TT electronics Optek Technology (Carrollton, TX) has developed OPA775 and OPA776, a new family of visible LED backlighting strips. Designated the “Jacob’s Ladder” series, the backlighting strips are offered with daylight white LEDs and designed specifically for illumination of small- and medium-size display applications that demand lighting intensity and reliability. One power supply and one connector can be used for the entire configuration, whether it comprises one or multiple backlighting strips. Also, the 120° light beam angle is suitable for small- or medium-size areas, such as lightboxes and POS displays. Other applications include architectural accent lighting, under-counter lighting, media illumination and large, channel-letter lighting.

The OPA775 strips, which are designed for operation at 12, comprise one strip of 7.5-in. FR-4 board with three LEDs. One to 30 strips may be connected per buss. The OPA775 features Zierick 1286T connectors, enabling the construction of the “Jacob’s Ladder.” The total current drawn by 30 strips is 3.75A, and the strips are shipped in sets of 30.

The OPA776 backlighting strips match the performance of the OPA775 devices but are operated at 24V. One OPA776 entails two strips of 7.5-in. FR-4 board with three LEDs on each strip; a jumper wire connects them. The OPA776 strips are shipped in sets of 60, and the total current drawn by 60 strips is 3.75A.

Luminous flux for both the OPA775 and OPA776 backlighting devices is 50 lumens per strip, with a drive current to each LED of 125mA. OPTEK crimps the buss wires at manufacturing and spaces the LED strips at 6-in. intervals.
