How is Development of Smart Cities Causing Boom of Global Light Sensor Market?

The increasing usage of consumer electronic devices is one of the major factors propelling the demand for light sensors across the world. In various consumer electronic devices such as smartphones and tablets, several features like automatic screen brightness control require the sensing of light. 1.4 billion smartphones were sold throughout the globe in 2019 and this number is expected to increase to 1.6 billion by 2040.

Owing to the mushrooming demand for these devices from the younger population, especially the millennials. Moreover, the soaring population in several countries will further boost the demand for customer electronic devices across the world.

Due to these factors, the global light sensor market attained a valuation of $1,456.2 million in 2019 and is predicted to advance at a CAGR of 9.5% during the forecast period (2020–2030). Light sensors are extensively used for proximity detection, ambient light sensing, RGB (red, green, and blue) color sensing, infrared radiation (IR) detection, and gesture recognition. 

Amongst these, the ambient light sensing applications are expected to record the highest use of light sensors during the forecast period. This would because of the rising utility of this function in the healthcare and automotive sectors around the world.

Light sensors are widely used in consumer electronics, industrial, automotive, healthcare, and entertainment sectors. Out of these sectors, the automotive sector is predicted to observe the highest growth in the usage of light sensors in the coming years. This is mainly attributed to the increasing incorporation of advanced driver assistance systems (ADAS) in automobiles, which require light sensors for park assist, light sensing, and several other applications.
