Document Type and Number:
WIPO Patent Application WO/2022/261835
Kind Code:
A1
Abstract:
The present application provides a light emitting device and a control method therefor, a distance measuring device, and a movable platform, the light emitting device comprising: one charging circuit, which comprises a power source and at least one charging element connected to the power source; and at least two groups of emission components, which are connected to at least one charging element, the at least one charging element being used to supply power to the at least two groups of emission components, so that the at least two groups of emission components emit in sequence light pulse sequences, and the power supply being used to charge at least one charging element by means of the same charging circuit before the at least one charging element supplies power to different emission components. The light emitting device of the present application simplifies circuits, has a simple structure, reduces hardware costs and is easy to control.
