Daylight White Visible LED Backlighting Strips With 120° Component Beam Angle
Providing lighting designers with a high intensity, reliable and cost-effective backlighting solution, TT electronics OPTEK Technology has developed a new family of visible LED backlighting strips. Designated OPA775 and OPA776, the “Jacob’s Ladder” series of backlighting strips are offered with daylight white LEDs and designed specifically for illumination of small- and medium-size display applications where lighting intensity and reliability are imperative.
“UAdditional applications for the OPA775 and OPA776 LED backlighting strips include architectural accent lighting, under-counter lighting, media illumination and large channel letter lighting.
The OPA775 strips are designed for operation at 12V. Each OPA775 consists of one strip of 7.5” 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 consists of two strips of 7.5” FR-4 board with three LEDs on each strip and a jumper wire connecting 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” intervals.
