Title:
LIGHT EMITTING DEVICE, DISTANCE MEASURING DEVICE AND MOBILE PLATFORM
Document Type and Number:
WIPO Patent Application WO/2021/068212
Kind Code:
A1
Abstract:
A control device for a light emitting device and a method therefor. The light emitting device comprises at least two laser emitting lines, and each of the laser emitting lines comprises a power supply, a laser emitter, an energy storage module, and a control module; and the power supply stores energy for the energy storage modules, and the energy storage modules supply power to the laser emitters. The at least two laser emitting lines share the power supply. The method comprises: for each of the laser emitting lines, adjusting the output provided to the energy storage module by the power supply in the present laser emitting line. Thus, a means of adjusting the emission voltage or light emission energy of different laser tubes is provided to thereby ensure the consistency of the light emission power of various lasers. At which time, all light emission powers may be adjusted to be near the safety limit, thus increasing the measurement distance of the entire machine.
