Sorry for bad english, translation is in Google.
I gathered me headlamp.
LEDs - 6 pcs. (XML, 4000K )
Body Material - D16T aluminum , milled from a single piece
Brightness - 4000 lumens , 50 watts.
- Site development, programming , MK AtMega-8A
- 3-channel driver , exposure zones : near (1-7 m) , medium ( 7-20 m) , the distal (20 -100m )
- Digital display on a 3- digit LED
- The state of the battery Percentage
- Adjust the brightness of the display
- The ability to quickly configure any combination of pairs of LEDs on any mode on the spot even drunk using the menu displayed on the LED display
- Flexible adjustment strobe ( brightness control , frequency) on any of the switch positions , you can eliminate all who do not like
- 3- way switch ( mode 3 ) and on / off button ( hold - enter the menu)
- Dipped in the case of working with middle or middle + further reduced to 60 % in order to avoid blinding itself
- Temperature control with a warning flashing on the display and then a smooth decrease brightness when cooled returns to the previous mode
- Set artful lens dazzle, with a power of 50% (low ) is not blind , it is very convenient for the parks with people.
Pleasantly surprised by the heat capacity .
Included in the basement ( 15 degrees Celsius) to a maximum of about 50 watts .
Waited 7-8 minutes , during which time she headlamp not more than 40 ( Celsius) degrees (arm feels barely warm).
Headlight rigidly fastened to the mother clutching steering through Thermopastes wheel itself also through the thermal grease on the takeaway and there pounds of aluminum.
I will say one thing, temperature control did nothing =) this construction probably impossible to overheat unless summer night 25 include 50 watts per hour.
History of creation.
I wanted to collect the spotlight for electric bicycles with a claim to the correct light distribution and neosleplenie counter . Light distribution scheme vidilas about this:
I was looking for tilt angles empirically gathered some semblance stand.
Each diode can be twisted and recorded separately.
Half an hour for me to find the best angles, recorded, measured.
The figures are as follows: 2 long lens (0, 3 degrees), the central zone 2 of the lens (6, 9 degrees), the lens 2 near zone (12, 14).
Next began making attachment to removal, the driver decided to hide in the stem by making a hole in it for the display.
To test fixture made of foam =)
Dimensions approached, made of aluminum.
Cut the cost of the machine, cutter 0.4 mm, skirting all vias.
Collected fee, tracks restored postings.
Now the board is placed in the stem.
I bought a new bike.
Takeaway was there quite another fee to remove it did not work.
Painted house driver. Gets Slimmer, could be removed under the tap, but where to put the display then I do not know.
Let it be bulky, more metal will be heated longer.
Here's what happened.
И фото на велосипеде.
Пусть это большой, но 50 Вт меньше, я не видел.
Дождь на улице, ожидая сухую погоду будет bimshoty.
