IR illuminator makers adopt LED arrays, IR lasers

Modular designs complement diversification of light sources used. Makers continue to improve power supply and heat dissipation attributes.


  • Shift to LED arrays, IR lasers: Models with IR LED arrays are on the rise because of better luminous efficiency and condenser performance, and longer life span. For long-distance surveillance, IR lasers are preferred.
  • Modular formats emphasized: The latest releases come in modular configurations to allow flexibility in design parameters using the same mold. Suppliers employ IR LEDs with different radiant power and viewing angles to optimize illumination and match IR ranges. They also continue to broaden selections based on mounting to suit various setups.
  • High reliability & long operating life: To ensure consistent product performance, companies utilize imported LED chips and lasers for pricier versions. They are improving power supply and thermal properties further via PWM circuits and heat sinks. Materials with high thermal conductivity and air-cooled devices will be gradually used in upscale variants.
  • Price projection: Quotes will go down with LED chip costs, which are anticipated to decrease 15 to 25 percent in coming months after dropping by about 30 percent in 2011.
