Automatic light sensors help to conserve energy, whether on electronic devices or lighting a whole house. In addition to smartphones, automatic light sensors are used in electric light bulbs and other lighting devices and have the potential for use in other daily-use appliances as well. Light sensors decrease the demand for power and thereby conserve considerable amounts of energy.
The automatic light sensors in smartphones reduce the requirements for power. Thus, they increase the battery life of the phones by regulating the lighting to provide just the necessary amount of light.
In LCD Televisions
Automatic light sensors in LCD televisions could help regulate the LED backlighting to provide just the required amount of light.
In Lighting Rooms
The application of automatic light sensors to rooms having solid-state lighting (SSL) could help regulate the incident light by making adjustments on the basis of the natural lighting of the room.
In Vehicle Lighting
Automatic light sensors in vehicle lighting can help mirror the street lights and reduce the need for more lighting. This can, in turn, save a considerable amount of energy and power.
