Comparison of IRC technology with the existing LDR technology

LDR Technology

  • A separate window is given for LDR sensor to receive light
  • Accumulation of dust and other materials (leaf, moisture etc) on the window may hinder the sensing capability of LDR. As a result, the bulb/street light glows continuously (24 hrs) causing the energy loss and thus reduce its life span
  • Short life
  • The LDR sensor can detect all kind of light from the nearby sources (tube light, moon light, neon lamp light and lightning, etc.) and this may seriously affect the proper functioning of the bulb/streetlight
  • Narrow spectral response
  • LDRs are highly inaccurate with high response time:
    On the receipt of the light from other sources, the resistance varies continuously in photo resistor and are rugged in nature. If the atmosphere temperature changes, LDR will give inaccurate result. So, the LDRs are highly inaccurate with high response time
  • Do not work well in the cloudy season

IRC Technology

  • No separate window is given for the sensor. The entire sensing circuit is well enclosed inside the IRC bulb/streetlight/holder/kit
  • Since the infrared rays pass through the dust, leaf or the moisture the deposition of such obstacles on the sensor do not affect the functioning of the bulb/streetlight/holder
  • Long life
  • It detects infrared rays only. No other lights except infrared rays can affect its functioning
  • Wide spectral response
  • High accuracy and fast response:
    Since its operation is strictly controlled by the infrared rays from the sun, the IRC technology has high accuracy and fast response
  • Works well in the cloudy season too

Comparison of IRC Technology with the Existing
Timer Circuit Technology

Timer Circuit Technology

  • A timer circuit required for its operation
  • Complicated design
  • Highly undesirable in the cloudy season and in the winter season too
  • Not applicable in the countries/place where the day/night is shorter/longer.

IRC Technology

  • No need to setting up a scheduled timer for the lights. The lights are ON only when the density of infrared rays from the sun is low and are OFF when the density of infrared rays from the sun is high
  • Simple Design
  • Works well in the cloudy season and in the winter season too
  • Applicable anywhere and even in the countries where the day/night is shorter/longer
