I recently bought part to build an LED Projector and made some mistakes and bought all the LED parts individually. When I got the driver, the cheapest one available with Amazon prime for the 50 Watt LED I ordered came with a chip LED. Here here are the specifications
GLW Waterproof 50W led Driver Power Supply + 50W LED Chip Bulb Energy Saving For DIY Cold White
Type of Bulb: LED
Wattage: 50 watts
Incandescent equivalent: 375 watts
Color Temperature: 6000 Kelvin
Light Output: 3500 Lumens
Now, the chip I got with it is a weird design, and much, much brighter than the 4,000 Lumen 50 Watt chip I ordered on its own. However, as far as the individual LED's, it has 70 of them, 10x7.. instead of 10x5. So, is this a 70 watt? The driver I am using with it is:
Led driver
=^_^= input: AC 85-265V
=^_^= outputC:36V
=^_^= current£º1500mA
=^_^= Max power supply£º50W
I am curious if I get a 70 watt driver, if the brightness will be increased? Right now, I am not getting any light on the wall past 4 feet with the 50 watt, and that is while using a 44mm lens & 50 mm collimator reflector on the LED. I have a innolux 7" 1280x800 LCD for a raspberry pi I am using, and then 2- 240mm focal rigid 'acryllic 1mm page magnifier fresnels, and another 2 flimsy paper thick fresnel page magnifiers at about 220 mm Focal that I can mix and match, along with a Kodak Ektanar 100-150mm 5 inch F: 3.5 Slide projector lens for a Carousel 650 slide projector. It does not appear as though this kodak projector lens will fit the light cne from any of the fresnels, even if I double them.
Does this seem right, in terms of light output forcing me be within 3 feet of the wall, and being dim even then? That is with the LCD brightness turned all the way up, and it has no other film on it or anything,.. Or should I upgrade to a 100 Watt LED? Any recommendations on the lenses? I would like to get a 80-100" screen at about 3500 mm, though with these fresnel lenses, I think I am stuck at a 170" screen.How much light loss does a fresnel cause? Any tips would be great!
Attached is picture of the LED am trying to identify the wattage on.
