Cool [DIY E92 M3] High-Power White Angel-Eye Lamp "KAIZEN Version"

Hello, M3 Fighter Pilots!!

Several months ago, I had introduced "High-Power White Angel-Eye" to you.

Now I improve it in order to get more brightness.
(As you know, KAIZEN means Japanese philosophy of continuous improvement.)

First of all, this is the result. My work has almost same brightness as genuine H8 halogen lamp.


There are two "Optcal Glass Pipe" as this diagram shown by tom@eas.

The left one guides the light to the left ring of the Outer Angel-Eye, and the right one guides the light to the right ring of the Outer Angel-Eye.

This is the genuine reflector of the Angel-Eye.

Check the direction of the light.

This is a plan of base plate.

Cut out stainless plate by laser cutting machine.

This is the High-Power LED "Luxeon K2 with TFFC Cool White" (LXK2-PWC4-0180). It has 250 Lumen (@1,500mA/3.85V).

It generates a great deal of heat. Therefore, it is necessary to implement a cooling system.

This is aluminum heat-sink and micro-fan for cooling the High-Power LED.


Assemble the micro-fan to the base plate.

Assemble the aluminum heat-sink to the base plate.

It has three High-Power LEDs. The center one is for the Inner Angel-Eye Ring, and the left and right one are for the Outer Angel-Eye Ring.

And It has a forced air cooling system by micro-fan which is usually used for CPU cooling.

The left one is the first version which I had made, and the right one is the KAIZEN version.

They has completely different shape.

Provide the power for checking its brightness. It has really "Cool White".

How dazzling it is!!

Install the KAIZEN version to the headlamp unit.

Close-up. The two High-Power LEDs on each side are just adjusted to the "Optcal Glass Pipe".

Compare the brightness of the Inner-Ring and the Outer-Ring. They has almost same brightness.

It is too difficult by several other products.

More information, please see here.
