TASKLED - Smart LED drivers

home > products (H6Flex)

H6Flex (Hardware specifications/features):

• H6Flex V1.0 released (July 26 2010). Firmware updated to support Luminus -50 and -90 parts. (Sep 29 2010)
• Microcontroller based constant current buck regulator.
• Ships configured for 1400mA current limit.
• User menu reconfigurable to 1400mA/2000mA/2800mA/3000mA/3600mA/5000mA/5600mA/6000mA or 6600mA at any time. Note, the 3000mA and 6000mA available only on h6flex drivers shipped after Nov 16 2010.
• Current limit set in firmware.
• User programmable low voltage warning.
• Ships with UI-UNI2 firmware (see below).
• Non-volatile storage of brightness level.
• Draws <0.1mA when in 'sleep mode' (electronic off).
• High efficiency (> 90% when driving 3 or more Seoul P7 or Cree MC-E 4P configured LEDs at 2.8A).
• Very low headroom requirement (Vin - Vout) of 1V at 2.8A drive.
• Can drive up to 20V of series connected LEDs (from minimum input = (output voltage + 1V)).
• Input operates from 7V to 22V. Being a buck converter, input voltage must be greater than output voltage - see the H6Flex technical section (manual) for specific information. 5 li-ion cells MAX.
• Protected against reverse polarity connection (low loss FET), output open circuit and output short circuit.
• Board is 1.3" in diameter, 8.9mm or 0.35" thick (inductor is the high point). Components only on one side, bottom side is for attachment to a heatsink.

  Software, UI-UNI2 Firmware:

  The new UI-UNI2 firmware unifies the previous UIF, UIP and UIB2 firmware into a single release. This has the advantage of providing the user with a choice of 3 of the most popular TaskLED UI's in a single product. The user can configure via the menu system which of the UI's is active at any time. UIF and UIP also inherit the temperature sensing capability of UIB2 along with the new 3 level voltage monitoring capability.

  • Unification of UIF/UIP firmware with the UIB2 firmware.
  • 3 user configurable voltage trip points to set independent Medium, Low warning levels and Cutoff.
  • If an optional 3mm or 5mm status LED is connected, the user can configure the status LED to warn when the voltage reaches Medium (status LED lights constant) or Low (status LED flashes).
  • Temperature monitoring of driver board. If closely coupled with the light's body, it can be user configured to force the current output to reduce. Optional trip points of 50, 60, 70, 80, 90C or off.
  • UIB2: Bike optimized, Choice of 2 level (duomode), 3 level (trimode or threemode) or 5 level (multimode) operating modes.
  • UIF: 8 level dimming, fixed lighting use optimized..
  • UIP: 5 level dimming, flashlight use optimized. .
  • User selectable optional Force level (the level that the light will always turn back on).
  • Optional superlock that requires multiple clicks to turn the light on - prevents friends turning your light on accidentally.
  • UIB2: User selectable Strobe mode or Constant mode for day/dusk or night use.
  • Refer to the h6Flex technical section for the downloadable PDF manual.
