Using the raw OHP, without replacing the light engine will produce dim results especailly when using smaller lcd. The OHP lenses is more suited for 15 -13 inch lcd.

thanks for the info sir! so would it work fine if i just replace the bulb? or would i be better off starting from scratch? tia

Ok using 7 inch lcd,

You can still use the following parts from OHP

1. Projection lens- assuming it is a triplet lens
2. Top fresnel lens
3. Reflector
4. fans and switches

You need to buy
1. Bottom fresnel lens with lower focal length
2.Condenser lens
3. SHort arc metal halide bulb
4. ballast capacitor and ignitor

this will cost you about 5t+. Expect a very good result as long as the lcd is of good quality.

If you will use 10-15 inch lcd size

you will just buy the following
1. short arc bulb
2, ballast capacitor and ignitor
cost baout 4T pesos

Sa 1080p, bumili ka na talaga ng screen. Sayang naman kung kita mo yung mga scratches sa wall while viewing in HD.

Sa DIY PJ's niyo, complete interface rin? Kaya HDMI, component, Svideo, etc?

AlvinladeN · « **Reply #82 on:** Mar 27, 2010 at 08:24 AM »

^sa 15inch 1200p ko DVI (HDCP) and VGA lang, sa 7inch ko VGA and S-video. meron namang nabibiling external tv box for component and composite connection but for me useless na.

Replace the 250w metal halide HSD bulb with 100w LED

Still using the same 7 inch lcd and lenses.

wow 100 watts na lang!

hertzblaster · « **Reply #85 on:** Aug 04, 2010 at 09:38 AM »

And its cooler than commercial projector using bulbs.

Other than savings on lamp power cost,

Aircon cost will also be lower kung aircon ang room mo.

50,000 hours Led life.

Sir, YGPM.

markcrenz · « **Reply #87 on:** Aug 04, 2010 at 10:17 AM »

sir hertz if i can mechanically fit an LED lamp in an existing commercial projector wala bang problema sa electrical/electronics side?

hertzblaster · « **Reply #88 on:** Aug 04, 2010 at 04:04 PM »

100w led will not fit. The LED requires a very efficient heatsink. May fan pa sa likod ng heatsink sa picture above. That is why yung CDRKing uses only 30w LED because lower wattage means lower heatsink size.

30watts led output is only 2000 lumens while the 100w version has 7000 lumens so now I can easily predict the brightness of cdrking led projector.
