Some of these high spec led projectors are costing less than 1k with 3000 to 5000 lumens.
Led projector lamp circuit.
This project shows the designing of a game using leds.
In last 2 months led projectors have bridged the gap to laser in terms of lumens and image quality.
White leds for lighting should be used but you can specify the color of the led suit your mood.

The game zeppeline is named after its inverter.

Led projector lamp v 1 0.
If you had a 1 000 lamp based projector and a 1 000 led or laser projector the uhp lamp projector is going to be brighter.
Once the management circuits are satisfied that the lamp has lit and the arc is stable they will send the required lamp ok signal to the main board.
There are lots of affordable led based projectors available today but.
If you take care of projector lamps and let them cool properly.
Here is project showing diy led projector.
Last year i came across a cheap toshiba tlp t70m projector on some e bay wanna be site over here in romania.
The biggest advantage is the price.
My first video projector.
High power 3 led bicycle light.
As an arc lamp they are ignited by the ballast module and the current carefully monitored by ballast management circuits.
It had no lamp at all but other than that it was operating properly or so the salesman told me.
A high power bicycle light is designed here.
You might have already used light dimmers but this led lamp dimmer circuit is a very simple circuit where a bunch of leds continuously change its intensity.
Draws 10ma 20ma to the leds 330ohm 160ohm would suggest that attracts circuit for leds is working with 12v circuit by changing the value of the resistor the circuit can operate at lower voltages.
But since it s nearly impossible to get original focus brightness and contrast with this homemade led solution it would be simpler faster and cheaper to fit a 240 watt 3500 lumens bulb lamp from osram or philips used on many modern projectors for usd 30 00 on ebay probably keeping all the original projector circuits and giving a nice.
Laser being 3 to 4 times more expensive as these are produced by the big boys.
