Light Dependent Resistors: Introduction

  • Light dependent resistors (LDR), also known as photoresistor, is an electronic component that responds to light. The light rays drop on the light dependent resistor, and the resistance is changed immediately.
  • Light dependent resistors are made up of light-sensitive materials such as cadmium sulfide (CdS), cadmium selenide (CdSe), lead sulfide (PbS), and indium antimonide (InS).
  • The working principle of light dependent resistors is photoconductivity, which is nothing but an optical phenomenon. When light is absorbed by the LDR material, the conductivity of the material reduces.

Rise in Demand in Street Lights

  • By application, the street lights segment is expected to be the fastest growing segment of the global light dependent resistors market during the forecast period.
  • The lightening-up of highways is done through HID lamps; but, the energy consumption of these lights is high and they lack a particular mechanism to turn on/off the lights from sunrise to sunset. Governments of many developed and developing countries are extensively using the alternative method over HID lamps, i.e. they have started implementing LDR power conserving of intensity controlled street lights to overcome the high energy consumption problem.
  • Moreover, light dependent resistors have less power consumption, and the life span of these lights is more compared to conventional HID lamps, which is also likely to boost the demand for light dependent resistors during the forecast period across the globe.
  • Furthermore, LDR lights have several advantages. They are highly sensitive, simple & small devices, easily used, and inexpensive. Their light-dark resistance ratio is high, and the connection is simple.
  • One of the major restraints of the global light dependent resistor market is the low-temperature stability. LDR provides incorrect results once the working temperature alters.

Asia Pacific to Lead the Light Dependent Resistors Market

  • In terms of region, the global light dependent resistors market can be divided into North America, Europe, Asia Pacific, Middle East & Africa, and South America.
  • The Asia Pacific light dependent resistors market is expected to see highest growth throughout the forecast period due to the rising use of light dependent resistors in electronic applications in the region.
  • Moreover, the governments of major Asian countries such as China, Japan, South Korea, Australia, India, and Singapore are focusing on upgrading their public infrastructure such as street lights which is likely to propel the growth of the light dependent resistors market during the forecast period.
  • Large number of light dependent resistor manufacturers are located in the Asia Pacific region, which also boosts the demand for light dependent resistors in the region.
  • The market in North America and Europe is expected to expand at a substantial rate during the forecast period due to the demand for light dependent resistors from the regions.
  • On the other hand, the market in Middle East & Africa, and South America is estimated to expand at a moderate pace during the forecast period.
