Abstract

The invention relates to a lighting device, a driving method thereof and a distance measuring module. The lighting device includes a light emitting portion; a projection lens configured to project light emitted from the light emitting portion; and a switching section configured to switch the projected light between a first configuration for surface irradiation and a second configuration for pointirradiation. According to the lighting device, point irradiation and surface irradiation can be achieved, and meanwhile size reduction and price reduction are facilitated.

Description

technical field [0001] The present technology relates to a lighting device, a driving method thereof, and a ranging module, and in particular, to a lighting device, a driving method thereof, and a ranging module capable of contributing to downsizing and price reduction while realizing point illumination and surface illumination. Background technique [0002] In recent years, due to the development of semiconductor technology, the size of the ranging module used to measure the distance to an object has also been reduced. Therefore, for example, smartphones mounted with distance measuring modules are also sold. [0003] A Time of Flight (ToF) ranging module irradiates light to an object and detects light reflected from the surface of the object, thereby calculating a distance to the object based on a measurement value obtained by measuring the time of flight of light. [0004] In the case of employing point light as the irradiating light to the object, there is an advantage i...
