Light sensors are installed in consumer electronic devices like smartphones and tablets to control automatic screen brightness and other features, which require the light to be sensed. The adoption of these electronics will escalate, on account of high demand from young population, especially the millennials. With a boom in the world population, the penetration of these devices will increase in the future.
Owing to this reason, the light sensor market will accelerate at 9.5% CAGR during 2020–2030. According to PS Intelligence, the market generated $1,456.2 million revenue in 2019. Apart from this, light sensors are also consumed in large quantity in the automobile industry. The automakers install these devices in the advanced driver assistance systems (ADAS) for park assist and to sense the light.

Moreover, the integration of internet of things (IoT) technology in ADAS devices has led to the increased adoption of light sensors in these devices. Besides, the light sensing systems also find applications in the healthcare, industrial, and entertainment sectors. Likewise, in January 2020, Vishay Intertechnology Inc. launched a line of integrated RGBC-IR color sensors that contain amplifiers, photodiodes, and analog/digital circuits. These devices can sense blue, green, red, and infrared (IR) light.
Further, these color sensors can be used for color cast correction and automatic white point balancing in digital cameras, automatic liquid crystal display (LCD) backlight adjustment, and active monitoring of light-emitting diode (LED) color output in smart lighting and IoT devices. Other companies producing advanced light sensors include Sharp Corporation, Maxim Integrated Products Inc., Broadcom Inc., and STMicroelectronics N.V.
