Projector Modded With LED

Introduction

I got given a Panasonic PT-AE500E projector as it was ‘broken’. As you have probably guessed, the only thing wrong with it was the bulb. Unfortunately the bulbs are ridiculously expensive which meant it was effectivly a write off.

So I decided to try and fit a super bright LED instead. I knew it would never be as bright as an original bulb, but it is fine for a dark room.

Design

• Panasonic PT-AE500E projector
• Athlon XP CPU Heat sink + fan
• Seoul P7 LED – D-bin (supposedly anyway!..)
• Seoul P7 star board
• 2.8A constant current driver
• 52mm Aspherical Lens
• Arctic Silver thermal paste (ebay)
• Lux meter (ebay)

I removed the oringal high voltage lamp board, and fit an old Dell 20v power supply into its place – its covered in bright yellow tape in the bottom pics.
