Optek Technology OPA775 and OPA776: LED-backlighting strips illuminate small and midsize displays
Jun 19 2009 12:00AM | Permalink |Comments (0) |
The OPA775 and the OPA776 LED-backlighting-strip series features white LEDs and suits illumination of small and midsize displays requiring lighting intensity and reliability. Operating at 12V, the OPA775 includes a strip of 7.5-in. FR-4 board with three LEDs with one to 30 strips connected per bus. The strips feature Zierick 1286T connectors, allowing the “Jacob’s ladder” construction, enabling 30 strips to draw a total of 3.75A current. The OPA776 backlighting strips meet the OPA775 performance at a 24V operation. An OPA776 comprises two 7.5-in- FR-4 board strips with three LEDs per strip and a jumper-wire connection. The strips come in sets of 60 and draw a total current of 3.75A. The OPA775 and the OPA776 have a 50-lumen-per-strip luminous flux, with a 125-mA drive current to each LED. The vendor crimps the bus wires during manufacturing and spaces the LED strips at 6-in. intervals. Prices for the OPA775 backlighting-ladder-strip series range from $5.58 to $5.70 (1000); prices for the OPA776series range from $10.85 to $11.18 (1000).
