Light sensors

2024: Global Light Sensor Market Size Reaches $4.41 Billion for the Year

In 2024, sales of light (light) sensors on a global scale amounted to $4.41 billion. More than 40% of global spending was in the Asia-Pacific region. Such data are contained in a Fortune Business Insights study, the results of which were published in early November 2025.

Light sensors are widely used in a wide variety of fields, including consumer electronics, automotive, industry and urban infrastructure. In particular, in mobile gadgets, for example, smartphones and tablets, such sensors serve to automatically adjust the screen brightness depending on external conditions for comfortable use and save battery power. In vehicles, these sensors are responsible for automatically turning on the headlights, and in smart city systems, the lights. In the field of industrial automation, light sensors can be used to monitor color tags, control production processes, etc.

One of the market drivers, the authors of the study call the development of consumer technology and medical systems. Light sensors are used in photopletismography complexes: this is a method of recording the amplitude of blood volume fluctuations in vessels by translucent tissue. Photopletismography is used to record heart rate, assess heart rate variability, and measure other circulatory parameters. The sensor can be mounted on the finger or earlobe. In addition, there are devices for occlusive photoplethysmography using a tonometric cuff applied at the level of the upper third of the shoulder. The growing popularity of wearable health and physical activity monitoring devices is further driving the demand for light sensors. In general, the expansion of the digital health ecosystem and the need for non-invasive monitoring of vital signs of the body open up ample opportunities for the use of light sensors in diagnostics and wearable medical devices.

The integration of artificial intelligence has a positive impact on the industry. Neural networks allow you to increase the accuracy and efficiency of processing data from sensors. In the case of vehicles, this improves decision-making and improves safety. Generative AI in industrial environments provides predictive maintenance by identifying latent patterns in sensor readings to predict equipment failures.

By application, the market is segmented into consumer electronics, automotive, industry, healthcare and other areas (agriculture, street lighting, etc.). In 2024, the first of the listed sectors provided the largest share of revenue - 43.81%. Geographically, the Asia-Pacific region is leading with 43.3%, or $1.91 billion. The list of significant industry players globally includes:

• ams Osram AG;
• STMicroelectronics;
• Broadcom;
• Vishay Intertechnology;
• Sharp;
• Analog Devices;
• Everlight Electronics;
• Texas Instruments;
• ON Semiconductor;
• Rohm;
• Panasonic Holdings;
• Renesas Electronics;
• Melexis NV;
• Lite-On Technology;
• Sensortek.

In 2025, the light sensor market size is expected to reach $4.89 billion. At the same time, the Asia-Pacific region will have $2.16 billion, Europe - $0.93 billion, the United States - $0.91 billion. Fortune Business Insights analysts believe that in the future, the CAGR will be 11.82%. Thus, by 2032, costs may increase to $10.68 billion.^[1]
