)
  • Olympus ILP-2 high-intensity light source
  • Mitsubishi DLP projection televisions
