Light rings based on using LEDs with 850 to 880nm wavelengths offer a compact means to illuminate a given area with near-infra-red light.
The OPA80 Series and OPA83 Series from Optek Technology are available in a variety of ring LED Power Light sizes and configurations, and feature an optional ambient light sensing device to minimise current consumption during high ambient light conditions.
"The OPA80 and OPA83 Series light rings were designed to easily illuminate a specific area with infra-red light", LED Power Light says Roland Chapa, Vice President of Optek Technology's Assemblies Business Unit.
"With a variety of configurations and sizes, LED Power Light along with the option for reduced current consumption, the light rings are ideal for applications ranging from mood lighting to daylight security camera lighting".
Additional applications for the near-infra-red light rings include spot lighting, flash lighting and under-counter lighting.
The near-infra-red light ring series includes the OPA80 12V light ring with ambient light sensor; OPA81 12V light ring without sensor; OPA82 5V light ring with ambient light sensor;LED Power Light and OPA83 5V light ring without sensor.
LED quantities range from 10 to 24, depending on voltage rating and ring size.
LED types include surface mount devices, with a viewing angle of 100 degrees, as well as 3mm through-hole packages with viewing angles of 18 degrees.
The OPA80 and OPA83 Series light rings are available in either 850nm or 880nm centre wavelengths.
Typical forward voltage for each LED is 1.35V.
Reverse voltage per emitter is 2.0V, with a continuous forward current of 50mA and peak pulsed forward current of 1.0A at 1% duty cycle.
Operating temperature ranges from -40 to +85C.
Custom mounting, electrical, cabling and connectors are also available.
The light rings are RoHS-compliant.
