New 100W LED Array Headlight?

Postby c0nsumer » April 17th, 2009, 9:35 am

To those of you interested in DIY electronics, check out this write-up on a 100W LED array purchased via eBay. I'm really really tempted to work one of these into a bike headlight.

Imaging riding single track bringing along your own streetlight. That could be all sorts of fun.

This looks real good for lighting up the trail and starting your camp fire all with one unit. All it needs is a battery with a hub charger or wheel charger for recharging and maybe a car charger. Be careful it doesn't start the woods on fire if you crash and don't get up for a wile :shock: The pile of leafs should start up real easy!!!!!! On the plus side the extra heat could be a plus if you riding in the winter for a heat generator air stream for the Moose mittens. Neat Idea needs work but with great up side. :lol: :lol: :lol:

I was ooohing and ahhhing, but got lost right about here:

Reverse Voltage:5.0 V, DC Forward Voltage: Typical: 32 V Max: 36V
DC Forward Current: Typical: 3000mA Max: 3500mA, Viewing Angle:160 degree
Lead Soldering Temp:260?C for 5 seconds
Size of led: 40mm X 46mm
led emitter size: 21.5mm X 21.5mm Viewing Angle:160 *Absolute Maximum Ratings at Ta=25?C:
Power Dissipation
Pd 125 Watt
Peak Forward Current
(1/10 Duty Cycle,0.1ms Pulse Width) IF(peak) 3500 mA
Continuous Forward Current IF 3000 mA
LED junction temperature JT 85 ?C
Reverse Voltage VR 5 V
Operating temperature range
Topr -20?C to + 80?C
Storage Temperature Range
Tstg -30?C to + 100?C
*Electrical/Optical Characteristics at Ta=25?C:
Parameter Symbol Test Condition
Min. Typ. Max. Unit
Luminous flux ? IF=3000mA 6400 - 7400 Lumens
Viewing Angle 2?1/2 IF=3000mA 160 deg
Forward Voltage VF IF=3000mA 32 - 36 V
Reverse Current IR VR=5V 100uA
Color Rendering Index Calculation Spm X 0.280 - 0.340
Spm Y 0.280 - 0.340
Correspondingly CCT IF=1500mA 5500 6500 7500 K

It's nice tho!

Excluding the power requirements, that's a *beep* of a lot of heat to sink.

The names probably wrong but the guy I was thinking about was a large viking looking kind of guy with a hammer and lighting bolt to launch. It was a comic book superhero.
